Design of wireless electrical energy meter based on ZigBee

This paper proposed a project with wireless meter for metering three-phase electdcal energy actualized by ZigBee,analyzed the work principle of system in the process of electrical energy metedng and the data receiving and transmitting.In the module of electrical energy metering,a sort of high accuracy IC for metering three-phase electrical energy,ADE7758 was used as the electrical energy metering chip,a high speed MCU PIC18LF4620,was used as the controller.In the module of data receiving and transmitting,we used the technique of ZigBee which was based on the wireless communication protocol IEEE802.15.4.The project accomplished the wireless communication of electrical energy with CC2420.The system can accomplish the wireless automatic metering function for three -phase electrical energy.
