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》這個規(guī)范，從名稱上來看“綜合視頻監(jiān)控系統(tǒng)”就意味著不僅僅是視頻監(jiān)控這么簡單，既然“綜合”肯定要考慮和其它系統(tǒng)的融合，比方說報警系統(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，規(guī)范還對鐵路綜合視頻監(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、存儲設(shè)備，同時也可進(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)通過數(shù)據(jù)網(wǎng)承載，視頻采集點(diǎn)的視頻信息可通過光纜、電纜或無線傳輸?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，甚至要求全國聯(lián)網(wǎng)。目前鐵路監(jiān)控中心設(shè)在鐵道部，全國共有20多個區(qū)域中心，區(qū)域中心下面是各級接入點(diǎn)。
基于以上的描述，可以看到高鐵監(jiān)控的建設(shè)依然會采用三級體系：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)，每個節(jié)點(diǎn)的功能和定位不一樣，如同縣、省、國家這種關(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)有過一段時間的建設(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)相對比較成熟，絕對可以給高鐵監(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人值守，監(jiān)控的具體對象可能包括：區(qū)間公跨鐵區(qū)段、通信、信號機(jī)房、牽引供電、電力供電機(jī)房內(nèi)外、車站內(nèi)候車室、站臺、進(jìn)站大廳、站前廣場、進(jìn)站咽喉等場所的監(jiān)控。另外視頻監(jiān)控系統(tǒng)需要進(jìn)一步的和入侵報警系統(tǒng)、火災(zāi)報警系統(tǒng)、門禁系統(tǒng)、動力監(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進(jìn)入者需面臨的市場。
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”，否則就會亂套。
高鐵安防應(yīng)用還有一個非常顯著的特點(diǎn)：無人值守。為了減少小站的設(shè)置，高鐵領(lǐng)域很多場站都實(shí)行無人值守。另外，鐵路每隔數(shù)百米會有電力機(jī)房和通信機(jī)房，這些機(jī)房基本上都需要無人職守，并用到視頻監(jiān)控和報警系統(tǒng)，以檢測是否有人入侵，現(xiàn)場的情況有無變化等。因此，高鐵無人值守機(jī)房對視頻監(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，誰能了解市場需求，提出有針對性的解決方案，誰才是最終的贏家。但高鐵視頻監(jiān)控市場將面臨著諸多困局：市場準(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進(jìn)入者。
市場準(zhǔn)入門檻高
盡管高鐵安防蛋糕誘人，但參與過的設(shè)備供應(yīng)商和集成商無不感嘆：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、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)目前全國只有3～4家，像國鐵華晨、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)商級別，很少企業(yè)具有垂直市場的“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)控攝像機(jī)、光端機(jī)、護(hù)照、支架、云臺方面的競爭力還是有的，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)動設(shè)備、探測器、錄像設(shè)備、遠(yuǎn)程傳輸設(shè)備、后端接入設(shè)備、軟件平臺和顯示設(shè)備等等，看似簡單，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》對前端攝像機(jī)、云臺、視頻編碼解設(shè)備、存儲設(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)同時能夠提供高鐵所需的所有攝像機(jī)產(chǎn)品，更沒有一家公司能供應(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，這將對后續(xù)的維護(hù)和保養(yǎng)帶來一定的難度，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，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)男枰瑒荼馗哞F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、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，很少有一個后臺程序、平臺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)的長期穩(wěn)定的發(fā)展及維護(hù)，也面臨很大的風(fēng)險，也可能受制于人，所以最少采用三家的IP產(chǎn)品是必須的，那么對于后端平臺供應(yīng)商的選擇尤為重要。
歷史經(jīng)驗(yàn)表明，誰建設(shè)了視頻核心節(jié)點(diǎn)誰將占有最高點(diǎn)、占有最多的市場份額，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)歸屬國家，而不是屬于某個企業(yè)，就顯得尤為重要。
視頻區(qū)域節(jié)點(diǎn)的平臺可以不統(tǒng)一，但必須保證能夠互聯(lián)互通，才能夠保證三級架構(gòu)的實(shí)現(xiàn)，這點(diǎn)尤為重要，也正是廣大設(shè)計專家、建設(shè)者最頭痛的問題，到底如何解決，這是一個大問題。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)中有兩個比較重要的協(xié)議，或者說是標(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，用一套軟件平臺兼容所有的攝像機(jī)，畢竟視頻信號在壓縮的過程中每個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。
云臺型攝像機(jī)主要靠控制協(xié)議完成對攝像機(jī)的控制，在模擬監(jiān)控系統(tǒng)中控制協(xié)議就沒有達(dá)成統(tǒng)一的標(biāo)準(zhǔn)，到了網(wǎng)絡(luò)監(jiān)控系統(tǒng)中，這種云臺的控制協(xié)議更是每個廠家都有自己的一套獨(dú)特的方法，給云臺攝像機(jī)的控制兼容性帶來了無盡的麻煩，這是市場大環(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個小時看不到圖像，那么這個監(jiān)控系統(tǒng)就存在50%的監(jiān)控真空時段，尤其是對北方地區(qū)夜間更長的地區(qū)來說簡直就是噩夢，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)的價格居高不下。另外一個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)、臺風(fēng)，這些環(huán)境因素對攝像機(jī)的要求是非常高的，對那些非常惡劣的環(huán)境要求，目前還沒有非常好的解決方案。
◆無人值守：由于鐵路沿線距離非常遠(yuǎn)，如果一個攝像頭故障維修成本非常高，所以對攝像機(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、非法入侵等功能，大大減輕了人力工作，尤其是對這么大的高鐵監(jiān)控系統(tǒng)來講，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、分析功能會大受影響。
◆視頻監(jiān)控系統(tǒng)通常要和入侵報警系統(tǒng)進(jìn)行集成，當(dāng)發(fā)生警情的時候，可以自動的調(diào)用視頻信號、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：比方說和門禁系統(tǒng)、信號傳輸系統(tǒng)、環(huán)境監(jiān)控系統(tǒng)進(jìn)行集成和聯(lián)動，尤其在鐵路系統(tǒng)建設(shè)了應(yīng)急指揮系統(tǒng)，那么視頻信號就格外顯得重要，那這種集成將會更加的深入、聯(lián)動關(guān)系將會更加的復(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，超過一定金額的政府項(xiàng)目是要舉行招標(biāo)活動的，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，絕對不允許一、兩家企業(yè)壟斷市場，但對于高鐵視頻監(jiān)控系統(tǒng)來講，集成商越少，兼容性、互聯(lián)互通性才會越好，才會有集中優(yōu)勢，不過八仙過海、各顯神通，每個集成商都想吃這塊大蛋糕，估計最終參與高鐵安防監(jiān)控的集成商絕對不是個位數(shù)，這也算是一種困局吧。
筆者說這么多的困局，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大一統(tǒng)的平臺、也希望高鐵系統(tǒng)能夠培養(yǎng)幾個大型的安防平臺集成商和運(yùn)營商，讓中國的解決方案提供商看到未來的希望，而不只是掌握在少數(shù)外資巨頭手里。
