摘　　要：TMS320F28335是32位浮点DSP(数字信号处理器)芯片,在电力电子装置中的应用日益广泛。本文介绍了利用DSP芯片的SCI(串行通信接口)模块与Visual Basic中的MSComm控件在电力电子控制装置中实现符合IEC60870-5-101规范的串行数据通信方案。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,便于系统的开发与调试,具有较强的实用性。TMS320F28335, a 32-bit floating-point DSP （digital signal processor） chip, is more widely used in power electronic control devices. This paper describe a serial data communications program which combines the SCI （serial communication interface） module of DSP and the MSComm control of Visual Basic could easily achieve the transmit data under the protocol of lEC60870-5-101 in power electronic control devices. It can be used in data exchange between variety of DSP-based power electronic devices and the host computer. And the real environment test proved that this method is simple, effective and portable convenience, facilitate the development and debugging of DSP-based Dower electronic control devices, has strong practicability.
