方案描述
一、建設內容描述
為了某港口碼頭的安全及管理,建(jian)設(she)一套高(gao)清監控(kong)系(xi)統(tong),以滿足科學高(gao)效的管理。
二、方案說明
第一裝卸區(qu):該區(qu)域(yu)(yu)內(nei)有多(duo)(duo)個球(qiu)機(ji)和多(duo)(duo)個槍機(ji),由于現場環境所限,該區(qu)域(yu)(yu)內(nei)有部分地方(fang)不方(fang)便拉線 或者(zhe)拉線困難,采(cai)用(yong)無線網橋(qiao)將攝像(xiang)頭的信(xin)號傳輸到(dao)(dao)附近的匯聚(ju)點,匯聚(ju)點通過光纖傳輸到(dao)(dao)辦公樓機(ji)房(如下圖所示,綠色線采(cai)用(yong)無線網橋(qiao)傳輸路(lu)線)。
該碼頭(tou)(tou)有(you)兩個裝(zhuang)卸(xie)區,每個裝(zhuang)卸(xie)區都有(you)附(fu)近(jin)的(de)攝像頭(tou)(tou)信號(hao)傳輸到各自的(de)辦公樓監控中心|
方案:如下圖所(suo)示(shi):匯(hui)聚二處(chu)周圍(wei)有(you)3個(ge)點(dian)位(wei)(wei)(每個(ge)點(dian)前(qian)端(duan)有(you)多(duo)個(ge)攝(she)(she)像頭(tou)(tou)先通過有(you)線(xian)集中到交換機,再用網(wang)線(xian)和無線(xian)網(wang)橋發(fa)射端(duan)直連)需(xu)要通過無線(xian)網(wang)橋將(jiang)攝(she)(she)像頭(tou)(tou)信號傳(chuan)輸到匯(hui)聚四處(chu),每個(ge)點(dian)位(wei)(wei)配一個(ge)發(fa)射端(duan)無線(xian)網(wang)橋,采用3發(fa)一收(shou)的組網(wang)方式,將(jiang)前(qian)端(duan)3個(ge)點(dian)位(wei)(wei)處(chu)的信號用一個(ge)接收(shou)端(duan)無線(xian)網(wang)橋在匯(hui)聚二處(chu)全(quan)部接收(shou),然后一起通過光纖(xian)傳(chuan)輸到辦(ban)公室(shi)監控室(shi)。
如下(xia)圖所(suo)示:辦(ban)公樓周圍有7個(ge)點(dian)位(wei)(每個(ge)點(dian)前端(duan)有多個(ge)攝像頭先通(tong)過有線(xian)(xian)集(ji)中到交換機(ji),再(zai)用(yong)網(wang)線(xian)(xian)和無(wu)線(xian)(xian)網(wang)橋(qiao)發射端(duan)直連)需要(yao)通(tong)過無(wu)線(xian)(xian)網(wang)橋(qiao)將攝像頭信號傳輸辦(ban)公樓樓頂(ding)。
根(gen)據點(dian)(dian)位(wei)分(fen)布,每(mei)個點(dian)(dian)位(wei)配一(yi)(yi)個無線(xian)網(wang)橋發(fa)射端,根(gen)據攝像頭(tou)的數量和點(dian)(dian)位(wei)分(fen)布角度采用(yong)多(duo)發(fa)一(yi)(yi)收的的組網(wang)方(fang)式,分(fen)布3組,一(yi)(yi)組3發(fa)一(yi)(yi)收,另外兩組2發(fa)一(yi)(yi)收,3個接收端無線(xian)網(wang)橋通過網(wang)線(xian)集中到辦公樓交換機。
如下(xia)圖(tu)所示:匯(hui)聚(ju)五處有4個點位(wei)(每個點前端(duan)有多個攝像頭先通過(guo)有線(xian)(xian)集(ji)中到交換(huan)機,再連(lian)接無線(xian)(xian)網(wang)(wang)橋發射(she)端(duan))需要通過(guo)無線(xian)(xian)網(wang)(wang)橋將攝像頭的信號傳輸到匯(hui)聚(ju)五處,共(gong)分為2組,每一組2發一收。
每個點(dian)位(wei)處(chu)裝一(yi)個發射端無線網(wang)橋,在(zai)匯(hui)聚(ju)五處(chu)裝兩個接收(shou)端,分別(bie)接收(shou)前面(mian)4個發射端發射過來的視頻監(jian)控(kong)信號,接收(shou)端匯(hui)集到交換機再通過有(you)線傳(chuan)輸(shu)到辦公(gong)樓監(jian)控(kong)室。
【注】1、無(wu)線網橋必須在無(wu)遮擋的情況下才能有(you)效的傳輸,如果(guo)有(you)遮擋,只(zhi)能選擇避開遮擋或者是選一(yi)個至高點做中(zhong)繼站(拓(tuo)補圖中(zhong)黑(hei)色線為網線,紅(hong)色帶箭頭虛(xu)線為無(wu)線鏈結)。
2、每個發射(she)端不只一個攝像(xiang)頭(tou)時,多個攝像(xiang)頭(tou)先(xian)集(ji)中(zhong)到交換機,再與發射(she)端無線(xian)網橋直連。
第二裝卸(xie)區:如下(xia)圖所示,此處(chu)11個球機需要通過無線網橋傳輸到(dao)辦公(gong)樓(lou)監(jian)控(kong)中(zhong)心(xin)。其中(zhong)2#中(zhong)控(kong)樓(lou)、1#中(zhong)控(kong)樓(lou)作(zuo)為兩個主匯(hui)聚點,然后在通過光纖傳輸到(dao)辦公(gong)樓(lou)監(jian)控(kong)室。
1#中(zhong)(zhong)(zhong)控(kong)樓(lou)如(ru)下圖所示,3個球(qiu)機通(tong)過無線網(wang)橋(qiao)(qiao)匯(hui)集到1#中(zhong)(zhong)(zhong)控(kong)樓(lou),每個球(qiu)機旁裝一(yi)個無線網(wang)橋(qiao)(qiao)發射(she)端(duan),根據點位分(fen)布角(jiao)度,分(fen)為兩組(zu),一(yi)組(zu)一(yi)發一(yi)收,一(yi)組(zu)兩發一(yi)收,1#中(zhong)(zhong)(zhong)控(kong)樓(lou)兩個接收端(duan)通(tong)過有(you)線集中(zhong)(zhong)(zhong)到交換機。
2#中(zhong)(zhong)(zhong)(zhong)控(kong)樓如下圖(tu)所示,6個球機(ji)(ji)通過無(wu)線網橋匯集到2#中(zhong)(zhong)(zhong)(zhong)控(kong)樓,每個球機(ji)(ji)旁裝一個無(wu)線網橋發射端,根據點位分布角(jiao)度(du),分為兩組,每組3發一收,2#中(zhong)(zhong)(zhong)(zhong)控(kong)樓2個接(jie)收端通過有線集中(zhong)(zhong)(zhong)(zhong)到交換(huan)機(ji)(ji)。
辦(ban)公(gong)樓監控(kong)中心周圍(wei)有兩個球機需要(yao)通過無線(xian)網(wang)橋傳輸(shu),采用(yong)2發一(yi)(yi)收(shou)的(de)組網(wang)方式,每個球機旁(pang)裝(zhuang)一(yi)(yi)個發射端(duan),在辦(ban)公(gong)樓處裝(zhuang)一(yi)(yi)個接收(shou)端(duan)。
