Object chain data construction method and system in PDM system

Abstract

The invention relates to the field of product data management, and provides an object chain data construction method and system in a PDM system, and the method comprises the steps: building a first object chain and a first metadata object through obtaining an engineering drawing file; enabling the engineering drawing file, the first metadata object and the data of the first object chain to enter apreprocessing state, judging whether the three types of data are copied at the same time or not, and enabling the first object chain to enter the preprocessing state at the same time if the three types of data need to be copied simultaneously; performing check-in to judge whether data conflicts exist in the new project or not; and when it is detected that the copy data does not conflict with thenew project, setting the new project to be in a write operation access permission state, writing the engineering drawing file and the data copy of the first metadata object into the new project, and constructing second object chain data. According to the method and the system, the existing part data is copied and reused, the completeness and correctness of the data copied to the new project are effectively ensured through the check-in operation, the data interference, compatibility and conflict are reduced, and the product collaborative design efficiency is improved.

Description

technical field [0001] The invention relates to the field of product data management, in particular to a method and system for constructing object chain data in a PDM system. Background technique [0002] The PDM system (Product Data Management, PDM) manages all product-related information, including part information, configuration, documents, CAD files, structures, authority information, etc., and all product-related processes, including process definition and management. Enterprises implement PDM Systematic management can improve production efficiency, facilitate the management of the entire life cycle of products, strengthen the efficient use of documents, drawings, and data, standardize the workflow, and have a wide range of applications in the process of enterprise product data management. [0003] CN102708213B discloses a method for realizing BOM information transmission between a PDM system and an ERP system. The method sets a BOM transmission interface between the P...

Problems solved by technology

[0006] In view of this, the present invention aims to propose a method for constructing object chain data in the PDM system, so as to solve the unavoidable reuse of component data in the design process of the same family of products in the PDM system. In the simple copy operation process, data interference, compatibility And problems such as conflicts, which affect the efficiency of product collaborative design, the method of building object chain data in the PDM system includes:
