------------------------
Rest at home today. . . Lying on the bed and flipping through the phone album. . I found some photos of the China Railway Train Dispatching System I taken before.
I chose some photos to share, and I will add some instructions to let you understand how China's high-speed rail/normal trains are controlled and running.
-------------------------
In China, all railways and trains are operated by 18 railway groups, which are managed by the "China National Railway Group Co., Ltd." and are headquartered in Beijing.
The photo below is one of the 18 railway groups I took: Zhengzhou Railway Group Dispatching Center.
------------------------
Zhengzhou Railway Group, in front of the Dispatching Building.
----------------------
An aerial photo of Zhengzhou North Cargo Marshalling Station in 2019. This is the largest freight marshalling station in Asia and one of the departure points of China-Europe trains.
-------------------------
This photo was taken when I was standing on the seventh floor of the railway dispatching center building.
In the photo, you can see a freight train of the China-Europe Express, the middle one with CR containers.
(Zhengzhou, China - Hamburg, Germany, twice a week. Train number X8001 (OLD: 80001). The whole journey is 10245 kilometers, Zhengzhou, China - Kazakhstan - Russia - Belarus - Poland - Hamburg, Germany)
----------------------------
The outer corridor of the IC card data processing department of Zhengzhou North Dispatching Center.
On the wall are oil paintings of railway locomotives painted by the railway staff themselves. Great work of art~
Here, I reveal a data. The total number of employees of the Zhengzhou Railway Group, which was established on March 11, 1949, has now exceeded 90,000.
This is an oil painting by another railway locomotive maintenance worker on the outer wall of the building. . The picture was a little paler, eroded by wind and rain. . .
---------------------------------
Regarding the IC card data center just now, what is an IC card?
It is the data storage card of ordinary locomotive in China, which is inserted into the locomotive LKJ system to run. The card records the driver information, locomotive information, running path, section speed limit, stop stations and other data.
After the driver gets off work, this IC card will be returned to the data center, and the computer will automatically analyze the operating record data of the driver and the locomotive, and analyze and judge the operation of the driver.
I made a screen description of LKJ2000 for everyone in English,
In fact, all ordinary internal combustion/electric locomotives in the world have similar operation and control ideas. . . . Now that the computer is fully controlled, basically you put the speed control handle in the corresponding position, and the train computer will automatically adjust the speed for you and run it according to the speed limit and slope of the line.
Of course, it's the same as a car. . Each locomotive / EMU has a key to start the engine. .
A small extension:
At present, the driver's anti-drowsy device is added to China's high-speed rail/ordinary railway trains. The driver of high-speed rail trains needs to step on the anti-drowsy pedal every 30 seconds. If not stepped on for more than 30 seconds, the LKJ and ATP systems will issue an alarm. After 1 minute, the train will automatically brake and stop.
Of course, curious friends should not try to drive a train secretly. I don't want to see you in the international news. . .
--------------------------------
This is the control and dispatch center of the train.
The lines on the big screen are the train running diagrams.
Each line represents the operating range of a train, stopping at the station, and stopping time.
-----------------------------------
The chair on my left is the position of the director of the entire control center. Each console is a unit.
Everything is automated, and the train's location will be displayed on the dispatch center screen through the 5G/GSM/Beidou navigation system.
The black background on the big screen is Zhengzhou Passenger Station, the thick red line represents the current position of the passenger train currently stopping at the station, the train number in the middle, and the two curved white lines represent the two passenger trains running path, all railway signals and railway switch control are completed by computer automation. Each side of Zhengzhou Station can allow 4 passenger trains to enter/exit at the same time.
------------------------------
Look closely at the big screen with a black background,
The white line on the left represents that the C2876 intercity train is about to leave the station. The white lines represent the turnouts and running paths that C2876 will pass. The green dot indicates the green light signal, allowing C2876 to start. This train should be an intercity train using CRH6 EMU, which runs on the Zhengzhou-Jiaozuo intercity railway.
The right side also consists of a white line and a white dot. This is an electric locomotive. It is going to the station to tow passenger trains T198.
A little popular science:
In China, there is usually a shunting signal in front of the turnout. The signal is composed of two lights, a blue light and a white light. . This is a shunting signal machine. The white light means that the driver is allowed to drive the locomotive through the turnout behind the current signal, and the blue light means that it is forbidden to pass.
The white dot on the screen just now indicates that the turnout signal has been turned on, allowing the driver to drive the electric locomotive through the turnout to the next location.
-------------------------
The console composed of these four screens is the high-speed rail dispatching console.
Yes, it is this console, only one person is needed. The computer automatically controls the entry and exit routes and signals of more than 300 high-speed EMUs that day.
The dispatcher only needs to check the information of the high-speed train in front of the computer, and then adjust or input the departure/arrival time of the high-speed train, train number, vehicle formation and other information on the computer. All the rest is handed over to the data server downstairs for automatic analysis and processing.
Technology has really changed everything.
-------------------------
This is the video monitoring room for railway operation.
Here, the entire railway locomotive depot/marshalling station system and the safe operation of the railway will be monitored.
When a railway accident occurs, the monitoring room can directly send railway rescue trains or related rescue personnel to the scene, and directly view and direct the scene rescue work through the 5G system.
Similar to the fire department of an airport.
-------------------------
This is the railway operation video analysis department.
Each train is equipped with a 6A video surveillance system, which records the operating status of a locomotive's driver's cab, locomotive equipment room, locomotive front, side, top pantograph, bogie, and vehicle transmission system. Similar to a driving recorder.
Through the video, you can intuitively check the running status of a locomotive and whether the driver's operation process meets the requirements. When a train fails during operation, technicians can directly see the operation of the failed train through the video, and directly guide the driver to solve the current problems through the 5G video connection. This is part of the safe operation of the railway.
