摘　　要：车载控制器(CC)是负责地铁列车安全监督和运营管理的核心控制器,列车两端各安装1套车栽控制器(CC1和CC2),实现硬件冗余和软件热备。通过健康参数筛选以及优先级排序,计算得到健康度,用于判定CC的优劣性;并设计了一套切换策略,以实现主备CC无缝切换,保证车载控制器的实时性、冗余性和可靠性。The train-borne controller is the key controller for train safety surveillance and opera­tional management of the metro.Usually,there are two CCs.CC1 and CC2.respectively in stalled on the two ends of a train,realizing redundancy in hardware and hot-standby in software.By using health parameters selected and prioritized,the degree of health can be calculated to de­termine which CC is in better condition.Besides,a set of cut-over strategies are designed to meet CC's seamless handover so as to assure the real-timeness,redundancy and reliability of the CC.
