Description
Technical Field
The invention relates to the technical field of building information model systems, in particular to a system and a method for fusing a GIM (general information model) model and an IFC (information model), and particularly relates to a system for fusing a national grid engineering multi-version GIM model and an IFC model.
Background
The digitization of the power engineering is a key element for supporting the smart grid, the popularization and application of the BIM technology play a vital role in the whole life cycle management of the power grid engineering, and a solution is provided for exchanging engineering information among different benefit subjects, stages and different specialties involved in the engineering to solve the problem of interoperability. One of the major contributions of BIM technology applications is to provide a unified data format. At present, two data format standards of GIM and IFC mainly exist in the field of power transmission and transformation engineering of a Chinese power grid. Both are aimed at creating, storing, updating, and exchanging building-related information throughout the life cycle of the electric transmission and transformation project, but there are large differences in data formats.
Buildings, structures, support structures and fire fighting and cooling systems in power transmission and transformation engineering are often represented in IFC format. The IFC format is a computer interpretable, public, structured, object-oriented engineering model information exchange format intended to provide the construction industry with an intermediate data standard that is independent of any specific software system, and can be used to describe product data throughout the life cycle of a construction project. The IFC Schema (IFC description Schema) is the main content of the IFC standard, and is composed of 4 levels of a resource layer, a core layer, a sharing layer and a field layer, and provides specifications of description and definition of various information processed by the construction engineering implementation process. The IFC Schema is described in the Express language defined in ISO 10303-11.
The GIM technology is an engineering data exchange standard in a national network system, which is provided by China national network companies for the reference of BIM technology and aims at the characteristics of power grid engineering. The GIM three-dimensional engineering model comprises a physical model and a logic model, wherein the physical model describes the collective shapes of components of engineering equipment and materials and non-graphic attribute information of the components, and the logic model expresses the architecture and connection and control logic of a system which are vital to a power grid system. The model comprises component graphs and corresponding attribute information at different levels.
Because the data description and storage methods in the GIM format and the IFC format are obviously different, a fusion method for fusing the two data formats needs to be provided, so that a database compatible with the two data formats is provided for a national network system, convenience is provided for different businesses and users to access the BIM information of the power transmission and transformation project, and meanwhile, analysis of a related project model is ensured, such as clearance analysis between a charged component and an uncharged component, and the two data formats can be spanned.
