摘　　要：本文介绍了基于工业以太网通信变频器的设计思想,在分析网络变频器的通信机制的基础上,建立了一种基于数据通信优先级分类的工业以太网通信控制策略。系统利用上位机PID算法,根据网络传递的水位信号计算变频器输出频率,从而控制双容水箱水位。实验结果表明,通过这种工业以太网通信可有效地控制变频器进行双容水箱水位控制。The paper presented a kind of frequency converter based on industrial Ethernet. The system design and network control mechanisms are discussed. The article analyzed the network communication mechanism, and established one kind industry Ethernet based on the data communication priority classification. The system has been tested by experiment. The experimental results show that the converter can be controlled through network in double- holding water tank water level control.
