武汉地铁信号系统联锁边界和区域控制器边界划分方案

Solution to the Interlocking Zone and Controller Boundary in Wuhan Metro Signal System

以武汉地铁信号系统设计为例,阐述了联锁区边界划分和区域控制器边界划分的原则和方法。基于武汉地铁信号机设置原则,联锁区边界采用了“Z字形”确定方法;区域控制器的边界根据系统供应商提供的区域控制器处理能力、列车数量和后期扩展需求,设置与某个联锁区边重合。

Taking the design of Wuhan metro signal system as an example, the principle for the boundary division of interlocking zone and controller area is described. Based on the layout principle of signal equipment in Wuhan metro, the Z-type boundary for interLocking zone is recommended, and the boundary of zone controller is decided by the ca- pacity of zone controller provided by suppliers, by train numbers and the requirements of future extension, in order to overlap a certain interlocking zone.
