基于ATmega系列單片機的電力檢測設備

基于ATmega系列單片機的電力檢測設備:摘要：電力檢測設備的精確灝l量及實時傳送對電力監(jiān)控系統(tǒng)的正常工作有著重要的意義。Atmega系列是AVR 單片機的高檔產(chǎn)品．
其具有高性能、低功耗的微控制器，超強的接口功能及具有自編程能力的程序存儲器，非常適合于需要遠程控制和現(xiàn)場升級的應用領(lǐng)域通過對Atmega系列單片機的設計而實現(xiàn)的電力檢測設備，能夠快速、精確的進行在線測量，并將測量數(shù)據(jù)以4~20mA的形式實時輸出進行遠程控制，產(chǎn)品滿足當前電力監(jiān)控系統(tǒng)的需求，具有較大的市場前景，其設計思路也可為其他檢測設備的開發(fā)提供一定的參考。
