Description

Technical Field

[0001] This invention relates to the field of design technology for the refinement and finalization of three-dimensional models of engineering targets, specifically to a method and system for the refinement and finalization of three-dimensional models of engineering targets. Background Technology

[0002] Over the past 20 years, with the development of fundamental technologies such as computer technology, mathematical algorithms, and deep learning, society as a whole is now in an era of the Internet, digitalization, and intelligence. The era is characterized by the interconnection of everything, with rich and complete databases and algorithms at its core, that is, "people to people, machines to machines, and machines to people are linked into one." This means that all content involved in production and use scenarios is accompanied by "detailed, full-process data." As a result, digital technology and artificial intelligence technology are specifically applied in mobile payment, autonomous driving, intelligent navigation, and other fields, which greatly improves the efficiency of work and life.

[0003] In contrast, the construction industry, both domestically and internationally, lags far behind the digital age and is still in the stage of standardization and informatization.

[0004] Continuous improvement in industrial efficiency is an inevitable path. The following are examples of the reasons for the current situation in China: 1. No essential need for BIM: 1) Due to three reasons, namely, "the regulations use CAD drawings as legal documents, owners do not need BIM models, and CAD drawings can 'make do' with the needs of cost and construction," there is no demand in the market for "true BIM that can make cost and construction better and more efficient."

[0005] 2) The current CAD software meets the minimum requirements: Starting with the leading profession in architecture, each profession only cares about itself: (1) CAD meets non-digital needs: At the level of "medium to low efficiency", CAD is compatible with manual management; (2) Customers are unwilling to pay for BIM: The crude manual project management model cannot be integrated with the refined digital BIM.

[0006] 2. The implementation of BIM technology has a high technical threshold: 1) Technical requirements: BIM forward design requires designers to have high technical skills and be proficient in a variety of software and tools.

[0007] 2) Insufficient training: Many designers lack systematic BIM training and find it difficult to apply it effectively.

[0008] 3) Lack of multi-skilled personnel: The lack of multi-skilled technical personnel who are proficient in both design and BIM is a major problem faced by design companies.

[0009] 3. The initial investment in establishing BIM is large: 1) Lack of standards: The lack of unified standards and specifications for BIM leads to difficulties in collaboration between different companies and projects.

[0010] 2) Time cost: It takes time to adapt to switch from traditional design to BIM design, which may affect efficiency in the short term.

[0011] 4. A large amount of repetitive, low-quality BIM modeling in the industry: These low-quality BIMs have adverse effects.

[0012] Starting with leading construction professionals, they only care about themselves, resulting in a situation of "a large amount of repetitive, low-quality BIM modeling, leading to a lot of redundant construction and wasted costs in the industry." 1) For cost estimation majors, it is necessary to create a simplified model themselves; 2) Equipment also needs collision checks, and construction professionals also need construction guidance.

[0013] 5. Difficulties in project collaboration when using BIM: 1) Low input-output ratio: Most design companies are still in the stage of high input and low output. Due to the emphasis on speed and efficiency, it is difficult for companies to vigorously promote the application of BIM technology without the mandatory implementation by the owner.

[0014] 2) Profit distribution: BIM application may change the traditional profit distribution, and the lack of incremental benefits for all parties makes the participants less enthusiastic.

[0015] 3) High collaboration requirements: BIM requires close collaboration among design, construction, operation and maintenance parties, but in actual projects, there is insufficient collaboration among the parties.

[0016] 6. Insufficient application of BIM supporting software: 1) Software incompatibility: The biggest change in BIM implementation is the transformation of tools and technologies. The mainstream platforms are all foreign software products, and they have not yet been deeply integrated with domestic standards and specifications.

[0017] 2) Insufficient depth: Structural design is not well reflected in various BIM applications. For example, Revit, which has been widely used, does not have an independent structural professional module. The structural professional can only perform rough beam, slab and column modeling design, and cannot perform detailed node design or structural analysis.

[0018] 3) Regulations and standards have not been integrated with and implemented in BIM. The numerous and illogical standards, coupled with various market, product, and human factors mentioned above, make existing standards difficult to apply, hindering their smooth implementation and widespread adoption.

[0019] In summary, the core issues of "lack of demand, low cost-effectiveness, high barriers to entry, lack of universality, and industry-wide manual processes" have resulted in a situation where BIM is largely ignored in the industry, hindering its widespread adoption despite numerous long-term benefits. To increase the application rate of BIM-based forward design in China, addressing the aforementioned "overcoming technical and management challenges and generating demand" is the most crucial breakthrough. This should be combined with approaches from multiple angles, including "policy guidance, system construction, incentive mechanisms, standard setting, and talent cultivation," to create a healthy ecosystem that promotes the widespread adoption of BIM technology in China's construction industry.

[0020] Therefore, existing technologies still need further development. Summary of the Invention

[0021] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a method and system for deepening and finalizing the three-dimensional model of an engineering target. In layman's terms, it "provides a digital integrated system that makes CAD and BIM software no longer mindless tools, but automatically operates based on specifications and data conditions," in order to solve the problems existing in the prior art.

[0022] To achieve the above-mentioned technical objectives, according to a first aspect of the present invention, the present invention provides a method for deepening and finalizing a three-dimensional model of an engineering target, comprising: S1. Obtain the preset ontological attribute information and preset external association information of the components of the engineering target object from user input or pre-stored information in the system; S2. Based on the preset ontological attribute information and preset external association information of the constituent components of the engineering target, construct and / or update the three-dimensional model of the engineering target.

[0023] Specifically, the preset external association information includes at least one of the following: Technical basis documents: such as specifications, technical drawings, project documents, and professional calculation sheets; Production resources: such as material / equipment supplier list, product certificates, cost information parameters; Product performance parameters: expressed as specific name, corresponding grade, data such as equipment model, power, speed, head, design load, seismic grade, design parameters, and calculated values. Process documents: such as design documents, construction documents, cost estimates, and operation and maintenance documents; Collaborative management features: such as responsible persons, version history, and change logs.

[0024] Specifically, the preset ontology attribute information includes at least one of the following: Product 2D blocks, product 3D families; Geometric and physical characteristics: such as geometric dimensions, shape, volume, material density, and material type; Technical identifiers: such as unique component codes, industry codes for materials / equipment; Standardized related values: such as the length, width, height, area, volume, distance from the outside world, and installation dimensions.

[0025] Specifically, step S1 includes: S10. Establish a digital engineering design system, and complete or import / export design documents with a design depth that meets a preset standard in the system. The design documents with a design depth that meets the preset standard contain preset ontological attribute information and preset external association information of the constituent components of the engineering target.

[0026] Specifically, step S2 includes: S20. Convert the design file with the design depth reaching the preset standard into a three-dimensional model of the engineering target object. The three-dimensional model contains preset ontological attribute information and preset external association information of the constituent components of the engineering target object. The method for constructing the three-dimensional model of the engineering target object includes at least one of the following: Direct conversion: A one-time conversion from design files to 3D models, during which the corresponding preset ontological attribute information and preset external association information data remain unchanged; Automatic recognition and conversion: Through multi-level recognition, assignment, value retrieval and calculation, a three-dimensional model and its comprehensive data are generated, while keeping the existing data unchanged during the conversion process.

[0027] Specifically, the method further includes: When a user selects or boxes any component of an engineering target on the software display interface, the software outputs the preset intrinsic attribute information and preset external association information of that component. The output preset intrinsic attribute information and preset external association information of that component are editable and are used to display and / or update the preset intrinsic attribute information and preset external association information of that component.

[0028] Specifically, the construction method of the three-dimensional model includes: Users can edit the model family library, using the preset ontology attribute information and preset external association information corresponding to the target engineering object stored in the system as the basis for editing; wherein, the method is based on the system's built-in value database and algorithm.

[0029] Specifically, the digital engineering design system includes multiple databases and algorithms for managing the preset ontological attribute information and preset external association information of the constituent components of the engineering target. The databases and algorithms are used to establish links and edit the preset ontological attribute information and preset external association information in the design file or 3D model, so as to realize the unified storage and retrieval of the preset ontological attribute information and preset external association information.

[0030] Specifically, the method further includes: Using a unified graphics and family library, the conversion from design files to 3D models or the entire 3D model design process can be realized; wherein, the unified graphics and family library ensures the consistency of the correspondence between the graphics and the model, including the unified standard of the graphic blocks in the design files and the 3D family library.

[0031] Specifically, the digital engineering design system incorporates and integrates the relevant engineering technical standards of the country and the automatic conversion algorithm designed accordingly; wherein, the technical standards include national specifications, local standards, atlases and international standards, and the automatic conversion algorithm is used to realize the logical mapping and calculation of data between design documents and three-dimensional models.

[0032] Specifically, the method also includes setting project prerequisites, which can be explicit or implicit, to enable subsequent automatic judgment; wherein, the prerequisites include engineering object professional classification information, engineering environment category, engineering object function or component parameters, and model details are automatically determined based on the conditions.

[0033] Specifically, the digital engineering design system is integrated with various 3D software and is applicable to all 3D software. The system assigns preset ontological attribute information, preset external association information, and all data related to the project's preconditions to the components of the engineering target object, so as to realize the full data conversion and linking of the 3D model, covering the engineering design, engineering construction, and engineering operation and maintenance stages.

[0034] Specifically, the digital engineering design system also establishes a database for different 3D software to realize data conversion between 3D software; wherein, the database includes a conversion value table for data mapping and model output between different 3D products.

[0035] Specifically, the method further includes: Appropriate operation permissions are set for data modifications of 3D design results. The modifications are recorded in the project database to ensure the uniqueness and traceability of all data related to the components of the engineering target, including preset ontological attribute information, preset external association information, and project prerequisites.

[0036] Specifically, the method also includes a 3D design process tracing and visualization playback of the components of the engineering target with preset ontological attribute information, preset external association information, and all data related to the project's preconditions; wherein, the process tracing records data changes throughout the entire design phase, and the visualization playback is based on the system database to realize the playback and auditing of the design history.

[0037] According to a second aspect of the present invention, a system for refining and finalizing a three-dimensional model of an engineering target is provided, comprising: The acquisition module is used to acquire preset ontological attribute information and preset external association information of the components of the engineering target object, either input by the user or pre-stored in the system. The control module is used to construct and / or update the three-dimensional model of the engineering target object based on the preset ontological attribute information and preset external association information of the constituent components of the engineering target object.

[0038] Beneficial effects: The method and system for deepening and finalizing the 3D model of engineering targets provided by this invention, through an innovative integrated data-model architecture, brings fundamental changes to the engineering construction industry. Its core beneficial effects are reflected in the following dimensions: I. Eradicate the deep-seated problem of data fragmentation and achieve seamless data integration throughout the entire lifecycle. In traditional engineering modeling, data such as component attributes, technical specifications, and production resources are scattered across various stakeholders, leading to repetitive modeling across the design, construction, and operation and maintenance phases. This patent pioneers a dual-track data system of "preset ontological attribute information" and "preset external relational information," deeply binding inherent attributes such as geometric features and technical identifiers with dynamic information such as specification clauses, supplier lists, and process documents to the 3D model. This atomic-level data encapsulation mechanism ensures that any modification to a component throughout the entire lifecycle of an engineering target, from design to demolition, automatically triggers synchronous updates of related data, completely eliminating cross-stage information transmission distortion and eradicating the long-standing "data silo" problem in the industry.

[0039] II. Reconstructing the automated modeling process to overcome the dual bottlenecks of efficiency and accuracy. Based on the intelligent conversion engine of the digital engineering design system, two precise modeling paths are pioneered: direct conversion technology is used for standardized components (such as door and window equipment) to retain the original design intent; for complex structures (such as steel reinforcement calculation and modeling in structural engineering), a multi-layer recognition algorithm is used to achieve specification-driven parametric generation. This method significantly reduces the workload and difficulty of manual work, transforming the traditional experience-based, step-by-step modeling and design into rule-driven, precise output. In particular, through the built-in automatic conversion algorithm for national and international standards, it ensures that the model generation process naturally complies with mandatory requirements, eliminating design compliance risks from the source.

[0040] III. Building an open and collaborative ecosystem to promote industry standardization. The system establishes a scalable component database through unified graphics and family libraries, as well as standardized specifications, supporting lossless compatibility with mainstream 3D software. This "create once, reuse everywhere" mechanism not only solves the problem of the disconnect between foreign software and Chinese standards but also significantly lowers the barrier to entry for BIM technology. The combination of access control and visual traceability functions enables precise location of engineering changes to the responsible person and operation node, building a transparent and trustworthy collaborative environment. More importantly, the technical standard system formed by this solution provides a reusable basic framework for the digital delivery of engineering construction, accelerating the industry's transformation from discrete operations to platform-based large-scale, complex collaboration.

[0041] IV. Activating the Deep Value of Models and Empowering the Intelligent Upgrade of Decision Making 3D models have evolved from geometric representations into dynamic data containers, enabling self-interpretation and self-verification through real-time association with technical data, resource options, and process records. In the design phase, pre-loading technical specifications as preconditions allows for proactive risk mitigation; in the cost estimation phase, the generated construction code can be directly retrieved and integrated with its data to rapidly generate cost-related deliverables; in the construction phase, the construction code can be directly retrieved to obtain the design and cost results, i.e., their data integration, enabling intuitive visualization of construction operations and robot task execution; in the operation and maintenance phase, equipment parameters and historical maintenance records can be directly retrieved to support preventative maintenance decisions. This data-driven decision-making model shifts engineering management from reactive response to scientific prediction, creating continuous value-added opportunities for the industry.

Detailed Implementation

[0043] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0044] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0045] Please see Figures 1-14 This invention provides a method for refining and finalizing a three-dimensional model of an engineering target, comprising: S1. Obtain the preset ontological attribute information and preset external association information of the components of the engineering target object from user input or pre-stored information in the system; S2. Based on the preset ontological attribute information and preset external association information of the constituent components of the engineering target, construct and / or update the three-dimensional model of the engineering target.

[0046] First, it should be noted that this method is implemented by the user or the system automatically triggering the model building command. The engineering target refers to physical objects such as building projects, civil engineering projects, and industrial equipment and facilities, whose components include the smallest functional units such as beams, columns, pipes, and equipment.

[0047] The following explanation uses a "water supply pump" as an example (Note: Fire protection engineering requires water supply equipment, therefore fire protection related information is involved). The preset attribute information is extracted from the system's built-in database. For example, when the user selects the "water pump" component, the system automatically loads its inherent attribute data, including the XBC8.5 / 30GJ model fire pump, which is a deep well pump set for water supply; and the geometric dimensions (800mm long × 600mm wide × 500mm high), material type (stainless steel SUS304), physical density (7.93g / cm³), performance parameters (flow rate, head, matching power, rated speed), and other unchangeable parameters.

[0048] Preset external related information is dynamically obtained by linking to external data sources, such as the technical basis of clauses 2.1.1, 5.1.1, and 5.4.1 of the "Water Supply and Drainage Design Code" associated with the water pump, the 3C certification and production license of the three suppliers, product qualification certificates and their electronic files (production resources), and installation and construction records (process documents).

[0049] During the model building phase, the system binds the two types of data mentioned above to the corresponding components of the 3D model through the API interface. When the user updates parameters such as seismic resistance level, the system automatically recalculates the structural system and refreshes the model structure according to the code prompts, realizing real-time linkage between the model and the data.

[0050] Understandably, this invention completely solves the common pain points of "data and model separation in traditional 3D modeling, high cost and low efficiency of manual integration and linkage processing". For example, in large-scale factory projects, the traditional method requires manual verification and matching of more than 2,000 equipment parameter tables with the model correspondence. On average, each equipment parameter has more than 10, which takes more than 200 hours and the error rate is conservatively above 10%, which is time-consuming and labor-intensive. However, this method, based on a system and a strict database and algorithm, automatically binds data, reducing the error rate to nearly 0.1% (infinitely close to 0), improving efficiency by more than 10 times. This avoids production accidents that cause manufacturers annual losses of tens of millions of yuan due to "defective products, downtime, and maintenance".

[0051] Specifically, the preset external association information includes at least one of the following: Technical basis documents: such as specifications, technical drawings, project documents, and professional calculation sheets; Production resources: such as material / equipment supplier list, product certificates, cost information parameters; Product performance parameters: expressed as specific name, corresponding grade, data such as equipment model, power, speed, head, design load, seismic grade, design parameters, and calculated values. Process documents: such as design documents, construction documents, cost estimates, and operation and maintenance documents; Collaborative management features: such as responsible persons, version history, and change logs.

[0052] In this embodiment of the invention, the technical basis information is specifically manifested as follows: when the system generates a fire pipeline model, it automatically associates with various corresponding specifications, such as the mandatory clause of Article 12.3.20 of the "Technical Specification for Fire Water Supply and Fire Hydrant System" GB50974-2014 regarding the spacing of pipe supports and hangers, and converts the "maximum spacing of 4.5 meters" required by the specification into automatic spacing annotations in the model.

[0053] Taking the supplier list as an example, when a user clicks on the water pump model, the system displays detailed information on 20 nationally certified suppliers in a sorting manner similar to Taobao, including filterable parameters such as product price range (3,000-12,000 yuan), delivery cycle (15-30 days), and contact information.

[0054] The implementation of process documents is reflected in the following ways: During the construction phase, front-line workers can obtain relevant document support in various ways. For example, when workers scan the QR code of a component or directly click the installation menu of the corresponding icon, the system pushes the installation video tutorial and acceptance standard document for that component.

[0055] Understandably, this invention constructs a full lifecycle data chain. A project application demonstrates that maintenance personnel can accurately predict equipment replacement cycles by retrieving 10 years of maintenance records associated with water pumps, avoiding operational losses due to production downtime caused by sudden failures and reducing annual maintenance costs by 3 million yuan.

[0056] Specifically, the preset ontology attribute information includes at least one of the following: Product 2D blocks, product 3D families; Geometric and physical characteristics: such as geometric dimensions, shape, volume, material density, and material type; Technical identifiers: such as unique component codes, industry codes for materials / equipment; Standardized related values: such as the length, width, height, area, volume, distance from the outside world, and installation dimensions.

[0057] In a preferred embodiment of the invention, the geometric features are implemented by defining multi-dimensional parameters. For example, for a reinforced concrete beam KL2, the system records its cross-sectional dimensions (300mm × 650mm), volume (0.585m³ / m), and spatial coordinates (the intersection of axis A-1 and axis 1-3). Technical identification is achieved through a unique coding system. For example, the code "PW-2023-SH-001" for a DN150 water supply pipe includes triple verification: project code, professional classification, and serial number.

[0058] The standardized correlation values ​​are dynamically calculated through an algorithm: when the user sets "hospital operating room" as the spatial attribute, the system extracts the relevant standard "Technical Specification for Clean Operating Room Buildings in Hospitals" GB50333-2013 based on the "hospital building" category and automatically calculates the wall thickness (≥120mm) and equipment installation spacing (≥600mm).

[0059] It is understandable that this invention achieves millimeter-level precision control. For example, in the installation of pipelines in nuclear power plants, by strictly adhering to the specifications and correlation values, the cumulative installation error of 2000 meters of pipeline can be controlled within ±2mm, far exceeding the industry standard of ±10mm.

[0060] Furthermore, the present invention provides specific implementation details of preset ontology attribute information and preset external association information, as shown in Table 1: Table 1. Specific Implementation Details of Preset Ontology Attribute Information and Preset External Association Information Specifically, step S1 includes: S10. Establish a digital engineering design system, and complete or import / export design documents with a design depth that meets a preset standard in the system. The design documents with a design depth that meets the preset standard contain preset ontological attribute information and preset external association information of the constituent components of the engineering target.

[0061] In a preferred embodiment of the present invention, the system setup process is implemented using a three-layer architecture: Basic layer: Deploy a distributed database cluster to store 20 million standard drawings (such as the 22G101-1 structural drawing set) and 500,000 material and equipment parameters; Service layer: Develop RESTful API interfaces to support mainstream software such as Revit and SolidWorks in obtaining data through plugins; Application Layer: A visual operation interface is constructed. For example, when a designer drags the "Concrete C30" material icon to the model area, the system automatically associates it with the 28-day compressive strength (30MPa) and elastic modulus (3.0×10⁻⁶). 4 13 parameters including MPa.

[0062] It is understandable that the present invention (1) forms a truly digital three-dimensional model result that integrates all data such as business rules and specifications, commercial data and three-dimensional components. (2) Such a truly digital three-dimensional software result can be converted between various three-dimensional software. Such conversion has high value and extremely high conversion efficiency. Actual tests show that it can realize the conversion between software and the cross-platform data call response time is about 10-20 minutes.

[0063] Specifically, step S2 includes: S20. Convert the design file with the design depth reaching the preset standard into a three-dimensional model of the engineering target object. The three-dimensional model contains preset ontological attribute information and preset external association information of the constituent components of the engineering target object. The method for constructing the three-dimensional model of the engineering target object includes at least one of the following: Direct conversion: A one-time conversion from design files to 3D models, during which the corresponding preset ontological attribute information and preset external association information data remain unchanged; Automatic recognition and conversion: Through multi-level recognition, assignment, value retrieval and calculation, a three-dimensional model and its comprehensive data are generated, while keeping the existing data unchanged during the conversion process.

[0064] In a preferred embodiment of the present invention (1) Direct conversion is applicable to standardized components whose geometric details do not need to be converted and deepened: For example, when importing CAD drawings containing door and window markings, the system converts 200 doors and windows into parameterized BIM models within 10 seconds through the preset "Door and Window Blocks-BIM Family Library" mapping table, and retains 120 attributes such as hardware models (such as HOPPE handles) in the original design.

[0065] (2) Automatic recognition and conversion is applicable to non-standard components whose geometric details need to be converted and deepened according to the specifications, i.e., to handle complex scenarios: such as when performing intelligent analysis on structural reinforcement drawings, the system first identifies the "Φ8@200" annotation symbol according to relevant specification clauses, and then calculates the reinforcement anchorage length (LabE=1500mm) based on the concrete strength (C30) and the protective layer thickness (25mm), and finally generates a three-dimensional reinforcement model containing details such as bending radius (3d).

[0066] Understandably, this invention achieves a significant leap in efficiency for modeling complex components. In a bridge project, the traditional method required three weeks to model 2,000 irregularly shaped steel bars, but this method, through automatic identification and conversion, completed the modeling within three hours, reducing the construction period by more than 95% and bringing the error rate close to zero.

[0067] Specifically, the method further includes: When a user selects or boxes any component of an engineering target on the software display interface, the software outputs the preset intrinsic attribute information and preset external association information of that component. The output preset intrinsic attribute information and preset external association information of that component are editable and are used to display and / or update the preset intrinsic attribute information and preset external association information of that component.

[0068] In a preferred embodiment of the present invention, the implementation adopts a three-step process of "selection-pop-up window-editing": when the user clicks on the air conditioning unit in the BIM model, the system pops up a data panel with layered display (in some cases): First layer: Body attributes (cooling capacity 1200kW, power 380V / 3P); Second layer: Related information (scanned copy of supplier A's maintenance contract); Third layer: Modification log (June 5, 2023, Engineer Wang adjusted power parameters).

[0069] After a user with the necessary permissions modifies any parameter, the system automatically sends a change notification to relevant parties (such as cost engineers and construction workers), triggers updates to related components (such as recalculating the capacity of the distribution cabinet), completes a small work loop, and the database update is finished.

[0070] Understandably, this invention reduces the change response time from the industry average of 72 hours to 10 minutes.

[0071] Specifically, the construction method of the three-dimensional model includes: Users can edit the model family library, using the preset ontology attribute information and preset external association information corresponding to the target engineering object stored in the system as the basis for editing; wherein, the method is based on the system's built-in value database and algorithm.

[0072] In a preferred embodiment of the present invention, for irregularly shaped components (such as curved curtain wall keel), the system provides a dedicated editor: after the user draws a three-dimensional curve, the system automatically generates a parametric model skeleton, and then associates three types of information (belonging to "preset ontological attribute information and preset external association information") through the "data binding wizard": Material properties (6061-T6 aluminum alloy yield strength 275MPa); Process requirements (Welding joint class A); Testing standard (GB / T5237.4-2017).

[0073] Special component data is stored in a project-specific library, supporting cross-project access.

[0074] Understandably, this invention reduces the design cycle of customized components by 70%.

[0075] Specifically, the digital engineering design system includes multiple databases and algorithms for managing the preset ontological attribute information and preset external association information of the constituent components of the engineering target. The databases and algorithms are used to establish links and edit the preset ontological attribute information and preset external association information in the design file or 3D model, so as to realize the unified storage and retrieval of the preset ontological attribute information and preset external association information.

[0076] In a preferred embodiment of the present invention, the core database adopts a three-tier architecture: Main database: Stores national standards (such as GB50016 fire protection code), and is automatically updated in sync with the publisher; Project database: Real-time recording of component modification history (1000 concurrent writes per second); Cached database: High-frequency data preloading (such as commonly used rebar model parameters). Algorithm engine implements dynamic scheduling: When performing pipe collision detection, the spatial topology algorithm is called first, completing the collision analysis of 100,000 components within 5 minutes, which is 20 times faster than traditional software.

[0077] Specifically, the method further includes: Using a unified graphics and family library, the conversion from design files to 3D models or the entire 3D model design process can be realized; wherein, the unified graphics and family library ensures the consistency of the correspondence between the graphics and the model, including the unified standard of the graphic blocks in the design files and the 3D family library.

[0078] In a preferred embodiment of the present invention, the present invention establishes a cross-platform family library standard system: Geometric standards: All components are modeled using NURBS surfaces, with tolerances controlled within 0.1mm (e.g., curtain walls). Data interface: Defines a general attribute template in XML format (containing 48 required fields); Version control: The family library files are digitally signed (SHA-256 encrypted) to prevent unauthorized modification.

[0079] Implementation Case: In a certain project, multiple participating units shared a unified family library to eliminate model docking errors.

[0080] Understandably, this invention achieves a model reuse rate of up to 95%, significantly reducing engineering modeling costs.

[0081] Specifically, the digital engineering design system incorporates and integrates the relevant engineering technical standards of the country and the automatic conversion algorithm designed accordingly; wherein, the technical standards include national specifications, local standards, atlases and international standards, and the automatic conversion algorithm is used to realize the logical mapping and calculation of data between design documents and 3D models, and output.

[0082] In a preferred embodiment of the present invention, the specification clauses are converted into executable logic: for example, when a user sets "seismic fortification intensity 8 degrees" in the structural engineering work path, the system automatically executes a third-order operation: Search for relevant clauses in the "Code for Seismic Design of Buildings" GB50011 Calculate the spacing of the stirrup reinforcement zone at the beam-column joint (min(6d,100mm)). The reinforcement layout of 3000 node areas in the model was corrected.

[0083] In terms of international standard compatibility, the system has a built-in ISO19650 converter that automatically matches the parameters of American standard ASTM A36 steel to Chinese standard Q235.

[0084] Understandably, this invention has increased the design compliance rate from 85% to 99.9% through manual review and shortened the time for projects to pass regulatory review by 60%.

[0085] It should be further explained that the digital engineering design system supports the entire process through the following technologies, as shown in Table 2: Table 2 Implementation methods of digital engineering design system Specifically, the method also includes setting project prerequisites, which can be explicit or implicit, to enable subsequent automatic judgment; wherein, the prerequisites include engineering object professional classification information, engineering environment category, engineering object function or component parameters, and model details are automatically determined based on the conditions.

[0086] In a preferred embodiment of the present invention, a latent condition recognition technology is designed: the system uses an NLP engine to parse the design specification text, automatically extracts key information such as "Biosafety Level 3 Laboratory," and then triggers: Pressure gradient control (-15Pa to -40Pa); Airtight door class (Class III); Selection of high-efficiency filters (H14 grade).

[0087] The explicit condition setting adopts a wizard mode: after the user selects the "coastal corrosion environment" option, the system forces all steel structure coatings to have a thickness of ≥200μm.

[0088] Understandably, the automatic anti-corrosion design can significantly extend the equipment's lifespan by 8 years, greatly reducing the total lifespan maintenance cost.

[0089] Specifically, the digital engineering design system is integrated with various 3D software and is applicable to all 3D software. The system assigns preset ontological attribute information, preset external association information, and all data related to the project's preconditions to the components of the engineering target object, so as to realize the full data conversion and linking of the 3D model, covering the engineering design, engineering construction, and engineering operation and maintenance stages.

[0090] Specifically, the digital engineering design system also establishes a database for different 3D software to realize data conversion between 3D software; wherein, the database includes a conversion value table for data mapping and model output between different 3D products.

[0091] In a preferred embodiment of the present invention, the three-dimensional software integration scheme includes (but is not limited to): 1. Develop a Revit plugin to add a "Chinese Standards" tab to the Properties panel; 2. The SolidWorks environment embeds a material library selector via an OLE interface; 3. The web-based version uses WebGL technology to enable lightweight model viewing.

[0092] Data conversion employs a dual mechanism: universal format conversion (IFC file) supports basic geometry transfer; deep conversion uses a "semantic mapping table" to precisely map Revit's Family parameters to ArchiCAD's GDL objects.

[0093] Understandably, this invention achieves a 40% improvement in cross-platform collaboration efficiency and significantly reduces the time spent on model conversion in projects.

[0094] Specifically, the method further includes: Appropriate operation permissions are set for data modifications of 3D design results. The modifications are recorded in the project database to ensure the uniqueness and traceability of all data related to the components of the engineering target, including preset ontological attribute information, preset external association information, and project prerequisites.

[0095] In a preferred embodiment of the present invention, a hierarchical access control system is also designed, and examples of its application are as follows: Designer: The core properties can be modified, but the associated values ​​of the specification are frozen; Auditor: Must have the authority to cover the standard clauses and must undergo two-factor authentication; Owner: Only view the final model, and keep a record of all actions on the blockchain.

[0096] Data traceability uses version tree technology: each modification generates a model snapshot with a timestamp, supporting retrieval by three dimensions: responsible person, time range, and component type.

[0097] Understandably, in a project dispute, clarifying the responsible party within 10 minutes by retrieving historical versions can largely avoid legal losses.

[0098] Specifically, the method also includes a 3D design process tracing and visualization playback of the components of the engineering target with preset ontological attribute information, preset external association information, and all data related to the project's preconditions; wherein, the process tracing records data changes throughout the entire design phase, and the visualization playback is based on the system database to realize the playback and auditing of the design history.

[0099] In a preferred embodiment of the invention, the invention implements phased recording: Design phase: Record the 7 optimization processes of the beam cross-section from 300×600 to 350×650; Construction phase: Verify the consistency between the rebar binding and the model by referring to on-site photos; Operation and maintenance phase: Provides instructions on model disassembly animations when replacing playback devices.

[0100] The playback engine supports speed adjustment from 0.1x to 5x, and text annotations can be added to key operation nodes.

[0101] Understandably, the efficiency of new employee training has increased by 300%, and the on-the-job training cycle can be reduced from 3 months to 3 weeks.

[0102] The workflow of this invention is illustrated below through specific examples: The method provided by this invention is applicable to the detailed design and digital conversion of BIM software for all types of projects. The specific working principle of this patent is explained below using a case study of a building engineering project as an example: 1. Example background and explanation of the method: As shown in Table 3 below, these two cases represent two scenarios for typical components and equipment in engineering projects.

[0103] Table 3 shows examples and corresponding flowchart paths. 2. Establishment of basic conditions: The system first needs to be established in two main aspects: software system and industry-level "database + algorithm", as shown below: 2.1 Software Components: As shown in Table 4, the software consists of three components: "system, CAD, and BIM". Currently, there are many BIM versions. After a user selects a BIM version (the most common one is the American REVITE), this BIM software either uses a BIM plugin to communicate and integrate with the system, or it is a self-developed BIM software integrated into the system for data communication and integration. Table 4 Software System Composition 2.2 Databases and Algorithms: The conditions for realizing this patent are "multiple key databases and multiple algorithms", and the combination of the two constitutes a specialized functional engine; 2.2.1 Database 2.2.1.1 System Database 2.2.1.1.1 System Architecture As shown in Table 5, the system database is the overall architecture that integrates all rules governing the engineering industry (such as technical specifications, BIM standards, product manufacturing templates, etc.). Together with the algorithms, it serves as the logic for executing business processes within the engineering industry, i.e., a "standardized workflow." In addition to common basic software functions, specialized business scenarios are illustrated in the following examples; Table 5 System Configuration Diagram 2.2.1.1.2 Convert the database: As shown in Table 6, Figures 1-3 As shown, the transformation database is a general database that integrates "components, equipment and their corresponding data (attributes, related information, etc.)" (as shown in the example below, which consists of multiple tables). Together with the algorithm, it is the basis for the logic of business execution in the engineering industry, namely the "standardized workflow" (Table 5). The characteristics are explained in the two-dimensional CAD and three-dimensional BIM forms in Table 6 below. (1) The "graphics and models" used in the same "components and equipment" of the project are unified, that is, CAD and BIM in the system (such as the two-dimensional CAD and three-dimensional BIM forms of water pumps in the table below). (2) The uniqueness of content attribute data belonging to the "components and equipment" of the project throughout the entire process means: 1) "The data remains unchanged throughout the entire process from CAD to BIM; only the surface symbols change" (such as product model, manufacturer, etc.). 2) Data added in subsequent processes such as "construction quality inspection, cost settlement, operation and maintenance" will be added to the attribute library of the structure, node, or component, ensuring validity and uniqueness; Table 6 shows the system's built-in method for assigning values ​​to components when converting CAD to BIM (partial example). 2.2.1.2 Project Database: A project database is a collection of all the actual operational results data from the entire lifecycle of a specific engineering project, including "preliminary stage, design, construction, and operation and maintenance." Its characteristics are: The project database is a "bookshelf" that is formed according to technical and management standard formats (and is constantly updated throughout the process) and is the latest version (all projects follow the same pattern, i.e., standardization). 1. Dynamic accumulation and updating of project data: Whenever new project data is updated, it is recorded in the corresponding location of the project database, including versions of various process changes; 2. Attributes and related information data are the core data generated during the CAD and BIM detailing process: 1) The uniqueness of the whole process "one number to the end" means that "the data remains unchanged throughout the process of CAD to BIM 'writing existing data', and only the surface symbols change" (such as product model, manufacturer, etc.), such as the design parameters and performance indicators of water pumps; 2) Attribute data is accumulated by continuously adding and updating the data results of each stage throughout the project life cycle, such as water pumps: (1) Add and update design results when entering the design stage; (2) Add and update data including construction, quality inspection and settlement results when entering the construction stage; (3) In the operation and maintenance stage, you can see the previous "design and construction" results data, add and update operation and maintenance management data, etc. 2.2.2 Algorithm: An algorithm is the "logic of data operation," encompassing multiple dimensions of "conditions, processing, and delivery" within and between "regular software" and "business-specific" data. It is essentially a standard "workflow and method," applicable to various data processing within systems and various databases. Some algorithm functions are shown in Table 7 below. Table 7 System Algorithm Composition 3. Case Study Process Explanation: The project BIM design deliverables that can be used for collaborative production across the entire industry process, and that provide a complete overview of all design models and text, as well as the associated "design, construction" and other related data, are what all parties involved in the entire industry process need. There are two methods: "converting from CAD" and "generating entirely using BIM design," which are explained below: 3.1 Method 1: Import from CAD: The workflow for this task is as follows: During the design phase, the CAD design files (including drawings and design specifications) containing "attached attributes and related information" data in the system are converted into "BIM models and text containing "attached attributes and related information" data.

[0104] 3.1.1 Open the BIM software and prepare for conversion: The data of the designed model and text can be queried by two methods: (1) by installing a specially developed plug-in to communicate with the local BIM, and (2) by combining the system’s own developed BIM software. The data is stored in the corresponding project database in the system’s backend and is available for BIM to call (such as the data of a water pump used in a project design stored in the backend database). 3.1.2 Importing CAD Results: The system already possesses the capability to import CAD results and generate "block-like, non-detailed design-depth BIM models"—models lacking detailed data. However, this lack of detailed data renders BIM worthless in business operations. True high value comes from endowing BIM with fully digital data to improve efficiency, reduce costs, and enhance business processes. The steps are as follows: 3.1.2.1 CAD Deliverables: The CAD deliverables here are CAD drawings (plans, elevations, sections, and construction drawings) and CAD version design specifications that are "system-based, contain complete design data, and cover all disciplines". 3.1.2.2 Introduction to CAD Result Data: Currently, CAD drawings and design specifications completed by standalone CAD software are essentially "data-free and bare," generally lacking detailed data and unable to promote improvement or enhance production efficiency. A truly qualified digital project deliverable consists of three types of finished products: "professional classification information deliverables, CAD drawings and design specifications or BIM models and design specifications with complete material and equipment option data," and the main workload of the CAD "construction drawings and design specifications" is automatically generated by the system.

[0105] In the CAD drawings and design specifications with complete data, all design data is stored in various databases in the system backend according to the "legend-data" format shown in Table 6. The three elements of "drawings, design specifications, and data" constitute a complete and deliverable CAD result (e.g., if the CAD design of a project has been completed, the data such as "equipment model, design parameters, and optional suppliers" of one water pump in the fire pump room have been "linked with the text and graphics in the drawings and design specifications, and this data is stored in the system"). Table 8 provides examples of the "Legend - Data" content composition in the "Drawings and Design Specifications" section of the project's CAD deliverables. There are many specific methods for displaying CAD data, such as... Figure 4 One type is shown; 3.1.3 Detailed design of the BIM model: like Figure 5 As shown, a BIM model with "block-like structure and no detailed data" that lacks detailed design depth can be converted into a "BIM model with detailed design depth" through three methods. This step is the core stage; its essence is to "allow the transformed model to carry the existing data and continue counting to the end." There are three specific methods as follows: 3.1.3.1 (Method 1-1) Automatic conversion directly in the background It is mainly applicable to the conversion of CAD design finished products that "have complete explicit features (such as shape and physical description)". The CAD finished products referred to here are CAD drawings (plan, elevation, section, construction drawings) and CAD version design specifications that are "based on the system, with complete design data (such as Table 8) and each of the disciplines".

[0106] The steps for Method 1-1 are as follows; (For example, for the water pump mentioned above, before it is converted to BIM, its design data such as "equipment model, design parameters, and optional suppliers" is "complete", thus allowing it to be successfully used for industry communication and production). In BIM software that integrates with the system data chain, select "Professional Type, Start This Task" and the software will begin execution.

[0107] All of the following 5 steps run in the system background after the user starts the system; 1. Verification and value retrieval: Processing the same project deliverables is based on the "system, CAD, BIM" software environment and a unified "materials, equipment, structure, and nodes" library, completing two tasks: "identification (of the same project) and value retrieval (of stored stage data)".

[0108] Based on two documents (1) a value table corresponding to two-dimensional and three-dimensional CAD components (all “materials, equipment, structures, nodes”) and three-dimensional BIM families (all “materials, equipment, structures, nodes”), and (2) a product information table for the mall, taking “water pump” as an example, in the system, the system recognizes the two-dimensional example of “water pump” as follows: (see Table 5, Table 6, Table 8 for the value table) Figure 1 , Figure 3 ).

[0109] 2 Generation: Based on the results of "identification and value retrieval," the system uses data links to ensure that the families of the BIM model (all "materials, equipment, structures, and nodes") have the same data attributes as the CAD components (all "materials, equipment, structures, and nodes"). This means that the "table" (form) is replaced by the "BIM model," while the "data" remains "data that continues unchanged from the CAD drawing." There are many specific methods for displaying this, such as... Figure 7 As shown; 3. Generate BIM versions of the "Design Specification" and various thematic descriptions: Within the system, through functions such as data linking and task templates, each professional work module generates corresponding BIM version "Design Specifications" deliverables and thematic descriptions based on the generated BIM model. 4. Professional Collaboration: Within the system, through functions such as data linking and task templates, each discipline can revise and improve the BIM results at two points: "BIM version of the 'Design Specification' for each discipline is generated" and "BIM software product conversion results are generated". These results are then uniformly confirmed as "BIM model of detailed design". 5 (Possible) conversions between BIM software: The system has a "data and algorithm" conversion function for BIM software products from different companies. Through data linking and other functions, it realizes the conversion between different BIM software products, and the result is a "detailed design BIM model". 6. Deliver a BIM with complete data: The system verification is complete.

[0110] By opening BIM software, you can see the model and related data for the entire project lifecycle; 3.1.3.2 (Method 1-2) Automatic conversion calculation in the background This function is "based on technical specifications, performs multiple algorithm transformations, and includes all attributes and related information data". Its purpose is to complete specific tasks that any project needs to accomplish through the "calculation and transformation" function.

[0111] Currently, BIM software is merely general-purpose software. Due to the lack of "industry technical logic (such as national standards)" (in layman's terms, current BIM software is similar to "a single hardware tool without brains or ideas | "wrench", arbitrary and inefficient"), it cannot achieve functions such as automatic conversion of structural reinforcement. There are cost modeling software such as Guangliandaswell on the market that are "simplified versions, only with structural reinforcement modeling functions" to supplement and realize this function. The core of this method is the second key method to enable BIM to carry all data (in layman's terms, digital BIM is similar to an "industry-level hardware tool kit with brains and intelligence, a smart wrench kit, professional and dedicated"). It is mainly applicable to "completing specific tasks through the 'calculation and conversion' function", such as "refinement and conversion of steel reinforcement structure" in structural engineering. The CAD finished products referred to here are CAD drawings (plan, elevation, section, construction drawings) and CAD version design instructions "based on the system, with complete design data (such as Table 8) and each of the specialties".

[0112] The case scenario is: the creation process of the longitudinal reinforcement bar at the bottom of a frame beam called KL2 in the bathroom "from CAD to BIM" (similarly, the models and data of all structural beams, slabs and columns are the sum of all the KLX reinforcement bars completed in sequence). The frame beam is composed of dozens of different steel bars. Each one is converted into a detailed design BM model with data, thus completing the BIM modeling of the frame beam and including all the data. In BIM software integrated with the system chain, select "Professional Type, Start This Task" and the software will begin execution.

[0113] All of the following 5 steps run in the system background; (1) Automatic conversion section: 1. Identify the reinforcement diagram of the structural beam: Based on the "Structural Code and Drawing Set 22G101-1" database, the system adopts one or more of the following methods: "third-party BIM software integrated with the system through a plug-in" or "self-developed BIM software integrated with the system". The system identifies the "related lines and text" (axis lines, beam lines, steel bar symbols, specific reinforcement data, etc.) of the imported structural beam reinforcement drawings and categorizes them into the project database. 2. Analysis of beam configuration information: According to the beam code in the project database, the beam type configuration information is given. For example, the code KL2 (2A) 300x650 indicates a floor frame beam numbered KL2 with a span of 2 spans, a cantilever at one end, and a cross-sectional size of 300x650 (for details, please refer to pages 1-22 and 1-23 of the "22G101-1" drawing set). 3. Specify the minimum thickness of the beam protective layer: The prerequisite is that the architectural profession has defined the function of the building space where the steel bar is located as "bathroom" in the "Project Professional Classification Information and Drawings". Therefore, the environmental category of the structural components in the relevant area of ​​the bathroom can be further determined as "IIa" and the minimum thickness of the protective layer of the beam is 25mm (according to page 2-1 of "22G101-1" drawing set and Articles 3.5.2 and 8.2.1 of "Code for Design of Concrete Structures"). 4. Analysis of the reinforced concrete grade, steel reinforcement type, and seismic resistance grade of the beam: The system further automatically analyzes the data in the project database to determine the "strength grade of reinforced concrete, strength grade of reinforcing steel, type of reinforcing steel, and seismic grade" of the beam. Ultimately, it can automatically determine the basic anchorage lengths of tensile reinforcement (Lab, LabE, La, LaE, etc.) for seismic design based on the "22G101-1" standard drawing. 5. Spatial positioning and anchorage length in the column (support): Based on the parameter definitions above, the "spatial positioning and anchorage length in the column (support)" of the steel bar in the specific beam section can be determined, i.e., BIM model generation; two examples of its functional scenarios are provided ( Figure 9 ): 1) Matching one by one: Click on ① structural beam to see the KL2 steel reinforcement model and detailed information in the corresponding construction (the yellow part in the figure is its model, and the detailed information is in the BIM interface). 2) Real-time statistics: The system and BIM provide data summaries for all topics, including "materials / equipment, design documents, construction documents and operation and maintenance phases", as needed, covering all stages of the entire lifecycle; Table 9. Examples of Data Content Composition for Longitudinal Reinforcement at the Bottom of KL2 Frame Beams 6. Integration of Reinforcing Steel Related Data: and Figure 4 Similarly, the system provides data integration for all nodes of the project's entire lifecycle, including "preliminary stage, design, construction, and operation and maintenance." For example, data such as "design parameters and optional suppliers" for steel reinforcement in the design stage can be viewed. Note: This sixth step is a unique feature of the digital system and is the most valuable function for industry users (including all professions in construction engineering). 7. Follow-up work 7.1 Generate BIM versions of the "Design Specification" and various thematic descriptions: Within the system, through functions such as data linking and task templates, each professional work module generates corresponding BIM version "Design Specifications" deliverables and thematic descriptions based on the generated BIM model; 7.2 Professional Collaboration: Within the system, through data linking and other functions, each discipline can revise and improve the results generated by the system and BIM at two points in time: "BIM version of the design specification for each discipline is generated" and "conversion results of different BIM software products are generated". The system will then uniformly confirm and deliver the "detailed design BIM model". 7.3 (Possible) Conversion between BIM software: The system has a "data and algorithm" conversion function for BIM software products from different companies. Through data linking and other functions, it realizes the conversion between different BIM software products, and the result is a "detailed design BIM model". 7.4 Deliver a BIM with complete data: Within the system, by opening the BIM software, one can view the model and related data for the entire project lifecycle, and complete the entire process of "viewing and outputting" according to user needs; 7.4.1 Review: Within the system, by opening the BIM software, you can view the model and related data for the entire project lifecycle; 7.4.2 Output: Based on user needs and permissions, the system aggregates existing data and then provides corresponding output data (forms) according to "system-provided or user-defined databases derived from standards and experience" for actual business applications. The following are two examples: "water pump" and "reinforcing steel". 1. Water supply pump: Users need to know the list of various models of "drainage pumps" for this project.

[0114] The system automatically provides all or part of the following data: "Project Name, Water Pump Model, Quantity, Location, Corresponding Sub-project, Project Data"; 2. Reinforcing steel: Users need to know two lists: "Reinforcing steel quantity" and "Detailed specifications".

[0115] The system automatically provides: (1) a bill of quantities for steel reinforcement (such as Table 9, additional item names, and other basic information); (2) steel reinforcement detailing results, which include: component name (such as KL2), steel reinforcement number (such as ①, ②), steel reinforcement specifications (diameter such as Φ8, Φ12, Φ25), steel reinforcement grade (such as HRB400, HRB500), single cutting length (cutting length accurate to millimeters), bending shape diagram (detail drawing, data from the drawing set screenshot), number of single pieces, total number of pieces, and total weight; The above are directly used for "cost calculation related to steel bars, steel bar procurement and processing production".

[0116] 3.1.3.3 Methods 1-3: Manual Operation The steps are to repeat the steps above, omitted.

[0117] This method is a supplementary approach, designed for "individual, small-scale, and unexpected" situations (after all, projects are subject to countless variations, and this accounts for less than 5%). The core of this method is to establish a link between the system and related BIM software for the uniquely added design content of the project, such as "structure, nodes, and equipment," including all data, i.e., "outcomes-data." (For example, if a project adds a decorative column for ethnic minorities, this is a rare case and accounts for a very small percentage; the user can simply assign the data for that decorative column.) 3.2 Method 2: Full BIM Design The workflow of this model is as follows: During the design phase, the entire design process utilizes a "system + BIM software" approach, involving gradual refinement without conversion. Specifically, within the system, the design is completed through three progressive steps: "rough (conceptual scheme depth), complete (formal scheme depth), and detailed (construction drawing depth)," resulting in a "complete BIM model with relevant attributes and data" along with supporting documents (BIM-based design specifications and thematic descriptions). The steps are as follows: 3.2.1 Project Professional Classification Information: As shown in Table 10 and Figure 10As shown, the data of the designed model and text can be queried by one of the two methods: "(1) communicating with the local BIM by installing a specially developed plug-in, and (2) combining the BIM software developed by the system itself". The data is stored in the corresponding project database in the background of the system and can be called by BIM at various stages (such as the data of the water pump used in the project design stored in the background database). Table 10 Examples of the essential components of the data included in the project deliverables during the design phase 3.2.2 Open BIM software to do the design: This is the current standard procedure, which includes three progressive steps: "rough (conceptual design depth), complete (formal design depth), and detailed (construction drawing depth)".

[0118] This refers to either a standalone version of BIM that communicates with the system via "plugins," or a self-developed BIM software integrated with the system.

[0119] 3.2.3 BIM model of the conceptual scheme: The depth level of conceptual design BIM is "meeting the depth requirements of conceptual design without detailed data". In business terms, it is "providing a principled design". Taking building construction as an example, a conceptual design is "a design communicated with the owner by the architect in the early stages of project design" and meets and expresses principle indicators such as "main functions, building area, building height, design style, and controllable cost".

[0120] This stage does not require providing "attributes and related information" data. A few special, personalized attributes need to be set by the user (such as special glass or stainless steel plates for visual effects). Figure 11 As shown.

[0121] 3.2.4 BIM model of the design scheme: The formal BIM scheme is still "a model without details (similar to a child's toy car)", only the professional content is complete (the depth of the formal scheme). In business terms, it is to "provide a scheme that expresses the complete content", that is, to provide a scheme that "shows what the client can see and obtain". Taking building construction as an example, the formal scheme is "the scheme communicated by the architect and the owner in the middle of the project design", which meets and expresses "clearer functions, building area, building height, contents, finished cost" and other feasible indicators.

[0122] This stage requires the addition of complete attributes and related information data, including (1) on the user side, providing "key attributes and related information" data (to meet visual requirements); (2) on the system side, providing "material and equipment optional reference pools" for similar projects, such as general materials and equipment like wall materials, glass, and fireproofing (each with 3 to 5 options), and more, including "investment estimates" from the cost engineering profession. After comprehensive collaboration and confirmation by engineering design-related professions, the two images in the case study are as follows. Figure 11 and Figure 12 As shown, Figure 11 It is evident that the main principles (the shape of the building, spatial relationships, etc.) are not detailed in terms of technical construction. Figure 12 It is evident that the main deliverables (doors, windows, stairs, cabinets, etc.) lack technical construction details.

[0123] 3.2.4 Detailed Design BIM Model: Within the system, based on the functions of "CAD, BIM, data, and algorithms," BIM detailed design reaches "construction drawing depth" and can be used for "cost estimation (budgeting and settlement), bidding, construction, and operation and maintenance." According to the current technical path classification of engineering professions and businesses, detailed design involves creating BIM models of various professional structures. There are three common methods for detailed design, such as... Figure 13 and Figure 14 As shown: 3.2.4.1 Method 2-1 (Automatic conversion in the background) Direct conversion The core functions of this step are two: "verifying completeness" and "generating subsequent design deliverables". If a project's BIM design has been completed, and there is a water supply pump in the fire pump room, the system (1) checks its attributes and whether there are any related details, and (2) generates the subsequent BIM version of the "Design Description, Special Description" and construction documents, etc. 1. Verification and Improvement: Based on the design content, BIM automatically generates design items (such as water pumps). First, the system checks the attributes and related information in the BIM solution deliverables to see if they exist and where they come from (provided by the system). If there are any deficiencies, the system provides a list and prompts the user to supplement them. Second, the user supplements and improves the information until the system has verified that everything is complete.

[0124] When an incomplete submission occurs, the system will prevent the submission from succeeding and will not allow you to proceed to the next step. 2. Generate BIM versions of the "Design Specification" and various thematic descriptions: Within the system, through functions such as data linking, each professional work module generates corresponding BIM version of the "Design Specification" deliverables and thematic descriptions based on the generated BIM model; 3. Professional Collaboration: Within the system, through functions such as data linking, each discipline can revise and improve the results generated by the system and BIM at two points: "BIM version of the 'Design Specification' for each discipline is generated" and "Conversion results of different BIM software products are generated". The system will then uniformly confirm and deliver the "Detailed Design BIM Model". 4. Possible conversion between BIM software: The system has a "data and algorithm" conversion function for BIM software products from different companies. Through data linking and other functions, it realizes the conversion between different BIM software products, and the result is a "detailed design BIM model". 5. Deliver a BIM file with complete data: The system verification is complete.

[0125] By opening BIM software, you can see the model and related data for the entire project lifecycle; 3.2.4.2 Method 2-2 (Automatic calculation and conversion in the background) The story is the same as above: the birth of a longitudinal steel bar at the bottom of a frame beam in the bathroom named KL2 "throughout the BIM process"; Currently, BIM software itself is only general-purpose software. Due to the lack of "technical specification logic", it cannot achieve functions such as automatic conversion of structural reinforcement. There are cost modeling software such as Guangliandaswell that "simplify the modeling function of structural reinforcement" to supplement this function. By integrating a digital system with BIM, the design process can "automatically complete tasks that require calculation and conversion" because it includes all relevant workflows and a "database and algorithm" that are logically edited according to technical specifications.

[0126] The following example illustrates the generation of structural steel reinforcement.

[0127] (1) Automatic conversion section: 1. Generate structural beam reinforcement drawings: According to the "Structural Code and Atlas 22G101-1" database, BIM software is developed using two methods: "using BIM plugins integrated with the system" or "using self-developed BIM software integrated with the system". The system directly reads all the results (including models and design specifications) of the structural analysis software (such as PKPM) to generate the structural beam reinforcement model, and classifies the relevant linear and textual data such as "axis lines, beam lines, reinforcement symbols, and specific reinforcement data" into the project database. 2. Analyze the beam configuration information: The beam type configuration information is given according to the beam code in the project database. For example, the code KL2(2A)300x650 indicates a floor frame beam numbered KL2 with a span of 2 spans, a cantilever at one end, and a cross-sectional size of 300x650 (see pages 1-22 and 1-23 of the "22G101-1" drawing set for details). 3. The minimum thickness of the beam protective layer is given: The prerequisite is that the architectural profession has defined the function of the building space where the steel bar is located as "bathroom" in the "Project Professional Classification Information and Drawings". Therefore, the environmental category of the structural components in the relevant area of ​​the bathroom can be further determined as "IIa" and the minimum thickness of the protective layer of the beam is 25mm (according to page 2-1 of "22G101-1" drawing set and Articles 3.5.2 and 8.2.1 of "Code for Design of Concrete Structures"). 4. Analysis of the reinforced concrete grade, steel reinforcement type, and seismic resistance grade of the beam: The system further automatically determines the "reinforced concrete strength grade, steel reinforcement strength grade, steel reinforcement type, and seismic resistance grade" of the beam based on the data in the project database. Ultimately, it can automatically determine the basic anchorage lengths of tensile reinforcement (Lab, LabE, La, LaE, etc.) for seismic design according to the "22G101-1" standard drawing. 5. Spatial positioning and anchorage length in the column (support): Based on the parameter definitions above, the "spatial location and anchorage length in the column (support)" of the steel bar in the specific beam section can be determined, thus generating the BIM detailed model. 6. Integration of Reinforcing Steel Related Data: and Figure 4 Similarly, data such as "design parameters and available suppliers" for steel bars can be found online; Note: This sixth step is a unique feature of the digital system and is the most valuable function for industry users (including all professions in construction engineering). 7. Follow-up work 7.1 Generate BIM versions of the "Design Specification" and various thematic descriptions: Within the system, through functions such as data linking, each professional work module generates corresponding BIM version of the "Design Specification" deliverables and thematic descriptions based on the generated BIM model; 7.2 Professional Collaboration: Within the system, through functions such as data linking, each discipline can revise and improve the results generated by the system and BIM at two points: "BIM version of the 'Design Specification' for each discipline is generated" and "Conversion results of different BIM software products are generated". The system will then uniformly confirm and deliver the "Detailed Design BIM Model". 7.3 (Possible) Conversion between BIM software: The system has a "data and algorithm" conversion function for BIM software products from different companies. Through data linking and other functions, it realizes the conversion between different BIM software products, and the result is a "detailed design BIM model". 7.4 Deliver a BIM with complete data: Within the system, by opening the BIM software, one can view the model and related data for the entire project lifecycle, and complete the entire process of "viewing and outputting" according to user needs.

[0128] 7.4.1 Review: Within the system, by opening the BIM software, you can view the model and related data for the entire project lifecycle; 7.4.2 Output: Based on user needs and permissions, the system aggregates existing data and then provides corresponding output data (forms) according to "system-provided or user-defined databases derived from standards and experience" for actual business applications. The following are two examples: "water pump" and "reinforcing steel". 1. Water supply pump: Users need to know the list of various models of "drainage pumps" for this project.

[0129] The system automatically provides all or part of the following data: "Project Name, Water Pump Model, Quantity, Location, Corresponding Sub-project, Project Data"; 2. Reinforcing steel: Users need to know two lists: "Reinforcing steel quantity" and "Detailed specifications".

[0130] The system automatically provides: (1) a bill of quantities for steel reinforcement (such as Table 9, additional item names, and other basic information); (2) steel reinforcement detailing results, which include: component name (such as KL2), steel reinforcement number (such as ①, ②), steel reinforcement specifications (diameter such as Φ8, Φ12, Φ25), steel reinforcement grade (such as HRB400, HRB500), single cutting length (cutting length accurate to millimeters), bending shape diagram (detail drawing, data from the drawing set screenshot), number of single pieces, total number of pieces, and total weight; The above are directly used for "cost calculation related to steel bars, steel bar procurement and processing production".

[0131] (2) Subsequent parts: Steps 3 to 6 of the steps and methods 1-1, including "generating the Design Specification and various thematic specifications, professional collaboration, (possibly) conversion between BIM software, and delivery of a BIM model with complete data", are the same as those in step 1-1 and are omitted.

[0132] 3.2.4.3 Method 2-3 Manual Operation The steps are to repeat the steps above, omitted.

[0133] This method is a supplementary approach, designed for "individual, small-scale, and unexpected" situations (after all, projects are subject to countless variations, and this accounts for less than 5%). The core of this method is to establish a link between the system and related BIM software for the uniquely added design content of the project, such as "structure, nodes, and equipment," including all data, i.e., "outcomes-data." (For example, if a project adds a decorative column for ethnic minorities, this is a rare case and accounts for a very small percentage; the user can simply assign the data for that decorative column.) 1. Complete the supplementation of the BIM model: Complete the drawing of the BIM family, attach its attributes, and configure related information; 2. Verification and Improvement: This paragraph is the same as the previous one.

[0134] 1. The system checks the attributes and related information in the BIM solution deliverables to see if they exist and where they come from (provided by the system). If there are any deficiencies, the system will provide a list and prompt the user to supplement them. 2. The user supplements and improves the information until the system has verified that everything is complete.

[0135] When an incomplete submission occurs, the system will prevent the submission from succeeding and will not allow you to proceed to the next step. 3. Follow-up work 3.1 Generate BIM versions of the "Design Specification" and various thematic descriptions: Within the system, through functions such as data linking, each professional work module generates corresponding BIM version of the "Design Specification" deliverables and thematic descriptions based on the generated BIM model; 3.2 Professional Collaboration: Within the system, through functions such as data linking, each discipline can revise and improve the results generated by the system and BIM at two points: "BIM version of the 'Design Specification' for each discipline is generated" and "Conversion results of different BIM software products are generated". The system will then uniformly confirm and deliver the "Detailed Design BIM Model". 3.3 (Possible) Conversion between BIM software: The system has a "data and algorithm" conversion function for BIM software products from different companies. Through data linking and other functions, it realizes the conversion between different BIM software products, and the result is a "detailed design BIM model". 3.4 Deliver a BIM with complete data: The system verification is complete.

[0136] By opening BIM software, you can see the model and related data for the entire project lifecycle; In user scenarios, data such as "detailed databases of water pumps and steel bars" can be obtained (viewed / pushed) and directly used for procurement by the e-commerce platform / suppliers.

[0139] The control module deploys an intelligent decision-making layer: when the pipeline stress exceeds the limit, it automatically generates three reinforcement schemes (adding supports / increasing the pipe diameter / adjusting the path) and pushes a comparison report.

[0140] It is understandable that this invention reduces emergency response time to 10-30 minutes, significantly reducing accident losses.

[0141] Understandably, the core value of this patent is user value, which is the scenario.
