Title Design of Digital Frequency Meter Based on SCM

Abstract Nowadays, the digital frequency meter as a essential monitoring device for signal frequency in power system is developing to the direction of simplification, miniaturization, intelligence and multi-function。 In this paper, a full-electronic digital frequency meter is designed according to the technique target and the development requirement of the current frequency meter, combined with the traditional frequency measurement method。 The ARM kernel STM32F103ZET6 is used as the control core of meters。 The frequency measurement procedure is designed using its timer with input capture characteristics。 At the same time, the filter module, shaping module, display module and serial module and other related function modules are designed to complete the collection of the data and the processing of the signal。 In addition, the host computer processing is designed to achieve the function of displaying frequency values in a chart,which can complete the measurement of the signal frequency and the frequency fluctuation analysis。
