Abstract

The invention provides a fusion system and method used between a GIM model and an IFC model, and the method comprises the steps: reading a GIM model file and an IFC model file in a power grid engineering model, and carrying out the integrity check; Respectively carrying out file analysis on the GIM model file and the IFC model file to obtain an analysis result, and storing the analysis result in aJSON or XML file form; Respectively establishing a mapping relation between the description schemes of the GIM model and the IFC model and the description scheme of the unified reference model, converting the mapping relation, and storing the mapping relation in a JSON or XML file form; Generating a plurality of spatial relationships by analyzing geometric data in the unified reference model; Andbased on multiple spatial relationships, performing difference comparison on the GIM conversion result and the IFC conversion result to obtain a version difference result. IFC and GIM models of multiple versions of one project in multiple stages of the life cycle are fused into the same unified reference model, convenience is provided for design and development of power grid projects, and the communication cost of the project is effectively saved.

Description

technical field [0001] The present invention relates to the technical field of building information modeling systems, in particular to a fusion system and method for GIM models and IFC models, and in particular to a system for fusing multi-version GIM models and IFC models of State Grid projects. Background technique [0002] The digitization of electric power engineering is a key factor supporting the smart grid. The popularization and application of BIM technology plays a vital role in the life cycle management of power grid engineering. Exchange engineering information to provide solutions to interoperability challenges. A major contribution of the application of BIM technology is to provide a unified data format. At present, there are mainly two data format standards, GIM and IFC, in the field of power transmission and transformation engineering in China. The goal of both is to create, store, update, and exchange building-related information throughout the life cycle o...
