摘要
目前铁路平面调车无线通信采用模拟常规对讲方式,存在占用频率资源较多、干扰严重等问题。GSM-R作为铁路新一代数字移动通信系统,可以考虑用来解决铁路平面调车无线通信业务。本文分析了平面调车业务的技术要求,比较了当前基于GSM-R技术解决平面调车无线通信的几种技术方案,并提出相关建议。
At present, traditional analog wireless interphone is used for fiat shunting in marshalling yard. But there are some problems exit in this system, such as unreasonable utilization of frequency resources and heavy interference. GSM-R as the new generation digital mobile communication system of railway could be selected as the solution. This paper analyzes the technical requirements for wireless communication of flat shutting, compares the different schemes based on GSM-R, and then puts forward some relevant suggestions.
