基于ZigBee技术的无线电能采集终端的设计

本文提出了一种基于ZigBee技术实现的三相电能无线采集终端的设计方案,分析了从电能测量到数据收发过程的系统工作原理。在电能测量部分,利用ADI公司的一种高精度三相电能测量IC ADE7758作为电能测量芯片,使用Microchip公司的高性能单片机PIC18LF4620作控制器。在数据收发部分采用支持IEEE802 15．4无线通信协议的ZigBee技术,用Chipcon公司的射频芯片CC2420,实现采集的电能数据的无线收发通信。该系统可以实现对三相电能的无线自动采集功能。

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.
