and S11, acquiring the BIM to be inspected and the model database file corresponding to the BIM to be inspected.
The BIM model to be examined is a three-dimensional model generated based on three-dimensional building design software. Different BIM models all have corresponding model database files. The electronic equipment can respond to the uploading operation of the BIM to be inspected by the user, acquire the BIM to be inspected, analyze the BIM to be inspected and obtain the model database file corresponding to the BIM to be inspected.
And S12, converting the model database file into a standard database file.
And the standard database file meets the database file which can be identified by the examination system, and the electronic equipment performs data conversion according to a certain conversion standard after acquiring the model database file corresponding to the BIM model to be examined, and converts the model database file into the standard database file which can be identified by the examination system. In particular, the electronic device may convert the model database file into a standard database file via a model conversion storage tool.
And S13, performing compliance examination on the standard database file to obtain a compliance examination result.
The electronic device checks the model data contained in the standard database file to determine whether the standard database file passes compliance checks. Specifically, compliance review includes: clear height check, quantity check, spatial intersection, distance check, spatial adjacency, color requirement, etc. And obtaining a compliance examination result corresponding to the BIM model to be examined by means of numerical value comparison, graph three-dimensional body judgment, coordinate data comparison calculation and the like, as shown in FIG. 7.
In the checking method for the BIM model provided in this embodiment, the model database file is converted into the standard database file by obtaining the to-be-checked BIM model and the model database file corresponding to the to-be-checked BIM model, and compliance checking is performed on the standard database file to obtain a compliance checking result. The method avoids the missing items of manual examination, improves the examination efficiency and improves the accuracy of the examination result.
In this embodiment, a checking method of a BIM model is provided, which can be used in electronic devices, such as a mobile phone, a tablet computer, a computer, etc., fig. 2 is a flowchart of the checking method of the BIM model according to the embodiment of the present invention, and as shown in fig. 2, the flowchart includes the following steps:
and S21, acquiring the BIM to be inspected and the model database file corresponding to the BIM to be inspected.
Specifically, the step S21 may include:
and S211, responding to the uploading instruction of the BIM model to be inspected, and acquiring the BIM model to be inspected.
The uploading instruction is input into the electronic equipment by a user, and specifically, the user can drag the BIM model to be inspected into the inspection system through a mouse; for the electronic device with the touch screen, the user can drag the BIM model to be examined into the examination system through the touch screen. Accordingly, the electronic device can respond to the uploading instruction of the to-be-inspected BIM model, and acquire the to-be-inspected BIM model uploaded to the electronic device inspection system. The BIM model to be checked can be stored in the local of the electronic equipment or can be stored in a U disk, and when the checking is needed, a user can connect the U disk with the electronic equipment so as to copy the BIM model to be checked to the local of the electronic equipment.

And the electronic equipment matches the analyzed graphic information with the analyzed text information, constructs a mapping corresponding relation between the graphic information and the text information, and determines a corresponding model database file according to the mapping corresponding relation between the graphic information and the text information.
And S22, converting the model database file into a standard database file.
Specifically, the step S22 may include:
s221, obtaining a conversion standard of the database file.
The conversion criteria are data composition criteria in the database file. The electronic device may query field information corresponding to the review system, such as semantic layer fields, feature layer fields, geometry layer fields, and network layer fields, to determine the data format corresponding to the current review system. Taking the WIFC standard as an example, the WIFC data standard is formed by adding service fields such as a business type, a component code, a space code and the like to the data composition of the IFC data standard.
S222, converting the model database file into a standard database file according to the conversion standard.
And the electronic equipment converts the model data file according to the conversion standard to obtain a standard database file meeting the requirements of the current examination system. For example, the electronic device may convert a model database file of the BIM model generated by Revit/ArchiCAD into a standard database file satisfying the WIFC data format using a model conversion storage tool, thereby freeing software from constraints on the database file.
And S23, performing compliance examination on the standard database file to obtain a compliance examination result. For a detailed description, reference is made to the related description of the above embodiments, which are not repeated herein.
