1、黃河科技學(xué)院畢業(yè)設(shè)計(jì)第IV頁(yè)多區(qū)域紅外監(jiān)控?zé)o線報(bào)警系統(tǒng)設(shè)計(jì)摘要隨著科技的不斷發(fā)展,各系統(tǒng)間的聯(lián)系越來(lái)越緊密,對(duì)各系統(tǒng)間的數(shù)據(jù)傳遞的要求也越來(lái)越高。而隨著智能化的普及,形成了以智能化控制為主的一些外部設(shè)備控制系統(tǒng)。但是外部設(shè)備越多,連接用的線也越多,進(jìn)而給人們的生產(chǎn)生活帶來(lái)了很多的麻煩。隨著社會(huì)安全保障的需要,電子報(bào)警這門(mén)綜合技術(shù)正在不斷地發(fā)展。與此同時(shí),紅外技術(shù)已經(jīng)成為先進(jìn)科學(xué)技術(shù)的重要組成部分,用它進(jìn)行紅外探測(cè)監(jiān)控,具有良好的隱蔽性,而且其抗干擾能力強(qiáng)。本設(shè)計(jì)就是利用電路控制技術(shù)和紅外探測(cè)技術(shù)實(shí)現(xiàn)了多區(qū)域
2、的紅外監(jiān)控?zé)o線報(bào)警系統(tǒng)。本課題采用HN911作為紅外探測(cè)模塊,用VD5026/VD5027作為編/解碼芯片實(shí)現(xiàn)四通道紅外監(jiān)控?zé)o線報(bào)警系統(tǒng)。當(dāng)有物體進(jìn)入檢測(cè)范圍時(shí),發(fā)射機(jī)發(fā)出高頻無(wú)線電調(diào)幅波,接收機(jī)收到信號(hào)后發(fā)出聲、光報(bào)警。該系統(tǒng)主要由4個(gè)紅外探測(cè)發(fā)射機(jī)和1個(gè)無(wú)線聲光報(bào)警接收機(jī)組成,具有成本低、體積小、功耗低、安裝簡(jiǎn)便等特點(diǎn),能夠?yàn)闈M(mǎn)足普通對(duì)多區(qū)域控點(diǎn)報(bào)警器的需求。關(guān)鍵詞:無(wú)線收發(fā)模塊,報(bào)警系統(tǒng),VD5026VD5027,HN91黃河科技學(xué)院畢業(yè)設(shè)計(jì)第IV頁(yè)Designofmuch-channelwire
