嵌入式以太网在工业测控系统中的应用

Application of Embedded Ethernet in Industrial Measure and Control System

传统的现场总线由于标准不统一、传输速率低等局限性已经不能满足工业测控系统通信的要求,以太网技术凭借通用性强、技术成熟、带宽迅速增加等特性成为现场总线技术发展的新亮点。特别是随着嵌入式技术的出现,嵌入式以太网为工业测控系统提供了开放式、分布式、可互操作性的通信平台。

Due to the lack of unified standards, low communication speed and some other limitations, traditional fieldbus can not satisfy the requirements of industrial measure and control system. Ethernet technology, which is versatile, mature and with fast increasing bandwidth, have been the highlights of fieldbus technology. In particular, with the emergence of embedded technology, embedded Ethernet provides an open, distributed and interoperable communications platform for industrial measure and control system.
