According to the train emergency braking system and the control method, after compressed air supplied to an air cylinder enters the emergency braking system through a UB air path connector, a pressure regulating valve is firstly arranged to depressurize UB compressed air, and the pressure of the UB compressed air is reduced to a proper pressure value P1; the decompressed compressed air is divided into two paths through a three-way connector, one path is sequentially provided with a high-speed inflation electromagnetic valve, a high-speed exhaust electromagnetic valve, a pressure sensor and a test connector, and the high-speed inflation electromagnetic valve and the high-speed exhaust electromagnetic valve are high-speed switch electromagnetic valves; and the other path is provided with another pressure reducing valve, so that the gas pressure of the pipeline is reduced to the minimum emergency braking guarantee pressure P2. The problem that in the prior art, the optimal emergency braking pressure cannot be obtained in real time according to the existing train operation environment and the existing train conditions is solved, the risks of wheel rubbing and insufficient braking force are reduced, and the technical problem that the braking distance exceeds the standard is solved.

    本发明公开了一种列车紧急制动系统及控制方法,供给风缸压缩空气通过UB气路接口进入紧急制动系统内后,先设置调压阀对UB压缩空气进行减压,将其压力降至合适压力值P1;接着通过三通接头将减压后的压缩空气分成两路,其中一路依次设置高速充气电磁阀、高速排气电磁阀、压力传感器和测试接头,高速充气电磁阀和高速排气电磁阀均为高速开关电磁阀;另一路设置另一减压阀,将管路气体压力降为紧急制动最低保证压力P2。本发明解决了现有技术中列车紧急制动压力无法根据现车运营环境和现车自身条件实时取得最优紧急制动压力的问题,降低了擦轮和制动力不足的风险,避免制动距离超标的技术问题。
