摘　　要：本文设计了基于Cortex-M3的三相交流电压相序检测仪。首先采用软件同步采样方法对三相交流电压进行等间隔采样,再由主控芯片STM32F103对采样数据进行数字信号处理,然后采用FFT算法和相序检测算法实现对相序的检测,并将结果显示出来,最后从软件设计和硬件设计等方面进行总体设计,并通过结果测量和分析验证该设计的可行性。This paper designs a phase sequence detector for three-phase ac voltage based on Cortex-M3. The device uses the synchronous sampling method for interval sampling, the main control chip STM32F103 for digital signal processing, and the FFT algorithm and phase sequence detection algorithm for detecting the phase sequence, and finally displays the results. The paper designs the software and hardware, and validates the design through measurements and analyses.
