很多人在購買了紅外線報警器之后，不知(zhi)道(dao)怎么(me)去安裝，看(kan)了說明書一遍又一遍，卻始終(zhong)是不得要領。今天小(xiao)編(bian)就(jiu)來介紹紅外線報警(jing)器(qi)原理(li)及安裝方法，讓(rang)大家增長一下關于(yu)紅外線報警(jing)器(qi)的(de)知(zhi)識吧，下面就(jiu)讓(rang)一起(qi)裝修網(wang)小(xiao)編(bian)來帶(dai)您(nin)來詳細(xi)的(de)了解(jie)一下。

一、紅外線報警器原理

紅外(wai)報(bao)(bao)警器分(fen)為(wei)主動(dong)紅外(wai)報(bao)(bao)警和被(bei)動(dong)紅外(wai)報(bao)(bao)警，下面我(wo)們就分(fen)別(bie)來(lai)看(kan)看(kan)主動(dong)紅外(wai)報(bao)(bao)警和被(bei)動(dong)紅外(wai)報(bao)(bao)警的工作原理分(fen)別(bie)為(wei)何(he)：

主(zhu)動紅(hong)(hong)(hong)外(wai)(wai)(wai)(wai)入侵報警(jing)器(qi)(qi)(qi)是(shi)(shi)由發(fa)(fa)(fa)射(she)(she)(she)機(ji)和接(jie)收(shou)(shou)(shou)機(ji)組(zu)成(cheng)(cheng)，發(fa)(fa)(fa)射(she)(she)(she)機(ji)是(shi)(shi)由電(dian)源、發(fa)(fa)(fa)光(guang)(guang)(guang)(guang)(guang)(guang)源和光(guang)(guang)(guang)(guang)(guang)(guang)學系(xi)統組(zu)成(cheng)(cheng)，接(jie)收(shou)(shou)(shou)機(ji)是(shi)(shi)由光(guang)(guang)(guang)(guang)(guang)(guang)學系(xi)統、光(guang)(guang)(guang)(guang)(guang)(guang)電(dian)傳(chuan)感(gan)器(qi)(qi)(qi)、放(fang)大(da)器(qi)(qi)(qi)、信(xin)(xin)號(hao)處(chu)理(li)器(qi)(qi)(qi)等(deng)部分組(zu)成(cheng)(cheng)。主(zhu)動紅(hong)(hong)(hong)外(wai)(wai)(wai)(wai)報警(jing)器(qi)(qi)(qi)是(shi)(shi)一(yi)種紅(hong)(hong)(hong)外(wai)(wai)(wai)(wai)線(xian)(xian)(xian)光(guang)(guang)(guang)(guang)(guang)(guang)束(shu)遮(zhe)擋型報警(jing)器(qi)(qi)(qi)，發(fa)(fa)(fa)射(she)(she)(she)機(ji)中的(de)(de)紅(hong)(hong)(hong)外(wai)(wai)(wai)(wai)發(fa)(fa)(fa)光(guang)(guang)(guang)(guang)(guang)(guang)二極管(guan)在(zai)電(dian)源的(de)(de)激發(fa)(fa)(fa)下(xia)，發(fa)(fa)(fa)出一(yi)束(shu)經(jing)過調(diao)制的(de)(de)紅(hong)(hong)(hong)外(wai)(wai)(wai)(wai)光(guang)(guang)(guang)(guang)(guang)(guang)束(shu)(此光(guang)(guang)(guang)(guang)(guang)(guang)束(shu)的(de)(de)波(bo)長約在(zai)0.8～0.95微米之間)，經(jing)過光(guang)(guang)(guang)(guang)(guang)(guang)學系(xi)統的(de)(de)作用變成(cheng)(cheng)平行光(guang)(guang)(guang)(guang)(guang)(guang)發(fa)(fa)(fa)射(she)(she)(she)出去。此光(guang)(guang)(guang)(guang)(guang)(guang)束(shu)被(bei)接(jie)收(shou)(shou)(shou)機(ji)接(jie)收(shou)(shou)(shou)，由接(jie)收(shou)(shou)(shou)機(ji)中的(de)(de)紅(hong)(hong)(hong)外(wai)(wai)(wai)(wai)光(guang)(guang)(guang)(guang)(guang)(guang)電(dian)傳(chuan)感(gan)器(qi)(qi)(qi)把(ba)光(guang)(guang)(guang)(guang)(guang)(guang)信(xin)(xin)號(hao)轉換成(cheng)(cheng)信(xin)(xin)號(hao)，經(jing)過電(dian)路(lu)處(chu)理(li)后傳(chuan)給報警(jing)控制器(qi)(qi)(qi)。由發(fa)(fa)(fa)射(she)(she)(she)機(ji)發(fa)(fa)(fa)射(she)(she)(she)出的(de)(de)紅(hong)(hong)(hong)外(wai)(wai)(wai)(wai)線(xian)(xian)(xian)經(jing)過防(fang)(fang)范區到達接(jie)收(shou)(shou)(shou)機(ji)，構成(cheng)(cheng)了一(yi)條警(jing)戒線(xian)(xian)(xian)。正常(chang)情況下(xia)，接(jie)收(shou)(shou)(shou)機(ji)收(shou)(shou)(shou)到的(de)(de)是(shi)(shi)一(yi)個穩定(ding)的(de)(de)光(guang)(guang)(guang)(guang)(guang)(guang)信(xin)(xin)號(hao)，當(dang)(dang)有人入侵該警(jing)戒線(xian)(xian)(xian)時，紅(hong)(hong)(hong)外(wai)(wai)(wai)(wai)光(guang)(guang)(guang)(guang)(guang)(guang)束(shu)被(bei)遮(zhe)擋，接(jie)收(shou)(shou)(shou)機(ji)收(shou)(shou)(shou)到的(de)(de)紅(hong)(hong)(hong)外(wai)(wai)(wai)(wai)信(xin)(xin)號(hao)發(fa)(fa)(fa)生(sheng)變化(hua)，提取這(zhe)一(yi)變化(hua)，經(jing)放(fang)大(da)和適當(dang)(dang)處(chu)理(li)，控制器(qi)(qi)(qi)發(fa)(fa)(fa)出的(de)(de)報警(jing)信(xin)(xin)號(hao)。目前(qian)此類(lei)報警(jing)器(qi)(qi)(qi)有二光(guang)(guang)(guang)(guang)(guang)(guang)束(shu)、三(san)光(guang)(guang)(guang)(guang)(guang)(guang)束(shu)還有多光(guang)(guang)(guang)(guang)(guang)(guang)束(shu)的(de)(de)紅(hong)(hong)(hong)外(wai)(wai)(wai)(wai)柵(zha)欄等(deng)。一(yi)般應用在(zai)周界(jie)防(fang)(fang)范居(ju)多，最(zui)大(da)的(de)(de)優(you)點就是(shi)(shi)防(fang)(fang)范距離遠，能達到被(bei)動紅(hong)(hong)(hong)外(wai)(wai)(wai)(wai)的(de)(de)十(shi)倍(bei)以上探(tan)測距離。

被動(dong)紅(hong)(hong)(hong)(hong)外(wai)(wai)報(bao)警器(qi)主要(yao)是根據外(wai)(wai)界(jie)紅(hong)(hong)(hong)(hong)外(wai)(wai)能量的(de)(de)(de)變化來判斷(duan)是否(fou)有人(ren)在移(yi)動(dong)。人(ren)體(ti)(ti)(ti)的(de)(de)(de)紅(hong)(hong)(hong)(hong)外(wai)(wai)能量與環境有差別，當人(ren)通過探(tan)測(ce)區域時(shi)，報(bao)警器(qi)收集到的(de)(de)(de)這(zhe)個不同的(de)(de)(de)紅(hong)(hong)(hong)(hong)外(wai)(wai)能量的(de)(de)(de)位置變化，進(jin)而通過分析(xi)發(fa)(fa)出報(bao)警。人(ren)體(ti)(ti)(ti)都有恒定的(de)(de)(de)體(ti)(ti)(ti)溫(wen)，一般(ban)在37度左(zuo)右(you)(you)，會發(fa)(fa)出特定波(bo)長10μm左(zuo)右(you)(you)的(de)(de)(de)紅(hong)(hong)(hong)(hong)外(wai)(wai)線，被動(dong)紅(hong)(hong)(hong)(hong)外(wai)(wai)報(bao)警器(qi)就是靠(kao)探(tan)測(ce)人(ren)體(ti)(ti)(ti)發(fa)(fa)射(she)的(de)(de)(de)10μm左(zuo)右(you)(you)的(de)(de)(de)紅(hong)(hong)(hong)(hong)外(wai)(wai)線而進(jin)行工(gong)作的(de)(de)(de)。人(ren)體(ti)(ti)(ti)發(fa)(fa)射(she)的(de)(de)(de)10μm左(zuo)右(you)(you)的(de)(de)(de)紅(hong)(hong)(hong)(hong)外(wai)(wai)線通過菲(fei)涅爾(er)濾光片(pian)增(zeng)強后(hou)(hou)聚(ju)集到紅(hong)(hong)(hong)(hong)外(wai)(wai)感(gan)應(ying)源(yuan)上。紅(hong)(hong)(hong)(hong)外(wai)(wai)感(gan)應(ying)源(yuan)通常采用熱釋(shi)電(dian)元(yuan)件，這(zhe)種元(yuan)件在接(jie)收到人(ren)體(ti)(ti)(ti)紅(hong)(hong)(hong)(hong)外(wai)(wai)輻(fu)射(she)溫(wen)度發(fa)(fa)生變化時(shi)就會失去電(dian)荷(he)平衡，向外(wai)(wai)釋(shi)放(fang)電(dian)荷(he)，后(hou)(hou)續電(dian)路經檢測(ce)處(chu)理后(hou)(hou)就能產(chan)生報(bao)警信號。

1.被動(dong)紅外報警器是以探測人(ren)體(ti)輻(fu)射為目標的，所以熱釋電元件(jian)對波長為10μm左(zuo)右的紅外輻(fu)射必(bi)須非常敏(min)感。

2.為了僅僅對(dui)人體的(de)紅外輻(fu)射敏感(gan)，在(zai)它(ta)的(de)輻(fu)射照(zhao)面通常覆蓋有(you)特殊的(de)菲(fei)涅(nie)爾濾光片，使環境的(de)干擾(rao)受到明顯(xian)的(de)控制作用。

3.其傳感器包含兩(liang)個互相(xiang)串聯(lian)或并聯(lian)的熱釋(shi)電(dian)元件。而且制成(cheng)的兩(liang)個電(dian)極化方向(xiang)正好相(xiang)反，環境背景(jing)輻射對兩(liang)個熱釋(shi)元件幾(ji)乎具有(you)相(xiang)同的作用，使其產生釋(shi)電(dian)效應相(xiang)互抵(di)消，于(yu)是報警器無信號(hao)輸出。

4. 一旦(dan)人(ren)侵(qin)入探(tan)測區域內，人(ren)體(ti)紅(hong)外輻射通(tong)過部分(fen)鏡面(mian)聚焦，并被熱(re)釋(shi)電(dian)元(yuan)接收(shou)，但是兩(liang)片熱(re)釋(shi)電(dian)元(yuan)接收(shou)到的熱(re)量不(bu)同，熱(re)釋(shi)電(dian)也不(bu)同不(bu)能(neng)抵消，經信號處理(li)而報警。

二、家用紅外線報警器安裝

在安裝紅外線報(bao)警(jing)(jing)器之前，首先應把報(bao)警(jing)(jing)主機通電(dian)放在固定位置(zhi)，把報(bao)警(jing)(jing)探(tan)頭掛在約2米(mi)高的(de)地(di)方，使其向前下方傾斜(xie)，以(yi)獲得(de)較高的(de)靈敏度。接通電(dian)源，經過1分鐘左右的(de)延(yan)時后，報(bao)警(jing)(jing)器進入警(jing)(jing)戒狀(zhuang)態(tai)，這(zhe)時，若有人進入監控區(qu)，即刻報(bao)警(jing)(jing)。報(bao)警(jing)(jing)約1分鐘，自(zi)動(dong)停止。然后重新處于警(jing)(jing)戒狀(zhuang)態(tai)。

當主人進入(ru)時，首(shou)先按一(yi)下遙控器(qi)(qi)上(shang)的關(guan)機(ji)鍵，隨著紅(hong)外線報(bao)(bao)警(jing)器(qi)(qi)一(yi)聲(sheng)“嘀(di)”響，即關(guan)閉了報(bao)(bao)警(jing)器(qi)(qi)，進入(ru)警(jing)戒區也不再報(bao)(bao)警(jing)。當主人離開警(jing)戒區后，按一(yi)下開機(ji)鍵，隨一(yi)聲(sheng)“嘀(di)”響，報(bao)(bao)警(jing)器(qi)(qi)重(zhong)處(chu)于(yu)警(jing)戒狀態。

遇到緊(jin)急(ji)情(qing)況，按一下(xia)緊(jin)急(ji)報警鍵(jian)，紅(hong)外(wai)線(xian)報警器即緊(jin)急(ji)報警。

紅外線報警器(qi)內設有高，中，低(di)三檔靈敏度調整，用戶可根(gen)據需要自行調整。

以上就是小編今天為大家介紹的關于紅外線報警器的(de)基本情況和(he)介紹，相信朋友們(men)也都(dou)有了一(yi)定的(de)了解，希望這篇文章可(ke)(ke)以(yi)幫助到你們(men)喔(wo)。大家也可(ke)(ke)以(yi)登錄到一(yi)起裝修網查看訂閱更多相關(guan)內容和(he)資(zi)訊。
