Study on Electrical Automation with Design of the Constant-Precision Frequency Meter Based on MCU and CPLD

Abstract:

According to the principle of constant-precision frequency measurement in the field of electrical automation, the relationship of frequency measurement precision and gate time is analyzed. And the constant-precision frequency meter based on MCU and CPLD is designed in this paper. It can keep the relative error being 0.0001% constantly when frequency measuring within the range of 0.1Hz to 1MHz. Its simulation results by MUX+PLUS is presented.
