The invention discloses a train fault diagnosis method and device and a train displayer, and the train fault diagnosis method comprises the steps that train operation data transmitted by all devices contained in a train control system are obtained in real time, a dynamic polling algorithm is applied to detect fault information in the train operation data, and a fault list is generated; receiving a fault diagnosis request of a user based on any fault information in the fault list; performing feature processing on the fault information in response to the fault diagnosis request, and drawing a fault curve; and according to the fault curve, using a preset diagnosis algorithm to carry out fault positioning, and obtaining a fault diagnosis result. According to the train fault diagnosis method, the actual running condition of the train is considered, the polling priority of each device in the current polling period is dynamically updated in combination with the change of the device state in each period, the load balancing and polling efficiency is improved, and the train fault diagnosis method has higher fault diagnosis efficiency.

    本申请公开了一种列车故障诊断方法、装置及列车显示器,列车故障诊断方法包括:实时获取列车控制系统包含的各设备传输的列车运行数据,并应用动态轮询算法检测所述列车运行数据中的故障信息,生成故障列表;接收用户基于所述故障列表中的任一故障信息的故障诊断请求;响应所述故障诊断请求,对所述故障信息进行特征处理,绘制故障曲线;根据所述故障曲线应用预设的诊断算法进行故障定位,获取故障诊断结果。本申请的列车故障诊断方法,考虑列车实际运行情况,结合每周期设备状态的变化,动态更新当前轮询周期各设备的轮询优先级,提升负载均衡和轮询效率,具有更高的故障诊断效率。
