The invention provides a main and standby system switching system and a main and standby system switching method, the system comprises an interlocking A system and an interlocking B system, the interlocking A system comprises a first relay interlocking circuit, the interlocking B system comprises a second relay interlocking circuit, and each of the first relay interlocking circuit and the second relay interlocking circuit comprises a first contact pair and a second contact pair; the first contact pair is used for outputting main and standby system states of an interlocking A system to the first relay interlocking circuit; the second contact pair is used for outputting main and standby system states of the interlocking A system to the second relay interlocking circuit; the first relay interlocking circuit is used for determining whether to perform main and standby system switching on the interlocking A system according to the main and standby system state of the interlocking A system and the main and standby system state of the interlocking B system; and the second relay interlocking circuit is used for determining whether to perform main-standby system switching on the interlocking system B according to the main-standby system state of the interlocking system A and the main-standby system state of the interlocking system B. By the adoption of the technical scheme, double main systems can be avoided, and running safety of the train is guaranteed.

    本发明提供一种主备系切换系统和主备系切换方法,系统包括联锁A系和联锁B系,联锁A系中包括第一继电器互锁电路,联锁B系包括第二继电器互锁电路,第一继电器互锁电路和第二继电器互锁电路均包括第一触点对和第二触点对;第一触点对用于向第一继电器互锁电路输出联锁A系的主备系状态;第二触点对用于向第二继电器互锁电路输出联锁A系的主备系状态;第一继电器互锁电路,用于根据联锁A系的主备系状态和联锁B系的主备系状态,确定是否对联锁A系进行主备系切换;第二继电器互锁电路,用于根据联锁A系的主备系状态和联锁B系的主备系状态,确定是否对联锁B系进行主备系切换。采用本发明的技术方案可以避免双主系的出现,保证列车运行安全。
