Description

Technical Field

[0001] This invention relates to the field of architectural design, and more particularly to a method, apparatus, equipment and storage medium for residential water supply layout. Background Technology

[0002] The layout of residential water supply pipes is one of the most time-consuming design processes in water supply and drainage design. It is also a very detailed process. To save time, designers often use a simplified two-dimensional representation, which does not accurately reflect the actual installation effect. This results in a lot of time being spent communicating during the construction process. Sometimes, errors are only discovered after construction is completed, requiring demolition and reconstruction, which is an unnecessary expense for real estate developers.

[0003] Currently, there are two technical solutions: one is AutoCAD-aided design software developed by Autodesk. The water supply pipes and water-using equipment drawn by this software exist in two-dimensional form, which cannot accurately express the actual height of the pipes, the connection points of the water-using equipment, and other information. Due to the lack of information, it is impossible to use CAD to better develop automated design functions. At present, designers can only complete the design work manually, which takes a long time and greatly affects the development cycle.

[0004] Secondly, there is Autodesk's Revit design software. This software creates water supply pipes and water-using equipment in three dimensions, and can include information such as pipe height and water-using equipment connection points. Some companies have tried to use this information for automated design, but it is limited to the connection of a single water-using equipment and a single water supply pipe. It cannot consider the water supply pipe connection of all water-using equipment globally, so the degree of automation is not high. It is only slightly more efficient than the CAD design mode. Most of the work is still done manually, which is time-consuming and also greatly affects the development cycle. Summary of the Invention

Detailed Implementation

[0024] This application provides a method, apparatus, equipment, and storage medium for residential water supply layout. The method involves acquiring a 3D model of the residential building to be arranged and the water supply parameters of each room within the model; calculating the runnable space for water supply pipes in the 3D model based on the water supply parameters; dividing the runnable space into a grid using a preset visualization algorithm to obtain the grid lines of the 3D model; using water-using devices in the 3D model as starting points and water meters as ending points, performing path planning within the grid lines to obtain the corresponding optimal path, and using the optimal path as the residential water supply line in the 3D model.

[0025] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" or "having" and any variations thereof are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0026] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 The first embodiment of the residential water supply layout method in this invention includes: 101. Obtain the 3D model of the residence to be arranged and the water supply parameters of each room in the 3D model; It is understood that the executing entity of this invention can be a residential water supply system, a terminal, or a server; no specific limitation is made here. This embodiment of the invention will be described using a server as an example.

[0027] In this embodiment, before arranging the water supply, the user needs to use Revit software to create a 3D model of the residence to be arranged. The 3D model of the residence to be arranged consists of 3D models of rooms, walls, beams, slabs, columns, water meters, and water-using equipment. The rooms are labeled with names so that the subsequent algorithm can directly obtain the parameter information of the required rooms.

[0028] In this embodiment, after generating a 3D model of the residence to be arranged, the user needs to input the water supply parameters of each room in the 3D model according to actual needs. The water supply parameters mainly define the water supply characteristics of different rooms, which affect the subsequent algorithm's arrangement of water supply pipes in that room. The water supply parameters include whether water supply pipes are allowed to pass through, whether the water supply pipes are arranged on the ceiling or subfloor of the room, etc. In addition, the water supply parameters can also be factors in other rooms that affect the arrangement of water supply pipes, which are not limited in this invention.

[0029] 102. Calculate the space where the water supply pipe can run in the three-dimensional model based on the water supply parameters; In this embodiment, the characteristics of different rooms are determined based on the water supply parameters of different rooms, and spatial extraction is performed based on the characteristics of each room. The data of the horizontal space and the vertical space in each room are extracted, and the horizontal space and vertical space of all rooms are merged to obtain the water supply pipe travel space of the three-dimensional model. The water supply pipe travel space is used to characterize the spatial area in the three-dimensional model where the water supply pipe can be arranged.

[0030] 103. The space in which the water supply pipe can run is divided into grids according to the preset visual algorithm to obtain the grid lines of the three-dimensional model; In this embodiment, each room is marked as waterproof or not waterproof based on the water supply parameters. Whether a room is waterproof or not will affect the grid line division parameters of that room. If the room is waterproof, grid lines can be generated at any position in the room. If the room is not waterproof, the grid lines must be arranged along the wall.

[0031] In this embodiment, the three-dimensional walkable space is transformed into a planar region. Based on whether the room is waterproof, a grid is constructed within the region. The grid must ensure that there are one or more compliant movement paths between each starting point and the ending point in the space. The improved VisibilityGraph algorithm is mainly used in the grid division process.

[0032] In this embodiment, after dividing the grid lines, it is necessary to define the obstacles in the room, distinguish which grid lines cannot be crossed and which can only be crossed perpendicularly. It is necessary to analyze the crossing relationship between water supply pipes and each type of obstacle in actual engineering. The obstacles include beams, slabs, columns, water meters and water-using equipment that make up the house to be arranged. At the same time, in order to meet the aesthetic requirements of water supply pipe layout, it is necessary to convert grid lines that are not orthogonal and match the relationship between the grid lines and the direction of the room walls. Find the room wall where the grid line is closest and match the grid line with the same perpendicular direction of the successfully matched relationship to ensure that the grid lines are divided along the wall.

[0033] 104. Using the water-using equipment in the 3D model as the starting point and the water meter equipment in the 3D model as the ending point, perform path planning on the grid lines to obtain the corresponding optimal path, and use the optimal path as the residential water supply line in the 3D model.

[0034] In this embodiment, the water supply pipe is used to connect the water-using equipment and the water meter. The layout of the residential water supply line is determined by calculating the optimal path between the two. The optimal path refers to the optimal distance between the two, which is affected by various factors, including the number of bends, the straight-line distance, the number of times the pipe passes through walls, and the number of times it intersects with other water supply pipes. The proportional relationship between different factors can be displayed in the operation interface. When the optimal path does not meet the user's needs, the weight ratio can be reset, and the algorithm will recalculate the optimal path and recommend it to the user. This operation continues until the generated path meets the user's needs. After the path is determined, it can be converted into a three-dimensional pipeline.

[0035] In this embodiment, the optimal path between two points is calculated using an improved Dijkstra algorithm. The algorithm automatically takes each water-using device in the 3D model as the starting point and the water meter as the ending point. The grid lines are divided as the movement route from the starting point to the ending point. By traversing the path algorithm, multiple connecting routes are obtained. The route records the number of turns, line segment length, number of walls passed through, and number of intersections. The values ​​are multiplied by the corresponding weight ratio and converted into distance length. Finally, the shortest path is selected as the optimal path.

[0036] In this embodiment, a 3D model of the residence to be arranged and the water supply parameters of each room in the 3D model are obtained. The feasible space for water supply pipes in the 3D model is calculated based on the water supply parameters. The feasible space for water supply pipes is then divided into grids according to a preset visualization algorithm, resulting in grid lines for the 3D model. Using water-using devices in the 3D model as the starting point and water meters as the ending point, path planning is performed within the grid lines to obtain the corresponding optimal path, which is then used as the residential water supply line in the 3D model. This method leverages the information inherent in 3D models and, combined with engineering experience, extracts a set of universal algorithms to ensure that the generated results can reproduce the actual water supply pipe layout scene to the greatest extent possible. Simultaneously, it solves the problem of slow rendering speed in existing technologies, enabling the generation of water supply pipes for the entire building in a short time.

[0037] Please see Figure 2 The second embodiment of the residential water supply layout method in this invention includes: 201. Obtain the 3D model of the residence to be arranged and the water supply parameters of each room in the 3D model; 202. Extract the horizontal and vertical spaces corresponding to each room in the 3D model based on the water supply parameters; 203. Merge the horizontal and vertical spaces of all rooms to obtain the space where the water supply pipes can run in the three-dimensional model; 204. Convert the space where the water supply pipe can run into multiple planar regions; 205. Identify obstacles in the 3D model and obtain the outline of the obstacles in the planar region, wherein the outline includes the outline endpoints and the outline lines on which the outline endpoints are located; In this embodiment, a contour refers to a closed, non-self-intersecting polygon formed by a series of continuous points. A planar region refers to a planar space containing 0 or 1 outer contours and n (n>=0) inner contours. The outer contours and inner contours do not intersect, and the space enclosed by the inner contours is a subset of the space enclosed by the outer contours. Such a planar region can abstractly describe any inner and outer planar space in a 3D model.

[0038] In this embodiment, each contour map contains multiple edges, i.e. contour lines, and each contour line has multiple points, two of which are contour endpoints. The contour endpoints on the outer and inner contours of the planar region are extracted using the Revit API. In addition, when the contour contains curves, the curves are converted into polylines with a certain precision before the contour endpoints are extracted.

[0039] 206. Emit rays from all contour endpoints along the contour lines they belong to, wherein the rays stop when they collide with other contour lines; In this embodiment, each contour endpoint in the contour map is rayed outward along a direction parallel to its line, and collision events are detected. The process stops when a ray collides with the contour line of another contour. By traversing each contour line and the contour endpoints on the contour line, all rays are treated as grid lines.

[0040] In this embodiment, the visibility graph of the 3D image can be calculated first based on the ordinary Visibility Graph algorithm. After obtaining the visibility graph, grid lines can be obtained by replacing all the diagonal lines in the visibility graph with two corresponding mutually perpendicular lines.

[0041] 207. Based on the water supply parameters, determine whether the room where the rays emitted from each contour point are located is waterproof; 208. If not, then remove any non-waterproof rays from the room. 209. Generate the mesh lines of the 3D model based on the removed rays; In this embodiment, after generating the mesh lines of the three-dimensional model based on the removed rays, the method further includes determining the direction of all mesh lines in the three-dimensional model; determining whether there are any mesh lines in the three-dimensional model whose direction is not orthogonal; if so, converting the non-orthogonal mesh lines into mesh lines with two orthogonal directions that are perpendicular to each other.

[0042] Specifically, since the direction of the outline may not be orthogonal, and in order to meet the aesthetic requirements of the water supply pipe layout, it is necessary to ensure that the grid lines are orthogonal. Therefore, after obtaining the initial grid lines, it is necessary to replace the diagonal lines in the grid lines that are not orthogonal with two corresponding mutually perpendicular lines to obtain the grid lines.

[0043] 210. Using the water-using equipment in the 3D model as the starting point and the water meter equipment in the 3D model as the ending point, perform path planning on the grid lines to obtain the corresponding optimal path, and use the optimal path as the residential water supply line in the 3D model.

[0044] This embodiment, based on the previous embodiment, details the process of dividing the walkable space of the water supply pipe into a grid according to a preset visual algorithm to obtain the grid lines of the 3D model. This involves converting the walkable space of the water supply pipe into multiple planar regions; identifying obstacles in the 3D model and obtaining the contour maps of the obstacles within the planar regions, wherein the contour maps include contour endpoints and the contour lines containing the contour endpoints; and dividing the walkable space of the water supply pipe into a grid based on the contour endpoints of all obstacles and the contour endpoints themselves to obtain the grid lines of the 3D model. This method differs from purely manual 2D design in CAD and from the single-point generation functions for water supply pipes currently available on the market. This method combines practical engineering experience and analysis of diverse residential floor plans, extracting a universal and flexible algorithm. Combined with rapid computing power, this allows designers to generate a water supply pipe layout model for the entire building in a short time, significantly shortening the design cycle and more intuitively expressing design intent.

[0045] Please see Figure 3 The third embodiment of the residential water supply layout method in this invention includes: 301. Obtain the 3D model of the residence to be arranged and the water supply parameters of each room in the 3D model; 302. Calculate the space where the water supply pipe can run in the three-dimensional model based on the water supply parameters; 303. The space in which the water supply pipe can run is divided into grids according to the preset visual algorithm to obtain the grid lines of the three-dimensional model; 304. Extract all nodes from the grid points; 305. Using the nodes corresponding to the water-using equipment in the 3D model as the starting point and the nodes corresponding to the water meter equipment in the 3D model as the ending point, generate multiple connected paths. 306. Obtain the weight ratio parameters input by the user, wherein the weight ratio parameters include the weight ratio of the number of turns, the weight ratio of the distance length, the weight ratio of the number of walls passed through, and the weight ratio of the number of intersections. 307. Determine the number of turns, line segment lengths, number of wall penetrations, and number of intersections for each connecting path; In this embodiment, the number of turns refers to the number of times the connecting path changes direction, the line segment length refers to the length of the connecting path on the grid line, the number of wall penetrations refers to the number of times the connecting path crosses a wall, and the number of intersections refers to the number of times the connecting path intersects with other water supply pipes.

[0046] 308. Calculate the distance of each connecting path based on the number of turns, line segment length, number of wall penetrations, number of intersections, and weight ratio parameters, and take the connecting path with the shortest distance as the corresponding optimal path. 309. Use the optimal path as the residential water supply line in the three-dimensional model.

[0047] In this embodiment, an improved version of Dijkstra's algorithm is used. Dijkstra's algorithm is stable and adaptable to changes in network topology, making it a classic algorithm for path planning. The idea behind Dijkstra's algorithm is as follows: Let G = (V, E) be a weighted directed graph. Divide the set of vertices V into two groups. The first group is the set of vertices for which the shortest path has been found (denoted by S; initially, S contains only one source vertex. Each time a shortest path is found, it is added to set S until all vertices are added to S, at which point the algorithm terminates). The second group is the set of vertices for which the shortest path has not yet been determined (denoted by U). Vertices in the second group are added to S in ascending order of shortest path length. During the addition process, the shortest path length from the source vertex v to any vertex in S is always maintained at no greater than the shortest path length from the source vertex v to any vertex in U. In addition, each vertex corresponds to a distance. The distance between vertices in S is the shortest path length from v to this vertex, and the distance between vertices in U is the current shortest path length from v to this vertex, including only vertices in S as intermediate vertices.

[0048] In this embodiment, the algorithm automatically obtains each water-using device in the 3D model as the starting point, the water meter as the ending point, and the divided grid lines as the movement route from the starting point to the ending point. Through the traversal path algorithm, multiple connecting routes are obtained. The route records the number of turns, line segment length, number of walls passed through, and number of intersections. The values ​​are multiplied by the corresponding weight ratio and converted into distance length. Finally, the shortest path is selected as the optimal path.

[0049] In this embodiment, the optimal path can also be calculated by extracting all nodes in the grid lines and determining the node corresponding to the water-using equipment in the 3D model as the starting point; adding the node as the starting point to a first set and adding all nodes except the starting point to a second set; calculating the distance between each node according to a preset weighting algorithm, repeatedly selecting the node 'a' from the second set that is closest to the node in the first set, adding node 'a' to the first set, deleting node 'a' from the second set, until all nodes have been traversed; and generating the corresponding optimal path according to the order of nodes selected from the second set and the starting point.

[0050] Specifically, the formula for calculating the weights in the above weighting algorithm is: f = ω1×f1 + ω2×f2 + ... + ωn×fn In the formula, f represents the distance length, n represents the total number of selection factors, f1, f2, ... and fn are the weights of each factor between two nodes, and ω1, ω2, ... and ωn are the weights corresponding to f1, f2, ... and fn, respectively.

[0051] This embodiment, based on the previous embodiment, describes in detail the process of using water-using devices in the 3D model as starting points and water meter devices in the 3D model as ending points for path planning on the grid lines to obtain the corresponding optimal path. This is achieved by extracting all nodes from the grid points; using the nodes corresponding to the water-using devices in the 3D model as starting points and the nodes corresponding to the water meter devices in the 3D model as ending points to generate multiple connected paths; calculating the distance of all connected paths according to a preset weighting algorithm, and selecting the connected path with the shortest distance as the corresponding optimal path. This method differs from purely manual 2D design in CAD and from the single-point generation functions for water supply pipelines currently available on the market. This method combines practical engineering experience and analysis of diverse residential floor plans, extracting a universal and flexible algorithm, and combining it with fast computing power, allowing designers to generate a water supply pipeline layout model for the entire building in a short time, greatly shortening the design cycle and more intuitively expressing design intent.

[0052] The residential water supply layout method in the embodiments of the present invention has been described above. The residential water supply layout device in the embodiments of the present invention will be described below. Please refer to [link / reference].

The meshing module 403 is used to divide the space in which the water supply pipe can travel into a mesh according to a preset visual algorithm, so as to obtain the mesh lines of the three-dimensional model. The path planning module 404 is used to perform path planning on the grid lines with the water-using equipment in the three-dimensional model as the starting point and the water meter equipment in the three-dimensional model as the ending point, to obtain the corresponding optimal path, and to use the optimal path as the residential water supply line of the three-dimensional model.
