Description

Technical Field

[0001] The present invention relates to the technical field of intermittent drainage and water recovery, and particularly relates to an automatic positioning method and system for funnels for drainage, water release and air release. Background Art

[0002] The statements in this part merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] In industrial plants represented by thermal power plants, there are both civil structures and process pipelines. Among them, common civil structures include columns and crossbeams between columns, etc.; process pipelines are supported and rooted on the civil structures. Process pipelines, such as hot medium pipelines like steam pipelines or hot water pipelines, need to be provided with drain pipelines, water release pipelines and air release pipelines. Among them, drain pipelines and water release pipelines can also be collectively referred to as drainage and water release pipelines. When the process pipeline releases air, it is usually proved that the air has been released when there is liquid flowing out, so the air release pipeline also needs to be connected to a funnel.

[0004] The diameters of the drainage and water release pipelines and the air release pipeline are smaller than those of the hot medium pipeline. The main functions include: draining the water condensed in the steam pipeline to prevent the formation of two-phase flow and thus causing pipeline vibration; draining the water in the pipeline during shutdown; draining the water in the pipeline after a hydrostatic test; driving the air in the pipeline away during a hydrostatic test, etc. The drainage and water release pipeline is connected to the process pipeline through a tee, or directly welded by drilling holes in the hot medium pipeline. The air release pipeline is connected to the process pipeline through a tee, or directly welded by drilling holes in the hot medium pipeline. The connection point between the drainage and water release pipeline and the process pipeline is called the drainage and water release point, and the connection point between the air release pipeline and the process pipeline is called the air release point. Among them, the connection point between the drain pipeline and the process pipeline is called the drain point, and the connection point between the water release pipeline and the process pipeline is called the water release point.

[0005] According to the design code for steam and water pipelines in thermal power plants, the layout position of the water release and air release funnels should ensure that it does not endanger the safety of equipment and personnel, avoid water backflow in the funnel, and enable the flow condition of the working medium to be seen during operation. Currently, in the design of steam and water pipelines in thermal power plants, common funnels include independent drainage funnels and centralized funnels;

[0006] Since the positions of drain and vent points mainly depend on the design and layout requirements of process pipelines, the positions of drain and vent points are irregular. Therefore, during the design phase, the positioning of drainage funnels in the main plant has always been a major problem. Existing design methods lack an overall optimization method for funnel layout and a statistical method for the material consumption of pipelines with relatively small diameters (usually with a nominal diameter less than or equal to 80 mm), such as drain and vent pipelines. Therefore, during the current design of thermal power plants, usually only in the system diagram, a drain point is connected to an independent drainage funnel, a water discharge point is connected to an independent drainage funnel, and a vent point is connected to an independent drainage funnel. Qualified design units do not specify the funnel position during the construction drawing design phase and usually leave it to the on-site construction unit for secondary design. During the construction phase, construction personnel select appropriate drainage funnels and their layout positions according to the actual positions and quantities of drain and vent points of each process pipeline at the construction site. However, since the construction unit does not accurately grasp the design intent of the design unit, the drainage funnels installed on-site often occupy the installation space of other pipelines, electrical, thermal control equipment, or cable trays that need to be installed later, resulting in potential collision problems between the equipment, pipelines, or cable trays to be installed that did not collide in the design model at the construction site. To avoid the demolition and rework of the funnels already installed on-site, it is necessary to make design changes to the equipment, pipelines, or cable trays to be installed in the next step, thus increasing the design workload and prolonging the construction period.

[0007] In addition, the drainage funnels installed at the construction site lack a three-dimensional model of forward design. When feeding back to the design unit for reverse modeling, the installation positions of the funnels and small pipelines are often not clearly described. Eventually, when the general contractor for the project conducts digital handover to the construction unit, the content included in the transferred model is incomplete. Furthermore, there is a large deviation between the three-dimensional model used during the owner's operation and maintenance and the physical model, resulting in the inability to correctly carry out the operation and maintenance functions based on the model, seriously affecting the improvement of operation and maintenance efficiency by using digital means.

[0008] Previous technologies have disclosed a centralized funnel. By improving the physical structure of the funnel, it is possible to connect multiple drain and vent points to a centrally arranged funnel through drain pipelines, water discharge pipelines, and / or vent pipelines. However, similar to the layout of independent drainage funnels, existing design methods also lack an overall optimization method or an automatic positioning method for the layout of the centralized funnel; for the case of connecting multiple drain and vent points to a centrally arranged funnel through drain pipelines, vent pipelines, etc. with relatively small diameters (usually with a nominal diameter less than or equal to 80 mm), there is also a lack of a statistical method for the material consumption of these pipelines. Summary of the Invention

[0009] To solve the above problems, the present invention proposes an automatic positioning method and system for funnels used for drainage and air release. By structurally dividing the plant space with columns in the plant building, it is possible to automatically position the funnels at the design stage, improve the accuracy and integrity of the design models of the drainage funnels, the small drainage pipelines, and the digital handover models, avoid the secondary random design by construction personnel, and thus reduce the collisions of installation equipment, pipelines, or bridges at the construction site.

[0010] In some embodiments, the following technical solutions are adopted:

[0011] An automatic positioning method for funnels used for drainage and air release, comprising:

[0012] For each floor of the plant building to be designed, it is divided into several minimum space units according to the columns, and each minimum space unit is surrounded by four columns;

[0013] Select the origin of coordinates and establish a three-dimensional coordinate system;

[0014] For each minimum space unit, determine the potential funnel installation positions on the columns; with the goal of minimizing the total weight of all the drainage pipelines, water discharge pipelines, and / or air release pipelines reaching a certain potential funnel installation position within each minimum space unit, determine the local optimal position and the sub-optimal position of the funnel installation within each corresponding minimum space unit.

[0015] Further, after determining the local optimal position and the sub-optimal position of the funnel installation within each corresponding minimum space unit, it further includes: merging the minimum space units according to the set rules to obtain the globally optimized position of the funnel installation.

[0016] Further, the merging of the minimum space units according to the set rules specifically includes:

[0017] Sort the minimum space units according to the number of interfaces of the drainage pipelines, water discharge pipelines, and / or air release pipelines within each minimum space unit; select the top K minimum space units with more interfaces as the seed units, and the remaining minimum space units as non-seed units;

[0018] Each seed unit forms a group. For the non-seed units on the same floor as the seed units, divide them into the corresponding groups according to the principle of the minimum weighted nominal distance from the seed units to obtain K group space units;

[0019] For each group space unit, determine the potential funnel installation positions on the columns; with the goal of minimizing the total weight of the pipelines of all the drainage pipelines, water discharge pipelines, and / or air release pipelines reaching a certain potential funnel installation position, determine the globally optimal position and the sub-optimal position of the funnel installation within each corresponding group space unit.

[0020] Further, the total weight of all the drain pipes, water discharge pipes, and / or air vent pipes reaching a potential funnel installation position refers to the sum of the products of the unit pipe weight corresponding to the pipe diameter at each drain point, water discharge point, and / or air vent point and the pipe length of each drain pipe, water discharge pipe, and / or air vent pipe; the pipe length of each drain pipe, water discharge pipe, and / or air vent pipe is represented by the distance between two spatial points formed by each drain point, water discharge point, and / or air vent point and the coordinates of the center point of the potential funnel installation, and the distance between the two spatial points is obtained by taking the absolute value of the difference between the x-axis, y-axis, and z-axis coordinates of the drain point, water discharge point, and / or air vent point coordinates and the coordinates of the center point of the potential funnel installation, and then summing them up.

[0021] Further, the weighted nominal distance refers to:

[0022] The product of the average distance between the funnel installation positions of the non-seed unit and the funnel installation positions of the seed unit and the number of interfaces of the drain pipes, water discharge pipes, and / or air vent pipes within the non-seed unit;

[0023] Among them, the average distance between the funnel installation positions of the non-seed unit and the funnel installation positions of the seed unit is specifically:

[0024] The average of the distance between the locally optimal position of the funnel of the non-seed unit and the locally optimal position of the funnel of the seed unit, the distance between the locally optimal position of the funnel of the non-seed unit and the locally sub-optimal position of the funnel of the seed unit, the distance between the locally sub-optimal position of the funnel of the non-seed unit and the locally optimal position of the funnel of the seed unit, and the distance between the locally sub-optimal position of the funnel of the non-seed unit and the locally sub-optimal position of the funnel of the seed unit.

[0025] Further, for each group of spatial units, determining the potential funnel installation positions on the columns specifically includes:

[0026] Taking the locally optimal and sub-optimal positions of the funnel of the seed unit, and the locally optimal and sub-optimal positions of the funnel of the non-seed unit with the largest number of interfaces of the drain pipes, water discharge pipes, and / or air vent pipes as the potential funnel installation positions of the group of spatial units.

[0027] Further, the merging of the smallest spatial units according to the set rules specifically includes:

[0028] Counting the sum of the number of interfaces of the drain pipes, water discharge pipes, and / or air vent pipes corresponding to the funnels at the locally optimal or sub-optimal positions on each column; among them, when the locally optimal position and the locally sub-optimal position of the funnel within the same smallest spatial unit are on different sides of the same column, only one funnel is taken for counting;

[0029] The first P columns with a large number of interfaces are selected as seed columns; with the seed columns as the center, the minimum space units are merged according to the set rules to obtain a merged space unit;

[0030] For each merged spatial unit, determine the potential funnel installation position on the column; with the goal of minimizing the total weight of all drain pipes, drain pipes and / or vent pipes reaching a potential funnel installation position, determine the global optimal position and suboptimal position of the funnel installation position in each corresponding group spatial unit.

[0031] Furthermore, with the seed column as the center, the minimum space units are merged according to the set rules, specifically:

[0032] With the seed column as the center, the smallest space units are merged in the shape of a sun, a field, or a nine-square grid; or, space merging is achieved by manually selecting the smallest space units to perform a custom space combination.

[0033] Furthermore, for each minimum space unit, determine the potential funnel installation position on the column; specifically including:

[0034] Determine the ground center coordinates of the columns on each floor of the factory building to be designed, as well as the coordinates of the pipeline drainage points, water discharge points and / or pipeline venting points;

[0035] For each minimum space unit, the funnel is installed on the side of the column facing the inside of the minimum space unit; each column that encloses the minimum space unit has only two sides facing the inside of the minimum space unit. Therefore, based on the ground center point coordinates of each column, considering the installation distance of the funnel on the corresponding side of the column, the potential funnel installation positions are determined respectively.

[0036] Furthermore, after determining the local optimal position and suboptimal position of the funnel installation in each minimum space unit or obtaining the global optimal position of the funnel installation, it also includes: performing adaptability checks on the obtained funnel installation positions in order according to the sorting, and selecting the final funnel installation position.

[0037] Furthermore, after the final funnel installation position is selected, it also includes:

[0038] On the basis of the general model of the funnel, the number of interfaces of the funnel is input according to the number of drain points, water discharge points and / or air discharge points to be connected, as the personalized configuration of the actual funnel, and the three-dimensional model of the funnel is generated, and imported into the design model according to the final installation position of the funnel;

[0039] or,

[0040] After selecting the final installation position of the funnel, it further includes:

[0041] According to the final installation position of the funnel, calculate the layout lengths of the drain pipe, the water discharge pipe, and / or the air vent pipe, and then multiply by the allowance factor to obtain the material quantities of the drain pipe, the water discharge pipe, and / or the air vent pipe.

[0042] In some other embodiments, the following technical solution is adopted:

[0043] An automatic positioning system for a funnel for draining water, discharging water, and venting air, comprising:

[0044] A minimum space unit division module, which is used to divide each floor of the plant to be designed into several minimum space units according to the columns, and each minimum space unit is surrounded by four columns;

[0045] A coordinate system construction module, which is used to select the coordinate origin and establish a three-dimensional coordinate system;

[0046] A funnel installation position local optimization module, which is used to determine the potential funnel installation positions on the columns for each minimum space unit; aiming at minimizing the total weight of all drain pipes, water discharge pipes, and / or air vent pipes reaching a certain potential funnel installation position within each minimum space unit, determine the local optimal position and the sub-optimal position of the funnel installation within each corresponding minimum space unit.

[0047] A funnel installation position global optimization module, which is used to merge the minimum space units according to the set rules, and then sort the funnel installation positions within the merged group of space units to obtain the global optimal position and the sub-optimal position of the funnel installation.

[0048] Furthermore, the system further includes:

[0049] A log recording and three-dimensional heat map display module, which is used to record the data during the automatic positioning process and generate a three-dimensional heat map;

[0050] A funnel model and adaptability check module, which is used to automatically generate a personalized configured funnel model based on the general funnel model by inputting the number of interfaces of the funnel, and perform an adaptability check on the optimal position and the sub-optimal position recommended by the optimization module.

[0051] Compared with the prior art, the beneficial effects of the present invention are:

[0052] (1) The automatic positioning method of the funnel for draining water and gas of the present invention traverses through the smallest spatial units. On the one hand, it can screen out the number of pipeline water drainage points, water release points or gas release points in the single-grid space of each smallest spatial unit, playing a role of taking stock. On the other hand, it can screen out the optimal path of the water drainage and release pipelines in each smallest spatial unit, as well as the locally optimal and sub-optimal layout positions of the centralized funnels.

[0053] (2) With the minimum total pipeline weight as the optimization goal, the minimum steel consumption is achieved; the number of funnel interfaces is reasonably designed according to the number of pipeline interfaces, ensuring the accuracy of the design.

[0054] (3) Further, the smallest spatial units can be merged according to the set rules, and then the installation positions of the funnels in the merged group of spatial units are sorted to obtain the globally optimal and sub-optimal positions for funnel installation, further reducing the total pipeline weight through merging.

[0055] (4) The present invention automatically positions the centralized funnel in the design stage, takes the water drainage point, water release point or gas release point as the starting point, and the centralized funnel as the end point, and automatically routes and arranges the small pipelines, thus deepening the design model of the funnel for draining water and gas and the related small water drainage and release pipelines, improving the design accuracy, effectively reducing the on-site secondary design of construction personnel, reducing the randomness of secondary design, and further reducing the collisions on the construction site, improving the accuracy and integrity of digital handover.

[0056] (5) Since the number of pipeline water drainage points, water release points or gas release points in each smallest spatial unit or each group of spatial units is recorded in the investigation log, it is convenient to realize the parametric design of the centralized funnel, that is: after establishing a general funnel model, according to the number of interfaces of the pipeline water drainage pipeline, water release pipeline or gas release pipeline input, a customized funnel model at the funnel installation position can be automatically generated.

[0064] Embodiment 1

[0065] In one or more embodiments, an automatic positioning method for the funnel used for water drainage and air release is disclosed. Referring to Figure 4 , the method includes the following steps:

[0066] Step (1): For each floor of the plant to be designed, it is divided into several minimum space units according to the columns, and each minimum space unit is surrounded by four columns.

[0067] In this embodiment, the main plant is supported by multiple columns, and it is defined that the column number of each column consists of letters and numbers. As an implementation manner, the plane space of the main plant includes two dimensions, namely the width direction and the length direction of the main plant. The space in the height direction of the main plant is marked with capital Roman numerals, the space in the width direction of the main plant is marked with capital English letters, and the space in the length direction of the main plant is marked with Arabic numerals.

[0068] In this embodiment, the main plant is divided into multiple minimum space units according to the floors and columns. Combining Figure 1 , A, B, and C represent the A bay, B bay, and C bay in the width direction of the main plant, and 01, 02, 03, 04, 05, and 06 represent the 01 bay, 02 bay, 03 bay, 04 bay, 05 bay, and 06 bay in the length direction of the main plant. Ⅰ, Ⅱ, and Ⅲ represent the first floor (i.e., the first above-ground floor), the second floor (i.e., the second above-ground floor), and the third floor (i.e., the third above-ground floor) in the height direction of the main plant, and -Ⅰ, -Ⅱ, and -Ⅲ represent the first basement floor (i.e., the first underground floor), the second basement floor (i.e., the second underground floor), and the third basement floor (i.e., the third underground floor) in the height direction of the main plant.

[0069] Number each floor of the designed plant building, and number the columns on each floor in the length direction and the width direction to obtain numbers that can represent the positions of each column. For example: Figure 1 For the column in the lower left corner, assuming it is a column on the first floor of the main plant building, its number is Ⅰ-A01.

[0070] In the following embodiments, for the sake of simplicity of description, the length of each span in the length direction is 10 meters, the length of each span in the width direction is also 10 meters, and the height of each floor of the main plant building is also 10 meters.

[0071] Step (2): Select the origin of coordinates, establish a three-dimensional coordinate system, and determine the ground center point coordinates of the columns on each floor of the plant building to be designed, as well as the coordinates of the pipeline drain points, water discharge points, and / or air release points; specifically, only a single drain point, water discharge point, or air release point can be considered, or any two of the three can be considered, or all of the drain point, water discharge point, or air release point can be considered. In the following embodiments, the drain point, water discharge point, or air release point is taken as an example for description; the corresponding pipelines are drain pipelines, water discharge pipelines, or air release pipelines (referred to as drain and water discharge pipelines or air release pipelines).

[0072] In this embodiment, the center point of column A01 at the zero-meter height on the first floor of the main plant building is taken as the origin of coordinates, the length direction is the x-axis, the width direction is the y-axis, and the height direction is the z-axis.

[0073] Determine the column center point coordinates of each column at the ground of each floor of the main plant building and the coordinates of the pipeline drain points and air release points, and store them in the database.

[0074] Step (3): Number each pipeline drain point or pipeline air release point according to the rules;

[0075] Specifically, calculate the sum of the coordinate values of each pipeline drain point or air release point in the x, y, and z directions as a characteristic attribute value for comprehensively measuring the distance between the pipeline drain point or air release point and the origin of coordinates; therefore, further sort and number the coordinates of each pipeline drain point or air release point according to the magnitude rule of the sum of the coordinate values in the x, y, and z directions, which is convenient for distinguishing the coordinates of each pipeline drain point or air release point and is convenient for further implementing the automatic positioning method described in this patent through computer programming;

[0076] Specifically, set a variable Σ in the database, automatically calculate the sum of the coordinate values of each pipeline drain point or air release point in the x, y, and z directions, and sort the drain points or air release points in ascending order. The serial number of the automatic sorting is the number of the pipeline drain point or air release point.

[0077] When the sum of the coordinate values of two pipeline drainage and water release points or air release points in the x, y, and z directions is equal, they are sorted in ascending order of the x-direction coordinate value; when the sum of the coordinate values of two pipeline drainage and water release points or air release points in the x, y, and z directions is equal and the x-direction coordinate values are equal, they are sorted in ascending order of the y-direction coordinate value.

[0078] Step (4): For each minimum space unit, determine the potential funnel installation positions on the columns; with the goal of minimizing the total weight of all drainage pipelines, water release pipelines, and / or air release pipelines reaching a certain potential funnel installation position within each minimum space unit, determine the locally optimal position and sub-optimal position of the funnel installation within each corresponding minimum space unit.

[0079] In this embodiment, based on the ground center point coordinates of each column enclosing each minimum space unit, considering the installation distance of the funnel on the column, multiple potential funnel installation center point coordinates are determined.

[0080] Since there is a certain distance for the installation of the funnel on the column, therefore, in combination with Figure 3 , the specific consideration of the installation distance of the funnel on the column is as follows: Denote the distance between the funnel center and each floor of the main plant building as h0, the installation distance between the funnel center and the column center in the x-axis direction as a0, and the installation distance between the funnel center and the column center in the y-axis direction as b0. Among them, Figure 3 The circles in represent the potential positions of the funnels, and the rectangles represent the columns. Optionally, the funnel adopts the centralized funnel described in ZL201720034509.7 or CN202122034019.6.

[0081] For each minimum space unit, the funnel is installed on the side of the column facing the inside of the minimum space unit; each column enclosing the minimum space unit has only two sides facing the inside of the minimum space unit. Therefore, based on the ground center point coordinates of each column, considering the installation distance of the funnel on the corresponding side of the column, the potential funnel installation center point coordinates are determined respectively.

[0082] For each potential funnel installation center point coordinate, calculate the distance of each drainage pipeline and air release pipeline formed between each drainage and water release point or air release point in the space unit and the potential funnel installation center point coordinate; it should be noted that because the general rule of pipeline layout is to be regularly arranged along the x-axis, y-axis, and z-axis directions, rather than directly connecting two points in space, in this method, the distance calculation between two points in space representing the length of the drainage pipeline or air release pipeline adopts the broken line distance, that is, the absolute values of the differences in the x-axis coordinates, y-axis coordinates, and z-axis coordinates between two points are summed respectively, rather than the straight-line distance between two points.

[0083] Multiply the unit weight per meter of the pipeline corresponding to each drainage or venting point by the length of each drainage or venting pipeline to obtain the total weight of each drainage or venting pipeline. Further, within the spatial unit, taking each potential funnel installation center point coordinate as the end point, calculate the sum of the pipeline weights of all the drainage and venting pipelines corresponding to the potential funnel installation center point coordinate, to obtain the total pipeline weight corresponding to the potential funnel installation center point within the spatial unit. According to the magnitude of the above pipeline total weight, sort each potential funnel installation center point coordinate. Among them, the coordinate corresponding to the minimum pipeline total weight is used as the locally optimal position for funnel installation within the spatial unit, and the coordinate corresponding to the second smallest pipeline total weight is used as the locally sub-optimal position for funnel installation within the spatial unit.

[0084] Traverse each minimum spatial unit to obtain the locally optimal position and locally sub-optimal position of funnel installation within each minimum spatial unit, as well as the number of interfaces, pipeline length, and total pipeline weight of the drainage and venting pipelines corresponding to the above funnel positions. Among them, the total pipeline weight is the sum of the products of the unit weight per meter of the pipeline corresponding to each drainage and venting pipeline within the spatial unit and the pipeline lengths of each drainage and venting pipeline.

[0085] Specifically, in combination with Figure 2 , taking the minimum spatial unit on the second floor of the main workshop as an example for illustration, the circles in the figure represent the positions of the drainage points, water discharge points, or venting points.

[0086] 1) Columns Ⅱ-A02, Ⅱ-A03, Ⅱ-B02, and Ⅱ-B03 enclose a minimum spatial unit; there are 7 drainage or venting points within this minimum spatial unit, and their coordinates are (12, 2, 15), (11, 5, 17), (11, 8, 14), (13, 9, 18), (15, 8, 16), (18, 8, 15), and (19, 3, 19), respectively, as the starting point coordinates.

[0087] The coordinates of the center points of columns Ⅱ-A02, Ⅱ-A03, Ⅱ-B02, and Ⅱ-B03 are (10, 0, 10), (20, 0, 10), (10, 10, 10), and (20, 10, 10), respectively, as the initial end point coordinates.

[0088] 2) Then, considering the installation distance of the funnel on the corresponding side of the column, refine the initial end point coordinates to determine the final end point coordinates.

[0089] In this embodiment, the distance between the funnel center and the ground of each floor of the main workshop is recorded as 1 meter, the installation distance between the funnel center and the column center in the x-axis direction is recorded as 1 meter, and the installation distance between the funnel center and the column center in the y-axis direction is recorded as 2 meters.

[0090] 3) After refinement, at different lateral directions of the column, at the possible funnel installation positions, the potential central coordinate positions of the funnel include:

[0091] For column No. Ⅱ-A02, the potential position on the side facing the minimum space unit along the x-axis is (11, 0, 11), and the potential position on the side facing the minimum space unit along the y-axis is (10, 2, 11);

[0092] For column No. Ⅱ-A03, the potential position on the side facing the minimum space unit along the x-axis is (19, 0, 11), and the potential position on the side facing the minimum space unit along the y-axis is (20, 2, 11);

[0093] For column No. Ⅱ-B02, the potential position on the side facing the minimum space unit along the x-axis is (11, 10, 11), and the potential position on the side facing the minimum space unit along the y-axis is (10, 8, 11);

[0094] For column No. Ⅱ-B03, the potential position on the side facing the minimum space unit along the x-axis is (19, 10, 11), and the potential position on the side facing the minimum space unit along the y-axis is (20, 8, 11).

[0095] The above potential position coordinates are all used as the final end coordinates.

[0096] 4) Calculate the sum of the distances between each starting coordinate and each final end coordinate respectively; it should be noted that when calculating the distance between each starting point (drainage point or air release point) and the end coordinate, take the absolute value of the coordinate difference in the x-axis direction, add the absolute value of the coordinate difference in the y-axis direction, and then add the absolute value of the coordinate difference in the z-axis direction. The sum obtained is the distance between the starting coordinate and the end coordinate. This distance represents the length of the drainage pipeline.

[0097] For example, the distances from seven water drainage or gas venting points (12, 2, 15), (11, 5, 17), (11, 8, 14), (13, 9, 18), (15, 8, 16), (18, 8, 15), (19, 3, 19) to the potential position (11, 0, 11) on the side of the smallest spatial unit facing the x-axis of column number Ⅱ-A02 are respectively: |12 - 11| + |2 - 0| + |15 - 11| = 7 (meters), |11 - 11| + |5 - 0| + |17 - 11| = 11 (meters), |11 - 11| + |8 - 0| + |14 - 11| = 11 (meters), |13 - 11| + |9 - 0| + |18 - 11| = 18 (meters), |15 - 11| + |8 - 0| + |16 - 11| = 17 (meters), |18 - 11| + |8 - 0| + |15 - 11| = 19 (meters), |19 - 11| + |3 - 0| + |19 - 11| = 19 (meters). The corresponding pipe diameters of the above seven water drainage or gas venting points are respectively φ32×3 (outer diameter 32 mm, wall thickness 3 mm), φ32×3, φ32×3, φ32×3, φ25×2, φ25×2, and φ25×2. The corresponding single weights per meter of the pipes are respectively 2.145 kg / m, 2.145 kg / m, 2.145 kg / m, 2.145 kg / m, 1.134 kg / m, 1.134 kg / m, and 1.134 kg / m. Multiply the single weight per meter of the pipe corresponding to each water drainage or gas venting point by the length of each water drainage pipe or gas venting pipe to obtain the pipe weight of each water drainage pipe or gas venting pipe. Then sum up the pipe weights of each water drainage pipe or gas venting pipe to obtain the total pipe weight of 2.145×7 + 2.145×11 + 2.145×11 + 2.145×

[0098] 18 + 1.134×17 + 1.134×19 + 1.134×19 = 163.185 (kilograms).

[0099] The distances from seven water drainage or gas venting points (12, 2, 15), (11, 5, 17), (11, 8, 14), (13, 9, 18), (15, 8, 16), (18, 8, 15), (19, 3, 19) to the potential position (10, 2, 11) on the side of the smallest spatial unit facing the y-axis of column number Ⅱ-A02 are respectively: |12 - 10| + |2 - 2| + |15 - 11| = 6, |11 - 10| + |5 - 2| + |17 - 11| = 10, |11 - 10| + |8 - 2| + |14 - 11| = 10, |13 - 10| + |9 - 2| + |

[0100] |18 - 11| = 17, |15 - 10| + |8 - 2| + |16 - 11| = 16, |18 - 10| + |8 - 2| + |15 - 11| = 18, |19 - 10| + |3 - 2| + |19 - 11| = 18. Multiply the weight per meter of the pipe corresponding to each drainage or venting point by the length of each drainage or venting pipe to obtain the pipe weight of each drainage or venting pipe. Then sum up the pipe weights of each drainage or venting pipe to get the total pipe weight of 151.203 kg reaching the potential position on the side of the smallest spatial unit.

[0101] Similarly, obtain the total pipe weights of the above 7 drainage or venting points reaching the potential positions on the sides of other smallest spatial units.

[0102] Sort the coordinates of each potential funnel installation center point according to the magnitudes of the above total pipe weights; the coordinates of the center point of the potential position corresponding to the smallest total pipe weight are used as the locally optimal position for funnel installation, and the coordinates of the center point corresponding to the second smallest total pipe weight are used as the locally sub - optimal position for funnel installation.

[0103] In this embodiment, by traversing the smallest spatial units, on the one hand, the number of drainage or venting points of the pipes within each smallest spatial unit can be screened out, which plays a role in taking inventory. On the other hand, the optimal routing of the drainage pipes within each smallest spatial unit and the optimal layout position of the funnels can be screened out.

[0104] Step (5): Generate a log of inspections of the smallest spatial units and a three - dimensional heat map.

[0105] After traversing and locally optimizing all the smallest spatial units, output a log of inspections of the smallest spatial units and a three - dimensional heat map.

[0106] The log of inspections of the smallest spatial units includes at least: the coordinate attributes of the smallest spatial units, the number of drainage or venting points within the smallest spatial units, the optimal / sub - optimal funnel layout positions within the smallest spatial units, and the total length of the optimal routing of the drainage pipes within the smallest spatial units.

[0107] The three - dimensional heat Figure 1 On the one hand, display the smallest spatial units with a large number of drainage or venting points in a dark color and the smallest spatial units with a small number of drainage or venting points in a light color; on the other hand, fill the optimal funnel positions within the smallest spatial units with a general funnel model.

[0108] Step (6): Merge the smallest spatial units according to the set rules to obtain the globally optimized positions for funnel installation.

[0109] In actual engineering, it can often be further optimized so that multiple minimum space units correspond to a globally optimal position of the funnel and a globally sub-optimal position of the funnel. Therefore, in this embodiment, the minimum space units are merged according to the set rules to obtain a globally optimized scheme for the funnel installation position.

[0110] 1) As an implementation method, a grouping and screening method with the minimum space unit as the seeded player is adopted, which specifically includes the following process:

[0111] ① Sort the minimum space units according to the number of interfaces of the hydrophobic pipeline, the drain pipeline, and / or the vent pipeline in each minimum space unit from more to less; select the top K minimum space units with more interfaces as the seed units, and the remaining minimum space units as non-seed units; where K is a set integer value.

[0112] ② Each seed unit forms a group. For the non-seed units on the same floor as the seed unit, divide them into the corresponding groups according to the principle of the smallest weighted nominal distance from the seed unit, and obtain K group space units;

[0113] Among them, the weighted nominal distance refers to: the product of the average distance between the funnel installation position of the non-seed unit and the funnel installation position of the seed unit and the number of interfaces of the non-seed unit;

[0114] Among them, the average distance between the funnel installation position of the non-seed unit and the funnel installation position of the seed unit is specifically:

[0115] The average of the distance between the locally optimal position of the funnel of the non-seed unit and the locally optimal position of the funnel of the seed unit, the distance between the locally optimal position of the funnel of the non-seed unit and the locally sub-optimal position of the funnel of the seed unit, the distance between the locally sub-optimal position of the funnel of the non-seed unit and the locally optimal position of the funnel of the seed unit, and the distance between the locally sub-optimal position of the funnel of the non-seed unit and the locally sub-optimal position of the funnel of the seed unit.

[0116] It should be noted that the above distance refers to the direct connection distance between two points, which is specifically represented by the magnitude of the vector.

[0117] For example: taking the coordinate of the locally optimal position of the funnel installation of the non-seed unit as the starting point and the coordinate of the locally optimal position of the funnel installation of the seed unit as the end point, establish a vector and obtain the magnitude A1 of the vector;

[0118] Taking the coordinate of the locally optimal position of the funnel installation of the non-seed unit as the starting point and the coordinate of the locally sub-optimal position of the funnel installation of the seed unit as the end point, establish a vector and obtain the magnitude A2 of the vector;

[0119] Taking the local sub-optimal position coordinates of the non-seed unit funnel installation as the starting point and the local optimal position coordinates of the seed unit funnel installation as the ending point, establish a vector and obtain the magnitude A3 of the vector;

[0120] Taking the local sub-optimal position coordinates of the non-seed unit funnel installation as the starting point and the local sub-optimal position coordinates of the seed unit funnel installation as the ending point, establish a vector and obtain the magnitude A4 of the vector;

[0121] Take the arithmetic mean of A1, A2, A3, and A4, and the product of this mean and the number L of interfaces of the corresponding drain pipe or vent pipe in the non-seed unit is the weighted nominal distance Q between the non-seed unit and the seed unit.

[0122] As a preferred embodiment, determine several nearest seed units on the same floor as the non-seed unit according to the unit geometric distance; wherein, the unit geometric distance refers to the distance J between the geometric centers of two smallest spatial units; among them, the geometric center is an inherent geometric property of the spatial unit and has nothing to do with the layout density and layout position of the drain points and vent points. At this time, only calculate the weighted nominal distance between the non-seed unit and the nearest seed units, and there is no need to calculate for each seed unit, which reduces the amount of calculation and improves the calculation efficiency.

[0123] Add the non-seed unit to the group where the seed unit with the smallest weighted nominal distance is located, and group all non-seed units one by one according to this method; the seed units and non-seed units in each group constitute the merged group spatial unit.

[0124] ③ For each group spatial unit, determine the potential funnel installation positions on the column; with the goal of minimizing the total pipe weight of all drain pipes, water discharge pipes, and / or vent pipes reaching a certain potential funnel installation position, determine the global optimal position and sub-optimal position of the funnel installation position within each corresponding group spatial unit.

[0125] In the merged group spatial unit, select the local optimal position or sub-optimal position of the seed unit funnel installation, and the local optimal position or sub-optimal position of the funnel installation of the non-seed smallest spatial unit with the largest number of interfaces of the drain pipe or vent pipe as the potential funnel installation positions of the group spatial unit.

[0126] In this embodiment, the total pipe weight is the sum of the pipe weights of all drain pipes, water discharge pipes, and / or vent pipes, and the pipe weight of a single pipe is the product of the per-meter pipe unit weight corresponding to the pipe diameter and the pipe length. The pipe length uses the polyline distance, that is, the sum of the absolute values of the differences in the x-axis, y-axis, and z-axis coordinates of the starting point and the ending point.

[0127] Based on the above potential funnel installation positions, sort the potential funnel installation positions according to the total weight of all drain pipes or vent pipes within the calculated group space unit; the funnel installation position corresponding to the minimum total pipe weight is used as the globally optimal position for funnel installation within the group space unit, and the funnel installation position corresponding to the second smallest total pipe weight is used as the globally sub-optimal position for funnel installation within the group space unit.

[0128] 2) As another implementation manner, a grouping and screening and advancing method with columns as seeded players is adopted, and the specific process includes the following:

[0129] ① Count the sum of the interfaces of the drain pipes, drain pipes, and / or vent pipes corresponding to the funnels at the locally optimal or sub-optimal positions on each column; among them, the sum of the number of drain points, drain points, and vent points within a minimum space unit is equal to the sum of the interfaces of the drain pipes, drain pipes, and / or vent pipes corresponding to the funnel at the locally optimal position within this minimum space unit, and is also equal to the sum of the interfaces of the drain pipes, drain pipes, and / or vent pipes corresponding to the funnel at the locally sub-optimal position within this minimum space unit; when the locally optimal position and the locally sub-optimal position of the funnel within the same minimum space unit are on different sides of the same column, only one of the funnels is selected for counting.

[0130] In this embodiment, each column has four sides, corresponding to four minimum space units, where two adjacent sides of the column correspond to one minimum space unit; count the sum of the interfaces of all the drain pipes, drain pipes, and / or vent pipes in the corresponding minimum space units at the locally optimal position or the locally sub-optimal position of the funnel installation on each column, and sort the columns in descending order according to the sum of the quantities;

[0131] For example: if a side corresponding to the first minimum space unit on a certain column has a locally optimal position or a locally sub-optimal position, the funnel at this position is connected to all the drain pipes, drain pipes, and / or vent pipes within this minimum space unit, and count the sum of the quantities B1 of all the pipe interfaces;

[0132] If the side corresponding to the first minimum space unit on this column simultaneously has a locally optimal position and a locally sub-optimal position, the sum of the corresponding pipe interfaces of this column is still B1;

[0133] If the side corresponding to the second minimum space unit on this column also has a locally optimal position or a locally sub-optimal position, the sum of the corresponding pipe interfaces of this column is B1 + B2, where B2 is the sum of the interfaces of all the drain pipes, drain pipes, and / or vent pipes within the second minimum space unit.

[0134] ② Select the top P columns with a larger number of the said interfaces as seed columns; where P is a set integer value; centered on the seed columns, merge the minimum space units according to a set rule. For example: select to merge in a "day" shape, "field" shape, or "nine-square grid" manner according to the heat map generated in step (5) to obtain merged space units; or, perform a custom space combination by manually checking the minimum space units to achieve space merging.

[0135] ③ For each merged space unit, determine the potential funnel installation positions on the columns; with the goal of minimizing the total pipe weight of all drain pipes, drain water pipes, and / or air vent pipes reaching a certain potential funnel installation position, determine the globally optimal position and the sub-optimal position of the funnel installation position within each corresponding small space unit.

[0136] Specifically, use the locally optimal position or the sub-optimal position of the funnel installation on the seed columns as the potential funnel installation positions in the merged space units.

[0137] Based on the above potential funnel installation positions, sort the potential funnel installation positions according to the calculated total pipe weight of all drain and water pipes or air vent pipes within the merged space unit; the funnel installation position corresponding to the minimum total pipe weight is used as the globally optimal position of the funnel installation within the merged space unit, and the funnel installation position corresponding to the second smallest total pipe weight is used as the globally sub-optimal position of the funnel installation within the merged space unit.

[0138] Compared with Embodiment 1), Embodiment 2) allows the designer to perform manual intervention during the merging process, enhancing the human-computer interaction during the merging process and facilitating the handling of complex adaptability problems.

[0139] As a preferred embodiment, first perform forward automatic design using Embodiment 1), and then perform reverse verification using Embodiment 2). Necessary manual intervention can be carried out during the key link of space merging in the reverse verification.

[0140] Step (7): Based on the general funnel model, input the number of interfaces of the funnel (i.e., the interfaces of the drain pipes and air vent pipes connected to the funnel) according to the number of drain and water points or air vent points as the personalized configuration of the actual funnel, and generate the three-dimensional model of the funnel.

[0141] Step (8): Based on the funnel installation position determined in step (4) or step (6), perform an adaptability check on the surrounding environment, equipment, and pipelines, including rechecking collisions, safety distances, etc. For example, when it is not suitable to install a funnel next to the electrical control cabinet, abandon the first recommended position and then perform an adaptability check on the second recommended position, and so on until the adaptability check is passed and the final funnel position is finally selected. Then import the 3D model of the funnel generated in step (7) into the overall design model of the factory according to the final funnel position.

[0142] Step (9): Based on the funnel installation position, determine the length of the drain and vent pipelines, and then multiply it by a margin coefficient to obtain the material quantity of the pipelines, which is convenient for the construction unit to purchase according to needs; where the margin coefficient is a set value.
