Measures for the implementation of nucleic acid detection for epidemic prevention and control in COVID-19

In order to guide all localities to carry out epidemic monitoring in COVID-19, implement the requirements of early detection and early reporting, and timely discover and dispose of the epidemic, these measures are formulated.

I. Normalization monitoring

In areas where no epidemic has occurred, nucleic acid testing shall be carried out for risk posts and key personnel in strict accordance with the scope determined by the novel coronavirus Prevention and Control Plan (Ninth Edition) (hereinafter referred to as the Ninth Edition Prevention and Control Plan), and the scope of nucleic acid testing shall not be expanded. Generally, nucleic acid testing shall not be carried out for all employees according to administrative regions.

(1) Examination of medical personnel.

Medical personnel of various medical institutions at all levels, especially primary medical and health institutions, should raise their awareness of finding and reporting COVID-19 cases, paying special attention to the following situations.

1. Strengthen the monitoring of symptoms such as fever, dry cough, fatigue, sore throat, hypoesthesia and diarrhea, and carry out Covid-19 nucleic acid detection for all patients with fever. Suspicious patients who have no fever but have symptoms such as dry cough, fatigue, sore throat, decreased sense of smell, diarrhea, etc., have a history of epidemiology in COVID-19, or are engaged in risk occupation personnel (see the following classification of risk occupation population) should carry out nucleic acid detection in time.

2. Carry out nucleic acid detection on cases of unexplained pneumonia and severe acute respiratory infection in hospitalized patients.

3. Carry out nucleic acid detection on all newly admitted patients and their accompanying staff. After suspicious patients are found in community health service stations, village clinics and individual clinics, they should report to community health service centers or township hospitals within 2 hours, and implement the nucleic acid detection strategy of "village report, township sampling and county detection", which can simultaneously carry out antigen detection and find the epidemic situation as soon as possible.　

(2) Detection of occupational groups at risk.

Nucleic acid detection is carried out once a day for people who are in direct contact with entry personnel, articles and environment (such as passengers, cleaning and maintenance personnel of cross-border vehicles, porters of imported articles at ports, frontline personnel of customs and immigration management departments who are in direct contact with entry personnel and articles), staff in centralized isolation places, medical staff in designated medical institutions and fever clinics of general medical institutions.

For employees with dense working environment, frequent contacts and strong mobility (such as express delivery, take-away, hotel service, decoration and loading and unloading service, transportation service, supermarket and agricultural (gathering) trade market staff, etc.), port management service personnel and staff of other departments of general medical institutions except fever clinics, nucleic acid detection is carried out twice a week. After 1 case or more local epidemic occurs within the jurisdiction, the frequency of nucleic acid detection shall be encrypted according to the risk of epidemic spread or the requirements of local epidemic prevention and control.

　 　 (three) personnel testing in key institutions and places.

Schools, kindergartens, old-age care institutions, service institutions in the field of child welfare, psychiatric hospitals, training institutions and other key institutions, supervision places, production workshops, construction sites and other crowded places should do a good job in monitoring the symptoms of relevant personnel under normalization, and organize nucleic acid sampling according to local prevention and control needs. After 1 case or more local epidemic occurs within the jurisdiction, the whole staff should be organized to complete the nucleic acid detection in time, and then the nucleic acid detection can be carried out according to the detection results and the spread risk of the epidemic, according to the sampling ratio of at least 20% per day or the detection requirements of the jurisdiction.

(4) Community management crowd detection.

1 into the community management of COVID-19 discharged (cabin) infected people and their residents, in the third and seventh days after discharge (cabin) to carry out a nucleic acid test.

2. Carry out "five-day home health monitoring" for employees in high-risk posts who have finished closed-loop operations, and manage them with codes during the period. Conduct nucleic acid testing on the first, third and fifth days respectively, and don’t go out unless necessary.

3. Carry out "7-day home isolation medical observation" for the overflow personnel in high-risk areas, during which they are assigned code management and are not allowed to go out, and carry out nucleic acid detection on the first, third, fifth and seventh days of home isolation. The management period is from leaving the high-risk area to 7 days. After the investigation and discovery of the inflow place, the nucleic acid test should be carried out immediately for the overflow personnel, and then carried out at the required frequency; When the spill situation is found in the investigation, if the spill personnel have left the high-risk area for more than 7 days, it is not necessary to conduct home isolation after completing the nucleic acid detection immediately.

4. For those who spill in low-risk areas, complete nucleic acid detection twice within 3 days, with an interval of 24 hours.

5. For those exposed in epidemic-related places, nucleic acid detection shall be carried out on the first and third days after judgment.

6. Close contacts and entry personnel released from centralized isolation shall be tested for nucleic acid on the first and third days of home isolation respectively.

7. Other personnel who need investigation shall carry out nucleic acid detection and health monitoring according to the requirements of territorial prevention and control. After the risk personnel are found in the investigation or investigation, the nucleic acid test will be carried out immediately.

(5) Testing of drug purchasers.

After the occurrence of local epidemic, pharmacies in the jurisdiction should register the people who buy antipyretic, antiviral, antibiotic, cough and cold drugs with real names and push them to the streets (communities) in the jurisdiction, and urge users to carry out nucleic acid testing in time, and if necessary, carry out antigen testing first.

(6) Detection of cross-regional floating personnel.

In accordance with the principle of "voluntary, free, take and go, without restricting the flow", nucleic acid sampling points are set up in airports, railway stations, long-distance passenger stations, provincial service areas of expressways, ports and other places to provide "landing inspection" service for migrant workers across provinces and guide go on road trip personnel to take the initiative to carry out nucleic acid testing everywhere.

Passengers are required to take planes, high-speed trains, trains, inter-provincial long-distance passenger cars, inter-provincial passenger ships and other means of transportation with negative proof of nucleic acid test within 48 hours. People leaving the land border port city must hold a negative nucleic acid test certificate within 48 hours.

Check the health code and negative proof of nucleic acid test within 72 hours for people staying in hotels and entering tourist attractions.

Special people such as infants under 3 years old can be exempted from checking the negative certificate of nucleic acid test.

Second, regional nucleic acid detection

In the process of epidemic disposal, on the basis of epidemiological investigation, the range, frequency and sequence of the detection population are determined according to the size of the population in the epidemic area, whether the source of infection is clear, whether there is a risk of community transmission and whether the transmission chain is clear. If individual cases and asymptomatic infected persons have a low risk of transmission to their residence, workplace and activity area, and close contacts have been controlled in time, regional nucleic acid testing may not be carried out after judging that there is no risk of community transmission.

(1) provincial capital cities and cities with a population of over 10 million.

　 　 After the outbreak of the epidemic, after investigation, it is found that the transmission chain is unclear, there are many risk sites and risk personnel, and the risk personnel are highly mobile, and there is a risk of spread of the epidemic, all the people in the epidemic area will be tested once a day. After three consecutive nucleic acid tests without social infection, all the people will be tested once every three days, and all the people without social infection can be stopped.

　 　 In other areas where infected people have frequent activities and stay for a long time, a certain area can be designated to carry out full-time nucleic acid testing based on the flow survey. In principle, once a day to carry out full-time nucleic acid testing, three consecutive nucleic acid testing without social infection, you can stop full-time nucleic acid testing.

　 　 When an epidemic situation spreads widely in communities across regions, the command will be upgraded, and the provincial epidemic prevention and control mechanism will decide whether to carry out full-scale nucleic acid testing within the city.

　 　 (2) Ordinary cities.

　 　 After the outbreak of the epidemic, after investigation, it is found that the transmission chain is unclear, there are many risk sites and risk personnel, and the risk personnel are highly mobile, and there is a risk of spread of the epidemic, all the people in the urban area where the epidemic is located will be tested once a day. After three consecutive nucleic acid tests without social infection, all the people will be tested once every three days, and all the people without social infection can be stopped.

　 　 In areas outside the city, based on the flow survey, a certain area is designated to carry out all-staff nucleic acid testing. In principle, once a day to carry out full-time nucleic acid testing, three consecutive nucleic acid testing without social infection, you can stop full-time nucleic acid testing.

　 　 (3) Rural areas.

After the outbreak of the epidemic, it is found that the transmission chain is unclear, there are many risk sites and risk personnel, and the risk personnel are highly mobile, and there is a risk of spread of the epidemic. The natural villages involved in the epidemic, the location of the township government and the county where it is located, will carry out full-time nucleic acid testing once a day. After three consecutive nucleic acid tests without social infection, the full-time nucleic acid testing will be carried out once every three days. If there is no social infection, the full-time nucleic acid testing can be stopped.

When the epidemic spread to several towns and villages, based on the flow investigation and judgment, expand the scope to carry out all-staff nucleic acid testing. In principle, once a day to carry out full-time nucleic acid testing, three consecutive nucleic acid testing without social infection, you can stop full-time nucleic acid testing.

Annex 2

COVID-19Delineation and control scheme of pneumonia epidemic risk area

In order to guide all localities to divide the risk areas in the handling of the epidemic situation, effectively implement the relevant prevention and control measures in the risk areas, and minimize the impact of the epidemic situation on people’s production and life, this plan is formulated in accordance with the requirements of laws, regulations and documents such as the Law on the Prevention and Control of Infectious Diseases in People’s Republic of China (PRC), the Law on Basic Medical Care and Health Promotion in People’s Republic of China (PRC), the Emergency Regulations for Public Health Emergencies, and the Notice on Further Optimizing the Prevention and Control Measures for the Epidemic Situation in COVID-19, and combining with local experiences and practices.

First, scientifically define risk areas

Adhere to the principle of "prevention first, combination of prevention and control, scientific according to law, classification and classification", and realize the organic combination and rapid transformation of normalized accurate prevention and control and epidemic emergency response. Once a local epidemic occurs, the counties (cities, districts and banners) where the cases and asymptomatic infected people are located should be accurately divided into high-risk areas and low-risk areas as soon as possible, all forces should be coordinated, classified management measures should be implemented, the risk level and control measures should be updated dynamically in time according to the epidemic situation, and released to the public on their own initiative. In the process of handling the epidemic situation, if the spread risk of individual cases and asymptomatic infected persons to the place of residence, work place and activity area is low, and the close contacts have been controlled in time, the risk area may not be designated after judgment that there is no community spread risk; Counties (cities, districts and banners) that have not experienced local epidemics should earnestly implement various measures for the prevention and control of normalized epidemics, and there is no need to delimit risk areas.

(1) High-risk areas.

1. Classification criteria. In principle, the living places of infected people, as well as areas such as workplaces and activities with frequent activities and high risk of epidemic spread, are classified as high-risk areas. High-risk areas are generally defined by units and buildings. In the case that the risk of epidemic spread is not clear or there is widespread community spread, the scope of high-risk areas can be appropriately expanded. The scope of risk area can be dynamically adjusted according to the results of flow investigation and judgment.

2. Prevention and control measures. The implementation of the closure control measures, during which "never leave home, door-to-door service". If new infected persons are found during the containment period, the local joint prevention and control mechanism will organize risk judgment, and the containment time of the original containment area can be extended in whole or in part according to the requirements of "one area, one policy".

3. lift the standard. No new infections were found in the high-risk area for five consecutive days, and all the people in the high-risk area were negative after completing a round of nucleic acid screening on the fifth day, which was reduced to a low-risk area. High-risk areas that meet the conditions for unsealing should be unsealed in time.

(2) Low-risk areas.

Other areas of counties (cities, districts and banners) where high-risk areas are located are designated as low-risk areas. Implement "personal protection and avoid aggregation" and leave the city with a negative nucleic acid test certificate within 48 hours.

After all high-risk areas are removed, the counties (cities, districts and banners) will implement normalized prevention and control measures.

(three) the main considerations for the delineation of risk areas.

Delineation of high-risk areas and low-risk areas shall be carried out by the expert group organized by the prefecture-level epidemic prevention and control command department according to the spread risk of the epidemic, and the provincial joint prevention and control mechanism (leading group and command department) shall be commanded and given professional guidance and support. Specifically, the following factors can be comprehensively considered:

1 cases and asymptomatic infected people living conditions, living environment, natural barriers around the residence (roads, rivers, mountains and rivers, etc.).

2. Population protection, population gathering, cases and the frequency of contact between asymptomatic infected people and other personnel in the relevant areas.

3. The time and scope of work and activities of cases and asymptomatic infected persons, as well as the tightness and ventilation of relevant places.

4 after the discovery of the epidemic began to investigate the time interval, etc.

(four) confirmed cases and asymptomatic infected persons in the following circumstances are not included in the risk area determination.

1. Confirmed cases and asymptomatic infected persons found during centralized isolation medical observation have no risk of transmission outside the centralized isolation point after investigation and evaluation.

2. The confirmed cases and asymptomatic infected persons found during the observation of home isolation medicine have no risk of transmission outside the home after investigation and evaluation.

3. The confirmed cases and asymptomatic infected persons found during the strict closed-loop management of employees in high-risk positions have no risk of transmission by people outside the closed-loop after investigation and evaluation.

4. After discharge (cabin), those who are positive for nucleic acid detection have no risk of transmission after investigation and evaluation.

5. Ct value of nucleic acid detection ≥ 35, and was screened as a previously infected immigrant.

Two, clear working mechanism and division of responsibilities

The prevention and control of high-risk areas and low-risk areas shall be under the unified command of the prefecture-level epidemic prevention and control command department. Community prevention and control offices are set up in communities where high-risk areas are located, and generally there are working groups such as comprehensive coordination group, health monitoring group, medical security group, disinfection group, transshipment group, logistics security group, and security protection group to coordinate streets (towns), communities (villages), public security, health and wellness, disease control, development and reform, commerce, industry and informatization, housing and urban-rural construction, transportation, market supervision, group organization, and so on. The responsibilities of the working groups are as follows:

(1) Comprehensive coordination group. Mainly responsible for assisting the responsible comrades of the community prevention and control office to do a good job in overall planning and coordination, and do a good job in information collection and release, personnel investigation, and nucleic acid detection organization.

(2) Health monitoring group. Mainly responsible for residents’ health monitoring and health education. 　　　

(3) medical security group. Mainly responsible for providing medical services and psychological support, etc., and cooperating with the transfer of medical personnel who go out for medical treatment.

(4) disinfection group. Mainly responsible for disinfection and terminal disinfection of key parts and areas.

(5) transshipment group. Mainly responsible for the transfer of those who are positive for nucleic acid testing, those who have COVID-19-related symptoms, close contacts and those who go out for medical treatment.

(6) Logistics Support Group. Mainly responsible for the supply of living materials, garbage sorting and removal.

(7) security team. Mainly responsible for the patrol in the area, the management of bayonet closure, assisting personnel in the investigation, and organizing nucleic acid detection.

Third, implement community prevention and control measures by classification

(1) High-risk areas.

1. The area is closed. Arrange 24-hour patrol duty, strengthen management by installing monitoring equipment, electronic door magnets, etc., prevent people from going out and flowing, and strictly stay indoors. For those who really need to go out for medical treatment, they must be coordinated and arranged by the community prevention and control office, and a special car should be implemented to provide personal protection and implement closed-loop management.

If the high-risk area is located in the urban-rural junction or rural areas, the sanitary conditions are insufficient, the management is difficult, and there is a high risk of transmission. Residents in the area can be transported to centralized isolation places (if necessary, at most one person can be left in each household). At home, do a good job in environmental disinfection, room ventilation and other measures.

2. Publicity and guidance. Through WeChat, SMS, WeChat official account, small speakers, a letter and other means, timely release of the information and related arrangements. Guide residents to implement the requirements of personal protection and room ventilation. Pay close attention to and respond to residents’ demands in time to jointly create a good atmosphere for prevention and control.

3. Personnel touch the platoon. Through door-to-door visits, the establishment of WeChat groups, and checking the information of water meters and meters, we can find out the base number of all people in high-risk areas as soon as possible, and timely grasp the situation of elderly people living alone, minors, pregnant women, disabled people, people with mobility difficulties, hemodialysis patients, mental disorders, chronic diseases and other people. Timely grasp the situation of quarantined personnel who have not been transferred, implement special management and strict control, and strictly implement prevention and control measures such as staying at home, door-to-door sampling and health monitoring before transfer.

4. Health monitoring. Health monitoring shall be carried out for all personnel in high-risk areas, and the daily zero report system shall be implemented. Carry out temperature test and symptom inquiry once every morning and afternoon, understand the use of antipyretic, cough and cold, antibiotics, antiviral and other drugs by all personnel, and fill in the "Top Ten Symptoms" health monitoring registration form. If symptoms such as fever, dry cough, fatigue, sore throat, decreased sense of smell (taste), nasal congestion, runny nose, conjunctivitis, myalgia and diarrhea are found, the health monitoring group will immediately report and arrange home nucleic acid detection.

5. Nucleic acid detection. Carry out three consecutive tests in the first three days after the implementation of the closure control, complete two full-time nucleic acid tests on the first and third days, and carry out one antigen test on the second day. The frequency of subsequent tests can be determined according to the test results; Within 24 hours before the deregulation, the whole staff should be tested for nucleic acid once. When carrying out nucleic acid detection, it is necessary to set up sampling points reasonably and enable them after being evaluated by professionals; Scientifically determine the route, strengthen on-site organization and management, implement special guidance, time-sharing and zoning, and fix the route, and urge personal protection to prevent cross-infection. For buildings and courtyards where positive infected people have been found, antigen testing can be carried out first, and then nucleic acid testing can be carried out in an orderly manner after negative. Special personnel, such as risk personnel who have not been transported, those who are positive for antigen detection and nucleic acid mixed tube, patients with mobility difficulties and the elderly, should be sampled at home and single sampling and single inspection should be carried out.

6. Personnel transfer. If the personnel in the high-risk area are judged as close contacts, they will be transported to the centralized isolation place within 8 hours. Those who are found to be positive for nucleic acid test will be transported to designated medical institutions within 2 hours. Relevant personnel should strengthen local control before transshipment, and strengthen the personal protection of transshipment personnel and staff during transshipment.

7. Environmental disinfection and monitoring. Strengthen the disinfection of key areas and key parts, and disinfect key areas such as van elevators (corridors) and key parts such as elevator buttons, stair handrails and unit door handles that people frequently contact. Carry out terminal disinfection in time and evaluate the disinfection effect of cases and asymptomatic infected persons in places such as residence, work and activities. Strengthen disinfection personnel training, technical guidance and supervision and evaluation.

8. Garbage sorting and removal. Standardize the setting of temporary collection points for domestic waste and medical waste. Garbage generated by those who are positive for nucleic acid testing and close contacts and protective articles used by staff shall be treated with reference to medical waste. Other garbage can be treated as "other related domestic garbage" according to the requirements of "disinfection first and double bagging" after unified collection, so as to achieve "daily production and daily cleaning" and keep the environment clean and hygienic.

9. Living materials and medical security. Deploy forces, make it clear that the special team is responsible for the supply of basic living materials for residents, and do a good job in demand collection, help purchase and delivery to households. The local epidemic prevention and control command department should coordinate the development and reform, commerce, public security, transportation and other departments, smooth the transportation channels, promote the security supply units and large supermarkets to strengthen the docking with the community, and timely distribute relevant materials; It is necessary to designate specialized medical institutions to provide medical services for residents in high-risk areas, promote the establishment of a docking mechanism between communities and specialized medical institutions, and provide medical convenience for elderly people living alone, minors, pregnant women, disabled people, people with mobility difficulties, hemodialysis patients, mental disorders and patients with chronic diseases.

10. Psychological assistance and social work services. Inform people in high-risk areas of the telephone number of psychological assistance hotline, provide psychological support, psychological counseling and other services, alleviate negative emotions, prevent and alleviate psychological distress caused by the epidemic, and prevent extreme events caused by psychological pressure. When people in high-risk areas are found to have mental health problems, they will be referred to their counterparts’ mental health medical institutions in time.

(2) Low-risk areas.

1. Strengthen social control. All kinds of personnel in the area shall carry out nucleic acid testing as required, and try to reduce going out, not gathering and not getting together during the period, and do personal protection when going out; Strictly implement measures such as booking, peak shifting, current limiting, temperature measurement, registration and wearing masks when entering indoor public places.

2. Personnel investigation and control. After receiving the information on the investigation of the overflow personnel in the high-risk area, the investigation of the risk personnel should be completed within 24 hours, and the personnel management, health monitoring, nucleic acid detection, personnel transfer and other work should be coordinated; For those who cannot be investigated, timely feedback should be given to form a closed loop of investigation.　

3. Traffic control. People in low-risk areas advocate not to leave the area unless necessary, and cross-city mobility must hold a negative nucleic acid test certificate within 48 hours. Vehicles and personnel who transport production, living, medical protection materials and engage in "point-to-point" transshipment of road transportation shall be guaranteed to pass smoothly on the basis of strictly implementing various prevention and control measures such as disinfection and closed management. Strengthen the control of traffic checkpoints in railway stations, airports, highways, waterways and other access areas, and do a good job in temperature measurement, verification and code inspection.

4. Nucleic acid detection. According to the risk assessment results of epidemic spread and the management of risk personnel, scientifically determine the population range and frequency of nucleic acid testing in low-risk areas. When carrying out nucleic acid detection, sampling points will be set up nearby and will be activated after being evaluated by professionals; Strengthen on-site organization and management, carry out in an orderly manner, avoid gathering, and urge personal protection.

5. Health education. Strengthen health education, remind residents to reduce going out, avoid gathering, keep social distance and do personal protection. After symptoms such as fever, dry cough, fatigue, sore throat, decreased sense of smell (smell), stuffy nose, runny nose, conjunctivitis, myalgia and diarrhea, they should take the initiative to go to medical institutions in time. Do a good job in propaganda and guidance of prevention and control policies, so that residents can actively cooperate with the investigation of risk personnel.

See attached table for delineation and control measures of high and low risk areas.

　　　　Fourth, strengthen organizational guarantee

(1) Improve the working system.

Establish a "three-level guarantee" system, give full play to the role of grassroots party organizations, and implement county (city, district) cadres to cover streets (towns), township (street) cadres to cover communities (villages) and administrative villages (communities) cadres to cover households. Establish a "five-package one" system, and refine the division of responsibilities. Street (township) cadres, community grid administrators, grassroots medical workers, police, volunteers, etc. are jointly responsible for implementing community prevention and control measures, so as to achieve "five in place" of education, investigation, control, supervision and care. Establish a multi-sectoral communication and consultation mechanism, strengthen communication and coordination between the community and local health, disease control, public security and other joint prevention and control related units, and form a joint force for epidemic prevention and control. Hospitals and disease control institutions should give full play to their professional advantages and provide support for the community to do a good job in personnel control, health monitoring, nucleic acid detection, personnel transfer, cleaning and disinfection.

(2) Reasonable staffing.

Counties (cities, districts), streets (townships) and communities (villages) should be equipped with prevention and control personnel and medical prevention and control materials according to the needs of local community size and epidemic prevention and control work. County (city, district) and above epidemic prevention and control command departments should make overall arrangements for prevention and control personnel in high-risk areas. In principle, staff in high-risk areas should be equipped according to the proportion of not less than one tenth of the number of residents, and cadres of relevant units in provinces and cities can sink to each working group to carry out their work.

(3) Do a good job in training drills.

Strengthen staff training, so that they can fully grasp the knowledge, policies and personal protection skills of prevention and control in COVID-19, define the work requirements, and scientifically and accurately implement various prevention and control measures. After the issuance of this plan, all localities should strengthen training drills, improve the working mechanism in time, and master the prevention and control measures and requirements in different risk areas.

(4) Strengthening staff management.

Staff should do a good job in the corresponding level of protection according to the exposure risk specification, and complete the whole vaccination of Covid-19 vaccine before taking up their posts. Staff in high-risk areas should be managed in a closed way during their work, and they should do a good job in health monitoring and maintain a certain frequency of nucleic acid detection, and conduct home health monitoring for 5 days after work.

(five) to strengthen the protection of living materials.

The epidemic prevention and control headquarters at or above the county (city, district) level shall, jointly with relevant parties, establish a cross-regional cooperation mechanism for joint supply and protection of materials, with the development and reform, commerce, transportation and other departments taking the lead, responsible for the overall planning, procurement, allocation and transportation of materials, supporting relevant enterprises to play the role of supporting the bottom, strictly enforcing the law, stabilizing prices, and doing a good job in docking with community prevention and control offices, unblocking green channels, and fully ensuring the supply of living materials for residents.

(6) Actively create "epidemic-free communities".

Adhere to scientific and precise requirements, implement various prevention and control measures with high standards, timely and dynamically adjust the corresponding prevention and control measures for those who have not had an epidemic and meet the lifting standards, fully mobilize the enthusiasm of community residents to participate in and cooperate with prevention and control work, enhance the confidence and determination of cadres and the masses to overcome the epidemic, restore normal production and living order in time, and make overall plans for epidemic prevention and control and economic and social development.

(7) Do a good job in supervision and inspection.

All localities should strengthen the supervision and inspection of community prevention and control work, and the county (city, district) and above party committees and governments should organize a supervision team to establish a daily supervision and inspection mechanism and regularly report the inspection and rectification. For counties (cities, districts) where the epidemic occurs, they can take the form of stationing supervision in relevant key areas to urge the local authorities to effectively implement various prevention and control measures.

Annex 3

Medical observation guide for home isolation of epidemic situation in COVID-19

I. Management object

Including special people among close contacts, close contacts and entry personnel after lifting centralized isolation, overflow personnel in high-risk areas and other personnel who cannot be subjected to centralized isolation medical observation after professional evaluation.

Second, the site requirements

(a) home isolation medical observers had better live alone; If conditions do not allow, choose a well-ventilated room in the house as an isolation room and remain relatively independent.

(2) Put tables and stools outside the relatively independent isolation room as the junction of non-contact transfer items.

(3) When the room is ventilated by air conditioning system, split air conditioning should be selected. If central air conditioning is used, the air conditioning can operate normally, the fresh air volume should be increased, and the return air should be closed by the whole air system.

(four) if conditions permit, try to use a separate bathroom and avoid sharing the bathroom with other family members.

(five) the room should be equipped with personal protective equipment such as thermometers, paper towels, masks, disposable gloves, disinfectants, disinfection products and garbage cans with covers.

Third, the management requirements

(1) community service requirements.

1. register. Street (town), community (village) staff should get in touch with home isolation medical observers in time, master the information of home isolation medical observers, check whether the living place meets the conditions of home isolation medical observation, issue a notice of home isolation medical observation (see Annex 1), inform the relevant requirements of home isolation medical observation, and register in accordance with the requirements of "one file for one household" or "one file for one person" and incorporate it into community grid management. Master the situation of special personnel in home isolation medical observation, such as elderly people living alone in empty nests, patients with basic diseases, pregnant women, hemodialysis patients, etc., establish a ledger, and do a good job in necessary life support and care services.

2. Monitoring information collection. Streets (towns) and communities (villages) can regularly inquire and collect the temperature, symptoms and other information of medical observation personnel in home isolation twice a day in the morning and evening. If anyone with fever, dry cough, fatigue, sore throat, decreased sense of smell, diarrhea and other symptoms is found, report it immediately, and contact 120 negative pressure ambulance by a special person and send it to a fever clinic or designated medical institution according to the principle of proximity.

3. Nucleic acid detection. The nucleic acid detection during the observation period of home isolation medicine is collected by community sampling personnel at home, and the results of nucleic acid detection are pushed in time.

4. Environmental cleaning and garbage disposal. Disinfect the walkways, stairs and other places on the floor where medical observers live in isolation at home once a day, clean up the garbage at least once, and clean it up in time if necessary.

5. Psychological assistance and social work service requirements. Inform home medical observers of the telephone number of psychological assistance hotline, provide psychological support, psychological counseling and other services, alleviate the negative emotions of isolated personnel, prevent and alleviate the psychological distress caused by the epidemic, and prevent extreme events caused by psychological pressure. When mental health problems are found in home isolation medical observers, they should be referred to their counterparts’ mental health medical institutions in time.

6. Spot check regularly. The community should regularly carry out spot checks on the observers who are implementing home isolation medicine within their jurisdiction to find out whether they are conducting home isolation medicine observation as required, whether they leave their residence, whether they participate in gathering activities, and whether they complete nucleic acid detection and other activities on time.

7. Staff protection. When the community medical observation management personnel are in contact with the isolated medical observers at home, they should do a good job of self-protection when dealing with their pollutants and the surfaces of contaminated objects, and wear disposable working caps, medical surgical masks, work clothes and disposable gloves, keeping a distance of more than 1 meter from them. N95/KN95 particulate matter protective mask should be worn when transporting positive infected persons, handling infected persons’ pollutants and polluting the surface of objects, or being in close contact with isolators due to other work.

(2) Self-management requirements for medical observers in home isolation.

1. Health monitoring. Home-isolated medical observers should take temperature measurement and self-health monitoring once every morning and evening, and report the monitoring results to the community medical observation management personnel. During medical observation, if there are symptoms such as fever, dry cough, fatigue, sore throat, decreased sense of smell (taste), diarrhea, etc., the community management personnel shall promptly report to the local health administrative department and the disease control institutions under their jurisdiction.

2. No going out. During the period of home isolation, the code management is assigned, and the home isolation personnel strictly do not go out and refuse all visits. For those who really need to go out for medical treatment, they can go out only after being approved by the local community medical observation and management personnel, and arrange a special car to do personal protection and implement closed-loop management.

3. Personal protection. Non-single residents, their daily life and meals should be confined to the isolation room as far as possible, and other people should not enter the isolation room. You don’t need to wear a mask when you are in the isolation room, and you should wear a mask when you leave the isolation room.

The spring of online movies comes earlier and stronger than the natural spring in Jiachen. According to incomplete statistics, as of March 26th, Iqiyi, Tencent Video and Youku have accumulated 89 new online movies this year, with different types and excellent productions, which are welcomed by the market. Among them, the box office champion has accumulated more than 34 million yuan, and "The Story of Qiao Feng with Eight Dragons" has reached the big screen in some overseas countries and regions, becoming the box office champion of Malaysian New Year films and the box office champion of Singaporean Chinese New Year films. This gratifying scene has effectively boosted the morale of the industry and the confidence of practitioners, and stimulated people’s thinking about future development.

Creating Film Works Based on Internet Distribution and Communication

In 2014, the industry defined online movies: movies with a duration of more than 60 minutes, a complete movie structure and the Internet as the main distribution platform. At that time, with the deepening of industrialization reform, the film market in China showed a high growth momentum, attracting capital and talents. However, for a long time, the channel of film communication has been mainly concentrated in the cinema. Although the number of domestic cinema screens has increased steadily, there are still some films that cannot be released every year due to limited capacity. At this time, video websites rose rapidly, and the massive capacity and convenient viewing mode provided market space for movies. As a result, movies based on Internet distribution and communication appeared, and gradually formed an art category that was different from cinema movies in content and audience.

Due to the relatively low online cost of video websites, online movies attract a large number of small teams and new companies that pursue low investment and short cycle to seize the market. In order to form differentiated competition with cinema films, some producers regard the topics rarely involved in mainstream cinema films as competitiveness, and take the slant of the sword and attracting attention as the main topic selection direction. Creation mainly focuses on thriller, exotic animals, fantasy and other theme types, and repeatedly remake and interpret classic works or big IP. Some themes crash and the content is the same; Some works apply the titles and even themes of popular cinema films in the same period; Other works have sensational titles, exaggerated and explicit contents and unclear narrative logic. For a time, "low style", "shoddy", "love to rub hot spots" and "imitation and follow the trend" became the key words of online movies, which caused the audience to criticize. In response to this phenomenon, the relevant departments set about governance. On the one hand, scientific planning of topics, regulation of fantasy, animals and other overcapacity theme creation; On the one hand, it provides support for the main melody works that reflect real life and praise the great era in the aspects of auditing and project establishment, broadcasting and propaganda. In 2022, the State Administration of Radio, Film and Television issued an administrative license for online dramas, and online movies were certified to "take up their posts", leading the industry to advance to quality.

Explore the scientific accounting mode to make high-quality works get higher box office.

The direction of high-quality products is not only reflected in the continuous updating of creative ideas, but also in the improvement of industry rules. For a period of time, there is a saying in the industry that it takes three elements to make an explosion, namely the title, poster and 6 minutes. "6 minutes" is the time limit for free trial viewing. Once it exceeds 6 minutes, the system will prompt the audience to buy membership or pay for viewing, and the video platform will divide the account with the film according to this effective viewing quantity. This rule makes online movies fall into a "6-minute" cycle. In order to get more points, some works put most of their production funds and creative energy into the first six minutes of creation, so that wonderful content, hot scenes and dazzling special effects can erupt in a concentrated way. The creation beyond 6 minutes is fooled, either "water injection" or "unfinished", and the quality declines in a cliff-like manner, which makes the audience feel cheated.

In order to solve this problem, the industry is constantly trying to explore a new accounting mode, and adjusting "effectively watching the accounting according to the first six minutes" to "long accounting on time" and "long accounting on time". Take the new regulations issued by iQiyi in 2024 as an example. Members watch for more than 10 million hours, more than 6 million hours and less than 6 million hours, and the corresponding 10,000-hour ladder bill prices are 3 yuan, 2 yuan and 1 yuan respectively, and the final total box office is the sum of the income of each ladder. In order to avoid intentionally filling the film with water, some video platforms refine the calculation method of effective duration. For example, the audience watches a 60-minute movie at twice the speed, and the final effective duration counted by the platform is 30 minutes. This means that the "key time" to attract users to watch is no longer the first 6 minutes. The longer users watch, the higher the income of film producers. In order to incite a higher box office, the film must produce high-quality content that can stand the test of the audience.

Actively respond to the changing market environment and establish new differentiated advantages.

In the past two years, online movies have encountered new challenges. On the one hand, the window period of cinema movies is shortened, which brings competitive pressure to online movies. Window period refers to the time interval required for a movie to play content in different media. Earlier, after the film was shown in the cinema, it was not broadcast on the streaming media platform until at least one month later. However, in recent years, the online speed of cinema movies has become faster and faster, which has broken this convention. Many users who watch movies on the Internet prefer to choose cinema movies that have passed the market test and accumulated a certain reputation and popularity. This has squeezed the market space of online movies to a certain extent.

On the other hand, the appearance of miniseries has a certain impact on the online movie market. Both of them are new film and television categories that have developed rapidly in the process of the rise of the Internet. They all make full use of the convenience and interactivity of online media, allowing viewers to watch online platforms anytime and anywhere, and they are good at attracting users by means of intensive burying and frequent inversion. However, the difference is that the mini-short drama can be displayed horizontally and vertically, and the length of a single episode is short, and the number of episodes can be more or less, which is easier to meet the entertainment needs of people watching in fragmented time by mobile phones. The online movie is mainly in horizontal screen mode, which is more suitable for the traditional deep viewing experience. If we follow the logic of realizing money completely, the miniseries whose current flow pool is larger than the online movie track are more attractive to the creators. In the past two years, the scale of online movie industry has declined. According to incomplete statistics, there were 245 online movies in 2023, a decrease compared with 2022, which should be related to the limited market space and the loss of talents to miniseries. Facing the changeable market environment, in order to achieve sustainable development, online movies should not only adhere to the quality of movies, but also tap the advantages of the network, so as to achieve new differentiated competition in the attack of miniseries and cinema films.

High-quality works intensively cultivated by professionals are constantly emerging.

Blowing out the wild sand begins with gold. Continuous policy guidance, resource pooling and concept updating have squeezed the market bubble of online movies, and pushed the industry onto a benign track of setting up professional creative teams, adopting scientific and standardized production processes and creating quality content products. In the spring of 2024, the online movie market achieved a bumper harvest at the box office, marking that online movies have entered a new stage of "improving quality and reducing quantity".

The market competition of online movies has changed from "invitational tournament" to "elimination tournament". Before that, speculators who regarded this track as a quick way to make money were gradually eliminated. Practitioners who adhered to the wrong ideas of attracting audiences and obtaining economic benefits by creating a sense of coolness and gimmicks also changed their thinking, and high-quality films were constantly emerging. Many creations have jumped out of the past, and turned to the themes of the times, such as poverty alleviation and rural revitalization, to show real life, historical events and cultural classics from a youthful and typed perspective, opening up more artistic space for mainstream value dissemination. For example, China Flash, Hidden Grass is Green, Black Hawk Boy and Huang Jiguang, a Superhero, etc., some of them have been listed in the prime file of TV, some have been selected as excellent network audio-visual works by the State Administration of Radio, Film and Television, and some have been highly rated on the rating website, which has been recognized by the mainstream media and praised by the audience. People are pleasantly surprised to find that in addition to "cool feeling" and "excitement", online movies can also see so many lovely and respectable characters, diverse and flexible artistic presentations and silent value expressions, which have a positive and far-reaching impact on the diversification of main theme film and television expressions from the aspects of theme content, style and communication channels.

In addition to deepening the theme creation, online movies also deepen the existing advantages. Unlike cinema movies, which have large screen capacity, richer picture expression and scene scheduling power, online movies are limited by screens of computers, mobile phones and other viewing terminals, and pay more attention to the detailed presentation of pictures and the drama of stories. Action movies have become a type suitable for this media and can create unique audio-visual effects on small screens. Many practitioners are deeply involved in this field. For example, in creation, works such as Warrior Company and Sniper Hero focus on the characters’ state of calmly fighting and confronting the enemy with neat and coherent movements at critical moments, so that the audience can truly feel the tense and exciting atmosphere of the battlefield and deeply understand the hero’s spirit of not being afraid of sacrifice. In planning, iQiyi launched the "Action Master Season", focusing on launching a number of action movies to create a publicity matrix.

In short, online movies have a "network sense" different from cinema movies and a "movie sense" different from mini-dramas. Therefore, we should meet the needs of network carriers in form and stick to the artistic quality of movies in content. With the establishment of a sound market mechanism, the improvement of comprehensive evaluation indicators and the improvement of the audience’s aesthetic needs, online movies will continue to play the role of theme test fields, talent Petri dishes and IP incubators for film and television production, and achieve quality and standardized development.

The big model will set off a new round of industrial revolution, and Internet applications will be reshaped. Zhang Chaoyang believes that we are in the eye of the storm and the center of AI, and communication and marketing have also entered a new field. Whether it is brand promotion or bringing goods, we must base ourselves on an account matrix and the "viral communication" generated by accounts. This is a new form of marketing.

　　According to IDC’s latest forecast, by the end of 2024, there will be more than 500 million new applications in the world, which is equivalent to the sum of the total number of applications in the past 40 years, highlighting the far-reaching impact of AI technology on enterprise development. In this context, AI applications based on big voice models have sprung up like mushrooms after rain, and a new ecology of account matrix promoted by enterprises in the AI era is gradually being built.

　　Wu Hequan, academician of China Academy of Engineering and director of internet society of china Expert Advisory Committee, emphasized the key role of AI Agent as the carrier of large-scale model landing in his keynote speech. He believes that domestic and foreign technology giants have laid out the field of agents and built their own agent development platforms to promote the wide application and commercialization of AI technology.

　　Facing the surging wave of AI era, Li Hui, vice president of ".Mobile" domain name registration authority, put forward innovative solutions at the meeting. He said that the ".mobile phone" domain name can quickly build an exclusive agent for enterprises through a number of ecological resources and relying on a unified underlying development architecture, effectively solving problems such as talents, technology and capital, and ensuring that enterprises can seize the dividend of the AI ? ? era. At the same time, the Chinese top-level domain name of ".mobile phone", as the unified entrance of enterprises, not only realizes the direct access to multi-platform applications such as enterprise agents, but also improves the user experience and brand communication efficiency.

　　Li Hui also said that with the accelerated transformation of artificial intelligence from "a hundred-mode battle" to "application is king", as the core application of AI, agents are gradually building increasingly rich application scenarios, clear business logic and perfect application ecology. This change not only promotes the application of artificial intelligence technology, but also provides a strong driving force for enterprises to reduce costs and increase efficiency, and transform and upgrade.

　　The guests at the meeting said that at the current stage, artificial intelligence is undergoing a strategic shift from "Hundred Models War" to "Application is King". As the core application of AI technology, agent has increasingly extensive application scenarios, clearer business logic and more mature application ecology. This change not only makes artificial intelligence move from abstract character data to visualization, but also gradually transforms it into a new quality productivity that promotes enterprises to reduce costs and increase efficiency.

When the car is constantly pursuing more seats, it shows a different side in the market segment. In the same spacious carriage, the less, the more advanced the product positioning. Therefore, in some mid-to-high-end products that have been or will be listed in the near future, many products are not limited to launching regular 7-seat models, and fewer 6-seat or even 4-seat models have begun to be welcomed by consumers.

In the new generation of product planning, there are three versions of 7 seats, 6 seats and 4 seats. At present, the main models on the market are 7-seat models, even the GL8 Avenir Avia models with high-end positioning are 7-seat models. However, recently, the official map of a new generation of GL8 Avenir Avia six-seat version has been officially released, which also indicates that it is a step closer to the launch of this new car.

Configuration is more luxurious than the current Avenir.

It is worth mentioning that the new generation GL8 Avenir Avia six-seat version is not just as simple as replacing the current model with two independent seats. From the seven-seat version to the six-seat version, it is obviously upgraded from the perspective of product positioning, so we see that the configuration of the new car has also been greatly upgraded from the inside out, showing the style of luxury.

The new generation GL8 six-seat model is classified as Avenir Avia series, so all the unique designs of the current Avenir Avia series have been preserved in new cars, such as chain mail-style China Net and exclusive Merlot wine red. At the same time, the new car has also been upgraded. At first glance, the new car is equipped with a brand-new Matrix all-crystal diamond headlight composed of eight "diamond crystals". This upgrade not only improves the visual effect, but also realizes eight intelligent lighting modes in actual lighting function. In addition, ADB’s anti-glare high beam function has 18 high beam lighting zones, which cooperate with high-definition wide-view forward camera to help improve driving safety at night. As an echo, the taillight style of the new car has also become a suspended arrangement style of 11 spar, which is like a stretched wing after lighting.

In order to show luxury, the new generation GL8 Avenir Avia six-seat model also provides exclusive dynamic concierge lights with rich styles. At the moment when the electric door is opened, Avenir Avia’s exclusive welcome blanket shines out, and with Avenir Avia’s exclusive lighting welcome pedal, every boarding is honored.

Inside the car, the second row of seats is consistent with the current model with high standards. Different from the 7-seat model, the 6-seat model also provides independent seats with high comfort for the third row passengers. The seat can adjust the front and rear distance by 160mm, and is equipped with 6-speed adjustable independent handrails, 146-degree super-large chair back inclination angle, heating/ventilation function and dual USB charging interfaces.

The six-seat version is a more practical choice.

From the perspective of improving the sense of luxury, the new generation GL8 Avenir Avia six-seat model with higher positioning will obviously be better than the seven-seat model. But this is not just the only purpose of the six-seat model.

In the real use scenario, the current GL8 Avenir Avia seven-seat version can only provide the most distinguished ride experience in the second row. Although it’s okay to ride, you will never let your guests sit in the third row during business reception. However, the six-seat model is different. Although it is still slightly different from the second row, it is still equipped with many comfortable and practical configurations, which can at least realize the reception of some VIPs. In other words, the seven-seat model can only receive two VIPs, while the six-seat model can receive four VIPs, which is the practicality of the six-seat model.

If you consider more, the six-seat model can also be exempted from the annual inspection, which also makes the car more simple and worry-free.

Write it at the end

From the perspective of the new generation GL8 Avenir Avia, the author thinks that the upcoming six-seat model will be more practical than the current seven-seat model. At the same time, for the mid-to-high-end market, the launch of the new generation GL8 Avenir Avia six-seat edition will re-establish a new standard for large luxury. (Text/Zhong Yi)

foreword

"Green wave belt is a concept that has existed in the transportation industry for a long time. Daily interaction relies on its long-term technical accumulation in big data and artificial intelligence. By fusing and calculating its own data, traffic control department data and third-party data, it integrates cycle time, surrounding scenes, road traffic direction, driving speed and other factors. The algorithm is used to calculate the best signal and control parameters, quickly form an urban green wave scheme, and can be dynamically adjusted according to the real-time traffic flow and road conditions on the road. In the case of having as little impact on the surrounding traffic as possible and making maximum use of the existing transportation infrastructure, the complexity of green wave signal control coordination and optimization is greatly reduced, allowing the traffic control department to dispatch and manage the traffic flow of the road network with a click of the mouse, so that "Photoshop" can be turned into "Meitu Xiuxiu" in seconds. At the same time, it helps the urban traffic control department to build a digital traffic management system at a very low cost, and quickly improves the fine and intelligent water of urban road traffic signal control. Realize "100 times efficiency" with "100% rate", help the construction of a transportation power, and create a safe, orderly, smooth and civilized road traffic environment for the masses to travel. "

Special thanks to the Hangzhou traffic police. Hangzhou is the first city where our number of smart green waves have landed. It is also under the trust and professional guidance of the Hangzhou traffic police that we have really polished this product and continuously optimized it. Since October last year, we have co-created and strengthened the construction of green wave belts with the traffic police brigades of Hangzhou districts, changing the original mode of setting up long-distance green wave belts, turning 3-5 intersections into a group, turning lines into faces, and increasing the speed by about 20%. At present, there are more than 200 green wave belts built in Hangzhou, with a mileage of more than 300 kilometers, all over the urban area of Hangzhou. In their daily travel, Hangzhou citizens have unknowingly enjoyed the smooth convenience brought by the green wave belt.

Yesterday, Fang Yi, founder and CEO of Daily Interactive, accepted Love’s analysis and systematically shared his views and successful practices on urban traffic congestion management.

Fang Yi

Founder and CEO of Daily Interactive

Outstanding graduate of Zhu Kezhen College of Zhejiang University. Winner of the 4th "Youth May 4th Medal" and winner of the 10th "Youth Entrepreneurship Award".

The current executive committee of the All-China Federation of Industry and Commerce, the National Association for Science and Technology, the National Youth Federation, the Vice of Young Entrepreneurs, the National Information Security Standardization Technology Association, the Vice of Zhejiang Youth Federation, the Vice of Zhejiang Federation of Industry and Commerce (Provincial Chamber of Commerce), the Vice of Zhejiang Chamber of Commerce, the Vice of Hangzhou Federation of Industry and Commerce, and the Hangzhou CPPCC. The founded Daily Interactive successfully landed in the growth enterprises market in 2019 (code: 300766), becoming the first data intelligence enterprise in China to list on class A shares.

01 Urban traffic congestion management is the world’s most prominent problem in urban diseases, and daily interactions seek new breakthroughs in solutions

Love Analysis: Big report, we need to speed up the construction of a transportation power and figures, and improve urban water governance. Traffic congestion, as the most prominent and most global problem in "urban diseases", is very realistic and challenging to manage. At present, what are the common painpoints in the traffic control department in optimizing urban road condition management and serving citizens’ travel?

Fang Yi: Big, to accelerate the construction of a transportation power and digital, the Ministry of Transport and the Ministry of Science and Technology have also jointly issued the "Opinions on Accelerating the Construction of a Transportation Power Driven by Scientific and Technological Innovation" and the Outline of the Medium and Long-term Development Plan for Scientific and Technological Innovation in the Transportation Field (2021-2035). The development of the strategy and related policies has provided a good policy environment for the development of our data intelligence field and pointed out the development direction.

During the "14th Five-Year Plan" period, our country’s economy will transition to high-quality development, and the volume of passenger and freight transportation will continue to grow. The main problems facing transportation governance are poor traffic flow in the core areas of cities and insufficient smart transportation coordination. According to official statistics, the number of cars in 70 cities in our country has exceeded 1 million. Traffic congestion is the most common, most frequent, most prominent and most world-wide problem in urban diseases, and its governance is very realistic and challenging. According to field observations and industry exchanges, we found that the current traffic control departments generally have the following pain points in optimizing urban road condition management and serving citizens’ travel:

First of all, the number of urban cars in our country, the number of drivers surged, the urban population continues to increase, traffic facilities gradually complex, but the city’s intersections, road sections of the digital construction is still not high, the lack of intelligent traffic coordination, data sharing system has not yet formed, resulting in the city’s overall road conditions online monitoring and analysis is difficult, single point intersection timing intelligent low, many intersections often empty or congestion phenomenon.

At the same time, traffic control departments are mostly based on manual experience, lack of big data support, and the effect of intersection signal timing after manual adjustment cannot be quickly and accurately verified. Closed-loop iterative optimization is difficult to achieve, and there is a lack of sufficient coordination between different intersections and regions. It is difficult to cope with the complex traffic conditions that change in real time throughout the region. Unreasonable single-point green signal ratio settings will have a significant impact on the traffic efficiency of intersections.

At present, many cities commonly use Australia’s SCATS (Sydney Coordinated Adaptive Traffic System) and Europe’s SCOOT (Split Cycle Offset Optimizing Technique) system, its timing capabilities, adaptive capabilities, although very powerful, but data collection through urban roads coil or geomagnetic induction to achieve, its ground sensing equipment is often due to urban road planning adjustment, perennial traffic flow and frequent damage failure, and SCATS and SCOOT system is not "intelligent", timing personnel need "code level" ability, through the input of complex code scripts for timing, the use of high threshold, and the system for traffic police repeated temporary adjustment without "memory ability", it is difficult to precipitate experience, the formation of "reuse", can not flexibly respond to the ever-changing urban traffic conditions.

Finally, the investment in transportation infrastructure in various cities is huge, with hundreds of thousands of intersections at every turn. It is difficult to get through the data of different suppliers. The cost of "one game of chess" transportation intelligence in the entire city and region is high, and the hardware investment is large and the effectiveness is small.

In view of the above situation and pain points, Daily Interactive hopes to use cutting-edge technologies to assist in the innovation of traffic management concepts, management methods, and management models, and to improve the modernization, informatization, and intelligent water of traffic governance. This year, Daily Interactive has created a "Digital Smart Green Wave" product (hereinafter referred to as "Digital Smart Green Wave") for the field of smart transportation. This product can help the traffic police department to efficiently complete the intelligent timing of signal lights and the intelligent coordination and optimization of green wave routes, and realize the digital construction and intelligent scheduling management of road network traffic flow, better serve citizens’ travel, and improve the traffic management water in various cities.

In early 2022, Wenzhou City, Zhejiang Province plans to build (Wenzhou) Data Intelligence and Security Service Innovation Park (ie "Shu’an Port"). Daily Interactive has been deeply involved in it in the early days. When Shu’an Port is completed and operated, "Smart Transportation" happens to be released as Scenario 001. We hope that by relying on the establishment of Shu’an Port, we can make full use of our massive and vivid mobile Internet big data and capabilities, and deeply integrate multi-party dynamic data from traffic management departments, map service providers, and third-party data intelligence service providers for joint calculation, build a localized business system, and provide traffic management tools for traffic control departments to carry out intelligent application in the field of smart transportation.

Love Analysis: Compared with the traffic lights and manually coordinated green wave belt solutions of the traditional timing scheme, what innovations and breakthroughs have been made in solving the above pain points of the traffic control department by the "digital intelligence green wave" advocated by Daily Interactive?

Fang Yi: The so-called green wave belt is not a new concept, but a concept that has existed in the field of transportation for a long time. It refers to the fact that on a designated traffic line, when a vehicle travels at a specified speed, the signal controller adjusts the green light start time of each intersection that the traffic flow passes through according to the distance of the road section, so as to ensure that when the traffic reaches each intersection, it just encounters the "green light", thereby improving the overall traffic efficiency of the traffic line.

Our "digital intelligence green wave" product will use big data intelligent means to analyze the comprehensive traffic flow at intersections, optimize the single-point green signal ratio, improve the utilization efficiency of intersections under large traffic flow, and screen out the traffic arterial intersections suitable for the construction of green wave belts. By considering factors such as cycle time, surrounding scenes, road traffic direction, and driving speed, the algorithm is used to calculate the best signal and control parameters, increase the green wave coordination control, and ensure the smooth passage of vehicles on regional arterial roads by accurately segmenting the timing of intersection signals, thereby reducing delays and stopping times, and achieving the goal of "stop at most once".

The biggest feature of the daily interactive "Digital Intelligence Green Wave" product is to connect and connect the data layer, and conduct data mining and analysis of traffic scenes such as traffic flow distribution, signal control characteristics, intersections and road characteristics, providing traffic distribution, green wave recommendation, green wave optimization and other service components, and then support specific operations such as intersection/road network visualization configuration and intersection coordination relationship research and judgment in specific traffic management applications, so as to achieve "data characterization, feature serviceization, and service application", allowing urban traffic control departments to analyze, respond to, and monitor road conditions in real time, especially for traffic police to quickly and dynamically adjust the timing of intersection lights under their jurisdiction according to real-time road conditions.

Compared with the traditional timing scheme, the "digital intelligence green wave" product can be quickly optimized according to the traffic flow data of the road surface, rather than the "fixed" scheme under the traditional timing, which is more practical and flexible; compared with the manually coordinated green wave scheme, the "digital intelligence green wave" product is supported by traffic flow data and intelligent algorithms, reducing the heavy dependence on expert experience, and the operation is simpler. There is no need for the front-line traffic police to master complex codes. After only one hour of simple training, the front-line traffic police can master the system proficiently, and can realize the one-click configuration of the green wave scheme. It can also be used to fine-tune single intersections and road sections by dragging and dragging. At the same time, digital intelligence green wave can be based on the overall coordination and control of the entire region to avoid the overall inefficiency of regional traffic caused by the lack of systematic thinking and local optimization of various intersections and road sections.

02 Daily interactive "Digital Intelligence Green Wave" products help urban transportation upgrade from "manual transmission" to "automatic transmission"

Love Analysis: What is the general working principle of the "Digital Intelligence Green Wave" product? During this process, what core resources and technical capabilities have been mobilized by Daily Interaction to ensure the intelligence, efficiency and safety of the "Digital Intelligence Green Wave" product?

Fang Yi: Our "Digital Intelligence Green Wave" product, combined with Internet big data, provides personalized green wave signal control solutions in time periods, and conducts regular monitoring of green wave road sections, and makes decision-making and timing for green wave solutions that meet requirements, so as to realize the digitalization of road network traffic flow and intelligent scheduling management. Specifically, it can be understood from the following aspects:

Figure: Schematic of the solution architecture of the daily interactive "digital intelligence green wave"

Our "Digital Intelligence Green Wave" product uses big data joint computing as the underlying infrastructure to maximize the security of data flow computing. This is because, although the massive data of daily interaction is given to the system at the statistical level under the green scene, which fully complies with the requirements of the Personal Information Protection Law, Data Security Law and other relevant regulations, it also needs to integrate the data of the traffic control department and even third parties. Therefore, it needs to enter the private network through the border and integrate the data in the private network for computing to provide services for upper-level applications. In order to ensure product and data security, all the data are put on the state-owned big data joint calculation for joint calculation, to ensure that the original data source can enter and exit, can be counted and not recognized, can not be used, the algorithm is transparent and easy to supervise, and the calculation is safe and efficient.

In terms of basic capabilities, Digital Intelligence Green Wave connects with rich data sources, and uses a powerful system inside Daily Interactive – "DiOS Data Intelligent Operating System" for data governance and fusion calculation, generating signal control scheme suggestions. We use our own big data to perceive real-time traffic flow data on the road, and at the same time, under the coordination of the traffic control department, we will also access the traffic control department’s road network basic data (such as traffic lights, lane lines, etc.), traffic police business data, infrastructure sensing data, etc. for fusion calculation and cross-validation. In the future, it may even be integrated with more third-party maps and data from travel service providers, so that the traffic control department can make a more three-dimensional judgment on traffic flow and road conditions. So how do we manage and calculate so many sources of complex data? This requires the use of the DiOS data intelligent operating system. DiOS can fully mobilize the company’s core capabilities in digital modeling, security computing, visual intelligence, intelligent transportation, etc., perform fusion calculations on the basis of data governance of all parties, and "scene" all kinds of traffic data. It is used to analyze and mine the traffic flow characteristics and travel OD characteristics of various intersections, road sections, and regions, so as to generate corresponding signal control scheme suggestions, and provide simulation components to facilitate the simulation and prediction of the effects of different signal control schemes.

In terms of business applications and empower, our digital intelligence green wave is connected with SCATS and other systems through API and RPA, so as to carry out real-time transmission and execution of signal control solutions and support automatic delivery. At the same time, based on the regional and road network traffic characteristic data, the daily interaction provides functional modules such as road network housekeeper, signal control optimization, green wave, cockpit, operation monitoring, etc., which can perceive, analyze, and dynamically adjust and optimize the information control measures of the road network. Based on the above functional modules, the urban traffic control department can easily implement three-dimensional business applications such as macro-urban planning suggestions to mid-scale road network construction guidance and digital intelligence green wave services through self-filtering maps, green wave design, program delivery, effect prediction and optimization.

It is worth mentioning that the digital intelligence green wave can also carry out the overall coordination and system optimization of regional traffic in a "game of chess" style. In order to avoid the green wave belt in a certain direction destroying the traffic efficiency of the road crossing it, when the horizontal road is made into a green wave belt, our "digital intelligence green wave" product supports a traffic light intersection as the center, and all intersections in the area are aligned with it, so that the intersecting routes and directions can be matched into green wave belts to carry out the overall optimization of regional traffic "game of chess". Of course, traffic is impermanent, and traffic flow is constantly changing in real time. Therefore, the digital intelligence green wave must have the ability to respond to emergencies and continuously iterate and optimize. In the actual traffic management process, it is not realistic to pursue green lights at all intersections. Here, the traffic control department needs to make value judgments. In order to prevent the situation of "snakehead biting snake tail", Digital Intelligence Green Wave also supports "temporary solutions". Once a temporary emergency such as a traffic accident occurs at an intersection or road section, the signal light control can be quickly restored to the original state. When the temporary emergency is over, it can be restored to the green wave state, thereby eliminating traffic pressure. In addition, Digital Intelligence Green Wave can also use technologies such as short-term flow forecasting and variable lanes to make intelligent iterations of the green wave solution and build a closed-loop urban traffic management business.

Finally, it comes to the specific use level. One of the major advantages of our digital intelligence green wave products is the ease of use. The horizontal axis is a road, and the vertical axis is the time axis. When the left signal light phase is selected, the right signal light phase can be automatically aligned with one button. Through this relative alignment, the regional green wave band scheme can be quickly realized. With the assistance of the machine, the difficult "photoshop" can be changed into "Meitu Xiuxiu" in seconds, which greatly reduces the complexity of green wave signal control coordination and optimization, allowing the traffic control department to dispatch and manage road network traffic flow with a click of the mouse.

Love Analysis: What are the core values of "Digital Intelligence Green Wave" products for urban traffic management and people’s livelihood? What kind of cities and road sections are they mainly suitable for?

Fang Yi: From the working principle above, you can see that our "Digital Intelligence Green Wave" product is based on the Internet-side big data fusion calculation, and builds urban green wave belts at a very low cost to help urban traffic control departments build digital traffic management systems, perceive and analyze road profiles in real time, and provide rational construction suggestions to quickly improve the fine and intelligent control of urban road traffic signals, creating a safe, orderly, smooth and civilized road traffic environment for the masses to travel.

It is worth mentioning that our "Digital Intelligence Green Wave" product does not waste any sensors, but makes maximum use of the existing existing facilities and aggregates the data together to achieve "cross-domain data fusion" to provide mutual verification for the urban traffic control department. For example, in case of some extreme situations, the daily interactive traffic flow data changes rapidly, and the traffic control department can use its own data to calibrate the daily interactive traffic flow data; similarly, the daily interaction can also infer the unreasonable traffic facilities data of the traffic control department, and then complete it.

Figure: The main advantages of the daily interactive "Digital Intelligence Green Wave" product

From the perspective of the scope of application, as long as it is a road section that has realized online control, it has the application basis of "digital intelligent green wave". At the same time, the daily interactive "digital intelligent green wave" product has its own set of metrics, such as the repetition rate of the number of vehicles entering a certain intersection and leaving the intersection, etc. We will make a comprehensive judgment based on the location of the road section and surrounding facilities. For example, we find that a road section is equivalent to a tunnel, and the repetition rate of cars entering and leaving is very high. Then we consider this road section to be a commuter road and suitable for green wave belts.

Love Analysis: It is understood that the daily interactive "Digital Intelligent Green Wave" products have been launched in Hangzhou, Wenzhou, Huzhou and other cities, and have received good feedback. So, can you systematically introduce the company’s construction ideas when helping urban traffic control departments implement the "Digital Intelligent Green Wave" project?

Fang Yi: From a physical perspective, the construction ideas of our Digital Intelligence Green Wave project can be divided into the following steps to achieve a closed loop from concept communication, diagnosis, design planning to scheme optimization and solidification.

The first is the concept submission. We will first throw out our understanding of urban traffic management, fully discuss with the traffic control department, and promote the two sides to reach an agreement on the concept; then, we will clarify the daily interaction based on the underlying data to empower the front-end business with intelligent algorithms, emphasizing the traffic control department, especially the front-line traffic police as the user experience, from the traditional industrial control field thinking mode to the Internet-oriented C-end thinking mode, improve the ease of use of the front end, and do not need to change any of the original urban traffic construction plan, which can be completed at a very low cost.

The second step is to start planning and design. The daily interactive "Digital Intelligence Green Wave" product uses the data of mobile Internet big data, traffic police departments and map service providers to automatically jointly calculate and generate roads suitable for green wave construction in cities, and supports manual intervention of recommended green wave road sections, which can be added, deleted and modified according to the actual situation. For example, in the Hangzhou Green Wave Belt project, we found more than 700 kilometers of roads suitable for green wave construction in Hangzhou based on our own measurement standards, and submitted their distribution map to the Hangzhou traffic control department for review and discussion.

The next step is to configure the green wave. Digital Intelligence Green Wave can combine road network data and data such as the speed and flow of corresponding road sections and intersections to intelligently recommend a number of road sections that are most suitable for the construction of the green wave belt, and calculate detailed green wave configuration plans to assist in the final green wave belt construction decision. The traffic police department can select specific road sections for the "green wave scheme" effect experience according to our recommendation results. Then, we use visual intersection stewards to achieve comprehensive input and visual display of green wave construction information such as signal infrastructure, channelization, and flow; at the same time, the road network stewards will integrate information such as road section length, historical vehicle speed, and road section characteristics to generate intelligent recommended vehicle speeds, providing speed guidance for the design of the green wave scheme and ensuring the green wave effect.

Next is the division of time periods and scheme design. Speaking of which, we have to mention the great advantage of our smart green wave products that are easy to use. Smart green wave supports the adjustment and optimization of green wave bands by simple dragging on the time and distance diagram. It can be adjusted individually according to different scenarios (schools, scenic spots), different time periods (morning, evening peaks, daytime peaks), different periods (working days, weekends), etc., and multiple green wave scheme designs for specific intersections and road sections can be carried out. The optimal green wave scheme can also be selected according to the monitoring data and control experience of the traffic control department on specific road sections.

Single-point optimization is also very valuable. In this link, we can combine intersection flow data, intersection characteristic data and intersection signal control data, and accurately optimize the single-point signal control scheme of all intersections in the area to produce a single-point recommended timing scheme divided by time period, which can be automatically or manually issued, or sent to the signal light control system after manual intervention of the single-point recommended timing scheme.

Finally, to the practice running and program optimization, solidification link. We will assist the traffic control department to optimize the overall and single-point green wave scheme in the selected road section for partial or comprehensive practice running, and real-time operation monitoring of the program effect, according to the actual regional, road network program application and then optimized, submitted to the city traffic control department for confirmation, so as to achieve the solidification of the green wave scheme for different intersections and different time periods.

Figure: Daily interactive intelligent green wave belt construction idea schematic

In addition, from the perspective of specific service methods, the daily interactive "digital intelligence green wave" project construction process includes four steps of pilot mode, deployment, product use training, and product optimization and upgrading. During the pilot period, the daily interaction can provide some selected road sections of green wave belt construction and promise corresponding results, providing free training and free product iteration and upgrade services during the maintenance period.

Love Analysis: Can urban transportation be graded with reference to autonomous driving? What is the significance of this in helping smart city governance upgrade?

Fang Yi: Just as autonomous driving can be divided into five levels according to the degree of autonomy from "fully manual to fully automated", we believe that the degree of digital intelligence in urban traffic can also be graded according to the degree of intelligence in the control of traffic lights at various intersections in the city. Therefore, we have developed the "Smart Transportation 6L" classification concept.

Figure: Daily interactive "Smart Transportation 6L" grading concept

Level L1 means that there are signal lights at the intersection, which can be used for basic traffic control. Level L2 means that the signal lights at the intersection are connected to the Internet, and the traffic police can issue instructions remotely for single-point regulation. Level L3 is based on L2, and can perceive digital information such as the queue length and speed at the intersection through radar, cameras, geomagnetism and other equipment installed at the intersection, as well as big data on the Internet. Level L4 can analyze and model the data uploaded at the intersection to form a dynamic, data-guided closed-loop control. Level L5 is based on L4 to realize intelligent coordination of multiple intersections, such as the construction of "digital intelligence green wave belt". Level L6 is to achieve intelligent road management and control, that is, based on data modeling and analysis of regional road characteristics, business districts, schools, etc., it can achieve fine coordinated control of multiple intersections and comprehensively improve regional road functions.

The development process and scale of cities in our country vary greatly, and the investment progress of transportation infrastructure varies widely. Even in some relatively developed cities in the south, a large number of signal lights in the city may still be single-point level and have not been networked. Through the "Smart Transportation 6L" grading concept, the daily interaction can be based on the same language and measurement system with local traffic control departments to help cities find the specific coordinates of different intersections and road sections, and combine the urban transportation construction plan and budget of the year to communicate the upgrade plan of different intersections and road sections, such as upgrading from L1 to L2, or directly skipping to L3. At the same time, based on the agreed upgrade path, the daily interaction can complete the intelligent upgrade of urban transportation facilities at designated intersections and road sections within a certain period of time as agreed, and cooperate with cities to flexibly arrange the upgrade progress. This can greatly reduce the pressure on fiscal expenditure in each year, making the intelligent upgrade of urban transportation visible, controllable, and low-cost. It is expected that the daily interactive "digital intelligence green wave" products will initially be centered on the Yangtze River Delta and then rolled out nationwide.

03 Daily Interaction empowers domestic traffic intelligence with data intelligence core capabilities

Love Analysis: What are the plans for daily interaction in the future in terms of digitalization and intelligent upgrading in the field of transportation?

Fang Yi: In the field of transportation, we mainly have the following two aspects of planning:

In terms of urban transportation, as mentioned earlier, daily interaction will use big data in a very convenient way to achieve initial intelligence of urban transportation. The current is the "smart green wave" solution, and in the future, daily interaction will also use Wi-Fi sensing systems or other new road condition sensing systems in a more refined way, coupled with big data to close the loop, greatly reducing the construction cost of intelligent urban transportation.

In terms of high-speed transportation, Daily Interactive is currently cooperating deeply with Zhejiang Gaoxin Technology joint stock company, a subsidiary of Zhejiang Jiaotong Investment, to help it further deepen its expressway informatization business with DiOS data intelligent operating system; at the same time, Daily Interactive also uses its own technical capabilities to create an early warning system for abnormal situations on expressways, and actively participates in the management of abnormal situations such as highway throwing. Specifically, we use the high-speed "gantry" ETC data to calculate the instantaneous speed of each vehicle entering and leaving and the interval speed between the two gantries, and according to the speed and traffic flow changes between the gantries, combined with expressway cameras, quickly find problems on specific sections of the expressway and give timely warnings to reduce the risk of expressway accidents. At present, the early warning system for abnormal conditions on expressways has been able to detect abnormal sections in about one and a half to two minutes, and inform the expressway traffic police two to ten minutes before the accident so that they can arrive at the abnormal section in advance and quickly for processing. In the future, the daily interaction will further dig into the management scene of high-speed traffic, and continue to work hard to improve the informatization of expressways and reduce the accident rate of expressways.

Love Analysis: What other perspectives do you want to share on road network digitalization, urban transportation governance, and other aspects?

Fang Yi: Now there is a new trend in traffic governance to apply radar and video, but the cost and edge computing cost of this solution are relatively high. In recent years, our domestic computing resources have been greatly improved, but the computing power is ultimately limited, and the rational use of computing power resources has become the key to reducing costs and increasing efficiency. I think that many vehicles, especially new energy vehicles, are constantly emitting various wireless signals such as Bluetooth and Wi-Fi. If traffic management departments build wireless signals to build sensing devices above the ground rather than underground to manage traffic, the difficulty and cost will be much lower, and it will become a new paradigm.

"Digital Intelligence Green Wave" is the result of daily interaction and innovation for people’s livelihood needs. With the general trend of accelerating the construction of a transportation power, a network power, and digital, we are on the road of data intelligence at the right time, hoping to drive more social changes with data intelligence in the future.
