铁路GSM-R网络编号方案关键问题研究

Research on Key Problems of Railway GSM-R Network Numbering Program

铁路枢纽地段地形复杂,客货运大小车站相连,且线路较为密集;高速铁路、客运专线、城际铁路、客货混跑铁路纵横交错,因此GSM-R移动通信系统除了在前期设计阶段中进行相应规划外,在后期GSM-R网络编号方案中需要对既有线路进行分析,同时对本线数据进行合理编制。结合郑州铁路枢纽的实际情况以及相邻线路GSM-R网络编号方案,对郑机城际铁路GSM-R网络编号方案当中遇到的重点与难点进行相应分析,最终形成郑机城际铁路GSM-R的网络数据报表。通过报表中的数据可以看出,合理的GSM-R网络编号方案,可以充分利用GSM-R系统的既有资源,同时可以为铁路运输提供更好、更准确的服务。

The railway hub area is located in a complicated terrain,where passenger and freight transport stations of various sizes are connected by intensive lines,and high-speed passenger dedicated line,inter-city railway,passenger and freight mixed railway are crisscrossed.Therefore,in addition to the corresponding planning in the design phase,the GSM-R mobile communication system should also need to analyze the existing lines in the latter phase of the GSM-R network numbering program and prepare data of this line reasonably.In combination with the actual situation of Zhengzhou hub and the GSM-R network numbering program of the adjacent line,this paper analyzes the key points and difficulties encountered in the GSM-R network numbering program of Zhengzhou-Xinzheng Airport Intercity Railway,and generate data report of Zhengzhou-Xinzheng Airport Intercity Railway GSM-R network.The data in the report shows that a reasonable GSM-R network numbering program can take full advantages of the existing resources of the GSM-R system,and provide better and more accurate services for rail transportation.
