摘要
提出了一种基于F2812的数字信号处理器实现数据采集处理的解决方案。将TMS320F2812 DSP处理器与MAX125 A/D转换芯片相结合,通过CPLD来实现组合逻辑和外设电路的地址译码,设计了系统的硬件结构和软件流程,并编写了DSP数据采集处理程序。该系统被应用在电能质量监测上,实现对三相电压、电流的数据采集和计算处理,最后通过测试得到电网电能质量的各项指标,取得了较好的效果,实用性强,可靠性高,具有很好的应用和发展前景。
The paper introduced a solution for implementing data acquisition and processing by F2812 DSP.The system is mainly made up of DSP processor(TMS320F2812) and MAX125 A/D converter chip,and implemented digital logic and address encode of peripheral hardware by CPLD.Designed the hardware structure and software flow,and wrote the DSP data acquisition process program.The system has been applied for power quality monitor which acquires and processes data of voltage and current,and the results are satisfied through...
