The invention relates to the technical field of rail transit, in particular to a fault detection method and device and a rail vehicle. The method comprises the following steps: acquiring one or more parts of fault data sent by equipment to be tested through a first communication network and/or a second communication network in a double-loop network; wherein the equipment to be tested corresponds to one or more controllers, and each controller sends fault data through the first communication network and/or the second communication network; determining a communication state between each controller and the first communication network and/or the second communication network based on the life signal in each fault data; determining target fault data in the one or more parts of fault data based on the communication state of each controller with the first communication network and/or the second communication network and the number of the controllers corresponding to the to-be-tested equipment; the target fault data is used for performing fault detection on the to-be-detected equipment. According to the invention, the accuracy and reliability of a fault detection result can be effectively improved, so that the running safety of the vehicle is effectively improved.

    本发明涉及轨道交通技术领域,尤其涉及一种故障检测方法、装置及轨道车辆。其方法包括:获取待测设备通过双环网中的第一通讯网络和/或第二通讯网络发送的一份或多份故障数据;其中,待测设备对应有一个或多个控制器,每个控制器通过第一通讯网络和/或第二通讯网络发送故障数据;基于各故障数据中的生命信号,确定各控制器与第一通讯网络和/或第二通讯网络的通讯状态;基于各控制器与第一通讯网络和/或第二通讯网络的通讯状态,以及待测设备对应的控制器的数量,确定一份或多份故障数据中的目标故障数据;目标故障数据用于对待测设备进行故障检测。本发明能够有效提高故障检测结果的准确性和可靠性,从而实现了车辆运行安全性的有效提高。
