网络化零件库资源集成框架及其关键技术

为了满足网络化制造环境对零部件资源共享与重用的需求，提出基于标准化技术的零件库资源集成框架，并分析该集成框架的基本功能与特点。重点研究实现该集成框架的关键技术，包括扩展PLIB标准(ISO 13584)的网络零件库信息建模技术，以及基于分类编码和事物特性表的零件库内容形式化表达方法。为了适应该集成框架的网络化应用环境，提出基于可扩展置标语言(XML)的零件库信息传输与交互技术，并针对不同的信息交互层次给出相应的XML Schema映射方法。该集成框架能为实现零件资源的异地共享和信息集成提供一个可操作的技术平台。

NETWORKED INTEGRATED ARCHITECTURE FOR PARTS LIBRARY RESOURCE AND ITS KEY TECHNOLOGIES

In order to fill the need of parts resource sharing and reusing in networked manufacture environment, based on several standard technologies, integrated architecture for parts library resource is built. Functions and characteristics of the integrated architecture are analyzed. Especially, key technologies for realizing the integrated architecture are studied, including the information modeling technology for parts library in networked environment by extending PLIB standard(ISO 13584)and the formalized-expression method for parts library content based on tabular layouts of article characteristics together with classification & code technology. Furthermore, in order to adapt to the networked application environment, XML-based parts library information exchanging technology is built, meanwhile, for constructing XML Schema two mapping methods corresponding to two different information exchanging levels are present. The integrated architecture provides operable technology platform for the share of distributed parts resource and information integration.
