Two lines may be embedded in the position of same depth.Therefore, it is necessary to convert two-dimentional drawing information to three for effective use
Location information is tieed up, we can use BIM-GIS platform and carry out 3 d structure model remodeling to 2DCAD initial data here.?
In the present embodiment, using these 3 d structure models after remodeling, collision detection can be more efficiently carried out.
In addition, updating about the data in BIM-GIS platform, user can modify to IFC model, this can be returned
To BIM integrating engine, and be converted to CityGML format.By utilizing BIM-GIS platform, it can store periodic maintenance, be based on shape
The more new information of maintenance and the preventive maintenance of state, in this way can be predictably to descend the performance management of communal facility to provide effectively
History inspection data information.
In addition, information technology used by different Urban Buried Pipeline Network implementation management departments is not quite similar, information management
System also belongs to distributed management system.There are information due to application technology and information format disunity between each distributed system
Island phenomenon.It, will be above-mentioned using the Deep integrating application technology of generalized information system and BIM system as the information management transfer mode of core
Two kinds of technologies realize integrated application from data and system level, solve the mutual conversion of the data information format between not homologous ray
Problem breaks each system, interdepartmental information barrier, realizes data interaction and information sharing.It is integrated using skill based on this
The information management mode of art is to ensure smart city underground pipe network science, efficient, safe operation effective model.
The embodiment of the present invention establishes integrated BIM system and GIS system by the data sharing between BIM system and generalized information system
The BIM-GIS platform of system；Then underground communal facility information is obtained from BIM-GIS platform, and is calculated according to preset machine learning
