摘要
为了实现企业设备控制层到数据管理层的信息集成,采用工业以太网和现场总线混合控制网络,可以实现控制和管理的有机统一。采用Maxim公司推出的8051家族中的微控制器 DS80C400芯片,利用微型因特网接口(Tiny Internet Interfaces-TINI)平台,采用JAVA语言,应用套接字技术、OPC技术和JAVA多线程技术,完成了工业以太网和CAN总线网络间嵌入式网关的设计, 给出了两层网络间通信软件设计的方法。方案以CAN总线为底层控制网络,以太网作为上层管理网络,中间为嵌入式网关,网关实现了异质网络之间的无缝连接。
To realize the information integral of the device control layer and the data management layer, mixed network of Ethemet and Field- bus is introduced to realize the unification of control and management. The chip of Maxim DS80C400 (8051 family) is adopted. By using Tiny Internet Interfaces (TINI)Platform and, JAVA Language with the technique of socket, OPC and multithreading, the design of embed gateway is given. The method uses CAN network as the bottom control net, and Ethemet as the manage net. The embed gateway realizes the perfect coniunction of different network.
