Description

Technical Field

[0001] This invention belongs to the field of architectural design and relates to a dynamic adaptation design method for planning indicators of Beijing courtyard houses based on parametric modeling. Background Technology

[0002] As an outstanding representative of traditional Chinese architecture, the courtyard house carries rich historical and cultural connotations. Its unique architectural style and layout have been passed down for hundreds of years, making it an important part of the urban landscape. Traditional courtyard house design follows a fixed process: first, the building axis is delineated as the foundation; second, the dimensions of the bays and depth are determined based on the axis; then, the roof's eaves shape is determined according to the bays and depth, and the position and dimensions of the raised beam structure and purlins are located; finally, the roof construction is completed to finalize the preliminary design. In this model, the axis is central, and key planning indicators such as building area and eaves height are derived through complex calculations after the axis is determined.

[0003] However, contemporary core area planning and management places greater emphasis on the rational use of space and overall aesthetic control, often setting inviolable red lines for building area and eaves height. This poses a severe challenge to traditional design methods: if the design process starting from the axis ultimately yields indicators that do not meet planning requirements, it is necessary to go back to the axis stage for modifications, resulting in a large amount of work being scrapped and restarted, significantly extending the design cycle and increasing costs. In addition, during the refinement of the design, it is difficult to cope with dynamic changes in existing conditions (such as changes in courtyard red lines) and functional requirements (such as the transformation from residential to cultural exhibition). Traditional design lacks a real-time monitoring mechanism, making it impossible to know in a timely manner whether key indicators have changed or still meet requirements, posing a risk of indicators getting out of control and affecting project approval and progress.

[0004] In conclusion, traditional design methods suffer from drawbacks under contemporary planning and control, such as long design cycles, weak adaptability to changes, and lack of real-time monitoring and feedback of planning indicators. There is an urgent need for a new design method and system to solve these problems and achieve the adaptive inheritance and development of traditional courtyard architecture under the requirements of modern urban planning. Summary of the Invention

[0005] To address the problems existing in the background technology, this invention proposes a dynamic adaptation design system and method for courtyard house planning indicators based on parametric modeling.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A dynamic adaptation design method for planning indicators of Beijing courtyard houses based on parametric modeling includes: S1. Obtain input information including building axis vector information, building facade form, roof ridge form, eaves height, and preset parameters; S2. Generate virtual building sections based on input information and traditional courtyard house architectural style rules; S3. Load the preset planning indicators, and compare and analyze the data corresponding to the virtual profile with the preset planning indicators in real time to determine whether they meet the requirements. S4. If the virtual profile does not meet the preset planning indicators, output a prompt message and return to the step of receiving input information to adjust the relevant parameters; If the virtual profile meets the preset planning indicators, a three-dimensional building model is generated based on the virtual profile; S5. If the input information is modified, repeat steps S2 to S4 to update the virtual profile and 3D building model, and provide real-time feedback on changes in planning indicators.

[0007] Furthermore, the preset parameters include at least the specific values ​​of eaves height, eaves depth, wall thickness, roof construction thickness, and platform height.

[0008] Further, S2 includes: The roof slope and height are determined based on the traditional rules of roof folding in courtyard houses and the key parameters of eaves depth and roof construction thickness in the input information. The wall thickness and platform height parameters in the input information are used to determine the cross-sectional shape of the main building and foundation.

[0009] Furthermore, the preset planning indicators in S3 are generated based on the urban planning requirements and relevant laws and policies of the area where the courtyard house is located; The preset planning indicators include at least the building area, the height of the front and rear eaves, and the height of the roof ridge.

[0010] Furthermore, the real-time comparison and analysis of the data corresponding to the virtual profile with the preset planning indicators in step S3 includes: Calculate the actual building area corresponding to the virtual cross-section, and measure the actual eaves height in the virtual cross-section.

[0011] Furthermore, the building facade is one of the following: double-sided openwork, eaves extending from the rear, or a closed rear eaves.

[0012] Furthermore, the ridge form is either a plain ridge or a saddle ridge.

[0013] Furthermore, the prompt information in S4 includes the name of the planning indicator that exceeds the limit and the difference value.

[0014] On the other hand, the present invention provides a design system for a dynamic adaptation design system of courtyard house planning indicators that implements parametric modeling of any of the above methods, comprising: A data input module for receiving input information including building axis vector information, building facade form, roof ridge form, eave height, and preset parameters; A parametric design module connected to the data input module, generating a building virtual section based on the input information received by the data input module and the traditional quadrangle courtyard building standard rules; A planning index matching module connected to the parametric design module, loading preset planning indexes, and performing real-time comparison and analysis on the data corresponding to the virtual section and the preset planning indexes; A feedback prompt module connected to the planning index matching module, used for outputting prompt information when the planning index matching module finds differences in the comparison and analysis; A three-dimensional modeling module connected to the planning index matching module, used for generating a three-dimensional building model based on the virtual section when the virtual section meets the preset planning indexes.

[0015] Furthermore, the data input module includes: A building axis vector information input unit for receiving the building axis vector information input by the user; A building facade form selection unit for providing and receiving the user's selection of facade forms such as double-sided transparent, back old eave out, and back sealed rear eave; A roof ridge form selection unit for providing and receiving the user's selection of roof ridge forms such as clear water ridge and saddle ridge; An eave height input unit for providing and accepting the user's input of the key eave height and defining the input eave height as the front eave or the rear eave; An other key parameter input unit for receiving the key parameter values input by the user, where the key parameters at least include eave depth, wall thickness, roof construction thickness, and platform height.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This application subverts the traditional quadrangle courtyard design process, and realizes multi-factor linkage design and real-time monitoring of planning indexes through parametric modeling technology. The system synchronously integrates the axis, facade, roof ridge, and key parameters at the input stage, automatically generates a virtual section and immediately compares the planning indexes, and gives real-time feedback adjustment suggestions when exceeding the limit; after confirming compliance, a three-dimensional model is dynamically generated. This mechanism effectively avoids the axis-level backtracking and repeated modifications caused by non-compliance of traditional designs, significantly shortening the design cycle; at the same time, it accurately quantifies the evaluation indexes, supports the automatic update of the model and the re-verification of indexes after parameter adjustment, greatly improving the design efficiency, scientificity, and dynamic adaptability, and ensuring that the quadrangle courtyard design strictly meets the modern planning control requirements while inheriting the traditional standards.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figure 1 As shown, a dynamic adaptation design method for planning indicators of Beijing courtyard houses based on parametric modeling includes: S1. Obtain input information including building axis vector information, building facade form, roof ridge form, eaves height, and preset parameters.

[0020] S2. Generate a virtual cross-section of the building based on the input information and the traditional courtyard house architectural style rules.

[0021] S3. Load the preset planning indicators, compare and analyze the data corresponding to the virtual profile with the preset planning indicators in real time, and determine whether they meet the requirements.

[0022] S4. If the virtual profile does not meet the preset planning indicators, output a prompt message and return to the step of receiving input information to adjust the relevant parameters.

[0023] If the virtual profile meets the preset planning indicators, a three-dimensional building model is generated based on the virtual profile.

[0024] S5. If the input information is modified, repeat steps S2 to S4 to update the virtual profile and 3D building model, and provide real-time feedback on changes in planning indicators.

[0025] First, the data input module receives and integrates various design-related information.

[0026] By inputting architectural axis vector information, designers can accurately input the architectural axis vector information using professional drawing software or the system's built-in drawing tools. This information determines the basic layout and orientation of the courtyard house, providing a spatial reference for subsequent design. For example, in a typical courtyard house design, designers can draw east-west or north-south architectural axes based on site conditions and design intentions, clarifying the main orientation and general outline of the building.

[0027] For building facade selection, the system provides an intuitive user interface, displaying three facade options—double-sided openness, projecting eaves on the rear, and enclosed rear eaves—through drop-down menus or buttons. Designers make their selections based on project requirements, and the system records the selected information in real time. For example, if the building is located next to a city street, designers can choose a facade with enclosed rear eaves or projecting eaves; if the building is located in a courtyard and emphasizes the integration of the front and rear landscapes, a double-sided openness facade is preferable.

[0028] The roof ridge style selection is also presented visually in the user interface, offering two options: exposed ridge and saddle ridge, for designers to choose from. Designers can view renderings or brief descriptions of different ridge styles to make a decision. After selection, the system incorporates the roof ridge style information into the design data system.

[0029] For key parameter input, designers enter specific values ​​for critical parameters such as eaves height, eaves depth, wall thickness, roof construction thickness, and platform height into designated data input boxes. The system performs format checks and validity verification on the input values ​​to ensure data accuracy and validity.

[0030] Based on the input information provided by the data input module and the traditional courtyard house architectural style rules, a highly correlated and dynamically adjustable parametric model is constructed using parametric modeling technology to generate a virtual building section.

[0031] Based on the design rules and parameter relationships of traditional courtyard house architecture, the module generates virtual cross-sections of the building. During the generation process, the structural mechanics principles, spatial layout requirements, and parameter constraints are considered to accurately simulate the cross-sectional shape of the courtyard house under different parameter settings. For example, based on the relevant rules of roof folding, combined with parameters such as eaves depth and roof thickness, the roof slope and height are determined, thus generating an accurate roof cross-sectional shape. Simultaneously, based on parameters such as wall thickness and platform height, the cross-sectional shapes of the main structure and foundation are determined.

[0032] Load preset planning indicators, and compare and analyze the data corresponding to the virtual profile with the preset planning indicators in real time to determine whether they meet the requirements.

[0033] The system loads pre-set planning indicators from its database, such as building area, eaves height, and building density. These indicators are set according to the urban planning requirements and relevant laws and policies of Beijing's core area to ensure that the design scheme complies with local planning control standards.

[0034] The module compares the data corresponding to the virtual profile generated by the parametric design module with the loaded planning indicators one by one. Through precise numerical calculations and logical judgments, it determines whether the virtual profile meets the planning indicator requirements. For example, it calculates the building area corresponding to the virtual profile and compares it with the preset building area indicator; it measures the eaves height in the virtual profile and compares it with the specified eaves height red line. If a planning indicator is found to be non-compliant, the module quickly detects the discrepancy and transmits the name of the planning indicator exceeding the limit and the difference value to the feedback prompt module.

[0035] If the virtual profile does not meet the preset planning indicators, a prompt message is output, and the process returns to the step of receiving input information to adjust the relevant parameters. If the virtual profile meets the preset planning indicators, a three-dimensional building model is generated based on the virtual profile.

[0036] Utilizing advanced 3D modeling algorithms, two-dimensional virtual cross-sectional information is transformed into a 3D architectural model. During the modeling process, factors such as the spatial structure, component details, and material textures of the courtyard house are fully considered to construct a highly realistic 3D model. For example, the beams, rafters, and brackets of traditional courtyard houses are accurately reproduced in form and detail through meticulous modeling operations; simultaneously, appropriate material textures, such as blue bricks and gray tiles, are assigned to the architectural model to showcase the traditional architectural style of Beijing courtyard houses.

[0037] In the 3D modeling process, the building facade can be either double-sided open, with an overhanging eave on the back, or with a closed eave on the back; the roof ridge can be either a plain ridge or a saddle ridge.

[0038] If the input information is modified, the above steps will be repeated to update the virtual profile and 3D building model, and to provide real-time feedback on changes in planning indicators.

[0039] On the other hand, such as Figure 2 As shown, this invention provides a design system for a dynamic adaptation design system of courtyard house planning indicators that implements parametric modeling of any of the above methods, comprising: The data input module is used to receive input information including building axis vector information, building facade form, roof ridge form, eaves height, and preset parameters; The parametric design module is connected to the data input module and generates a virtual building section based on the input information received by the data input module and the traditional courtyard house architectural style rules. The planning indicator matching module is connected to the parametric design module, loads preset planning indicators, and performs real-time comparison and analysis between the data corresponding to the virtual profile and the preset planning indicators. The feedback prompt module is connected to the planning indicator matching module and is used to output prompt information when the planning indicator matching module finds differences in comparison and analysis; The 3D modeling module, connected to the planning index matching module, is used to generate a 3D building model based on the virtual profile when the virtual profile conforms to the preset planning index.

[0040] like Figure 3 As shown, the data input module runs method S1, which includes: The building axis vector information input unit is used to receive building axis vector information input by the user. The building facade form selection unit is used to provide and receive users' choices of facade forms such as double-sided openness, rear eaves projection, and rear closed eaves. The ridge form selection unit is used to provide and receive the user's selection of the ridge form, such as the plain ridge or the saddle ridge. The eaves height input unit is used to provide and accept user input of key eaves height, and to define the input eaves height as the front eaves or the rear eaves. The preset parameter input unit is used to receive preset parameters input by the user. The preset parameters include at least the eaves depth, wall thickness, roof construction thickness, and platform height.
