一、紅外感應水龍頭是開環還是閉環

紅外感(gan)應水龍(long)頭是閉環系統(tong)，因為(wei)它(ta)直接檢(jian)測(ce)使(shi)用情況，進而控制(zhi)水龍(long)頭的工(gong)作。

感應水龍頭是通過紅(hong)外(wai)線(xian)(xian)(xian)(xian)(xian)反射(she)原理，當人體(ti)的(de)手放(fang)在水(shui)龍頭(tou)的(de)紅(hong)外(wai)線(xian)(xian)(xian)(xian)(xian)區域內(nei)(nei)(nei)，紅(hong)外(wai)線(xian)(xian)(xian)(xian)(xian)發射(she)管發出(chu)的(de)紅(hong)外(wai)線(xian)(xian)(xian)(xian)(xian)由于人體(ti)手的(de)摭擋反射(she)到紅(hong)外(wai)線(xian)(xian)(xian)(xian)(xian)接收管，通過集成線(xian)(xian)(xian)(xian)(xian)路(lu)內(nei)(nei)(nei)的(de)微電(dian)腦(nao)處理后的(de)信號(hao)發送給脈沖(chong)電(dian)磁閥(fa)，電(dian)磁閥(fa)接受信號(hao)后按指定(ding)的(de)指令打開閥(fa)芯來控(kong)制(zhi)水(shui)龍頭(tou)出(chu)水(shui)；當人體(ti)的(de)手離開紅(hong)外(wai)線(xian)(xian)(xian)(xian)(xian)感(gan)應范圍，電(dian)磁閥(fa)沒有接受信號(hao)，電(dian)磁閥(fa)閥(fa)芯則通過內(nei)(nei)(nei)部(bu)的(de)彈簧進(jin)行復位(wei)來控(kong)制(zhi)水(shui)龍頭(tou)的(de)關(guan)水(shui)。

二、紅外感應水龍頭的水流控制屬于手動控制嗎

紅外感應水龍(long)頭的水流控(kong)(kong)制不(bu)屬(shu)于(yu)手動控(kong)(kong)制。

手(shou)動(dong)(dong)控制是(shi)指通(tong)過直接的(de)人工(gong)(gong)操作來(lai)控制事物的(de)工(gong)(gong)作狀態，如手(shou)動(dong)(dong)開關等。而自(zi)動(dong)(dong)感(gan)應控制則是(shi)通(tong)過對(dui)周圍環境(jing)的(de)感(gan)知，自(zi)動(dong)(dong)地(di)實現控制動(dong)(dong)作，不需要人工(gong)(gong)干預(yu)。

紅外(wai)感應(ying)水龍頭采用紅外(wai)傳感器(qi)技術，當(dang)有手(shou)或物體靠近水龍頭時，紅外(wai)線(xian)就(jiu)會被反(fan)射回來(lai)，被接收器(qi)接收，然后傳送到芯片進行(xing)處(chu)理，芯片識別到信號后就(jiu)會控(kong)(kong)制水閥打開(kai)或關閉，從而(er)實現控(kong)(kong)制水流的作用。

相比于(yu)手動控(kong)(kong)制，紅外感(gan)應水(shui)(shui)(shui)龍頭(tou)具有(you)(you)很(hen)多優點，例如可以更加精準地控(kong)(kong)制水(shui)(shui)(shui)流，避免(mian)浪費水(shui)(shui)(shui)資源，節約用水(shui)(shui)(shui)成本；同時還可以避免(mian)交(jiao)叉感(gan)染，保(bao)證衛生，有(you)(you)效(xiao)預防細菌傳播(bo)；還能(neng)夠(gou)提高(gao)使用體驗和方便性(xing)，尤(you)其適用于(yu)公共場所等高(gao)頻使用場景。
