[0043] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0044] The model file processing method provided by the embodiments of the present application can be applied to a computer device, which can be a terminal or a server. The terminal can be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, Internet of Things devices, etc., and the specific terminal is not specifically limited herein. The server can be implemented by an independent server or a server cluster composed of multiple servers.

[0045] In an embodiment of the present application, as shown in Figure 1 A model file processing method is provided. Taking the server as an example, the method comprises the following steps:

[0046] Step 101: An initial BIM model file corresponding to a power grid device is obtained.

[0047] The initial BIM model file includes component files and attribute description files of each component in the power grid device. The BIM model file can be an RVT format source file or a 3DMAX format source file, and the specific format is not specifically limited herein.

[0048] Optionally, the server obtains the initial BIM model file in the following manner: receiving a sending request of a terminal to obtain the initial BIM model file, or obtaining the initial BIM model file stored in the cloud through networking, and the specific obtaining manner is not limited herein.

[0049] Step 102: According to each attribute description file, a target component with the same type as other components is determined.

[0050] Each attribute description file includes attribute information data of each component, such as spatial feature data, volume feature data, color feature data, material attribute data, etc., and the corresponding component can be determined through the attribute description file.

[0051] Optionally, the target component with the same type as other components in each component can be determined according to the spatial feature data, volume feature data, color feature data, or material attribute data of each attribute description file. In the embodiment of the present application, the target component with the same type as other components in each component can be determined according to the spatial feature data.

[0052] In a possible implementation manner, the target component with the same type as other components in each component can be determined by one-to-one comparison of the spatial feature data of each attribute description file with all components.

[0053] In a possible implementation manner, the target component with the same type as other components in each component can be determined by one-to-one comparison of the spatial feature data of each attribute description file with all components.

[0054] The component file is used to display the BIM model of each component, and the attribute description file has a corresponding relationship with the component file.

[0055] The component file is used to display the BIM model of each component, and the attribute description file has a corresponding relationship with the component file.

[0056] Optionally, the removal manner includes marking the target component with the same identifier, and removing the target component file according to the identifier.

[0057] Optionally, the removal manner includes marking the target component with the same identifier, and removing the target component file according to the identifier.

[0058] Optionally, the removal manner includes marking the target component with the same identifier, and removing the target component file according to the identifier.

[0059] It can be understood that the target component file is removed in order to keep only one of the repeated same components in the BIM model file, and the component files of the remaining same components are deleted, thereby reducing the memory consumption and improving the BIM model processing efficiency.

[0060] The above model file processing method first acquires an initial BIM model file corresponding to a power grid device,

[0061] The initial BIM model file includes component files and attribute description files of each component in the power grid device; secondly, the target component with the same type as other components in each component is determined according to each attribute description file; and finally, the target component file corresponding to the target component is removed from each component file to obtain the component file after removal.

[0062] The component file after being removed is used to form a target BIM model file with each attribute description file, so that the target BIM model corresponding to the target BIM model file takes the component file of other components as the target component file in the display process. Through the method, the same and repeated components in the BIM model can be removed, so as to reduce the memory occupied by the BIM model.

[0063] As described above, after obtaining each attribute description file, the target component with the same type as other components in each component needs to be determined according to each attribute description file. In an embodiment of the present application, as shown in Figure 2 A method for determining a target component is provided, which includes the following steps:

[0064] Step 201: For each component, the spatial feature data of the component is obtained according to the attribute description file of the component.

[0065] The spatial feature data includes a pointer reference, spatial coordinates, an inclination angle, etc.

[0066] Step 202: The spatial feature data of the component is compared with the spatial feature data of other components in each component for consistency.

[0067] Optionally, the consistency comparison can be one-to-one comparison of the spatial feature data of the component with other components in each component, so as to improve the accuracy of comparison; or the other components can be grouped, and different spatial feature data of each group is compared synchronously, and then the comparison is exchanged continuously, so as to improve the comparison rate. The specific comparison mode is not limited here.

[0068] Step 203: If the spatial feature data of the component is the same as the spatial feature data of other components, the component is determined as the target component.

[0069] It can be understood that the spatial feature data can represent the basic information of the component, so as to determine the same component. If the spatial feature data of the component is the same as the spatial feature data of other components, all the same components can be determined and used as the target component.

[0070] In the embodiment, the consistency of all components is compared through the attribute description file of the component, so as to determine the same component, improve the processing efficiency of the model, and lay a foundation for light processing and reducing the memory occupied by the model.

[0071] Further, after obtaining the removed component file, each file can be stored. In an embodiment of the present application, as shown in Figure 3 A data storage method is provided, which includes the following steps:

[0072] Step 301, according to the preset compression mode, respectively compress the component file after the elimination and each attribute description file to obtain the compressed component file and the compressed attribute description file.

[0073] Wherein, the preset compression mode can compress the file to a preset compression size, for example, the file can be compressed to one tenth of the original file, so as to save space and facilitate transmission.

[0074] Optionally, the preset compression size can be defaulted by the system, set by the technician, or randomly selected, and the specific preset compression size is not limited herein.

[0075] Step 302, store the compressed component file and the compressed attribute description file as the target BIM model file.

[0076] Wherein, in the embodiment of the application, the component file can adopt GLB format file, and the attribute description file can adopt JSON format file. For the GLB format component file, binary storage storage mode can be adopted, which has the advantages of small volume and high loading efficiency.

[0077] In the embodiment, by compressing and storing the component file after elimination and each attribute description file, the purpose of reducing the occupied memory space and improving the file transmission efficiency can be further achieved.

[0078] In addition, in order to facilitate the identification and classification processing of the component, the component identifier can be added in the file to facilitate the identification of the corresponding component. In an embodiment of the application, as shown in Figure 4 A method for adding component identifier is provided, which comprises the following steps:

[0079] Step 401, obtaining the component identifier corresponding to the target component.

[0080] Wherein, the component identifier can be an identifier determined according to the information of the component, an identifier added by the technician, or an identifier automatically generated by the system. In the embodiment of the application, it can be an identifier determined according to the information of the component.

[0081] Step 402, adding the component identifier to the target attribute file of the target component, and adding the component identifier to the component file of other components of the same type as the target component.

[0082] The target attribute file includes an attribute description file, the component identifier is added to the target attribute file of the target component, that is, the component identifier is added to the attribute description file of the target component, and the component identifier is added to the component file of other components of the same type as the target component. In subsequent operations, due to the existence of the same component identifier, the corresponding component file can be found through the attribute description file, so as to facilitate the identification of the corresponding component.

[0083] As described above, in one embodiment of the present application, as shown in Figure 5 A method for obtaining a component identifier is provided, and the method comprises the following steps:

[0084] Step 501, obtaining the component code and the component name corresponding to the target component, the component code including a component ID and a component geometric information character group.

[0085] The component ID refers to a 16-bit random unique code corresponding to each component.

[0086] The component geometric information character group can be determined by the geometric information data of the component through the information parameters such as the component corresponding accessor, buffer view, buffer, etc., and then the geometric information data is converted into the component geometric information character group through a preset program.

[0087] The component name can be determined in the form of unicode encoding according to the index number of the component, and then the component name in the form of unicode encoding is converted into Chinese characters through a preset program, so as to facilitate the identification of subsequent users.

[0088] Step 502, splicing the component code and the component name to obtain the component identifier.

[0089] It can be understood that the component identifier includes the component code and the component name.

[0090] In one possible implementation manner, after the component code and the component name are spliced, the spliced component code and the component name can be converted in the form of character group through a preset program to obtain the component identifier in the form of character group, so as to further reduce the memory occupation and improve the processing efficiency of the model.

[0091] In addition, in one embodiment of the present application, a method for displaying a target BIM model is also provided, and the method comprises: if a display instruction for the target BIM model is received, displaying the target BIM model according to the target BIM model file.

[0092] In the display process of the target component, a candidate component file including a component identifier is searched, and a display screen of the target component is rendered according to the candidate component file.

[0093] In a possible implementation, when a user has a demand for displaying a target BIM model, a terminal can send a display instruction to a server. After the server receives the display instruction for the target BIM model, the server returns a corresponding instruction, so that the terminal displays the target BIM model according to the target BIM model file. Since the same repeated components have been removed, it is not necessary to load too many redundant components, which greatly improves the display rate of the target BIM model and reduces the memory consumption.

[0094] In an embodiment of the present application, as shown in Figure 6 a model file processing method is provided, and the method comprises the following steps:

[0095] In step 601, an initial BIM model file corresponding to a power grid device is obtained.

[0096] In step 602, for each component, spatial feature data of the component is obtained according to an attribute description file of the component.

[0097] In step 603, the spatial feature data of the component is compared with spatial feature data of other components.

[0098] In step 604, if the spatial feature data of the component is the same as the spatial feature data of other components, the component is determined as a target component.

[0099] In step 605, a target component file corresponding to the target component is removed from each component file, to obtain a removed component file.

[0100] In step 606, the removed component file and each attribute description file are respectively compressed according to a preset compression mode, to obtain a compressed component file and a compressed attribute description file.

[0101] In step 607, the compressed component file and the compressed attribute description file are stored as a target BIM model file.

[0102] In step 608, if a display instruction for the target BIM model is received, the target BIM model is displayed according to the target BIM model file.

[0103] In addition, in an embodiment of the present application, as shown in Figure 7As shown, another model file processing flowchart is provided to briefly illustrate the model file processing method. First, the BIM model is parsed to identify all components in the BIM model. Then, the components are compared one by one. The same components are retained only one and the rest are removed. Finally, the file after the removal processing is compressed and stored.

[0104] Please continue to refer to Figure 8 For a comparison between the BIM model before and after the model file processing in an embodiment of the present application, as an example, it can be seen that before the processing, the components include main transformer 1, main transformer 2, main transformer 3, reactor 4 and reactor 5, a total of five components, corresponding to five component files. However, since main transformer 1, main transformer 2 and main transformer 3 are the same repeated components, and reactor 4 and reactor 5 are the same repeated components, in the model file processing, the same repeated component files are removed, which is equivalent to removing the same repeated components and retaining only one. After the processing, main transformer 1, main transformer 2 and main transformer 3 only retain the component file of one component, and reactor 4 and reactor 5 also only retain the component file of one component. Finally, the five components are reduced to two components, reducing the memory occupation.

[0105] In addition, please refer to Figure 9 For a flowchart of the processed component files and attribute description files in an embodiment of the present application, as an example, it can be seen that the original size of an RVT format electrical BIM model file is 270M. The model file processing and compression are performed after the file is divided into component files and attribute description files. Finally, the lightweight file size is 9M, greatly reducing the memory consumption.

[0106] It should be understood that although each step in the flowchart involved in each embodiment as described above is displayed in sequence according to the arrow, these steps are not necessarily executed in sequence according to the arrow. Unless otherwise stated herein, the execution of these steps has no strict sequence limitation, and these steps can be executed in other orders. Moreover, at least part of the steps in the flowchart involved in each embodiment as described above can include multiple steps or stages, which are not necessarily executed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be executed in rotation or alternation with at least part of other steps or steps or stages in other steps.
