Description

Technical Field

[0001] This invention relates to the field of BIM technology applications, specifically a BIM material retrieval system based on a B / S structure. Background Technology

[0002] In the early stages of subway construction, BIM technology is often used for construction management to address issues such as material waste, on-site processing, and rework related to cable trays. This technology can identify and optimize potential problems in the model in advance, extract materials based on the BIM model, accurately perform quantity calculations, significantly save time on manual material handling and calculation, effectively avoid measurement errors that are prone to occur in traditional manual material handling, and achieve effective control of construction costs.

[0003] Currently, BIM material retrieval technology still has significant shortcomings in practical applications. First, the material retrieval process is cumbersome, requiring multiple steps such as model fine-tuning, obtaining numbers in Dynamo, adjusting the schedule, and editing Excel files. Although it is more efficient and accurate than manual drawing material retrieval, the overall process still has considerable room for optimization. Second, viewing BIM models relies on Revit and specialized BIM viewing software, which is generally not available to on-site technicians. Viewing the model requires repeated communication and coordination with BIM personnel, resulting in wasted construction time and directly impacting on-site work efficiency, which needs improvement.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1 A BIM material retrieval system based on a B / S structure includes:

[0022] The front-end presentation layer is used to realize lightweight BIM 3D rendering and interactive operations, send operation requests to the back-end service layer and receive the returned results for display;

[0023] The backend service layer is used to receive operation requests from the frontend presentation layer, execute business logic processing, interface scheduling and permission management, initiate data read and write to the data storage layer, and call the model parsing and metadata extraction services provided by the core technology support layer.

[0024] The data storage layer is used to store and retrieve data according to the instructions of the backend service layer, and return the results to the backend service layer.

[0025] The core technology support layer is used to parse BIM files and extract model material metadata according to the calls from the backend service layer, and return the results to the backend service layer.

[0026] The front-end presentation layer is connected to the back-end service layer via a network interface and a data protocol. The back-end service layer is connected to the data storage layer via a network interface and a data protocol. The back-end service layer is connected to the core technology support layer via a network interface and a data protocol.

[0027] In a specific embodiment, please refer to Figure 1 In the early stages of subway construction, on-site personnel initiate model viewing and material retrieval requests through the front-end display layer. These requests are transmitted to the back-end service layer via a network interface. The back-end service layer then manages permissions and business logic, retrieving model and user data from the data storage layer. Simultaneously, it calls the core technology support layer to parse BIM files and extract material metadata. The data storage layer and the core technology support layer then send the results back to the back-end service layer. After processing, the back-end layer sends the results back to the front-end display layer, completing lightweight model viewing and automatic material retrieval. This solves the problems of cumbersome traditional processes and the lack of dedicated software for model viewing on-site.

[0028] In this embodiment: Please refer to Figure 1 The front-end presentation layer uses the Bootstrap framework to build a responsive user interface that is compatible with multiple terminals; it integrates the WebGL graphics engine to achieve lightweight 3D visualization rendering of BIM models.

[0029] The front end uses the Bootstrap framework to adapt to multiple terminals and integrates the WebGL graphics engine to achieve lightweight rendering of BIM models, which can meet the viewing needs of different equipment on the construction site and solve the pain points of slow loading and complicated operation of traditional BIM models.

[0030] In this embodiment: Please refer to Figure 1 The backend service layer is built on the Java Spring Boot framework to provide (core) services, which handle business logic, API scheduling, and access control.

[0031] The backend is built on the Java Spring Boot framework, which can stably handle business logic, interface scheduling and permission management, ensuring stable and easily scalable system operation and supporting efficient operation of the entire material feeding process.

[0032] In this embodiment: Please refer to Figure 1 The data storage layer uses a MySQL database to store the bill of materials, model metadata, user information, and material delivery records, and interacts bidirectionally with the backend service layer.

[0033] Using a MySQL database, it can securely store information such as material lists and model metadata, and enable bidirectional interaction with the backend to achieve fast data reading and writing, facilitating material requisition data traceability and management.

[0034] In this embodiment: Please refer to Figure 1 The core technology support layer integrates Model Derivative model conversion service and connects to the backend service layer to realize BIM file parsing and material metadata extraction.

[0035] It accurately analyzes BIM files and extracts material metadata, replacing manual extraction steps, avoiding omissions and miscalculations in material selection, and improving the accuracy of material selection.

[0036] In this embodiment: Please refer to Figure 1 The system integrates a DeepSeek distilled version AI large model, which is used to determine whether an instruction should be executed and to answer BIM-related questions.

[0037] Integrating DeepSeek Distilled Edition AI large model enhances the system's intelligence level and simplifies on-site personnel's operation and consultation processes.

[0038] In this embodiment: Please refer to Figure 1 The system integrates the entire process of model conversion, lightweight BIM model viewing, metadata extraction, and automatic material requisition, and generates Excel files and exports data via Java.

[0039] By automatically generating and exporting Excel files using Java, the material handling process is simplified, standardized, and construction material handling efficiency is improved.

[0040] This invention effectively solves the problems of cumbersome material requisition processes and reliance on dedicated software for viewing on-site models in traditional BIM systems by coordinating a front-end presentation layer, a back-end service layer, a data storage layer, and a core technology support layer. The system achieves lightweight rendering of BIM models, automatic extraction of metadata, and accurate material calculation, all without the need for client installation and can be used conveniently across platforms. Stable interaction between each layer ensures accurate data transmission, significantly simplifies material requisition steps, improves quantity calculation efficiency, reduces construction communication costs, promotes the standardization of material requisition processes, and significantly improves construction collaboration and project management efficiency.

Therefore, the embodiments should be considered in all respects as exemplary and not restrictive.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity.
