The invention provides a train emergency braking control circuit and method. The train emergency braking control circuit comprises an execution loop and a control loop which are associated through an electromagnetic switch, wherein a coil component of the electromagnetic switch is arranged in the control loop, and a contact of the electromagnetic switch is arranged in the execution loop; and the control loop is provided with an emergency braking trigger component, the execution loop is provided with an emergency braking electromagnetic valve serving as a load, and in the normal operation state, the emergency braking trigger component is disconnected, the coil component of the electromagnetic switch loses power, a contact of the electromagnetic switch is disconnected, the execution loop and the control loop are disconnected, and emergency braking is executed. In the scheme, the condition for triggering the emergency braking is separated from the execution loop, so that the emergency braking triggering component on the control loop is not influenced by the load current on the execution loop when triggering the emergency braking, and the purposes of reducing the influence of the load current on the emergency braking and improving the emergency braking control reliability are achieved.
本发明提供一种列车紧急制动控制电路及方法,该列车紧急制动控制电路包括通过电磁式开关关联的执行回路和控制回路;电磁式开关的线圈部件设置于控制回路,电磁式开关的触点设置于执行回路;控制回路上设置有紧急制动触发部件,执行回路上设置有作为负载的紧急制动电磁阀,当正常运行状态时,紧急制动触发部件断开,电磁式开关的线圈部件失电,电磁式开关的触点断开,使执行回路和控制回路断开,执行紧急制动。在本方案中,将触发紧急制动的条件和执行回路分离,使控制回路上的紧急制动触发部件触发紧急制动时,不受执行回路上的负载电流的影响,实现降低负载电流对紧急制动的影响,提高紧急制动控制可靠性的目的。
