Description

Technical Field

[0001] The present invention relates to the field of building information technology, and in particular to a system capable of automatically generating a building information model (BIM) and providing a collaborative editing function. Background Art

[0002] With the rapid advancement of the information age, software engineering technology is constantly moving towards a mature stage, and building information modeling (BIM) has come into being. It takes various relevant information data of construction projects as the cornerstone and carefully constructs a three-dimensional building model. This model accurately simulates and displays the actual properties and details of the building through the simulation technology of digital information, reflecting the comprehensiveness, relevance and consistency of information. BIM not only has a high degree of visualization, but also can achieve information coordination, simulation analysis, optimization and improvement, and drawing output. It covers all-round model data from macro to micro, from outdoor to indoor, and finally presents a computer graphics model that integrates multi-dimensional perspectives, diversified uses and efficient functions.

[0003] The traditional BIM model creation and editing process mainly relies on professional BIM software, such as AutoCAD, Revit, etc. Although these software are powerful, they have the following significant disadvantages:

[0004] 1. Highly dependent on professionals: The creation and editing of traditional BIM models requires professional BIM engineers or architects to operate, which leads to tight human resources and high labor costs.

[0005] 2. Low work efficiency: Since BIM models usually contain a large amount of building elements and attribute information, manually creating and editing these elements is not only time-consuming and labor-intensive, but also prone to errors.

[0006] 3. Difficulty in collaborative work: In scenarios where multi-professional teams work together, traditional BIM software often lacks an effective collaborative mechanism, leading to problems such as inconsistent data and confusing versions. This increases the complexity and risk of project management.

[0007] 4. Lack of automation and intelligence: Traditional BIM software lacks automation and intelligent support in the model generation and editing process. It cannot automatically generate models based on input data, nor can it perform intelligent analysis and optimization of models.

[0008] In response to the above problems, although some solutions for automatic generation and collaborative editing of BIM models have appeared on the market, these solutions often have problems such as single functionality, poor compatibility, and lack of usability, and cannot meet the construction industry's needs for efficient, intelligent, and collaborative BIM model creation and editing. Summary of the invention

[0009] The purpose of the present invention is to provide a building information model automatic generation and collaborative editing system to solve the problems raised in the above background technology.

[0010] To solve the above technical problems, the present invention provides a technical solution: a building information model automatic generation and collaborative editing system, including a front-end user interface, a back-end server, a core engine, and middleware;

[0011] The front-end user interface is a direct interface for users to interact with the system, including a graphical user interface (GUI) and a permission management module. The GUI is responsible for the import, visualization, editing and annotation of BIM models, providing users with an intuitive operation experience. The permission management module strictly controls the access and operation of BIM models and related data according to the user's role and permission level, ensuring the security and integrity of the data.

[0012] The back-end server serves as the data processing center of the system, including a data storage module, an API interface and a message queue module; the data storage module uses relational database or non-relational database technology to efficiently store and manage BIM models and related data, and supports rapid retrieval and update of data; the API interface provides a RESTful-style data interaction interface to achieve seamless data communication between the front-end user interface and the back-end server; the message queue module is used to implement real-time collaborative editing functions, and through the message queue mechanism, the user's editing operations are synchronized in real time to other collaborative editing users, ensuring data consistency and real-time performance during multi-person collaboration;

[0013] The core engine, as the core processing unit of the system, includes an automatic generation module and a collaborative editing module. The automatic generation module can automatically or semi-automatically generate BIM models based on preset rules or advanced machine learning algorithms, reducing the workload of users' manual modeling. The collaborative editing module is responsible for handling concurrent editing scenarios, and ensures that the consistency and integrity of the data are not affected when multiple people edit the BIM model at the same time through technical means such as locking mechanisms and version control.

[0014] The middleware serves as a bridge connecting the front-end user interface, back-end server and core engine, and includes a file processing module and a cloud service integration module; the file processing module supports the import and export of multiple BIM file formats, making it convenient for users to share and exchange BIM models between different software platforms; the cloud service integration module uses cloud computing technology to achieve cloud storage of BIM model data and efficient allocation of computing resources, thereby improving the scalability and flexibility of the system.

[0015] As a preferred solution, the graphical user interface is used for importing, visualizing, editing and annotating the model;

[0016] Through the GUI interface, users can easily import various BIM model files, and the system will instantly display the three-dimensional visualization of the model. Based on the visualization, users can edit the model, such as adjusting the model size, changing the material, adding or deleting components. At the same time, the GUI also supports annotation of the model, and users can add text, annotation or picture annotation information to the model to facilitate subsequent design review or construction guidance.

[0017] As a preferred solution, the authority management module first assigns corresponding authority levels to users according to their roles, which include designer, engineer, and project manager;

[0018] When a user logs into the system, the permission management module verifies the user's identity and role, and controls his access and operations to the BIM model and related data according to his permission level.

[0019] As a preferred solution, the data storage module uses relational database or non-relational database technology to design a reasonable database structure and index according to the characteristics and requirements of BIM model data;

[0020] The relational database is MySQL or PostgreSQL, and the non-relational database is MongoDB or Cassandra;

[0021] The data storage module is responsible for storing BIM models and component properties, material information, and annotation data in the database, and supports rapid retrieval and update operations of data to meet the system's requirements for real-time and accuracy of data.

[0022] As a preferred solution, the API interface is a RESTful data interaction interface, and the front-end user interface communicates with the back-end server through HTTP requests; the API interface receives requests sent by the front-end, and calls the corresponding back-end service for processing according to the type and parameters of the request; after processing, the API interface encapsulates the result data into JSON or XML format, and returns it to the front-end user interface for display or further processing.

[0023] As a preferred solution, the message queue module is used to implement real-time collaborative editing;

[0024] When a user performs an editing operation, the message queue module encapsulates the user's operation information into a message and sends it to the message queue; other collaborative editing users subscribe to the message queue to receive and process these messages in real time, thereby achieving real-time synchronous editing of the BIM model; at the same time, the message queue module also supports persistent storage and retry mechanisms for messages to ensure the reliability and integrity of the messages.

[0025] As a preferred solution, the automatic generation module automatically generates a BIM model based on a rule module and a machine learning algorithm module;

[0026] The rule module is defined according to the architectural design specifications, standards or the size and material information of commonly used components;

[0027] The machine learning algorithm module extracts the rules and features of model generation by learning a large amount of BIM model data, and generates a new BIM model accordingly;

[0028] The automatic generation module customizes and optimizes the generated model according to the user's needs and preferences.

[0029] As a preferred solution, the collaborative editing module is used to handle concurrent editing to ensure data consistency and version control;

[0030] Use locking mechanisms and version control technologies to handle concurrent editing scenarios;

[0031] When a user performs an editing operation, the collaborative editing module first checks whether the current model is locked by other users;

[0032] If it is not locked, the user is allowed to perform editing operations, and the operation information is recorded in the version control system;

[0033] If the model has been locked by other users, the user is prompted to wait or negotiate;

[0034] At the same time, the collaborative editing module also supports conflict detection and resolution mechanisms. When multiple users edit the same part of the model at the same time, it automatically detects and prompts users to resolve conflicts.

[0035] As a preferred solution, the file processing module supports the import and export of BIM files;

[0036] When a user needs to import a BIM model, the file processing module first parses the file format and extracts the model data and related attribute information; then, the data and information are stored in the database for subsequent operations; when a user needs to export a BIM model, the file processing module encapsulates the model data and related attribute information in the database into the corresponding file format according to the file format and parameters selected by the user, and saves it to the specified location.

[0037] As a preferred solution, the cloud service integration utilizes cloud computing technology to achieve cloud storage of BIM model data and efficient allocation of computing resources;

[0038] The cloud service integration module connects with the API interface of the cloud service provider to upload the BIM model data to the cloud storage service. At the same time, the cloud service integration module can also dynamically adjust the allocation and scheduling of computing resources according to the system load and user needs.

[0039] Increase computing resources during peak hours to improve system performance, and release computing resources during off-peak hours to reduce costs.

[0040] Compared with the prior art, the advantages of the present invention are: it can automatically generate a BIM model based on input data (such as CAD drawings, GIS data or text descriptions), greatly reducing the time and labor cost of manually creating models; through automated and intelligent means, it can quickly generate high-quality BIM models and improve overall work efficiency; it supports multiple users to edit BIM models at the same time, realizes real-time collaborative work, and avoids the problems of data inconsistency and version confusion; it has a built-in version control and conflict detection mechanism to ensure the consistency and integrity of data during the collaborative editing process; it can perform intelligent analysis on BIM models, such as energy consumption analysis, structural analysis, etc., and provide optimization suggestions to help users improve design solutions; according to the analysis results, users can adjust and optimize the BIM model to improve design quality and construction efficiency; it supports the import and export of multiple file formats, is compatible with multiple BIM software, and facilitates users to share and collaborate on models between different platforms; it provides an intuitive graphical user interface (GUI) to reduce the difficulty of operation, so that non-professionals can also use it easily; it provides a highly visualized BIM model display function, so that users can intuitively understand the structure and details of the building; it supports a full range of model data display from macro to micro, outdoor to indoor, to meet the diverse needs of users.
