The invention relates to a locomotive brake cylinder sensor drift fault detection and control system and a train. The action pipe is used for controlling the brake cylinder to inflate or deflate; the action pipe pressure detection device is used for detecting the pressure of the action pipe; the first pressure detection device is used for detecting the pressure of a brake cylinder; the second pressure detection device is arranged on a same pressure pipeline with the first pressure detection device; the two pressure detection devices are used for detecting the pressure of the brake cylinder to judge whether drifting occurs or not, the pressure of the action pipe is introduced to determine the drifting pressure detection device so as to correct the detection value of the drifting pressure detection device, and the actual pressure value, detected by the normal pressure detection device, of the brake cylinder is used for controlling and displaying a locomotive. The situation that the locomotive cannot run due to traction blocking caused by sensor drifting is avoided.
本发明涉及一种机车制动缸传感器漂移故障检测及控制系统及列车,包括:制动缸;控制制动缸充气或排气的作用管;用于检测作用管压力的作用管压力检测装置;用于检测制动缸压力的第一压力检测装置以及设置在与第一压力检测装置同压力管路上的第二压力检测装置;通过两个压力检测装置检测制动缸压力以判断是否发生漂移,并引入作用管压力以确定所发生漂移的压力检测装置进而修正其检测值,将判断为正常的压力检测装置所检测到的制动缸实际压力值用于机车的控制和显示,避免了传感器漂移引起牵引封锁导致机车无法运行的情况。
