The invention provides a train operation state diagnosis method and device and a rail transit sensing system, and the method comprises the steps: obtaining a target electric signal, and drawing a first curve according to the target electric signal; carrying out peak value identification according to the first curve to determine a target first curve, and determining the running state of the train in a first duration corresponding to the target first curve as a starting state; drawing a second curve according to the first curve, wherein the second curve is a curve that the current frequency changes along with time in the preset time period; and according to the second curve, peak value identification is carried out to determine a target second curve, and the running state of the train in a second duration corresponding to the target second curve is determined as a braking state. The method solves the problem that a potential-based rail train running state monitoring method is lacked in the prior art.

    本申请提供了一种列车运行状态的诊断方法、装置和轨道交通感知系统,该方法包括:获取目标电信号,并根据所述目标电信号绘制第一曲线;根据所述第一曲线进行峰值识别确定目标第一曲线并将所述目标第一曲线对应的第一时长内列车的运行状态确定为启动状态;根据所述第一曲线绘制第二曲线,所述第二曲线为所述预设时间段内电流频率随时间变化的曲线;根据所述第二曲线进行峰值识别确定目标第二曲线并将所述目标第二曲线对应的第二时长内列车的运行状态确定为刹车状态。该方法解决了现有技术中缺乏一种基于电势的轨道列车的运行状态的监测方法的问题。
