摘　　要：地铁列车的安全运行由基于车-地双向通信的列车自动防护系统保障,当列车自动防护系统失效地铁列车降级运行时,有必要研究一种基于车-车直接通信的列车防追尾方法以保证地铁列车的行车安全。基于无线传感器网络的防追尾方法通过相应算法测量车-车直接通信信号得到追踪间隔,通过对比追踪间隔与预警阈值,给出预警信息,进而实现地铁列车的避撞防护。本文介绍两种应用于地铁列车防追尾方法中的无线测距技术,对其测距原理、设计方案进行研究分析。The safety operartion of the subway train is guaranteed by the Automatic Train Proteetion（ATP） system which is based on train-trackside radio communication. When the ATP is failure, the train operation is under degraded mode. It is necessary to study a method based on the vehiclevehicle communication technology to prevent train collision in order to ensure the safety of the subway train. The anti collision method based on Wireless Sensor Network can measure the signal of the vehicle-vehicle communication and calculate the tracking interval by the corresponding measurement algorithm. This paper introduces two wireless ranging technologies used in the anti collision method of subway train, and then discusses the ranging principle and design scheme of these technologies.
