基于现场总线的嵌入式系统多协议转换系统研究

摘要

本文介绍了现场总线和工业控制系统网络概况，分析了现场总线技术和工业控制的现象和特征。在理论上阐述现场总线的主要构成与特点，并介绍了相关总线技术类型。文中涉及的三个现场总线协议，理论上通过以太网可以完成协议转换，为设计的试验操作提供了扎实的基础。通过分步分解的试验方法，将整体方案分解为三小块方案，在试验中得到了完善。%This paper introduces the overview of the fieldbus and industry control system. Second, it analyses the phenomena and characteristics of it. Third, the structure and characteristics of fieldbus were followed theoreti- cally. Fourth, it also introduces the type of bus technology. The there technology of fieldbu,; protocol can be con- versed to each other by Ethemet theoretically. It is a credible base of experimentation operation for the design. It break down the total project into there parts through experimentation step by step. The project was perfected in the test.
