As a specific implementation mode, in the application, a buffer area is set for the boundary of the underground civil engineering space three-dimensional information model in order to enhance the efficiency of data acquisition and updating cooperation of the underground space, and guarantee desensitization integrity of data sharing. The buffer area range extends in the boundary normal direction, and after the buffer area range is set, the underground civil engineering space three-dimensional information model can independently perform random position deviation and scale expansion change according to individuals in the range, so that the data display range is changed; it should be noted that the attribute information in the buffer area range is prohibited from being accessed, the larger the buffer area is, the larger the data change range is, and the smaller the buffer area is, the more accurate the model information is, and different buffer areas may affect the data content displayed by the three-dimensional civil engineering space model. This protects the security of the underground civil space data and the internal pipeline asset data.
After the access authority passes, an industry use unit can call the underground civil engineering space three-dimensional model limited by the range of the buffer area, collected data are recorded in key components and hierarchical information in the civil engineering space three-dimensional model according to the monomer requirement on the basis of the underground civil engineering space three-dimensional model, after the industry asset component model is built, the relationship among the industry asset components in the civil engineering space three-dimensional model needs to be further associated, and the access points of the same industry asset component are recorded and used as line patrol bases.
