Graph-model consistency examination method and system based on knowledge graph, terminal and medium

Abstract

The invention provides a graph-model consistency examination method and system based on a knowledge graph, and the method comprises the steps: building a drawing body according to the structural information of a drawing; establishing a model ontology from a BIM model file; carrying out semantic fusion on the drawing ontology and the model ontology to form a graph-model fusion knowledge graph; and extracting related review points from the graph-model fusion knowledge graph, and completing consistency review. Meanwhile, the invention provides a corresponding terminal and a computer storage medium. According to the method, the overall conception that information is extracted from the building model and the design drawing file to form the knowledge graph and then consistency review is conducted is adopted, labeling information in the design drawing can be accurately extracted, attribute information of all components is included, and the labeling information is accurately compared with information in the building model; in the examination result, an examination result can be given according to the component type.

Description

technical field [0001] The present invention relates to a graph-model consistency review technology in the engineering field, in particular to a graph-model consistency review method based on a knowledge map. Background technique [0002] Since 2013, the Ministry of Housing and Urban-Rural Development of my country has successively promulgated "Guiding Opinions on Soliciting and Recommending the Application of BIM Technology in the Construction Field (Draft for Comment)" (2013), "Several Opinions on Promoting the Development and Reform of the Construction Industry" (2014) , "Guiding Opinions on Promoting Building Information Modeling" (2015), "2016-2020 Construction Industry Informatization Development Outline" (2016), "Building Information Modeling Construction Application Standards" (2018) and a series of guiding opinions to promote The application of BIM (Building Information Modeling) technology in architectural design, construction management and other fields. At the sam...

AI Technical Summary

Problems solved by technology

The number of projects is large, and the drawings and models of a large number of projects need to be reviewed by technicians, and the workload is very heavy

[0005] 2. There are many review points, and the approval is difficult

The review content includes construction, structure, HVAC, water supply and drainage, electrical and other different majors. The components and equipment of each major are reviewed one by one. While the workload is heavy, it is also extremely prone to leaks and mistakes. The review pressure of technicians very big

[0006] 3. There are still a lot of repetitive and redundant work in the review process, and the review efficiency is low

[0010] 1. Directly using artificial intelligence technology to extract drawing information has a low accuracy rate and does not meet the review requirements of construction projects;

[0011] 2. The information of the 3D model and the data expression structure of the drawing information are different, and it is impossible to directly apply artificial intelligence technology to complete the comparison of information consistency

The idea adopted by this method is based on the comparison of the main images of points and lines, which cannot guarantee that the labeling information in the design drawing is consistent with the model, and for the design drawing, the labeling information of components is also a very important parameter

[0015] At present, there is no description or report of the similar technology of the present invention, and no similar data at home and abroad have been collected yet.
