摘要
基于通信的列车控制系统CBTC技术在城市轨道交通中已得到广泛应用。本文针对基于无线通信的列车控制系统的技术方案,分析了目前CBTC系统车地无线通信的方式,将WALN和LTE的特点进行了对比。结合实际应用案例,认为LTE承载CBTC列车控制信息的能力满足CBTC列车控制系统对无线传输系统的指标要求。
CBTC technology based on corrmmnication train control system has been widely used in urban rail transit. Based on the technical scheme of train control system based on wireless communication, this paper analyzes the current wireless communication mode of CBTC system, and compares the characteristics of WALN and LTE. Combined with the practical application of the case, that LTE bearer CBTC train control information to meet the CBTC train control system on the wireless transmission system requirements.
