1. A train integrity detection system based on Beidou short message communication, comprising:
a vehicle-mounted Automatic Train Protection (ATP) host, and
a train rear device and a ground Radio Block Center (RBC) device,
wherein the vehicle-mounted ATP host communicates with both the train rear device and the ground RBC device, the vehicle-mounted ATP host and the train rear device each comprises a main control unit, a wind pressure detection module, a wireless communication module, and a speed measurement module and a satellite positioning module which are connected with the main control unit, and the vehicle-mounted ATP host and the train rear device also each comprises a Beidou short message communication module connected with the main control unit,
wherein the Beidou short message module is added to the train rear device, which is used to realize train rear information transmission and position acquisition when two fault points, that is, the wireless communication module and the satellite positioning module, fail.
