Problems solved by technology

[0003] At this stage, when conducting safety inspections on hidden facilities of buildings, on the one hand, with the increase of the service life of the buildings and the frequent replacement of personnel, the information of the buildings in the design and construction phase is faced with the situation that less and less people know, and the related facilities are also faced with On the other hand, the traditional method of safety inspection of hidden facilities in buildings based on design and construction drawings has high requirements on the ability of staff to understand and use drawings, which is prone to misreading and other situations, and is inconvenient. When the safety inspection work is carried out without the drawings, a large number of missed checks, wrong checks, wrong repairs and other problems will be caused, which will bring great harm to the lives and property safety of the owners and staff

Embodiment Construction

[0027] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings, but they do not constitute a limitation to the present invention, and are only examples. At the same time, the advantages of the present invention are clearer and easier to understand through the description.

[0028] Such as figure 1 As shown, taking the underground pipeline BIM data produced by Revit as an example, the safety inspection of the building's underground pipeline facilities based on 3DGIS+BIM is carried out:

[0029] Step 1: Convert the underground pipeline BIM data produced by Revit to IFC format

[0030] Open the BIM data file in Revit software, select the export IFC function, and convert the BIM data to IFC format;

[0031] Step 2: Perform CityGML semantic conversion on the converted IFC data

[0032] According to the constructed semantic conversion library of BIM and 3DGIS (such as figure 2 shown), convert the IFC data expor...

Abstract

The invention discloses a 3DGIS+BIM-based safety detection method for hidden facilities of buildings. It includes the following steps: building a semantic conversion library between BIM and 3DGIS; BIM data preprocessing; loading the converted BIM data to the 3DGIS mobile terminal; designing QR codes for augmented reality security detection of important parts of buildings; building hidden facility security detection. The invention has the advantages of improving the safety detection efficiency of building concealed facilities and having strong versatility.

Description

technical field [0001] The invention relates to a safety detection method of a building concealed facility, more specifically, it is a safety detection method of a building concealed facility based on 3DGIS+BIM. More specifically, it is a security detection method for building hidden facilities based on 3DGIS, BIM and AR technology. Background technique [0002] In the entire life cycle of a building, the time period for building operation and maintenance is the longest. At present, BIM is used more in the planning, design and construction stages, and less in the operation and maintenance stage. In order to avoid the production of BIM data After the completion of the project, it will become a new data fossil, integrate BIM and 3DGIS, use the 3D visualization and 2D spatial analysis capabilities of GIS, and give full play to the potential application value of BIM in the operation and maintenance stage, so that the data can not only be managed, but also use it. [0003] At t...
