Train integrity detection system based on Beidou short message communication

Abstract

The invention relates to a train integrity detection system based on Beidou short message communication. The system comprises a vehicle-mounted ATP host, train tail equipment and ground RBC equipment,and is characterized in that the vehicle-mounted ATP host is in communication connection with the train tail equipment and the ground RBC equipment respectively; the vehicle-mounted ATP host and thetrain tail equipment each comprise a main control unit, a wind pressure detection module, a wireless communication module, a speed measurement module and a satellite positioning module, wherein the wind pressure detection module, the wireless communication module, the speed measurement module and the satellite positioning module are connected with the main control unit; and the vehicle-mounted ATPhost and the train tail equipment each further comprise a Beidou short message communication module connected with the main control unit. Compared with the prior art, the system has the advantages ofhigh communication interference resistance, short response time and the like.

Description

technical field [0001] The invention relates to a train integrity detection system, in particular to a train integrity detection system based on Beidou short message communication. Background technique [0002] In the train control system, the train integrity monitoring plays an important role in ensuring the safety of the train. In order to prevent the decoupling and throwing of the train during the running process, it is necessary to use the tail device to check the integrity of the train. The end of train device is usually used in freight trains, which can realize the unattended rear of the train. By automatically collecting the wind pressure at the rear of the train, it is transmitted to the control box located in the cab to provide a basis for integrity judgment. [0003] After retrieval, Chinese Patent Publication No. CN107310591A discloses a train integrity detection method, device and system, the method comprising: obtaining train positioning data and train tail wi...
