Design and Implementation of New Multi-functional Intelligent Single Phase Meters

摘要：

　　Because the reasons of only reached part intelligent of existing energy meter and the difficulty of hardware upgrades,we propose a new design that is a modular single-phase multi-rate smart electronic meter based on MSP430 low-power single-chip.We used AD7755 as a dedicated power measurement chip to ensure the accuracy of the measuring pulse.In order to improve the reliability and usefulness of the electric meter,we have used the clock circuit,data storage circuit,display drive circuit,three kinds of communication circuits,and anti-tamper technology.Through making use of it,The multifunction smart meter is proved that it has a character of stable performance,accurate measurement.It is full compliance with national design specifications of 1EC62053-22 and the active energy error met the accuracy requirements of class 0.5S.
