基于无线通信的列车控制系统与乘客信息系统的无线网络建设方案探讨

On the Wireless Network Plans of CBTC and PIS Systems

针对目前城市轨道交通领域CBTC(基于无线通信的列车控制)系统与PIS(乘客信息系统)无线网络共存的现状,分析了两系统的无线网络传输要求,提出了三种建设方案,并对系统中可能存在的干扰问题提出了一些防范措施。

The wireless networks of the signaling system and the PIS system are now coexistent in urban rail transit. Through an analysis of the two systems＇ wireless network transmission requests, this paper proposes three construction plans, and puts forward some countermeasures against the disturbance problems which exist now in the wireless systems.
