Product Data Sharing Modeling And Data Acquisition Technology

Collaborative design and manufacturing is becoming a trend for manufacture enterprises.Thus, product information sharing technology which is the basis of collaborative design and manufacturing attracts a lot of attention by enterprises.This paper studied the shared product information modeling and the data-capturing technology which are the keys of product information sharing technology.Managers or technician build a product information sharing master model for the whole enterprise and set paths of product data for entity attibute.The pathes show where product data is saved and it is called mapping information in this paper.The component of the product information sharing platform captures the product data according to the model including mapping information and builds a product sharing information document in XML format. The following key problems are studied in this paper:1) Genaration of product information sharing master model. An aided tool was designed and implemented to help technician build a product information sharing master model.It is based on IDEFlx and provided some model elements and guidance for users to build the product information sharing master model more easily.2) Mapping between product information sharing master model and actual product data. Some connection between product information sharing master model and product data was built according to the metadata of heterogeneous database by administrator of the product information sharing platform. And a new product information sharing master model was built .It included some mapping information and was saved as an XML file.3) Data Capturing for product information sharing master model. A component was designed and implemented and it captured product data from heterogeneous database according to the product information sharing master model and mapping information.It sovled some problems such as multi-source queries, data-driven model and context-dependent model.It also built an XML file for product sharing information.
