style="text-indent:25px">防爆攝像機(jī)監(jiān)控系統(tǒng)的常見故障及排除：1、電源不正確引發(fā)的設(shè)備故障，電源不正確大致有如下幾種可能。a、供電線路或供電電壓不正確。b、功率不夠(或某一路供電線路的線徑不夠，降壓過大等)。c、供是系統(tǒng)的傳輸線路出現(xiàn)短路、斷路、瞬間過壓等。d.特別是因供電錯(cuò)誤或瞬間過壓導(dǎo)致設(shè)備損壞的情況時(shí)有發(fā)生，因此，在系統(tǒng)調(diào)試以前，供電以前，一定要認(rèn)真嚴(yán)格的進(jìn)行核對(duì)與檢查，絕不應(yīng)掉以輕心。2、云臺(tái)的故障。一個(gè)云臺(tái)在使用后不久就運(yùn)轉(zhuǎn)不靈或根本不能轉(zhuǎn)動(dòng)，是云臺(tái)常見故障。這種情況的出現(xiàn)除去產(chǎn)品質(zhì)量的因素外，一般是以下各種原因造成的：a、只允許將攝像機(jī)正裝的云臺(tái)，在使用時(shí)采用了吊裝的方式。在這種情況下，吊裝方式導(dǎo)致了云臺(tái)運(yùn)轉(zhuǎn)負(fù)荷加大，故使用不久就會(huì)導(dǎo)致云臺(tái)的傳動(dòng)機(jī)構(gòu)損壞，甚至燒毀電機(jī)。b、攝像機(jī)及其防護(hù)罩等總重量超過云臺(tái)的承重。特別是室外使用的云臺(tái)，往往防護(hù)罩的重量過大，常會(huì)出現(xiàn)云臺(tái)轉(zhuǎn)不動(dòng)(特別是垂直方向轉(zhuǎn)不動(dòng))的問題。c、室外云臺(tái)因環(huán)境溫度過高、過低、防水、防凍措施不良而出現(xiàn)故障甚至損壞。</p><p style="text-indent:25px">防爆攝像機(jī)的安裝：室外安裝：在室外安裝立桿或依附載體安裝監(jiān)控防爆攝像機(jī)，采用正面攝像或側(cè)面攝像拍攝出入口圖像。此種方式已經(jīng)逐漸被接受和采用，并取得較好的成像效果。這種方式的優(yōu)點(diǎn)是，白天室外自然光環(huán)境人臉面部光照充分，面部圖像真實(shí)，層次分明，能拍攝更多人體特征細(xì)節(jié)。晚上出入口處環(huán)境照明單一，在環(huán)境照明充分的情況下也可得到滿意的夜間人像。該種安裝方式，根據(jù)夜間的環(huán)境照度情況可選用低照度監(jiān)控防爆攝像機(jī)或普通照度監(jiān)控防爆攝像機(jī)。這種安裝方式的缺點(diǎn)是，安裝位置受景觀限制，布線略麻煩，某些項(xiàng)目需要涉及切割路面，需要考慮室外景觀環(huán)境。某些建筑出入口受環(huán)境限制無法選用此種方式。在建筑環(huán)境容許的情況下，建議優(yōu)先選擇室外安裝方式，同時(shí)做好夜間出入口室外的照明。遇接觸不良點(diǎn)就產(chǎn)生火花、電弧或高溫，有可能環(huán)境中的性氣體。</p><div

style="text-indent:25px">防爆攝像機(jī)監(jiān)控系統(tǒng)的常見故障及排除：由于供電系統(tǒng)的電源不“潔凈”而引起的。這里所指的電源不“潔凈”，是指在正常的電源(50周的正弦波)上疊加有干擾信號(hào)。而這種電源上的干擾信號(hào)，多來自本電網(wǎng)中使用可控硅的設(shè)備。特別是大電流、高壓電的可控硅設(shè)備，對(duì)電網(wǎng)的污染非常嚴(yán)重，這就導(dǎo)致了同一電網(wǎng)中的電源不“潔凈”。比如本電網(wǎng)中有大功率可控硅調(diào)頻調(diào)速裝置、可控硅整流裝置、可控硅交直流變換裝置等等，都會(huì)對(duì)電源產(chǎn)生污染。這種情況的解決方法比較簡單，只要對(duì)整個(gè)系統(tǒng)采用凈化電源或在線UPS供電就基本上可以得到解決。統(tǒng)附近有很強(qiáng)的干擾源。這可以通過調(diào)查和了解而加以判斷。如果屬于這種原因，解決的辦法是加強(qiáng)攝像機(jī)的屏蔽，以及對(duì)視頻電纜線的管道進(jìn)行接地處理等。節(jié)LEVEL電位器使光圈在適宜方位。咸陽工業(yè)防爆監(jiān)控?cái)z像機(jī)哪家好</p><p
