BIM model specification detection device and detection method based on semantic retrieval

Abstract

The invention discloses a BIM (Building Information Model) specification detection device based on semantic retrieval. The detection device includes a specification and model input module, a conversion module from building specification to semantic query, a semantic information extraction module of a BIM, a semantic model generation module of the BIM, a specification integrity detection module and a specification conformity detection module. According to the detection device, extraction is carried out on the BIM on the basis of specification requirements, detection space is reduced, and the query efficiency of semantic detection is improved; and an SPARQL (SPARQL Protocol and RDF Query Language) and OWL (Web Ontology Language) ontology technology are introduced, and the problem that a storage format of the BIM is hard to be efficiently retrieved is solved.

Description

technical field [0001] Involving the integrity and compliance detection of building information models, it is a method and means to automatically detect the quality of building information models, and it is applied to various stages of design, construction, operation and maintenance in the engineering field with high quality requirements of building information models. Background technique [0002] In the design, construction, operation and maintenance stages of the building's full life cycle, a series of compliance tests must be passed to ensure the safety and availability of building products. Major disasters, accidents and severe losses due to building non-compliance are not uncommon. At present, the compliance inspection of most buildings is still carried out manually, which will inevitably lead to problems such as low efficiency of inspection and errors and omissions. [0003] BIM (Building Information Model) is a major application of digital technology in the field of...

Problems solved by technology

However, the current model testing device has the following limitations: 1) For the building items to be tested, it cannot automatically give the testing results directly from the two perspectives of whether the information is complete and whether the information is correct; 2) The rules are described on the BIM model, resulting in Detecting different BIM models needs to re-modify the rule base, which is not easy to use

3) For the detection of the IFC file format of the building information model, it is difficult to deal with the model specification detection problem under the background of the integration of the building information model, geographic information system and infrastructure model in the smart city

There is no BIM model specification detection device with independent intellectual property rights in China
