Research of 3D WebGIS Platform for Maintenance and Management of Railway Public Works Equipment
To improve the technical connotation and refinement level of railway public works equipment maintenance management,a three-dimensional WebGIS platform was constructed using real 3D,BIM,and GIS technologies.With the 3DGIS ledger of railway public works established,the platform constructed a digital twin world of the railway labor and realized the dynamic visual maintenance of disease problems.The integrated engineering equipment model and railway 3D realistic geographic information data was networked and called in the platform with the help of the Cesium engine and the collaborative management of engineering facilitied 3D scene and equipment maintenance informatization was achieved.By setting equipment maintenance inspection cycles,automatic prompts and warnings were provided for production inspection tasks.The system could build a three-dimensional GIS public works management service for the whole chain of facility governance,problem filling,information visualization,rectification and maintenance,data analysis for the railway front-line public works departments,which can effectively improve the informatization and intelligence level of railway public works management.
