The invention belongs to the technical field of railway signals, and provides a hot standby redundant LEU system and equipment, and the system comprises a first LEU subsystem, a second LEU subsystem and a switching module. The first LEU subsystem comprises a first circuit module and a first power supply communication module which are electrically connected, and the first power supply communication module receives a power supply signal and a first input signal through a first input cable; the second LEU subsystem comprises a second circuit module and a second power supply communication module which are electrically connected, and the second power supply communication module receives a power supply signal and a second input signal through a second input cable; the first circuit module sends a first output signal to the switching module, the second circuit module sends a second output signal to the switching module, and the switching module sends the first output signal or the second output signal to the active transponder through the output cable. According to the hot standby redundant LEU system, the integration level of the LEU system and equipment is improved, the cable cost is reduced, and the size of the LEU equipment is reduced.

    本公开属于铁路信号技术领域,提供了一种热备冗余LEU系统和设备,所述系统包括第一LEU子系统、第二LEU子系统和切换模块;第一LEU子系统包括电连接的第一电路模块和第一供电通信模块,第一供电通信模块通过第一输入线缆接收供电信号和第一输入信号;第二LEU子系统包括电连接的第二电路模块和第二供电通信模块,第二供电通信模块通过第二输入线缆接收供电信号和第二输入信号;第一电路模块向切换模块发送第一输出信号,第二电路模块向切换模块发送第二输出信号,切换模块通过输出线缆向有源应答器发送第一输出信号或第二输出信号。上述热备冗余LEU系统提高了LEU系统和设备的集成度,降低了线缆成本,减小了LEU设备的体积。
