Description

Technical Field

[0001] The invention belongs to the technical field of special-shaped door and window installation simulation, and in particular relates to a special-shaped door and window installation simulation method based on BIM technology. Background Art

[0002] The installation of special-shaped doors and windows is an important part of building construction, and its installation quality directly affects the beauty and usability of the building. The traditional installation method of special-shaped doors and windows mainly relies on the experience and skills of workers, lacks visual guidance and precise positioning, and is prone to problems such as door and window position deviation and size incompatibility, which affects the installation effect. At the same time, there are many types of special-shaped doors and windows with different shapes. Manual measurement and adjustment of installation positions are time-consuming, labor-intensive, and inefficient. How to achieve visual installation guidance and simulation of special-shaped doors and windows while ensuring installation accuracy and efficiency is a technical problem that needs to be solved urgently.

[0003] The emergence of BIM technology provides a new idea for solving this problem. By pre-arranging door and window openings in the BIM model and loading special-shaped door and window families into the model, the location and effect of door and window installation can be intuitively viewed. However, in actual operation, the installation of special-shaped doors and windows still faces many technical challenges: First, the shapes and sizes of special-shaped doors and windows vary. How to accurately create matching door and window openings in the BIM model requires a lot of manual adjustments and modifications; second, the location and angle of door and window installation need to be precisely matched with the wall, otherwise it will affect the opening and closing and sealing performance of the doors and windows, and the automatic alignment tool in the BIM software cannot meet the special requirements of the installation of special-shaped doors and windows; third, the BIM model can only statically display the final effect of door and window installation, and cannot simulate the various steps and details in the installation process, which is not conducive to guiding actual construction operations. Therefore, how to use BIM technology to achieve precise positioning, automatic correction and dynamic simulation of the installation of special-shaped doors and windows is a challenging technical problem. It is necessary to further develop a special special-shaped door and window installation module based on BIM software, and comprehensively use 3D modeling, parametric design, collision detection and other technical means to effectively solve various problems in the installation process of special-shaped doors and windows and improve the installation accuracy, efficiency and quality.

BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The drawings constituting a part of the present application are used to provide a further understanding of the present application. The illustrative embodiments and descriptions of the present application are used to explain the present application and do not constitute an improper limitation on the present application. In the drawings:

[0052] Figure 1 The present invention is a flowchart of a method for simulating installation of special-shaped doors and windows based on BIM technology. DETAILED DESCRIPTION

[0053] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0054] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0055] like Figure 1 As shown, this embodiment provides a method for simulating installation of special-shaped doors and windows based on BIM technology, including: obtaining a special-shaped door and window family file in BIM software, preprocessing the special-shaped door and window family file, and obtaining a wall structure model;

[0056] Based on the preset wall size and spatial position parameters, the contact surface between doors, windows and walls is calculated, and the opening size is automatically adjusted to ensure that the gap between doors, windows and walls meets the installation standards;

[0057] Setting the installation reference points of the doors and windows in the wall structure model, and determining the installation angles and positions of the doors and windows according to the reference point coordinates and the wall normal direction;

[0058] Perform collision detection on doors, windows and walls. If interference areas are found, the door and window positions are automatically adjusted or the opening size is modified until the collision risk is eliminated.

[0059] Extract the installation step information of doors and windows, generate dynamic installation simulation animation, and show the movement trajectory and adjustment process of doors and windows from the initial position to the final installation position;

[0060] According to the opening mode and structural characteristics of doors and windows, set the motion trajectory in different states, simulate the space occupancy in the process of opening and closing doors and windows, and determine the final motion trajectory plan of doors and windows;

[0061] Save the key parameters and adjustment records during the door and window installation process to the database, establish an installation parameter library, and determine the final door and window installation parameters;

[0062] Generate installation guidance documents based on the BIM model, dynamically simulate animations, and determine the final installation guidance plan.

[0063] Further, preprocessing the special-shaped door and window family file to obtain the wall structure model includes:

[0064] Obtain the special-shaped door and window family file in the BIM software, and parse the geometric parameter information in the special-shaped door and window family file;

[0065] Determine whether the shape of the door and window is regular according to the geometric parameter information; if the shape of the door and window is regular, automatically generate a corresponding opening model based on the geometric parameter information; if the shape of the door and window is irregular, extract edge feature information of the door and window;

[0066] Based on the edge feature information, a hole outline matching the wall structure is generated, and the matching of the generated hole model or hole outline and the wall structure is verified to obtain a wall structure model.

[0067] Specifically, after the opening model or outline is generated, it is necessary to verify the compatibility with the wall structure. This step ensures that the generated opening can be correctly matched with the wall in terms of size and position. For example, for a standard door with a height of 2.1 meters and a width of 0.9 meters, it is necessary to ensure that the wall has sufficient thickness and height at that location to accommodate the door opening. If the wall thickness is only 10 cm and the door frame requires an embedded depth of 15 cm, then the wall structure or the door installation method needs to be adjusted. When verifying the compatibility, structural safety also needs to be considered. For example, for a large French window, it is necessary to ensure that the wall can still bear sufficient load after the opening. This may involve structural calculations to ensure that the wall after the opening still meets the requirements of the building code. The final wall structure model not only contains accurate door and window openings, but also ensures the integrity and safety of the structure. This method can greatly improve the accuracy and efficiency of architectural design and reduce possible errors and rework during the construction phase.

[0068] Furthermore, determining the installation angle and position of doors and windows includes:

[0069] Obtain preset wall dimensions and spatial position parameters, and calculate the contact surface between doors, windows and walls based on geometric parameters;

[0070] Determine the gap requirements according to the installation standards, adjust the hole size to generate the hole model, if the door and window shape is regular, generate the hole model based on the geometric parameters, if the door and window shape is irregular, extract the edge features to generate the hole outline;

[0071] According to the preset wall size and space position parameters, obtain the installation reference point coordinates of doors and windows;

[0072] Determine the installation angle and position of doors and windows based on the reference point coordinates and the wall normal direction.

[0073] Furthermore, collision detection is performed on doors, windows and walls. If interference areas are found, the positions of doors and windows are automatically adjusted or the size of the openings is modified until the collision risk is eliminated.

[0074] S1. Obtain preset wall dimensions and door and window position parameters, and calculate contact surface geometry information between the door and window and the wall based on the geometry parameters;

[0075] S2. judging whether there is an interference area between the door and window and the wall according to the contact surface geometric information; if there is an interference area, optimizing the door and window positions by using the least square method and recalculating the interference area;

[0076] S3. If the interference area still exists after optimization, the hole size is adjusted based on the preset clearance requirement to generate a new hole model;

[0077] S4, predicting the deviation of doors and windows after installation through a neural network model, and adjusting installation parameters to optimize the final installation effect;

[0078] S5. Recalculate the contact surface geometry information between the doors and windows and the wall according to the optimized installation parameters to determine whether the collision risk has been eliminated. If the collision risk has been eliminated, determine the final installation plan; if not, repeat S1-S5 until the collision risk is completely eliminated.

[0079] Specifically, the new opening model needs to be verified for compatibility with the wall structure. This involves checking whether the adjusted opening affects the strength of the wall structure and whether it conflicts with the pipelines in the wall. For example, if the opening is too close to the load-bearing column, additional reinforcement measures may be required. Using a neural network model to predict installation deviations is an innovative approach. By inputting factors such as wall material, door and window weight, and installation process, the model can predict possible installation deviations. For example, if the prediction results show that the door frame may tilt 2 degrees to the right, it can be pre-adjusted during installation to ensure the accuracy of the final effect. The optimized installation parameters need to be re-verified. Assuming that the adjusted door and window position is 3 cm to the right and the height is reduced by 1 cm compared to the original plan, the contact surface needs to be recalculated to ensure that there is no new collision risk. This process may require multiple iterations until the risk is completely eliminated. For example, the first adjustment may solve the width problem, but height interference occurs, requiring a second round of optimization. This sophisticated calculation and optimization process ensures the accuracy and safety of door and window installation. It not only improves the quality of the building, but also reduces the cost of subsequent maintenance. Through digital and intelligent means, potential problems can be discovered and solved before construction, greatly improving engineering efficiency and finished product quality.

[0080] Furthermore, the final motion trajectory of doors and windows is determined by:

[0081] According to the opening mode parameters of doors and windows, obtain the preset opening angle range and movement direction;

[0082] Based on the opening angle range and movement direction, an initial mathematical model of the door and window movement trajectory is established;

[0083] According to the geometric position information of the components, the occupied area range of the door and window movement trajectory is calculated;

[0084] Based on the occupied area range, determine the interference risk level between the door and window movement trajectory and the components, and if the interference risk level exceeds a preset threshold, optimize the door and window movement trajectory;

[0085] According to the optimized motion trajectory model, the occupied area range and interference risk level are recalculated. If the interference risk level is lower than the preset threshold, the final motion trajectory plan of the doors and windows is determined.

[0086] Specifically, when calculating the occupied area range of the door and window movement trajectory, the dimensions of the door and window itself and the space swept during its movement need to be considered. For a hinged door, its occupied area can be approximated as a sector area with the hinge as the center and the door width as the radius. The occupied area of a sliding door is a rectangle, with the length equal to the door width plus the moving distance and the width equal to the door thickness. When judging the interference risk between the door and window movement trajectory and components, spatial partitioning technology can be used. The space is divided into grids, and each grid is marked whether it is occupied by the door and window or other components. If there is a situation where the same grid is occupied by multiple objects, it indicates an interference risk. The risk level can be evaluated according to factors such as the size and duration of the overlapping area. When the interference risk exceeds the preset threshold, the door and window movement trajectory needs to be optimized. The dynamic programming algorithm can be used to find the optimal solution. For example, for a hinged door, the trajectory can be optimized by adjusting the opening angle or changing the hinge position. The algorithm will evaluate each possible adjustment plan and select the plan that can minimize the interference risk to the greatest extent. The optimized movement trajectory model may result in a limited opening range or a change in the opening method of the door and window.

[0087] Furthermore, determining the final door and window installation parameters includes:

[0088] Based on the installation parameters and adjustment records obtained during the door and window installation process, extract key data and classify and store them;

[0089] According to the obtained installation parameters, establish a structured data model and store it in a preset database;

[0090] According to the door and window type, retrieve the installation data of similar doors and windows from the database to obtain reference data. If there are differences between the reference data and the current installation parameters, optimize the installation parameters;

[0091] According to the optimized installation parameters, update the parameter library in the database, and generate an installation plan based on the latest installation data obtained from the parameter library;

[0092] Determine the final door and window installation parameters according to the generated installation plan.

[0093] Furthermore, determining the final installation guidance plan includes:

[0094] Extract the geometric data and installation position information of the door and window from the BIM model to obtain the installation parameters of the door and window;

[0095] Generate an installation guidance document according to the extracted installation parameters;

[0096] According to the installation guidance document, produce a dynamic simulation animation to display the door and window installation process;

[0097] Associate the installation guidance document and the dynamic simulation animation to generate installation guidance materials;

[0098] According to the installation guidance materials, extract the key steps and precautions for door and window installation;

[0099] Optimize the key steps of installation and generate the optimal installation sequence;

[0100] According to the optimal installation sequence, the installation guidance file and the dynamic simulation animation are updated to determine the final installation guidance plan.

[0101] Specifically, the installation guide file can be associated with the animation by using augmented reality (AR) technology. When the construction personnel scan the installation location through the mobile device, they can see the text guidance and 3D animation superimposed on the actual environment at the same time, which greatly improves the installation efficiency and accuracy. When the clustering algorithm optimizes the installation steps, it can be based on the historical installation data of different door and window types. The final installation guidance plan should be a comprehensive document containing text instructions, diagrams, animation links, etc. For example, for a specific window installation, the plan may be presented as follows: "Step 1: Clean the opening (2 minutes); Step 2: Install the waterproof layer (5 minutes, pay attention to overlap with the wall by 150mm); Step 3: Position the window frame (3 minutes, use a laser level)", each step is equipped with a corresponding AR marker, and a detailed 3D demonstration can be seen after scanning. This systematic and digital door and window installation method can not only improve construction efficiency, but also ensure the consistency of installation quality. By continuously collecting and analyzing installation data, the system can continuously optimize installation parameters and processes, and promote the entire industry to develop in a more efficient and accurate direction.

[0102] Furthermore, a computer-readable storage medium is provided, wherein the computer-readable storage medium stores a special-shaped door and window installation simulation program based on BIM technology, and when the special-shaped door and window installation simulation program based on BIM technology is executed by a processor, the steps of the special-shaped door and window installation simulation method based on BIM technology are implemented.

[0103] The present invention discloses a method for simulating the installation of special-shaped doors and windows based on BIM technology, which can automatically generate a matching wall opening model according to the special-shaped door and window family file, and ensure adaptation to irregular shapes by extracting the edge features of the doors and windows. The present invention automatically calculates the contact surface between the doors and windows and the wall, adjusts the opening size to meet the installation standards, and uses preset reference points to accurately locate the installation position of the doors and windows. Through collision detection and automatic adjustment, the present invention eliminates the risk of interference during the installation process. In addition, the present invention can also generate dynamic installation simulation animations to display the installation trajectory and opening and closing process of doors and windows, and save key parameters to a database for reference. Finally, the present invention generates a detailed installation guidance document to provide precise guidance for on-site operations, thereby improving the efficiency and accuracy of door and window installation, reducing human errors, and realizing an intelligent and standardized installation process.
