1. The introduction of the underground pipeline management information platform
Based on the GIS technology, the underground pipeline network information management platform adopts C/S, B/S hybrid network technologies, integrates 2D and 3D integrated technology, 3D visualization technology, big data storage technology, high-performance cache slicing technology, etc. Also, based on the oblique photogrammetry technology, the 3D scenes of the downtown can be built, which integrates the road attribute information, the building attribute information, and the underground pipeline network attribute information to create a platform integrates the functions of urban underground pipe network information browsing, query and information management based on 2D and 3D integration technology.
2. The construction content of the underground pipeline network system
2.1 The construction of ground building model
The content is the construction of the ground building current status model, and the oblique photogrammetry technology is used for automatic modeling.
2.2 The underground pipeline network 2D and 3D integration application management system
Based on the C/S network architecture, the 3D visualization of various underground pipeline network data in the city can realize the functions of 2D and 3D integration browsing, query positioning, statistics, decision analysis and system and data management through secondary development.
2.3 The underground pipeline network information service platform
Based on the B/S network architecture and the release of various underground pipeline network data and terrain data of the city, the platform can realize the functions of underground pipeline network data browsing, query positioning, statistics, decision analysis, system and data management, portal website and others through secondary development.
2.4 The urban underground pipeline network supervision and mapping subsystem
Based on the AutoCAD platform, the system adopts the single-machine architecture to realize the functions of data entry, database construction, mapping and supervision inspection in the underground pipeline network through secondary development.
