Design And Implementation Of Digital Archives Management System For Railway Engineering Construction Enterprises

In recent years,the country has put forward the outline of building a transportation power and the outline of comprehensive three-dimensional transportation planning,and railway transportation has made great achievements.The continuous development of infrastructure projects has resulted in a huge number of completed and ongoing engineering archives,and the difficulty of management has also increased.Aiming at the problems of low management efficiency,low utilization degree and BIM model digital file format diversity,huge volume,difficult loading and other problems in paper file management,this paper combines cloud computing,Internet of things,BIM,network communication and other technologies,based on microservices and B/S architecture,studies and designs the digital file management system for railway engineering construction enterprises,and realizes the full life cycle management of digital files:(1)Explain the background and significance of the paper research,introduce the relevant technologies and algorithms of the system implementation,and analyze the system requirements.The research content of this paper is sorted out,the management methods and methods of digital files are studied,the system development technology and BIM technology are introduced,and the theories of system database,Nginx server and load balancing algorithm are expounded.According to the research content,the business requirements of the system,BIM file visualization requirements,system functional requirements and non-functional requirements of the system,are analyzed.(2)To study the visualization of the digital archives of the railway BIM model.According to the requirements of BIM model digital file management,the IFC format standard,parametric modeling,model rendering,BIM lightweight technology,using BIM engine technology loading model,BIM model digital file format unified,model creation,model rendering,volume reduction,BIM model visual loading effect,finally build directory tree,realize the quick browsing function of related engineering archives.(3)Design,implement,and test the digital file management system.Based on the requirement analysis and research results,design the functional architecture,BIM model digital file visualization and database of the system;develop Java programming language digital file management system for railway engineering construction enterprise,realize the functions of file entry,file management,BIM file visualization and BIM file application of the system;use black box test method;and test on the concurrent performance and transaction processing capability of the system server using Jmeter automatic test tool.
