[0042] Embodiment 1:

[0043] This embodiment provides a communication room BIM model structured conversion method, which can be applied to a corresponding BIM model structured conversion server, such as Figure 1 As shown, the method comprises the following steps:

[0044] S1. Acquire original BIM model data of the communication room, wherein the original BIM model data includes attribute information of each component and geometric information, material information and matrix information of each component.

[0045] In the specific implementation, the server first obtains the original BIM model data of the communication room, which includes the attribute information of each component and the geometric information, material information and matrix information of each component. The server can obtain the original BIM model data of the communication room by uploading local data or transmitting data online.

[0046] 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.

[0047] During the 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. It can be achieved by using polygon reduction, merging, simplification and other technologies, thereby reducing the complexity and rendering cost of the model. 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 the real-time rendering engine, such as fbx, gltf and other format files.

[0048] S3. Perform file format verification on the lightweight file to obtain a verification result.

[0049] During specific implementation, after the server obtains the lightweight file, it performs a file format check 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 check passes, otherwise, the file format check fails.

[0050] 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.

[0051] In specific implementation, when the file format verification is determined to be passed according to 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, ground, 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, room-divided 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.

[0052] 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.

[0053] In 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, wherein 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

[0054] Lightweight files Structured property table Structured Graphics Table Id AFG_ID Id AFG_FID name name Unique number coding Rack length long Rack width Width Rack height high Rack Model Rack Model Seat number Seat number vertex AFG_MESH Material AFG_MESH Location AFG_MESH

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

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

[0057] Floor: parse and extract the geometric information, material information and matrix information of floor 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 from the stair segment type and process the 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 these data into corresponding structured format data.

[0071] The structural 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 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 division components, and convert these data into corresponding structured format data.

[0077] When converting equipment in the computer room, the subordinate relationships of racks, frames, boards, and ports can be analyzed to facilitate the subsequent connection with the business and identify the corresponding relationships. At the same time, the position data can be generated according to the projection area of ​​the rack to facilitate the planning and design of the computer room in the future.

[0078] During the structured conversion process, if the original unstructured data lacks the corresponding data attributes, the conversion will fail. The following are some points that may cause the conversion to fail during the actual conversion process: 1. The rack must contain the model field and cannot be empty; 2. The frame must contain the model field and cannot be empty. The frame must have an installation height so that it can be placed inside the rack; 3. The board must contain the model field and the relationship data with the slot in the frame. Otherwise, the board cannot be placed in the frame; 4. The business status field of the port cannot be empty. The port is currently modeled according to the business status; 5. The connection device and virtual device must contain the 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] In the specific implementation, the server preloads the structurally converted auxiliary facilities and equipment in the computer room and presents the results. In order to improve the loading efficiency during the preloading process, the LOD (multi-level detail representation) method can be used to preload each component to accelerate the rendering efficiency. The user sends an effect confirmation instruction to the server based on the presentation effect.

[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] The method of this embodiment can realize an efficient and controllable structural conversion process of the communication room BIM model, and can take into account the comprehensive optimization of the minimum triangular faces after lightweighting and the consistency of the original BIM model. Based on the results after lightweighting, the method decouples layer by layer to realize the componentized model description, and can dynamically maintain and update the equipment according to the componentized BIM model data, which is conducive to the full life cycle management and maintenance of equipment in the communication field station scene.
