摘　　要：为有效解决城市轨道交通双控制中心模式下冗余机制失效问题,以某线路控制中心网关计算机故障无法切换为例,分析该线路双控制中心模式下的冗余机制设计原理及存在问题,提出有效整改方案,并在该线路进行软件优化验证。经过观察,系统的可靠性及抗干扰性等均得到显著提升,提出的整改方案能够有效提高系统可用性。In order to effectively solve the problem of the failure of the redundancy mechanism in the dual-control-center mode of urban rail transit,this paper uses the failure of a gateway computer of a line control center as an example.It analyzes the design principle and existing problems of the redundancy mechanism in the dual-control-center mode of the rail transit line,proposes an effective rectification plan,and carries out software optimization verification for the rail transit line.After observation,the reliability,redundancy and anti-interference capabilities of the system have been consolidated,demonstrating that the rectification scheme proposed in this paper can effectively improve the availability of the system.
