[0035] Furthermore, the laser protection fence 22 in the maintenance depot and the maintenance depot data acquisition control are connected to the broadcast base station 6.

[0036] By those skilled in the art, the components in this case are connected and assembled in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.

[0037] Embodiment: When in use, a turnout sensor 16 and a turnout approach LED display screen 17 are installed on each turnout, the turnout sensor signal 16 is connected to the data acquisition wireless transmission base station 5, and the turnout direction information is transmitted to the locomotive and the ground terminal through the data acquisition wireless transmission base station 5 to form a visual view. The locomotive driver and the dispatcher can view the track opening status in real time according to the program interface, and the switchman can clearly confirm the turnout direction through the turnout approach LED display screen 17.

[0038] A derailer sensor 15 is installed on each derailer and connected to a data acquisition wireless transmission base station 5. The insertion and removal status of the derailer is transmitted to the locomotive and ground terminal program through the data acquisition wireless transmission base station 5 to form a visual view. The locomotive driver and dispatcher can view the insertion and removal status of the derailer in real time according to the program interface.

[0039] A wireless beacon 19 is installed at a certain distance on each track sleeper. Each wireless beacon 19 is set with a unique ID code. When a locomotive passes by, the wireless beacon 19 transmits an ID code signal, which is received and processed by the antenna of the shunting operation safety auxiliary system host 1 and displayed graphically on the on-board display screen. The locomotive position information is also transmitted to the dispatching computer through wireless and network channels, and is processed by the dispatching software and displayed on the dispatching display screen.

[0040] The shunting operation safety auxiliary system host 1 is connected to the locomotive speed sensor, and the locomotive speed signal is processed by software and displayed on the screen in real time. When the speed exceeds the limit value, the shunting operation safety auxiliary system host 1 controls the locomotive to lose power, and restores power when the speed is lower than the limit value.

[0041] By installing wireless beacons 19 on the sleepers in the restricted and prohibited sections of the shunting locomotive, when the shunting locomotive enters the section and identifies the early warning wireless beacon 19, the system will first broadcast an early warning voice. If the shunting locomotive driver does not take braking measures, the vehicle will continue to move. When the shunting locomotive identifies the braking wireless beacon 19, the locomotive will take emergency braking and exhaust to prevent the locomotive from advancing recklessly.

[0042] A turnout sensor 16 is installed before and after the turnout. When the track that the shunting locomotive enters does not match the track it should enter, the system automatically makes a voice announcement and applies exhaust brake.

[0043] A wheel sensor is installed 20 meters in front of the fixed derailer on the shunting line. The wheel sensor is connected to the data acquisition wireless transmission base station 5. The derailer in front of the train in the direction of travel is in the up and off state. When the two wheels of the train press on the wheel sensor at the same time, the data acquisition wireless transmission base station 5 issues an emergency stop command, which is transmitted to the locomotive equipment through the wireless data transmission channel to start the emergency exhaust stop.

[0044] A wheel sensor is installed 10 meters in front of the earth barrier at the end of the pipeline and connected to the data acquisition wireless transmission base station 5. When the two wheels of the train press on the wheel sensor at the same time, the data acquisition wireless transmission base station 5 issues a command, which is transmitted to the shunting operation safety auxiliary system host 1 through the wireless data transmission channel to control the locomotive to emergency exhaust and stop.

[0045] The voice and light warning function for shunting in the maintenance depot is achieved by setting the warning light on the ground. During shunting in the depot, the warning light is red. When shunting is completed and vehicle maintenance work is carried out, the light is converted to white auxiliary lighting, and voice safety reminders are broadcast in the depot at the same time.

[0046] A derailer insertion and removal status display screen is installed on the upper part of the maintenance depot door to display the derailer insertion and removal status synchronously with the fixed derailer. The derailer signal is connected to the LED display screen through the maintenance depot data acquisition control and broadcast base station to realize the real-time display of the derailer insertion and removal status in the maintenance depot.

[0047] Laser protection fences are installed on both sides of the track in the maintenance depot. When people or objects invade the line, data collection control and broadcast base station voice broadcast prompts are activated.

[0048] By installing surveillance cameras on the front, rear, left and right sides of the locomotive, the locomotive driver and co-driver can view the locomotive's surrounding environment in real time during shunting, eliminating visual blind spots and improving operational safety prevention capabilities.

[0049] A server is set up in the dispatching and control center, which is connected to the data acquisition and transmission base station through the network and stores the shunting operation process information through special management software. Managers at all levels can retrieve data such as track route display, turnout action, derailer insertion and removal records of the on-site shunting machine, switchman, and shunter operation process within the same day, week or month through the network, which is convenient for analyzing and spot checking the problems of on-site operators.
