　　There is a group of "invisible people" in the Huizhou Electric Department of Guangzhou Railway Group. They are inverted black and white, and they shuttle through the night at 4 or 5 in the morning day after day to confirm that the on-board equipment of the "Return to Hong Kong" EMU is operating normally.

On February 13, several "invisible people" were in the overhaul depot of Chaozhou EMU as usual, and started over 7 hours of overhaul work.

　　Chaozhou EMU is located in Fuyang Town, Chao'an District, Chaozhou City. Starting from Chaozhou Station, it bypasses several quiet rural roads and reaches the EMU after 8 kilometers.

The maintenance warehouse in the institute has 6 reconnected maintenance lines and 16 storage lines, which are responsible for the operational maintenance of 43 EMUs running on Meishan Passenger Dedicated Line and Xiamen-Shenzhen Line.

"This is the "harbour" of the EMU. The EMUs that have been running outside for a day have to come back here to rest every night!" said Li Zhao, the party branch secretary of the Chaozhou Train Control Vehicle Equipment Workshop.

　　At 0:35, a long train of blue and white trains is slowly entering the "harbour."

In an instant, no less than a hundred people gathered by the train.

Li Zhao said that every train returning here after a long-distance trip has to go through the coordination and cooperation of nearly 10 types of work from as many as 5 departments, including vehicles, maintenance, electricity, communications, and cleaning. A comprehensive "physical examination" and a thorough "cleaning" are carried out, and the on-board equipment work area is responsible for the inspection and maintenance of the lkj (train monitoring system) and atp (train overspeed protection system) that enter and exit the library. This is what everyone said with a smile A central system for the "brain doctor" of the high-speed train is a set of driving safety equipment for diagnosing whether the train is running over speed, monitoring the normal operation of the locomotive, and ensuring the operation of the high-speed train.

　　In addition to general overhaul and maintenance, each year before the Spring Festival Transport, the vehicle equipment workshop also conducts a comprehensive "physical examination" of the vehicle group under its jurisdiction. For each equipment inspection, the inspector must be named, and problems must be pursued. responsibility.

　　At 0:36, all preparations were ready. Foreman Liang Jian finished picking up the train and led two workers "fully armed" into the EMU.

Open the cabinet, check the appearance of the device, and tighten the screws.

When testing the equipment, watch, read, read, over and over again, carefully checking the menu and data on the display.

In front of the train operation recorder, the worker Li Xiaojie said, “This is the commonly known EMU'black box'. Every day, we download the recorded data of the'black box' on the warehousing EMU, and conduct a thorough analysis at the first time. The analysis of the data can discover the abnormal situation that occurred during the train operation!"

　　If two or three workers are working closely in a slightly crowded cab, then a small compartment less than 0.5 square meters behind the driver’s seat is extremely narrow and can barely turn around. “It’s vehicle equipment. The cable infiltrates into each "blood vessel" of the atp and lkj equipment, and is the main source of the'heart blood supply' of the EMU." said Li Xiaojie, who was lying on his waist and helping with the search light, "because the space is small, Each set of assignments for us has formed a big man and a small one, with a combination of thin and fat, otherwise it would be nothing like my body shape!"

　　After completing the inspection of the on-board equipment in the cab, I went to the bottom of the narrow locomotive to check the train signal receiving system installed in the locomotive's deflection part... After a busy period, the intercom again rang "No. 1101 EMU is in the warehouse and enters j6. 2 ranks, please prepare all departments for maintenance!" the call sound.

He immediately packed up his tools, ran all the way, and ran towards the direction of the oncoming car. At this time, Dongfang was already white.
