Locomotive brake control system and control method

The invention provides a locomotive brake control system and control method. The system comprises an average pipe control module, a brake cylinder control module and a main air conditioner. When an air charging and discharging electromagnetic valve or a second relay valve for controlling the brake cylinder breaks down, multiple redundancy of a mechanical three-way valve, average pipe pressure, an emergency pressure increasing valve and the like can be used, and redundancy control over the pressure of the brake cylinder is achieved. 本申请提供了一种机车制动控制系统及控制方法，该系统包括平均管控制模块、制动缸控制模块和总风；当控制制动缸的充排气电磁阀或第二中继阀故障时，可以使用机械三通阀、平均管压力、紧急增压阀等多重冗余，实现对制动缸压力的冗余控制。
