Product unified model construction system based on semantic meta model and construction method thereof

Abstract

The invention relates to a product unified model construction system based on a semantic meta model and a construction method thereof, and belongs to the technical field of product modeling. The system comprises a human-computer interaction interface (000), a product modeling subsystem (100), a product semantic meta model definition and management subsystem (200) and a product model management subsystem (300). The human-computer interaction interface is connected with the product modeling subsystem, the product semantic meta model definition and management subsystem and the product model management subsystem. The product modeling subsystem is connected with the product semantic meta model definition and management subsystem and the product model management subsystem. Compared with the systems and the methods in the prior art, a multi-level product modeling framework is constructed through combination of the meta modeling mechanism and the ontology technology so that product geometric and non-geometric information semantic description can be realized, and product life cycle information integration, sharing and reusing can be realized; and design personnel can create normal product information models without being proficient in the ontology thought or the modeling language internal structure so that the design efficiency and quality can be enhanced.

Description

technical field [0001] The invention relates to a unified product model building system and a building method, in particular to a semantic metamodel-based product unified model building system and a building method, belonging to the technical field of product modeling. Background technique [0002] Product information integration, sharing and reuse technology has always been the primary problem to be solved in the integrated application of CAx / PDM. It is necessary to focus on the design and manufacturing requirements of products, and realize the semantic level sharing and reuse of product information among distributed enterprises with product innovation as the core. , to achieve interoperability of product information between heterogeneous systems. However, the traditional product information expression and processing mode can no longer meet the needs of modern manufacturing enterprises, and the development of product information exchange and sharing technology has shifted f...
