既有线GSM-R改造中既有传输系统配置运用方案

Existing Transmission System Confi guration Scheme in Reconstruction of GSM-R System for Existing Lines

既有线无线列调改造为GSM-R系统后,能大大提高列车无线调度通信运用质量,传输系统作为承载网络,在既有线GSM-R改造工程中需满足GSM-R系统及其他既有和新增业务承载需求。结合呼和浩特铁路局大包线GSM-R改造工程,简谈既有线GSM-R改造中既有传输系统配置运用方案。

When GSM-R system is used in reconstruction of existing lines, it will greatly improve the wireless train dispatching communication quality. As the bearing network, the existing transmission system needs to meet requirements of GSM-R system and other existing and new businesses in reconstruction. Combined with reconstruction of the GSM-R system for Datong-Baotou line of Hohehot Railway Administration, the paper introduces the existing transmission system configuration scheme in reconstructing GSM-R system for existing lines.
