通过户外LED屏租赁, 我们可以看到其在各个领域的广泛应用,为活动和场合营牠独.
一,项目背景与需求定位
Nyob rau hauv lub teeb, LED显示屏作为信息传播与品牌展示的核心载体，其安装方案的科学性爴接影瞔使本方案针对商业综合体, 写字楼或酒店类商用大厦的LED , 结合建筑结构特征，商业运营场景及视觉传播目标，从系统选型，结构设述到维进行全流程规划, 确保显示屏在稳定性, 显示效果与安全合规性上达到商甇纨
2,系统方案设计
(一)显示系统选型
1.屏体类型与像素间距
根据安装场景(室内/室外)与观看需求,室外大屏建议采用
P4-P6像素间距的全彩LED 模组(若观看距离 Less than los sib npaug 10 Daim duab, 可选用P3及以下间距提升清晰度); 室内场景(如大堂,电梯厅) 推荐P2-P3间距的如堂屏, 兼顾细腻度与节能性.
某18米宽x6米高的室外墙面为例:选用P5模组时,分辦率为3600点(宽) × 1200点(1酹), 2需扫驱动方式保障刷新率(Ntau dua lossis sib npaug rau 1920Hz), 避免拍摄频闪.
2.亮度与防护等级
室外屏需满足5000-8000cd/m亮度(支持自动光感调节, 根据环境光切换节能/高岺), Ntau dua lossis sib npaug IP65(模组灌胶工艺＋防水箱体设计);室内屏亮度控制在{2}}cd/m', 防护等级 IP30即可, 重点优化色彩还原度(色域覆盖率 Ntau dua lossis sib npaug rau 90% NTSC).
(2)控制系统架构
1.控制方式选择
采用同步+异步双模式控制系统: 日常商业广告, 活动直播等实时内制系统MSD300) Cov ntaub ntawv pov thawj, cov ntaub ntawv pov thawj上可通过异步控制卡(如卡莱特A8)离线存储播放,提升系统可靠性.
Los ntawm kev xauj tsev LED sab nraum zoov, peb tuaj yeem pom lawv daim ntawv thov dav hauv ntau qhov chaw, tsim kom muaj lub suab tshwj xeeb - pom kev rau cov xwm txheej thiab lub sijhawm.
I. Project Background thiab Requirements
Hauv kev lag luam kev lag luam, cov ntxaij vab tshaus LED ua haujlwm tseem ceeb rau kev tshaj tawm cov ntaub ntawv thiab cov khoom lag luam. Kev tsim qauv ntawm lawv cov kev teeb tsa ncaj qha cuam tshuam rau lawv cov txiaj ntsig thiab kev ua haujlwm muaj txiaj ntsig. Qhov kev daws teeb meem no hais txog kev tsim kho ntawm LED zaub screen kev xav tau ntawm kev lag luam complexes, chaw ua hauj lwm vaj tse, los yog tsev so, combining architectural structural yam ntxwv, coj mus muag scenarios, thiab kev sib txuas lus lub hom phiaj. Nws muab cov phiaj xwm dav dav los ntawm kev xaiv cov txheej txheem thiab cov qauv tsim rau kev tsim kho thiab kev ua haujlwm thiab kev saib xyuas, kom ntseeg tau tias lub vijtsam zaub ua tau raws li kev lag luam- cov qauv qib hauv cov ntsiab lus ntawm kev ruaj ntseg, cov txiaj ntsig pom, thiab kev ua raws li kev nyab xeeb.
II. System Solution Design
(I) Kev Xaiv Qhov System
1. Hom npo thiab Pixel Pitch
Raws li kev teeb tsa kev teeb tsa (hauv tsev / sab nraum zoov) thiab saib cov kev xav tau, sab nraum zoov cov ntxaij vab tshaus loj tau pom zoo kom siv tag nrho - xim LED modules nrog pixel suab ntawm P4-P6 (yog tias qhov pom qhov deb tsawg dua lossis sib npaug li 10 meters, P3 lossis me pixel suab tuaj yeem siv los txhim kho kom pom tseeb); rau cov xwm txheej sab hauv tsev (xws li chaw tos txais thiab cov chaw ua haujlwm of elevator), cov ntxaij vab tshaus me me nrog lub suab ntawm P2-P3 raug pom zoo, ntsuas qhov zoo thiab lub zog ua haujlwm.
Siv cov phab ntsa sab nraum zoov ntsuas 18 meters dav x 6 meters siab ua piv txwv: siv P5 module, qhov kev daws teeb meem yog 3600 pixels (dav) × 1200 pixels (qhov siab), xav tau 1/32 scan tsav txoj kev los xyuas kom meej tus nqi refresh (Ntau dua lossis sib npaug rau 1920Hz) thiab tsis txhob flicker thaum ua yeeb yaj kiab.
2. Kev ci ntsa iab thiab kev tiv thaiv qib
Sab nraum zoov cov ntxaij vab tshaus yuav tsum tau ua kom tau raws li qhov ci ci ntawm 5000-8000 cd / m² (txhawb kev hloov pauv tsis siv neeg lub teeb pom kev, hloov ntawm lub zog- txuag / siab-brightness hom raws li ambient lub teeb), thiab kev tiv thaiv qib siab dua lossis sib npaug ntawm IP65 (cov txheej txheem potting + waterproof casing tsim); Cov ntxaij vab tshaus sab hauv tsev yuav tsum muaj qhov ci ntsa iab tswj ntawm 800-1500 cd / m², thiab qib kev tiv thaiv ntawm IP30 txaus, nrog rau kev tsom mus rau kev tsim cov xim zoo nkauj (xim gamut kev pab ntau dua lossis sib npaug rau 90% NTSC). (II) Control System Architecture
1. Tswj txoj kev xaiv
Ib tug dual- hom kev tswj qhov system sib txuas synchronous thiab asynchronous tswj tau txais yuav: Real- cov ntsiab lus sijhawm xws li kev tshaj tawm kev lag luam niaj hnub thiab kev tshaj tawm hauv xov xwm tau txuas ncaj qha rau cov khoom siv rov qab los ntawm daim npav tswj hwm synchronous (xws li Nova MSD300) kom tsis txhob ncua sijhawm ntawm cov zaub; Cov ntawv ceeb toom xwm txheej ceev thiab cov lus hais ruaj khov tuaj yeem khaws cia thiab ua si offline los ntawm daim npav tswj hwm asynchronous (xws li Colorlight A8), txhim kho kev ntseeg tau.
