CAD collaborative design method based on semantic information exchange

Abstract

The invention relates to a CAD collaborative design method based on semantic information exchange, and the method comprises the steps: organizing CAD data generated in a product design process into a CAD data semantic structure of a natural language, reflecting a product design intention through the CAD data semantic structure, completely expressing the product design intention and a design change maturing process, and using the CAD semantic event exchange technology to solve the problems of CAD design teams, remote design teams, heterogeneous design tools and cooperative work in the teams in cross-professional fields. Sharing and transmission of CAD design data are facilitated, an electronic design team and a structural design team can mutually perceive design changes and changes in real time, the difference between different versions of drawings is identified, the business dependence between data and the design intention are effectively expressed, shared and reused, the electronic and structural design collaboration is accelerated, the interference problem between the electronic and structural design is solved in time, the real-time collaboration in a team is facilitated, and the team management work is reduced.

Description

technical field [0001] The invention relates to the technical field of design collaboration, in particular to a CAD collaborative design method based on semantic information exchange. Background technique [0002] At present, most product designs are a process of collaborative design in multiple professional fields, including structural design, hardware design, and software design. The industry often uses some management means, or in the professional field, to achieve some partial collaborative work under the condition of using the same design tool, but does not really solve the effective collaboration between cross-teams, cross-regions, and different design tools from technical means. [0003] In the field of product design, the Top-Down Design (top-down) design method is used to decompose the product modules, generate top-down design tasks, assign them to different design teams, and use the central database to collect task deliverables. For example, a typical PDM system m...

Problems solved by technology

[0003] In the field of product design, the Top-Down Design (top-down) design method is used to decompose the product modules, generate top-down design tasks, assign them to different design teams, and use the central database to collect task deliverables. For example, a typical PDM system manages product R&D data to realize the process management of product R&D and the sharing and exchange of product R&D data, but this method has the following typical problems: 1. In many cases, engineers do not design all the process versions Records, that is, the procedural versions of CAD data are not fully submitted to the central database or PDM system, resulting in the teams not being able to perceive each other's design changes and changes in real time; 2. Although the designed drawings are uploaded to the central database or PDM system by engineers , the PDM system cannot recognize the differences between different versions of the drawings, and the changed content needs to be actively informed or passively discovered by engineers; 3. The drawings designed for structure, electronics, and electrical have a large capacity, and they are uploaded and archived to the central data or PDM system 4. Although the central database or PDM system collects and manages product design data, it only archives the design data. The business dependencies and design intentions between them have not been reflected, and cannot be effectively expressed, shared, and reused as knowledge
