The invention provides a rail transit signal system switching device. The rail transit signal system switching device comprises a switching relay module and a fault operation switching module. The switching relay module comprises at least one switching relay, each switching relay comprises a middle contact, a positioning contact and an anti-position contact, the middle contact is connected with trackside equipment through the fault operation switching module, the positioning contact is connected with a new system, and the anti-position contact is connected with an existing system; when the new system is connected with the trackside equipment, the middle contact is connected with the positioning contact; when the existing system is connected with the trackside equipment, the middle contact is connected with the anti-position contact; and the fault operation switching module is connected between the rail-side equipment and a contact in each switching relay. According to the invention, fault state monitoring can be carried out on the switching equipment, and corresponding emergency processing can be carried out after a fault occurs; furthermore, a switching cabinet does not need to be specially arranged, and the space in a signal equipment room can be saved.
本发明提供了一种轨道交通信号系统倒切设备,包括:倒切继电器模块和故障运行切换模块;倒切继电器模块包括至少一个倒切继电器,每个倒切继电器包括中接点、定位接点和反位接点,其中,中接点通过故障运行切换模块与轨旁设备连接,定位接点与新系统连接,反位接点与既有系统连接;在新系统与轨旁设备接通的状态下,中接点与定位接点连接;在既有系统与轨旁设备接通的状态下,中接点与反位接点连接;所述故障运行切换模块连接在轨旁设备和各个倒切继电器中接点之间。应用本发明可以对倒切设备进行故障状态监测,并可以在故障发生后采取相应的应急处理;进一步地,无需专门设置倒切柜,可以节省信号设备室内的空间。
