This application is based on the attribute information of AutoCAD graphic data, and based on the scalability, editability and extractability of the attribute information of graphic data, according to the electrical interconnection design requirements of complex systems, the design data such as electrical names, connection terminals, unit coordinates, and interconnection relationships are structured for storage, management and application to complete the definition of electrical graphic models; combined with the electrical interconnection composition and design rules of complex systems, an electrical graphic model library consisting of multiple models such as low frequency, radio frequency, light, line number, and destination is predefined.

[0039] In the process of designing the electrical interconnection relationship of a product or system into a graphically presented drawing through a CAD tool, this application calls and instantiates a specific electrical graphic model based on the user's design data, automatically maps and stores the electrical interconnection data according to the predefined attribute set of the model, and realizes the vectorization and digitization of massive electrical design data of complex systems. At the same time, the electrical interconnection twin of the product or system is constructed in combination with the re-extraction and visualization capabilities of the graphic model data. Based on the construction of twins of design data and graphic data, twin verification of massive electrical design and graphic data of the product is realized through digital methods, effectively ensuring the integrity and consistency of CAD drawings and the electrical interconnection design data of the product or system.

[0040] To achieve the above object, the technical solution adopted by the present invention comprises the following steps:

[0041] Step 1: Electrical graphics data construction.

During the drawing process, use the graphical attribute setting method to automatically fill in the attribute information of each graphic unit, including electrical information, model type, electrical destination information, etc., to complete the construction of electrical graphics data.

[0042] Preferably, in step 1, the present application defines standardized electrical graphic element models such as low-frequency model, radio frequency model, optical model, line number model, and direction model based on standard specifications, and at the same time uses the AutoCAD block characteristics to bind and store attribute information during the graphic unit instantiation process, thereby completing the twin storage of data information and graphic information.

[0043] Step 2: Electrical graphic data extraction: Based on the twins of design data and graphic data, all twin models in the CAD drawings are automatically traversed and the instantiated electrical interconnect design information is extracted for vectorization and structured storage.

[0044] Preferably, in step 2, the present application automatically extracts massive electrical interconnection graphic element information based on the CAD graphic twin instantiation model, and vectorizes and structures the information according to the mapping association relationship.

[0045] Step 3: Matching and mapping of electrical graphic data. Based on step 2, the massive electrical interconnection data extracted, vectorized and structured are matched and paired with the user design data, and a matching mapping file of the electrical interconnection data is automatically generated according to the specifications.

[0046] Preferably, in step 3, the present application automatically fills the electrical description information in the twin model into the design unit that has a connection relationship with it based on the interconnection relationship information in the attributes of the electrical CAD graphic twin model, and generates a copy of the electrical design data according to the standard format of the electrical design data file.

[0047] Step 4: Twin verification of electrical graphics data.

[0049] refer to Figure 2 As shown, the present application is a method for quickly extracting massive electrical graphics manufacturing data based on AutoCAD and automatically twinning the design data. Massive electrical manufacturing data generated by a standard primitive model in AutoCAD is used to automatically extract all basic primitive information with one click, and electrical design data is automatically generated based on the primitive attribute information. The data is then fully automatically compared with the original electrical design data form to complete the twin verification.

[0050] refer to Figure 3 As shown in the figure, in the verification results, when a verification error occurs, all verification information is automatically summarized and displayed graphically. By double-clicking the mouse, the error information can be quickly located in the massive electrical data, and the design optimization can be quickly completed.

[0052] See also Figure 5 ,During the forward verification function verification process, the verification result data is used to ,forwardly generate a new version of the CAD drawing, and the verification function ,is verified with the previous version of the CAD drawing. Modifications are ,confirmed on the drawing side to ensure the correctness of the data ,extraction and twin verification extracted data.

[0053] This application is based on the attribute information of AutoCAD graphic data. Based on the extensibility, editability, and extraction and reuse of the attribute information, a model is built through secondary development to achieve twin verification of graphic data and user design data, ensuring the integrity and consistency of CAD drawings and the electrical interconnection design data of products or systems, and solving the defects and shortcomings of the existing technology.

[0054] This application realizes the consistent mapping and interoperability of CAD drawings and design data by automatically building a twin model. Cross-mapping and verification based on the twin model can quickly detect integrity and consistency issues between massive electrical design and graphic data during the design process; interoperability based on the twin model can quickly iterate electrical interconnection design to match the current requirements for rapid updates and upgrades of complex systems, thereby greatly improving design efficiency and improving product design quality.
