Design and Application of Intelligent Operation and Maintenance Management Platform for Railway Infrastructure Based on 5G+BIM
To achieve the integration and linkage of railway infrastructure operation and maintenance,this paper,in response to the difficulties in the maintenance phase of the railway infrastructure,such as connecting a large number of monitoring devices,real-time perception of device status,resource scheduling of production elements,and monitoring of maintenance operation processes,uses 5G digital new infrastructure to empower BIM technology and proposes the digital fusion application method of 5G+BIM technology to form an application model of"digitalization-systematization-intellectualisation"synergy and mutual feedback for railway infrastructure operation and maintenance management.On this basis,the overall architecture,network architecture,and 5G application mode of railway infrastructure intelligent operation and maintenance management platform based on 5G+BIM are designed with focus on the diversified and comprehensive application requirements of railway infrastructure intelligent operation and maintenance.Combining the characteristics of wide connectivity,large bandwidth and low latency of 5G communication,the research and development covers such functions as infrastructure status monitoring,video monitoring of key areas,detection of maintenance and repair operations process management,intelligent operation and maintenance auxiliary decision-making,fault disposal and emergency rescue command and dispatch,and remote control of intelligent devices.The platform realizes the railway bureau group company,station section,workshop and work area of four-level department daily operation and maintenance production whole process real-time monitoring,positioning tracking,early warning analysis,mobile communication,emergency disposal,unmanned watch and other refine and precise managements.The platform is applied to a railway bureau group company's power supply,housing construction professional infrastructure operation,and maintenance management process.The results show that the efficiency of operation and maintenance management unit can be improved by 30%,production costs reduced by 20%,the economic benefits are significant.At the same time,with the gradual acceleration of the development of intelligent high-speed railways,the construction of the platform will promote the development of intelligent operation and maintenance of high-speed railway and provide some technical reference for the realization of the full life-cycle digital twin of railway infrastructure in the future.
