Automatic Model Compliance Check Based On Ontology Technology In BIM Environment

BIM(Building Information Modeing)is the most favorable means to promote the development of informationization in China’s construction industry,and the industry is exploring the use of it,and the national policy is also vigorously promoting it.The way of inspection basically relies on manual inspection,and the quality recognition still stays in the stage of two-dimensional drawing review.For such inspection mode,it is easy to produce the problem of missing and wrong inspection,and it is difficult to check the 3D model quickly and accurately.Under the background of continuous and rapid development of China’s construction industry and rapid promotion of informationization,how to check the BIM model accurately and quickly has become an urgent problem to be solved.In this paper,based on the background of BIM technology,the automatic checking of BIM models according to the model compliance of ontology technology aims to solve the problem of how to check BIM models automatically and accurately and quickly.Translated with www.Deep L.com/Translator(free version)In this paper,we consider the arrival of IFC(Industry Foundation Classes),which is a common file format for BIM applications and has wide application value.Based on IFC and ontology technology,we study the automatic model compliance checking based on ontology technology in BIM environment.This research is used cross-industry to assist the current manual inspection of models,reduce the workload of inspectors,reduce the error of inspection work,and thus improve the efficiency of inspection.Firstly,this paper takes advantage of ontology technology in knowledge representation and semantic network application,etc.,and develops an ontology of building structural design codes based on the analysis of building structural codes,and elaborates on the method.Secondly,based on the above work,the code knowledge types applicable to the building structure model review rule construction among them are studied and determined according to the characteristics of the building structure design code provisions,and the applicable building structure design code knowledge is obtained,and the building structure design code knowledge is completed by constructing the SPARQL(SPARQL Protocol and RDF Query Language)query triad.The regularized representation of structural design codes is completed by constructing SPARQL(SPARQL Protocol and RDF Query Language)query triad.Again,the IFC and ontology formats and their respective expressions are studied,and the IFC-ontology conversion and ontology mapping are studied to create the instance ontology of the building structure model,and the instance ontology is supplemented by the self-programming.Finally,the whole process of automatic compliance checking of building structure model proposed in this paper is explained with examples and the feasibility of the method is verified with examples.
