单轨交通信号系统无线覆盖重叠问题解决方案

Solution on Wireless Coverage Overlap Problem of Single-track Signalling System

在重庆单轨交通三号线信号系统项目中,正线和试车线线路部分重叠,因为正线与试车线的网络相互独立,无法完全避免正线行驶的车辆与试车线轨旁AP的关联以及试车线行驶的车辆与正线轨旁AP的关联所引起的通信中断。介绍针对无线重叠问题进行研究提出的解决方案。

In signaling system project of Chongqing single-track metro line 3, as the networks of main line and testing line are independent from each other, main line and testing line are partly overlapped with each other, so communication interruption caused by interaction between train operating on main line and wayside AP of testing line or train operating on testing line and wayside AP of main line cannot be completely avoided. So, this article introduces the solution to wireless overlap problem.
