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] As an innovative architectural concept, modular construction has been rapidly promoted and applied around the world in recent years. Its core is to split the building into several standardized modules and realize the rapid construction of the building through the prefabrication and assembly of modules.

[0003] Although modular buildings have many advantages, they still face some challenges in practical applications. For example, when determining the module division scheme based on the building plan, traditional methods basically rely on the designer's experience to manually divide the modules. It is difficult to divide and fill the modules efficiently and accurately, which affects the design efficiency and quality of modular buildings to a certain extent. Many building plans are complex and diverse. When arranging modules, it is necessary to minimize the types of modules while meeting the needs of building use. In addition, the size of each module also needs to consider the requirements of production, transportation, hoisting, force and other links. These multiple factors make the module layout of the building plan complicated, limiting its application in a wider range.

[0004] With the rapid development of computer technology, digitalization and intelligence have gradually become important development directions in the field of architectural design. Computer technology makes the design process more efficient and accurate. Designers can design modular building solutions more intuitively by using computer-aided design software, including three-dimensional modeling, simulation analysis, etc., so as to better predict and optimize the performance of buildings. The application of computer technology also makes it possible to automatically generate module division schemes based on building floor plans, greatly improving the efficiency of design.

[0005] At present, there are few intelligent design methods for modular building module arrangement. Combining genetic algorithm and full stress design method, a modular steel structure building apartment size optimization and intelligent structural design method is proposed given the topological relationship of a given apartment. Although this method takes into account the building layout, the apartment type is given and immutable. On the basis of the apartment type, the size of each module is optimized, which is suitable for optimizing a given building plan. An intelligent generative method based on genetic algorithm and plane paving algorithm is used to solve the optimal plane layout of modular steel structure buildings, but this method arranges rectangular modules of given module size in a feasible domain without considering the building plan layout. Both of the above methods only consider the module shape as a rectangle, 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

[0007] In order to solve the technical problems of the prior art that the building plan layout is not considered and the two types of building modules are not compatible, the embodiment of the present invention provides a building module arrangement method and device based on the building plan layout.

[0038] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, 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, which can be implemented by a building module arrangement 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 in the figure. 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 architectural plan drawing information, the wall object is traversed through the preset LISP code, and the wall coordinates are extracted to obtain the starting point coordinates and the endpoint coordinates of the wall; the central axis coordinates are extracted according to the starting point coordinates and the endpoint coordinates to obtain the central axis position information.

[0044] In a feasible implementation, the present invention uses List Processing Language (LISP) to extract the axis data of the wall from the architectural plan drawing. LISP is suitable for processing list and tree structured data. Taking Auto CAD as an example, LISP language has been widely used in the secondary development of Auto CAD. Through LISP language, various custom functions and extended functions of CAD software can be realized. LISP language allows developers to directly access and operate objects in CAD drawings. By calling the API (application programming interface) provided by Auto CAD, LISP code can read the attributes of the object, query geometric characteristics, perform mathematical calculations, etc.

[0045] When extracting the central axis of the wall, the LISP code can traverse all wall objects in the drawing, identify objects with central axis attributes, and extract coordinate information. Extract the starting point X coordinate, starting point Y coordinate, endpoint X coordinate, and endpoint 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 central 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 the endpoint coordinates as LineString objects;

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

[0050] In the screening point set, extract the point with the smallest vertical coordinate value to 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 a feasible implementation, the present invention processes the architectural plan drawing data read from the CSV file to facilitate the subsequent code writing. Shapely is a Python programming library that uses the Cartesian coordinate system to perform geometric shape operations and analysis. It can implement and operate some basic geometric objects such as points (Point), lines (LineSring) and polygons (Polygon). Extract the starting point X coordinate, starting point Y coordinate, endpoint X coordinate, and endpoint Y coordinate of all line segments and define them as LineString objects. In order 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 architectural 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 architectural plan drawing information and the central axis position information, obtain the first line segment position information corresponding to the point p1; and obtain another point p2 of the line segment according to the first line segment position information and the point p1;

[0056] Based on the architectural plan drawing information and the central axis position information, find a 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 according to the second line segment position information and the 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 a feasible implementation, in this step, starting from a line segment at the lower left corner of the plane, the outermost line segments are collected in a clockwise direction. The point set with the smallest X coordinate is extracted, and the point with the smallest Y coordinate in the point set is called the lower left corner point. This point must be the endpoint of a line segment constituting the outer contour line. Then, one or more line segments with one endpoint being the lower left corner point are extracted, and the point with the smallest Y coordinate among the other endpoints of these line segments is found. 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 represented by the smallest angle. The schematic 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 you return 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, according to the starting point coordinates and the end point coordinates, the inner walls in the architectural layout are extended to both ends to obtain wall grid lines.

[0063] In a feasible implementation, considering the building layout, the positions of the corner points of the modules should be arranged at the intersection of a wall or multiple walls, rather than at any position 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 grid lines of the wall 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, the outer contour line position information and the 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 line position information and the building module information to obtain a building module arrangement scheme, including:

[0066] Based on the position information of the outer contour line, the upper left corner point 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 of arrangement;

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

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

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

[0071] When the outer contour 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 a 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 into the stack" and the process of removing an element is called "popping out of the stack." Two stacks are established in the present invention. The first stack is used to store the type and arrangement position information of the module, and this stack is called "stack M." The second stack is used to store the information of the outer contour line updated after the module is arranged, and this stack is called "stack W."

[0073] The stack does not allow direct access to the bottom elements, 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 updated is put into the stack W, and circulated in sequence. If all modules in the module data set cannot be arranged in a certain position, then the information of the top layer of stack M and stack W is pushed out, and the modules are arranged backward from the progress of the previous step, and the effect of backtracking is achieved, until the entire outer contour line is full of modules. Through the push and pop functions, all the module arrangement schemes under this given module data set can be generated at last.

[0074] Among them, the arrangement 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 point of the building module coincides with the grid intersection point of the wall grid line.

[0075] In a feasible implementation manner, to determine whether a module can be arranged in a certain position, it is necessary to satisfy that 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, and 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. Among them, Scheme 16 uses 14 modules and 7 types of modules; Scheme 24 uses 16 modules and 6 types of modules. Through the above technical solutions and methods, the building layout is fully considered, and two shapes of modules can be flexibly arranged to achieve efficient and accurate processing of the building plan, and generate a modular building plan that meets the design requirements.

[0077] The present invention proposes a method for arranging building modules based on the building plan layout. By extracting the axis data of the building plan and considering the building plan layout, the building plan is efficiently and accurately processed under the premise of a given module data set, and a modular building plan that meets the design requirements is generated. By storing the module and contour line information in a stack, the stack is pushed and popped to backtrack and correct the module arrangement process. The present invention is an efficient and accurate building module arrangement method based on the building plan layout and applicable to two modules.
