CBTC系统列车追踪运行浅析

Brief analysis on train tracking operation on CBTC System

CBTC系统是一种利用高精度的、不依赖于轨道电路的列车定位技术,实现连续式的、大容量的双向车、地数据通信。本文简要分析了基于通信的列车运行控制系统中不同等级列车的追踪运行方式,有助于进一步从系统运用的角度理解CBTC系统。

CBTC（Communication Based Train Control） was a kind of continuous and large capacity data communication of two-way train to ground which used train positioning technology of high accuracy.The technology didn＇t dependent on track circuit.The paper analyzed tracking running mode for train of different levels in CBTC.The analysis was helpful to understand CBTC System from the angle of system application.
