Cctv news(Reporter Wang Xiaoying) The safe operation of every train is inseparable from the dispatching signal of the rear train, and it is the on-board signal equipment on the train that accepts the dispatching signal.

　　Therefore, the on-board signal equipment on the train is very important, and it is known as the "black box" on the train. The staff of Lanzhou Electric Section of Lanzhou Bureau of China Railway Group, their task is to check whether the "black box" is running normally after the train enters the station.

　　In recent days, the temperature in Lanzhou has been high for several days. For the staff of Lanzhou Electric Power Section, it can be said that they have entered the "cooking" mode. When checking the "black box", they have to bear the high temperature of more than 70 degrees, and often they have not checked for a few minutes, and their bodies are soaked.

Chen Feifei and his colleagues are checking the car signal equipment.

　　The highest temperature is as high as 70 degrees.

　　"Pay attention to the speed limit ahead" and "Pay attention to the crossing" … … These passwords are transmitted to the train cab in real time through the on-board signal equipment.

　　For Chen Feifei and them, the main job is to check whether the on-board signal equipment is normal after the train runs. If the on-board signal equipment is not working normally and the train can’t receive the signal, the train may become "blind", so it is necessary to check the train regularly according to a certain period.

　　When the running train ended and returned to the warehouse for maintenance and preparation, Chen Feifei and his colleagues began to be busy.

　　However, in hot weather, the train runs at high speed for a long time, the environment is closed, high-power electrical equipment heats up, and the train is exposed to the outdoor environment with high temperature for a long time, which leads to the continuous high temperature in the train cab.

　　How hot is it in there? Chen Feifei’s colleagues brought two thermometers. In their working environment, the thermometer with the highest scale of 50 degrees has been "off the charts", and the other thermometer shows a temperature of 73 degrees when it is close to the equipment.

The thermometer has been "off the charts"

　　For Chen Feifei and them, they have already started to check, and they are sweating like a pig, and the sweat of the bean will drip down.

　　Climbing the roof and drilling the bottom of a car need to check 35 items.

　　Chen Feifei’s vehicle-mounted equipment workshop in Lanzhou, lanzhou railway administration, has a total of 16 people, who are responsible for the inspection of 309 passenger locomotives and 14 groups of motor trains. These trains are mainly bound for Beijing, Shanghai, Wuhan, Xuzhou, Zhengzhou, Xi ‘an, Hohhot, Xining and Urumqi.

　　Sixteen people rotate in three shifts every day, and five people are responsible for locomotive maintenance every day. The daily workload is 35-40 trains, and one person is responsible for 7-8 trains on average. Because of this, for Chen Feifei and them, the inspection should be started as soon as possible after the trains enter the depot, and they can’t wait for the trains to cool down.

The staff who are checking the equipment.

　　Cheng Wei, the foreman of Lanzhou Vehicle Equipment Workshop, introduced that checking the vehicle signal equipment of a car involves 35 projects, which are distributed on the roof, cab and bottom of the train. Among them, climbing the roof is mainly to check the wireless transmission antenna installed on the top of the locomotive, and drilling the bottom is mainly to check the installation and anti-dropping state of the electric vehicle-mounted equipment (including speed sensor and locomotive signal receiving device), to simulate the locomotive signal coding, and to accurately capture the abnormal shape of the equipment; In the cab, it is mainly to test whether the locomotive signal equipment, the train operation monitoring and recording device and the train wireless integrated communication equipment are normal, and also to prevent some screws, cable ties and other parts from loosening due to strong vibration all the time.

　　The inspection seems simple, but to climb the roof, drill the bottom of the car and get into the cab, they test and repair all parts of the equipment one by one according to the equipment maintenance process, some check the version data, and some check the equipment condition.

　　It takes at least half an hour to check a car. "The weather is particularly hot during the summer vacation. As small as a screw, a set of data, as large as a speed sensor and a host, it will affect the normal operation of equipment, especially for equipment that runs for a long time, and it is necessary to ensure its performance. Good." Chen Feifei said.

　　[original analysis of Aika automobile competitiveness]

　　Halfway through 2022, although the new energy market has been baptized by the epidemic, the momentum is still improving. Different from the past, traditional car companies began to compete with the new forces in building cars on the same track, trying to seize the next round of new energy outlets. When Japanese car companies, led by Honda and Toyota, use brand-new models such as e:NP series and bZ4X to incite the whole new energy market, regardless of the outcome of sales or the view that traditional car companies turn around like elephants, China’s new energy vehicle market has indeed added a dose of stimulants. And interestingly, everyone has targeted the new energy market around 200,000 yuan, which is the core battlefield in the future.

　　At present, the price of Guangqi Honda’s e:NP1 has fallen to 175,000-218,000 yuan, which is a confident judgment of its product strength, and will also indicate that Guangqi Honda will officially continue to consolidate its position in the China automobile market as a new energy player and reconstruct the new energy market in China. However, the continuation of the "Fuel Honda" DNA, is it really explosive?

　　The exploration of electrification has never stopped.

　　With the rapid growth of domestic new energy market, "electrification" has become the top priority of every car company’s future layout. Founded in 1998, Guangqi Honda has been deeply involved in the China market for 24 years and has never stopped exploring electrification. As early as 2016, Guangqi Honda Accord sharp hybrid model went on the market, and i-MMD hybrid system was introduced. With its characteristics of giving consideration to power output and fuel economy, it gained the trust of 300,000 users.

　　After a long-term exploration, Guangqi Honda has accumulated a profound "heritage" in the three-electricity technology. At the Honda China Electrification Strategy Conference in October 2021, Honda launched a brand-new electric brand — — E:N, "E" is energize (power) and electric (electric energy), and "N" stands for New (brand-new) and Next (evolution), indicating Honda’s determination to open up the future electric market, and the brand-new electric brand e:N is changing from "quantitative change" to "qualitative change".

　　Half a year later, Guangqi Honda’s brand-new electric brand e:NP (Chinese name: Jipai) was officially released, which is a symbol of Guangqi Honda’s comprehensive electrification. On the evening of March 29th this year, Zheng Heng, executive deputy general manager of Guangqi Honda, issued a declaration on the expedition of e:NP brand, "Extreme, Surging — — Extreme, contains our inner desire for the unknown; 澎湃 means the collision between inspiration and ideas. " Extreme Pai should not only inherit the driving pleasure and quality standards in the fuel age, but also have the face value and intelligence without losing new forces, aiming at breaking the boundary between fuel vehicles and electric vehicles.

　　Some people may question that without the roar of the engine and the sense of communication at the mechanical level, Honda’s brand-new answer sheet handed over in the electric age can still make Honda powder shout out the phrase "e:NP1 is best" again like VTEC, and continue to write the glory of the new brand?

　　What are the highlights of Extreme Pai 1?

　　● High face value

　　Jipai 1 is based on Honda e:N Architecture F’s brand-new intelligent pure electric architecture. It adopts a brand-new "e:N Design" design language, and the closed grille is painted in matte black, with simple headlight groups on both sides, which brings a good visual impact. In addition, the luminous "H" logo fits the avant-garde image of the electric car. The black plaque above the charging port is equipped with two light strips, which automatically light up when charging, and can display the energy flow, so the design details are full.

　　The body of Jipai 1 adopts two waistlines with obvious folding angles, creating a body posture with low front and high back, which strengthens the sports atmosphere. The tail is outlined with straight lines, creating a good sense of layering. The penetrating taillights have a strong three-dimensional shape and have a good family recognition after lighting. On the whole, the face value of Jipai 1 is really not low.

　　● Maximize the space of four wheels and four corners.

　　In addition to having a good face value, the space performance of Ji Pai 1 is also remarkable. Although it is positioned as a pure electric small SUV, the four-wheel and four-corner body design maximizes the interior space with a limited wheelbase. The visual effect is full and the body shape is very slender. Based on the e:N Architecture F platform developed by Honda, the battery pack height is lower, which makes it have better space performance.

　　Previously, my colleague had already experienced the space of Pai 1. The experiencer with a height of 1.75m sat in the main driver’s seat, and after adjusting the height of the seat to a suitable sitting position, his head had plenty of space.

　　Keeping the front seat position unchanged, the same experiencer sits in the back row, and the leg space has more than two punches left. In the same class, the performance of Jipai 1 is remarkable.

　　● Continue to write fuel Honda DNA with pure electricity.

　　Many consumers have said that due to the characteristics of electric vehicles, the acceleration of starting and braking will make them feel dizzy. In this regard, Honda engineers rely on years of endorsement in handling/power adjustment, and through repeated adjustment of the pedal response, power output characteristics, seat and suspension system of Extreme Pai 1, when the throttle is loosened or braked, the kinetic energy recovery system produces a slight drag feeling, so that drivers and passengers of Extreme Pai 1 will not feel dizzy and uncomfortable.

　　Extreme Pai 1 is equipped with a three-in-one high-power drive motor with a maximum power of 150kW(204 HP), which is equivalent to a 2.0T engine from the data point of view. It matches more than 20,000 motor control program algorithms in different driving scenarios, making it possible for Extreme Pai 1, although an electric car, to continue the "charm" of fuel Honda, without losing driving pleasure in daily driving. This is the driving pleasure that Honda still insists on in the electrical age when bidding farewell to VTEC.

　　Above, we have summarized and sorted out its outstanding advantages according to its product characteristics, so what are the shortcomings of Jipai 1? If you have different opinions, please leave a message in the comments section.

　　Is there a short board in Extreme 1?

　　● The function area in the central control panel has a sense of confusion, and the UI design is not advanced.

　　Extreme Pai 1 is equipped with a 15.1-inch ultra-large high-definition ultra-thin bezel central control panel, which is divided into three areas: upper, middle and lower. The upper part displays the application interface, the middle part is the menu, and the lower part is the air-conditioning control area. However, on the whole, the three areas in the ultra-large central control panel of Extreme Pai 1 are not integrated, some of them show a sense of confusion, and the UI design is not elegant enough, which is also a "common problem" existing in traditional car companies.

　　● The level of intelligence is lower than that of "new forces"

　　Jipai 1 comes from a traditional car company like Guangqi Honda, and there is still a certain gap in the level of vehicle intelligence, assisted driving, navigation and voice compared with the new force of car building. My colleague personally tested the car system of Jipai 1 during the test drive. Although the recognition rate and response speed of voice control function are remarkable, it also supports the automatic recognition of some keywords, but the automatic recognition of keywords needs to adapt to a period of time, and there are several cases of "uninvited" during the test drive.

　　In addition, the central control panel of Pai 1 can only display "full screen" when navigating the page, but it is actually only displayed in the "upper middle" two areas, and the bottom is still the air conditioning system control area. After entering the live mode, the real-time road conditions and navigation routes are projected on the central control screen, but unfortunately, the live navigation mode does not support "full screen" display.
