The invention relates to a safe communication positioning method and device for a rigid train body, and the method comprises the steps: carrying out the periodic positioning through a vehicle-mounted communication positioning terminal and a built-in electronic map of a train, and obtaining the positioning information of the vehicle-mounted communication positioning terminal; according to the positioning information of the vehicle-mounted communication positioning terminal, self-inspection and mutual correction of the vehicle-mounted communication positioning terminal are carried out; if the self-checking and the mutual checking are both passed, radar positioning is used as train positioning output, and if the self-checking and the mutual checking are not passed, a train operation total system enters a safety mode, and a bypass system is restarted. Compared with the prior art, the vehicle-mounted communication positioning terminal has the advantages that the safety guarantee of the positioning function is realized through self-inspection and mutual correction between the vehicle-mounted communication positioning terminals, and the principle of a 2oo2 combination fault safety architecture is met.

    本发明涉及一种针对刚性列车车体的安全通信定位方法及设备,所述方法包括:利用车载通信定位终端与列车内置电子地图进行周期性定位,得到车载通信定位终端定位信息;根据车载通信定位终端定位信息,进行车载通信定位终端的自检和互校;若自检和互校皆通过,则将雷达定位作为列车定位输出,若自检和互校未通过,则使列车运行总系统进入安全模式并重启旁路系统。与现有技术相比,本发明通过车载通信定位终端之间进行自检和互校,实现定位功能的安全保障,符合2oo2组合故障安全架构的原理。
