安防監控工程 檢測實用方(fang)法

      如(ru)今安(an)(an)防監控工(gong)程在(zai)城市(shi)建設過程中應用(yong)越來越廣泛，如(ru)果工(gong)程出現問題會(hui)給使用(yong)方造成損(sun)失。為了將(jiang)安(an)(an)防監控工(gong)程做(zuo)好，真正讓用(yong)戶滿意放心(xin)，安(an)(an)防工(gong)程必須經過有公安(an)(an)部(bu)授權的檢(jian)測(ce)機(ji)構檢(jian)測(ce)合格后(hou)方能投入使用(yong)。

安防監控系(xi)統工程檢測實用方法

      安(an)(an)防監控系統(tong)(tong)工(gong)(gong)程大多依據GB50348——2004《安(an)(an)全防范工(gong)(gong)程技(ji)術規范》和(he)GA/T669《城市(shi)監控報警聯網(wang)系統(tong)(tong)通用(yong)技(ji)術要求》及各個地方(fang)招標文件的(de)技(ji)術條(tiao)款設計實(shi)施的(de)。安(an)(an)防監控系統(tong)(tong)工(gong)(gong)程的(de)檢驗(yan)內(nei)容(rong)主要包(bao)括：系統(tong)(tong)性能、系統(tong)(tong)功能、電源供(gong)電、設備安(an)(an)全性、防雷接地、電磁兼容(rong)性和(he)安(an)(an)裝施工(gong)(gong)工(gong)(gong)藝等。

      在(zai)工(gong)(gong)程(cheng)(cheng)現場(chang)檢(jian)驗(yan)之前，工(gong)(gong)程(cheng)(cheng)的(de)(de)受檢(jian)方(fang)應事(shi)先提交與工(gong)(gong)程(cheng)(cheng)相關(guan)的(de)(de)各(ge)項資(zi)料：包括施工(gong)(gong)合同、技術(shu)方(fang)案(an)、使用(yong)設(she)備清單、相關(guan)產品的(de)(de)檢(jian)驗(yan)報(bao)告(gao)、隱(yin)蔽(bi)工(gong)(gong)程(cheng)(cheng)的(de)(de)驗(yan)收報(bao)告(gao)、安防(fang)工(gong)(gong)程(cheng)(cheng)施工(gong)(gong)資(zi)質，以及工(gong)(gong)程(cheng)(cheng)試運(yun)行(xing)期間(jian)的(de)(de)運(yun)行(xing)記錄(lu)等。其中(zhong)施工(gong)(gong)技術(shu)方(fang)案(an)作(zuo)為(wei)檢(jian)驗(yan)的(de)(de)重(zhong)要(yao)(yao)依據，要(yao)(yao)嚴格按(an)照國(guo)家(jia)的(de)(de)相關(guan)安防(fang)技術(shu)標準執行(xing)。檢(jian)驗(yan)人員還(huan)要(yao)(yao)聽取使用(yong)方(fang)對(dui)有關(guan)工(gong)(gong)程(cheng)(cheng)特殊要(yao)(yao)求(qiu)的(de)(de)說明，并了解施工(gong)(gong)方(fang)在(zai)施工(gong)(gong)過程(cheng)(cheng)中(zhong)遇(yu)到的(de)(de)問題。

      一、視頻(pin)監控系統（性(xing)能功能）檢測

      依據(ju)工(gong)程(cheng)技(ji)術(shu)(shu)方案的(de)設備(bei)清單，一要(yao)查(cha)看開通路數(shu)情(qing)況是(shi)否符合設計要(yao)求(qiu)(qiu)；二要(yao)查(cha)看圖像質(zhi)量(liang)(liang)。圖像質(zhi)量(liang)(liang)是(shi)判別整(zheng)個工(gong)程(cheng)優劣(lie)的(de)最直觀的(de)依據(ju)，圖像的(de)質(zhi)量(liang)(liang)主要(yao)取決于前端攝像機的(de)分(fen)辨(bian)率。按照GB50198《民用閉路監視電視系統工(gong)程(cheng)技(ji)術(shu)(shu)規(gui)范》規(gui)定，彩色電視機線數(shu)不(bu)低于270線，回(hui)放不(bu)低于220線。查(cha)看每一路圖像是(shi)否符合要(yao)求(qiu)(qiu)；三要(yao)查(cha)看每路圖像切換情(qing)況，保(bao)證圖像的(de)監視位(wei)置符合要(yao)求(qiu)(qiu)，需監視的(de)部位(wei)無盲區、無死(si)角(jiao)。

      二、安裝與施(shi)工(gong)(gong)工(gong)(gong)藝的檢測

      在整個安(an)(an)(an)防工(gong)(gong)(gong)程(cheng)當中，設備的(de)(de)(de)安(an)(an)(an)裝(zhuang)與施(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)藝的(de)(de)(de)好壞，直(zhi)接關系(xi)到系(xi)統是否安(an)(an)(an)全可靠運行的(de)(de)(de)保證。檢(jian)測(ce)過程(cheng)中的(de)(de)(de)重點為：一，設備的(de)(de)(de)安(an)(an)(an)裝(zhuang)。要(yao)(yao)清點設備安(an)(an)(an)裝(zhuang)的(de)(de)(de)數量、安(an)(an)(an)裝(zhuang)位置、監控(kong)中心機柜、使用面(mian)積是否合理(li)、是否符合設計(ji)要(yao)(yao)求。二，施(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)藝檢(jian)測(ce)重點為首先要(yao)(yao)查(cha)看(kan)布線是否捆扎整齊；其次(ci)二要(yao)(yao)查(cha)看(kan)信(xin)號(hao)線與電源線是否分開排列，防止信(xin)號(hao)之間互相影響；最(zui)后(hou)要(yao)(yao)查(cha)看(kan)所有設備的(de)(de)(de)進處線是否有永(yong)久(jiu)性標(biao)志或標(biao)示，以方便日(ri)后(hou)的(de)(de)(de)維護與保養(yang)；對于(yu)隱蔽安(an)(an)(an)裝(zhuang)的(de)(de)(de)線纜、光纜無法(fa)現場檢(jian)驗檢(jian)測(ce)的(de)(de)(de)部分，應要(yao)(yao)求收檢(jian)方提供詳(xiang)實的(de)(de)(de)隱蔽工(gong)(gong)(gong)程(cheng)驗收單或檢(jian)驗報(bao)告。

      三、電源供電系統(tong)檢測(ce)

      電(dian)(dian)(dian)(dian)(dian)(dian)源供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)系統(tong)(tong)是(shi)保(bao)證(zheng)整個系統(tong)(tong)工(gong)程(cheng)安(an)全正(zheng)(zheng)常(chang)工(gong)作的(de)重要部分，在(zai)檢(jian)(jian)驗(yan)(yan)驗(yan)(yan)收(shou)過(guo)程(cheng)中要嚴格按照設計(ji)(ji)文件或(huo)施工(gong)合(he)同逐項(xiang)進(jin)行(xing)，其(qi)(qi)重點(dian)是(shi)查(cha)看(kan)(kan)系統(tong)(tong)的(de)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)方式。對于重點(dian)工(gong)程(cheng)要求(qiu)有(you)兩路市電(dian)(dian)(dian)(dian)(dian)(dian)與(yu)UPS電(dian)(dian)(dian)(dian)(dian)(dian)源供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)：一(yi)，如為市電(dian)(dian)(dian)(dian)(dian)(dian)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)要檢(jian)(jian)測其(qi)(qi)市電(dian)(dian)(dian)(dian)(dian)(dian)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓是(shi)否正(zheng)(zheng)常(chang)穩定；二(er)，UPS電(dian)(dian)(dian)(dian)(dian)(dian)源供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)是(shi)保(bao)證(zheng)或(huo)避免系統(tong)(tong)因突然市電(dian)(dian)(dian)(dian)(dian)(dian)斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)而(er)造成數據丟失(shi)和(he)設備的(de)損(sun)壞(huai)。在(zai)檢(jian)(jian)測驗(yan)(yan)收(shou)過(guo)程(cheng)中：一(yi)要進(jin)行(xing)斷(duan)市電(dian)(dian)(dian)(dian)(dian)(dian)試驗(yan)(yan)，查(cha)看(kan)(kan)設備運行(xing)情況及UPS電(dian)(dian)(dian)(dian)(dian)(dian)源供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)情況；二(er)要在(zai)斷(duan)市電(dian)(dian)(dian)(dian)(dian)(dian)試驗(yan)(yan)后實(shi)地查(cha)看(kan)(kan)所(suo)用設備是(shi)否真(zhen)正(zheng)(zheng)實(shi)現UPS電(dian)(dian)(dian)(dian)(dian)(dian)源供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)、設備是(shi)否工(gong)作正(zheng)(zheng)常(chang)；三要檢(jian)(jian)測或(huo)計(ji)(ji)算UPS電(dian)(dian)(dian)(dian)(dian)(dian)源的(de)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)時間(jian)與(yu)容量，是(shi)否滿足符合(he)設計(ji)(ji)與(yu)使用要求(qiu)。

      四、防雷與(yu)接地措施檢測

      對(dui)于安(an)防系統工(gong)程(cheng)(cheng)來(lai)講，防雷(lei)(lei)與(yu)接地最大的(de)威(wei)脅一是(shi)(shi)直擊(ji)雷(lei)(lei)對(dui)安(an)裝在(zai)室(shi)外(wai)的(de)前端設(she)(she)(she)備(bei)的(de)危害(hai)；二是(shi)(shi)感應(ying)雷(lei)(lei)對(dui)監控中心設(she)(she)(she)備(bei)和操(cao)作人員的(de)危害(hai)。防雷(lei)(lei)與(yu)接地措施是(shi)(shi)保證(zheng)系統設(she)(she)(she)備(bei)安(an)全(quan)運行不被(bei)雷(lei)(lei)擊(ji)，減(jian)少損(sun)失的(de)必要(yao)保證(zheng)，應(ying)嚴格按照(zhao)設(she)(she)(she)計文件及GB50348——2004《安(an)全(quan)防范工(gong)程(cheng)(cheng)技術(shu)規范》標準進行檢測(ce)。在(zai)檢測(ce)中一是(shi)(shi)要(yao)查看前端設(she)(she)(she)備(bei)是(shi)(shi)否安(an)裝避雷(lei)(lei)設(she)(she)(she)備(bei)，避雷(lei)(lei)設(she)(she)(she)備(bei)的(de)選型是(shi)(shi)否符合；二是(shi)(shi)查看連接線的(de)選型與(yu)安(an)裝是(shi)(shi)否符合；三是(shi)(shi)要(yao)測(ce)量接地電阻是(shi)(shi)否符合，對(dui)重點工(gong)程(cheng)(cheng)還(huan)應(ying)依據當(dang)地氣象(xiang)部門提(ti)供的(de)檢測(ce)報告，綜合檢驗情(qing)況(kuang)，給予客觀的(de)數據和結論。

      五(wu)、設備安全性和電(dian)磁兼(jian)容(rong)性檢驗

      在安防監控工(gong)程中(zhong)，設(she)備(bei)的(de)(de)安全(quan)性測(ce)試(shi)是為了設(she)備(bei)在投入運行(xing)的(de)(de)過(guo)程中(zhong)，能夠(gou)保證操作(zuo)者人身健康、安全(quan)和設(she)備(bei)本身安全(quan)技術(shu)要(yao)求(qiu)。應按照(zhao)工(gong)程系統中(zhong)的(de)(de)設(she)備(bei)數量，按照(zhao)比例要(yao)求(qiu)抽取設(she)備(bei)，并逐一對設(she)備(bei)的(de)(de)耐壓、絕緣(yuan)、泄漏、靜放電、抗擾度等進行(xing)測(ce)試(shi)驗收。
