Research On Automated Review Of Building Fire Drawings Based On BIM

Building fire drawings review refers to reviewing the fire protection drawings and related materials of building projects in accordance with fire industry standards,design specifications,etc.,so as to avoid hidden fire hazards in the building fire drawing process.Building fire drawings review is an important basis for fire protection work,and it is of great significance for ensuring the safety and property of people.At present,the fire drawings review mainly relies on manual review,and there are some problems such as low efficiency and missing items in the review process.Building information modeling(BIM)has become one of the most promising technologies in the field of construction and engineering with the development of modernization and informatization of the construction industry.The BIM model contains data information during the entire life cycle of the building.Applying the data expression and transformation capabilities and three-dimensional visualization characteristics of BIM technology to building fire drawings review can ensure the comprehensiveness and accuracy of the data,and can also provide a visual display scheme for building fire drawings review.The purpose of this paper is to achieve reviewing the building fire drawings automatically.The paper uses BIM and knowledge graph technology to propose an automated building fire drawings review method to solve the existing problems.The main research work is as follows:(1)The construction method of building fire knowledge graph is proposed.In this paper,the data structure and characteristics of the building fire code were studied,and the building fire knowledge graph was constructed through the steps of ontology construction,information extraction and knowledge storage.The method structured the data in the code and realized the semantic expression of building fire code knowledge.(2)The BIM data extraction and integration method for building fire drawings review is proposed.The paper studies a method for targeted classification extraction and integration of BIM data based on the fire knowledge graph network and IFC standards.This method realizes the transformation and analysis of multi-source heterogeneous BIM data,and completes the extraction and integration of basic information,geometric information and attribute information of model components related to review,providing a data basis for building fire drawings review.(3)The regulation and data matching method based on vector is proposed.The method researches the knowledge structure in the building fire knowledge graph and the structure of the BIM data,and the review vector set and model data vector set are constructed and matched to achieve automated review of building fire drawings.Based on the above theoretical research,the paper combined with WebGL and other related technologies to develop an automated building fire drawings review system based on BIM,which realizes the functions of automated fire drawings review and three-dimensional display of the results.The paper uses an actual model project to validate the feasibility and practicability of the method.And the experiments show that the proposed mothed meets the industry needs for comprehensiveness,efficiency and accuracy of fire drawings review.
