The invention relates to the technical field of rail transit, in particular to a redundancy control method, system and device for vehicle-mounted operation control equipment and a medium. The vehicle-mounted double systems are independent units, the double systems and peripheral interaction data channels are independent, data interaction is periodically carried out between the main system and the standby system, various types of fault flag bits of the system are added in synchronous data of the double systems, the running condition of the opposite systems is rapidly judged, the standby system is rapidly responded to be switched into standby system running when the main system is down, and the system reliability is improved. And a 600km/h train high-speed operation switching scene is met. The automatic protection system of the rail transit train is higher in usability, safer and more reliable. The vehicle-mounted double systems are independent units and can normally communicate with peripherals when being independently used, train operation is controlled, and the situation that train operation is affected due to abnormal communication of the vehicle-mounted double systems caused by one-way interference is avoided. According to the method and the device, the conditions of standby system downtime and hot standby function failure caused by short-time communication interference, packet loss and the like can be avoided, the availability of double-system redundancy is improved, and normal operation of a train is ensured.
本公开涉及轨道交通技术领域,特别涉及一种车载运控设备的冗余控制方法、系统、设备及介质。本公开车载双系均为独立单元,双系与外设交互数据通道独立,主备系之间周期性进行数据交互,在双系同步的数据中增加本系各类型故障标志位,快速判断对系运行情况,主系宕机备系快速响应切换为备系运行,满足600km/h列车高速运行切换场景。使轨道交通列车自动防护系统可用性更高,更加安全可靠。本公开车载双系均为独立单元,单独使用都可以与外设正常通信,控制列车运行,避免一路干扰导致车载双系通信异常,影响列车运行。本公开可避免短时通信干扰、丢包等导致备系宕机,热备功能失效的情况,提高双系冗余的可用性,保证列车正常运行。
