CBTC系统无线干扰分析与优化措施

Measures and Analysis of CBTC Radio Interference in Urban Rail Transit

介绍城市轨道交通CBTC无线通信系统基本构成原理;主要针对CBTC无线通信系统存在的干扰源进行分析;并通过采用双网双信道冗余设计、AP冗余部署、无线覆盖方式选择及传输速率动态调整等抗干扰措施,有效提高CBTC无线通信系统的抗干扰能力。

The paper explains the basic composition and principle of CBTC radio system for urban rail transit and focuses on analyzing the interference sources of CBTC radio system.Through adopting redundant design of twin-wire,dual-channel,wireless coverage,AP redundant deployment and dynamic adjustment of transfer rate and so on,effectively improving the anti-interference ability of CBTC wireless communication system.
