Raws li qhov nruab nrab tseem ceeb rau kev tshaj tawm cov ntaub ntawv hauv cov nroog niaj hnub no, cov khoom siv sab nraum zoov LED, nrog rau lawv cov ci ntsa iab, qhov pom dav dav, thiab cov khoom siv zoo, tau siv dav hauv kev lag luam tshaj tawm, kev taw qhia tsheb, kev tshaj tawm pej xeem, thiab lwm yam. Txawm li cas los xij, qhov nyuaj ntawm lawv cov kev teeb tsa thiab kev saib xyuas ncaj qha cuam tshuam rau lawv lub neej kev pabcuam thiab kev ua haujlwm zoo. Kab lus no piav qhia txog cov txheej txheem tseem ceeb ntawm sab nraum zoov LED qhia los ntawm kev pom kev, suav nrog qhov chaw xaiv thiab kev npaj, tsim qauv, txheej txheem kev teeb tsa, thiab cov tswv yim tu txhua hnub, txhawm rau muab kev siv rau cov kws tshaj lij kev lag luam.
Kev Xaiv Qhov Chaw Tshawb Fawb thiab Kev Ntsuam Xyuas Environmental
Qhov chaw teeb tsa ntawm lub teeb pom kev sab nraum zoov yuav tsum muaj kev saib xyuas zoo ntawm lub teeb pom kev zoo, kev khiav ceev, thiab lub tsev thauj khoom-cov kabmob. Ua ntej, zam qhov chaw uas muaj hnub ci ncaj qha (xws li phab ntsa ntsia lub hnub). Ntsuas lub teeb pom kev zoo nrog lub ntsuas hluav taws xob kom ntseeg tau tias cov teeb pom kev ci ntsa iab (feem ntau Ntau dua lossis sib npaug li 5000 nits) muaj 3: 1 rau ambient teeb piv kom pom kev pom. Qhov thib ob, qhov chaw yuav tsum nyob deb ntawm cov khoom siv uas muaj feem cuam tshuam rau electromagnetic cuam tshuam (xws li siab -voltage substations) thiab tso cai rau qhov chaw txaus rau cov cua sov dissipation (pom pom qhov deb ntawm ntau dua lossis sib npaug li 1 meter ntawm sab nraub qaum thiab phab ntsa). Tsis tas li ntawd, lub tsev qauv yuav tsum tiv taus qhov hnyav ntawm cov zaub (kwv yees li 30-50 kg ib square meter) thiab cua siab loads (cua qhov ntsuas ntsuas siab tshaj lossis sib npaug ntawm 12). Yog tias tsim nyog, lub koom haum tshaj lij yuav tsum ua qhov kev ntsuam xyuas kev nyab xeeb ntawm cov qauv.
Kev tsim qauv tsim thiab kev teeb tsa
1. Txawb thiab kev txhawb nqa
Sab nraum zoov cov khoom siv feem ntau siv cov khoom siv modular sib sau ua ke. Lub txee yuav tsum tau tsim los ntawm aluminium alloy lossis galvanized steel nrog kev ntsuas dej tsis zoo ntawm IP65 lossis siab dua, thiab cov khoom tsim ua - nyob rau hauv rwb thaiv tsev los tiv thaiv thermal deformation. Cov txheej txheem txhawb nqa muaj nyob rau hauv ob hom: kem-mounted (tsim rau standalone installation) thiab phab ntsa-mounted (txuas rau lub tsev phab ntsa). Cov qub yuav tsum tau muaj lub hauv paus pob zeb (qhov tob siab dua lossis sib npaug li 1.5 meters, qhov sib npaug ntawm qhov muaj zog ntau dua lossis sib npaug li 1.2%), thaum lub sijhawm tom kawg yuav tsum tau ntsuas tensile ntawm phab ntsa nto (ib zaug -taw tes load-cov kabmob muaj peev xwm ntau dua lossis sib npaug li 200 kg).
2. Cov kauj ruam txhim kho tseem ceeb
- Kev tsim kho lub hauv paus: Ua ntej txhim kho cov kab, theem hauv av thiab nrum lub pob zeb ua kom muaj zog. Qhov chaw kam rau ua ntawm cov khoom sib txuas yuav tsum tau tswj tsis pub dhau ± 5 hli.
- Steel Structure Assembly: Weld tus ncej steel raws li cov qauv kos duab, siv tus ntsuj plig qib los ntsuas qhov ntsug (kev sib txawv Tsawg dua lossis sib npaug li 1‰), thiab ua kev tiv thaiv xeb (txhaj tshuaj epoxy zinc- nplua nuj primer).
- Lub Rooj Sib Tham: Nruab lub LED modules ib qho los ntawm ib qho, siv dowel pins los tswj qhov sib nrug (flatness kam rau ua Tsawg dua lossis sib npaug li 0.5 hli). Tsis txhob khoov cov cables thaum txuas lawv.
- Kev sib txuas hluav taws xob: Cov kab hluav taws xob (AC 380V) thiab qis- cov kab hluav taws xob hluav taws xob (xws li HDMI / fiber ntau optic) tau muab tso rau nyias, nrog cov av tiv thaiv tsawg dua lossis sib npaug ntawm 4Ω. Lub surge protector (SPD) yuav tsum tau nruab.
Debugging thiab Performance Optimization
Tom qab kev teeb tsa, tag nrho qhov system debugging yuav tsum:
- Brightness thiab Xim Calibration: Siv cov cuab yeej tshwj xeeb los kho qhov sib xws, ua kom cov xim sib txawv ntawm cov pixels uas nyob ib sab yog tsawg dua 3 degree.
- Kev Ntsuas Cov Teeb Meem: Txheeb xyuas qhov video tawm tswv yim latency (tsawg dua lossis sib npaug li 50 milliseconds) thiab ntau -screen synchronization.
- Waterproofing Test: Simulate hnyav nag huab cua (txhaj tshuaj siab 0.1 MPa) thiab xyuas seb cov dej xau ntawm cov pob qij txha.
Kev tu txhua hnub thiab kev daws teeb meem
1. Kev tu ncua sij hawm
- Kev tu thiab tu: Tshem cov plua plav txhua hli nrog txhuam txhuam. So lub module nto nrog ib tug nruab nrab detergent (tsis txhob siv cawv) peb lub hlis twg.
- Kev soj ntsuam kho vajtse: Tshawb xyuas lub zog hluav taws xob (tso zis hluav taws xob hloov pauv tsawg dua lossis sib npaug li ± 5%) thiab lub davhlau ya nyob twg thaiv rau oxidation txhua rau lub hlis, thiab ceev cov bolts.
- Txhim kho Software: Tsis tu ncua hloov kho daim npav tswj hwm firmware txhawm rau txhim kho cov teeb meem kev sib raug zoo.
2. Kev daws teeb meem kev daws teeb meem
- Dub los yog distorted screen: Ua ntej xyuas lub hwj chim mov stability, ua raws li tsis zoo teeb liab cable kev twb kev txuas los yog graphics card tsav tsheb anomalies;
- Ib nrab LED tuag lub teeb: Tom qab nrhiav qhov tsis raug module, hloov nws nrog ib qho khoom seem thiab sau cov ntaub ntawv ntawm LED nti;
- Kev ua kom txias tsis ua haujlwm: ntxuav lub kiv cua lim. Yog hais tias qhov kub ntawm qhov kub ntawm qhov kub siab tshaj 40 degrees, nruab ib lub tshuab cua txias lossis dej txias.
Xaus
Kev ua haujlwm tau zoo ntawm sab nraum zoov LED qhia nyob ntawm kev tshawb fawb txog kev teeb tsa thiab kev saib xyuas tus qauv. Cov kws tshaj lij kev lag luam yuav tsum ua raws li cov qauv kev lag luam nruj me ntsis (xws li GB / T 29742-2013 General Specification for Light-Emitting Diode (LED) Displays) thiab txhim kho cov kev daws teeb meem raws li cov xwm txheej tshwj xeeb kom ntseeg tau tias muaj kev ntseeg siab thiab pom kev ua tau zoo hauv qhov chaw sab nraum zoov. Nyob rau hauv lub neej yav tom ntej, nrog kev siv dav dav ntawm Mini / Micro LED thev naus laus zis, lub teeb yuag thiab kev tswj hwm lub zog ntawm cov khoom siv sab nraum zoov yuav dhau los ua cov txheej txheem tshiab.
