The invention relates to a train emergency braking system and a train emergency braking control method.The control method comprises the following steps that after the system is started, whether a train has an emergency braking instruction or not is judged; if the train has the emergency braking instruction, an emergency braking valve control channel is controlled to be opened to implement emergency braking; detecting whether a brake cylinder pressure sensor fails or not in real time; if the brake cylinder pressure sensor breaks down, whether emergency braking is effective or not is judged according to the deceleration of the train; if the brake cylinder pressure sensor has no fault, judging whether emergency braking is effective or not according to brake cylinder pressure; and when the emergency braking fault occurs, the proportional valve is controlled to charge oil into the brake cylinder for braking compensation. The technical problems that in the prior art, due to train emergency braking loop faults, braking force is insufficient, and the braking distance exceeds the standard are solved.
本发明涉及一种列车紧急制动系统及列车紧急制动控制方法,控制方法包括如下步骤:系统启动后,判断列车是否有紧急制动指令;若列车有紧急制动指令,控制紧急制动阀控制通路打开实施紧急制动;实时检测制动缸压力传感器是否有故障;若制动缸压力传感器有故障,根据列车的减速度大小判断紧急制动是否有效;若制动缸压力传感器无故障,根据制动缸压力判断紧急制动是否有效;当紧急制动故障时,控制比例阀向制动缸充油进行制动补偿。本发明解决了现有技术中列车紧急制动回路故障导致制动力不足、制动距离超标的技术问题。
