基于网络的计算机与变频器的通讯及控制

Communication and control between computer and inverter based on the Ethernet

目前,越来越多的高性能变频器以数字信号处理器(DSP)作为控制核心。本文设计并实现了一种基于以太网的变频器和计算机的通讯方法,能够灵活方便地对变频器运行进行实时监控,大大提高了DSP程序开发的效率。软件基于TCP IP协议,方便灵活。硬件结构简单,成本低。软、硬件结构都具有良好的扩展性。

DSPs are widely applied as controllers of highperformance inverters. This paper designs a new method based on the Ethernet, which can realize the communication between inverters and computers under the TCP/IP protocol. It greatly improves the efficiency of developing the DSP programs, and can monitor the inverters in realtime. It has advantages of low cost and simple operation. Both of the software and hardware can be easily extended.
