詳情

  新的(de)(de)時(shi)(shi)代環境給人們帶(dai)(dai)來(lai)(lai)了舒服的(de)(de)生活(huo)(huo),時(shi)(shi)代的(de)(de)變遷更新也給如今的(de)(de)社會形勢帶(dai)(dai)來(lai)(lai)各種新的(de)(de)問題。市(shi)場(chang)經濟的(de)(de)深入,城(cheng)市(shi)流動人口(kou)的(de)(de)逐步(bu)增(zeng)多(duo),隨之而來(lai)(lai)的(de)(de)搶劫、盜竊等犯(fan)罪活(huo)(huo)動日(ri)益嚴重。如果沒有及時(shi)(shi)有效的(de)(de)處理(li)措施,共建和諧社會就(jiu)無從(cong)談起(qi),現(xian)在機場(chang)、港口(kou)、企業、大多(duo)數(shu)住宅小區均已經使用了周界報警系統(tong)來(lai)(lai)進行安全(quan)防范。

  什么叫周(zhou)界(jie)(jie)防(fang)入(ru)侵(qin)或周(zhou)界(jie)(jie)報(bao)警(jing)系統呢?簡單來講就是任(ren)何一個(ge)區域外圍一圈做防(fang)護(hu),利用設(she)備(bei)對(dui)設(she)防(fang)區域的(de)非法入(ru)侵(qin)、盜(dao)竊、破(po)壞和搶(qiang)劫等(deng)進行(xing)實時有效的(de)探測和報(bao)警(jing),比(bi)如(ru)小區圍墻上的(de)周(zhou)界(jie)(jie)防(fang)范,工廠、學校圍墻上的(de)周(zhou)界(jie)(jie)防(fang)范,別墅(shu)圍墻或柵(zha)欄的(de)防(fang)入(ru)侵(qin)等(deng)等(deng)。

  為(wei)(wei)了防(fang)止非法入侵和(he)(he)各種破(po)壞活動,最(zui)早之前(qian)圍墻和(he)(he)狼狗(gou)是曾經最(zui)樸(pu)素的(de)(de)周(zhou)界防(fang)護(hu)。正(zheng)所謂(wei)“水漲船高”,犯罪分(fen)(fen)子也逐漸學會(hui)了更科技(ji)化的(de)(de)手段(duan),傳統的(de)(de)防(fang)范方式已經跟不上“技(ji)術(shu)流(liu)”犯罪分(fen)(fen)子的(de)(de)步伐,安(an)(an)裝(zhuang)先進的(de)(de)安(an)(an)全技(ji)術(shu)防(fang)范系統就成(cheng)了必(bi)然措施(shi),筆者(zhe)作為(wei)(wei)深耕安(an)(an)防(fang)領域7年的(de)(de)資深從(cong)業人(ren)員,今(jin)天試著去和(he)(he)大家一起分(fen)(fen)析(xi)現(xian)如今(jin)的(de)(de)周(zhou)界技(ji)術(shu)防(fang)入侵的(de)(de)幾(ji)大常見產(chan)品和(he)(he)優缺點。

  一、電子(zi)圍欄

說到電(dian)(dian)子(zi)(zi)圍(wei)(wei)欄(lan),相(xiang)信大家并不陌(mo)生,電(dian)(dian)子(zi)(zi)圍(wei)(wei)欄(lan)由電(dian)(dian)子(zi)(zi)圍(wei)(wei)欄(lan)主機和前端探測圍(wei)(wei)欄(lan)組成,一(yi)般(ban)分(fen)高(gao)壓脈沖(chong)式電(dian)(dian)子(zi)(zi)圍(wei)(wei)欄(lan),張力電(dian)(dian)子(zi)(zi)圍(wei)(wei)欄(lan),高(gao)壓脈沖(chong)加張力電(dian)(dian)子(zi)(zi)圍(wei)(wei)欄(lan)等等。這幾(ji)類(lei)產品各有優缺點(dian),最(zui)常(chang)用的是高(gao)壓脈沖(chong)式電(dian)(dian)子(zi)(zi)圍(wei)(wei)欄(lan)。

  高(gao)(gao)壓脈(mo)沖(chong)(chong)式電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)圍(wei)(wei)欄是(shi)(shi)(shi)一種(zhong)主動入(ru)(ru)侵(qin)防(fang)越系統(tong),對(dui)(dui)入(ru)(ru)侵(qin)企圖做(zuo)出反擊(ji)(ji),擊(ji)(ji)退(tui)入(ru)(ru)侵(qin)者,延遲入(ru)(ru)侵(qin)時(shi)間(jian)。脈(mo)沖(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)圍(wei)(wei)欄由帶電(dian)(dian)(dian)(dian)(dian)(dian)脈(mo)沖(chong)(chong)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)纜線(xian)(xian)組成(cheng)(cheng)。電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)纜線(xian)(xian)產(chan)生(sheng)的(de)(de)(de)非致命脈(mo)沖(chong)(chong)高(gao)(gao)壓能(neng)(neng)有效擊(ji)(ji)退(tui)入(ru)(ru)侵(qin)者,并(bing)把入(ru)(ru)侵(qin)信號發送到安全(quan)部(bu)門監(jian)控設備上,以(yi)保證(zheng)管理(li)人(ren)員能(neng)(neng)及時(shi)了解(jie)報(bao)(bao)警(jing)(jing)區(qu)域的(de)(de)(de)情況(kuang),快速(su)的(de)(de)(de)作出處理(li),具有強(qiang)大(da)的(de)(de)(de)阻擋作用(yong)(yong)(yong)和威(wei)懾(she)作用(yong)(yong)(yong),是(shi)(shi)(shi)一種(zhong)非常(chang)強(qiang)力(li)的(de)(de)(de)周界報(bao)(bao)警(jing)(jing)系統(tong),廣泛(fan)用(yong)(yong)(yong)于重點文物場(chang)所(suo)、軍事(shi)設施(shi)、監(jian)獄、看(kan)守所(suo)等(deng)(deng)場(chang)所(suo)。但(dan)(dan)是(shi)(shi)(shi)高(gao)(gao)壓脈(mo)沖(chong)(chong)式電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)圍(wei)(wei)欄也存(cun)在(zai)比較多(duo)的(de)(de)(de)問(wen)題(ti),如高(gao)(gao)壓電(dian)(dian)(dian)(dian)(dian)(dian)存(cun)在(zai)安全(quan)隱患(huan),雨雪天(tian)誤(wu)報(bao)(bao)(漏電(dian)(dian)(dian)(dian)(dian)(dian)),對(dui)(dui)施(shi)工(gong)人(ren)員要求高(gao)(gao)(需(xu)非常(chang)懂(dong)電(dian)(dian)(dian)(dian)(dian)(dian)路知識),需(xu)室外電(dian)(dian)(dian)(dian)(dian)(dian)源線(xian)(xian)和網線(xian)(xian)(施(shi)工(gong)復雜,維護成(cheng)(cheng)本高(gao)(gao)),電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)設備易(yi)壞(huai)(怕冷熱變化,雨雪腐蝕),怕雷擊(ji)(ji)(線(xian)(xian)路連接,易(yi)招雷,雷擊(ji)(ji)后(hou)損壞(huai)整(zheng)個(ge)系統(tong))等(deng)(deng)等(deng)(deng),二其中(zhong)高(gao)(gao)壓電(dian)(dian)(dian)(dian)(dian)(dian)存(cun)在(zai)安全(quan)隱患(huan)這個(ge)問(wen)題(ti)尤為(wei)突出,不(bu)慎觸及,有可(ke)(ke)能(neng)(neng)因(yin)強(qiang)烈的(de)(de)(de)觸電(dian)(dian)(dian)(dian)(dian)(dian)感而(er)(er)造成(cheng)(cheng)失足摔落等(deng)(deng)間(jian)接的(de)(de)(de)傷害;若小孩孕婦誤(wu)觸到圍(wei)(wei)欄,也有可(ke)(ke)能(neng)(neng)產(chan)生(sheng)更嚴(yan)重后(hou)果。為(wei)了避免這類安全(quan)隱患(huan),就有了具備以(yi)下功能(neng)(neng)特點的(de)(de)(de)張力(li)式電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)圍(wei)(wei)欄:一是(shi)(shi)(shi)采用(yong)(yong)(yong)張力(li)探(tan)測技(ji)術(shu),是(shi)(shi)(shi)一種(zhong)阻擋、報(bao)(bao)警(jing)(jing)并(bing)重的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)圍(wei)(wei)欄;二是(shi)(shi)(shi)兼具阻檔和報(bao)(bao)警(jing)(jing)的(de)(de)(de)功能(neng)(neng),具有一定(ding)的(de)(de)(de)威(wei)懾(she)作用(yong)(yong)(yong)。三(san)是(shi)(shi)(shi)外露的(de)(de)(de)機械部(bu)分不(bu)帶電(dian)(dian)(dian)(dian)(dian)(dian),不(bu)會對(dui)(dui)人(ren)體造成(cheng)(cheng)直接或間(jian)接的(de)(de)(de)傷害。用(yong)(yong)(yong)戶使用(yong)(yong)(yong)更安全(quan)可(ke)(ke)靠(kao),是(shi)(shi)(shi)一種(zhong)綠(lv)色(se)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)圍(wei)(wei)欄。因(yin)其獨特的(de)(de)(de)性能(neng)(neng),國內很多(duo)小學(xue)、幼兒園安裝了此(ci)類產(chan)品。但(dan)(dan)此(ci)類產(chan)品利(li)用(yong)(yong)(yong)拉力(li)工(gong)作,一個(ge)防(fang)區(qu)一般(ban)不(bu)會大(da)于40米,價格比脈(mo)沖(chong)(chong)式電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)圍(wei)(wei)欄貴兩倍,而(er)(er)且(qie)受雨雪天(tian)影響(xiang)更大(da)。

  隨著人們對產品性能和功能的要(yao)求(qiu)越(yue)來越(yue)高(gao)(gao),產品需要(yao)更加人性化,國內個(ge)別(bie)廠家(jia)也開發了(le)高(gao)(gao)壓脈沖式加張(zhang)力式電子圍欄。

  電子(zi)圍欄(lan)統一存(cun)在美(mei)觀(guan)度不夠,施(shi)工(gong)難度高(gao)(gao),維護成本高(gao)(gao),造價較高(gao)(gao),較強的牢籠感等缺點。不過它具有(you)斷路、短路、失電報警功(gong)能同時又秉承了(le)震(zhen)懾(she)、阻擋(dang)的功(gong)能。仍是現周(zhou)界(jie)安防項(xiang)目的比較好的選擇。

  二、紅(hong)外對射

  簡單來說,紅(hong)外(wai)對(dui)(dui)(dui)射利(li)用(yong)不(bu)可見紅(hong)外(wai)光對(dui)(dui)(dui)射原(yuan)理,裝置(zhi)光束遮(zhe)斷(duan)(duan)方式的探測器,當有人橫(heng)跨過(guo)監控防(fang)護區(qu)時(shi),遮(zhe)斷(duan)(duan)不(bu)可見的紅(hong)外(wai)線光束而引(yin)發警報(bao)。比如人在攀爬越過(guo)紅(hong)外(wai)對(dui)(dui)(dui)射的對(dui)(dui)(dui)射區(qu)域時(shi)就會(hui)被檢測到(dao),隨之轉變為報(bao)警信號報(bao)告給接收主機。相比較電子(zi)圍欄,紅(hong)外(wai)對(dui)(dui)(dui)射憑(ping)借其報(bao)警點位相對(dui)(dui)(dui)精準、安裝成本低(di)以及其相對(dui)(dui)(dui)隱(yin)蔽的防(fang)衛方式,使(shi)入侵者(zhe)在不(bu)知不(bu)覺中觸(chu)警等特(te)點,得到(dao)廣(guang)泛的應用(yong)。下面(mian)我們分(fen)析下常見的幾種(zhong)紅(hong)外(wai)對(dui)(dui)(dui)射及其優缺點。

  1、有線(xian)紅外對射

顧名思(si)義,所(suo)謂有線(xian)(xian)(xian)紅(hong)外(wai)對(dui)射(she)(she)即該(gai)類(lei)紅(hong)外(wai)對(dui)射(she)(she)需(xu)要(yao)外(wai)接(jie)線(xian)(xian)(xian)。外(wai)接(jie)線(xian)(xian)(xian)分為兩種,一(yi)種是(shi)電(dian)源(yuan)線(xian)(xian)(xian),就是(shi)通過市(shi)電(dian)給紅(hong)外(wai)對(dui)射(she)(she)供電(dian);另一(yi)種是(shi)信(xin)號(hao)線(xian)(xian)(xian),也(ye)就是(shi)紅(hong)外(wai)對(dui)射(she)(she)檢測到有物體穿(chuan)過對(dui)射(she)(she)區(qu)域后轉(zhuan)變(bian)的報(bao)警信(xin)號(hao),是(shi)通過連(lian)(lian)接(jie)線(xian)(xian)(xian)的方式報(bao)告給接(jie)收(shou)主機。這類(lei)探(tan)測器的優點(dian)顯而(er)易(yi)見:一(yi)是(shi)電(dian)力充(chong)足,無須(xu)考慮電(dian)不夠(gou)(gou)問題; 二是(shi)有線(xian)(xian)(xian)的報(bao)警信(xin)號(hao)傳輸(shu)非常穩(wen)定,不存在無線(xian)(xian)(xian)報(bao)警信(xin)號(hao)被干擾(rao)的問題; 但(dan)(dan)是(shi)它的缺(que)點(dian)也(ye)很(hen)(hen)突出:一(yi)是(shi)安裝起來比較麻煩,需(xu)要(yao)專(zhuan)業人(ren)員進行施(shi)工(gong)(gong);二是(shi)碰到停電(dian)或者(zhe)線(xian)(xian)(xian)路(lu)損壞的話,對(dui)射(she)(she)無法正(zheng)常工(gong)(gong)作(zuo),并且售后維修也(ye)是(shi)一(yi)件(jian)棘手的事情;三是(shi)行業門檻太低,國(guo)內很(hen)(hen)多的報(bao)警器生產(chan)廠家純粹依靠模(mo)仿就能生產(chan),導致紅(hong)外(wai)對(dui)射(she)(she)質量參(can)差不齊;四(si)是(shi)只采用(yong)(yong)紅(hong)外(wai)脈沖光(guang)(guang),光(guang)(guang)穿(chuan)透力不夠(gou)(gou),起霧下雨的時(shi)候誤報(bao)非常的高;五是(shi)采用(yong)(yong)連(lian)(lian)續光(guang)(guang)的工(gong)(gong)作(zuo)機制,發光(guang)(guang)管收(shou)光(guang)(guang)管都24小(xiao)時(shi)不間斷工(gong)(gong)作(zuo),衰減很(hen)(hen)快,使用(yong)(yong)壽(shou)命(ming)一(yi)般為1-2年,非常短。六(liu)是(shi)雷暴季(ji)節容易(yi)受到雷擊(ji),因全部(bu)設備(bei)有源(yuan)連(lian)(lian)接(jie),會導致整(zheng)體損壞,系(xi)統癱(tan)瘓。總(zong)的來講,有線(xian)(xian)(xian)紅(hong)外(wai)對(dui)射(she)(she)雖然目前廣泛應用(yong)(yong)于各類(lei)場(chang)所(suo),但(dan)(dan)是(shi)高誤報(bao)、高維護(hu)、短使用(yong)(yong)壽(shou)命(ming)一(yi)直困擾(rao)著(zhu)大家。

  2、太(tai)陽能無線(xian)紅(hong)外對射

太(tai)陽能無(wu)(wu)線(xian)(xian)(xian)(xian)紅(hong)(hong)(hong)外(wai)(wai)對(dui)射是在有(you)線(xian)(xian)(xian)(xian)紅(hong)(hong)(hong)外(wai)(wai)對(dui)射的(de)(de)(de)(de)(de)(de)基礎上(shang)(shang)進行了(le)(le)(le)一(yi)些(xie)重(zhong)大升級。首先它(ta)采用(yong)(yong)太(tai)陽光(guang)(guang)(guang)能中(zhong)的(de)(de)(de)(de)(de)(de)自然光(guang)(guang)(guang)轉換成電能的(de)(de)(de)(de)(de)(de)方式(shi)(shi)給紅(hong)(hong)(hong)外(wai)(wai)對(dui)射供(gong)電,無(wu)(wu)需太(tai)陽光(guang)(guang)(guang)直射,解(jie)決(jue)了(le)(le)(le)陰雨天、背陰面(mian)供(gong)電的(de)(de)(de)(de)(de)(de)問(wen)(wen)題(ti),也(ye)解(jie)決(jue)了(le)(le)(le)有(you)線(xian)(xian)(xian)(xian)紅(hong)(hong)(hong)外(wai)(wai)對(dui)射需要鋪(pu)設電源線(xian)(xian)(xian)(xian)的(de)(de)(de)(de)(de)(de)問(wen)(wen)題(ti);其次它(ta)采用(yong)(yong)的(de)(de)(de)(de)(de)(de)是跳頻的(de)(de)(de)(de)(de)(de)無(wu)(wu)線(xian)(xian)(xian)(xian)信號(hao)傳輸方式(shi)(shi),解(jie)決(jue)了(le)(le)(le)無(wu)(wu)線(xian)(xian)(xian)(xian)信號(hao)被干擾的(de)(de)(de)(de)(de)(de)問(wen)(wen)題(ti),也(ye)解(jie)決(jue)了(le)(le)(le)有(you)線(xian)(xian)(xian)(xian)紅(hong)(hong)(hong)外(wai)(wai)對(dui)射需要鋪(pu)設信號(hao)線(xian)(xian)(xian)(xian)的(de)(de)(de)(de)(de)(de)問(wen)(wen)題(ti),結合(he)上(shang)(shang)述,使紅(hong)(hong)(hong)外(wai)(wai)對(dui)射做到(dao)了(le)(le)(le)真正(zheng)意義上(shang)(shang)的(de)(de)(de)(de)(de)(de)全無(wu)(wu)線(xian)(xian)(xian)(xian)安裝,從技術(shu)(shu)層(ceng)面(mian)上(shang)(shang)來說確(que)實有(you)了(le)(le)(le)顛(dian)覆性的(de)(de)(de)(de)(de)(de)進展。不(bu)過(guo),這(zhe)類(lei)產(chan)(chan)品要做穩定,對(dui)生(sheng)產(chan)(chan)廠家(jia)的(de)(de)(de)(de)(de)(de)研發(fa)和(he)生(sheng)產(chan)(chan)要求非(fei)常(chang)高,行業門(men)檻比較高,據筆(bi)者了(le)(le)(le)解(jie)市(shi)場(chang)(chang)上(shang)(shang)僅有(you)少數幾家(jia)相對(dui)專業的(de)(de)(de)(de)(de)(de)報警(jing)廠家(jia)在生(sheng)產(chan)(chan)和(he)銷(xiao)售。它(ta)的(de)(de)(de)(de)(de)(de)優(you)點(dian)(dian)(dian): 一(yi)是全無(wu)(wu)線(xian)(xian)(xian)(xian)裝置,無(wu)(wu)需挖(wa)溝布線(xian)(xian)(xian)(xian),太(tai)陽板跟(gen)紅(hong)(hong)(hong)外(wai)(wai)對(dui)射一(yi)體式(shi)(shi),安裝時直接(jie)裝紅(hong)(hong)(hong)外(wai)(wai)對(dui)射再調試主機(ji)即可,施(shi)工(gong)周(zhou)(zhou)期短、簡單;二是不(bu)存在線(xian)(xian)(xian)(xian)路(lu)老化(hua)、鼠(shu)蟻(yi)啃咬線(xian)(xian)(xian)(xian)路(lu)導致短路(lu)產(chan)(chan)生(sheng)電火花(hua)的(de)(de)(de)(de)(de)(de)問(wen)(wen)題(ti),非(fei)常(chang)安全;三是穩定性好(hao),誤報率(lv)接(jie)警(jing)于0,使用(yong)(yong)壽(shou)命長達(da)8-10年。區別(bie)于有(you)線(xian)(xian)(xian)(xian)紅(hong)(hong)(hong)外(wai)(wai)對(dui)射的(de)(de)(de)(de)(de)(de)紅(hong)(hong)(hong)外(wai)(wai)脈(mo)沖(chong)連(lian)(lian)續光(guang)(guang)(guang),采用(yong)(yong)高壓脈(mo)沖(chong)點(dian)(dian)(dian)光(guang)(guang)(guang)源技術(shu)(shu),以高壓的(de)(de)(de)(de)(de)(de)形式(shi)(shi)打出紅(hong)(hong)(hong)外(wai)(wai)光(guang)(guang)(guang)點(dian)(dian)(dian),假如有(you)線(xian)(xian)(xian)(xian)紅(hong)(hong)(hong)外(wai)(wai)對(dui)射是火焰(yan)槍,太(tai)陽能無(wu)(wu)線(xian)(xian)(xian)(xian)紅(hong)(hong)(hong)外(wai)(wai)對(dui)射就像機(ji)槍。首先極大的(de)(de)(de)(de)(de)(de)加強(qiang)了(le)(le)(le)穿透力,不(bu)至(zhi)于起霧下(xia)雨的(de)(de)(de)(de)(de)(de)時候(hou)因(yin)紅(hong)(hong)(hong)外(wai)(wai)光(guang)(guang)(guang)穿透不(bu)過(guo)去產(chan)(chan)生(sheng)誤報,其次大幅的(de)(de)(de)(de)(de)(de)將紅(hong)(hong)(hong)外(wai)(wai)光(guang)(guang)(guang)的(de)(de)(de)(de)(de)(de)衰減(jian)速度降(jiang)下(xia)來,所(suo)謂(wei)點(dian)(dian)(dian)光(guang)(guang)(guang)源技術(shu)(shu)就是一(yi)秒鐘只(zhi)發(fa)送40個光(guang)(guang)(guang)點(dian)(dian)(dian),被阻斷連(lian)(lian)續4個光(guang)(guang)(guang)點(dian)(dian)(dian),既0.1S就產(chan)(chan)生(sheng)報警(jing)信號(hao),發(fa)光(guang)(guang)(guang)管(guan)(guan)跟(gen)收光(guang)(guang)(guang)管(guan)(guan)工(gong)作時間(jian)有(you)限,衰減(jian)的(de)(de)(de)(de)(de)(de)就慢,設備的(de)(de)(de)(de)(de)(de)使用(yong)(yong)壽(shou)命就長了(le)(le)(le);四(si)是采用(yong)(yong)無(wu)(wu)源連(lian)(lian)接(jie),產(chan)(chan)品本(ben)身功耗(hao)(hao)很低(功耗(hao)(hao)比手(shou)機(ji)還低),因(yin)此沒(mei)有(you)雷(lei)電感應,不(bu)怕雷(lei)擊。五是沒(mei)有(you)線(xian)(xian)(xian)(xian)材(cai)線(xian)(xian)(xian)(xian)管(guan)(guan)等輔材(cai)成本(ben),人工(gong)成本(ben)也(ye)非(fei)常(chang)省(sheng)(sheng),整(zheng)體的(de)(de)(de)(de)(de)(de)工(gong)程造(zao)價(jia)在所(suo)有(you)周(zhou)(zhou)界(jie)(jie)(jie)(jie)報警(jing)產(chan)(chan)品中(zhong)最(zui)省(sheng)(sheng)。正(zheng)因(yin)為(wei)這(zhe)些(xie)優(you)點(dian)(dian)(dian),太(tai)陽能紅(hong)(hong)(hong)外(wai)(wai)對(dui)射被廣(guang)泛應用(yong)(yong)在小區周(zhou)(zhou)界(jie)(jie)(jie)(jie)、工(gong)廠周(zhou)(zhou)界(jie)(jie)(jie)(jie)、別(bie)墅(shu)周(zhou)(zhou)界(jie)(jie)(jie)(jie)、醫(yi)院周(zhou)(zhou)界(jie)(jie)(jie)(jie)、部隊周(zhou)(zhou)界(jie)(jie)(jie)(jie)、養殖(zhi)場(chang)(chang)、果園、炸藥雷(lei)管(guan)(guan)庫等等場(chang)(chang)所(suo),發(fa)展非(fei)常(chang)迅速。

  雖然這(zhe)類光能(neng)跳頻的(de)(de)(de)太陽(yang)能(neng)無(wu)線(xian)(xian)(xian)紅(hong)(hong)外(wai)(wai)對射比有(you)線(xian)(xian)(xian)紅(hong)(hong)外(wai)(wai)對射有(you)了長足的(de)(de)(de)進步,但是(shi)(shi)它也有(you)缺點:一(yi)是(shi)(shi)單(dan)價相對較高(gao),因為(wei)增(zeng)加(jia)了一(yi)些額外(wai)(wai)的(de)(de)(de)元器件和(he)材料,并且市面上(shang)掌(zhang)握這(zhe)個技術(shu)的(de)(de)(de)廠(chang)家也不多,同類產品之間(jian)的(de)(de)(de)競(jing)爭不足所(suo)導(dao)致;二是(shi)(shi)震懾力不夠;三是(shi)(shi)兼(jian)容性(xing)不強,市面上(shang)的(de)(de)(de)報警系(xi)(xi)統前(qian)端探測設備與(yu)(yu)后端控制主(zhu)機之間(jian)的(de)(de)(de)連接(jie)基本上(shang)采用開(kai)關量(liang)信(xin)號接(jie)入(ru)的(de)(de)(de)形式(shi),所(suo)謂A的(de)(de)(de)前(qian)端可接(jie)入(ru)與(yu)(yu)B后端,而太陽(yang)能(neng)無(wu)線(xian)(xian)(xian)紅(hong)(hong)外(wai)(wai)對射采用跳頻的(de)(de)(de)無(wu)線(xian)(xian)(xian)信(xin)號傳輸就是(shi)(shi)為(wei)了解決不想拉信(xin)號的(de)(de)(de)問題(ti),所(suo)以無(wu)法與(yu)(yu)市面上(shang)的(de)(de)(de)普(pu)通報警系(xi)(xi)統直(zhi)接(jie)兼(jian)容,需要增(zeng)加(jia)一(yi)個無(wu)線(xian)(xian)(xian)轉接(jie)成有(you)線(xian)(xian)(xian)開(kai)關量(liang)的(de)(de)(de)裝置(zhi)。

  3、太陽能無線紅外光(guang)墻

目前市面上紅(hong)外(wai)(wai)對射(she)普遍都是(shi)二光(guang)(guang)(guang)束(shu),三(san)光(guang)(guang)(guang)束(shu)的紅(hong)外(wai)(wai)對射(she),防(fang)范(fan)的高度(du)一(yi)般在35公分(fen)以內,但是(shi)實際應用中有些場所,比如大門(men)口防(fang)護(hu),用三(san)二光(guang)(guang)(guang)束(shu)的對射(she)高度(du)明顯不(bu)夠;別(bie)墅的籬(li)笆式(shi)(shi)護(hu)欄,本(ben)身高度(du)就只有1米左右,需要安裝(zhuang)防(fang)范(fan)高度(du)比較(jiao)(jiao)高的紅(hong)外(wai)(wai)對射(she)來(lai)給(gei)護(hu)欄做(zuo)無(wu)形的增高;養殖(zhi)場、果園等沒有圍墻(qiang)的場所,包(bao)括開放式(shi)(shi)的小區(qu)(qu),如果做(zuo)防(fang)護(hu),都需要立地安裝(zhuang)紅(hong)外(wai)(wai)對射(she)做(zuo)防(fang)護(hu),但如果對射(she)高度(du)不(bu)夠會(hui)面臨裝(zhuang)高了(le)(le)底下(xia)人(ren)鉆進去(qu),裝(zhuang)低了(le)(le)人(ren)跨過去(qu)的尷尬情(qing)形。基(ji)于(yu)這些需求在太(tai)陽(yang)(yang)能(neng)(neng)無(wu)線(xian)(xian)紅(hong)外(wai)(wai)對射(she)基(ji)礎上研發出來(lai)了(le)(le)太(tai)陽(yang)(yang)能(neng)(neng)無(wu)線(xian)(xian)光(guang)(guang)(guang)墻(qiang),規格有4光(guang)(guang)(guang)束(shu)到八光(guang)(guang)(guang)束(shu),根據產品(pin)不(bu)同(tong),防(fang)范(fan)高度(du)60-110公分(fen),不(bu)僅大大增加(jia)了(le)(le)防(fang)范(fan)區(qu)(qu)域,而且為了(le)(le)彌補紅(hong)外(wai)(wai)對射(she)震(zhen)懾力(li)不(bu)夠的缺(que)點,太(tai)陽(yang)(yang)能(neng)(neng)無(wu)線(xian)(xian)光(guang)(guang)(guang)墻(qiang)還設計了(le)(le)自(zi)帶喇叭,具備現場報(bao)警(jing)功能(neng)(neng),有一(yi)定的震(zhen)懾力(li),當(dang)不(bu)法(fa)分(fen)子侵入時(shi)報(bao)警(jing)音突(tu)然響起,所謂“做(zuo)賊心(xin)虛(xu)”,嚇(xia)跑不(bu)法(fa)分(fen)子從(cong)而保障生(sheng)命財產不(bu)受損失。當(dang)然了(le)(le),此(ci)類產品(pin)造價(jia)也是(shi)比較(jiao)(jiao)高的。

  三、視頻監控分(fen)析技術

筆者一說視頻(pin)監控,其實(shi)大部分讀者朋友都已經知道是攝(she)像(xiang)(xiang)頭(tou)(tou)(tou)了(le)(le),這類(lei)產品在我們(men)周遭也非(fei)常常見,您(nin)可能看到(dao)過甚至(zhi)自己(ji)家里都安裝了(le)(le)攝(she)像(xiang)(xiang)頭(tou)(tou)(tou)。幾(ji)個(ge)攝(she)像(xiang)(xiang)頭(tou)(tou)(tou)匯總(zong)到(dao)一個(ge)存儲裝置上(shang)的(de)(de)顯示器來呈現畫面(mian),如(ru)有(you)事(shi)故(gu)發生需要查(cha)證的(de)(de)時候可以查(cha)詢到(dao)早期事(shi)情發生時的(de)(de)視頻(pin)圖像(xiang)(xiang),從而起到(dao)求證的(de)(de)作(zuo)用。

  隨著(zhu)技術(shu)的發展,移動(dong)偵(zhen)測技術(shu)在攝像頭中的應(ying)用(yong)越來(lai)越普及(ji)。其(qi)工作(zuo)原(yuan)理(li)為當移動(dong)物(wu)體經(jing)過攝像頭探測區域時會(hui)向后端(duan)管(guan)(guan)(guan)理(li)平臺甚至管(guan)(guan)(guan)理(li)人員手機上推(tui)送警情,起到提醒(xing)查(cha)看的作(zuo)用(yong)。此技術(shu)用(yong)于室(shi)內(nei)(nei)防范管(guan)(guan)(guan)理(li)筆者也認為非常實用(yong)跟穩定的,但是今天我們分析的是監(jian)控視(shi)頻在周界防入侵的應(ying)用(yong),室(shi)外環(huan)境相(xiang)比較室(shi)內(nei)(nei)環(huan)境復雜(za)(za)許多,動(dong)物(wu)、空氣(qi)團(tuan)的流動(dong)、暴雨大風天氣(qi)、樹枝晃(huang)動(dong)、閑雜(za)(za)人員等等因素(su)都會(hui)使(shi)該系統誤報率大大增加。

  為了滿足市場需求,視(shi)頻(pin)分(fen)(fen)析(xi)技(ji)術也在(zai)快速的(de)(de)發展,尤(you)其是自2017年的(de)(de)AI熱潮(chao)后,視(shi)頻(pin)監(jian)控分(fen)(fen)析(xi)技(ji)術更加的(de)(de)智能化。智能視(shi)頻(pin)分(fen)(fen)析(xi)技(ji)術首(shou)先將(jiang)主體(可以是人或(huo)(huo)物(wu))從監(jian)視(shi)畫面(mian)中解析(xi)出來,借助在(zai)數(shu)據庫中建立或(huo)(huo)自學獲(huo)得的(de)(de)人或(huo)(huo)物(wu)的(de)(de)各種姿態(tai)或(huo)(huo)狀(zhuang)態(tai)模型(xing),分(fen)(fen)析(xi)、比對(dui)(dui)視(shi)頻(pin)監(jian)控圖像(xiang)中的(de)(de)各種活動或(huo)(huo)物(wu)體的(de)(de)狀(zhuang)態(tai),并(bing)針對(dui)(dui)每路攝像(xiang)機(ji)設置各自的(de)(de)活動或(huo)(huo)狀(zhuang)態(tai)報(bao)告規則。若(ruo)在(zai)監(jian)視(shi)畫面(mian)中出現與(yu)規則相符(fu)的(de)(de)情景,系統即報(bao)警(jing)并(bing)發出聲、光(guang)提示,并(bing)且(qie)在(zai)主監(jian)視(shi)屏上(shang)彈(dan)出相應的(de)(de)監(jian)控畫面(mian)并(bing)錄(lu)下報(bao)警(jing)圖像(xiang)備(bei)查。

  智能視頻分析周界報(bao)警(jing)(jing)系統(tong)憑借其(qi)能提供(gong)的(de)(de)大量(liang)信(xin)息(xi)圖(tu)像信(xin)號的(de)(de)傳感器(qi),從中提取所(suo)需的(de)(de)信(xin)息(xi),根(gen)據應(ying)用(yong)場(chang)所(suo)的(de)(de)具(ju)體(ti)情況和用(yong)戶需求,策劃事(shi)件報(bao)告方案,制定相應(ying)的(de)(de)規則,使(shi)該周界報(bao)警(jing)(jing)系統(tong)達(da)到相對(dui)理(li)想(xiang)的(de)(de)使(shi)用(yong)效果(guo)。如今AI圖(tu)像分析技(ji)術(shu)作為一(yi)個(ge)新興(xing)技(ji)術(shu)也在發展(zhan),針對(dui)現(xian)如今周界報(bao)警(jing)(jing)系統(tong)所(suo)安(an)裝(zhuang)的(de)(de)較為復(fu)雜的(de)(de)外(wai)部環境,力求對(dui)圖(tu)像范(fan)圍內的(de)(de)對(dui)象(xiang)進行更(geng)精確的(de)(de)識別(bie),以減少(shao)更(geng)多的(de)(de)誤(wu)報(bao),提高準確率。但是實踐是檢驗真(zhen)理(li)的(de)(de)唯一(yi)標準,最終其(qi)效果(guo)如何(he),又會(hui)產生怎樣的(de)(de)問(wen)題,我們現(xian)在還(huan)不(bu)得(de)而(er)知(zhi),不(bu)過其(qi)發展(zhan)的(de)(de)前景依舊值得(de)我們拭目以待。

  智能視(shi)(shi)頻分析技術因需要(yao)架設視(shi)(shi)頻服務器(qi)用(yong)于記憶(yi)、存儲、圖像(xiang)計算(suan)與分析,前端攝(she)像(xiang)機的(de)構(gou)成中(zhong)也(ye)(ye)多了視(shi)(shi)頻芯(xin)片(pian)(包括AI芯(xin)片(pian)),因此施工和調試都需要(yao)非常(chang)專業,造價也(ye)(ye)非常(chang)的(de)高,實際應用(yong)場所局限于大型單位(wei)。

  目前一般(ban)場所(suo)(suo)或單位都不會考慮智能(neng)視(shi)頻(pin)分析周(zhou)界(jie)報(bao)(bao)警(jing)系(xi)統(tong),采(cai)用的(de)(de)是(shi)一般(ban)的(de)(de)視(shi)頻(pin)監(jian)控報(bao)(bao)警(jing)系(xi)統(tong),而(er)此系(xi)統(tong)又(you)與以紅外對射、電子圍欄、感應(ying)電纜等為代表的(de)(de)周(zhou)界(jie)防(fang)(fang)盜報(bao)(bao)警(jing)的(de)(de)設計理念(nian)有所(suo)(suo)不同(tong)。防(fang)(fang)盜報(bao)(bao)警(jing)注重(zhong)的(de)(de)是(shi)防(fang)(fang)賊于(yu)戶(hu)外,在(zai)損失造成之前就進行相應(ying)的(de)(de)預報(bao)(bao)。而(er)視(shi)頻(pin)監(jian)控的(de)(de)核(he)心作用是(shi)圖像采(cai)集(ji),往(wang)往(wang)用于(yu)事后處理,用戶(hu)可以通過該(gai)系(xi)統(tong)知道入侵(qin)者的(de)(de)外貌特征,從而(er)報(bao)(bao)警(jing)立案(an)。然(ran)而(er),現狀是(shi)破案(an)率較低,即使破獲損失也可能(neng)已無法挽回。

  四、振(zhen)動(dong)光纖

振動(dong)光纖作(zuo)為新(xin)型(xing)的(de)(de)(de)周界(jie)報警系(xi)統(tong)在(zai)國(guo)內(nei)的(de)(de)(de)發展(zhan)時(shi)間并不(bu)長。該系(xi)統(tong)以光纖作(zuo)為傳感探測(ce)單元,有(you)以下(xia)優點:一(yi)、無需市電供電,屬于無源探測(ce)器,有(you)效(xiao)避免(mian)了雷電干擾;二、長達500-1500米的(de)(de)(de)單防區距離(li),適(shi)合(he)大范圍周界(jie)防護;三(san)、施工(gong)相比較電子圍欄要(yao)(yao)簡單,不(bu)用挖電纜溝,直(zhi)接敷(fu)設即可,也不(bu)受地(di)形復雜(za)影(ying)響;非(fei)常(chang)適(shi)合(he)于機場、化工(gong)企業、石油管(guan)線、鐵(tie)路(lu)、小區及(ji)各類(lei)重點等區域的(de)(de)(de)入侵防范要(yao)(yao)求。雖(sui)然(ran)振動(dong)光纖有(you)很(hen)顯著的(de)(de)(de)優點,但是他的(de)(de)(de)缺點也很(hen)明顯:一(yi)、需要(yao)(yao)拉(la)光纖,整體造(zao)價跟施工(gong)難度還(huan)是高于紅外對射;二、每(mei)個防區的(de)(de)(de)距離(li)過大,就算知道有(you)侵入也很(hen)難定位(wei)具體侵入位(wei)置;三(san)、真正使用壽(shou)命不(bu)長,雨雪浸透腐蝕(shi)容易使光纖電阻增加,光纖變得特敏感,后期誤報率急(ji)劇上升(sheng)。

  五、感應電纜

  感應電(dian)纜(lan)包括(kuo)振動(dong)電(dian)纜(lan)和(he)泄露電(dian)纜(lan)兩(liang)種。作為一種室外周界入侵探測系統,它是通過發射(she)電(dian)磁(ci)波所形成(cheng)的區(qu)域進行設(she)防,當有(you)人在這個區(qu)域移動(dong)時將會對它造(zao)成(cheng)擾動(dong),從而產生報警信號。

靜電(dian)(dian)(dian)感應電(dian)(dian)(dian)纜(lan)(lan)具備了脈沖電(dian)(dian)(dian)子圍欄阻擋入侵者的(de)優點,同時(shi)又具備安(an)(an)裝相對簡便,布線方便靈活,對氣(qi)候、氣(qi)溫(wen)環境(jing)的(de)適應性(xing)能強(qiang)等(deng)優點,但是缺點同樣巨大(da):1、電(dian)(dian)(dian)纜(lan)(lan)易(yi)遭電(dian)(dian)(dian)擊,嚴重時(shi)導(dao)致整(zheng)個(ge)系(xi)統癱瘓。2、成本(ben)在所有周界報警(jing)產品中估計最(zui)高。3、電(dian)(dian)(dian)纜(lan)(lan)易(yi)受(shou)電(dian)(dian)(dian)磁波干擾。因其昂貴的(de)造價,主要的(de)應用場(chang)所只在于國(guo)境(jing)線的(de)安(an)(an)全、通信(xin)光(guang)纜(lan)(lan)電(dian)(dian)(dian)纜(lan)(lan)保護、機場(chang)、油(you)氣(qi)儲運、監獄、化工企業(ye)、石油(you)管線、鐵路等(deng)一些(xie)國(guo)家機關單位、重點地(di)區(qu)。

  總的來講(jiang),每(mei)一類產(chan)品都有其適合(he)的環境背景。比如(ru)監(jian)獄,帶強電壓(ya)的地方,倉庫等(deng)場(chang)(chang)所,防范等(deng)級(ji)非(fei)常高(gao),就(jiu)需要阻擋(dang)、震懾、警(jing)示(shi)人不要進去,電子圍欄就(jiu)非(fei)常合(he)適;而學校,小區(qu),別墅等(deng)考慮安全(quan)美觀的場(chang)(chang)所及養殖種(zhong)植場(chang)(chang),工廠(chang),炸(zha)藥庫等(deng)野外(wai)場(chang)(chang)所,太陽能(neng)無線紅外(wai)對射就(jiu)存在獨特的優勢。

  不(bu)管是電(dian)子圍(wei)欄(lan)、太陽能紅外對射、振動光纖還是視頻監控,都(dou)在(zai)周界報警(jing)方面有著(zhu)大(da)量的項目應用案例(li),只要根據自身的需(xu)求選擇適合的產(chan)品就好。
