The invention discloses a rail transit vehicle smoke and fire alarm control method and a vehicle, and the method comprises the steps: judging whether a smoke and fire alarm signal is detected or not,if yes, controlling a train to apply traction blocking and auxiliary blocking after a train network control system receives the smoke and fire alarm signal, and cutting off a main power supply loop. According to the invention, a high-voltage circuit (a main power supply loop) can be cut off at the first time when a fire occurs, so that an electric fire secondary fault is avoided; the smoke and fire alarm signal is combined with the train traction control logic, so that the protective action of the train control system is realized when the train has a smoke and fire alarm fault.
本发明公开了一种轨道交通车辆烟火报警控制方法及车辆,判断是否检测到烟火报警信号,若是,则列车网络控制系统接收到烟火报警信号后,控制列车施加牵引封锁和辅助封锁,并切断主供电回路。本发明可以在发生火灾的同时如何第一时间实施保护,切断高压电路(主供电回路),避免发生电火次生故障;将烟火报警信号与列车牵引控制逻辑联合,实现了列车在发生烟火报警故障时,列车控制系统的保护性动作。
