基于DSP的TSF控制器串行通信设计

Design of the serial communication of TSF controller based on DSP

为了满足电力电子装置日益复杂的功能要求,DSP(数字信号处理器)在其控制器中的应用日益普遍。介绍了利用TMS320F28335DSP芯片的SCI(串行通信接口)模块实现适用于RS-485总线的TSF(晶闸管投切滤波器)控制器串行数据通信方案,并使用VC++开发了相应的上位机软件。该方案可应用于多种基于DSP的电力电子控制装置与上位机间的数据交换。在实际环境下运行表明该方案简单有效、移植方便,具有较强的实用性。

In order to meet the increasingly requirements of power electronic devices＇ complex function,the application of DSP（digital signal processor） is increasingly common in controller system.This paper describes how to use the SCI（serial communication interface） module of TMS320F28335DSP to implement the TSF（Thyristor Switched Filters） controller serial data communication on RS-485 bus,and developes the corresponding host computer software based on the VC＋＋.The program can be used in data exchange between variety of DSP-based power electronic devices and the host computer.The real environment test proved that this method is simple,effective and portable convenience,has strong practicability.
