摘　　要：基于对以太网存在的多种延时特性的分析,设计了一种应用于工业现场、可实时数据传输的以太网模型系统。在构建网络时,通过合理划分网段,构建分层的以太网模型,均衡工业现场嵌入式设备的数据吞吐量;在嵌入式软件方面,简化了TCP/IP协议栈,设计了适合于工业现场的应用层协议,大大提高了以太网的实时性,满足了工业以太网高实时性的数据通信要求。该以太网模型已成功应用于苏州工业园区某半导体企业的工业现场数据采集,取得了良好的效果。Based on the analysis of the characteristic of Ethernet, a high real-time industrial Ethernel model was developed. The data transport was balanced by constructing a hierarchical model and the real-time property was enhanced by simplifying the TCP/IP protocol when designing the embedded software. As a resuh, the demand of high real-lime property in the industrial Ethernet model was satisfied. The final model was suecessfully applied to a semi-conduetion company in Suzhou industry area.
