大秦线GSM—R应用业务运营维护管理系统分析

Analysis on Operation,Maintenance and Management System of GSM-R Application on Datong-Qinhuangdao Line

大秦线GSM—R网络现已开通机车同步操控(LOCOTROL)业务、调度命令与无线车次号传输业务、可控列尾业务等。其中,LOCOTROL与GSM—R的结合是大秦线GSM—R的第一业务和最关键业务。为保证GSM—R网络通信安全,提出LOCOTROL业务的网络运营维护体系与措施,介绍面向业务维护的LOCOTROL通信监测系统组成中的PRI接口监测系统、A接口监测系统和Abis接口监测系统等子系统功能。

The GSM-R network of Datong-Qinhuangdao line has opened the services of LOCOTROL,dispatching order transmission,radio transmission of train number,controllable EOT,etc..Among those services,the combination of LOCOTROL and GSM-R is the most crucial one.For the safety of GSM-R network communication,the paper proposes the network operation and maintenance mechanism and measures of LOCOTROL service,and introduces the subsystem functions of the maintenance-related LOCOTROL communication monitoring system,such as its PRI interface monitoring system,A interface monitoring system,and Abis interface monitoring system.
