The invention belongs to the technical field of railway signals, and discloses a railway train control system ground electronic unit N + 1 redundant hot standby method. The method comprises the steps that an independent channel is established between a standby ground electronic unit LEU N + 1 and a train control center, and a channel switching circuit is arranged between a ground electronic unit and an active transponder; the train control center periodically inquires the communication condition with the main ground electronic unit, and if the state packet of the main ground electronic unit is not obtained within the preset time, it is judged that the main ground electronic unit breaks down; when the main ground electronic unit breaks down, the train control center sends message information sent to the main ground electronic unit to the standby ground electronic unit to drive the two-way switching relay LEUj-QHJ to lose excitation and fall down; and the train control center collects the front node state of the LEU-ZFJ and the LEU-QHJ of each ground electronic unit, judges whether the front node state is consistent with the driving state or not, and gives a fault alarm if the front node state is not consistent with the driving state. According to the invention, the problems that the standby LEU needs to be switched manually after the main LEU breaks down, and the fault processing operation time is relatively long are solved.

    本发明属于铁路信号技术领域,公开了一种铁路列控系统地面电子单元N+1冗余热备方法:备用地面电子单元LEU N+1与列控中心建立独立通道,地面电子单元与有源应答器之间设置通道切换电路;列控中心周期性查询与主用地面电子单元的通信情况,若在预设时间内没有获取主用地面电子单元的状态包,则判定主用地面电子单元故障;主用地面电子单元发生故障时,列控中心将发送给主用地面电子单元的报文信息发送给备用地面电子单元,驱动双路切换继电器LEUj‑QHJ失磁落下;列控中心采集每个地面电子单元的LEU‑ZFJ和LEU‑QHJ的前节点状态,判断前节点状态与驱动状态是否一致,若不一致则进行故障报警。本发明解决了主用LEU出现故障后需人工倒换备用LEU,处理故障操作时间较长的问题。
