摘要
现场总线技术和 IP网络的融合是测控技术的发展趋势 ,但是传统的测控网络不能直接实现和 IP网络的无缝连接。该文在介绍了基于 Ethernet网络的测控系统的基本模式后 ,针对目前的测控系统接入 Ethernet的方法进行了分析 ,并着重介绍了 8/16位的嵌入系统的 L on Works、EMIT、Scenix、e Z80等几种代表性的网络连接方案 。
The integration of the filedbus technology and Ethernet is the developing trend of the remote measurement and control technology, but the conventional measurement and control network can not be linked directly and seamlessly with Internet Protocol(IP) network. In this paper, the basic modes of the Ethernet-based measurement and control system are described,and the linking methods of the current measurement and control system with Ethernet are discussed,and several representative network linking schemes are analyzed in detail,such as the 8/16-digit embedded LonWorks,Evolutionary Models of Information Transmission(EMIT),Scenix,and eZ80. The application of the above-mentioned schemes to the IP-based video supervising system is also introduced.
