基于通信的城市轨道交通信号与控制系统研究

Research on Signaling and Control System of Urban Rail Transit based on Communication

伴随着社会经济的进步,我国的交通运输建设也在加速发展。尤其是城市轨道交通,在短短的几年内,地铁线路网遍布于全国各大城市,这加大了对轨道交通信号控制系统的需求。轨道列车的行驶速度快,高效、准确、及时的信息传输在交通运行过程中非常重要,传统的信息传输方式已不能满足轨道交通运输的要求。我国的交通信号系统技术还不成熟,还存在信号不兼容、传输效率低等问题。本文对不同的轨道交通信号控制系统及CBTC进行了全面的分析,旨在为信号系统技术的革新和改进提供参考。

With the progress of social economy,China's transportation construction,especially urban rail transit,is also accelerating.In just a few years,the subway line network is spread throughout major cities across the country,which increases the demand for rail transit signal control systems.The speed of rail trains is fast,and effi cient,accurate and timely information transmission is very important in the process of traffi c operation,and the traditional information transmission method can no longer meet the requirements of rail transportation.China's traffi c signal system technology is not mature,and there are still problems such as signal incompatibility and low transmission effi ciency.This paper provides a comprehensive analysis of diff erent rail transit signal control systems and CBTCs,aiming to provide reference for the innovation and improvement of signal system technology.
