摘　　要：近年来,在国家政策的大力支持下,地方铁路蓬勃发展,由地方人民政府主导设计、施工建设,国家铁路主管部门提供必要的技术支持和施建审批。移动通信制式选择时,需依据铁路经营管理模式、机车交路、业务需求等不同特点,结合技术制式的频率资源可实施性、先进性、成熟度、运营维护是否方便、工程经济性等因素,合理选择方案。本文介绍了地方铁路目前主流的经营管理模式;研究了影响移动通信制式选择的因素;阐述了GSM-R、DMR、LTE、5G四种可选移动通信制式特性;并重点对四种可选制式从不同维度进行详细比选。In recent years,with the strong support of national policies,local railways have developed vigorously.The design and construction are led by the local people’s government,and the national railway authority provides necessary technical support and construction approval.When choosing a mobile communication system,it needs to be based on different characteristics of railway operation and management mode,locomotive routing,business needs,etc.,combined with the feasibility,advancement,maturity,convenience of operation and maintenance,and engineering economics of the frequency resources of the technical system,a reasonable plan is chosen.Firstly,this article introduces the current mainstream operation and management mode of local railways;then it studies the factors that affect the choice of mobile communication systems;thirdly,it explains the characteristics of four optional mobile communication systems:GSM-R,DMR,LTE,and 5 G;finally,it focuses on the detailed comparison and selection of the four optional systems from different dimensions.
