The invention provides a train braking system state detection method and device. The method comprises the steps of acquiring longitudinal relative displacement information between a wheel set of a train bogie and a train body; according to the longitudinal relative displacement information, determining a residual error of a standard braking force of a current braking mode of the train, wherein the standard braking force is the braking force when a braking system corresponding to the braking mode works normally; determining the state of the braking system of the train according to the residual error of the standard braking force of the current braking mode of the train and the classification threshold value of the braking system of the train; and reporting fault information when the brake system of the train is in a fault state. Through the above mode, due to a fact that the longitudinal relative displacement information between the wheel set of the train bogie and the train body is directly related to the braking force of the braking system, the accuracy of braking fault detection is improved.

    本发明提供一种列车制动系统的状态检测方法及装置,方法包括:获取列车转向架的轮对和列车车体之间的纵向相对位移信息;根据纵向相对位移信息,确定列车当前制动模式的标准制动力的残差,标准制动力为制动模式对应的制动系统正常工作时的制动力;根据列车当前制动模式的标准制动力的残差和列车的制动系统的分类阈值,确定列车的制动系统的状态;在列车的制动系统处于故障状态时上报故障信息。通过上述方式,由于列车转向架的轮对和列车车体之间的纵向相对位移信息与制动系统的制动力直接相关,提高了制动故障检测的准确率。
