The invention discloses a locomotive fault detection method, system and device and a locomotive, and is applied to the field of detection. When the traction force of the locomotive meets the locomotive starting condition, judging whether the state of the locomotive is a static state or not; if the state of the locomotive is a static state, judging that a transmission shaft of the locomotive has a fault; if the state of the locomotive is not the static state, judging whether the acceleration time for the locomotive to reach the preset speed is greater than the preset time or not; and if the time is longer than the preset time, judging that the transmission shaft of the locomotive has a fault. Judging whether the transmission shaft breaks down or not according to the state and traction force of the locomotive in the locomotive starting stage. When the locomotive is in a running state, whether the transmission shaft breaks down or not is judged through the locomotive speed and acceleration time, and the calculation mode is simple. Meanwhile, the acquisition mode of the traction force, the speed and other parameters is simple and convenient.

    本发明公开了一种机车故障的检测方法、系统、装置及机车,应用于检测领域。当机车的牵引力满足机车启动条件时,判断所述机车的状态是否为静止状态;若所述机车的状态为静止状态,则判定所述机车的传动轴出现故障;若所述机车的状态不为静止状态,则判断所述机车达到预设速度的加速时间是否大于预设时间;若大于所述预设时间,则判定所述机车的传动轴出现故障。在机车启动阶段通过机车的状态及牵引力判断传动轴是否出现故障。在机车运行状态时,通过机车速度及加速时间判断传动轴是否出现故障,计算方式比较简单。同时,牵引力和速度等参数的获取方式较为简便。
