地铁延长线过渡期的中央级综合监控系统调度管理方案

On the Dispatching Scheme of ISCS Center on Metro Extension Line During the Transition Period

地铁延长线三权移交后到正式接入既有线路通常会有过渡期。为解决过渡期中央级综合监控系统对延长线供电系统和机电系统相关设备的调度管理问题,分析比较了软件屏蔽方案、独立主干网方案及远程连接技术方案的优缺点。阐述了远程连接技术的实现原理。远程连接技术利用虚拟局域网技术和静态路由技术,将既有线和延长线划分为不同的局域网。不仅隔离了既有线和延长线的综合监控网络,而且成功避免了延长线网络不稳定或调试期间产生的设备报警及故障事件过多对既有线路的正常运营造成影响。应用实例表明,远程连接技术成功实现了广州地铁6号线一期浔峰岗运营控制中心对6号线二期供电系统和机电系统相关设备的监控功能。

There is usually a transition period after the metro extension line being handed over and opened officially.To solve the dispatching management problems of the ISCS Center on the PSCADA（power supervisory control and data acquisition）and the BAS（building automatic system）in that period,the advantages and disadvantages of the software shielding scheme,independent backbone network scheme and remote connection technical scheme are compared.Practical application shows that the remote connection technical scheme has realized the monitoring functions of Xunfenggang Control Center on the first phase of Guangzhou metro Line 6 extension over the PSCADA and the BAS of the second phase of Line 6 extension.
