I. Xav tau kev soj ntsuam thiab teeb lub hom phiaj
Kev tshaj tawm kev ua ub no feem ntau yog tsom rau ntawm cov chaw nkag hauv khw, atriums, lossis cov chaw tshaj tawm tshwj xeeb. Cov ntsiab lus hauv qab no yuav tsum tau txhais kom meej:
1. Lub Hom Phiaj Kev Ua Haujlwm: Cov khoom lag luam tshiab nce qib, kev muag khoom hnub so, cov khoom lag luam pom, lossis kev taw qhia cov neeg siv khoom.
2. Qhov chaw nyob: Qhov chaw teeb tsa qhov ntev, qhov chaw teeb pom kev zoo (hauv tsev / semi-sab nraum zoov), xav pom qhov deb thiab saib lub kaum sab xis.
3. Cov ntsiab lus hom: High-txhais cov yeeb yaj duab cov khoom, cov ntaub ntawv tshaj tawm kev tshaj tawm, cov ntxaij vab tshaus sib tham sib, lossis kev tshaj tawm nyob.
4. Kev siv nyiaj ntau: suav nrog cov khoom siv xauj tsev, kev teeb tsa thiab kev saib xyuas, thiab cov nqi tsim khoom tsim tau.
II. Cov Khoom Siv Xaiv thiab Cov Txheej Txheem Txheej Txheem
Xaiv qhov tsim nyog LED xauj tsev raws li kev tshaj tawm scenario:
1. Pixel Pitch (P-tus nqi): Rau cov khw muag khoom sab hauv tsev atriums lossis ze - thaj chaw saib ntau yam.
2. Brightness: Sab hauv ib puag ncig feem ntau xav tau 1500-2500 nits; yog tias thaj chaw muaj lub teeb ntuj muaj zog lossis yog ib puag ncig sab nraum zoov, xav tau ntau tshaj 3000 nits; tag nrho cov kev tshaj tawm sab nraum zoov xav tau qhov ci ntsa iab ntau dua 5000 cd / m³. 1 2
3. Kev Xam Xaj: Txiav txim siab qhov chaw tshuaj ntsuam raws li thaj chaw muaj nyob ntawm qhov chaw thiab qhov pom qhov pom qhov deb. Piv txwv li, yog tias cov neeg tuaj saib yog 10 meters los ntawm qhov screen hauv cheeb tsam atrium, nws raug nquahu tias thaj tsam ntawm qhov screen yuav tsum tsis pub tsawg tshaj 20 square meters, nrog rau qhov kev daws teeb meem tsawg kawg yog P4. 2
4. Refresh Rate thiab Xim: Ua si cov yeeb yaj kiab tshaj tawm kom zoo yuav tsum muaj qhov ua kom siab siab siab (Ntau dua lossis sib npaug rau 1920Hz) kom tsis txhob tua cov khoom cuav; ib chromaticity coordinate (Axy) Tsawg dua los yog sib npaug rau 0.003 yuav tsum tau ua kom cov xim sib xws . 1
III. Installation, Debugging, thiab On -Site Operation and Maintenance
1. Ntawm -Qhov Kev Tshawb Fawb: Paub meej txog cov qauv thauj khoom-cov kabmob muaj peev xwm ntawm qhov chaw teeb tsa, lub zog nkag mus rau cov ntsiab lus, thiab cov teeb liab kis tau tus mob los xyuas kom meej tias tsis muaj qhov cuam tshuam pom tom qab kev teeb tsa screen. 2
2. System Debugging: Txuas lub teeb liab qhov chaw (xws li lub computer, media player), sim cov duab ncaj ncees, brightness uniformity, thiab suab synchronization nyhuv, thiab ua kom tiav tsawg kawg yog ib tug tag nrho -function test. 2
3. Kev Tswj Cov Ntsiab Lus: Cov ntsiab lus tshaj tawm yuav tsum tau ua si hauv ntu ntawm lub sijhawm teem tseg, xws li kev hloov pauv ntawm cov yeeb yaj kiab cov khoom tshiab, cov ntawv luv luv, thiab sib tham sib QR cov lej. Kev hloov tshiab tuaj yeem ua rau lub sijhawm tiag tiag ntawm USB, network, lossis tswj software. 3
IV. Kev tswj hwm tus nqi thiab cov lus pom zoo
1. Cov Nqi Them Nqi: Cov nqi xauj tsev (xws li qhov loj me thiab lub sijhawm xauj tsev), nqi tsheb thauj mus los thiab kev teeb tsa, ntawm - tus nqi ntawm cov neeg ua haujlwm hauv chaw, thiab cov nqi tsim cov ntsiab lus ua tau. 2. Nqis - kev xaiv tau zoo: Tsis txhob nrhiav qhov loj tshaj plaws xwb; xaiv qhov tsim nyog pixel suab raws li qhov pom qhov deb yuav txuag tau tus nqi. Cov luv nqi feem ntau muaj rau kev xauj ntawm 3 hnub lossis ntau dua, thiab cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob bundling yuav ua rau muaj kev txuag nyiaj ntxiv.
