基于Internet的嵌入式工业设备网关

嵌入式工业设备网关是实现工业现场设备和以太网互联的新型网络接口设备,适用于改造现有的现场总线网络,在使用现有的现场总线控制网络的情况下,又实现了与Internet的集成,解决了设备的直接上网问题。在分析工业设备远程监控的新需求现场总线的局限性以及现场总线和Internet技术逐渐融合的基础上,提出了适合于改造现有现场总线和Internet互联的解决方案,即采用基于Internet的嵌入式工业设备网关实现设备直接上网。阐述了现场总线和TCP／IP网络之间的协议转换模型,最后给出其在工业自动化中的典型应用方法以及应用前景和发展趋势。

Embedded Industrial Devices Gateway Based on Internet

Embedded industrial devices gateway is a new network interface to implement interconnecting between field devices and Ethernet,which is fit for rebuilding current fieldbus network.The embedded industrial devices gateway realized not only the integration with Internet,but also the direct communication between field devices and Internet without abandoning actual fieldbus network.Brought forward an effective solution used to rebuild current fieldbus,based on the analysis of the new requirement of the industrial remote monitoring and control,the limitation of the field bus,and the developing trend between fieldbus and Internet.Furthermore,proposed the protocol-transform-model between typical fieldbus network and TCP/IP network.Finally,the expounded the application method in industrial automation,and pointsed out the application foreground and future tendency of embedded industrial devices gateway.
