The invention discloses a network voltage signal redundancy control method of an electric locomotive, and relates to the technical field of electric locomotives. The method comprises the following steps: pre-acquiring communication information of traction control units and a microcomputer, and if the current traction control unit has a fault or the communication information with the microcomputer is abnormal, not acquiring a network voltage signal of the current traction control unit, isolating thecurrent traction control unit with the abnormalnetwork voltage signal acquiring the network voltage signals of other traction control units, and raising an alarm against the acquired abnormal network voltage signal of the traction control unit. The voltage signal of the traction control unit are isolated while the fault of thetraction control unit is isolated, moreover, the network voltage signals of all the traction control units are incorporated into microcomputer monitoring, and the abnormal fault of a certain network voltage signal can be identified, so that the locomotive fault caused by the abnormal network voltage signal of the traction control unit can be effectively avoided, the operation of the locomotive is maintained, and the transmission reliability and stability of the locomotive are improved.

    本发明公开了一种电力机车的网压信号冗余控制方法,涉及电力机车技术领域,包括以下步骤:预先获取牵引控制单元与微机通讯信息,若当前牵引控制单元有故障或与微机通讯信息异常,则不采集当前牵引控制单元的网压信号,并隔离当前异常网压信号的牵引控制单元,获取其它牵引控制单元的网压信号,将获取牵引控制单元异常网压信号进行报警,本发明牵引控制单元的网压信号随牵引控制单元的故障隔离同步隔离,而且将所有牵引控制单元的网压信号纳入微机的监控中,并能够识别某一路网压信号异常故障,可有效避免牵引控制单元因网压信号异常导致的机车故障,维持机车运行,提高其传输的可靠性和稳定性。
