[0002] Wireless communication locomotive radios are widely used in local railway traffic dispatching and command systems for wireless communication between locomotives and ground equipment. Local railways are mostly built in mining areas and rural areas. There are many crossings along the railway, including unmanned crossings and manned crossings. When there is an abnormal situation at a manned crossing, the crossing attendant cannot obtain the phone number of the approaching locomotive in time. It is necessary to call the station landline to contact the station attendant, and then the station attendant will call the locomotive driver for an early warning. At unmanned crossings, the crossing safety officer can only remotely monitor the crossing situation through a camera. When there is an abnormality, he will contact the station attendant, and then contact the driver through the station attendant. There are many transfer links and the time is extended, which seriously affects driving safety. Summary of the invention

[0036] 2) Railway wireless track locomotive communication, realizing video calls between locomotive and crossing stations through LTE network.

[0037] 3) Automatic joint control of the track and machine. When the locomotive station approaches the crossing station, it automatically sends a protection reminder message to the crossing station.

The server sends the location information and telephone contact information of the crossing platform or station platform ahead to the locomotive platform. The CPU core board calculates the distance between the locomotive platform and the crossing platform, and automatically sends a protection prompt message to the crossing ahead when approaching.

[0043] When there is an unmanned crossing ahead, the driver can make a judgment based on the real-time crossing video displayed on the locomotive platform. When the AI ​​server finds that there are people, vehicles or other objects crossing the crossing at an unmanned crossing, it will also send an early warning message to the locomotive platform to prompt the locomotive driver to slow down and avoid it.
