The invention discloses a railway wagon brake natural mitigation troubleshooting method and device, and the method comprises the steps: carrying out the air charging of a train pipe, an auxiliary air cylinder and a buffer air cylinder of a railway wagon brake to a first pressure through a single vehicle tester or a locomotive brake, reducing the pressure of the train pipe to a second pressure after the pressure is stabilized, and maintaining the pressure; after the pressure of the train pipe is stable, the pressure values of the train pipe, the auxiliary air cylinder, the buffering air cylinder and the brake cylinder are read for the first time through a pressure sensor; after waiting for a period of time, when the railway wagon brake has a natural relief fault, namely the pressure of the brake cylinder suddenly drops, reading the pressure values of the train pipe, the auxiliary air cylinder, the buffer air cylinder and the brake cylinder for the second time through a pressure sensor; and on the basis of the change conditions of the pressure values of the train pipe, the auxiliary air cylinder, the buffer air cylinder and the brake cylinder which are read twice, the natural fault relieving reason of the railway wagon brake is judged through a pressure difference troubleshooting method or a curve slope troubleshooting method. According to the invention, rapid troubleshooting of natural remission faults is realized.

    本发明公开了一种铁路货车制动机自然缓解故障排查方法及装置,其中方法包括:通过单车试验器或机车制动机对铁路货车制动机的列车管、副风缸和加缓风缸充风至第一压力,待稳定后将列车管压力减压至第二压力后进行保压;待列车管压力稳定后,通过压力传感器第一次读取列车管、副风缸、加缓风缸和制动缸的压力值;等待一段时间后,待铁路货车制动机发生自然缓解故障即制动缸压力突然下降时,通过压力传感器第二次读取列车管、副风缸、加缓风缸和制动缸的压力值;基于前后两次读取的列车管、副风缸、加缓风缸和制动缸的压力值变化情况,通过压差排查法或曲线斜率排查法判断铁路货车制动机自然缓解故障原因。本发明实现了自然缓解故障的快速排查。
