| 摘 要： | 为了探讨基于通信的列车控制(CBTC)系统后备模式下追踪间隔的特性及与正常情况下追踪间隔的差异,在研究CBTC系统基本工作原理、相关移动闭塞和后备模式技术的基础上,建立了CBTC后备模式下的追踪间隔仿真模型,并对CBTC系统在移动闭塞和后备模式下的追踪间隔进行了仿真计算.结果表明:CBTC移动闭塞模式和后备模式都能满足系统要求,实现较小的追踪间隔时间;移动闭塞模式优于后备准移动闭塞模式,能够实现相对更小的追踪间隔时间(<90 s).

| Abstract: | In order to research the feature of headway in a Fallback mode and the difference to a normal mode for a CBTC(communication based train control) system,the basic principle of the CBTC system and the relative technology about moving block and Fallback modes were investigated,models for train headway in a CBTC Fallback mode were constructed,and headways in the moving block and Fallback modes for the CBTC system were simulated and calculated.The research shows that CBTC moving block and Fallback modes can meet the system requirements and achieve small train headway.Compared with the Fallback moving-like block mode,the moving block mode can achieve much smaller train headway(<90 s). |
