摘　　要：城市轨道交通全自动运行系统专业性强、技术设备复杂、时效性强,在极端灾害发生时,控制中心有可能陷入瘫痪状态,导致控制中心各专业系统无法完成正常的功能,进而影响城市轨道交通的正常运营。备用控制中心为城市轨道交通全自动运行系统的必备配置,系统整体的可用性和安全性在备用控制中心加持下有较大改善。结合信号系统、通信系统、综合监控系统主备控制中心系统内部冗余切换机制、设备典型配置、系统接口切换影响及切换场景,在此基础上给出主备控制中心切换设计方案的优劣势比较,为城市轨道交通全自动运行系统建设中主备控制中心系统切换设计提供借鉴和指导。Fully automatic operation system has the characteristics of strong professionalism,complex technical equipment and strong timeliness in urban rail transit.However,operating control center(OCC)may become paralyzed in times of extreme disasters,resulting in the failure of all professional systems to complete normal functions,thus affecting the normal operation of urban rail transit.The backup operational control center(BOCC)is defi ned as the essential confi guration of the fully automatic operation system of urban rail transit,and the overall availability and safety of system are greatly improved with the addition of BOCC.This paper analyzes the internal redundant switching mechanism,the typical configuration of the equipment,and the impact of switching between the interfaces of the core professional system and the switching scenarios of the core system of OCC and BOCC of signal systems,data communication system and integrated supervision and control systems.Based on the above description and the comparison of the advantages and disadvantages of switching design,this paper provides reference and guidance for the core professional system switching design of the OCC and BOCC for fully automatic operation in urban rail transit.
