基于STEP和XML的产品数据交换与集成在网络化制造中的应用

Applying STEP & XML Based Product Data Exchange and Integration to Networking Manufacturing

Internet上大量异构信息的存在是制造业向网络化发展的障碍。本文首先阐述了STEP标准、EXPRESS语言和XML的基本概念 ,分析了ISO 10 3 0 3Part2 1中性文件作为数据交换手段的不足 ,以及用XML来替代它的可能性与必要性 ,讨论了EX PRESS到XML的映射机制和方法 ,在此基础上结合应用广泛、发展较为成熟的XML相关规范和XML解析工具 。

Heterogeneous information on Internet is an obstacle of network manufacturing This paper explains the STEP, EXPRESS modeling language and XML, and analyses the deficiency of ISO 10303 Part21 system-neutral file as the data exchange way Then it brings forward the possibility and necessity of substitution with XML Consequently, it discusses the reflection mechanism from EXPRESS to XML, and, based on this, proposes a simple model for product data exchange system among manufacturing enterprises combining relevant specifications and parse tools of XML
