Water supply and drainage machine room system diagram drawing is a time-consuming and error-prone difficult work in building water supply and drainage design. The pipeline in the machine room is dense and three-dimensional, and there are many equipment valves. Only relying on the plan cannot completely express the design content of the pipeline and equipment in the machine room. It is necessary to draw a system diagram combined with the plan to reflect the design situation and guide the construction.

[0032] For the sake of understanding, the specific flow of the embodiment of the application is described below, please refer to Figure 1 An embodiment of the method for generating the water supply and drainage machine room system diagram in the embodiment of the application includes the following steps:

[0033] 101. Obtain building room graph element information from the preset building information database based on the preset axial angle information, and generate a building room template graph according to the building room graph element information.

[0034] It can be understood that the execution subject of the application can be a water supply and drainage machine room system diagram generation device, and can also be a server, and the specific place is not limited. The embodiment of the application takes the server as the execution subject for example.

[0035] It should be noted that the building information is obtained from the building information database based on the building information model, wherein the building information model is based on the relevant information data of the building engineering project as the model basis, the building model is established, the real information of the building is simulated through digital information simulation, it has the characteristics of completeness, information consistency, visualization, coordination, simulation, optimization and drawing, wherein it should be noted that before the server uses the machine room system diagram function, the present model of the current model existing in the building information model is provided by the designer, the building room containing the name keyword exists in the link model, after the server runs this function, the server reads the above building room containing the name keyword and displays it in the pop-up interface, then the server is based on the preset axis angle information, wherein the axis angle information can be 45° or 30°, and then the server selects the building room of the system diagram to be generated through the mouse click event listened to, and generates the corresponding template diagram, such as Figure 2 Figure 2 To show the building room diagram element set, wherein it should be noted that Figure 2 The black frame part in the above is the outer wall of the building room.

[0036] 102. Based on the three-dimensional pipeline information in the building room graph element information, the water supply and drainage pipeline is generated, and the candidate water supply and drainage pipeline set corresponding to the building room template diagram is obtained.

[0037] Specifically, the server marks each area drawing in the building room template diagram based on the three-dimensional pipeline information in the building room graph element information. For example, the water supply and drainage pipeline data of region A in the three-dimensional pipeline information in the building room graph element information is exported, and the corresponding drawing is marked as the water supply and drainage pipeline data of region A, thereby facilitating the classification and saving in the later pipeline prefabrication process, wherein it should be noted that the water supply and drainage pipeline data at least includes pipeline length information data, pipeline diameter information, pipeline thickness information and pipeline connection point information, and then the server generates the pipeline according to the above water supply and drainage pipeline data, specifically, the server converts the pipeline segment in the three-dimensional space to a two-dimensional plane by coordinate transformation algorithm. Get the line segment on the two-dimensional plane. Get the candidate water supply and drainage pipeline system diagram corresponding to the building room template diagram, as shown in Figure 3 Figure 3 The candidate water supply and drainage pipeline system diagram generated by the server according to the building room template diagram.

[0038] 103. Based on the water supply and drainage equipment information in the building room graph element information, the project north direction is determined by analyzing the building room template diagram through the preset large sample diagram horizontal line algorithm.

[0039] ​​It should be noted that after the server calls the template graph method to generate the system graph in the drawing plane, the horizontal line method is used to find the line with the most repeated parallel lines in the two-to-two connection of the device position points as the horizontal line. Specifically, by connecting the two-to-two connection of the water supply and drainage device points, the line with the maximum parallel line set is found as the horizontal line, and then the project north direction is obtained, wherein the project north direction of the large-scale drawing is perpendicular to the horizontal line and the angle between the model project north and the horizontal line is less than or equal to 60 degrees, and then the corresponding project north direction is determined according to the horizontal line.

[0040] 104. Merge the candidate water supply and drainage pipeline set by the preset coincident line merging algorithm to obtain a target water supply and drainage pipeline set;

[0041] It should be noted that the coincident line merging algorithm refers to merging the generated lines that are collinear, have the same system type, the same size, and are actually connected. Specifically, the server analyzes the coincident line determination parameters of the candidate water supply and drainage pipeline by the above-mentioned coincident line merging algorithm, wherein the coincident line determination parameter is a judgment threshold parameter for identifying whether two connection lines are coincident lines according to a specific rule. The value of the coincident line determination parameter will affect the determination result of whether the two connection lines are a coincident line pair. It should be noted that the coincident line determination parameter can also be manually input by the user. After the user inputs the coincident line determination parameter, the processor records the coincident line determination parameter, and identifies the coincident line pair based on the coincident line determination parameter input by the user. At the same time, the server analyzes the coincidence type of the candidate water supply and drainage pipeline set to obtain the corresponding coincident category, wherein the coincident category includes collinear type, size type, and connection type. Then, the server performs coincident analysis based on the coincident category, and merges the candidate water supply and drainage pipeline set to obtain a target water supply and drainage pipeline set.

[0042] 105. Perform graph element matching based on the target water supply and drainage pipeline set to obtain a plurality of water supply and drainage accessory graph elements;

[0043] It should be noted that the characteristic data corresponding to each of the plurality of water supply and drainage accessory graph elements is the size of each graph element, and further, the size of each graph element is determined according to the shape category corresponding to each graph element. For example, if the graph element is a circle, then the size of the graph element is the radius and the height; if the graph element is a straight line, then the size of the graph element is the length, etc. Specifically, the server determines the corresponding graph element attribute data based on the target water supply and drainage pipeline set, wherein the graph element attribute data is the title name of the water supply and drainage accessory. It should be noted that the graph element attribute data set includes a plurality of preset graph element attribute data, and each preset graph element attribute data is a synonym, a near-synonym or a word with the same meaning of the graph name. For example, graph name, graph pattern name, graph paper name, etc. Then the server obtains the component associated with each graph element from the building information model component database, and determines the shape category to which each graph element belongs; according to the determination result, the arrangement rule between the graph elements with the same shape category is analyzed, and when the arrangement rule matches any one of the preset arrangement rules in the preset arrangement rule set, the corresponding water supply and drainage accessory component information is obtained from the building information model component database according to the arrangement rule. Finally, the server matches the graph elements through the water supply and drainage accessory component information, and obtains a plurality of water supply and drainage accessory graph elements.

[0044] 106. Generating a water supply and drainage machine room system diagram based on the plurality of water supply and drainage accessory graph elements and the target water supply and drainage pipeline set.

[0045] The server establishes a building information model family with a room as the smallest design graph element, adds the function information and component information of the room as characteristic values to the building information model family, filters and extracts the components of the building information model family according to the task requirements of the building design and the characteristic values of the water supply and drainage equipment, forms a project graph element library, and then divides the grid based on the building contour plane, subdivides according to the function and area of the building plane, and finally obtains a grid division graph. The water supply and drainage accessory graph elements are arranged on the special nodes of the grid space, and then the server generates a water supply and drainage machine room system diagram based on the target water supply and drainage pipeline set.

[0046] In the embodiment of the application, the server performs coincidence type analysis on the candidate water supply and drainage pipeline set to obtain a corresponding coincidability category, wherein the coincidability category includes collinear type, size type, connection type and the like. Then, the server performs coincidability analysis according to the coincidability category and pipeline merging on the candidate water supply and drainage pipeline set to obtain the target water supply and drainage pipeline set. The server generalizes the algorithm in the process of drawing the traditional water supply and drainage machine room system diagram, so that the server can complete the drawing of the water supply and drainage machine room system diagram through the algorithm, which can replace manual drawing and manual labeling, improve the efficiency of generating the water supply and drainage machine room system diagram, and ensure the accuracy of the drawing result.

[0054] It should be noted that the server finds the line of the maximum parallel line set as the horizontal line through the two-by-two connection of the water supply and drainage equipment points, and then obtains the project north direction, wherein, the large drawing horizontal line algorithm is that the line with the most repeated parallel lines in the two-by-two connection of the drawing is taken as the horizontal line, the project north direction of the large drawing is perpendicular to the horizontal line and the angle with the project north of the building room template drawing is less than or equal to 60 degrees, specifically, in the embodiment of the application, the server performs slope analysis on each line in the point connection set, wherein the server performs coordinate analysis on the two endpoints of each line, and then determines the corresponding slope according to the two endpoint coordinates of each line, so that the server performs parallel line analysis according to the corresponding slope of each line, obtains multiple parallel line sets, and determines the corresponding line number by analyzing the line number of each parallel line set, and selects the target parallel line set with the largest line number, and determines the direction perpendicular to the straight line of any line in the target parallel line set as the project north direction according to the slope of each parallel line in the target parallel line set.

[0058] 405, performing graph element matching based on the target water supply and drainage pipeline set to obtain a plurality of water supply and drainage accessory graph elements;

[0059] Specifically, the server performs pipe accessory matching based on the target water supply and drainage pipeline set to determine a corresponding pipe accessory set; the server performs water supply and drainage equipment matching on the pipe accessory set through a preset equipment relationship configuration table to determine a corresponding water supply and drainage equipment set; and the server performs graph element matching according to the water supply and drainage equipment set and the pipe accessory set to obtain a plurality of corresponding water supply and drainage accessory graph elements.

[0060] It should be noted that the water supply pipe accessory is a general term for opening and closing and adjusting devices installed on pipes and equipment. It is generally divided into two categories: water distribution accessories and control accessories. Water distribution accessories, such as various water nozzles installed on sanitary fixtures and water points, are used to adjust and distribute water flow. Control accessories are used to adjust water flow, water pressure, determine water flow, and change water flow direction, such as gate valves, check valves, and float ball valves. In the embodiments of the present application, the server determines the pipe accessory set by performing accessory matching on the corresponding water supply and drainage pipeline. Specifically, the server performs pipe accessory matching according to the pipe type and size type of the water supply and drainage pipeline.

[0065] The text information of the pipe name, elevation and length size is attached to the corresponding pipe, and the specific position thereof near the pipe has uncertainty, and the text information of two or more pipes often partially or completely overlaps, which is relatively chaotic and affects the neatness of the interface. On the other hand, the text information of the pipe name, elevation and length size under the three-dimensional model is arranged in parallel to the spatial trend of the pipe, but the text information printed out after adjustment to the isometric direction is not necessarily parallel to the pipe. In the embodiment of the application, the server acquires pipe parameter information from a preset building information database, wherein the pipe parameter information comprises pipe abbreviation name, pipe size data and pipe elevation data.

[0066] 408、acquire pipe parameter information from a preset building information database, wherein the pipe parameter information comprises pipe abbreviation name, pipe size data and pipe elevation data;

[0067] Specifically, the server analyzes the center point position of each water supply and drainage pipeline in the target water supply and drainage pipeline set in the water supply and drainage plant system diagram through a preset labeling avoidance algorithm to determine the center point position corresponding to each water supply and drainage pipeline. The server labels the pipe abbreviation name in the pipe parameter information at the center point position, labels the pipe size data at one side of the center point position according to a preset distance, and labels the pipe elevation data at the other side of the center point position according to a preset distance.

[0068] It should be noted that the labeling avoidance algorithm means that the pipe size, pipe system abbreviation and pipe height are arranged at the center point position of the corresponding pipe.
