The invention relates to a master-slave channel redundancy management system and method for a rail transit signal system, and the system comprises a safety middleware module, a processing process for the rail transit signal system comprises a main channel and a slave channel, and forms a double-two-channel master-slave channel redundancy management architecture. The security middleware module comprises a security real-time library unit and a redundancy management unit; by updating the safety data in the safety real-time library unit in real time, the safety data are output to the rail transit signal system, clock synchronization between the main channel and the auxiliary channel is controlled according to the safety data, and judgment of the main channel and the auxiliary channel is achieved; the redundancy management unit guarantees that only one main channel outputs outwards and controls synchronization between the main channel and the slave channel in redundancy management of the main channel and the slave channel, and when a certain channel breaks down, a double-two-channel main-slave channel redundancy management framework can be automatically recovered, and redundancy management is achieved. According to the invention, the original architecture can be automatically recovered when a certain channel fails.
