Design and Implementation of Three-phase Electric Parameter Acquisition Module Based on STM32F103 and ATT7022E in Intelligent Street Light Control System

摘要

To meet the need of electric power parameter acquisition in intelligent street light control system, STM32F103 as main control chip, ATT7022E for electric energy metering chip, three-phase power parameter acquisition module is designed. This module has the instantaneous voltage and current, active and reactive power, power factor and so on electric parameter acquisition, storage and display function, also uploads data to host computer through the 485 bus.
