【監(jian)控系統(tong)】監(jian)控系統(tong)的(de)組(zu)成 安防監(jian)控系統(tong)由哪(na)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(sheng)活中接觸(chu)的(de)最多(duo)，就目前發展開看，監控(kong)系(xi)(xi)統的(de)普(pu)及也(ye)越來(lai)越廣(guang)。幾(ji)乎所有高(gao)新科(ke)技都可促進其發展，尤其是(shi)信息(xi)時代的(de)來(lai)臨，更(geng)為(wei)該(gai)專業發展提供契機。我們根(gen)據系(xi)(xi)統各部分功能的(de)不同，將(jiang)整個安防監控(kong)系(xi)(xi)統劃(hua)分為(wei)七層(ceng)——表現層(ceng)、控(kong)制層(ceng)、處理層(ceng)、傳輸(shu)層(ceng)、執行層(ceng)、支撐(cheng)層(ceng)、采集層(ceng)。

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(yin)報警(jing)喇叭、報警(jing)自(zi)動駁接電話等(deng)等(deng)都屬于這(zhe)一層。

監控系統的組成——處理層

處理層(ceng)(ceng)或許(xu)該稱為音視(shi)頻(pin)(pin)處理層(ceng)(ceng)，它將(jiang)有傳輸層(ceng)(ceng)送(song)過來的(de)音視(shi)頻(pin)(pin)信號加(jia)以(yi)分(fen)(fen)配(pei)(pei)、放大、分(fen)(fen)割等(deng)等(deng)處理，有機的(de)將(jiang)表現(xian)層(ceng)(ceng)與控(kong)制層(ceng)(ceng)加(jia)以(yi)連接。音視(shi)頻(pin)(pin)分(fen)(fen)配(pei)(pei)器(qi)、音視(shi)頻(pin)(pin)放大器(qi)、視(shi)頻(pin)(pin)分(fen)(fen)割器(qi)、音視(shi)頻(pin)(pin)切(qie)換器(qi)等(deng)等(deng)設備都(dou)屬(shu)于這一層(ceng)(ceng)。

監控系統的組成——控制層

控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)層是(shi)(shi)(shi)(shi)整個(ge)安防監(jian)控(kong)(kong)(kong)(kong)(kong)(kong)系(xi)統(tong)(tong)的(de)(de)(de)核(he)心，它(ta)是(shi)(shi)(shi)(shi)系(xi)統(tong)(tong)科技水平的(de)(de)(de)最明確體現。通常(chang)我們(men)的(de)(de)(de)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)方(fang)(fang)式(shi)有兩種(zhong)(zhong)——模(mo)(mo)(mo)擬(ni)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)和數(shu)字(zi)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)。模(mo)(mo)(mo)擬(ni)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)是(shi)(shi)(shi)(shi)早期的(de)(de)(de)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)方(fang)(fang)式(shi)，其控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)臺通常(chang)由控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)器或(huo)者模(mo)(mo)(mo)擬(ni)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)矩陣構成(cheng)(cheng)，適用于小型局部安防監(jian)控(kong)(kong)(kong)(kong)(kong)(kong)系(xi)統(tong)(tong)，這種(zhong)(zhong)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)方(fang)(fang)式(shi)成(cheng)(cheng)本(ben)較低，故障(zhang)率較小。但對于中大(da)型安防監(jian)控(kong)(kong)(kong)(kong)(kong)(kong)系(xi)統(tong)(tong)而言，這種(zhong)(zhong)方(fang)(fang)式(shi)就顯得操(cao)作(zuo)(zuo)復雜且(qie)無(wu)任何價格優勢(shi)了，這時我們(men)更為(wei)明智的(de)(de)(de)選擇應該是(shi)(shi)(shi)(shi)數(shu)字(zi)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)。數(shu)字(zi)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)是(shi)(shi)(shi)(shi)將(jiang)工控(kong)(kong)(kong)(kong)(kong)(kong)計(ji)算機作(zuo)(zuo)為(wei)監(jian)控(kong)(kong)(kong)(kong)(kong)(kong)系(xi)統(tong)(tong)的(de)(de)(de)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)核(he)心，它(ta)將(jiang)復雜的(de)(de)(de)模(mo)(mo)(mo)擬(ni)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)操(cao)作(zuo)(zuo)變為(wei)簡單的(de)(de)(de)鼠標點擊操(cao)作(zuo)(zuo)，將(jiang)巨大(da)的(de)(de)(de)模(mo)(mo)(mo)擬(ni)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)器堆迭縮小為(wei)一(yi)個(ge)工控(kong)(kong)(kong)(kong)(kong)(kong)計(ji)算機，將(jiang)復雜而數(shu)量龐(pang)大(da)的(de)(de)(de)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)電纜(lan)變為(wei)一(yi)根串行(xing)電話線。它(ta)將(jiang)中遠程(cheng)監(jian)控(kong)(kong)(kong)(kong)(kong)(kong)變為(wei)事實、為(wei)Internet遠程(cheng)監(jian)控(kong)(kong)(kong)(kong)(kong)(kong)提(ti)供(gong)可(ke)能。但數(shu)字(zi)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)也不(bu)是(shi)(shi)(shi)(shi)那么十(shi)全十(shi)美，控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)主(zhu)機的(de)(de)(de)價格十(shi)分(fen)昂貴、模(mo)(mo)(mo)塊浪費的(de)(de)(de)情況、系(xi)統(tong)(tong)可(ke)能出現全線崩潰的(de)(de)(de)危機、控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)較為(wei)滯后(hou)等等問題(ti)仍然存(cun)在。
