Problems solved by technology

Some mainstream commercial software can also realize the data format conversion between BIM and GIS, but it is limited to the lower level of detail model conversion, the division relationship corresponding to the LOD level is vague, and the degree of coupling with semantic information is not high
IFC and CityGML are common data model standards in the fields of BIM and GIS respectively. The sharing of geometric and semantic information between the two will lay the foundation for the

Abstract

The invention discloses a method for constructing a spatial semantic database based on BIM and GIS data integration. The method comprises the following steps: analyzing spatial data of BIM and GIS models; establishing mapping rules of object model related attribute description fields of IOT equipment and BIM and GIS model object attribute description fields, and constructing a relational database;extracting spatial semantic information, establishing a spatial semantic mapping relation table, and constructing a graph database; constructing a time sequence database according to the time sequence data transmitted by the IOT equipment; storing spatial semantic information in a graph database, storing relational data and static business data in a relational database, storing Internet-of-thingsdata in a time sequence database, and reading data interfaces of all the databases through a visualization engine. According to the method, a data storage standard of a BIM + GIS model is established, and fusion application is realized, so that a digital twin system application mode and a technical framework integrated with key technologies such as ontology, semantic mining, Internet-of-things, big data analysis and the like are constructed.

Description

technical field [0001] The invention relates to the technical field of BIM and GIS data integration, in particular to a method for constructing a spatial semantic database based on BIM and GIS data integration. Background technique [0002] In the context of rapid urbanization, the integration of building information modeling (BIM) and geographic information system (GIS) has been increasingly researched and applied to fields related to architecture and urban management. BIM is the integration of physical and functional information throughout the life cycle of a building, containing rich and detailed structural information. However, BIM often does not include the information of the surrounding environment of the building, and it is difficult to be applied to environmental assessment, resource arrangement and safety analysis. GIS can realize geospatial visualization analysis and decision-making based on the function and physical spatial relationship of the outdoor environment...
