Design and Implementation of a Multi-functional Electric Meter Based on MCU
In order to help the large electricity users with energy saving management,a new design of portable multi-functional electric meter based on advanced MCU is proposed in this paper.The program design process for MCU and interface circuits between MCU and peripheral devices are described in detail in the paper.High precision MAX1320 is used for power quality data synchronous acquisition.And the MCU is used for calculation and analysis.The data are stored in large capacity storage device and displayed in the LCD.The testing results show that the design is feasible and that the device realizes on-line monitoring of many electrical parameters.
