地铁综合监控系统建设延伸线网络接入方式探讨

地铁线路分期建设时,综合监控网络接入既有线的联网方式有破环网接入组网和延伸线独立组网。为确保延伸线交换机设备可靠接入既有线综合监控主干网,对上述两种方式的性能分析进行对比并提出实施性建议,结果表明,独立组网的单点故障切换时间仅为1秒,减小了网络单点故障对网络的影响,提高了综合监控网络健壮程度,保证网络更加稳定运行以便后期运营维护。

When the subway line is constructed in stages,the integrated monitoring network connects to the existing line in the form of broken ring network access network and extended line independent network.In order to ensure the reliable access of the extension line switch equipment to the existing line integrated monitoring backbone network,the performance analysis of the above two methods is compared and the implementation suggestions are put forward.the results show that the single point failover time of the independent networking is only one second.It reduces the influence of network single point failure on the network,improves the robustness of the integrated monitoring network,and ensures the more stable operation of the network for later operation and maintenance.
