串行通讯在基于DSP控制的变频调速中的应用

Application of Variable Frequency Speed Regulation Based on DSP with Serial Communication

DSP由于具有高性能和灵活可编程的优点而得到广泛的应用。本文介绍了以DSPTMS320F2812为核心控制器的异步电动机变频调速的通讯及程序设计方法,同时通过数据传送程序说明如何使用VB6.0专业版作为开发工具、并利用DSP中的SCI模块来实现DSP与PC机间的数据传递。通过实验证明该通信方案简单易行、通信稳定可靠、具有一定的通用性。

DSP has been widely used for the high performance and flexible programming ability.This paper introduces how to design the communication program of variable frequency speed regulation of asynchronous motor depending on DSP TMS320F2812 as head controller,then illuminates how to achieve communication between DSP and PC by VB 6.0 and SCI of DSP,it is provesd by many experiment that the corresponding project is a simple,steady and universal way in deal with communication.
