Technical Field

[0001] This application relates to the field of auxiliary design technology for building structures, and in particular to a BIM-based auxiliary design method and system for prefabricated building structures. Background Technology

[0002] With the construction industry's pursuit of efficiency, environmental protection, and sustainable development, prefabricated buildings have received increasing attention due to their rapid construction and minimal environmental impact. Prefabricated buildings significantly improve construction efficiency while reducing construction waste and environmental impact by prefabricating components in factories and assembling them on-site. However, the design and construction of prefabricated buildings also face numerous challenges. For example, the quality of prefabricated buildings is highly dependent on the accuracy of the design and the manufacturing quality of the components. Traditional design and construction methods struggle to effectively guarantee the compatibility of components and the quality of construction. In summary, existing prefabricated building technologies suffer from the inability to accurately calculate and plan the various components during the design phase, resulting in the inability to obtain highly accurate prefabricated components, which affects subsequent assembly and construction.

[0003] In summary, existing traditional two-dimensional design methods are insufficient to meet the high precision requirements of prefabricated buildings. The quality of prefabricated buildings is highly dependent on the accuracy of the design and the manufacturing quality of the components. Therefore, existing prefabricated buildings have technical problems that can easily lead to design errors and construction inaccuracies. Summary of the Invention

[0004] The purpose of this application is to provide a BIM-based auxiliary design method and system for prefabricated building structures, in order to solve the problem that existing traditional two-dimensional design methods are difficult to meet the high precision requirements of prefabricated buildings. The quality of prefabricated buildings is highly dependent on the accuracy of the design and the manufacturing quality of the components. Therefore, existing prefabricated buildings have technical problems that can easily lead to design errors and construction accuracy issues.

[0005] In view of the above problems, this application provides a BIM-based auxiliary design method and system for prefabricated building structures.

[0006] Firstly, this application provides a BIM-based auxiliary design method for prefabricated building structures. This method is implemented through a BIM-based auxiliary design system for prefabricated building structures. The method includes: constructing a target component set for a target building; obtaining first multi-dimensional requirements for a first component in the target component set, where the first multi-dimensional requirements include first functional requirements and first shape requirements; creating a first three-dimensional prefabricated component of the first component based on the first functional requirements and the first shape requirements, and constructing a target three-dimensional component library; pre-assembling the target three-dimensional component library to obtain an initial building model of the target building, and parametrically adjusting the initial building model to obtain a target design model; activating a BIM-assisted detector to perform collision detection on the target design model to obtain target detection results, where the target detection results include first conflict information of a first adjacent component group; if a first conflict index obtained by analyzing the first conflict information meets a predetermined conflict index threshold, generating a target design plan based on the target design model; and performing on-site assembly construction of the target building according to the target design plan.

[0007] Secondly, this application also provides a BIM-based prefabricated building structure auxiliary design system for executing a BIM-based prefabricated building structure auxiliary design method as described in the first aspect. The BIM-based prefabricated building structure auxiliary design system includes: a component requirement acquisition module for assembling a target component set for a target building and acquiring first multi-dimensional requirements for a first component in the target component set, the first multi-dimensional requirements including first functional requirements and first shape requirements; a component library assembly module for creating a first three-dimensional prefabricated component of the first component based on the first functional requirements and the first shape requirements, and assembling a target three-dimensional component library; and obtaining a design model. The system comprises the following modules: a model module for pre-assembling the target 3D component library to obtain an initial building model of the target building, and parametrically adjusting the initial building model to obtain a target design model; a collision detection module for activating a BIM-assisted detector to perform collision detection on the target design model to obtain target detection results, the target detection results including first conflict information of a first adjacent component group; a building design generation module for generating a target design plan based on the target design model if the first conflict index obtained from analyzing the first conflict information meets a predetermined conflict index threshold; and a building assembly and construction module for performing on-site assembly and construction of the target building according to the target design plan.

[0008] One or more technical solutions provided in this application have at least the following technical effects or advantages: The process involves: 1) Assembling a target building component set and obtaining the first multi-dimensional requirements of the first component in the target component set, including first functional requirements and first shape requirements; 2) Creating a first three-dimensional prefabricated component of the first component based on the first functional and shape requirements, and building a target three-dimensional component library; 3) Pre-assembling the target three-dimensional component library to obtain an initial building model of the target building, and parametrically adjusting the initial building model to obtain a target design model; 4) Activating a BIM-assisted detector to perform collision detection on the target design model to obtain target detection results, including first conflict information of the first adjacent component group; 5) If the first conflict index obtained from analyzing the first conflict information meets a predetermined conflict index threshold, generating a target design plan based on the target design model; and 6) Performing on-site assembly construction of the target building according to the target design plan. In other words, the process begins by assembling a component set for the target building and obtaining the functional and shape requirements of the first component. Based on these requirements, three-dimensional prefabricated components are created and a target three-dimensional component library is built. Subsequently, the target three-dimensional component library is pre-assembled to obtain an initial building model, and parametrically adjusted to generate a target design model. A BIM-assisted detector is then used to perform collision detection on the target design model, and conflict information is analyzed. If the conflict index meets a predetermined threshold, a target design plan is generated, and on-site assembly construction is carried out accordingly. Through the 3D visualization and parametric design capabilities of BIM technology, designers can quickly adjust and optimize components during the design phase, reducing design errors and improving design quality. Furthermore, collision detection and correction can identify and resolve spatial conflicts between components in advance, ensuring the compatibility of components during actual assembly and achieving the goal of improving construction quality.

[0012] This application provides a BIM-based auxiliary design method and system for prefabricated building structures. It addresses the challenge of existing traditional two-dimensional design methods failing to meet the high precision requirements of prefabricated buildings. The quality of prefabricated buildings heavily depends on the accuracy of the design and the manufacturing quality of the components; therefore, existing prefabricated building methods are prone to design errors and construction inaccuracies. Through the three-dimensional visualization and parametric design capabilities of BIM technology, designers can quickly adjust and optimize components during the design phase, reducing design errors and improving design quality. Furthermore, collision detection and correction can identify and resolve spatial conflicts between components in advance, ensuring the compatibility of components during actual assembly and achieving the goal of improving construction quality.

[0014] Example 1, please refer to the appendix. Figure 1 This application provides a BIM-based auxiliary design method for prefabricated building structures. The method is applied to a BIM-based auxiliary design system for prefabricated building structures, and specifically includes the following steps: Step P10: Assemble the target component set of the target building, and obtain the first multi-dimensional requirements of the first component in the target component set. The first multi-dimensional requirements include the first functional requirements and the first shape requirements. Specifically, the design involves assembling a component set for the target building and setting multi-dimensional requirements for key components to ensure they meet design standards in both function and form. First, a target component set for the target building is established, forming the foundation of the entire design process. This involves systematically organizing and categorizing all necessary components for the building, facilitating subsequent detailed design and construction. Next, the first multi-dimensional requirements for the first component in the target component set are obtained, encompassing both functional and aesthetic aspects. Functional requirements ensure the component's performance and utility in actual use, while aesthetic requirements guarantee that the component's size and shape perfectly match the architectural design. By clarifying these multi-dimensional requirements, designers can precisely define the characteristics of each component, providing clear guidance for subsequent 3D modeling and construction. Furthermore, this multi-dimensional requirement setting reflects the design's attention to detail and control over overall design quality.

[0015] In summary, by constructing a target component set and clarifying its multi-dimensional requirements, refined management and precise design of building components are achieved. By defining functional and aesthetic requirements, the adaptability of components and the accuracy of design can be effectively improved, thereby enabling efficient and high-quality construction project implementation.

[0016] Step P20: Based on the first functional requirements and the first shape requirements, create the first three-dimensional prefabricated component of the first component, and build a target three-dimensional component library; Specifically, by defining precise functional and shape requirements, three-dimensional prefabricated components are created and a target three-dimensional component library is built, providing standardized and modular component support for subsequent design and construction of building projects. First, based on the primary functional and shape requirements, a first three-dimensional prefabricated component is created. Through 3D modeling technology, designers can intuitively present the shape, size, and structural features of the component, thereby verifying its applicability in a virtual environment in advance. Next, the created first three-dimensional prefabricated component is incorporated into the target three-dimensional component library. The establishment of this component library provides standardized modules for subsequent building model construction, making the design process more efficient and flexible. Furthermore, the component library facilitates unified management and optimization of components, further improving the accuracy and efficiency of the design.

[0017] In summary, by creating 3D prefabricated components based on functional and shape requirements and establishing a target 3D component library, standardized and modular design of building components has been achieved. This not only improves design efficiency but also ensures the accuracy and consistency of components, laying the foundation for efficient and high-quality building construction.

[0018] Step P30: Pre-assemble the target 3D component library to obtain the initial building model of the target building, and perform parametric adjustments on the initial building model to obtain the target design model; Specifically, by pre-assembling and parametrically adjusting the target 3D component library, a target building model that meets the design requirements is generated.

[0019] First, the target 3D component library is pre-assembled, a crucial step in generating the initial model of the target building. By virtually assembling pre-created 3D prefabricated components according to design logic, designers can initially construct the overall framework of the building in a virtual environment. This process allows the design team to visually observe the overall layout of the building and the relationships between components at an early stage, thereby identifying potential design problems in a timely manner. Next, the initial building model is parametrically adjusted. Parametric adjustment is one of the highlights of this approach, allowing designers to quickly optimize the model by modifying key parameters (such as size, shape, and position) to better meet design requirements. Furthermore, parametric adjustment enables dynamic updates to the model; when a parameter changes, related components and structures automatically adjust, significantly improving design efficiency. Clearly, this process not only enhances the model's flexibility but also facilitates subsequent design optimization and construction preparation.

[0020] In summary, by pre-assembling and parametrically adjusting the target 3D component library, an efficient transformation from the initial building model to the target design model was achieved. This process not only enables the virtual assembly and optimization of building components but also enhances the model's flexibility and adaptability through parametric adjustments, thus providing strong support for efficient design and precise construction of building projects.

[0021] Step P40: Activate the BIM-assisted detector to perform collision detection on the target design model to obtain the target detection result, which includes the first conflict information of the first adjacent component group; Specifically, collision detection of the target design model is performed by activating the BIM-assisted detector in order to identify and resolve potential conflicts in the design.

[0022] First, the BIM-assisted detector is activated. This detector performs comprehensive clash detection on the target design model, including not only contour clashes between components but also potential conflicts between internal reinforcing bars and embedded parts. This allows design issues to be identified early in the virtual environment, preventing rework and delays during construction due to design conflicts. Next, the clash detection results generate a target detection report, containing information on the first clashes between adjacent component groups. This clash information provides clear guidance for design optimization, enabling designers to adjust and modify component designs based on the detection results, ensuring that components are problem-free during manufacturing and installation.

[0023] In summary, using BIM-assisted detectors to perform clash detection on the target design model enables efficient identification and resolution of design conflicts. Its technical objective is to improve the accuracy and reliability of the design, reduce potential problems and cost increases during the construction phase, thereby ensuring the smooth implementation of building projects.

[0024] Step P50: If the first conflict index obtained by analyzing the first conflict information meets the predetermined conflict index threshold, generate a target design plan based on the target design model; Specifically, the process involves analyzing the initial conflict information from collision detection results and generating a target design plan based on a preset conflict index threshold. Analyzing the initial conflict information is a crucial step in ensuring the reliability of the design model. By evaluating the conflict information, the severity of the conflict can be quantified, generating a first conflict index. This index is an important indicator for measuring potential problems in the design model, reflecting the degree of spatial and functional conflict between components. Next, when the first conflict index meets the predetermined conflict index threshold, a target design plan is generated based on the target design model. If the conflict index is within an acceptable range, a construction plan can be generated to guide subsequent on-site construction.

[0025] In summary, by analyzing and quantifying the primary conflict information, a target design plan is generated, ensuring the feasibility of the design model. By quantifying the severity of the conflict and developing a construction plan accordingly, risks during the construction phase are effectively reduced, improving the efficiency and quality of the construction project. Through scientific conflict assessment and plan generation, risks during the construction phase are reduced, and the efficiency and quality of the construction project are improved. Clearly, this process not only enhances the reliability of the design but also provides a clear basis for the construction phase.

[0026] Step P60: Perform on-site assembly and construction of the target building according to the target design plan.

[0027] Specifically, this contingency plan, generated after detailed clash detection and conflict analysis, includes crucial information such as the precise dimensions, installation locations, and construction sequences of building components. This information provides clear guidance for on-site construction, ensuring the construction team operates according to the established design requirements. Next, on-site assembly construction proceeds according to the target design contingency plan. This process requires the construction team to strictly follow the instructions in the plan, including component transportation, installation, and connection. In this way, the construction team can efficiently complete the building assembly work on-site, reducing additional costs and time delays caused by temporary adjustments. Furthermore, the implementation of the contingency plan ensures the standardization and normalization of the construction process, thereby improving construction quality. By applying the clash-detected and optimized design contingency plan to on-site construction, accuracy and efficiency are ensured, while reducing construction delays and cost increases caused by design issues, thus improving the overall quality and implementation efficiency of the building project.

[0028] Furthermore, the target 3D component library is pre-assembled to obtain an initial architectural model of the target building, and the initial architectural model is parametrically adjusted to obtain a target design model, including: Extract the first non-geometric requirement from the first multidimensional requirement; Read the predetermined material property index, and iterate through the first non-geometric requirement based on the predetermined material property index to obtain the first material property parameter; Read the predetermined mechanical performance index, and traverse the first non-geometric requirement based on the predetermined mechanical performance index to obtain the first mechanical performance parameter; Read the predetermined durability index, and iterate through the first non-geometric requirement based on the predetermined durability index to obtain the first durability parameter; Based on the first material property parameters, the first mechanical property parameters, and the first durability parameters, a first parameterized benchmark is constructed, and a target parameterized benchmark for the target building is formed. The initial building model is parametrically adjusted using the target parametric benchmark as a constraint to obtain the target design model.

[0029] Specifically, by systematically analyzing the non-geometric requirements in the first multidimensional requirement and combining them with material properties, mechanical properties, and durability indicators, a target parameterized benchmark for the target building is constructed.

[0030] First, the first non-geometric requirement is extracted from the first multidimensional requirement. This requirement typically involves non-geometric attributes such as the functionality and performance indicators of the component. These non-geometric requirements are key factors in ensuring that the component meets specific functions and performance requirements in actual use. Next, predetermined material property indicators are read, and the first non-geometric requirement is iterated based on these indicators to obtain the first material property parameters. This process ensures that the material selection of the component meets the design requirements and also provides a foundation for subsequent mechanical performance and durability analysis. In addition, by reading predetermined mechanical performance indicators and durability indicators, and iterating through the first non-geometric requirement respectively, the first mechanical performance parameters and the first durability parameters are obtained. The acquisition of these parameters further refines the performance requirements of the component, ensuring its reliability and durability in actual use. Based on the first material property parameters, first mechanical performance parameters, and first durability parameters obtained from the above analysis, the scheme establishes the first parametric benchmark, and further forms the target parametric benchmark for the target building. This benchmark provides clear constraints for the parametric adjustment of the building model. Finally, with the target parametric benchmark as a constraint, the initial building model is parametrically adjusted to obtain the target design model. This process not only optimizes the design of the architectural model, but also ensures that the model meets non-geometric requirements while possessing good material properties, mechanical properties, and durability.

[0031] In summary, by conducting an in-depth analysis of the non-geometric requirements in the first multidimensional requirement, and by constructing a target parameterized benchmark in combination with material properties, mechanical properties, and durability indicators, the building model was precisely optimized. This ensured that the building components fully met the design requirements in terms of function and performance. Furthermore, the design of the building model was optimized through parameterized adjustments, providing a solid technical foundation for high-quality building design and construction.

[0032] Furthermore, the predetermined material property indicators include at least density, thermal conductivity, and corrosion resistance; the predetermined durability indicators include at least strength, stiffness, and stability; and the predetermined durability indicators include at least anti-aging and anti-wear properties.

[0033] Specifically, predetermined material properties should include at least density, thermal conductivity, and corrosion resistance. These are key parameters for evaluating the basic performance of building materials. Density determines the material's weight and structural load-bearing capacity; thermal conductivity affects the material's insulation performance, which is crucial for energy-efficient building design; corrosion resistance ensures the material maintains stable performance under different environmental conditions, extending its service life. By clearly defining these material properties, designers can accurately select materials that meet the requirements, laying the foundation for subsequent component design. Predetermined durability indicators include strength, stiffness, and stability. These indicators directly relate to the reliability and safety of building components during long-term use. Strength reflects the material's ability to resist external forces; stiffness determines the degree of deformation of the component under stress; stability ensures that the component maintains structural integrity during long-term use and does not undergo uncontrollable changes due to environmental or external forces. Furthermore, predetermined durability indicators should include at least anti-aging and anti-wear properties. Anti-aging ensures the material maintains its performance even after long-term exposure to natural environments (such as sunlight and temperature changes); anti-wear ensures that the component does not prematurely fail under frequent use or friction conditions. The definition of these durability indicators provides a quantitative standard for the long-term performance evaluation of building components.

[0034] In summary, by clearly defining the specific content of predetermined material property indicators and predetermined durability indicators, a scientific basis is provided for the design and performance evaluation of building components. This ensures that building components meet high standards in terms of material selection and durability, thereby improving the overall quality and service life of buildings.

[0035] Furthermore, if the first conflict index obtained from analyzing the first conflict information meets a predetermined conflict index threshold, a target design plan is generated based on the target design model, including: Read the conflict assessment function and analyze the first conflict information according to the conflict assessment function to obtain the first conflict index; The expression for the conflict evaluation function is as follows: ; Characterizing the first adjacent component group The first conflict index. Characterizing the first adjacent component group The maximum possible conflict index, Characterizing the first adjacent component group The The degree of conflict of this type of conflict Characterizing the first The conflict weight of each type of conflict.

[0036] Specifically, the conflict assessment function is read, and the first conflict information is analyzed based on the conflict assessment function to obtain the first conflict index. The expression for the conflict assessment function is as follows: ; Characterizing the first adjacent component group The first conflict index. Characterizing the first adjacent component group The maximum possible conflict index, Characterizing the first adjacent component group The The degree of conflict of this type of conflict Characterizing the first The conflict weights are assigned to various conflict types, which may include geometric collisions, functional collisions, and construction sequence conflicts.

[0037] Furthermore, if the first conflict index obtained from analyzing the first conflict information meets a predetermined conflict index threshold, generating a target design plan based on the target design model further includes: Obtain the first collision component information of the first adjacent component group; Based on the first mapping relationship between the first adjacent component group, the first collision component information, and the first conflict index, a first visual detection result is obtained; A target visual detection map of the target design model is generated based on the first visual detection result; The information of the first collision component includes the number, position, size, and material of the first adjacent component group.

[0038] Specifically, through detailed analysis and visualization of collision detection results, complex collision information is transformed into intuitive visual detection diagrams, thereby providing clear guidance for design optimization and construction preparation.

[0039] First, by acquiring the information of the first colliding component in the first adjacent component group, foundational data is provided for subsequent analysis. This information includes the component's number, location, size, and material—details crucial for assessing collision issues. The number helps identify specific components, location and size directly relate to the geometric features of the collision, while material properties influence the physical consequences. Acquiring this information ensures the accuracy and relevance of subsequent analysis. Next, based on the mapping relationship between the first adjacent component group, the first colliding component information, and the first conflict index, the first visual detection result is obtained. By combining collision information with the conflict index, designers can quantify the severity of collisions and present it intuitively through visualization. This mapping relationship not only improves the efficiency of problem identification but also provides a clear direction for design optimization. Finally, a target visual detection map of the target design model is generated based on the first visual detection result. This visual detection map is the final output of the solution, transforming complex collision information into an intuitive image, enabling the design team to more clearly understand the distribution and severity of collision problems. This visualization method not only enhances the design team's understanding of the problem but also promotes communication and collaboration among team members. By using target visual inspection maps, designers can adjust design models more efficiently and reduce potential construction risks.

[0040] In summary, by acquiring collision component information, establishing mapping relationships, and generating visual detection maps, effective analysis and visualization of collision detection results are achieved, improving the efficiency and accuracy of the design phase. Furthermore, visualization enhances the design team's understanding and communication capabilities regarding potential problems, ensuring the reliability and feasibility of the design model.

[0041] Furthermore, if the first conflict index obtained by analyzing the first conflict information does not meet the predetermined conflict index threshold, a correction instruction is issued, and the first adjacent component group is corrected and adjusted based on the correction instruction.

[0042] Specifically, the system dynamically evaluates and corrects conflicts identified during collision detection. When the first conflict index does not reach a predetermined threshold, a correction command is issued, and the conflicting component group is adjusted accordingly to ensure the accuracy and feasibility of the design model. If the first conflict index does not reach the predetermined threshold, it indicates that the current design has unacceptable conflicts and requires correction. At this point, the system issues a correction command, which serves as the trigger mechanism for subsequent adjustment processes, ensuring that the design team can respond and resolve issues promptly. Next, the first adjacent component group is corrected and adjusted based on the correction command. By adjusting the position, size, shape, or other relevant parameters of the conflicting components, designers can eliminate or reduce conflicts. Specific methods of correction and adjustment may include rearranging components, modifying component geometry, or adjusting material properties. By analyzing the conflict index and issuing correction commands, the conflicting component group is dynamically adjusted to ensure the accuracy and feasibility of the design model.

[0043] Furthermore, if the first conflict index obtained from analyzing the first conflict information meets a predetermined conflict index threshold, a target design plan is generated based on the target design model, including: Generate a target production list based on the target design model; Generate a target installation list based on the target design model; The target production list and the target installation list together constitute the target design plan.

[0044] Furthermore, the target production list includes component geometry, component material specifications, component quantity, and component processing requirements, while the target installation list includes component installation location, component connection method, and component installation sequence.

[0045] Specifically, a target production list and a target installation list are generated from the target design model and integrated into a target design plan. First, a target production list is generated based on the target design model. This list details the production requirements for all components in the building project, including their dimensions, materials, shapes, and processing techniques. The target production list details the geometric dimensions, material specifications, quantities, and processing requirements of each component. Geometric dimensions are the foundation for component manufacturing, ensuring that each component meets design requirements in shape and size; material specifications clarify the type and performance standards of the materials used, which are crucial for the component's quality and durability; accurate quantity statistics avoid overproduction or underproduction; and processing requirements cover technical details that require special attention during manufacturing, such as precision requirements and surface treatment. The integration of this information enables the production process to complete component manufacturing tasks efficiently and accurately. Generating the target production list is a key step in transforming the design model into actual production tasks, providing clear guidance for the production process and ensuring that each component is manufactured precisely according to design requirements.

[0046] Next, a target installation list is generated based on the same target design model. This list focuses on the construction phase, detailing the installation sequence, connection methods, installation locations, and required tools and equipment for each component. The generation of the target installation list allows the construction team to clearly understand the installation requirements of each component, enabling them to complete the assembly task efficiently and accurately. The target installation list focuses on the construction phase, detailing the installation location, connection method, and installation sequence of each component. Installation location information ensures that construction personnel can accurately place each component in the correct position; connection methods clarify the connection methods between components, such as welding, bolting, or other special connection methods, which are crucial for the stability of the components and the reliability of the overall structure; the installation sequence provides the construction team with clear guidance on the construction process, avoiding construction delays or structural problems caused by improper installation sequence.

[0047] Furthermore, the target production list and the target installation list together constitute the target design plan. This plan serves as a bridge between the design model and actual construction, encompassing not only the production details of the components but also key information during the installation process. This ensures close coordination between production and installation, reducing construction delays and cost increases caused by information inconsistencies.

[0048] In summary, by generating target production and installation lists based on the target design model and integrating them into a target design plan, efficient transformation from design to construction is achieved. This ensures that the production and installation of building components accurately meet design requirements, thereby improving the overall efficiency and quality of the construction project.

[0049] Furthermore, before carrying out on-site assembly construction of the target building according to the target design plan, the process also includes: Activate the green assessor, which contains an energy consumption assessment plan and an environmental impact assessment plan; The target design plan is feature-collected based on the energy consumption-related features in the energy consumption assessment plan to obtain energy consumption feature parameters. Based on the environmental impact-related characteristics in the environmental impact assessment plan, feature collection is performed on the target design plan to obtain environmental impact characteristic parameters; The target green index of the target design plan is obtained by normalizing the energy consumption characteristic parameters and the environmental impact characteristic parameters.

[0050] Specifically, by activating the green assessor, a comprehensive assessment of the energy consumption and environmental impact of the target design plan is conducted, and the target green index is obtained through normalization calculation. Activating the green assessor is the initial step in this process. The green assessor contains both energy consumption assessment plans and environmental impact assessment plans, both crucial tools for evaluating the green performance of building projects. The energy consumption assessment plan focuses on the energy consumption of the building during its use, while the environmental impact assessment plan emphasizes the potential impact of the building project on the surrounding environment. By activating the green assessor, the green performance of the target design plan can be systematically evaluated.

[0051] Next, the design plan collects features based on the energy consumption-related characteristics in the energy consumption assessment plan, obtaining energy consumption characteristic parameters. This process extracts specific indicators related to energy consumption (such as energy consumption and energy utilization efficiency) to provide data support for subsequent energy consumption assessments. Similarly, the design plan collects features based on the environmental impact-related characteristics in the environmental impact assessment plan, obtaining environmental impact characteristic parameters. These characteristic parameters may include pollutant emissions and resource utilization efficiency, used to assess the potential environmental impact of the construction project.

[0052] Furthermore, to enable the comparison and comprehensive analysis of energy consumption and environmental impact characteristic parameters within the same evaluation system, the plan normalizes these parameters. Normalization is a common data processing method that converts parameters of different dimensions and orders of magnitude into dimensionless standardized values, thereby obtaining the target green index of the design plan. This index is a comprehensive indicator for measuring the green performance of a building project, and can intuitively reflect the project's performance in terms of energy consumption and environmental impact.

[0053] Finally, by calculating the target green index, the design team can quantitatively assess the green performance of the target design plan. This index not only provides a clear direction for design optimization but also offers a scientific basis for the project's sustainable development. Clearly, this process reflects the plan's emphasis on green building principles, using scientific evaluation methods to promote the full consideration of energy conservation and environmental protection factors in the design phase of building projects.

[0054] In summary, by activating the green assessment tool, the energy consumption and environmental impact characteristics of the target design plan are collected, and the target green index is calculated through normalization, thus achieving a quantitative assessment of the green performance of building projects. Quantifying the green performance of building projects provides a scientific basis for design optimization, thereby promoting the development of building projects towards a more environmentally friendly and energy-efficient direction and achieving sustainable development goals.

[0055] In summary, the BIM-based prefabricated building structure auxiliary design method provided in this application has the following technical effects: The process involves: 1) Assembling a target building component set and obtaining the first multi-dimensional requirements of the first component in the target component set, including first functional requirements and first shape requirements; 2) Creating a first three-dimensional prefabricated component of the first component based on the first functional and shape requirements, and building a target three-dimensional component library; 3) Pre-assembling the target three-dimensional component library to obtain an initial building model of the target building, and parametrically adjusting the initial building model to obtain a target design model; 4) Activating a BIM-assisted detector to perform collision detection on the target design model to obtain target detection results, including first conflict information of the first adjacent component group; 5) If the first conflict index obtained from analyzing the first conflict information meets a predetermined conflict index threshold, generating a target design plan based on the target design model; and 6) Performing on-site assembly construction of the target building according to the target design plan. In other words, the process begins by assembling a component set for the target building and obtaining the functional and shape requirements of the first component. Based on these requirements, three-dimensional prefabricated components are created and a target three-dimensional component library is built. Subsequently, the target three-dimensional component library is pre-assembled to obtain an initial building model, and parametrically adjusted to generate a target design model. A BIM-assisted detector is then used to perform collision detection on the target design model, and conflict information is analyzed. If the conflict index meets a predetermined threshold, a target design plan is generated, and on-site assembly construction is carried out accordingly. Through the 3D visualization and parametric design capabilities of BIM technology, designers can quickly adjust and optimize components during the design phase, reducing design errors and improving design quality. Furthermore, collision detection and correction can identify and resolve spatial conflicts between components in advance, ensuring the compatibility of components during actual assembly and achieving the goal of improving construction quality.
