市域铁路与国铁共线运营专用无线通信系统方案研究

Scheme of Dedicated Radio Communication System for Co-operation between Suburban Railway and National Railway

针对市域铁路与国铁共线运营的运输组织模式,从两种不同铁路制式下的专用无线系统业务需求分析着手,根据行业规范和技术现状,重点研究GSM-R系统和LTE-M系统共存的总体技术方案和无线覆盖方案,并提出两个专用无线系统共用漏泄同轴电缆的方案。

According to the co-operation transportation organization mode of national railway and city railway,this paper analyses the traffi c requirements of dedicated radio system under two diff erent railway systems,focuses on overall technical scheme and radio coverage scheme of GSM-R system and LTE-M system on the basis of industry specifi cation and technical status,and proposes the scheme of sharing leakage coaxial cable overlaying between two dedicated radio systems.
