What's wrong with the "front" of the bullet train?

After a day's operation, the high-speed rail will return to the warehouse in turn for renovation and inspection at night to ensure the safe operation of the next day. During the period of Spring Festival travel rush, the frequency and intensity of EMU trains increased obviously compared with usual, which also put forward a great test for the on-board maintenance personnel of high-speed rail. At the grass-roots level during the Spring Festival, I met someone who operated on the train brain today. At 23 o'clock in the evening, the outdoor temperature in Shenyang has been as low as MINUS 20 degrees Celsius, and most people have fallen asleep. For Ren, who is 5 1 year old, the day's work has just begun. The foreman of the first-class repair work area of the on-board equipment workshop of Shenyang high-speed railway: 5768 arrival (warehousing) starts.

Ren is the foreman of the first-class repairman area of Shenyang high-speed rail vehicle equipment workshop. There are 22 employees in this work area, who are responsible for the inspection and maintenance of the on-board equipment of 49 sets of EMUs. Car safety computer commonly known as? Black box? It is the brain of EMU trains, which can record all kinds of operation data and fault codes. Therefore, Ren joked that he was an EMU train? Brain doctor? . As the foreman of the first-level repair work area of Shenyang high-speed rail vehicle equipment workshop, we carefully analyzed the data download, found out the hidden dangers, and dealt with them in a timely and targeted manner to ensure the safe and stable operation of the EMU high-speed rail. The temperature in the northeast is low and there is much snow. When the EMU trains return to the maintenance depot, thick ice and snow often condense under the carriages. In order to reduce the influence of ice and snow accumulation and speed up the maintenance progress, the temperature in the maintenance snow melting bin is set above 30 degrees, so as to realize ice melting and snow melting in the shortest time.

The foreman of the first-class repair work area of the on-board equipment workshop of Shenyang High-speed Railway: Generally, we often check the car in advance, and after the inspection, the snow on the car is almost less. We don't waste any time. In the sultry carriage, Ren was sweating profusely. After downloading the fault data, he began to analyze the data. Chief of the first-level maintenance work area of Shenyang high-speed rail vehicle equipment workshop: This data should show that there is no hardware alarm information, but the fault code displayed now has the problem of abnormal communication. Foreman of the first-class repair workshop of Shenyang high-speed rail vehicle equipment workshop: We have two sets of equipment for EMU trains. If the main engine fails, the standby machine will automatically enter the working state, which will not affect the safe operation of the EMU high-speed rail. But now there is a fault, and we must find the source through data analysis and deal with it. We must not let the car go on the road sick. According to the fault phenomenon and fault code, Ren found it quickly. Root of the disease? After data analysis, the faulty equipment is replaced, and the EMU train is completed. Brain surgery? . If you have no time to rest, you should immediately go to the bottom of the car body to repair the speed sensor, radar antenna and other equipment. The environment in the car is stuffy and hot, but the temperature under the car is extremely wet and cold because of the lack of ice and snow 10 degrees. Foreman of the first-class repairman area of Shenyang high-speed railway vehicle equipment workshop: It rained heavily today, and the speed was fast. The speed of high-speed rail is more than 300 kilometers per hour, which is often the case in bad weather. After this train inspection, I'm soaked inside and outside, and it's easy to catch a cold. I didn't adapt at first, but now I'm used to it. With the arrival of Spring Festival travel rush Peak, the maintenance tasks have also increased, and all 22 employees, including Ren, have started? Running mode? They complete the inspection and transformation of at least 27 sets of bullet trains every night. Wang Yong, a repairman in the first-class repair area of Shenyang high-speed rail vehicle equipment workshop: Every day, I have to run at least 10 km every day, so I am used to it. For Ren, the work of 15 years has made him go through the process of EMU train maintenance from imitation to absorption, from surpassing to leading. Ren said that through this work, he also felt the rapid development of China's high-speed railways.

The foreman of the first-class repairman area of Shenyang high-speed rail vehicle equipment workshop: In the past, foreign experts told us how to repair, but the core technology did not tell us. Parts are also from foreign manufacturers, and no questions are answered. Now they are all independent and localized, and any problems will be solved as soon as they are communicated. The maintenance methods are more advanced, and the equipment and technology are also world-leading. I'm really happy. This kind of work intensity will run through Spring Festival travel rush, but for Ren and his workers, it is their greatest pride that every EMU train can start safely and on time.
