1、南京工程學(xué)院康尼學(xué)院本科畢業(yè)設(shè)計(jì)(論文)題目:紅外無線防盜報(bào)警系統(tǒng)的設(shè)計(jì)研究專業(yè):自動(dòng)化班級(jí):K自動(dòng)化091學(xué)號(hào):240091040學(xué)生姓名:李浩千指導(dǎo)教師:陸鋒講師起迄日期:2013.2~2013.6設(shè)計(jì)地點(diǎn):實(shí)驗(yàn)樓GraduationDesign(Thesis)DesignofInfraredWirelessBurglarAlarmSystemByLIHaoqianSupervisedbyLecturer.LUFengSchoolofAutomationNanjingInstituteofTechnologyJune,2013摘要隨著社會(huì)的不斷進(jìn)步和科學(xué)技
2、術(shù)、經(jīng)濟(jì)的不斷發(fā)展,人們的生活水平得到很大的提高,對(duì)私有財(cái)產(chǎn)的保護(hù)意識(shí)在不斷地增強(qiáng),因而對(duì)防盜措施提出了新的要求,而紅外技術(shù)已經(jīng)相當(dāng)成熟,本設(shè)計(jì)就是為了滿足現(xiàn)代防盜的需求基于紅外感應(yīng)和紅外無線傳輸和單片機(jī)結(jié)合的報(bào)警系統(tǒng)。本設(shè)計(jì)采用的是AT89C51單片機(jī)控制,接收信號(hào)經(jīng)過處理后選擇報(bào)警蜂鳴器和警示燈工作,它具有體積小,成本低等優(yōu)點(diǎn),很適合用于報(bào)警信號(hào)的接收和處理;傳感器部分使用的是熱釋電紅外傳感器,配合菲涅爾透鏡,它們配合可以非接觸式的測出人體的紅外信號(hào)并將其轉(zhuǎn)變?yōu)殡妷盒盘?hào),傳送給單片機(jī)處理,它具有體積小,靈敏度高,安裝方便,安全可靠等優(yōu)點(diǎn);本設(shè)計(jì)中傳感器與單
3、片機(jī)之間的無線傳輸是通過PT2262和PT2272兩塊芯片來實(shí)現(xiàn)的,也是基于紅外技術(shù)完成的,過程穩(wěn)定可靠。關(guān)鍵詞:紅外;無線;單片機(jī);報(bào)警器ABSTRACTWiththesocialprogressandscienceandtechnology,theeconomycontinuestodevelop,thepeople'slivingstandardhasbeengreatlyimproved,theawarenessoftheprotectionofprivatepropertyisconstantlyenhanced,andthusthesecurity
