Design knowledge tracing method and system in CAD system based on block chain

Abstract

The invention relates to the field of digital design, and provides a design knowledge tracing method and system in a CAD system based on a block chain, and the method comprises the steps: collecting design knowledge node data, user information data and equipment information data in an active window in the CAD system, and storing the data in a local storage unit; and verifying the knowledge node data, writing calculated Hash values, Hash values and backup addresses of the knowledge node data, the user information data and the equipment information data in a local storage unit into a block chainprivate chain, and anchoring a block chain private chain module into a block chain public chain module; The invention further provides a system for implementing the method, the situation that the structure, parameters and format of data such as texts are disordered and the design knowledge cannot be effectively traced back due to the fact that the design knowledge data is modified for multiple times is prevented, and therefore development of new design activities in a CAD system can be effectively supported, and the digital design efficiency of products is improved.

Description

technical field [0001] The invention relates to the field of digital design, in particular to a method and system for tracing design knowledge in a blockchain-based CAD system. Background technique [0002] In the process of digital design, computer aided design (Computer Aided Design, CAD) system is usually used to help designers carry out design work through computers and graphics equipment, which is not only efficient, but also conducive to collaborative design in different places. In the process of product digital design, The computer can perform a large number of calculations, analyzes and comparisons on different schemes, and generate a large number of various design information, whether it is digital, text or graphics, which can be used for a series of subsequent designs and reuse. CAD systems are used in electromechanical Products, construction, transportation and other fields have a wide range of applications. [0003] CN 106471503 B discloses a method for product ...

AI Technical Summary

Problems solved by technology

[0004] In the existing digital design system, designers search or retrieve the required design knowledge data by themselves, but the retrieved design knowledge data is often not structured data that meets the requirements, and design activities generate a large number of design knowledge data. The inability to effectively update has resulted in outdated design knowledge data. The most important thing is that some design knowledge data has been modified many times, and the source of design knowledge cannot be well traced. Moreover, the structure, parameters, and format of text and other data are chaotic, making it difficult to Support the development of new design activities in the CAD system, resulting in low efficiency in product digital design
