摘要
CBTC技术在我国轨道交通中已经从理论探讨阶段进入到广泛的工程实施阶段。本文针对基于通信的列车控制系统的特点,分析了目前成熟CBTC系统中车-地通信的内容和方式;着重论述了其中无线传播方式的部分,并对各种方式的优缺点进行了比较;最后提出了地铁相关单位在规划阶段需要考虑的问题。
The development of CBTC technology in China has been stepped into the project implementation phase from the principle study. Based on the characteristics of CBTC system, this paper analyzes the content and method of wayside-train communication in a matured CBTC system, and especially on the radio communication part. After the comparison of different communication methods, some problems are raised up for the relevant departments of metro to consider during planning.
