The invention discloses a system safety protection method applicable to train integrity loss of a CBTC (Communication Based Train Control) system, which overcomes the defects in the prior art and comprises the following steps that: a train-mounted ATP (Automatic Train Protection) of a train is periodically positioned and continuously reports the position of the train to a trackside ATP, and the trackside ATP acquires activation information of all special protection areas in a jurisdiction range in real time and sends the activation information to the train-mounted ATP of the train; the train-mounted ATP of the train checks the integrity of the train, and if the integrity of the train is lost, the train-mounted ATP reports an integrity loss alarm to the trackside ATP; the trackside ATP activates the special protection area of the possible position of the train according to the integrity loss alarm, and then informs other trains in the jurisdiction that the special protection area is activated; and vehicle-mounted ATP positioning of other trains in the jurisdiction area checks whether the train position is in the activated special protection area or not, and if the train position is in the activated special protection area, the other trains apply emergency braking to stop.

    本发明公开了一种适用CBTC系统的列车完整性丢失的系统安全防护方法,解决了现有技术的不足,包括:列车的车载ATP周期性定位并持续向轨旁ATP汇报列车位置,轨旁ATP实时获取管辖范围内所有的特殊保护区域的激活信息并发送至列车的车载ATP;列车的车载ATP检查列车的完整性,若列车的完整性丢失,则车载ATP向轨旁ATP上报完整性丢失报警;轨旁ATP根据完整性丢失报警激活列车可能所在位置的特殊保护区域,然后告知管辖范围内的其他列车特殊保护区域已激活;管辖范围内的其他列车的车载ATP定位检查列车位置是否处于激活的特殊保护区域,若在激活的特殊保护区域,则其他列车施加紧急制动停车。
