Description

Technical Field

[0001] This invention relates to the field of BIM model design technology, specifically to a method, equipment, and storage medium for intelligent prefabrication detailed design of BIM models. Background Technology

[0002] Currently, the construction industry is characterized by extensive production methods, requiring individual design for each building, resulting in unique structures and electromechanical components. This demand for personalization presents a significant challenge to the construction industry's transformation towards a new type of industrialization.

[0003] In the field of building electromechanical systems, the processing and production of prefabricated components are characterized by small batches, multiple production runs, high non-standardization, and customization. These prefabricated components vary greatly in size, shape, type, and quantity. Currently, the typical application scenario for industrialized building electromechanical installation is the fully prefabricated assembly room, which presents the following design challenges.

[0004] 1. The lack of industry standard requirements for the basic design data of the BIM model at the design source means that the basic design data calculated from the BIM model cannot guide production and processing management.

[0005] 2. Currently, the electromechanical industry typically uses traditional BIM design and detailing software, which generally suffers from low levels of intelligence, long manual design cycles, and low work efficiency, making it difficult to achieve efficient, high-precision prefabrication detailing at the industrial level.

[0006] 3. The lack of industry standards and guidance at the source of BIM design leads to the unlimited non-standardization of prefabricated products, making it difficult to meet the needs of industrialized, digitalized, and efficient production.

[0007] 4. BIM models are closed at the design stage, and data is disconnected from the production stage and subsequent stages. They rely entirely on manual, inefficient analysis and transfer, which cannot meet the requirements of industrialization and hinders the implementation of BIM models from start to finish. Summary of the Invention

[0008] This invention proposes a BIM model intelligent prefabrication detailed design method, equipment and storage medium, which solves problems such as low intelligence level of design software, unlimited non-standardization of design results and design data not meeting the requirements of industrial processing.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A BIM model-based intelligent prefabrication detailed design method includes the following steps:

[0011] S1. Design a refined and standardized governance algorithm for basic design data of electromechanical models;

[0012] S2. Based on step S1, design a rapid prefabrication detailed design algorithm.

[0013] Furthermore, step S1 specifically includes:

[0014] S11. Establish a standard-specific design family library for computer rooms, covering two categories: computer room piping connection family library and computer room piping valve family library. The key design parameters for computer room piping connection parts are set according to national standard specifications and drawings, while the key design parameters for computer room valve family library are set according to the requirements affecting processing and production.

[0015] S12. Review the key design parameters of the original design drawings and design specifications of the computer room pipelines, and organize the key design parameter information of the materials used for different pipe diameters of prefabricated pipes in the computer room and their corresponding connection methods, as well as the outer diameter and wall thickness of the pipes corresponding to the nominal diameter of the pipes under various materials.

[0016] S13. Input the design parameters of pipe outer diameter and wall thickness corresponding to the nominal diameter of pipes for various materials into the Revit design software;

[0017] S14. In Revit design software, use the information setting function to parameterize the materials and corresponding connection methods used for different pipe diameters of prefabricated pipes. At the same time, retrieve the parameter information in S12 to realize the basic design information setting of the model, export the design information list, and clear the original incorrect basic design information.

[0018] S15. Using the pipe type replacement function, import the design information list, identify the basic settings of the pipe type parameters in the original BIM model, match them with the parameter settings in the design list, retrieve the standard pipe section types and connectors in the design list, and replace the model.

[0019] S16. Using the valve accessory replacement function, extract the valve connection family model in the original design model. By setting keywords, realize the intelligent matching of the valve family parts in the original model with the special valve family library of the computer room pipeline. Using the replacement function, replace the valve family in the original design model to generate a standard valve family with special prefabricated design parameters.

[0020] S17. Using the valve accessory size parameter adjustment function, extract the key design parameters that affect prefabrication production and processing from the valve family model that carries special prefabrication design parameters after replacement, and import them in batches according to the actual measurement data of engineering procurement, so as to realize the one-to-one restoration of BIM model design data and improve the work efficiency of writing design model data.

[0021] S18. By using the above standard family library, design information settings, two identification and replacement functions, and one parameterized batch adjustment function, the original electromechanical BIM model transferred by the design institute can be replaced with a standard BIM family model, and the original design basic model data and procurement basic design data can be quickly imported, ultimately achieving standardized governance of BIM model design data.

[0022] Further, step S2 includes,

[0023] S21. Based on national standards, a standard BIM family model of flanges and bolts commonly used in computer rooms under different pressures was established. In the BIM model, the theoretical parameter data of the national standard is used as the basic model design data. After the flange materials of the project arrive on site, the accurate design data is accurately re-measured to determine the final measured design parameters. Through the table import and export function, the accurate design data can be brought into the BIM model.

[0024] S22. Based on the requirements of industrialized prefabrication of air conditioning water pipes and the connection method of balanced flanges and pipes, the key basic design parameter setting of pipe insertion depth into flat welding flanges was introduced. The distance parameter of pipe insertion into flange under different pipe diameters was set, so as to achieve consistency between the pipe design process based on BIM model and the process parameters of production line processing, cutting and assembly.

[0025] S23. Formulate design principles for the connection of piping and commonly used valves in the fully prefabricated machine room, as the basis for the automatic generation design of rapid prefabricated segmented flanges at the valve locations in the fully prefabricated machine room.

[0026] S24. To address the issue of unlimited non-standardization of prefabricated pipe sections in data centers due to the lack of component-level standard constraints during the detailed design stage, the industry's first design process standard library for prefabricated pipe sections in data centers has been established, comprising 5 major categories (I, L, F, T, and Z) and 65 sub-items. Standardization rules have been defined for prefabricated pipe sections based on parameters such as product type, assembly form, and geometric dimensions. This transforms the unlimited non-standardized pipe sections into standard products that can be parameterized, providing a product standard basis for the detailed design of digital prefabricated data centers.

[0027] By standardizing the design parameter codes for various design parameters such as pipe outer diameter, wall thickness, length, flange thickness, depth, elbow outer diameter, and center radius, a standard library of design process data is formed.

[0028] S25. Based on the design process standard library of 4 major categories and 65 sub-items of prefabricated pipe sections for computer room, reverse-engineer the design flange generation principle for prefabricated segmented design of fully prefabricated computer room pipes, and formulate relevant prefabricated products as the basis for the generation design of segmented pipe connections.

[0029] S26. Based on the types of prefabricated pipes in the fully prefabricated machine room and the connection relationship between the main and branch pipes, the automatic segmentation priority design principle for industrialized products of electromechanical installation was formulated as the design mechanism for the sequential generation of flanges for the rapid prefabrication and segmentation design of all pipes and valve components in the machine room.

[0030] S27. Extract the segmented range of the fully prefabricated computer room pipeline in the BIM model. According to the design scenario, extract the pipeline item by item in batches according to the whole connecting pipeline, or extract it in batches according to similar systems. Combined with the automatic segmentation algorithm of computer room pipeline and the two flange generation design principles, the automatic generation of flange connection parts of the computer room electromechanical pipeline BIM model can be realized.

[0031] S28. Establish product numbering principles. Based on the principle that each piping system independently identifies all connected pipes, connectors and their corresponding flanges in the machine room, the product numbering algorithm will number all selected components starting from the equipment port, first numbering branch pipes and then main pipes, and freely combining them. It will match the design process standard library of prefabricated pipe sections in the machine room. After successful matching, the automatic software will start the grouping function to form each prefabricated product, and assign product numbers and write product information data into the new BIM model attributes.

[0032] S29. Extract the model of each prefabricated product with a number, develop the function of automatically generating processing drawings for prefabricated products, automatically generate front view, side view, top view and three-dimensional view for each prefabricated product, and automatically generate design information statistics and writing such as design annotations, production instructions, drawing frames and drawing names, and key design statistics tables according to production and processing requirements.

[0033] S210. First, set the cutting parameters for the pipe material. The cutting length parameter is set according to the material loss length after cutting by the factory cutting machine, and the raw material cutting length parameter is the length of the pipe raw material purchased.

[0034] S211. Establish an intelligent material placement algorithm for prefabricated pipe products in the computer room, extract the design data of the processed pipe sections in the prefabricated products in the model, and reasonably summarize the number and sub-number of each processed product according to the loss of pipe raw materials and cutting length parameters. In the raw materials, perform BOM-driven data statistics on the cutting sequence and key cutting process parameters, and export the BOM list to the factory for cutting to realize model data driving.

[0035] S212. Utilize the intelligent compilation and statistical function of the prefabricated pipeline product model data in the computer room to formulate a standard model-driven statistical data BOM list around the material procurement, AGV automatic material picking and preparation, product quality inspection, and product on-site delivery. Use the intelligent compilation and statistical function to extract and compile model design data.

[0036] Furthermore, the design principles for the connection of piping and commonly used valves in the fully prefabricated machine room in step S23 are as follows:

[0037] a. The pipes on both sides of the reducer or reducer are connected using butterfly valve flanges;

[0038] b. The pipes on both sides of the wafer-type butterfly valve and the flange-type butterfly valve are connected by butterfly valve flanges.

[0039] c. Flat-welded flanges are used to connect the pipe sections.

[0040] d. The piping on both sides of the Y-type filter, check valve, energy meter, and balancing valve is connected by flat-welded flanges;

[0041] e. The flanges connecting the equipment are generally connected using the flanges that come with the equipment itself.

[0042] Furthermore, the flange generation design principles in step S25 are as follows:

[0043] a. Main pipe prefabrication segmented design principle: The flanges at the main pipe locations are automatically generated according to the following product length parameters;

[0044] b. Main and branch pipe prefabricated segmented design principle: The flanges at the main pipe positions are automatically generated according to the distance between the outer wall of the branch pipe and the main pipe.

[0045] c. Intersecting line branch pipe prefabrication segmented design principle: The flanges at the branch pipe positions are automatically generated according to the length parameters of T-class and F-class products.

[0046] d. Branch pipe segment design principle: For type I and type L products, flanges are intelligently generated based on length parameters.

[0047] Furthermore, the automatic segmentation priority design principle in step S26 is as follows:

[0048] Priority 1: Main pipe bends, main and branch pipe connections, and branch pipes.

[0049] Priority 2: Main elbows and intersecting lines;

[0050] Priority 3: Main product for direct pipeline section, serving as a segmented connection.

[0051] Furthermore, the algorithm calculation principles in S211 are as follows:

[0052] (1) Global cloth distribution in the model:

[0053] a. This method is consistent with the original fabric format, and a fabric count is performed on all products for which designs have been produced;

[0054] b. Ignore the numbering order and calculate the material placement based on the method of minimizing the number of cuts and the amount of remaining pipe material consumed;

[0055] c. The length of a single finished pipe is ≥ ∑ (pipe length) + number of cuts * cutting loss.

[0056] (2) Product Number Fabric:

[0057] a) This method uses the product numbers in ascending order to select fabric. One fabric data contains n complete or adjacent products.

[0058] b. While maintaining the product number in ascending order, use the method of cutting the least and consuming the least amount of remaining pipe material for material placement;

[0059] c. If, after a product is finished, there is leftover material that can be used for some of the pipes in adjacent numbered products, the pipes in the adjacent numbered products can be included in the fabric. The adjacent numbers are also fabricated in ascending order.

[0060] d. The length of a single finished pipe is ≥ ∑ (the length of the pipe in a single product) + ∑ (the length of the pipe in adjacent numbered products) + the number of cuts * cutting loss.

[0061] (3) Production line fabrication in stages and batches:

[0062] a. This method filters pipelines by production line, production period, and batch, and then distributes materials according to the ascending product number.

[0063] b. First, screen the pipes from the same production line and batch;

[0064] c. In the case of the same production line and the same batch, ignore the numbering order and calculate the material layout based on the method of cutting the least and having the least amount of remaining pipe material consumed.

[0065] d. The length of a single finished pipe is ≥ ∑ (the length of pipes in the same product period and batch) + the number of cuts * cutting loss.

[0066] (4) Fabrics produced in phases and batches with adjacent serial numbers on the production line:

[0067] a. This method involves screening the pipelines based on production line, production period, and batch, and then placing the materials according to the product's adjacent number.

[0068] b. First, select pipes from the same production line and batch; while maintaining the product number in ascending order, use the method of cutting the least and consuming the least amount of remaining pipe material for material placement.

[0069] c. If, after a product is finished, there is leftover material that can be used for some of the pipes in adjacent numbered products, the pipes in the adjacent numbered products can be included in the fabric. The adjacent numbers are also fabricated in ascending order.

[0070] d. The length of a single finished pipe is ≥ ∑ (the length of pipes in a single product of the same production line and batch) + ∑ (the length of pipes in adjacent numbered products of the same production line and batch) + number of cuts * cutting loss

[0071] In another aspect, the present invention also discloses a computer-readable storage medium storing a computer program, which, when executed by a processor, causes the processor to perform the steps of the method described above.

[0072] In another aspect, the present invention also discloses a computer device, including a memory and a processor, wherein the memory stores a computer program, and when the computer program is executed by the processor, the processor performs the steps of the method described above.

[0073] This invention solves the problem of the inability to industrialize and digitize prefabricated pipe sections due to the lack of standardization of prefabricated components, transforming nearly 100% non-standard products into standardized products. By creating a series of modular prefabricated machine room products, on-site assembly and construction achieves green and safe construction without welding or cutting, and with a modular approach, improving installation efficiency by more than 70% compared to traditional methods.

[0074] It can solve current industry problems:

[0075] This technological achievement solves the problems of low efficiency in traditional manual prefabrication decomposition design based on BIM / CAD, low utilization rate of BIM design data when design information is transferred through two-dimensional drawings, lack of processing technology information in the design model, and high non-standard rate of traditional prefabricated product design.

[0076] This technology has been applied to the construction of the Shenzhen China Construction Greater Bay Area Smart Industrial Park and has been promoted and applied in eight other construction projects, including the Shenzhen Liuxiandong Strategic Emerging Industries Headquarters Base and the Zhuhai Hengqin Science City Phase II. This has significantly improved my country's industrialized intelligent manufacturing technology in the construction electromechanical sector, achieving substantial social and economic benefits. According to evaluations by Academician Ding Lieyun and other industry professionals, this technology has reached an internationally leading level in the construction industry as a whole.

[0077] Figure 1 This is a flowchart of the present invention. Detailed Implementation

[0078] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0079] like Figure 1 As shown in this embodiment, the intelligent prefabrication detailed design method for BIM models includes the following steps:

[0080] 1. A refined and standardized governance algorithm for basic design data of electromechanical models was developed.

[0081] Step 1: Establish a standard-specific design family library for computer rooms, covering two categories: computer room piping connection family library and computer room piping valve family library. The key design parameters for computer room piping connection family library are set according to the national standard specification atlas (XXX), while the key design parameters for computer room valve family library are set according to the requirements affecting processing and production.

[0082] Step 2: Review the original design drawings and design specifications for the computer room pipelines, and compile information on the materials used for different pipe diameters of prefabricated pipes in the computer room, their corresponding connection methods, and the key design parameters of the pipe outer diameter and wall thickness corresponding to the nominal diameter of the pipes for each material.

[0083] Step 3: Input the design parameters of pipe outer diameter and wall thickness corresponding to the nominal diameter of pipes for various materials into the Revit design software.

[0084] Step 4: In Revit design software, use the information settings function to parameterize the materials and corresponding connection methods used for different pipe diameters of prefabricated pipes. Simultaneously, retrieve the parameter information from Step 2 to complete the basic design information settings for the model, export the design information list, and clear any erroneous basic design information. (Highlight of this technology: This setting allows for standardized setting of original design information parameters, and the exported list can clear non-standard design information from the original design institute's BIM model, improving the accuracy of the model's basic design parameters.)

[0085] Step 5: Using the pipe type replacement function, import the design information list, identify the basic settings of pipe type parameters in the original BIM model, match them with the parameter settings in the design list, retrieve the standard pipe section types and connectors from the design list, and replace the model. (Highlight of this technology: by identifying the standard design basic information list and standard pipes)

[0086] Step Six: Utilize the valve accessory replacement function to extract the valve connection family model from the original design model. By setting keywords, intelligently match the valve family components in the original model with the specialized valve family library for computer room piping. Then, use the replacement function to replace the valve families in the original design model, generating standard valve families carrying specialized pre-design parameters. (Highlight of this technology: By setting keywords, the original design valves in the model are quickly matched and replaced with valves in the specialized valve family library, achieving efficient utilization of valves in the original design model and improving model data management efficiency.)

[0087] Step 7: Utilize the valve accessory size parameter adjustment function to extract key design parameters affecting prefabrication and manufacturing from the replaced standard valve family model that carries specific prefabrication design parameters. Then, batch import these parameters based on actual measurement data from the engineering procurement process, achieving a one-to-one restoration of the BIM model design data and improving the efficiency of writing design model data. (Highlight of this technology: By setting key design parameters in the dedicated line family and combining them with the batch adjustment function, the design parameters of the replaced BIM model can be quickly adjusted, improving the efficiency of writing BIM model design parameters.)

[0088] Step 8: By using the above standard family library, design information settings, two identification and replacement functions, and one parameterized batch adjustment function, the original electromechanical BIM model transferred by the design institute can be replaced with a standard BIM family model. The original design basic model data and procurement basic design data can be quickly imported, ultimately achieving standardized governance of BIM model design data.

[0089] 2. Rapid prefabrication detailed design technology was developed.

[0090] Step 1: Based on the national standard GB / T 9124.1-2019 "Steel Pipe Flanges Part 1: PN Series", a standard BIM family model of flanges and bolts commonly used in computer rooms under different pressures was established. In the BIM model, the theoretical parameter data of the national standard is used as the basic model design data. After the flange materials for the project arrive on site, the accurate design data is accurately measured to determine the final measured design parameters. Through the table import and export function, the accurate design data can be brought into the BIM model to ensure the accuracy of the basic design of the BIM model.

[0091] Step 2: Based on the requirements for industrial prefabrication of air conditioning water pipes and the connection method between the balance flange and the pipe, key basic design parameters for the depth of pipe insertion into the flat welding flange were introduced. The distance parameters for pipe insertion into the flange under different pipe diameters were set, which ensured that the pipe design process based on the BIM model was consistent with the process parameters of material cutting and assembly on the production line, thereby improving the accuracy of the BIM model design data.

[0092] Step 3: Develop design principles for the connection of piping and commonly used valves in the fully prefabricated machine room, serving as the basis for the automated generation design of rapidly prefabricated segmented flanges at valve locations. The design principles for the connection of piping and commonly used valves in the fully prefabricated machine room are as follows:

[0093] a. The pipes on both sides of the reducer or reducer are connected using butterfly valve flanges;

[0094] b. The pipes on both sides of the wafer-type butterfly valve and the flange-type butterfly valve are connected by butterfly valve flanges.

[0095] c. Flat-welded flanges are used to connect the pipe sections.

[0096] d. The piping on both sides of the Y-type filter, check valve, energy meter, and balancing valve is connected by flat-welded flanges;

[0097] e. The flanges connecting the equipment are generally connected using the flanges that come with the equipment itself.

[0098] Step Four: Addressing the issue of unlimited non-standardization in prefabricated pipe sections for data centers due to the lack of component-level standards during the detailed design phase, this study established the industry's first design process standard library for prefabricated pipe sections for data centers, comprising 5 major categories (I, L, F, T, and Z) and 65 sub-items. Standardization rules were defined for prefabricated pipe sections based on product type, assembly form, and dimensional parameters, transforming the unlimited non-standardization of pipe sections into parameterizable standard products, providing a product standard foundation for the detailed design of digital prefabricated data centers. By standardizing the codes for various design parameters such as pipe outer diameter, wall thickness, length, flange thickness, depth, elbow outer diameter, and center radius, a design process data standard library was formed.

[0099] Step 5: Based on the design process standard library of 4 major categories and 65 sub-items of prefabricated piping components for the computer room, reverse-engineer the flange generation principles for the prefabricated segmented design of the fully prefabricated computer room piping, and formulate relevant prefabricated components as the basis for the segmented connection generation design of the piping. The flange generation design principles are as follows:

[0100] a. Main pipe pre-made segmented design principle: The flanges at the main pipe positions are automatically generated according to the following product length parameters.

[0101] b. Main and branch pipe prefabricated segmented design principle: The flanges at the main pipe positions are automatically generated according to the distance between the outer wall of the branch pipe and the main pipe.

[0102] c. Intersecting line branch pipe prefabrication segmented design principle: The flanges at the branch pipe locations are automatically generated according to the length parameters of T-class and F-class products.

[0103] d. Branch pipe segment design principle: For type I and type L products, flanges are intelligently generated based on length parameters.

[0104] Step Six: Based on the types of prefabricated piping in the fully prefabricated machine room and the connection relationships between main and branch pipes, an automatic segmentation priority design principle for industrialized electromechanical installation products was established. This principle serves as the design mechanism for the sequential generation of flanges in the rapid prefabrication and segmentation design of all piping and valve components in the machine room. The automatic segmentation priority design principle is as follows:

[0105] Priority 1: Main pipe bends, main and branch pipe connections, and branch pipes.

[0106] Priority 2: Main elbows and intersecting lines;

[0107] Priority 3: Main product for direct pipeline section, serving as a segmented connection.

[0108] Step 7: Extract segmented ranges of the prefabricated equipment room piping from the BIM model. Depending on the design scenario, extraction can be performed item by item along the entire connecting pipe section, or in batches based on similar systems. Combining the automatic segmentation algorithm for equipment room piping with two flange generation design principles, the automatic generation of flange connections for the equipment room's electromechanical pipelines in the BIM model can be achieved. (This technology's highlight: By setting rules such as a 4-category, 65-item design process standard library for prefabricated equipment room pipe sections, key product parameter setting principles, and main and branch pipeline segmentation design priorities, the algorithm transforms the traditional non-standardized segmented design of prefabricated equipment room piping into a standardized prefabricated design. This improves design standardization at the design source, thereby driving batch processing and production.)

[0109] Step 8: Establish product numbering principles. For each piping system, independently identify all connected pipes, connectors, and corresponding flanges within the machine room. The product numbering algorithm will number all selected components starting from the equipment outlet, first numbering branch pipes, then main pipes, allowing for free combination. This is matched against the machine room's prefabricated pipe section design process standard library. Upon successful matching, the automatic software grouping function is activated, forming each prefabricated product and assigning it a product number. The product name is set as (system abbreviation XXX-01 / N). The number increments according to the system's product quantity. Product information data is then written into the newly added BIM model attributes. (This technical highlight: Through the free product grouping algorithm and the automatic numbering parameter writing algorithm, productized design of building mechanical and electrical piping can be achieved.)

[0110] Step Nine: Extract the prefabricated product model for each number and develop a function to automatically generate processing drawings for the prefabricated products. This function automatically generates front, side, top, and 3D views for each prefabricated product. Simultaneously, it automatically generates design annotations, production instructions, drawing frames and titles, key design statistics tables, and other design information statistics according to production and processing requirements. (Highlight of this technology: The automatic product drawing generation function enables standardized drawing generation for each product, improving design drawing efficiency by over 95%).

[0111] Step 10: First, set the cutting parameters for the pipe material. The cutting length parameter is set according to the material loss length after cutting by the factory cutting machine, and the raw material cutting length parameter is the length of the pipe raw material purchased, which is usually 12m / 6m by default.

[0112] Step 11: Establish an intelligent material placement algorithm for prefabricated piping products in the computer room. Extract design data of processed pipe sections from the prefabricated products in the model. Based on the material loss of pipe raw materials and cutting length parameters, rationally summarize the product number and sub-number for each processed product. In the raw materials, perform BOM-driven data statistics on the cutting sequence and key cutting process parameters, and export the BOM list for factory cutting to achieve model data-driven operation. (Highlights of this intelligent material placement algorithm for prefabricated piping products in the computer room: Through intelligent material placement statistics, it is possible to effectively plan the processing cycle, cutting process, and cutting procedures required for the prefabricated products of the project, and export relevant driving BOM data, which can drive plasma cutting, automatic rust removal machines, and automatic material feeding warehouses for automated production of material feeding, rust removal, and cutting.) The algorithm calculation principles are as follows:

[0113] (1) Global cloth distribution in the model:

[0114] a. This method is consistent with the original fabric format, and a fabric count is performed on all products for which designs have been produced;

[0115] b. Ignore the numbering order and calculate the material placement based on the method of minimizing the number of cuts and the amount of remaining pipe material consumed;

[0116] c. The length of a single finished pipe is ≥ ∑ (pipe length) + number of cuts * cutting loss.

[0117] (2) Product Number Fabric:

[0118] a) This method uses the product numbers in ascending order to select fabric. One fabric data contains n complete or adjacent products.

[0119] b. While maintaining the product number in ascending order, use the method of cutting the least and consuming the least amount of remaining pipe material for material placement;

[0120] c. If, after a product is finished, there is leftover material that can be used for some of the pipes in adjacent numbered products, the pipes in the adjacent numbered products can be included in the fabric. The adjacent numbers are also fabricated in ascending order.

[0121] d. The length of a single finished pipe is ≥ ∑ (the length of the pipe in a single product) + ∑ (the length of the pipe in adjacent numbered products) + the number of cuts * cutting loss.

[0122] (3) Production line fabrication in stages and batches:

[0123] a. This method filters pipelines by production line, production period, and batch, and then distributes materials according to the ascending product number.

[0124] b. First, screen the pipes from the same production line and batch;

[0125] c. In the case of the same production line and the same batch, ignore the numbering order and calculate the material layout based on the method of cutting the least and having the least amount of remaining pipe material consumed.

[0126] d. The length of a single finished pipe is ≥ ∑ (the length of pipes in the same product period and batch) + the number of cuts * cutting loss.

[0127] (4) Fabrics produced in phases and batches with adjacent serial numbers on the production line:

[0128] a. This method involves screening the pipelines based on production line, production period, and batch, and then placing the materials according to the product's adjacent number.

[0129] b. First, select pipes from the same production line and batch; while maintaining the product number in ascending order, use the method of cutting the least and consuming the least amount of remaining pipe material for material placement.

[0130] c. If, after a product is finished, there is leftover material that can be used for some of the pipes in adjacent numbered products, the pipes in the adjacent numbered products can be included in the fabric. The adjacent numbers are also fabricated in ascending order.

[0131] d. The length of a single finished pipe is ≥ ∑ (the length of pipe in a single product of the same production line and batch) + ∑ (the length of pipe in adjacent numbered products of the same production line and batch) + number of cuts * cutting loss.

[0132] Step 12: Utilize the intelligent statistical compilation function of the prefabricated pipeline product model data in the computer room to formulate a standard model-driven statistical data BOM list around the material procurement, AGV automatic material picking and preparation, product quality inspection, and product on-site delivery. Use the intelligent statistical compilation function to extract and compile model design data.
