Abstract
With the continuous development of power technology, real-time and accurate monitoring of power parameters in the power grid to ensure safe and stable operation of power transmission has become a hot topic of research today. The power parameter measuring instrument can realize multifunctional detection, the overall design and the combination of hardware technology and software technology, connect the mobile phone APP and hardware through WiFi transmission, and display the transmission data in real time on the smart phone terminal. Select STM32F103 as the microprocessor, adopt software synchronous sampling method, control 16-bit high-precision AD conversion chip ADS8556 for AD sampling, and then process the data by discretization method and FFT harmonic analysis algorithm, and finally send the data to The display on the Android mobile phone can realize the measurement of single-phase AC voltage and current RMS value, active power, power factor, frequency and other power parameters, and has a harmonic analysis function. The measurement data is displayed by the smartphone terminal. Tested by a test platform composed of BD-3D multi-function calibrator, the results show that its performance indicators meet the design requirements.
