The invention discloses a locomotive and a fault detection and redundancy control system and method for a brake cylinder of a brake of the locomotive; the method comprises the steps: judging whether an air distribution valve breaks down or not through the pressure of an acting pipe in a release state, and switching off the air distribution valve by controlling a switching electromagnetic valve to be electrified when the air distribution valve breaks down; controlling the pressure of the brake cylinder pre-control air cylinder by the fault-free electronic distribution valve, so that the locomotive can normally generate a relieving effect, the redundancy control of the pressure of the brake cylinder pre-control air cylinder in a relieving state when the air distribution valve fails is realized, and the risk of locomotive driving safety caused by the failure of the air distribution valve is reduced, and therefore, running reliability and safety of the locomotive are ensured. According to the system and the method, original hardware devices in the brake are utilized, and on-line judgment of the brake cylinder pre-control air cylinder fault and redundancy control functions during the fault are realized by changing the control flow of the brake control unit under the condition that a hardware structure is not added.

    本发明公开了一种机车及其制动机制动缸故障检测与冗余控制系统、方法,在缓解状态时,通过作用管压力判断空气分配阀是否存在故障,且在空气分配阀存在故障时通过控制转换电磁阀得电来隔断空气分配阀,并由无故障的电子分配阀控制制动缸预控风缸压力,使机车能够正常产生缓解作用,实现了缓解状态且空气分配阀故障时制动缸预控风缸压力的冗余控制,降低了因空气分配阀故障造成机车行车安全的风险,保证了机车行车的可靠性和安全性。本发明所述系统及方法利用制动机内部原有硬件装置,在不增加硬件结构的情况下,通过改变制动控制单元的控制流程,实现了制动缸预控风缸故障的在线判断以及故障时的冗余控制功能。
