需求分析
高鐵的安防系統(tǒng)需求非常復(fù)雜,由于屬于首次建設(shè),再加上最近幾年安防技術(shù)發(fā)展較快,尤其是視頻技術(shù)發(fā)展日新月異,原有的鐵路安防建設(shè)標(biāo)準(zhǔn)已不能適應(yīng)新的形式,本文限于篇幅,主要分析高鐵監(jiān)控市場(chǎng)的困局。
建設(shè)高鐵監(jiān)控系統(tǒng)一樣少不了標(biāo)準(zhǔn)和規(guī)范,鐵道部和有關(guān)部門共同制訂了《鐵路綜合視頻監(jiān)控系統(tǒng)技術(shù)規(guī)范》這個(gè)規(guī)范,從名稱上來(lái)看“綜合視頻監(jiān)控系統(tǒng)”就意味著不僅僅是視頻監(jiān)控這么簡(jiǎn)單,既然“綜合”肯定要考慮和其它系統(tǒng)的融合,比方說(shuō)報(bào)警系統(tǒng)、通信系統(tǒng)、控制系統(tǒng)等。按照規(guī)范的定義“綜合視頻監(jiān)控系統(tǒng)”是指“采用網(wǎng)絡(luò)化、數(shù)字化視頻監(jiān)控技術(shù)和IP傳輸方式構(gòu)建的視頻監(jiān)控系統(tǒng),提供鐵路各業(yè)務(wù)部門和信息系統(tǒng)所需的視頻信息,實(shí)現(xiàn)網(wǎng)絡(luò)和視頻信息資源共享。”同時(shí),規(guī)范還對(duì)鐵路綜合視頻監(jiān)控系統(tǒng)的網(wǎng)絡(luò)架構(gòu)做了明文規(guī)定:“鐵路綜合視頻監(jiān)控系統(tǒng)主要由視頻節(jié)點(diǎn)設(shè)備、視頻采集點(diǎn)前端設(shè)備、視頻網(wǎng)絡(luò)和用戶終端構(gòu)成。其中,視頻接入節(jié)點(diǎn)位于高鐵沿線的各站段或中間站,負(fù)責(zé)視頻的前端采集、編碼等;視頻區(qū)域節(jié)點(diǎn)位于路局及客專調(diào)度所,主要設(shè)備為分散分布的網(wǎng)絡(luò)錄像機(jī)(NVR)、DVR、存儲(chǔ)設(shè)備,同時(shí)也可進(jìn)行大屏集中監(jiān)控、網(wǎng)管、流媒體轉(zhuǎn)發(fā)等;視頻核心節(jié)點(diǎn)位于鐵道部,可對(duì)視頻監(jiān)控信息進(jìn)行調(diào)用和匯總。鐵路綜合視頻監(jiān)控系統(tǒng)的視頻業(yè)務(wù)通過(guò)數(shù)據(jù)網(wǎng)承載,視頻采集點(diǎn)的視頻信息可通過(guò)光纜、電纜或無(wú)線傳輸?shù)确绞浇尤氲剿鶎俚囊曨l接入節(jié)點(diǎn)。”
在鐵路領(lǐng)域,除了每條線都要求聯(lián)網(wǎng)管理外,甚至要求全國(guó)聯(lián)網(wǎng)。目前鐵路監(jiān)控中心設(shè)在鐵道部,全國(guó)共有20多個(gè)區(qū)域中心,區(qū)域中心下面是各級(jí)接入點(diǎn)。
基于以上的描述,可以看到高鐵監(jiān)控的建設(shè)依然會(huì)采用三級(jí)體系:視頻接入節(jié)點(diǎn)、視頻區(qū)域節(jié)點(diǎn)和視頻核心節(jié)點(diǎn),每個(gè)節(jié)點(diǎn)的功能和定位不一樣,如同縣、省、國(guó)家這種關(guān)系。筆者很快就想到了以前的變電站遠(yuǎn)程監(jiān)控系統(tǒng),因?yàn)楣P者曾經(jīng)有過(guò)一段時(shí)間的建設(shè)經(jīng)驗(yàn)。
在變電站的遠(yuǎn)程監(jiān)控中,變電站分為三種:110千伏、220千伏和500千伏三種變電站,其中500千伏變電站是有人值守變電站,另外兩種為無(wú)人值守變電站,變電站分布于各大城市周邊,其監(jiān)控就采用了三級(jí)結(jié)構(gòu)的方式,利用電力專用線路傳輸(大多數(shù)采用E1線路或者電力Intranet網(wǎng)),和高鐵的建設(shè)有非常大的相似性,變電站的遠(yuǎn)程監(jiān)控技術(shù)已經(jīng)相對(duì)比較成熟,絕對(duì)可以給高鐵監(jiān)控建設(shè)以借鑒,盡管高鐵的某些要求和應(yīng)用有所區(qū)別。
高速鐵路要求全線都設(shè)置視頻監(jiān)控系統(tǒng),設(shè)置點(diǎn)位比較多的是區(qū)間和站點(diǎn)、特大橋、隧道、公跨鐵、區(qū)間基站、變電所等。其中站點(diǎn)屬于有人值守,其它區(qū)域?qū)儆跓o(wú)人值守,監(jiān)控的具體對(duì)象可能包括:區(qū)間公跨鐵區(qū)段、通信、信號(hào)機(jī)房、牽引供電、電力供電機(jī)房?jī)?nèi)外、車站內(nèi)候車室、站臺(tái)、進(jìn)站大廳、站前廣場(chǎng)、進(jìn)站咽喉等場(chǎng)所的監(jiān)控。另外視頻監(jiān)控系統(tǒng)需要進(jìn)一步的和入侵報(bào)警系統(tǒng)、火災(zāi)報(bào)警系統(tǒng)、門禁系統(tǒng)、動(dòng)力監(jiān)控系統(tǒng)進(jìn)行融合,使得綜合視頻監(jiān)控系統(tǒng)變得更加復(fù)雜,而這恰恰就是廣大市場(chǎng)進(jìn)入者需面臨的市場(chǎng)。
另外,高鐵領(lǐng)域視頻監(jiān)控系統(tǒng)也涉及眾多業(yè)務(wù)部門,比如公安、車務(wù)段、機(jī)務(wù)段、調(diào)度段、旅客服系統(tǒng)、客運(yùn)段、貨運(yùn)段等都有各自獨(dú)特的視頻監(jiān)控需求,而這些復(fù)雜的需求要得到滿足的前提必須是:“統(tǒng)一領(lǐng)導(dǎo)、統(tǒng)一規(guī)劃、統(tǒng)一標(biāo)準(zhǔn)、統(tǒng)一資源、統(tǒng)一管理”,否則就會(huì)亂套。
高鐵安防應(yīng)用還有一個(gè)非常顯著的特點(diǎn):無(wú)人值守。為了減少小站的設(shè)置,高鐵領(lǐng)域很多場(chǎng)站都實(shí)行無(wú)人值守。另外,鐵路每隔數(shù)百米會(huì)有電力機(jī)房和通信機(jī)房,這些機(jī)房基本上都需要無(wú)人職守,并用到視頻監(jiān)控和報(bào)警系統(tǒng),以檢測(cè)是否有人入侵,現(xiàn)場(chǎng)的情況有無(wú)變化等。因此,高鐵無(wú)人值守機(jī)房對(duì)視頻監(jiān)控的需求量非常大。這就要求同一線路各專業(yè)的系統(tǒng)都集中起來(lái)管理。那么建設(shè)一套大而全、互相兼容匹配的系統(tǒng)就是高鐵視頻監(jiān)控建設(shè)的終極目標(biāo)。
高鐵是典型的垂直市場(chǎng),誰(shuí)能了解市場(chǎng)需求,提出有針對(duì)性的解決方案,誰(shuí)才是最終的贏家。但高鐵視頻監(jiān)控市場(chǎng)將面臨著諸多困局:市場(chǎng)準(zhǔn)入、設(shè)備互聯(lián)互通、兼容、統(tǒng)一的協(xié)議和規(guī)范、滿足需要的各種功能等等,這些考驗(yàn)在等待著形形色色的市場(chǎng)進(jìn)入者。
市場(chǎng)準(zhǔn)入門檻高
盡管高鐵安防蛋糕誘人,但參與過(guò)的設(shè)備供應(yīng)商和集成商無(wú)不感嘆:高鐵領(lǐng)域門檻高!高鐵項(xiàng)目由鐵道部統(tǒng)一規(guī)劃及建設(shè),對(duì)參與企業(yè)的要求非常高,具有鐵道部認(rèn)證的“四電”(通信、信號(hào)、電力、電氣化)系統(tǒng)集成商才有資格承擔(dān)高鐵“站后工程”—“四電”集成系統(tǒng)及信息系統(tǒng)的承建工作。真正擁有“四電”集成資質(zhì)的企業(yè)目前全國(guó)只有3~4家,像國(guó)鐵華晨、易程科技、中鐵電氣化局等都是代表企業(yè)。除此之外,也有一些其它企業(yè)具有較強(qiáng)的實(shí)力。國(guó)內(nèi)的安防企業(yè)大多數(shù)都處于產(chǎn)品供應(yīng)商或系統(tǒng)供應(yīng)商級(jí)別,很少企業(yè)具有垂直市場(chǎng)的“解決方案”能力,雖然平安城市、地鐵、變電站的建設(shè)培養(yǎng)了不少的解決方案供應(yīng)商,但真正能夠提供高鐵解決方案的,是少之又少。
僅僅產(chǎn)品的選型也是千里挑一,無(wú)論是前端的攝像機(jī)、傳輸端的編解碼器、后端的控制系統(tǒng)都選用了比較高端的品牌,尤其是在視頻分析方面,更是高端產(chǎn)品頻頻一統(tǒng)天下,欣喜的是中國(guó)的安防企業(yè)已經(jīng)慢慢成熟,在硬盤錄像機(jī)、模擬監(jiān)控?cái)z像機(jī)、光端機(jī)、護(hù)照、支架、云臺(tái)方面的競(jìng)爭(zhēng)力還是有的,并且在相關(guān)項(xiàng)目上已有良好的介入。
設(shè)備困局
不管是什么視頻監(jiān)控系統(tǒng),組成的設(shè)備不外乎攝像機(jī)、鏡頭、護(hù)照、編解碼器、光端機(jī)、矩陣控制設(shè)備、聯(lián)動(dòng)設(shè)備、探測(cè)器、錄像設(shè)備、遠(yuǎn)程傳輸設(shè)備、后端接入設(shè)備、軟件平臺(tái)和顯示設(shè)備等等,看似簡(jiǎn)單,實(shí)則復(fù)雜。在設(shè)備的選型上,《鐵路綜合視頻監(jiān)控系統(tǒng)技術(shù)規(guī)范》對(duì)前端攝像機(jī)、云臺(tái)、視頻編碼解設(shè)備、存儲(chǔ)設(shè)備等都有明確的技術(shù)規(guī)范。
以攝像機(jī)為例,分為模擬攝像機(jī)和網(wǎng)絡(luò)攝像機(jī)兩類,外形上可以分為半球、固定、高速球,功能上可以分為夜視、熱成像、低照度、常規(guī)照度等等,都要面臨日曬雨淋、臺(tái)風(fēng)、雷擊、暴曬、高溫、低溫這些環(huán)境因素,而高鐵監(jiān)控卻要求攝像機(jī)能夠全天候工作,不論白天、黑夜,不論地區(qū)和環(huán)境,可以講很少有企業(yè)同時(shí)能夠提供高鐵所需的所有攝像機(jī)產(chǎn)品,更沒(méi)有一家公司能供應(yīng)所需的所有軟硬件產(chǎn)品,所以這就是筆者所謂的設(shè)備困局。
所以,高鐵的設(shè)備供應(yīng)商肯定不是一家,這將對(duì)后續(xù)的維護(hù)和保養(yǎng)帶來(lái)一定的難度,而建立入圍推薦品牌將是不可避免的措施。
兼容困局
傳統(tǒng)的模擬監(jiān)控系統(tǒng)由于采用了類似有線電視的技術(shù)原理,通用性和兼容性都非常好,但綜合考慮到安防IT化的趨勢(shì),還有大量網(wǎng)絡(luò)化監(jiān)控系統(tǒng)供應(yīng)商的鼓吹、加之高鐵網(wǎng)絡(luò)傳輸?shù)男枰瑒?shì)必高鐵視頻監(jiān)控系統(tǒng)的建設(shè)將采用大量的IP產(chǎn)品,比如說(shuō)網(wǎng)絡(luò)攝像機(jī)、網(wǎng)絡(luò)編解碼器、網(wǎng)絡(luò)硬盤錄像機(jī)以及軟件平臺(tái)、視頻分析軟件等,而IP監(jiān)控系統(tǒng)最大的缺點(diǎn)就是兼容性,很少有一個(gè)后臺(tái)程序、平臺(tái)可以兼容前端五花八門的IP設(shè)備,如果采用一家公司的產(chǎn)品容易形成壟斷,不利于監(jiān)控系統(tǒng)的長(zhǎng)期穩(wěn)定的發(fā)展及維護(hù),也面臨很大的風(fēng)險(xiǎn),也可能受制于人,所以最少采用三家的IP產(chǎn)品是必須的,那么對(duì)于后端平臺(tái)供應(yīng)商的選擇尤為重要。
歷史經(jīng)驗(yàn)表明,誰(shuí)建設(shè)了視頻核心節(jié)點(diǎn)誰(shuí)將占有最高點(diǎn)、占有最多的市場(chǎng)份額,所以視頻核心節(jié)點(diǎn)的建設(shè)應(yīng)該由鐵道部統(tǒng)一規(guī)劃建設(shè),所有權(quán)和開發(fā)權(quán)應(yīng)歸屬國(guó)家,而不是屬于某個(gè)企業(yè),就顯得尤為重要。
視頻區(qū)域節(jié)點(diǎn)的平臺(tái)可以不統(tǒng)一,但必須保證能夠互聯(lián)互通,才能夠保證三級(jí)架構(gòu)的實(shí)現(xiàn),這點(diǎn)尤為重要,也正是廣大設(shè)計(jì)專家、建設(shè)者最頭痛的問(wèn)題,到底如何解決,這是一個(gè)大問(wèn)題。如果建設(shè)的不好將造成諸侯割據(jù)格局,就達(dá)不到最終的效果。
協(xié)議困局
視頻監(jiān)控系統(tǒng)中有兩個(gè)比較重要的協(xié)議,或者說(shuō)是標(biāo)準(zhǔn),那就是圖像的編解碼標(biāo)準(zhǔn)(比如H.264和MPEG4、MJPEG)和傳輸控制協(xié)議。
通常情況下,大部分產(chǎn)品都遵循了H.264和MPEG4的圖像壓縮標(biāo)準(zhǔn),即使全部采用了H.264的標(biāo)準(zhǔn)也很難保證互聯(lián)互通,用一套軟件平臺(tái)兼容所有的攝像機(jī),畢竟視頻信號(hào)在壓縮的過(guò)程中每個(gè)公司打包的原理和方式不同,加上有些攝像機(jī)有一些獨(dú)特的設(shè)置和控制參數(shù),造成了網(wǎng)絡(luò)攝像機(jī)之間的互不兼容,這是標(biāo)準(zhǔn)的困局。
云臺(tái)型攝像機(jī)主要靠控制協(xié)議完成對(duì)攝像機(jī)的控制,在模擬監(jiān)控系統(tǒng)中控制協(xié)議就沒(méi)有達(dá)成統(tǒng)一的標(biāo)準(zhǔn),到了網(wǎng)絡(luò)監(jiān)控系統(tǒng)中,這種云臺(tái)的控制協(xié)議更是每個(gè)廠家都有自己的一套獨(dú)特的方法,給云臺(tái)攝像機(jī)的控制兼容性帶來(lái)了無(wú)盡的麻煩,這是市場(chǎng)大環(huán)境使然,也是一種困局。
功能困局
高鐵視頻監(jiān)控的特點(diǎn)決定了需求上有幾個(gè)明顯的功能要求:
◆全天候監(jiān)控:如果攝像機(jī)安裝在戶外,如果一天中有12個(gè)小時(shí)看不到圖像,那么這個(gè)監(jiān)控系統(tǒng)就存在50%的監(jiān)控真空時(shí)段,尤其是對(duì)北方地區(qū)夜間更長(zhǎng)的地區(qū)來(lái)說(shuō)簡(jiǎn)直就是噩夢(mèng),所以大量的熱成像攝像機(jī)、紅外攝像機(jī)、低照度攝像機(jī)的需求是比較明顯的,但熱成像攝像機(jī)的價(jià)格居高不下。另外一個(gè)功能要求就是攝像機(jī)要適應(yīng)非常復(fù)雜的工作環(huán)境:高溫、超低溫(可能零下三十度)、雷電(經(jīng)常發(fā)生)、臺(tái)風(fēng),這些環(huán)境因素對(duì)攝像機(jī)的要求是非常高的,對(duì)那些非常惡劣的環(huán)境要求,目前還沒(méi)有非常好的解決方案。
◆無(wú)人值守:由于鐵路沿線距離非常遠(yuǎn),如果一個(gè)攝像頭故障維修成本非常高,所以對(duì)攝像機(jī)的質(zhì)量和穩(wěn)定性要求特別高。
◆視頻分析:視頻分析目前被廣泛應(yīng)用于高鐵視頻監(jiān)控當(dāng)中去,可以實(shí)現(xiàn)虛擬周界、虛擬劃線、遺留物探測(cè)、非法入侵等功能,大大減輕了人力工作,尤其是對(duì)這么大的高鐵監(jiān)控系統(tǒng)來(lái)講,效率提高了不少,但視頻分析應(yīng)用與鐵路環(huán)境,還是有一些誤報(bào)的情況存在,如發(fā)生狂風(fēng)暴雨等極端惡劣天氣、分析功能會(huì)大受影響。
◆視頻監(jiān)控系統(tǒng)通常要和入侵報(bào)警系統(tǒng)進(jìn)行集成,當(dāng)發(fā)生警情的時(shí)候,可以自動(dòng)的調(diào)用視頻信號(hào)、打開背景燈光、警笛等,這就要求視頻監(jiān)控設(shè)備具有一定的報(bào)警接入能力。
◆視頻監(jiān)控系統(tǒng)需要和其它系統(tǒng)進(jìn)行集成和聯(lián)動(dòng):比方說(shuō)和門禁系統(tǒng)、信號(hào)傳輸系統(tǒng)、環(huán)境監(jiān)控系統(tǒng)進(jìn)行集成和聯(lián)動(dòng),尤其在鐵路系統(tǒng)建設(shè)了應(yīng)急指揮系統(tǒng),那么視頻信號(hào)就格外顯得重要,那這種集成將會(huì)更加的深入、聯(lián)動(dòng)關(guān)系將會(huì)更加的復(fù)雜,這些都是高鐵視頻監(jiān)控的功能困境。
集成商困局
設(shè)備供應(yīng)商趨之若騖,系統(tǒng)集成商也不例外。按照招投標(biāo)法的規(guī)定,超過(guò)一定金額的政府項(xiàng)目是要舉行招標(biāo)活動(dòng)的,合格的供應(yīng)商最少3家,大型項(xiàng)目要求的投標(biāo)者更多,絕對(duì)不允許一、兩家企業(yè)壟斷市場(chǎng),但對(duì)于高鐵視頻監(jiān)控系統(tǒng)來(lái)講,集成商越少,兼容性、互聯(lián)互通性才會(huì)越好,才會(huì)有集中優(yōu)勢(shì),不過(guò)八仙過(guò)海、各顯神通,每個(gè)集成商都想吃這塊大蛋糕,估計(jì)最終參與高鐵安防監(jiān)控的集成商絕對(duì)不是個(gè)位數(shù),這也算是一種困局吧。
筆者說(shuō)這么多的困局,并不是想給高鐵安防系統(tǒng)的建設(shè)潑冷水,只是提一些思路和建議,供大家參考。最終希望高鐵能夠建立成一個(gè)大一統(tǒng)的平臺(tái)、也希望高鐵系統(tǒng)能夠培養(yǎng)幾個(gè)大型的安防平臺(tái)集成商和運(yùn)營(yíng)商,讓中國(guó)的解決方案提供商看到未來(lái)的希望,而不只是掌握在少數(shù)外資巨頭手里。
