基于ATmega系列單片機(jī)的電力檢測設(shè)備

基于ATmega系列單片機(jī)的電力檢測設(shè)備:摘要：電力檢測設(shè)備的精確灝l量及實(shí)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(jī)的高檔產(chǎn)品．
其具有高性能、低功耗的微控制器，超強(qiáng)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(yuǎn)程控制和現(xiàn)場升級的應(yīng)用領(lǐng)域通過對Atmega系列單片機(jī)的設(shè)計而實(shí)現(xiàn)的電力檢測設(shè)備，能夠快速、精確的進(jìn)行在線測量，并將測量數(shù)據(jù)以4~20mA的形式實(shí)時輸出進(jìn)行遠(yuǎn)程控制，產(chǎn)品滿足當(dāng)前電力監(jiān)控系統(tǒng)的需求，具有較大的市場前景，其設(shè)計思路也可為其他檢測設(shè)備的開發(fā)提供一定的參考。
