1、本科學生畢業(yè)論文(設(shè)計)題目基于單片機的聲光雙控開關(guān)設(shè)計系別物理與電子科學系專業(yè)電氣工程及其自動化學生姓名武春東指導(dǎo)教師陳新河職稱講師論文字數(shù)5788完成日期:2011年5月27日基于單片機的聲光雙控開關(guān)的設(shè)計武春東(巢湖學院物理與電子科學系,安徽巢湖238000)摘要:該設(shè)計主要介紹的是關(guān)于聲光控的電路設(shè)計。聲光控是通過光敏電阻來實現(xiàn)的,當光敏電阻在背光的的時候燈就會慢慢的熄滅,即這時也是人走過了的時候。在有的電路中這種原理也可以通過聲音的振動來實現(xiàn),當人走過是只需用手輕排一下燈就會自動的亮,人離開
2、后又熄滅。這樣就給路人提供了相應(yīng)的方便,同時,也達到了節(jié)電和節(jié)能的目的;延長燈的壽命。在實際生活中節(jié)電節(jié)能,能夠?qū)崿F(xiàn)更多的自動化。在本設(shè)計中介紹了聲光控路燈控制器的組成、性能,適用范圍及工作原理,給出各電路原理圖及元件參數(shù)選擇,節(jié)電效果十分明顯,同時也大大減少了維修量、節(jié)約了資金,使用效果良好。白天光照好,不管過路者發(fā)出多大聲音,燈泡都不會發(fā)亮。夜晚光暗,電路的拾音器只要檢測到有碎發(fā)聲響,就會自動亮為行人照明,過數(shù)十秒后又自動熄滅,節(jié)能節(jié)電。關(guān)鍵詞:自動控制;節(jié)能;光電開關(guān);聲控電路;光控電路;Bas
