摘要
给出了一种基于微控制器的以太网通信节点功能描述和硬件原理。在工业现场设备嵌入精简TCP/IP协议族,完成了基于以太网的数据通信,建立了协议分层模型,分析了软件技术问题,阐述了各层协议的实现过程,提出并讨论了开发与实现过程中易忽略和误解的若干技术细节。该设计已在工厂温度监控系统中成功应用。
The function description and hardware principle of EtherNet communication node based on microcontroller were given. The reduce TCP/IP protocol suite was embeded in industry field devices and data communication based on EtherNet was completed. The protocol layer model was built and the software technology item was analysed. The realization course of every layer protocol was expounded. Then several technical details which are easily ignored and misunderstood in development and realization were put forward and discussed. The design has been successfully applied in temperature monitoring system of factory.
