The embodiment of the invention provides a rail vehicle emergency braking control circuit and a working method thereof, and the circuit comprises a one-bit end activation relay, a two-bit end activation relay, a vehicle non-braking heavy fault relay, a whole vehicle non-braking heavy fault relay, a forward diode and a backward diode, if the brake valve in the single compartment sends out a brake heavy fault signal, the vehicle non-brake heavy fault relay of the corresponding compartment is powered off, the whole vehicle non-brake heavy fault relay is powered on, and the vehicle runs normally; if the brake valves in the multiple carriages send out brake heavy fault signals, the vehicle non-brake heavy fault relay of the corresponding carriage loses power, the whole vehicle non-brake heavy fault relay loses power, and the vehicle is triggered to be braked emergently. In this way, a more reliable railway vehicle brake heavy fault circuit can be established, so that the vehicle can obtain a whole vehicle brake heavy fault signal in time.

    本公开的实施例提供了一种轨道车辆紧急制动控制电路及其工作方法,该电路包括:一位端激活继电器、二位端激活继电器、本车无制动重故障继电器、整车无制动重故障继电器、正向二极管及反向二极管,若单节车厢中的制动阀发出制动重故障信号,则对应车厢的本车无制动重故障继电器失电,整车无制动重故障继电器得电,车辆正常运行;若多节车厢中的制动阀发出制动重故障信号,则对应车厢的本车无制动重故障继电器失电,整车无制动重故障继电器失电,触发车辆紧急制动。以此方式,可以建立更可靠的轨道车辆制动重故障电路,使得车辆可以及时获取整车制动重故障信号。
