The invention belongs to the technical field of railway signals, and discloses a railway train control system ground electronic unit redundancy automatic switching method and system. A switching logic controller is arranged and comprises a main control chip, a power module, an LEU front channel switching module and an LEU rear channel switching module; the LEU front channel switching module is connected between the train control center and the LEU, and the LEU rear channel switching module is connected between the LEU and the active transponder; the main control chip is connected between the LEU front channel switching module and the LEU rear channel switching module; the power supply module is connected with the LEU front channel switching module, the LEU rear channel switching module and the main control chip; the communication condition of the train control center and the LEU is periodically inquired, and if the state packet of the primary LEUi is not obtained within the preset time, it is judged that the primary LEUi breaks down; when the main LEUi breaks down, the LEUi-QHJ is driven to lose excitation and fall down, so that the front contact of the LEUi-QHJ is disconnected. The problems that after the LEU breaks down, maintenance personnel need to manually switch the standby LEU, and the operation time for processing the fault is 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冗余自动切换方法及系统:设置切换逻辑控制器,切换逻辑控制器包括主控芯片、电源模块、LEU前通道切换模块和LEU后通道切换模块;LEU前通道切换模块连接在列控中心与LEU之间,LEU后通道切换模块连接在LEU与有源应答器之间;主控芯片连接在LEU前通道切换模块和LEU后通道切换模块之间;电源模块与LEU前通道切换模块、LEU后通道切换模块和主控芯片相连接;周期性查询列控中心与LEU的通信情况,若在预设时间内未获取主用LEUi的状态包,判定主用LEUi故障;主用LEUi故障时,驱动LEUi‑QHJ失磁落下使LEUi‑QHJ前接点断开。本发明解决了LEU故障后,需维护人员人工倒换备用LEU,处理故障的操作时间较长的问题。
