摘要
通过分析乘客信息系统(PIS)和列车自动控制系统(CBTC)的功能及无线局域网IEEE802.11a特点,以及通过无线局域网技术(WLAN)技术实现PIS与CBTC双向通信网络带宽需求,详细论证了PIS对CBTC系统的同频干扰、邻道干扰问题,并给出了在工程实现解决上述干扰问题的具体方案。
It is analyzed that include the function of passenger information system(PIS) and communication based train control(CBTC), as well as wireless LAN IEEE802.11 characteristics and bandwidth requirements implementing intercommunication between PIS and CBTC. Co-channel interference and adjacent channel interference of PIS and CBTC are demonstrated in detail, and the specific solution of the interference problem is given out in the project.
