The embodiment of the invention provides an equipment redundancy method, an equipment redundancy device, a train network control system and a product. The train network control system comprises a plurality of functional equipment and at least two pieces of control equipment which are mutually redundant, any control device establishes communication connection with the function device through the first network or the second network; the method comprises the following steps: according to a preset time slot, detecting a master-slave state of each control device in a first network and a master-slave state of each control device in a second network in real time; and according to the master-slave state of each control device in the first network and the master-slave state of each control device in the second network, switching the master-slave state of at least one control device in the first network and/or the second network, so that the number of the master control devices in the train network control system is 1. And the main control device in the first network is the same as the main control device in the second network. According to the embodiment of the invention, the safe operation of the train is ensured by ensuring that the two networks of the train network control system have the unique and same main control equipment.
本申请实施例提供了一种设备冗余方法、装置、列车网络控制系统及产品,列车网络控制系统包括:多个功能设备和相互冗余的至少两个控制设备;任一控制设备通过第一网络或者第二网络与功能设备建立通信连接;方法包括:按照预设时隙,实时检测各控制设备在第一网络中的主从状态和在第二网络中的主从状态;根据各控制设备在第一网络中的主从状态和在第二网络中的主从状态,切换至少一个控制设备在第一网络和/或者第二网络中的主从状态,使列车网络控制系统中的主控制设备数量为1,并使第一网络中的主控制设备与第二网络中的主控制设备相同。本申请实施例通过确保在列车网络控制系统的两种网络中有唯一且相同的主控制设备,保障列车的安全运行。
