大型铁路枢纽GSM-R系统规划的探讨

GSM-R System Planning for Larg-scale Railway Junction Station

GSM-R系统是保障调度指挥和行车安全的重要手段。在大型铁路枢纽内,线路众多,地形复杂,且枢纽内各线的建设工期不一致,GSM-R系统在大型铁路枢纽内必须进行规划。本文从"GSM-R承载的业务";"BSC接入方案规划";"GSM-R无线覆盖、容量和干扰的平衡"3个方面对GSM-R网络规划进行了论述,在论述过程中,结合了贵阳枢纽和成都枢纽的实际情况,并且对枢纽内重点区域通过电子地图和软件进行了模拟分析。所以,做好大型铁路枢纽GSM-R系统规划,能减少后续网络建设对既有网络的影响,保证资源节约和行车安全。

GSM-R system is crucial for ensuring the trains dispatching and operation safety. A large-scale railway junction station has complicated terrain and many lines constructed in different phases. So the GSM-R system for this kind of junction stations should be planed. The paper discusses the GSM-R network planning from the three aspects such as bearer services over the GSM-R system, BSC accessing plan, as well as the radio signals coverage, capacity and interference counteraction of the GSM-R network, and it also gives a simulated analysis of the key area in the junction stations through electric map and software combining with the actual conditions of Guiyang and Chengdu junction stations. It concludes that a well planned GSM-R system for the large-scale railway junction station can reduce the impact of following network construction on the existing network and ensure resources saving and train operation safety.
