Meanwhile, the communication service platform processes the high-precision position of the rail car returned by the vehicle-mounted equipment in the station, and determines the track information occupied by the rail car through the electronic map. In addition, the shunting operation protection service platform receives the TDCS shared information of the road bureau, and finally sends the station track running position information, the position coordinate information, the TDCS information and the like of the corresponding rail cars in each station yard to the GMS platform. And the GMS platform repackages and encrypts the related data information and transmits the data information to the GMS equipment through a wireless network.

Wherein, the station site electronic map: the information acquisition of station track sections, signal machines, turnouts and various prevention and control points (fixed derailers, no-parking areas, contact net terminals, car stops, station boundaries and the like) is completed by using a high-precision mapping technology and a manual supplementary measurement means, and longitude and latitude coordinate data corresponding to the mapping points are compiled into corresponding station high-precision electronic maps.
Vehicle-mounted host computer: the host computer adopts a 3U standard case structure and is in modular design. The host plug-in sequence is: a power supply plug-in 8R, a digital plug-in 4R, an analog plug-in 4R, a main control plug-in 4R, a switching plug-in 8R, a positioning plug-in 4R and a standby plug-in 4R.

Compared with the prior art, the technical scheme has the advantages that:
1) the cost is saved; a differential base station is not required to be built on the ground, the high-precision positioning of the rail car is realized by using a satellite-based differential system, the positioning precision is high, and the cost is saved.
2) Collision avoidance and early warning; have point-to-point range finding anticollision function, carry out early warning suggestion and anticollision function to railcar, flatbed, soil fender, derailer. Have the signal machine anticollision early warning's that closes function on going into, prevent that the railcar from crossing the signal machine of closing.
Each rail car shunting operation protection vehicle-mounted device in the station collects high-precision positioning information, car number information, speed information and running direction information and sends the high-precision positioning information, the car number information, the speed information and the running direction information to the shunting operation protection service platform and the station electronic map registration mark, so that rail car station track occupation information and rail car running trend information are determined in real time.

Meanwhile, for fixed protection points such as a soil block and a derailer, the shunting operation protection vehicle-mounted equipment stores a station site electronic map, and when the running position coordinate of the rail car is close to the protection points, early warning is timely given out and braking protection is implemented. After the shunting operation protection vehicle-mounted equipment receives the TDCS information sent by the shunting operation protection service platform, according to the running position coordinate of the rail car and the position coordinate of the station signal machine, the anti-collision early warning of the closing signal machine in front of the approach is timely carried out, and the rail car is prevented from crossing the closed signal machine.
3) DMI route selection is convenient and fast; when the route is selected, the route curve is automatically generated only by clicking the starting point and the terminal of the route.
After the shunting operation protection service platform analyzes the TDCS information, the rail car route information is remotely issued through the railway special network and the mobile public network. Meanwhile, the driver compares the route information issued by the station attendant with the remotely issued route information, and the rear adjustable vehicle works in a consistent manner. When the shunting operation protection service platform cannot issue the rail car route information through the wireless network, a driver adopts a manual route selection mode to confirm the rear-side adjustable car operation without errors based on the route information issued by a station field attendant. Through the DMI display, a driver only needs to click an approach starting point signal machine and a terminal signal machine, an approach curve is automatically generated, and the method is convenient and fast. When multiple routes appear in the route selection, the driver can select the final shunting operation route by pressing the up and down keys
