基于通信的列车运行控制(CBTC)技术在保证行车安全的前提下,可以极大地提高行车效率,满足城轨列车高密度快速运行的需要。其基于无线通信的理念和实现移动闭塞的基本应用,非常符合我国城轨交通事业的技术需要,许多新建线路采用这一技术作为控车方案。介绍了CBTC的定义,分析其结构组成,并对其中的关键技术——移动闭塞和车-地通信,进行了深入地分析。着重阐述了三种车-地通信方式和工程设计方案比选需考虑的因素,并对其适用范围进行了比较。
Based on communication train operation control (CBTC) technology to ensure traffic safety under the premise, can greatly improve traffic efficiency, to meet the needs of high-speed urban rail rapid operation. Based on the concept of wireless communication and the basic application of mobile blocking, it is very much in line with the technical needs of China’s urban rail transit. Many new lines use this technology as a control program. Introduced the definition of CBTC, analyzed its structure and made in-depth analysis of the key technologies in this area - mobile blocking and vehicle-ground communication. The three factors that need to be considered in the comparison and selection of three kinds of vehicle-ground communication methods and engineering design are emphatically described, and their applicable scopes are compared.
