Research On Railway Informatization Construction And Application Architecture Based On 5G-R

The State Railway Group’s "14th Five-Year Plan" Railway Network Security and Informatization Planning proposes to "build a high-speed,safe and ubiquitous new generation information network integrating IPV6 and 5G",and makes detailed planning for the development of informatization in the future to open up the whole-process ecological chain of "production,supply,transportation and marketing",provide guarantee for the automation,intelligent and refined development of railway transportation production organizations,empower high-quality development of railways,and build "smart railways".Based on the requirements of railway informatization development such as business needs,network security and information sharing,the construction of a railway-specific basic bearer network with large transmission bandwidth,fast transmission rate,wide line coverage and high wireless degree is the most urgent need for the construction of railway information network.The railway-specific wireless communication network using the Fifth Generation of Mobile Communication（5G）is not only the future development direction of railway wireless communication,but also the most effective means to solve the constraints of railway information development network infrastructure.This paper analyzes the development status and future planning of the new railway information system,combines the future development requirements,focuses on the contradiction between the current demand for the rapid development of railway informatization and the backward infrastructure construction,and puts forward the network basic requirements for solving the bottleneck of informatization development.Combined with the development process of railway wired communication and wireless communication at different stages,the business carried by railway communication network is introduced.This paper focuses on the main problems existing in the current communication network and the bottlenecks in the development of the existing wireless communication system,and makes a specific analysis of the current situation of the communication network and the development limitations of the railway information system.From the perspective of technology development and policy planning,the inevitability of the development of 5G-R wireless communication system is analyzed,the system structure,service application and main characteristics of 5G-R are analyzed and studied,and the advantages of railway informatization construction and application combined with the development of railway informatization are expounded in combination with the planning of railway informatization development.Combined with 5G-R technology,this paper explores the model of railway information construction and application architecture based on 5G-R,and compares the advantages of railway information construction and application architecture based on5G-R in view of the development of railway information service.Figure 18,Table 3,Reference 26.
