Description

Technical Field

[0001] The present invention relates to the technical field of building module arrangement, and in particular to a building module arrangement method and device based on building plane layout. Background Art

[0002] Modular construction, as an innovative architectural concept, has been rapidly promoted and applied worldwide in recent years. Its core concept is to break down a building into several standardized modules, enabling rapid construction through prefabrication and assembly of these modules.

[0003] Despite its numerous advantages, modular construction still faces challenges in practical application. For example, when determining the module division scheme based on the building plan, traditional methods rely on the designer's experience to manually divide the modules. However, it is difficult for humans to efficiently and accurately complete the division and filling of modules, which to some extent affects the design efficiency and quality of modular buildings. Many building plans are complex and diverse. When arranging modules, it is necessary to minimize the number of modules while meeting the building's usage requirements. Moreover, the size of each module must also take into account the requirements of production, transportation, lifting, and stress. These multiple factors complicate the modular layout of building plans, limiting its wider application.

[0004] With the rapid development of computer technology, digitalization and intelligentization have gradually become important development directions in the field of architectural design. Computer technology has made the design process more efficient and precise. Using computer-aided design software, designers can more intuitively design modular building solutions, including 3D modeling and simulation analysis, to better predict and optimize building performance. The application of computer technology also makes it possible to automatically generate modular division plans based on building floor plans, greatly improving design efficiency.

[0005] Currently, there are few intelligent design methods for modular building module layouts. Combining a genetic algorithm with a full-stress design method, a modular steel structure building unit size optimization and intelligent structural design method is proposed based on a given unit topology. Although this method takes the building layout into account, the unit type is a given and immutable unit type. Based on this unit type, the dimensions of each module are optimized, making it suitable for optimizing a given building plan. An intelligent generative method based on a genetic algorithm and a planar tiling algorithm is proposed to solve the optimal plan layout for modular steel structures. However, this method arranges rectangular modules of a given module size within a feasible domain without considering the building plan layout. Both of the above methods only consider rectangular modules and do not consider L-shaped modules.

[0006] In the prior art, there is a lack of an efficient and accurate building module arrangement method based on the building plan layout and applicable to two modules. Summary of the Invention

[0038] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0039] The embodiment of the present invention provides a method for arranging building modules based on a building plan layout. The method can be implemented by a building module arranging device, which can be a terminal or a server. Figure 1 The flowchart of the method for arranging building modules based on the building plan layout is shown. The processing flow of the method may include the following steps:

[0040] S1. Obtain building plan drawing information and building module information.

[0041] The building module information includes building module size and building module type; the building module type includes rectangular building module and L-shaped building module.

[0042] In a feasible implementation, the module shapes are rectangular and L-shaped. During the arrangement process, the rectangular modules can be arranged horizontally or vertically, and the L-shaped modules can be rotated 0°, 90°, 180°, and 270°.

[0043] S2. According to the building plan drawing information, the preset LISP code is used to traverse the wall objects and extract the wall coordinates to obtain the starting point coordinates and endpoint coordinates of the wall; the central axis coordinates are extracted according to the starting point coordinates and endpoint coordinates to obtain the central axis position information.

[0044] In one feasible implementation, the present invention uses List Processing Language (LISP) to extract wall axis data from architectural plan drawings. LISP is suitable for processing list and tree-structured data. Taking AutoCAD as an example, LISP has been widely used in AutoCAD secondary development, enabling various custom functions and extending the functionality of CAD software. LISP allows developers to directly access and manipulate objects in CAD drawings. By calling the API (Application Programming Interface) provided by AutoCAD, LISP code can read object attributes, query geometric characteristics, perform mathematical calculations, and more.

[0045] When extracting the center axis of a wall, the LISP code can traverse all wall objects in the drawing, identify objects with center axis attributes, and extract coordinate information. Extract the starting point X coordinate, starting point Y coordinate, end point X coordinate, and end point Y coordinate of all wall axis segments in the building plan into a CSV file, use the pandas library function in Python to read the data, and then use the matplotlib library to draw the read line segment information. The extraction result of the center axis is as follows: Figure 2 shown.

[0046] S3. Based on the architectural plan drawing information, the outer contour line is extracted according to the starting point coordinates, the end point coordinates and the center axis position information to obtain the outer contour line position information.

[0047] Optionally, based on the architectural plan drawing information, outer contour line extraction is performed according to the starting point coordinates, the end point coordinates and the center axis position information to obtain the outer contour line position information, including:

[0048] Determine the starting point coordinates and endpoint coordinates as LineString objects;

[0049] Based on the LineString object, extract the point with the smallest horizontal coordinate value to obtain the filtered point set;

[0050] In the filtered point set, extract the point with the smallest vertical coordinate value and obtain the lower left corner point as the starting position;

[0051] Based on the architectural plan drawing information and the central axis position information, starting from the lower left corner point, according to the LineString object, the outer contour line segments are collected in a clockwise direction to obtain the outer contour line position information.

[0052] In one feasible implementation, the present invention processes architectural plan data read from a CSV file to facilitate subsequent code writing. Shapely is a Python programming library that uses a Cartesian coordinate system for geometric shape manipulation and analysis. It can implement and manipulate basic geometric objects such as points, lines, and polygons. The starting point X coordinate, starting point Y coordinate, endpoint X coordinate, and endpoint Y coordinate of all line segments are extracted and defined as LineString objects. To obtain the outer contour line data, it is necessary to traverse each central axis and collect the line segments that are the outer contour lines.

[0053] Optionally, based on the building plan drawing information and the central axis position information, starting from the lower left corner point, outer contour line segments are collected in a clockwise direction according to the LineString object to obtain outer contour line position information, including:

[0054] Determine the lower left corner point as point p1;

[0055] Based on the building plan drawing information and the central axis position information, obtain the first line segment position information corresponding to point p1; based on the first line segment position information and point p1, obtain another point p2 of the line segment;

[0056] Based on the building plan drawing information and the central axis position information, find the second line segment position information set with p2 as the endpoint;

[0057] Based on the first line segment position information, a calculation is performed according to the second line segment position information set to obtain a line segment angle set;

[0058] Based on the second line segment position information set, select the line segment corresponding to the minimum value in the line segment angle set as the second line segment position information; obtain another point p3 of the line segment based on the second line segment position information and point p2;

[0059] Determine point p2 as point p1; determine point p3 as point p2; repeat the above steps until point p3 is the lower left corner point, and collect the second line segment position information obtained in each round of calculation to obtain the outer contour line position information.

[0060] In one feasible implementation, this step begins with a line segment at the lower left corner of the plan view and proceeds clockwise to collect the outermost line segments. The set of points with the smallest X coordinate is extracted. Within this set, the point with the smallest Y coordinate is extracted. This point is called the lower left corner point. This point must be the endpoint of a line segment forming the outer contour. Next, one or more line segments with one endpoint being the lower left corner point are extracted. Among these line segments, the point with the smallest Y coordinate is found at the other endpoint. The line segment formed by this point and the lower left corner point is the starting line segment.

[0061] The lower left corner of the starting line segment is set as point p1, and the other point is set as p2. Find other line segments with point p2 as the endpoint, and set the other endpoint as point p3. Calculate the clockwise angle between the vector from p2 to p3 and the vector from p2 to p1, and select the point p3 that represents the smallest angle. The diagram is as follows Figure 3 As shown. Collect line segments with endpoints p2 and p3, assign P2 to p1, assign p3 to p2, and repeat until returning to the starting line segment. The collection of all collected line segments is the outer contour line data, as shown Figure 4 shown.

[0062] S4. Based on the architectural plan drawing information, the inner walls in the architectural layout are extended toward both ends according to the starting point coordinates and the end point coordinates to obtain wall grid lines.

[0063] In one feasible implementation, considering the building layout, the corner points of the modules should be arranged at the intersection of a wall or multiple walls, rather than at any arbitrary location in the room. Here, the inner walls of the module arrangement area are extended to both ends. When all the horizontal and vertical walls are extended, the wall grid lines are obtained, and all the wall grid lines are divided from each other, such as Figure 5 shown.

[0064] S5. Arrange modules based on the wall grid lines, outer contour line position information, and building module information to obtain a building module arrangement plan.

[0065] Optionally, based on the wall grid lines, modules are arranged according to the outer contour position information and the building module information to obtain a building module arrangement plan, including:

[0066] Based on the position information of the outer contour line, the upper left corner of the outer contour line is used as the starting point;

[0067] According to the building module information, obtain the building module information of this round;

[0068] Based on the starting point, wall grid lines, and the information of the building modules arranged in this round, the building modules are arranged along the outer contour lines according to the arrangement principles to obtain the arrangement results;

[0069] Save the information of the building modules arranged in this round to the stack M information storage module;

[0070] Calculate the new outer contour position information based on the current round of building module arrangement information and the outer contour position information; save the new outer contour position information to the stack W information storage module;

[0071] When the outer contour line is full of modules, the building module arrangement plan is output according to the stack M information storage module and the stack W information storage module.

[0072] In one feasible implementation, a stack is a linear data structure that manages data using the "first in, last out" principle. The process of adding an element is called "pushing," and the process of removing an element is called "popping." In this invention, two stacks are established. The first stack, referred to as "stack M," stores module types and layout information. The second stack, referred to as "stack W," stores updated outline information after module layout.

[0073] The stack does not allow direct access to the bottom element, but can only reach the bottom by removing the elements at the top one by one. The module arrangement scheme adopted in the present invention is to arrange the modules from the upper left of the outer contour line. Every time a module is successfully arranged, the module information is put into the stack M, and the outer contour lines of the remaining unarranged module areas are extracted, that is, the information of the outer contour lines of the updated ones is put into the stack W, and circulates successively. If all modules in the module data set cannot be arranged in a certain position, the information of the top layers of stack M and stack W is released so that the modules are arranged backward from the progress of the previous step, and the effect of backtracking is achieved, until the whole outer contour line is covered with modules. By stacking and popping functions, all module arrangement schemes under this given module data set can be generated at last.

[0074] Among them, the layout principles include the first principle and the second principle; the first principle is that the building module is within the outer contour line; the second principle is that the corner points of the building module coincide with the grid intersection points of the wall grid lines.

[0075] In a feasible implementation, to determine whether a module can be arranged in a certain position, it is necessary to satisfy the following conditions: all corner points of the module must be at the grid intersections of the wall grid lines, and all parts of the module must be within the outer contour line.

[0076] In a feasible implementation, the present invention generates 25 schemes based on actual building data. Among them, the modular building layout scheme should minimize the number of module types and modules. There is no strong correlation between the two. The specific selection can be based on the actual situation. The selected schemes are as follows: Figure 6 、 Figure 7 As shown in the figure, Scheme 16 uses 14 modules and 7 types of modules, while Scheme 24 uses 16 modules and 6 types of modules. Through the above technical solutions and methods, the building layout is fully considered, and the flexible use of two types of modules can be achieved. This allows for efficient and accurate processing of the building plan, generating a modular building solution that meets the design requirements.

[0077] This invention proposes a building module layout method based on building plan layout. By extracting axis data from the building plan and taking the building plan layout into account, this method efficiently and accurately processes the building plan, given a given module dataset, to generate a modular building solution that meets design requirements. By storing module and outline information in a stack, the stack push and pop operations are used to retrospectively correct errors in the module layout process. This invention provides an efficient and accurate building module layout method based on building plan layout and applicable to both types of modules.
