The invention discloses a rail train head and tail positioning equipment redundancy and switching system and method, the system comprises positioning modules arranged at the head end and the tail end of a train and vehicle-mounted controllers, each vehicle-mounted controller is provided with an ATP and an ATO, and the vehicle-mounted controllers at the head end and the tail end of the train realize information interaction through an in-train communication network. The positioning module is provided with BTM positioning equipment and speed measuring equipment, and the BTM positioning equipment collects positioning beacon information beside a rail; the ATP and the ATO finish train positioning and periodic position updating according to the BTM positioning equipment and the speed measuring equipment at the home terminal respectively, the ATP continuously supervises and positions faults, and when the ATP at the head terminal judges that the positioning equipment at the home terminal fails, if the positioning equipment at the tail terminal is judged not to fail at the moment, the positioning information at the tail terminal is switched to be used for updating the position information at the home terminal. According to the method, train degradation and emergency braking caused by positioning loss can be avoided, and the operation efficiency is ensured.

    本发明公开了一种轨道列车头尾定位设备冗余及切换系统及方法,包括设于列车头尾两端的定位模块、车载控制器,车载控制器设有ATP和ATO,列车头尾两端的车载控制器之间通过车内通信网络实现信息交互,定位模块设有BTM定位设备以及测速设备,BTM定位设备采集轨旁的定位信标信息;ATP、ATO分别根据本端的BTM定位设备和测速设备完成列车定位以及周期位置更新,ATP持续监督定位故障,当头端ATP判断本端定位设备故障时,若此时判断尾端定位设备未故障,则切换使用尾端定位信息来更新本端位置信息。本发明可以避免由于失去定位导致的列车降级、紧急制动,保证了运营效率。
