Description

Technical Field

[0001] This application relates to the field of electronic digital data processing technology, specifically to a method, equipment, and medium for generating schematic diagrams of a wastewater system. Background Technology

[0002] In wastewater system design, the creation of system schematic diagrams is a crucial step in building water supply and drainage engineering. These diagrams need to clearly represent the spatial relationship between wastewater pipes and the building plan, as well as the topological connections between pipes, to ensure accurate construction by the contractor. However, current technologies primarily rely on manual drawing of wastewater system schematic diagrams, or only provide tools for generating isometric system diagrams. Designers must spend considerable time and effort drawing pipe, elevation, and equipment symbols one by one based on the floor plan. This process is tedious, time-consuming, and inefficient. Furthermore, when the floor plan is modified, the system schematic diagram often cannot be updated synchronously, leading to omissions or inconsistencies. This results in frequent rework and design changes after construction, increasing project costs and risks. Summary of the Invention

Based on the number of occupancy positions and the occupancy width corresponding to each riser main, the length of the elevation line corresponding to the elevation line is determined.

[0018] Based on the elevation position relationship and elevation spacing contained in the elevation information, multiple elevation lines with a length equal to the length of the first elevation line are generated sequentially upwards.

[0019] Based on the names of each elevation line read from the 3D model, the elevation name corresponding to the elevation line is generated.

[0020] In one implementation of this application, generating an end-device illustration connected to the pipeline diagram at a preset position on the pipeline diagram specifically includes:

[0051] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0053] like Figure 1 As shown in the embodiment of this application, a method for generating a schematic diagram of a wastewater system includes:

[0054] S101: Identify the wastewater pipes in the 3D model corresponding to the wastewater system, and determine the pipe type corresponding to the wastewater pipes based on the topological relationship of the wastewater pipes; wherein, the pipe type includes riser main pipes, horizontal main pipes and appliance branch pipes.

[0055] A 3D model is a virtual model constructed using computer technology that comprehensively presents a water supply and drainage system. Through a 3D model, the layout of the sewage and wastewater system in a real-world scenario can be realistically reflected, including the routing of pipes on each floor and the connection methods between different sanitary fixtures and pipes. The process involves reading sewage and wastewater pipes in the 3D model whose system type names contain "sewage" or "wastewater," and determining the different types of pipes based on the topological relationships between them. These pipe types include riser mains, horizontal mains, and appliance branch pipes.

[0056] In one embodiment, pipe type identification is based on the topological relationships between pipes. Specifically, since riser mains are typically vertical or nearly vertical to the ground and are used to connect sewage and wastewater discharges between different floors, when identifying sewage and wastewater pipes, riser mains are first identified based on pipes whose geometric direction makes an angle of not less than a first angle with the horizontal line and whose length is greater than a preset length. Here, the first angle is 85° and the length is 1m. Then, pipes whose geometric direction makes an angle of not more than a second angle with the horizontal line and satisfy a specified pipe topological relationship are identified as horizontal mains. The second angle is 45°. Horizontal mains are generally laid horizontally or nearly horizontally and are used to connect riser mains and appliance branch pipes within the same floor. Therefore, their angle with the horizontal line is small, and they must satisfy a specific specified pipe topological relationship. This specified pipe topological relationship includes three types: connecting two riser mains; connecting one end to a riser main and having no connection at the other end; and connecting one end to an appliance branch pipe and having no connection at the other end. After identifying the riser and horizontal main pipes, the pipes that connect to sanitary fixtures or floor drains and are connected to the riser or horizontal main pipe are identified as appliance branch pipes. The function of appliance branch pipes is to introduce wastewater from various sanitary fixtures or floor drains into the riser or horizontal main pipe, therefore their connection relationships have clear characteristics.

[0057] Accurate identification of different pipe types lays the foundation for generating subsequent wastewater system schematics. Accurate pipe type identification ensures that the layout and connections of the pipes in the generated schematics accurately reflect the actual wastewater system conditions.

[0058] S102: Read the elevation information from the linked model of the 3D model, and based on the base point selected by the user, generate elevation lines and the elevation names corresponding to each elevation line.

[0059] After identifying the pipe type, the next step is to read the elevation information from the linked model of the 3D model. Elevation information records the height and position of each floor and pipe in the wastewater system, which is crucial for accurately drawing the wastewater system schematic. Users can select a base point on the current drawing plane according to their actual needs; this base point will serve as the starting reference point for generating elevation lines. Based on the user-selected base point and the elevation information, elevation lines and their corresponding elevation names can be generated.

[0060] Specifically, first, read the elevations in the linked model whose names do not begin with "S" and whose names do not contain "BOF". In the construction industry, especially when using BIM software such as Revit, the letter "S" usually represents a structural elevation, which refers to the elevation of the upper surface of the structural floor slab. However, plumbing, HVAC, and electrical systems typically use architectural elevations, i.e., finished surface elevations, which include the total thickness of the floor slab, leveling layer, and finishing layer. There is a height difference between architectural and structural elevations. If the structural elevation is used to generate the system diagram, the height positioning of pipes will be inaccurate and will not match the actual building space. Therefore, excluding elevations starting with "S" ensures that the system schematic is generated based on the correct architectural elevation, guaranteeing the accuracy of the drawings. "BOF" refers to the ground floor elevation. These elevations are usually not standard functional floors and may be used to represent equipment foundations, pit bottoms, pipe trench bottoms, etc. They do not belong to the regular floor sequence. Excluding "BOF" maintains the clarity and standardization of the system schematic, showing only the main, habitable, or usable floor spaces. By filtering out irrelevant elevation information, the automatically generated system diagram is ensured to include only the main building floors related to the wastewater system design, and structural levels and reference surfaces with special constructions are filtered out, thereby guaranteeing the accuracy and professionalism of the generated results.

[0061] After reading the elevations, these elevations are sorted in ascending order according to their Z-coordinate values ​​to determine the vertical position of each elevation in the system, i.e., which is above and which is below. Then, the elevation spacing is determined, and the spacing between each elevation is equal.

[0062] Furthermore, the user-selected baseline is used as the location of the first elevation line. The user-selected baseline refers to the designer clicking a designated point in a blank area of ​​the 2D view using the mouse during the automatic drawing generation process. By allowing users to independently choose the starting point, they can decide which blank area to place the system schematic diagram in based on the overall layout of the drawing, avoiding overlap with floor plans, other system diagrams, or annotations. When multiple system schematic diagrams need to be generated for the same project (such as sewage systems, wastewater systems, and ventilation systems), users can select different baselines for each system to avoid mutual interference.

[0063] The first elevation line is generated using a preset line style, "P_Elevation Line," which corresponds to the lowest elevation line in the model. Then, based on the number of risers and main pipes and the preset buffer quantity, the space allocated to each riser is determined. The buffer quantity reserves space between risers; typically, it can be set to 2, meaning one riser width is reserved to the left of the leftmost riser and to the right of the rightmost riser, providing sufficient space for elevation labels, axis numbers, or other annotations at both ends, preventing text and graphics from crowding together. Each riser on the drawing needs a allocated space width to ensure sufficient space between adjacent risers and prevent overlap; typically, this space width can be set to 3000mm. Thus, based on the number and width of riser spaces, the elevation line length can be determined; the elevation line length is expressed as the product of the number and width of riser spaces. For example, if a system has 3 risers, then the elevation line length = (3 + 2) x 3000mm = 15000mm. This means that on the drawing, a horizontal line 15000mm long will be generated, and the 3 risers will be roughly evenly distributed on this line, with a blank margin of about 3000mm on each side.

[0064] It should be noted that if the schematic diagram includes multiple systems in addition to the wastewater system, the number of risers and main pipes to be occupied by the risers and main pipes in the multiple systems and the number of preset buffers should be determined when determining the length of the elevation line.

[0065] After determining the elevation line length, based on the elevation positional relationships and spacing contained in the elevation information, multiple elevation lines of the same length need to be generated sequentially upwards from the first elevation line. After generating the elevation lines, the corresponding elevation names are generated based on the names of each elevation line read from the 3D model. When generating the elevation names, an illustration is first generated at the leftmost endpoint of the elevation line, and then the elevation family is mirrored and copied to the right based on the vertical position of the detail line center.

[0066] S103: Starting from the first elevation line, generate the pipe lines corresponding to each pipe type.

[0067] After generating the elevation lines, the first elevation line serves as the starting point for drawing, and the corresponding pipe lines for each pipe type are generated sequentially. First, for riser mains, based on the previously identified riser main information, the sewage / wastewater pipe with riser number 1 is selected as the first riser to be drawn. If no number exists, any riser is automatically selected as the starting point. During riser drawing, a line with the same detail line type name as the pipe type name (i.e., the same Chinese characters) is used at the base point to draw the riser, and the riser length is consistent with the riser in the 3D model. After drawing the first riser, multiple riser lines corresponding to the riser main are generated sequentially according to the numbering order of the riser mains in the 3D model and the preset layout intervals, ensuring a certain horizontal spacing between each riser.

[0068] For horizontal main pipes, draw the horizontal main pipe lines at the corresponding elevation lines based on their connection relationships with vertical main pipes. For appliance branch pipes, identify the number of appliances connected to the appliance branch pipes in the 3D model, and then generate the appliance lines corresponding to the appliance branch pipes at the connection points of the vertical or horizontal main pipe lines according to the layout rules corresponding to the number of appliances.

[0069] Specifically, when there is only one appliance, a corresponding appliance line is generated at the connection point of the riser or horizontal pipe line. The appliance line consists of a broken line extending from the riser or horizontal pipe line and a horizontal line connecting the broken line. Generally, the appliance line can use a 45° 150mm broken line and a 1000mm horizontal line. When there are multiple appliances, a corresponding appliance line is also generated at the connection point of the riser or horizontal pipe line. The difference from connecting a single appliance is that a break symbol "P_Break Diagram_Standard_Plane" is placed at the end of the appliance line. The break symbol indicates that the line is not yet finished and other appliances can be connected later. Therefore, other appliance branches can be led out using the break symbol to continue connecting multiple sanitary appliances. For example... Figure 2 The diagram shows a pipeline. The leftmost appliance branch pipe connects to an appliance, and only broken lines and horizontal lines are used as appliance lines. The three appliance branch pipes on the right each have a broken symbol at the end, indicating that other appliances can be connected to them later.

[0070] S104: At the preset position of the pipeline diagram, generate the terminal equipment legend connected to the pipeline diagram, and mark the pipe diameter and riser number on the pipeline diagram to obtain the schematic diagram corresponding to the wastewater system.

[0071] After generating pipelines corresponding to different pipe types, it is necessary to generate terminal equipment legends connected to the pipeline lines at preset locations on the pipeline diagram. Terminal equipment legends are an important component of the wastewater system schematic diagram, showing the location and type of each terminal device in the system. For example, for appliance branch pipes connecting to sanitary fixtures, corresponding sanitary fixture legends are generated at their ends based on the type of sanitary fixture connected, such as toilets, washbasins, and floor drains. For pipes connecting specific equipment, corresponding equipment legends are generated, such as sewage lift pumps and wastewater treatment equipment. Simultaneously, pipe diameter and riser number markings are required on the pipeline diagram. Pipe diameter marking clarifies the size and specifications of each pipe, ensuring accurate selection of appropriate pipe materials during construction. When marking, the pipe diameter should be clearly indicated above or beside the pipeline line, such as "DN50" or "DN100". Riser number markings facilitate accurate identification and installation of each riser by construction personnel on-site. Riser pipes are numbered according to certain rules, and the riser numbers are marked above or next to the riser lines on the riser diagram, such as "WL-1" and "FL-2," where "WL" indicates a sewage riser and "FL" indicates a wastewater riser. These markings allow construction workers to clearly understand the pipe diameter and riser number of each pipe in the wastewater system, providing accurate guidance for construction.

[0072] In one embodiment, based on the type of sanitary appliance connected by the branch pipe in the 3D model, a sanitary appliance legend connected to the appliance diagram line is generated at the end of the branch pipe. For example... Figure 3 The diagram shows a branch pipe floor drain generation method, with a floor drain icon connected to the end of the appliance diagram.

[0073] An inspection port is a device used for inspecting and cleaning pipes, typically installed on risers or horizontal mains. In wastewater system schematics, inspection port symbols need to be generated at the corresponding locations on the pipe lines. Therefore, as... Figure 4 As shown, for floors with appliance branch pipes, an inspection port diagram is generated at a preset position (e.g., 1m) above the floor elevation line, connecting to the riser line. A vent cap is a device installed at the top of the riser to expel harmful gases from the pipe and ensure the normal operation of the drainage system. Therefore, as... Figure 5 As shown, in the schematic diagram of the wastewater system, a vent cap symbol needs to be generated at the top of the riser line to indicate that the riser is connected to the atmosphere.

[0074] In one embodiment, when marking pipe diameters on a pipeline diagram, the location of the markings needs to be determined first. Generally, for riser mains, marking points can be determined from the top floor downwards according to a preset floor interval. For example, a marking point can be set every two floors, with each floor determined based on the elevation difference between floors. Based on the marking points, the pipe diameter markings corresponding to the riser mains are generated. For appliance branch pipes, since their diameters are relatively small and their numbers are large, the specific pipe diameters can be marked dispersedly on the horizontal pipeline of each appliance branch pipe to ensure that construction personnel can accurately install each appliance branch pipe. When marking pipe diameters, a uniform marking format should be used, such as "DN" followed by the specific pipe diameter value. Figure 6 The diagram shows a pipe diameter marking scheme. The pipe diameter marking for appliance branch pipes is DN50, and the pipe diameter marking for riser main pipes is DN100.

[0075] After labeling is completed, a thorough check and review are necessary. This includes verifying that the labeled pipe diameter values ​​match the actual pipe diameter in the 3D model, confirming the accuracy of the labeling location, and ensuring the labeling format is standardized. The review process can be conducted jointly by designers and reviewers to ensure the accuracy and completeness of the pipe diameter labeling, providing a reliable basis for the construction of the wastewater system.

[0076] After generating the terminal equipment diagrams, labeling the pipe diameters, and labeling the risers, the corresponding schematic diagram of the wastewater system is obtained. This schematic diagram intuitively shows the layout, connection relationships, location of terminal equipment, pipe diameters, and riser numbers of each pipe in the wastewater system.
