【監(jian)控系(xi)(xi)統】監(jian)控系(xi)(xi)統的組(zu)成 安防監(jian)控系(xi)(xi)統由哪幾部分組(zu)成

隨著科技的發展，人民生活水平的提高，人們對安全措施的要求也越來越多，監控系統在人們日常(chang)生活中接觸(chu)的(de)最多(duo)，就目前發展開看，監控(kong)(kong)系統的(de)普及也(ye)越來越廣(guang)。幾乎所有(you)高新科技都可(ke)促進其(qi)發展，尤(you)其(qi)是信(xin)息時代的(de)來臨，更為該專業發展提供(gong)契機(ji)。我們根(gen)據系統各部分功能(neng)的(de)不同，將整個安防監控(kong)(kong)系統劃分為七層——表現(xian)層、控(kong)(kong)制(zhi)層、處理層、傳(chuan)輸(shu)層、執(zhi)行(xing)層、支(zhi)撐層、采集層。

監控系統的組成——表現層

表現城是我們最直觀感受到的，它展現了整個安防監控系統的品質。如監控電視墻、監(jian)視器、高音報警(jing)喇叭(ba)、報警(jing)自動駁接電話(hua)等等都屬(shu)于這一層。

監控系統的組成——處理層

處理層(ceng)(ceng)或許該稱為音(yin)視(shi)(shi)頻(pin)(pin)處理層(ceng)(ceng)，它(ta)將(jiang)有(you)傳輸層(ceng)(ceng)送(song)過來的音(yin)視(shi)(shi)頻(pin)(pin)信號加以分配、放(fang)大(da)、分割等等處理，有(you)機的將(jiang)表現層(ceng)(ceng)與控制層(ceng)(ceng)加以連接。音(yin)視(shi)(shi)頻(pin)(pin)分配器(qi)、音(yin)視(shi)(shi)頻(pin)(pin)放(fang)大(da)器(qi)、視(shi)(shi)頻(pin)(pin)分割器(qi)、音(yin)視(shi)(shi)頻(pin)(pin)切(qie)換器(qi)等等設(she)備都(dou)屬于這一(yi)層(ceng)(ceng)。

監控系統的組成——控制層

控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)層(ceng)是(shi)(shi)(shi)整(zheng)個安(an)防監(jian)控(kong)(kong)(kong)(kong)(kong)系(xi)統(tong)(tong)的(de)核(he)(he)心(xin)，它是(shi)(shi)(shi)系(xi)統(tong)(tong)科技水(shui)平的(de)最明(ming)確體現(xian)。通(tong)(tong)常(chang)我們的(de)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)方(fang)(fang)(fang)式有(you)兩種(zhong)——模(mo)(mo)擬(ni)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)和(he)數(shu)字(zi)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)。模(mo)(mo)擬(ni)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)是(shi)(shi)(shi)早期的(de)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)方(fang)(fang)(fang)式，其控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)臺通(tong)(tong)常(chang)由控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)器(qi)(qi)或者(zhe)模(mo)(mo)擬(ni)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)矩陣構(gou)成，適用(yong)于小型局部安(an)防監(jian)控(kong)(kong)(kong)(kong)(kong)系(xi)統(tong)(tong)，這種(zhong)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)方(fang)(fang)(fang)式成本較(jiao)(jiao)低，故障率(lv)較(jiao)(jiao)小。但(dan)對于中(zhong)(zhong)大型安(an)防監(jian)控(kong)(kong)(kong)(kong)(kong)系(xi)統(tong)(tong)而(er)言，這種(zhong)方(fang)(fang)(fang)式就顯得(de)操作(zuo)(zuo)復(fu)雜且無任何價格(ge)優勢了，這時我們更為(wei)(wei)明(ming)智的(de)選擇(ze)應該是(shi)(shi)(shi)數(shu)字(zi)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)。數(shu)字(zi)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)是(shi)(shi)(shi)將(jiang)工控(kong)(kong)(kong)(kong)(kong)計(ji)算機作(zuo)(zuo)為(wei)(wei)監(jian)控(kong)(kong)(kong)(kong)(kong)系(xi)統(tong)(tong)的(de)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)核(he)(he)心(xin)，它將(jiang)復(fu)雜的(de)模(mo)(mo)擬(ni)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)操作(zuo)(zuo)變為(wei)(wei)簡單的(de)鼠標點擊操作(zuo)(zuo)，將(jiang)巨大的(de)模(mo)(mo)擬(ni)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)器(qi)(qi)堆迭縮小為(wei)(wei)一(yi)個工控(kong)(kong)(kong)(kong)(kong)計(ji)算機，將(jiang)復(fu)雜而(er)數(shu)量龐大的(de)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)電(dian)纜變為(wei)(wei)一(yi)根串(chuan)行電(dian)話線。它將(jiang)中(zhong)(zhong)遠程監(jian)控(kong)(kong)(kong)(kong)(kong)變為(wei)(wei)事實、為(wei)(wei)Internet遠程監(jian)控(kong)(kong)(kong)(kong)(kong)提供可能。但(dan)數(shu)字(zi)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)也不是(shi)(shi)(shi)那么十全十美，控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)主機的(de)價格(ge)十分昂貴(gui)、模(mo)(mo)塊浪費的(de)情況、系(xi)統(tong)(tong)可能出(chu)現(xian)全線崩(beng)潰的(de)危機、控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)較(jiao)(jiao)為(wei)(wei)滯后等等問(wen)題仍(reng)然存在。
