The specific structural and functional details disclosed herein are merely intended to describe exemplary embodiments of the present invention. However, the present invention may be embodied in a variety of alternative forms, and should not be construed as being limited to the embodiments set forth herein.

For example, it can mean a fixed connection, a detachable connection, or an integral connection; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in the embodiments based on specific circumstances.

[0042] In the following description, certain details are provided to facilitate a complete understanding of the example embodiments. However, one of ordinary skill in the art will appreciate that the example embodiments can be practiced without these specific details. For example, a system may be shown in a block diagram to avoid obscuring the example with unnecessary detail.

[0043] Example 1:

[0044] This embodiment provides a method for structural conversion of a BIM model of a communication room, which can be applied to a corresponding BIM model structural conversion server. As shown in FIG1 , the method includes the following steps:

[0045] S1. Acquire original BIM model data of the communication room, where the original BIM model data includes attribute information of each component as well as geometric information, material information, and matrix information of each component.

[0046] During implementation, the server first obtains the original BIM model data of the communication room. The original BIM model data includes the attribute information of each component as well as its geometry, material information, and matrix information. The server can obtain the original BIM model data of the communication room by uploading local data or transmitting it online.

[0047] S2. Import the original BIM model data into the lightweight engine, and perform lightweight processing on the original BIM model data based on the lightweight engine to obtain a lightweight file.

[0048] During specific implementation, the server imports the original BIM model data into the lightweight engine, and performs lightweight processing on the original BIM model data based on the lightweight engine, including geometric information simplification and material information compression processing, to obtain lightweight BIM model data. Geometric information simplification is to simplify the geometric information of BIM model components to reduce the number and complexity of polygons. This can be achieved using polygon reduction, merging, simplification and other technologies, thereby reducing the complexity of the model and rendering costs. Material information compression is to compress and optimize the material map of the model to reduce the size of the texture file and improve processing performance. The lightweight BIM model data is then exported as a lightweight file suitable for real-time rendering engines, such as fbx, gltf and other format files.

[0049] S3. Perform file format verification on the lightweight file to obtain a verification result.

[0050] During specific implementation, after the server obtains the lightweight file, it performs file format verification on the lightweight file. It first determines the file format of the lightweight file and compares the file format of the lightweight file with the set lightweight format (such as gltf format or a custom lightweight format). If the file format of the lightweight file is consistent with the set lightweight format, the file format verification passes; otherwise, the file format verification fails.

[0051] S4. When it is determined that the file format verification has passed according to the verification result, each component in the lightweight file is classified according to the attribute information of each component.

[0052] During specific implementation, when the file format verification is determined to be passed based on the verification results, the server classifies the components in the lightweight file according to the attribute information of each component, and each component is classified as ancillary facilities of the computer room or equipment in the computer room. Ancillary facilities of the computer room include: exterior walls, floor slabs, floors, windows, columns, stairs, curtain wall panels, platforms, handrails, top handrails, building floors, roofs, terrain, stairs, fire extinguishers, etc. Equipment in the computer room includes: racks, frames, boards, ports, indoor equipment, etc. Taking the rack as an example, in the lightweight file, the corresponding information of the rack may include ID, name, unique number, rack length, rack width, rack height, rack model, machine position number, vertex, material, position, etc.

[0053] S5. Perform structured conversion processing on the components completed in each classification in the lightweight file according to the preset structured model mapping relationship table, parse and extract the geometric information, material information and matrix information of the components completed in each classification and convert them into structured format data.

[0054] During specific implementation, after the classification of each component in the lightweight file is completed, the server will perform structured conversion processing on each classified component in the lightweight file according to the preset structured model mapping relationship table, parse and extract the geometric information, material information and matrix information of each classified component and convert them into structured format data. The geometric information includes vertex information, the material information includes color, texture and transparency information, and the matrix information includes position transformation information, rotation transformation information and scaling transformation information. The structured model mapping relationship table includes a structured attribute table and a structured graphics table. For example, taking the rack as an example, the corresponding structured model mapping relationship table content is shown in the following table

[0055] The structural conversion process for the corresponding computer room ancillary facilities is as follows:

[0056] Exterior wall: parse and extract the geometric information, material information and matrix information of the exterior wall components, and convert these data into corresponding structured format data;

[0057] Floor slab: parse and extract the geometric information, material information and matrix information of floor slab components, and convert these data into corresponding structured format data;

[0058] Ground: parse and extract the geometric information, material information and matrix information of ground components, and convert these data into corresponding structured format data;

[0059] Windows: Parse and extract the geometric information, material information, and matrix information of window components, and convert these data into corresponding structured format data;

[0060] Column: parse and extract the geometric information, material information and matrix information of the column components, and convert these data into corresponding structured format data;

[0061] Stairs: parse and extract the geometric information, material information, and matrix information of stair components, and convert these data into corresponding structured format data;

[0062] Curtain wall panels: parse and extract the geometric information, material information, and matrix information of curtain wall panel components, and convert these data into corresponding structured format data;

[0063] Platform: parse and extract the geometric information, material information and matrix information of platform components, and convert these data into corresponding structured format data;

[0064] Railings: Parse and extract the geometric information, material information, and matrix information of railing components, and convert these data into corresponding structured format data;

[0065] Top handrail: parse and extract the geometric information, material information and matrix information of the top handrail components, and convert these data into corresponding structured format data;

[0066] Building floor: parse and extract the geometric information, material information and matrix information of building floor components, and convert these data into corresponding structured format data;

[0067] Roof: parse and extract the geometric information, material information and matrix information of the roof components, and convert these data into corresponding structured format data;

[0068] Terrain: parse and extract the geometric information, material information, and matrix information of terrain components, and convert these data into corresponding structured format data;

[0069] Stair segment: Parse and extract the geometric information, material information, and matrix information of the stair segment type and process this data into a structured format;

[0070] Fire extinguisher: Parse and extract the geometric information, material information, and matrix information of the fire extinguisher components, and convert this data into corresponding structured format data.

[0071] The structured conversion process for the equipment in the corresponding computer room is as follows:

[0072] Rack: Parse and extract the geometric information, material information, and matrix information of the rack components, and convert these data into corresponding structured format data;

[0073] Frame: parse and extract the geometric information, material information, and matrix information of the frame components, and convert these data into corresponding structured format data;

[0074] Board: parse and extract the geometric information, material information and matrix information of the board components, and convert these data into corresponding structured format data;

[0075] Port: parse and extract the geometric information, material information and matrix information of the port component, and convert these data into corresponding structured format data;

[0076] Room division: parse and extract the geometric information, material information and matrix information of room components, and convert these data into corresponding structured format data.

[0077] When converting equipment within a computer room, the relationships between racks, chassis, boards, and ports can be analyzed to facilitate subsequent business integration and identify corresponding relationships. Furthermore, location data can be generated based on the projected area of ​​the racks, facilitating later computer room planning and design.

[0078] During the structured conversion process, if the original unstructured data lacks the corresponding data attributes, the conversion will fail. The following points should be noted during the actual conversion process and may cause conversion failure: 1. The rack must contain a model field and cannot be empty. 2. The chassis must contain a model field and cannot be empty. The chassis must have a certain installation height to be able to be placed inside the rack. 3. The board must contain a model field and data related to the slots in the chassis. Otherwise, the board cannot be placed in the chassis. 4. The port's service status field cannot be empty. Ports are currently modeled based on service status. 5. Connected devices and virtual devices must contain a model field.

[0079] S6. Preload and display the effects of each component based on the structured format data of each component, and obtain the user's effect confirmation instruction.

[0080] During implementation, the server preloads the converted computer room facilities and equipment and presents the results. To improve loading efficiency, LOD (Level of Detail) can be used to preload components, accelerating rendering. Based on the rendering results, the user sends a confirmation command to the server.

[0081] S7. Save the structured format data of each component according to the effect confirmation instruction.

[0082] During specific implementation, the server saves the structured format data of each component to the database according to the effect confirmation instruction.

[0083] This embodiment method enables an efficient and controllable structural conversion process for the BIM model of a communications room, achieving a comprehensive optimization by balancing the minimum number of triangular faces after lightweighting with consistency with the original BIM model. Based on the lightweighting results, the method decouples the model layer by layer to achieve a componentized model description. Dynamic equipment maintenance and updates can be performed based on the componentized BIM model data, facilitating the full lifecycle management and maintenance of equipment within communications field stations.
