【監控系統】監控系統的組成 安防監控系統由哪(na)幾部分組成

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(zai)人們日常生(sheng)活中接觸的(de)最多(duo)，就(jiu)目前發展開看，監控(kong)系統的(de)普(pu)及也越來越廣。幾乎(hu)所(suo)有高新(xin)科技都可(ke)促進其發展，尤(you)其是信息時代的(de)來臨，更為(wei)該專業發展提供契(qi)機。我們根據系統各部分(fen)功能的(de)不同，將整(zheng)個(ge)安防(fang)監控(kong)系統劃分(fen)為(wei)七層(ceng)——表現層(ceng)、控(kong)制層(ceng)、處(chu)理(li)層(ceng)、傳輸層(ceng)、執行層(ceng)、支(zhi)撐層(ceng)、采(cai)集(ji)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、監視器、高音報警喇叭、報警自動駁接(jie)電話等等都屬(shu)于這一層。

監控系統的組成——處理層

處理層(ceng)(ceng)(ceng)或許該稱為(wei)音(yin)視(shi)(shi)頻(pin)處理層(ceng)(ceng)(ceng)，它將有傳輸層(ceng)(ceng)(ceng)送過(guo)來(lai)的(de)音(yin)視(shi)(shi)頻(pin)信號加以(yi)分(fen)(fen)配、放(fang)大、分(fen)(fen)割(ge)等等處理，有機的(de)將表現(xian)層(ceng)(ceng)(ceng)與控制層(ceng)(ceng)(ceng)加以(yi)連(lian)接。音(yin)視(shi)(shi)頻(pin)分(fen)(fen)配器(qi)、音(yin)視(shi)(shi)頻(pin)放(fang)大器(qi)、視(shi)(shi)頻(pin)分(fen)(fen)割(ge)器(qi)、音(yin)視(shi)(shi)頻(pin)切換器(qi)等等設備都屬于這一層(ceng)(ceng)(ceng)。

監控系統的組成——控制層

控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)層是整個安防監控(kong)(kong)(kong)(kong)(kong)系(xi)(xi)統的(de)(de)(de)核心，它是系(xi)(xi)統科(ke)技水(shui)平的(de)(de)(de)最(zui)明(ming)確體現。通常我們的(de)(de)(de)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)方(fang)(fang)式(shi)有兩種——模(mo)擬(ni)(ni)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)和數(shu)(shu)字(zi)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)。模(mo)擬(ni)(ni)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)是早期的(de)(de)(de)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)方(fang)(fang)式(shi)，其(qi)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)臺通常由控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)器或者模(mo)擬(ni)(ni)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)矩陣構(gou)成(cheng)(cheng)，適(shi)用(yong)于小(xiao)(xiao)型局部安防監控(kong)(kong)(kong)(kong)(kong)系(xi)(xi)統，這(zhe)(zhe)種控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)方(fang)(fang)式(shi)成(cheng)(cheng)本較低，故障(zhang)率(lv)較小(xiao)(xiao)。但對于中大型安防監控(kong)(kong)(kong)(kong)(kong)系(xi)(xi)統而言，這(zhe)(zhe)種方(fang)(fang)式(shi)就(jiu)顯得操(cao)作(zuo)復雜且無任何(he)價格優(you)勢了，這(zhe)(zhe)時(shi)我們更為(wei)(wei)明(ming)智的(de)(de)(de)選擇(ze)應該是數(shu)(shu)字(zi)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)。數(shu)(shu)字(zi)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)是將(jiang)工控(kong)(kong)(kong)(kong)(kong)計(ji)算(suan)機作(zuo)為(wei)(wei)監控(kong)(kong)(kong)(kong)(kong)系(xi)(xi)統的(de)(de)(de)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)核心，它將(jiang)復雜的(de)(de)(de)模(mo)擬(ni)(ni)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)操(cao)作(zuo)變為(wei)(wei)簡單的(de)(de)(de)鼠(shu)標點擊操(cao)作(zuo)，將(jiang)巨(ju)大的(de)(de)(de)模(mo)擬(ni)(ni)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)器堆迭縮(suo)小(xiao)(xiao)為(wei)(wei)一個工控(kong)(kong)(kong)(kong)(kong)計(ji)算(suan)機，將(jiang)復雜而數(shu)(shu)量龐(pang)大的(de)(de)(de)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)電纜變為(wei)(wei)一根串行(xing)電話線。它將(jiang)中遠程監控(kong)(kong)(kong)(kong)(kong)變為(wei)(wei)事實、為(wei)(wei)Internet遠程監控(kong)(kong)(kong)(kong)(kong)提供可(ke)(ke)能(neng)。但數(shu)(shu)字(zi)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)也不(bu)是那(nei)么十(shi)全十(shi)美，控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)主(zhu)機的(de)(de)(de)價格十(shi)分昂(ang)貴、模(mo)塊浪費的(de)(de)(de)情況、系(xi)(xi)統可(ke)(ke)能(neng)出現全線崩潰(kui)的(de)(de)(de)危機、控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)較為(wei)(wei)滯(zhi)后(hou)等等問題仍然(ran)存在。
