边缘计算在铁路行业的应用和价值

Application and Value of Edge Computing in Railway Industry

随着“新基建”国家战略的提出,公网运营商5G建设明显加速。而5G与行业应用结合最紧密和可落实的场景之一就是边缘计算。文章从边缘计算概念的产生出发,回顾边缘计算技术的历史发展,详细论述边缘计算技术的能力图谱,给出边缘计算的能力集合,并定性分析其工程经济性考虑因素。通过对边缘计算能力的深入理解,分析其在铁路行业应用场景的分类,从大带宽应用、数据采集与处理、灾难与应急、网络边界管理几个方面,分析对应场景的应用模式和工程建设的考虑因素。最后,简要论述铁路边缘计算的架构可能性。

With the proposal of"new infrastructure"national strategy,the construction of 5G for public network operators has accelerated significantly.One of the most tight and practical scenarios for combining 5G with industry applications is edge computing.Starting from the concept of edge computing,this paper reviews the historical development of edge computing technology,discusses the capability map of edge computing technology in details,gives the capability set of edge computing,and qualitatively analyzes its engineering economic considerations.Based on the in-depth understanding of the edge computing capability,this paper analyzes the classification of its application scenarios in the railway industry,and analyzes the application mode and engineering construction considerations of the corresponding scenarios from the aspects of large bandwidth application,data collection and processing,disaster and emergency,and network boundary management.Finally,the possibility of railway edge computing architecture is briefly discussed.
