Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment manufacturing, and in particular to a parameterized data modeling design method and system for a bus duct production process. Background Art

[0002] In the field of traditional bus duct production, enterprises have always adopted a static management model to carry out product production process design. Whenever they encounter bus duct products of different models, specifications, dimensions, or quantities, technicians need to statically design product process drawings one by one and compile a material list. In specific operations, technicians will use Autocad software to draw process drawings, and the key parts dimensions and material dimensions in the drawings must be calculated manually according to product technical specifications.

[0003] The disadvantages of this traditional approach are very obvious. As long as any of the key parameters such as the rated current, size, and quantity of the product changes, the corresponding dimensional data must be manually recalculated. As a result, the design work is highly repetitive, and the technicians spend a lot of energy on repeated calculations and repeated drawings. The overall work efficiency is seriously reduced, and the time spent from product design to production is greatly extended. Not only that, due to frequent manual calculations and repeated operations, the design error rate remains high, which brings many potential risks to the subsequent production links and greatly affects the efficiency and quality of bus duct product production.

[0004] Given that the traditional model is in deep trouble, an innovative production process design method is urgently needed to break the current deadlock and comprehensively improve the efficiency of bus duct production process design. Summary of the invention

[0005] In view of this, the purpose of the present invention is to overcome the technical problems of the prior art such as duplication of work, long time consumption, low work efficiency and high design error rate, and to propose a parametric data modeling design method and system for the bus duct production process.

[0006] Based on the above purpose, the present invention provides a parameterized data modeling design method for a bus duct production process, comprising: Establish a bus duct product library according to the product categories of bus duct; Constructing a parameterized model for each product unit in the bus duct product library; Establish a selection rule base based on the parametric models of each product unit under different bus duct product categories; The selection rule library is used to screen, filter and match the pre-generated bus duct product list to find a unique matching parameterized model from multiple parameterized models; Substitute various parameters in the bus duct product list into the matched parameterized model in the form of variable values ​​for calculation, and obtain the material list and process parameters of the bus duct product unit; Generate 2D engineering drawings of self-made parts based on the bill of materials and process parameters combined with the corresponding drawing model.

[0007] In one embodiment, constructing a parameterized model for each product unit in the bus duct product library includes: Build a bill of materials model for each product unit, using fixed or formula values ​​to describe the material quantities of component lines; Building a material model for forming objects in the bill of materials model, wherein the material model includes various characteristic attribute values, and the characteristic attribute values ​​of the material are divided into fixed values ​​and formula values; A drawing model is established based on the material model, and the drawing model includes a design drawing set and a design file.

[0008] In one embodiment, a selection rule base is established based on parameterized models of each product unit under different product categories of bus duct, including: Determine a screening condition type, wherein the screening condition type includes a fixed screening condition and a variable screening condition; Integrate fixed and variable screening conditions to establish a selection rule base; The established selection rule base is tested to detect whether it can match the correct parameterized model based on the input parameters. If so, it is determined to be the final selection rule base. If not, the screening conditions are optimized until the correct parameterized model can be matched based on the input parameters.

[0009] In one of the embodiments, the fixed screening conditions have built-in solidified logic, and the variable screening conditions are constructed by converting dynamically changing key parameters into a formula model.

[0010] In one embodiment, the selection rule library is used to screen and filter the pre-generated bus duct product list and perform matching calculations, including: Perform a preliminary screening of the bus duct product list based on the fixed screening conditions of the selection rule library; Enable variable filtering conditions to conduct secondary screening on the bus duct product list after the initial screening; Extract various product parameters on the bus duct product list after secondary screening, and perform matching calculation on the extracted product parameters; Verify and provide feedback on the matching calculation results.

[0011] In one embodiment, various parameters in the bus duct product list are substituted into the matched parameterized model in the form of variable values ​​for calculation, including: Identify the key parameters on the bus duct product list and organize the identified key parameters into a standardized format; Establish a mapping relationship between the sorted key parameters and the variables in the matched parameterized model; According to the mapping relationship, the key parameters are sequentially substituted into the matched parametric model for layer-by-layer calculation to obtain the bill of materials and process parameters of the bus duct product unit.

[0012] In one of the embodiments, after the two-dimensional engineering drawing of the self-made part is generated, the two-dimensional engineering drawing and its bill of materials and process parameters are stored in a project design database for unified scheduling and execution management.

[0013] Based on the same inventive concept, the present invention also proposes a parametric data modeling design system for a bus duct production process, comprising: A product classification module is used to establish a bus duct product library according to the product categories of the bus duct; A parameterized model building module, which is used to build a parameterized model for each product unit in the bus duct product library; A selection rule establishment module, which is used to establish a selection rule library based on the parameterized models of each product unit under different product categories of bus duct; A model matching module, which is used to use the selection rule library to screen and filter the pre-generated bus duct product list and perform matching calculations to find a unique matching parameterized model from multiple parameterized models; The parameter calculation module is used to substitute various parameters in the bus duct product list into the matched parameterized model in the form of variable values ​​for calculation, and obtain the bill of materials and process parameters of the bus duct product unit; The engineering drawing drawing module is used to generate two-dimensional engineering drawings of self-made parts based on the bill of materials and process parameters in combination with the corresponding drawing model.

[0014] Based on the same inventive concept, the present invention also proposes an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the program, the parametric data modeling and design method for the bus duct production process described in the above embodiment is implemented.

[0021] Reference Figure 1 As shown, an embodiment of the present invention provides a parameterized data modeling design method for a bus duct production process, comprising the following steps: Step S10, establishing a bus duct product library according to the product categories of the bus duct; Step S20: construct a parameterized model for each product unit in the bus duct product library; Step S30: establishing a selection rule library based on parameterized models of each product unit under different product categories of bus duct; Step S40: Filter and perform matching calculations on the pre-generated bus duct product list using the selection rule library to find a unique matching parameterized model from multiple parameterized models; Step S50: Substitute various parameters in the bus duct product list into the matched parameterized model in the form of variable values ​​for calculation, and obtain the bill of materials and process parameters of the bus duct product unit; Step S60: Generate a two-dimensional engineering drawing of the self-made part according to the bill of materials and process parameters in combination with the corresponding drawing model.

[0022] The present invention provides a parametric data modeling and design method for a bus duct production process, which unlocks the automated design capability of bus duct products of different categories, specifications, and quantities through parametric assignment, innovates the design process, and greatly reduces the design time and errors; and the generated drawings and lists can seamlessly connect the processing links, eliminate information conversion costs, and facilitate the process from design to production to be completed in one go, thereby comprehensively improving the overall operating efficiency.

[0023] Among them, in step S10, the bus duct product categories can be divided into intensive bus duct (XMS-E), fire-resistant bus duct (XMS-F) and resin cast bus duct (XMS-J), etc.; different bus ducts are composed of different bus product units, generally composed of starting bus units, straight-through bus units (with and without sockets), L-type vertical (horizontal) bent bus units, Z-type vertical (horizontal) offset bus units, T-type vertical (horizontal) three-way bus units, X-type vertical (horizontal) four-way units, variable capacity bus units, expansion bus units, terminal head units, terminal junction box units, plug-in box units and bus duct related accessories and fastening devices. As an example, the intensive bus duct (XMS-E) product library is shown in Table 1 below: Table 1

[0024] The above busbar product units include but are not limited to ST type straight-through units, LV / LH type vertical bend units, LL / LR type horizontal bend units, ZL / ZR type horizontal elbow units, ZV / ZH type vertical elbow units and ZLV / ZLH type combined units, and their structures are as follows: Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 as well as Fig.11 shown.

[0025] Among them, in step S20, if Figure 2 As shown, the method for constructing a parameterized model for each product unit in the bus duct product library includes the following steps: Step S21, construct a bill of materials model for each product unit, using fixed values ​​or formula values ​​to describe the material quantity of the component line; Step S22: Building a material model for forming objects in a bill of materials model, wherein the material model includes various characteristic attribute values, and the characteristic attribute values ​​of the material are divided into fixed values ​​and formula values; Step S23: establishing a drawing model based on the material model, wherein the drawing model includes a design drawing set and a design file.

[0026] As an example, the parametric model of the above-mentioned product unit mainly includes a bill of materials model (hereinafter referred to as a BOM model), a material model and a drawing model, wherein the BOM model is a BOM (Bill of Material) of the busbar product unit, which is a product structure data file that can be recognized by a computer. It describes the product hierarchical structure of the busbar unit in a data format, and uses a fixed value or a formula value to describe the material quantity of the component row. The fixed value indicates that under the current product structure, the demand for the number of components is fixed, such as the demand quantity of N rows of parts materials under the straight-through unit is always 1. The formula value indicates that under the current product structure, the demand for the number of components is variable, and the demand quantity of component materials may change when external parameters change. For example, the number of copper bar raw materials used for the PE / L1 / L2 / L3 / N row under the straight-through unit is related to the length X of the straight-through unit. When the length X changes, the amount of copper bar raw materials naturally changes. As an example, Table 2 is a parametric BOM model of the current level 400A of the straight-through unit (ST) under the dense bus duct (XMS-E) as shown in Table 2: Table 2

[0027] The above material model is used for objects in the component BOM model, mainly including the material code, material description, unit of measurement and characteristic attributes (such as material group, cutting size, forming size, etc.), where the value of the characteristic attribute is a fixed value or a formula value. The fixed value means that the attribute value of the current material is fixed and does not change, such as the unit of measurement of the copper busbar part is piece, and the material group is the copper busbar part; in addition, the attributes of materials such as purchased parts and standard self-made parts are also fixed values. The formula value means that the attribute value of the current material changes with the change of external parameters, such as the cutting size and forming size of the copper busbar part are related to the length X of the straight-through unit. As an example, the parameterized material model of the current level 400A of the straight-through unit (ST) under the dense bus duct (XMS-E) is shown in Table 3 below: Table 3

[0028] The above-mentioned drawing model is used to guide production to process parts. The drawing model is mainly divided into design drawings and design files. The design drawings are a collection of standard samples and instruction files compiled according to certain rules. They are used to guide production-related users to process parts or conduct quality inspections. The content and format are fixed. As an example, Fig.12It is a schematic diagram of the LL / LR type horizontal elbow copper busbar atlas model; the design file is used for the equipment to perform refined operations, such as the DXF format file of sheet metal parts, in which variable parameters are replaced by variables; when the equipment is produced, the corresponding required design file is automatically generated based on the current material-related design file model and the specific parameter variable values ​​given by the front-end design. As an example, Fig.13 This is a schematic diagram of the ST type straight-through side panel design file model.

[0029] The above parameters mainly include (1) E: electrical system category, optional values ​​are 45 (3L+N+aluminum PE) and 46 (3L+N+copper PE); (2) A: current level, optional values ​​are 400A, 500A, 630A, 800A, 1600A, 2000A, 3200A, 5000A, etc.; (3) G: copper busbar specification, optional values ​​are 4*30, 5*30, 6*30, 6*40, 3*50, 6*50, 6*60, etc.; (4) P: protection level, optional values ​​are IP54 and IP65, etc.; (5) S: spray color, optional values ​​are empty, RGB01, RGB02, RGB03, etc.; (6) X / Y / Z: length variable, the value is a number.

[0030] Among them, in step S30, if Figure 3 As shown, the method for establishing a selection rule base based on the parameterized model of each product unit under different product categories of bus duct includes the following steps: Step S31, determining the type of screening condition, wherein the screening condition type includes fixed screening conditions and variable screening conditions; Step S32, integrating fixed screening conditions and variable screening conditions to establish a selection rule base; Step S33, test the established selection rule library to detect whether it can match the correct parameterized model according to the input parameters. If so, determine it as the final selection rule library. If not, optimize the screening conditions until it can match the correct parameterized model according to the input parameters.

[0031] Specifically, the fixed screening conditions mentioned above have built-in fixed logic to exclude parameterized models that fundamentally do not meet the established standards. Variable screening conditions are constructed by converting dynamically changing key parameters into formula models. In order for the computer system to accurately screen, such conditions need to be converted into formula models for calculation. The example gives two conversion situations: (1) When only a single current level "400A" needs to be matched, the expression $A==400 is written, where A represents the current level parameter and "==" represents the operator for judging equality. In this way, the system can quickly retrieve the corresponding model with a current level of 400A. (2) For the complex situation where the current level is between "530A-2000A" and the copper busbar specification is "650", the expression "$A>=530&&$A<=2000&&$G=='650'" is written. Here, "&&" is the logical AND operator, which means that the three conditions must be met at the same time, so as to accurately locate the parameterized model that meets these conditions at the same time. As an example, the selection rule base of the product parameterization model is shown in Table 4 below: Table 4

[0032] Among them, in step S40, if Figure 4 As shown, the method for screening, filtering and matching calculation of the pre-generated bus duct product list using the selection rule library includes the following steps: S41. Preliminary screening of the bus duct product list based on fixed screening conditions of the selection rule library; S42, enabling variable screening conditions to perform secondary screening on the bus duct product list after the initial screening; S43, extracting various product parameters on the bus duct product list after secondary screening, and performing matching calculation on the extracted product parameters; S44, verifying and feeding back the matching calculation results.

[0033] As an example, first, the busbar direction, wiring method, category, type, current level, production process and other product parameter information are designed in CAD according to the actual on-site measurement results, and a bus duct product list containing busbar direction and bus duct product parameter information is generated as shown in Table 5 below. The product list includes the bus duct line number (busbar serial number, direction and other information), product unit sequence number, quantity, current level, electrical system category, copper busbar selection specifications, protection level, X / Y / Z parameter change (size information).

[0034] Table 5

[0035] Next, a preliminary screening is carried out according to the product category and type of the bus duct. For example, the parametric models with the product category of XMS-E and the product type of ST include XMSEST4604PE, XMSEST45 / 620PE6*50, XMSEST45 / 620PE6*60 and XMSEST45 / 640PE.

[0036] Then, substitute the values ​​of other parameter variables into the variable screening conditions for calculation. For example, when the current is 400A and the copper busbar specification is 3*50, the only parameter model matched is XMSEST4604PE, as shown in Table 6 below: Table 6

[0037] Among them, in step S50, if Figure 5 As shown in FIG. 1 , the method of substituting various parameters in the bus duct product list into the matched parameterized model in the form of variable values ​​for calculation includes the following steps: S51. Identify the key parameters on the bus duct product list and organize the identified key parameters into a standardized format; S52, establishing a mapping relationship between the sorted key parameters and the variables in the matched parameterized model; S53. According to the mapping relationship, the key parameters are sequentially substituted into the matched parameterized model for layer-by-layer calculation to obtain the bill of materials and process parameters of the bus duct product unit.

[0038] For example, for the line XAB01 ​​in the product list, product serial number 0003, product type ST, product quantity 1, its parameters include current level A=400A, electrical system category E=45, copper bus specification G=3*50, protection level P=IP54 and length variable X=650. Substituting the above parameter variable values ​​into the XMSEST4604PE parametric material model to calculate the generated material process parameters are shown in Table 7 below: Table 7

[0039] Substituting the above parameter variable values ​​into the XMSEST4604PE parametric BOM model to calculate the generated material BOM structure is shown in Table 8 below: Table 8

[0040] Repeat the above operations to calculate the process parameters of the material generated by the next layer of parameterized material model and the BOM structure of the material generated by the parameterized BOM model, as shown in Table 9 and Table 10 respectively: Table 9

[0041] Table 10

[0042] Among them, in step S60, according to the material and the material's process parameters, combined with the drawing model associated with the material model, the corresponding two-dimensional engineering drawings of each self-made part under the bus duct product are generated. When the copper bar parts under the LL / LR type horizontal elbow unit use the design drawing collection model, directly reference Figure 7 When the lower side panel of the ST through unit uses a design file model, the material and its process parameters need to be sent to the CAD software for drawing generation. Furthermore, the two-dimensional engineering drawings, bills of materials and production process sheets generated above are stored in the project design database, and the production execution system performs unified scheduling and execution management, thereby realizing parameterization and automation in the entire design process.

[0043] It should be noted that the method of the embodiment of the present invention can be performed by a single device, such as a computer or a server. The method of this embodiment can also be applied in a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present invention, and the multiple devices will interact with each other to complete the described method.
