It can be understood that the target component file is removed, so that only one repeated identical component in the BIM model file is reserved, and component files of other identical components are deleted, thereby reducing memory consumption and improving BIM model processing efficiency.

The model file processing method comprises the steps of firstly, obtaining an initial BIM model file corresponding to power grid equipment,

the initial BIM file comprises a component file and an attribute description file of each component in the power grid equipment; secondly, determining target components with the same types as other components in the components according to the attribute description files; finally, eliminating the target component files corresponding to the target components from the component files to obtain the component text after elimination

As described above, in one embodiment of the present application, as shown in fig. 5, there is provided a method of acquiring a component identifier, the method including the steps of:

step 501, a component code and a component name corresponding to a target component are obtained, wherein the component code comprises a component ID and a component geometric information character set.

Wherein, the component ID refers to a 16-bit random unique code corresponding to each component.

The component geometric information character set can firstly determine the geometric information data of the component through the corresponding accessor, bufferview, buffer information parameters of the component, and then convert the geometric information data into the component geometric information character set through a preset program.

Step 502, performing splicing processing on the component codes and the component names to obtain component identifiers.

In addition, in an embodiment of the present application, as shown in fig. 7, another flow chart of model file processing is provided, so that a simple and exemplary description is made on a model file processing method, firstly, the BIM model is parsed, all components in the BIM model are identified, then, a comparison is performed on the components, only one component remains, the rest components are removed, and finally, the files after the removal processing are compressed and stored.

With continued reference to fig. 8, in an embodiment of the present application, a comparison between the before and after model file processing of the BIM model is shown, and it can be seen that, before the processing, the components include five components including main transformer 1, main transformer 2, main transformer 3, reactor 4 and reactor 5, and the five components correspond to the five component files, but because main transformer 1, main transformer 2 and main transformer 3 are identical repeated components, reactor 4 and reactor 5 are identical repeated components, in the processing of the model file, the identical repeated component files are removed, which is equivalent to removing the identical repeated components, only one component file is reserved for main transformer 1 and main transformer 3, only one component file is reserved for main transformer 1 and reactor 4 and reactor 5, and finally, the five components are reduced to two components, thereby reducing the occupied memory.

In addition, please refer to fig. 9, which is a schematic flow chart of the processing of the component files and the attribute description files in an embodiment of the present application, it can be seen that an electric BIM model file in RVT format has an original size of 270M, and is divided into the component files and the attribute description files, and the model files are processed and compressed, so that a light file size of 9M is obtained, which greatly reduces the memory consumption.
