无线CBTC信号系统工作模式分析

摘要

随着基于通信的列车控制(CBTC)技术的发展,无线CBTC信号系统的运营组织越来越灵活多样.综合ATS(列车自动监控)层面的中心控制模式和紧急站控模式,轨旁设备的CBTC模式和后备模式,以及车载设备的ATO(列车自动驾驶模式)、ATPM(列车自动防护的人工模式)和WSP(轨旁信号保护模式)等模式,全面分析了无线CBTC系统的工作模式.%With the rapid development of CBTC technology, the operation of radio CBTC signaling system becomes more flexible. In this paper, the OCC (operation coritrol center) control mode and emergency local control mode of ATS, CBTC mode and fallback mode of wayside, as well as on-board ATO/ATPM and WSP( Wireless Application Protocol) are introduced, the radio CBTC system operation mode is overall analyzed, which will be a good guideline for metro vehicles operation and maintenance.
