Problems solved by technology

However, the patent does not clarify how to construct the IFC geometric model converter and what specific conversion method is used to realize the conversion of non-IFC files
[0008] The Chinese invention patent application with application number CN201310042103.X and application publication number CN103970919A proposes a "data processing method for automatic building information modeling". Although it mentions format conversion of multiple survey data, it does not introduce how to convert
[0009] The Chinese invention patent application with application number CN201310205695.2 and application publication number CN103324475A proposes "BIM model rendering optimization system and method based on IFC standard". The IFC format is converted to the IFC standard format, but it does not introduce how to convert it

Embodiment 1

[0086] Such as figure 1 As shown, the IFC-based data interaction method of this embodiment includes:

[0087] The first step is to judge the type of data generated by BIM modeling software: if the data belongs to the BIM model structured data, go to the second step; if the data belongs to unstructured data, go to the third step;

[0088] Step 2, S1. Judging whether the data can be converted into IFC format data through the intermediate data format conversion method, if it can be transferred to S2, if not then transferred to S3;

[0089] S2. Convert the data into data in a preset intermediate data format, and then convert it into IFC format data; go to the fourth step;

[0090] S3. Using a preset data conversion plug-in program, the data is converted into IFC format data after parsing; go to the fourth step;

[0091] In S3, the data transformation plugin is:

[0092] S31. Analyzing the data into each component unit and the organizational relationship between each component u...

[0102] Interact the structured data generated by the Tekla modeling software according to the method of this embodiment, the specific process is as follows figure 2 shown. This process is a conversion process of the structured data data conversion plug-in.

[0103] Among them, the spatial structure analysis results of the data conversion plug-in program are as follows: image 3 Shown; the analysis and definition of the spatial structure is shown in the following code, some of which are as follows Figure 4 shown.

test example 2

[0118] The unstructured data generated by the Tekla modeling software is interacted according to the method of this embodiment, and the format conversion process is the third step of the method of this embodiment. The specific implementation examples are as follows:

[0119] A lightweight model file read-write interface for Tekla software (that is, the main program of the data conversion interface) is adopted. The interface uses Visual C++6.0 as the development tool and is based on the open source Openshell-based IFC parser.

[0120] The specific workflow of this interface is as follows: Figure 5 shown. First read the Tekla source file, traverse all parts and features and obtain the data of each feature, and then according to the IFC generator, impose constraints on the structural features for storage until the information reading is completed, complete the model creation, and save it as IFC format data.

[0121] Such as Image 6 As shown, taking a Tekla model of a steel tr...

Abstract

The present invention relates to an IFC-based data interaction method and a corresponding Web-BIM engineering information integration management system. The data interaction method comprises converting data, structured data or unstructured data, respectively into IFC format data according to a predetermined algorithm, and associating the data with a preset system database. The management system comprises a system database, and an IFC data interaction module, a GIS integration module, an information query module and a user management module which are respectively in communication with the system database. BIM-involved different data formats can be converted into IFC data formats, and the data interaction obstacle caused by unified data formats of BIM type modeling software in the prior art is overcome, thereby facilitating implementation of integration management of BIM project engineering data information.

Description

technical field [0001] The invention relates to an IFC-based data interaction method and a Web-BIM engineering information integrated management system using the method, belonging to the field of construction industry information technology. Background technique [0002] With the emergence of a large number of construction projects, the scale of engineering construction and the increasing complexity of projects, a large number of new large-scale tower building / construction machines and construction schemes have emerged. Faced with the challenge of no ready-made case reference, the construction unit’s previous working methods under the guidance of experience have gradually been unable to adapt to the trend of transformation from construction enterprises in the industry to management-oriented construction enterprises. The many characteristics of BIM (Building Information Modeling) technology enable its application to meet the requirements of transformation and upgrading of con...
