[0002] During the design process of building curtain walls, designers need to complete the design work efficiently and accurately, and consider the impact of various environmental factors on the performance of the curtain wall. The field of building curtain wall design is undergoing profound technological changes, such as the introduction of BIM technology. BIM technology realizes the information management of the entire life cycle of the building through digital means, so as to improve the collaborative efficiency of each link of design, construction and operation.

[0003] At present, although the BIM curtain wall design systems on the market can assist designers in completing basic curtain wall design work, they usually lack the ability of intelligent parametric design and have obvious deficiencies in the functional integration of simulation, preview and collaborative design. As a result, there is a defect of low design efficiency in building curtain wall design, which urgently needs to be improved. Summary of the Invention

[0004] In order to improve the design efficiency of building curtain wall design, the present application provides a building curtain wall simulation design method, system, equipment and medium based on BIM.

[0005] In the first aspect, the invention objectives of this application are achieved by adopting the following technical solutions:

[0009] Optimizing the initial design and construction plan of the building curtain wall based on the collision detection result to obtain a curtain wall simulation design plan, and performing a construction simulation based on the curtain wall simulation design plan to obtain a construction simulation result;

[0010] Obtaining scheme revision parameters of a preset collaborative design platform based on the construction simulation results, and updating the curtain wall simulation design scheme based on the scheme revision parameters;

[0011] A curtain wall simulation design model is constructed based on the construction links, work content and corresponding workflow of the updated building curtain wall simulation design plan. The curtain wall simulation design model performs a visual construction scenario simulation on the design and construction process of the building curtain wall, obtains the simulation results and displays them on the preset collaborative design platform.

[0012] By adopting the above technical solution, during the designer's design process, the initial design and construction plan of the building curtain wall is first obtained, and the corresponding curtain wall component information and construction location node information are extracted, wherein the curtain wall component information includes the size, shape, and material property information of multiple types of curtain wall components, and the construction location node information is the construction layout position, construction construction node information, etc. of each curtain wall component. The main building BIM model is a main building model constructed using BIM technology to simulate the actual installation environment of the building curtain wall. Collision detection is performed through the curtain wall component information and construction location node information, and the rationality and accuracy of the initial design and construction plan are verified in an intelligent verification manner. The detection efficiency is high, and collision checks can be performed on design results of different disciplines, so that the optimized curtain wall simulation design plan is more in line with actual construction requirements. The curtain wall simulation design plan is constructed in an intelligent auxiliary design manner to present the construction design results in a more intuitive way, helping designers Designers and contractors can better understand and plan the construction process of building curtain walls, which is conducive to improving construction quality and safety. Designers can also input scheme correction parameters through the collaborative design platform based on real-time feedback of construction simulation results to update the curtain wall simulation design scheme, so as to control the construction quality. Then, a curtain wall simulation design model is constructed based on the construction links, work content and corresponding work processes of the updated building curtain wall simulation design scheme. The curtain wall simulation design model performs a visual construction scenario simulation on the design and construction process of the building curtain wall, so as to simulate the design results and construction process of the building curtain wall simulation design scheme. By previewing the design results in advance, designers can instantly view the design effect of the building curtain wall. The collaborative design platform is also in line with the actual design process, where there are multiple designers collaborating on the design. This application is conducive to improving the design efficiency of building curtain wall design through real-time preview and simulation, and the design operation is more convenient.

[0013] In a preferred embodiment of the present application, the collaborative design platform includes a BIM database of curtain wall component information and construction technical specification information; obtaining an initial design and construction plan for the building curtain wall, and obtaining corresponding curtain wall component information and construction location node information based on the initial design and construction plan, includes:

[0015] According to several of the construction processes, corresponding construction contents and curtain wall component information, all construction processes are associated with the construction technical specification information, and the construction position layout information and construction nodes of each component of the curtain wall component information are obtained based on the construction technical specification information; and the construction position node information is obtained based on the construction position layout information and construction nodes of each component.

[0016] By adopting the above technical solution, all construction processes of the entire building curtain wall during the construction process and the construction content corresponding to each construction process are obtained based on the initial design and construction plan. Based on the curtain wall components required for all construction processes and corresponding construction contents, the corresponding component identifications are associated one by one. The component identification is unique curtain wall component identification information. All curtain wall components designed during the construction process of the building curtain wall are associated with the corresponding component identifications to obtain curtain wall construction information; further, in order to verify the standardization and rationality of each construction process, this application obtains the construction position layout information of each component and the construction node of the curtain wall component based on the construction technical specification information, associates the construction position layout information of each curtain wall component with the corresponding component node, and maps it to the corresponding main building BIM model to obtain construction position node information. The construction position node information includes the installation coordinate information of each component in the main building BIM model, thereby facilitating the mold test of the curtain wall component and the main building BIM model, which is beneficial to improving the authenticity and restoration of the building curtain wall simulation design.

[0017] In a preferred example of the present application, in the pre-built main building BIM model, collision detection is performed based on the curtain wall component information and construction location node information to obtain collision detection results, including:

[0018] In the pre-built main building BIM model, the collision detection range and collision location information are obtained based on the construction location layout information of each component;

[0020] The collision detection range, collision position information, component outline parameters and size parameters are associated based on the component node, and collision detection is performed to obtain a collision detection result.

[0021] By adopting the above technical solution, in the BIM model of the main building, construction collision detection is carried out based on the initial construction design plan of the building curtain wall, and the overall collision detection range and collision position information of each component are obtained. By displaying the collision association of the detailed contour parameters and size parameters of the components, it is beneficial to improve the accuracy of collision detection. The collision detection results can be used to know the components with collision relationships and their locations, so as to provide more intuitive data support for the designer's design optimization.

[0022] In a preferred example of the present application, the collision detection range, collision position information, component outline parameters, and size parameters are associated with the component node, and collision detection is performed. After obtaining the collision detection result, the method includes:

[0023] Based on the collision position and the curtain wall components involved in the collision in the collision detection result, collision type information of each curtain wall component in a collision relationship is obtained; the collision type information includes hard collision, soft collision and gap collision; the curtain wall component is associated with a component identifier; and the collision type information is associated with a collision identifier;

[0024] According to the different collision marks and curtain wall components, corresponding collision component models are obtained and displayed separately;

[0025] In the pre-built main building BIM model, corresponding collision position information is displayed according to the collision position.

[0026] By adopting the above technical solution, different collision detection results are differentiated and associated and displayed. Since different types of collisions may occur during the actual construction of building curtain walls, such as hard collisions, soft collisions and gap collisions, in order to provide designers with more intuitive, clearly positioned and accurate collision detection results, the collision component model and collision position information are differentiated and displayed, so as to further improve the intelligence and automation of the building curtain wall simulation design system.

[0027] In a preferred embodiment of the present application, the method further includes:

[0028] In the curtain wall simulation design model, wind field load simulations of different scenarios are performed based on the acquired wind field load simulation data, and wind pressure intensity feedback diagrams of the different scenarios are generated accordingly. The wind pressure intensity feedback diagrams are obtained based on the wind pressure response data acquired when performing the wind field load simulation for each curtain wall component of the curtain wall component information;

[0029] In the curtain wall simulation design model, temperature excitation simulation is performed based on the acquired temperature and heat load simulation data, and corresponding heat load deformation evolution diagrams are produced for different time periods. The heat load evolution diagrams are obtained by fitting the component deformation trajectory data acquired when performing the temperature and heat load simulation data for each curtain wall component based on the curtain wall component information. The heat load deformation evolution diagrams dynamically render the component deformation trajectory data of each curtain wall component.

[0030] By adopting the above-mentioned technical solution, this application also provides multi-scenario wind field load simulation and time-series-based temperature excitation simulation functions to evaluate the performance of building curtain walls under different wind field conditions, providing a reference for designers to optimize the design of building curtain walls. It can also evaluate the changes of curtain wall components under different temperature conditions to analyze the damage to the components caused by thermal expansion and contraction of the curtain wall materials. The wind pressure intensity feedback diagram and the thermal load deformation evolution diagram can intuitively display the component characteristics and usage response of the building curtain wall under different working conditions in the actual installation environment.

[0031] In a preferred embodiment of the present application, the method further includes:

[0032] Associating the wind pressure response data of each curtain wall component of the curtain wall component information with the construction location node information to obtain component wind pressure intensity data and wind pressure intensity distribution position; associating different component wind pressure intensity data with corresponding component identifications;

[0033] Sending wind pressure strength data of different components to a preset judgment model to identify and obtain a threshold interval corresponding to the wind pressure strength data of the component; and judging whether the wind pressure strength data of the component is within the corresponding threshold interval;

[0034] When the wind pressure intensity data of a component is not within the corresponding threshold range, a wind pressure abnormality mark point is generated based on the component identifier and wind pressure intensity distribution position corresponding to the wind pressure intensity data of the component;

[0035] The wind pressure anomaly mark point is displayed in association with the wind pressure intensity feedback diagram.

[0036] By adopting the above technical solution, the wind pressure intensity data of different components are compared with the range of the corresponding threshold interval to determine whether the wind pressure intensity data of the components are stable. When the wind pressure intensity data of a component is not within the corresponding threshold interval, it indicates that the structural reliability and stability of the component in the current simulation design are insufficient, and optimization and design changes are required. At this time, the wind pressure abnormality mark points are displayed in association in the wind pressure intensity feedback diagram, so that designers can understand the structural response of curtain wall components under wind loads in different scenarios, and help designers evaluate the performance of building curtain walls.

The structural stress and strain analysis of the curtain wall structure of the building curtain wall is performed under different application scenarios through the dynamic wind pressure response data to analyze the deformation of the curtain wall components at different times, thereby understanding the vibration, deformation and stability performance of the curtain wall components under wind load.

[0099] S20: In the curtain wall simulation design model, a temperature excitation simulation is performed based on the acquired temperature and heat load simulation data, and corresponding heat load deformation evolution diagrams are produced for different time periods. The heat load evolution diagrams are obtained by fitting the component deformation trajectory data acquired when performing the temperature and heat load simulation data for each curtain wall component based on the curtain wall component information. The heat load deformation evolution diagrams dynamically render the component deformation trajectory data of each curtain wall component.

[0100] Specifically, thermal load analysis is performed using temperature heat load simulation data to determine the thermal load of curtain wall components. Thermal load includes the transfer and absorption of heat. The thermal attenuation and energy loss of curtain wall components during the heat transfer process are analyzed through thermal load analysis, and the thermal attenuation data of curtain wall components are predicted. Then, the thermal expansion and deformation evolution analysis of the component unit thermal load data is performed using the thermal attenuation data of the components to determine the dimensional change and shape deformation of the curtain wall components under temperature changes, so as to obtain the component deformation trajectory data. The component deformation trajectory data of each curtain wall component is dynamically rendered based on the thermal load deformation evolution diagram to intuitively display the component characteristics and usage response of the building curtain wall under different working conditions in the actual installation environment.

[0101] In one embodiment, if Figure 5 As shown in the figure, the BIM-based building curtain wall simulation design method also includes:

[0102] S101: Associating the wind pressure response data of each curtain wall component with the construction location node information of the curtain wall component information to obtain the component wind pressure intensity data and wind pressure intensity distribution position; and associating different component wind pressure intensity data with corresponding component identifiers.

[0103] In this embodiment, the wind pressure response data is associated with the construction location node information to facilitate subsequent analysis of the location of abnormal wind pressure response data.

[0104] S102: Sending different component wind pressure strength data to a preset judgment model, identifying and obtaining a threshold range corresponding to the component wind pressure strength data; and judging whether the component wind pressure strength data is within the corresponding threshold range.

[0105] Specifically, by comparing the wind pressure intensity data of different components with the range of the corresponding threshold interval, it is determined whether the wind pressure intensity data of the component is within the normal wind pressure response range.

[0106] S103: When the wind pressure intensity data of a certain component is not within the corresponding threshold range, a wind pressure anomaly mark point is generated based on the component identifier and wind pressure intensity distribution position corresponding to the component wind pressure intensity data.

[0107] S104: Displaying the wind pressure anomaly mark point in association with the wind pressure intensity feedback diagram.

[0108] Specifically, when the wind pressure intensity data of a component is not within the corresponding threshold range, it indicates that the structural reliability and stability of the component in the current simulated design are insufficient and optimization and design changes are required. At this time, the wind pressure abnormality mark points are displayed in the wind pressure intensity feedback diagram to help designers understand the structural response of curtain wall components under wind loads in different scenarios, thereby helping designers evaluate the performance of building curtain walls.
