摘要:: 随着铁路客站的大规模发展，客站的运营管理对无线通信提出了更高的要求。本文研究了现有铁路客站无线通信系统使用情况，对比分析了DMR、Wi-Fi、LTE和公网等技术的特点及存在问题。针对铁路客站作业的基本需求和智能客站的发展，提出了DMR叠加宽带无线通信的铁路客站无线通信系统发展方向，采用DMR技术解决客站最基本的生产作业组织需求，采用宽带无线通信系统解决智能客站对宽带数据的传输需求，并通过宽窄带融合技术，实现两者之间的互联互通。

Abstract:: With the large-scale development of railway passenger stations, the operation and management of passenger stations set higher requirements for wireless communication. This paper studies the use of existing wireless communication systems in railway passenger stations, and compares and analyzes the characteristics and existing problems of DMR, Wi-Fi, LTE, and public network technologies. In view of the basic needs of railway passenger station operation and the development of intelligent passenger stations, wireless communication system of railway passenger stations with DMR superimposed broadband wireless communication is proposed as the development direction. DMR technology is adopted to solve the basic operation and organization needs of the passenger stations, while the broadband wireless communication system is adopted to solve the broadband data transmission needs of the intelligent passenger stations, and the interconnection between them is realized through wide and narrow band convergence technology.
