[0077] Application Example 1:

[0078] The design method is applied to the logistics equipment design system, and the data storage layer of the logistics equipment design system is a modular platform. The logistics equipment design system also includes: a front-end display layer, a business processing layer, and a data interface layer. The configuration parameters are input through the front-end display layer, and the business processing layer calls the data of the modular platform through the data interface layer to realize business processing;

[0079] The business processing layer includes: structure module screening module, structure module parameterization processing module, structure module layout module, bill of materials BOM output module, quotation module, parts drawing export module, installation drawing export module, 3D scheme drawing export module, project management module;

[0080] The structural module screening module obtains the main parameter value input by the parameter setting module, screens out the corresponding structural module from the configuration logic library in the data storage layer according to the main parameter value, and calls the screened structural module from the structural module library;

[0084] The structural module arrangement module arranges the structural modules after parameter assignment according to the position calculation logic and module interface relationship in the product architecture library to obtain a solution model, and the solution model is used for subsequent solution model revision to obtain an accurate solution model;

[0085] The BOM output module outputs the BOM according to the revised solution model, and splits it into application forms for subsequent different links according to given principles to support subsequent work in procurement, delivery and other links.

[0086] The quotation module generates a quotation sheet for a specific solution based on the generated bill of materials and quotation rules in the quotation principle library, as well as the parent-child relationship in the structure module library, to support pre-sales quotation and cost accounting during sales; the parent-child relationship is a hierarchical relationship in the structure module library;

[0087] The parts drawing export module automatically generates the parts drawings of the parts in the bill of materials according to the bill of materials, the parts drawing frame template and the parts drawing annotation principle, and annotates them to support production;

[0088] The installation drawing export module calls the installation steps in the installation step library and the technical requirements in the technical requirements library according to the revised solution model and the bill of materials, and generates corresponding installation drawings and installation requirements to support on-site installation;

[0089] 3D scheme diagram export module: Based on the revised 2D scheme model and the bill of materials, the 2D structure library and 3D structure library in the structure module library are called to automatically match the 3D structure module model. According to the 2D structure module instance parameters, the 3D structure module model is assigned parameters to generate a 3D structure module instance. According to the location information, interface information and 3D structure module instance of the revised scheme model, a 3D scheme diagram is generated. The actual scheme situation is displayed more intuitively, so that engineers can conduct corresponding interference checks and avoid unnecessary errors.

[0090] Project management module: used for creating, copying, editing and storing projects.

[0091] These business processing modules are independent of each other but also complement each other. You can select certain modules according to actual needs to generate a corresponding configuration system for application.

[0092] The front-end display layer consists of two parts. The first part is used to guide users to select and input correct parameters to generate solutions that meet customer needs. The first part includes the main parameter setting module of each module based on modular analysis, the scenario-based business process display module, and the solution model display module generated according to the parameter setting; the other part is the front-end display layer for administrator users to maintain the database, which includes a library management module for adding, deleting, and modifying files in the data storage layer.

[0093] The steps of applying the automatic configuration design system based on the modular platform to perform configuration design and generate order product models and data are as follows:

[0094] 1. Create a new project;

[0095] 2. According to customer needs, select configuration parameters through the front-end display layer interactive interface;

[0096] 3. The system automatically matches modules according to the input parameters and generates corresponding module entities, arranges them according to preset rules, and generates a solution model;

[0097] 4. Revise the parts of the generated solution model that do not meet customer needs;

[0101] 8. Generate installation drawings based on the revised plan;

[0102] 9. Generate a three-dimensional plan drawing based on the revised plan.

[0103] In addition, the automatic configuration design system based on the modular platform can also be used for variant design. The steps for generating order product models and information are as follows:

[0104] 1. Find an instance;

[0105] 2. Copy the project;

[0106] 3. Revise the parts of the generated solution model that do not meet customer needs;

[0107] 4. Generate BOM and other forms based on the revised plan;

[0108] 5. Generate parts drawings based on the revised plan;

[0109] 6. Generate a quotation based on the generated BOM;

[0110] 7. Generate installation drawings based on the revised plan;

[0111] 8. Generate a three-dimensional plan drawing based on the revised plan.

[0112] Application Example 2:

[0113] 1. Create a new project;

[0114] 2. Input the main parameters required by the customer on the page (a collection of the main parameters of each structural module), such as beam span W=850mm, shelf height H=8500mm, number of layers I=13 (single layer height is 600mm), single cargo grid load G=50kg, etc.;

[0115] 3. According to the input parameters, the corresponding modules are matched logically and the corresponding module entities are generated. The layout is performed according to the preset rules to generate the solution model. Table 1 shows the module selection logic. Different column models correspond to different movable foot modules and adjustable foot modules. Table 2 shows the module selection and module relationship logic. Table 3 shows the interface relationship. The ellipsis in the table indicates that there are other modules or parameters besides the examples.

[0116] Table 1 Module selection logic

[0117] (1) Based on input parameters, such as the input shelf height and number of layers For single-grid load (total load of single-row rack), select column modules LZ-50, HDDJ-50 or TJDJ-50.

[0118] Table 2 Module selection and module relationship logic

[0119] According to the column model and input parameters (beam span), select the beam module HL-80_50.

[0120] (2) Assign parameters to the module and generate the corresponding module entity:

[0121] Assign the shelf height H=8500mm to parameter 1 of the column; assign the beam span W=850mm to parameter 2 of the beam to obtain the actual module entity.

[0122] (3) Calculate the position of each module according to the interface relationship and position calculation logic:

[0123] Table 3 Interface relations

[0124] For example, the column LZ-50 is connected to the HDDJ-50 through the interface A. The "-" in the table indicates that there is no interface relationship.

[0125] For example, the height position of the beam is determined by the interface type (A, B, C) and the single-layer height.
