Problems solved by technology
[0006] In view of this, the present invention aims to propose a method for traceability of technical parameter changes in the PDM system to solve the problem of determining the original sequence of task adjustments caused by engineering changes in the PDM system when engineering changes occur or product design projects end. , cannot effectively trace the source of other node changes caused by engineering changes and other technical parameters that cause changes, which in turn leads to the problem that the real original data of each collaborative design link is unclear. The traceability methods for technical parameter changes in the PDM system include:

The invention relates to the field of product data management, and provides a technical parameter change tracing method and system in a PDM system. The method comprises the following steps: acquiringoriginal technical parameter data in a PDM system; generating a first verification code, obtaining changed technical parameter data in the PDM system; generating the second verification code accordingto the changed technical parameter data and the first verification code, sequentially obtaining the Nth changed technical parameter data, generating an Nth verification code according to the Nth changed technical parameter data and the (N-1) th verification code, and storing the Nth changed technical parameter data and the Nth verification code in a local storage unit; copying and storing all thetechnical parameter data and the verification codes on M pieces of equipment of the product collaborative design respectively, so that a series of tasks can be traced back to adjust veins according to data in a block chain, excessive loss or other malicious data changes are prevented, data tampering is prevented, repeated design problems are reduced, and the product collaborative design efficiency is improved.
Description
Technical field [0001] The invention relates to the field of product data management, and in particular to a method and system for tracing technical parameter changes in a PDM system. Background technique [0002] The PDM system (Product Data Management, PDM) manages all product-related information, including part information, configuration, documentation, CAD files, structure, authority information, etc., as well as all product-related processes, including process definition and management. Enterprises implement PDM System management can improve production efficiency, help manage the full life cycle of products, strengthen the efficient use of documents, drawings, and data, standardize work processes, and have a wide range of applications in the process of enterprise product data management. [0003] US Patent US10614177B2 discloses a system, method, and program for a PDM system. The system includes: one or more digital production equipment for manufacturing three-dimensional obje...
