1、本科畢業(yè)論文題目紅外防盜報(bào)警系統(tǒng)設(shè)計(jì)學(xué)科專(zhuān)業(yè):班級(jí):姓名:指導(dǎo)教師:指導(dǎo)教師職稱(chēng):論文提交日期:論文答辯日期:摘要現(xiàn)在人們對(duì)自己所處環(huán)境的安全要求就越來(lái)越高,特別是家居安全,不得不時(shí)刻留意不速之客的光顧?,F(xiàn)在許多小區(qū)都有著保安看管,但在一些農(nóng)村就沒(méi)有這些設(shè)施了,于是,許多家庭都安裝了報(bào)警系統(tǒng),這有效的保護(hù)了大家的財(cái)產(chǎn)安全。我設(shè)計(jì)的報(bào)警系統(tǒng)的主要功能是,因?yàn)槿梭w會(huì)發(fā)出紅外線,利用熱釋電紅外傳感器探測(cè)到人體發(fā)出的紅外線而產(chǎn)生報(bào)警的功能。我的設(shè)計(jì)是紅外報(bào)警防盜系統(tǒng),由于紅外線是不可見(jiàn)光,隱蔽性能良好,因此在防盜、警戒等安保裝置中被廣泛應(yīng)
2、用[1]。而本設(shè)計(jì)的電路包括硬件和軟件兩個(gè)部分。硬件部分包括紅外感應(yīng)部分與單片機(jī)控制部分,整個(gè)系統(tǒng)電路可劃分為:電源部分、按鍵控制部分、復(fù)位電路部分、單片機(jī)控制電路,單片機(jī)部分使用51型STC89C52單片機(jī),而單片機(jī)控制由最小系統(tǒng)和指示燈電路、報(bào)警電路等子系統(tǒng)組成。當(dāng)元件焊接完畢,進(jìn)行系統(tǒng)調(diào)試,調(diào)試成功后,按下開(kāi)關(guān),然后按下布防按鍵,進(jìn)入布防狀態(tài),當(dāng)有人員經(jīng)過(guò)探測(cè)區(qū)域時(shí),由熱釋電紅外傳感器感應(yīng)后,蜂鳴器發(fā)生報(bào)警,達(dá)到本設(shè)計(jì)的目的。此設(shè)計(jì)的優(yōu)點(diǎn)是制作成本不高,探測(cè)時(shí)靈敏度高,控制的范圍廣,易于隱藏不易發(fā)現(xiàn),安裝方便,便于普通市民使
