摘要
GSM-R是保障铁路行车安全的重要基础设施。针对正在新建的山区铁路,以及既有山区铁路电气化改造时进行的无线通信方式改造,研究山区铁路GSM-R覆盖方案。分析山区无线覆盖的难点,在满足无线通信系统覆盖要求的同时,充分考虑铁路行车安全、施工便利性及开通后的运营维护成本,提出山区铁路GSM-R覆盖方案。并以京原铁路为例,阐述方案应用与优势分析,为类似工程提供参考。
GSM-R is an important infrastructure to ensure the traffic safety of train operation. GSM-R coverage scheme is studied for the new mountain railway under construction and the radio communication mode upgrade during the electrification reconstruction of the existing mountain railway. This paper analyzes the difficulties of wireless coverage in mountainous areas, fully considers the railway traffic safety, construction convenience and O&M costs after opening to traffic while meeting the coverage requirements of radio communication system,and puts forward the GSM-R coverage scheme for mountain railways. Taking Beijing-Yuanping Railway as an example, the application and advantage analysis of the scheme are described to provide reference for similar projects.
