摘  要:
Energy parameter monitoring instrument that adopted the mode of A/D+MCU widely has the defects of complex circuit,great amount of computation of CPU,and low real-time capacity,and also has imperfect of the rural power network monitoring system,so a new integrated electrical power monitoring instrument for rural power network is developed based on high precision three-phase energy metering IC ATT7022B and high ant-jamming AVR single chip Mega128 as MCU.The detailed hardware circuit diagram and software flow chart are presented in the paper,meanwhile the data-processing of energy metering chip and the calibration method are mainly discussed.The practical running results have proved that this measuring instrument has high measuring accuracy,strong real-time capacity,favorable human-machine interface and powerful communication capabilities.
