    Abstract: On the basis of discrete Fourier transform AC sampling algorithm, this paper proposed a method of software frequency measurement. This method not only retained the advantages of the filtering ability of discrete Fourier transform algorithm, but also simplified the circuit of frequency measurement. This paper described the software frequency measurement principle, making a deduction for the formula of various AC parameters and giving an AC parameters acquisition implementation plan based on the STM32F103ZE processor and the AD7606 analog-to-digital conversion chip. The flowchart of software design was discussed. The test verifies the applicability of this implementation plan.
