Engine device and method for data integration and exchange of building information mode based on IFC (industry foundation classes) standards

Abstract

The invention belongs to the technical field of information of the building industry, and provides an engine device and a method for data integration and exchange of building information mode based on IFC (industry foundation classes) standards, which are used for creating and applying a building information model (BIM). The method is based on a BIM database created on the basis of the IFC standards and a relational database, and BIM resolution in an IFC format, conversion of building information in non-IFC formats, extraction and integration of BIM submodels and storage, exchange and access control of BIM data are realized. The engine device comprises an IFC entity library, an IFC file resolver, an IFC geometric model converter, a Project-IFC converter, a BIM submodel integrator, a BIM submodel extractor, a data access controller, a BIM data storage device, a BIM data extractor, an IFC file generator and the like. The building information model data integration and exchange engine device and the method support conversion of BIM data in various formats, and BIM data integration and exchange oriented to various stages of the life cycle of a building or different applications can be realized. In addition, BIM data integration and exchange efficiency is effectively improved by the aid of data batch processing technology.

Description

technical field [0001] The invention belongs to the field of construction information technology, aims to solve the creation and application of building information model (Building Information Model, BIM), specifically relates to a kind of building information model based on IFC standard and relational database (Oracle, Microsoft SQLServer and MySQL, etc.) Based on the BIM database, it realizes the building information model data integration and exchange engine device and method of IFC format BIM model analysis, non-IFC format building information conversion, BIM sub-model extraction and integration, BIM data storage, exchange and BIM data access control. technical background [0002] Building information model is an engineering data model based on three-dimensional digital technology that integrates various relevant information of construction projects, and is a digital expression of the entity and functional characteristics of engineering project facilities. A complete inf...

Problems solved by technology

[0008] 1. Unable to integrate and exchange data with related BIM software from other software suppliers;

[0009] 2. Unable to perform version control;

[0010] 3. It is difficult to support multi-user collaborative work and simultaneous modification;

[0011] 4. It is difficult to finely control data access rights;

[0012] 5. Does not support the integration and exchange of BIM sub-models

[0014] 1. Unable to perform version control;

[0015] 2. It cannot support multi-user collaborative work and synchronous modification;

[0016] 3. Only supports linear workflow;

[0017] 4. It is difficult to finely control data access rights;

[0018] 5. Due to differences in the understanding of the IFC standard by different applications, it is easy to cause data loss;

[0019] 6. Does not support the integration and exchange of BIM sub-models;

[0020] 7. With the deepening of the design or the increase of the project scale, the IFC files will increase massively, and the speed and efficiency of information exchange will become the bottleneck problem to be solved urgently

The existing BIM server stores the BIM data (IFC files) submitted in different stages or different applications separately, that is, one project forms multiple models, and cannot form a complete model

[0031] 2. Low data extraction efficiency

On the one hand, it is because of the need to query and extract data from multiple models, and on the other hand, data batch processing technology is not used

[0032] 3. BIM sub-model definition and representation methods are not provided
