The embodiment of the invention provides a railway vehicle fire alarm control circuit, a safety loop system and a railway vehicle, when a first network is normal, a fire alarm test signal is output to a fire alarm controller, and the fire alarm controller performs a fire alarm test according to the fire alarm test signal; when the test result of the fire alarm test circuit is normal and the second network is normal, a fire alarm starting circuit is started, the fire alarm starting circuit comprises a second network module and a fire alarm control relay, when the fire alarm starting circuit is started, a normally open contact of the fire alarm control relay is closed, and a self-locking contact of the fire alarm relay is electrified and self-locked; therefore, testing and starting before fire monitoring are completed, preparation is made for a follow-up fire alarm system to enter a working state, meanwhile, when a fault occurs in the fire alarm system test, the fault condition can be known in time, system starting can be restrained in time, influences on other systems affected by fire alarm signals are reduced, the safety coefficient of a railway vehicle is increased, and the safety coefficient of the railway vehicle is increased. And safe operation of the train is guaranteed.

    本申请实施例中提供了一种轨道车辆火警控制电路、安全环路系统及轨道车辆,当第一网络正常时向火警控制器输出火警测试信号,火警控制器根据火警测试信号进行火警测试;当火警测试电路的测试结果正常且第二网络正常时启动火警启动电路,火警启动电路包括第二网络模块和火警控制继电器,当火警启动电路启动时,火警控制继电器的常开触点闭合,火警报警继电器的自锁触点得电自锁;由此以完成火灾监测前的测试及启动,为后续火警系统进入工作状态做准备,同时当火警系统测试出现故障时能够及时得知故障情况,并能够及时抑制系统启动,减少对受火警信号影响的其他系统的影响,提高轨道车辆安全系数,为列车安全运行提供保障。
