1、摘要隨著信息技術(shù)的飛速發(fā)展以及人們生活水平的大幅度提高,人們對(duì)住宅的需求已從追求簡(jiǎn)單的生存空間向著追求質(zhì)量、功能、服務(wù)等多重需求過(guò)渡。同時(shí),隨著人們的保護(hù)意識(shí)不斷增強(qiáng),防盜措施的緊迫性也逐漸被提上了日程,防盜報(bào)警系統(tǒng)應(yīng)運(yùn)而生。本文設(shè)計(jì)了住宅智能化中的紅外防盜報(bào)警系統(tǒng)。本系統(tǒng)以單片機(jī)89C51為核心,配以各種功能模塊,來(lái)滿足人們?nèi)粘I钪械陌踩枨?,本系統(tǒng)采用了熱釋電紅外傳感器,它的制作簡(jiǎn)單、成本低,安裝比較方便,抗干擾力強(qiáng)、靈敏度高,而且安裝較隱蔽,不易被發(fā)覺(jué)。該系統(tǒng)主要包括紅外探測(cè)電路、LCD控制電路、聲光報(bào)警電路及單片機(jī)控制電路等。自動(dòng)檢測(cè)功能由紅外探測(cè)電
2、路實(shí)現(xiàn),當(dāng)有盜賊穿過(guò)此裝置時(shí),紅外傳感器立即將檢測(cè)到的信號(hào)經(jīng)過(guò)信號(hào)處理后傳送給主機(jī)電路,由主機(jī)來(lái)判斷信號(hào)并驅(qū)動(dòng)電路報(bào)警。報(bào)警功能由揚(yáng)聲器、蜂鳴器等發(fā)聲裝置實(shí)現(xiàn),同時(shí)通過(guò)RS-485通信報(bào)警給小區(qū)警衛(wèi)。本設(shè)計(jì)通過(guò)紅外傳感器探測(cè)人體紅外線信號(hào),從而達(dá)到報(bào)警的功能,滿足了人們?nèi)粘I顚?duì)防盜報(bào)警功能的需要。關(guān)鍵詞:防盜報(bào)警,紅外探測(cè),RS-485通信,聲光報(bào)警42ABSTRACTWiththerapiddevelopmentofcommunicationtechniqueandgreatimprovementofpeople’slivingstandard,thene
