Description

Technical Field

[0001] This invention relates to the field of equipment design methods, and in particular to a rapid equipment design method based on CATIA Automation secondary development. Background Technology

[0002] Equipment design methodology refers to the application of specific principles, technologies, and methods to design and develop various types of equipment. It encompasses the design process from the initial concept of the equipment to the final product. Equipment can be any specific mechanical, electronic, chemical, or other type of system used to perform a specific function or meet specific needs. The main objective of this methodology is to design equipment that meets specific requirements, taking into account factors such as performance, functionality, reliability, safety, and economy during the design process.

[0003] CATIA is a computer-aided design software widely used in automotive, aerospace, shipbuilding, steel structure plant design, architecture, power and electronics, consumer products, and general machinery manufacturing.

[0004] Due to the file saving and management, product assembly, and other related characteristics of software, it is necessary to write the same type of numbering to distinguish parts with different characteristics and the hierarchical relationship between products and parts, and to reasonably save the file link address. However, when using CATIA software to design a device, it is generally necessary to manually edit the numbering of each component, product, and part, and select the file saving link address. The operation is too cumbersome, and designers have to spend a lot of time writing numbers and saving addresses, which reduces work efficiency. Summary of the Invention

This is of great significance for completing device design tasks quickly and efficiently.

[0097] Please see Figure 4 Using equipment parameter information and regular expressions for checks, sub-product documents are generated and saved according to the design tree structure. The specific steps for generating sub-product documents are as follows:

[0098] S310: Based on device parameter information, after the user clicks the "Create Blank Unit" button, a regular expression is used to perform a validity check to confirm the validity of the unit number;

[0099] S320: Using the object navigation algorithm, extract the sub-document set Products from the passed-in application object to obtain the sub-document set of the currently active document;

[0100] S330: Based on the sub-document set, using the recursive tree algorithm, generate sub-products according to the design tree specification and create the design tree structure of the sub-products;

[0101] S340: Based on the design tree structure, rename the sub-products to obtain the renamed sub-products and generate sub-product documents.

[0102] First, regular expression validation ensures that the unit numbers of created sub-products conform to the prescribed format and requirements. This reduces the possibility of errors and inconsistencies, ensuring the validity and accuracy of sub-product identifiers. Second, an object navigation algorithm is used to extract the sub-document set `Products`, enabling quick access and management of existing sub-product documents. This simplifies the process of finding and processing sub-product documents, improving operational efficiency. A recursive tree algorithm is used to generate the design tree structure of sub-products, ensuring that each sub-product is in the correct position and associated with its parent product. This helps to build a clear and orderly design tree structure, improving the visualization and manageability of the design. Finally, sub-products are renamed according to the design tree structure, generating sub-product documents with meaningful identifiers. This facilitates subsequent searching, identification, and management, improving operational accuracy and efficiency. In summary, this rapid device design method, through steps such as validation, object navigation, recursive tree algorithms, and renaming, brings beneficial effects such as reduced errors, improved operational efficiency, the construction of a clear design tree structure, and convenient management. This is of great significance for quickly and efficiently generating sub-product documents and saving them according to design requirements.

[0103] Please see Figure 5 Based on the sub-product document, the steps to select the insertion point and generate a new part number, determine and insert or create a new part according to the attribute table, rename and save, and generate a complete part document are as follows:

[0104] S410: When a user clicks the "Add Part" button in a sub-product document, the depth-first search algorithm is used to select the assembly to which the part will be inserted and to determine the insertion position of the part.

[0105] S420: Generate a new part number using a hash map based on the part insertion position;

[0106] S430: Based on the attribute table, determine whether a reference part exists and confirm the existence of the reference part;

[0107] S440: Based on the existence result, select the method to insert or directly create a new part, and generate a part object;

[0108] S450: Rename and save the part object to generate a complete part document.

[0109] First, a depth-first search algorithm is used to select the insertion point, ensuring the correct connection and assembly of the new part with other parts. This improves design accuracy and assembly quality, ensuring correct connections and combinations between parts. Second, a new part number is generated through hash mapping, ensuring the new part has a unique identifier. This avoids duplication and confusion, allowing each part to be independently identified and identifiable. The existence of a reference part is determined based on the attribute table, and the appropriate method is selected to insert or create a new part, generating a part object. This improves design flexibility and efficiency, allowing for the reuse of existing parts or the creation of a new part object as needed. The part object is renamed and saved, generating a complete part document. Renaming the new part ensures it has an accurate and meaningful identifier, and this process is then saved. This facilitates subsequent searching, identification, and management operations, improving accuracy and efficiency. In summary, this rapid design method for equipment, through steps such as selecting the insertion point, generating a new part number, attribute table judgment, and renaming and saving, brings beneficial effects in design accuracy, flexibility, and efficiency.

Second, obtaining the reference unit document address ensures correct referencing and access to the reference unit document, providing necessary information and basis for subsequent operations. By copying all parts from the reference unit document to the active product address, it is ensured that the active product has the same part composition as the reference unit, improving product consistency and accuracy. The part files are then inserted into the active product document, creating and saving a complete product unit document. This step ensures the integrity and integration of the product unit document, simplifying the product design and management process. In summary, this rapid design method for equipment, through steps such as validity checks, template unit document reading, and part copying and insertion, brings beneficial effects such as reducing errors, improving data accuracy, enhancing product consistency, and simplifying the design process. This is of great significance for the rapid and efficient creation and saving of complete product unit documents, and provides convenience and manageability for product design and management.

[0121] S235: Summarize the device number detection results and address detection results, determine the validity of the device number and data storage address entered by the user, and generate an input validity verification result.

[0122] First, preliminary detection and anomaly handling eliminated common input errors and formatting issues, improving data accuracy and validity and reducing the possibility of erroneous operations. Second, the anomaly handling mechanism promptly captures and handles abnormal situations, such as blank input, incorrect input type, and incorrect address format, mitigating the risk of system errors and improving system stability and reliability. Furthermore, the validity verification results provide clear feedback, allowing users to quickly understand and correct input errors, improving user experience and efficiency. In summary, by verifying the validity of device serial numbers and data storage addresses through anomaly handling mechanisms, this device design method enhances data accuracy, system stability, and improves the reliability and efficiency of user operations.

[0128] S315: Based on the unit number detection results, confirm the legality of the unit number.

[0129] First, using regular expressions for validity checks efficiently and accurately verifies whether user-input unit numbers conform to the specified format requirements, reducing the workload of manual item-by-item checks and improving operational efficiency. Second, validity checks promptly identify and eliminate non-compliant unit numbers, preventing erroneous data input and ensuring the validity and compliance of unit numbers in the system. Furthermore, validity check results are promptly fed back to users, providing clear validity information to help them understand whether the unit numbers are valid, reducing user errors and facilitating timely correction of input mistakes. Additionally, regular expression matching effectively prevents duplicate unit number input, ensuring the uniqueness and consistency of unit numbers in the system, improving data accuracy and system stability. In summary, by using regular expressions for validity checks based on device parameter information to confirm the validity of unit numbers, this device design method improves operational efficiency, accuracy, and data consistency while reducing the risk of erroneous input. This is of great significance for the smooth progress of device design and the reliability of data management, providing a guarantee for achieving high-quality device design and data processing.

[0130] Please see Figure 9 The specific steps for extracting the sub-document set "Products" from the passed-in "application" object using the object navigation algorithm to obtain the sub-document set of the currently active document are as follows:

[0131] S321: Use an object navigation algorithm to parse the incoming application object and generate a parsed application object;

[0132] S322: Based on the parsed application object, extract the sub-document collection Products and generate the sub-document collection Products;

[0133] S323: Use an object navigation algorithm to further parse the sub-document set Products to obtain the sub-document set of the currently active document.

[0134] First, using an object navigation algorithm to parse and navigate the application object improves code flexibility and maintainability. By parsing the object structure and accessing related attributes and associated objects, hard-coded dependencies are reduced, making the code more scalable and readable, and facilitating subsequent modifications and maintenance. Second, directly navigating to the target sub-document set, Products, through the object navigation algorithm improves data access efficiency. Inefficient traversal and search operations are avoided, reducing time and resource consumption and thus accelerating the retrieval of the sub-document set. Furthermore, the object navigation algorithm ensures the accuracy and completeness of the extracted sub-document set. By extracting the Products set from the parsed application object and further parsing to obtain the sub-document set of the currently active document, it ensures that the extracted data matches the actual requirements, reducing the risk of errors and data inconsistencies. In summary, by utilizing the object navigation algorithm to extract the sub-document set Products from the input application object, this method improves code flexibility and maintainability, enhances data access efficiency, and guarantees data accuracy and completeness. This provides a reliable data foundation for subsequent operations and processing, offering valuable support for the application's functionality and performance.

[0135] Please see Figure 10 On the complete part document, when the user clicks the "Create Unit" button, a validation algorithm is introduced to check the legality of the input. The specific steps for validating the input legality of unit creation are as follows:

[0139] S514: Verify the legality of the input for unit creation based on the detection results of the unit creation information.

[0140] First, validation algorithms improve data accuracy and consistency. By inspecting the user-input unit creation information, it ensures that the input conforms to predefined rules and constraints. This effectively prevents erroneous or invalid input from entering the system, reducing the risk of data inconsistency and errors, and improving data quality and reliability. Second, the introduction of validation algorithms provides a better user experience. Through timely detection and prompts, users can quickly understand whether their input is valid and correct errors promptly. This avoids unnecessary errors and rework, improves the accuracy and efficiency of user operations, and enhances user satisfaction and trust in the system. Furthermore, validation algorithms prevent the risk of illegal operations and data corruption. By identifying illegal input behaviors, such as invalid formatting or incorrect content, the system can promptly intercept and prevent potential illegal operations, protecting the integrity and security of system data.

[0141] Working Principle: This method initializes the application's COM object and synchronizes the Catia application object using Catia macro commands and DLL call technology. Reflection and data stream parsing are used to initialize the window and property table, generating an initialized user window. Within the user window, the device number and data storage address are input by the user, and their validity is checked to generate device parameter information. The user-input device number and data storage address are ensured to conform to the specified format and requirements. Using device parameter information and regular expressions, a sub-product document is generated. Based on the device parameter information and design requirements, the sub-product document is saved according to the design tree structure. Based on the sub-product document, an insertion point is selected, and a new part number is generated. The property table determines whether a part needs to be inserted or created. The part is renamed and saved, generating a complete part document. Based on the complete part document, validity checks and template unit document reading are performed. All parts are copied to the address of the active product, and product unit insertion is completed. Finally, a complete product unit document is created and saved. Through these steps, the rapid device design method based on CATIA Automation secondary development can automate the device design process, improving design efficiency and accuracy. Users input the device number and data storage address, and the system generates sub-product documents and complete part documents based on the device parameter information, ultimately creating a complete product unit document. This method simplifies the design process, reduces errors, and improves design consistency and repeatability.
