1、畢業(yè)設(shè)計(jì)（論文）紅外報(bào)警器的設(shè)計(jì)姓名：學(xué)號(hào)：2010132專業(yè)：電子信息工程系別：通信工程系指導(dǎo)教師：41摘要隨著社會(huì)的不斷進(jìn)步和科學(xué)技術(shù)、經(jīng)濟(jì)的不斷發(fā)展，人們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)在不斷的增強(qiáng)，因而對(duì)防盜措施提出了新的要求。本設(shè)計(jì)就是為了滿足現(xiàn)代住宅防盜的需要而設(shè)計(jì)的家庭式電子防盜系統(tǒng)。目前市面上裝備主要有壓力觸發(fā)式防盜報(bào)警器、開關(guān)電子防盜報(bào)警器和壓力遮光觸發(fā)式防盜報(bào)警器等各種報(bào)警器，但這幾種比較常見的報(bào)警器都存在一些缺點(diǎn)。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，而且防盜性能比較穩(wěn)定，抗干擾能力強(qiáng)、靈敏度高、安全
2、可靠。這種防盜器安裝隱蔽，不易被盜賊發(fā)現(xiàn)。同時(shí)它的信號(hào)經(jīng)過(guò)單片機(jī)系統(tǒng)處理后方便和ＰＣ機(jī)通信，便于多用戶統(tǒng)一管理。本設(shè)計(jì)包括硬件和軟件設(shè)計(jì)兩個(gè)部分。硬件部分包括單片機(jī)控制電路、紅外探頭電路、驅(qū)動(dòng)執(zhí)行報(bào)警電路、LED控制電路等部分組成。處理器采用51系列單片機(jī)AT89S51。整個(gè)系統(tǒng)是在系統(tǒng)軟件控制下工作的。系統(tǒng)程序可以劃分為以下幾個(gè)模塊： 數(shù)據(jù)采集、鍵盤控制、報(bào)警和顯示等子函數(shù)。關(guān)鍵詞：?jiǎn)纹瑱C(jī)；紅外傳感器；數(shù)據(jù)采集；報(bào)警電路41ABSTRACTAlongwithsociety'sunceasingprogressandscienceandtechnology,ec
