摘要
首先对当前常用的列车定位方法及其优缺点进行概述,指出列车无线定位是下一步需要发展的方向。然后对铁路移动通信系统(GSM-R)作了介绍。提出一种基于GSM-R的列车无线定位方法,通过修改GSM-R部分协议内容达到目的,并对该方法的结构和具体实现作出说明。鉴于列车定位的重要性,将无线定位方法用于铁路行业还有待于更多的实验和检验。
The paper summarizes advantages and disadvantages of existing train positioning methods and puts forward that train wireless positioning will be the developing trend with the introduction of GSM-R system. It explores a train wireless positioning method based on modification of partial GSM-R protocol and explains the structure and implementation of the method. In view of the significance of train positioning, train wireless positioning method should be further tested and verified.
