在這些(xie)液晶拼接大屏幕顯示(shi)系統(tong)通過(guo)分布(bu)(bu)式架構部署、可(ke)以輕松地實現超高(gao)清(qing)采集、無壓縮傳輸、高(gao)還原清(qing)晰顯示(shi)各個(ge)系統(tong)的(de)(de)(de)信息(xi),從而達到(dao)在全面實時觀(guan)看和掌握各方面信息(xi)的(de)(de)(de)同時還在提高(gao)指揮調(diao)度和決策的(de)(de)(de)效率和準確(que)性、信息(xi)資源發布(bu)(bu)的(de)(de)(de)便捷性、故障預警的(de)(de)(de)及時性。
一、什么是分布式矩陣,分布式矩陣如何構建液晶拼接墻顯示系統
傳統(tong)(tong)(tong)(tong)(tong)(tong)矩(ju)陣(zhen)在(zai)應對(dui)多(duo)(duo)(duo)個(ge)(ge)站(zhan)(zhan)(zhan)(zhan)點(dian)的(de)(de)時候只能(neng)是(shi)每(mei)(mei)個(ge)(ge)站(zhan)(zhan)(zhan)(zhan)點(dian)安(an)放一(yi)(yi)(yi)個(ge)(ge)矩(ju)陣(zhen)、在(zai)需要統(tong)(tong)(tong)(tong)(tong)(tong)一(yi)(yi)(yi)調(diao)度(du)時每(mei)(mei)一(yi)(yi)(yi)個(ge)(ge)站(zhan)(zhan)(zhan)(zhan)點(dian)都(dou)要安(an)排人進(jin)行手(shou)動的(de)(de)矩(ju)陣(zhen)切(qie)換(huan),而分布(bu)式(shi)(shi)矩(ju)陣(zhen)則是(shi)將所有的(de)(de)站(zhan)(zhan)(zhan)(zhan)點(dian)變成一(yi)(yi)(yi)個(ge)(ge)整體矩(ju)陣(zhen)、可(ke)以(yi)在(zai)中心站(zhan)(zhan)(zhan)(zhan)點(dian)切(qie)換(huan)所有站(zhan)(zhan)(zhan)(zhan)點(dian)的(de)(de)視頻和節目(mu)源或實(shi)現(xian)(xian)各點(dian)的(de)(de)實(shi)時控(kong)(kong)(kong)制(zhi)(zhi)、授(shou)權控(kong)(kong)(kong)制(zhi)(zhi)、定時切(qie)換(huan)、預(yu)案式(shi)(shi)切(qie)換(huan)、使眾(zhong)多(duo)(duo)(duo)站(zhan)(zhan)(zhan)(zhan)點(dian)真(zhen)正成為(wei)(wei)智能(neng)站(zhan)(zhan)(zhan)(zhan)點(dian)。其以(yi)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)(tong)工(gong)程、信息(xi)科學、自動控(kong)(kong)(kong)制(zhi)(zhi)理論等為(wei)(wei)指(zhi)導(dao)、以(yi)行業(ye)客戶需求為(wei)(wei)背景將先進(jin)可(ke)靠(kao)的(de)(de)信號采集(ji)與傳輸技(ji)術、音視頻編(bian)解(jie)碼(ma)技(ji)術、圖(tu)形(xing)信號轉換(huan)技(ji)術、多(duo)(duo)(duo)屏(ping)圖(tu)像處理技(ji)術、網絡(luo)通信技(ji)術、智能(neng)控(kong)(kong)(kong)制(zhi)(zhi)技(ji)術等融(rong)合為(wei)(wei)一(yi)(yi)(yi)體,為(wei)(wei)用戶提供一(yi)(yi)(yi)個(ge)(ge)具有高物(wu)理分辨率、高清晰度(du)、高智能(neng)化控(kong)(kong)(kong)制(zhi)(zhi)、高穩定性的(de)(de)大流(liu)量圖(tu)形(xing)信息(xi)處理終端:液晶拼(pin)接墻分布(bu)式(shi)(shi)視頻矩(ju)陣(zhen)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)(tong)能(neng)夠很好(hao)地與用戶監控(kong)(kong)(kong)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)(tong)、指(zhi)揮調(diao)度(du)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)(tong)、網絡(luo)信息(xi)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)(tong)、信息(xi)發布(bu)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)(tong)、視頻會(hui)議系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)(tong)、工(gong)業(ye)生產控(kong)(kong)(kong)制(zhi)(zhi)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)(tong)、報警系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)(tong)、會(hui)議錄播系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)(tong)、中控(kong)(kong)(kong)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)(tong)等連結集(ji)成,并(bing)且可(ke)對(dui)不同類型的(de)(de)信號實(shi)現(xian)(xian)兼容(rong)采集(ji)從而形(xing)成一(yi)(yi)(yi)套功能(neng)完(wan)善(shan)、技(ji)術先進(jin)、操作方便的(de)(de)交互式(shi)(shi)圖(tu)形(xing)信息(xi)處理及管(guan)理平臺。
二、分布式矩陣優勢解析
1、網(wang)絡化、數(shu)(shu)字化:液晶拼接大屏幕分布(bu)式矩陣采用業(ye)界最先(xian)進(jin)(jin)的(de)分布(bu)式處理架構、將各種類(lei)型的(de)音(yin)視頻信號進(jin)(jin)行獨立(li)的(de)網(wang)絡化、數(shu)(shu)字化編碼(ma)、傳輸(shu)并(bing)進(jin)(jin)行解碼(ma)顯示:從根(gen)本上(shang)解決(jue)了(le)傳統方案的(de)信號噪聲干擾、遠距(ju)離傳輸(shu)衰減、信號質量(liang)下降等技術難點,并(bing)且采用分布(bu)式、節點化的(de)軟(ruan)硬(ying)件設計使得系(xi)統性能和穩定性都大幅(fu)提高。
2、超強(qiang)信號顯(xian)(xian)示(shi)能力:可實(shi)現所有信號源的接入(ru)管(guan)理、上屏顯(xian)(xian)示(shi),在液晶拼接墻顯(xian)(xian)示(shi)屏幕上可實(shi)現圖像的無(wu)限自(zi)由拉伸(shen)、壓縮(suo)、跨屏、漫游、疊加、畫中畫、畫外畫、并且每個解碼處理單元最高(gao)可達1920×1080全高(gao)清輸出(chu)。
3、豐富(fu)的信號源類(lei)型基本上涵(han)蓋了目前市面(mian)上幾乎所有的類(lei)型:其輸(shu)入信號包括(kuo)CVBS、YPBPR、VGA、HDMI、DVI、DVI PLUS、DVI(HDCP)、3G-SDI、HD-SDI、HDBaseT、Fiber等(deng);輸(shu)出信號則包含VGA、HDMI、DVI、DVI、3G-SDI、HDBaseT、Fiber等(deng)、在(zai)一定程度上真正的實現了數模高清(qing)信號任意組合(he)切換、并且(qie)每個通(tong)道可配置不同的分辨率(lv)。
4、采用純硬件板(ban)卡(ka)(ka)(ka)式單路(lu)單卡(ka)(ka)(ka)結構單路(lu)板(ban)卡(ka)(ka)(ka)式設計(ji)、安裝靈活方便,其輸入(ru)輸出(chu)板(ban)卡(ka)(ka)(ka)、控制卡(ka)(ka)(ka)等主(zhu)要(yao)模(mo)塊均為插卡(ka)(ka)(ka)方式設計(ji):并且擁有多種(zhong)接(jie)口信號格式混入(ru)混出(chu)等功(gong)能,其中(zhong)單卡(ka)(ka)(ka)單通道設計(ji)可支(zhi)持(chi)8×8、18×18、36×36、72×72、144X144等多類型多路(lu)數信號的配置規模(mo)。
5、矩(ju)陣采用分布(bu)式、節(jie)點(dian)化的設計方(fang)案、在一(yi)定程度上(shang)提高了液晶(jing)拼接墻顯示系統的穩定性,并且單點(dian)故(gu)障對整個大(da)屏幕顯示系統而(er)(er)言并無(wu)多(duo)大(da)的影響、而(er)(er)且相對于傳統PC架構控(kong)制(zhi)系統而(er)(er)言其在真正(zheng)意義(yi)上(shang)實現熱(re)插拔(ba)、低功耗、節(jie)能環(huan)保、安全可靠;
當然、分(fen)布(bu)式(shi)矩陣(zhen)的優點(dian)遠非以上(shang)幾點(dian),還有(you)一些(xie)(xie)小編就不在(zai)(zai)這(zhe)一一列舉了。但就液晶拼(pin)接(jie)屏(ping)的用(yong)戶而言(yan)、能夠了解清楚以上(shang)幾點(dian)就足以滿足其選(xuan)購分(fen)布(bu)式(shi)矩陣(zhen)了。除(chu)了在(zai)(zai)液晶拼(pin)接(jie)墻顯(xian)示系統中(zhong)會(hui)使(shi)用(yong)到分(fen)布(bu)式(shi)矩陣(zhen)外(wai)在(zai)(zai)一些(xie)(xie)多媒(mei)體系統中(zhong)也能看見其身影。
