The invention discloses a rail transit backup degraded operation system and method based on a secondary radar, and relates to the technical field of rail transit train control, the rail transit backup degraded operation system comprises a secondary radar system, a vehicle-mounted ATP system, an OC system and an ATS system, the secondary radar system carries out train positioning and speed measurement, and the vehicle-mounted ATP system, the OC system and the ATS system are combined with the secondary radar system to control train operation. The train-train communication and train-ground communication double-safety protection link combination based on the secondary radar has higher communication capacity than traditional CBTC/TACS system communication, the train can be controlled to run to a front platform at a fixed speed limit (not smaller than 40 km/h) from an ATO or FAM mode in a backup mode, safe running and continuous operation of the train are guaranteed, and the safety of the train is guaranteed. The efficiency of the train backup control mode is greatly improved, and trackside and vehicle-mounted equipment is simple in configuration, high in stability and convenient to maintain.

    本发明公开了一种基于二次雷达的轨道交通后备降级运行系统及方法,涉及轨道交通列车控制技术领域,包括二次雷达系统、车载ATP系统、OC系统和ATS系统,二次雷达系统进行列车定位测速,车载ATP系统、OC系统和ATS系统结合二次雷达系统控制列车运行。本发明使用基于二次雷达的车车通信、车地通信双安全防护链路组合比传统CBTC/TACS系统通信具有更强的通信能力,可实现在后备模式由ATO或FAM模式控车以固定限速(不小于40km/h)运行至前方站台,保证列车安全运行和运营连续不中断,大幅提高列车后备控制模式效率,轨旁及车载设备配置简单,稳定性高,维护方便。
