摘要
随着5G技术的发展与相关生态的基本形成,加快研究5G在铁路信息系统中的应用,对推进铁路行业的智能化转型具有重要意义。通过分析铁路信息系统现状,梳理铁路领域部分主要系统目前存在的问题,分析铁路信息系统对移动网络不断提高的需求;总结了5G应用优势及铁路信息系统5G应用场景;在此基础上,研究提出了典型信息系统基于5G的技术架构。具有5G技术加持的铁路信息系统,将形成云-边-端一体化的铁路信息系统全新架构,支撑各类新型应用;系统能力从固定终端延伸至移动场景,有利于提高铁路整体运营效率;为各类基础设施检测监测、既有系统改造等场景提供便捷的无线网络接入条件,将提高铁路泛在感知能力,保障行车安全。
With the development of 5G technology and the main progress in forming 5G ecosystem,accelerating the research on the application of 5G in railway information system is crucial to fostering the intelligent transformation of the railway sector.This paper examines the current railway information system,sorts out the existing problems of some major systems in the railway sector,analyzes the increasing demand of railway information system for mobile network,and summarizes the advantages of 5G application and the application scenarios of railway information system.On this basis,the typical 5G-based technical architecture for information system is proposed.The railway information system supported by 5G technology will adopt a new architecture of an integrated cloud-edge-end system to support various new applications;the system capacity is extended from fixed terminals to mobile scenarios,which is conducive to improving the overall operational efficiency of the railway;convenient wireless network access conditions are provided for infrastructure inspection and monitoring,existing system transformation and other scenarios,which will improve the ubiquitous perception ability of railways and ensure train operation safety.
