Yuav kho tej yam me me no li cas?
Ua ntej, npaj cov cuab yeej tu.Tsib yam khoom tseem ceeb rauLED zaub screenCov neeg ua haujlwm saib xyuas yog cov tweezers, rab phom cua kub, cov hlau soldering, multimeter, thiab daim npav xeem.Lwm cov ntaub ntawv pabcuam suav nrog cov tshuaj txhuam hniav (xaim), soldering flux, tooj liab hlau, kua nplaum, thiab lwm yam.
1 、 Qhov teeb meem ntawm kab ntsig
"Caterpillar" tsuas yog ib lo lus piv txwv, xa mus rau qhov tshwm sim ntawm qhov ntev tsaus nti thiab ci ntsa iab tshwm ntawm qee qhov LED cov ntxaij vab tshaus nyob rau hauv lub zog tsis muaj qhov chaw nkag, feem ntau yog xim liab.Lub hauv paus ua rau ntawm qhov tshwm sim no yog qhov xau ntawm cov nti sab hauv ntawm lub teeb, lossis luv luv ntawm IC deg Circuit Court tom qab nws, nrog rau cov qub yog feem ntau.Feem ntau, thaum qhov xwm txheej no tshwm sim, peb tsuas yog yuav tsum tuav rab phom cua kub thiab tshuab cua kub raws li qhov tsis muaj xim "cav" uas yog hluav taws xob xau.Thaum peb tshuab nws mus rau qhov teeb meem teeb meem, nws feem ntau yog OK vim hais tias qhov kev sib txuas ntawm cov xau sab hauv yog tawg vim cua sov, tab sis tseem muaj qhov tsis txaus ntshai.Peb tsuas yog yuav tsum tau nrhiav cov hlaws tawg LED thiab hloov nws raws li txoj kev hais saum toj no.Yog hais tias muaj ib tug luv luv Circuit Court nyob rau hauv lub rov qab IC nto, nws yog tsim nyog los siv ib tug multimeter los ntsuas qhov cuam tshuam IC pin Circuit Court thiab hloov nws nrog ib tug tshiab IC.
2, Hauv zos "tuag teeb" teeb meem
Local "tuag teeb" hais txog ib lossis ob peb lub teeb ntawm lubLED zaub screenuas tsis teeb.Hom tsis teeb no yog qhov txawv raws li lub sijhawm tsis muaj teeb pom kev zoo thiab ib nrab xim tsis teeb.Feem ntau, qhov teeb meem no yog vim muaj teeb meem nrog lub teeb nws tus kheej, txawm tias ntub los yog RGB nti puas lawm.Peb txoj kev kho yog yooj yim, uas yog los hloov nws nrog lub Hoobkas muab LED hlaws khoom seem.Cov cuab yeej siv yog tweezers thiab phom cua kub.Tom qab hloov cov hlaws LED seem, Rov ua dua nrog daim npav xeem, thiab yog tias tsis muaj teeb meem, nws twb kho lawm.
3 、 Hauv zos xim thaiv qhov teeb meem ploj lawm
Cov phooj ywg uas paub txog LED zaub cov ntxaij vab tshaus tau pom qhov teeb meem zoo li no, uas yog tias thaum lub vijtsam LED ua si ib txwm muaj, muaj qhov me me square zoo li xim thaiv.Qhov teeb meem no feem ntau yog tshwm sim los ntawm kev kub hnyiab ntawm cov xim IC tom qab tswj thaiv.Qhov kev daws teeb meem yog hloov nws nrog IC tshiab.
4 、 Local garbled code teeb meem
Qhov teeb meem ntawm cov cim garbled hauv zos yog qhov nyuaj heev, hais txog qhov tshwm sim ntawm random flickering ntawm cov xim blocks hauv qee qhov chaw ntawm LED cov ntxaij vab tshaus thaum lub sijhawm ua si.Thaum qhov teeb meem no tshwm sim, peb feem ntau yog thawj zaug tshawb xyuas qhov teeb meem kev sib txuas ntawm cov teeb liab cable.Peb tuaj yeem tshawb xyuas seb lub ribbon cable puas tau tawg, seb lub network cable puas xoob, thiab lwm yam.Hauv kev saib xyuas, peb pom tias cov khoom siv aluminium magnesium hlau yog qhov ua rau kub hnyiab, thaum cov hlau ntshiab tooj liab muaj lub neej ntev dua.Yog tias tag nrho cov teeb liab kev sib txuas raug kuaj xyuas thiab tsis muaj teeb meem, ces swapping lub faulty LED module nrog rau qhov chaw ua si ib txwm nyob ib sab tuaj yeem txiav txim siab seb puas muaj peev xwm ua tau tias LED module sib raug rau qhov chaw ua si txawv txav puas.Qhov ua rau muaj kev puas tsuaj feem ntau yog teeb meem IC, thiab kev saib xyuas thiab kev tuav tau yuav nyuaj heev.Peb yuav tsis piav qhia txog qhov xwm txheej ntawm no.
5 、 Ib feem ntawm lub vijtsam dub lossis thaj chaw loj dub teeb meem
Feem ntau muaj ntau yam sib txawv uas tuaj yeem ua rau qhov tshwm sim no.Peb yuav tsum tshawb xyuas thiab daws qhov teeb meem los ntawm cov txheej txheem tsim nyog thiab cov kauj ruam.Feem ntau, muaj plaub lub ntsiab lus uas tuaj yeem ua rau lub vijtsam dub ntawm tib lub vijtsam LED, uas tuaj yeem tshawb xyuas ib qho los ntawm ib qho:
1 、 Lub kaw lus xoob
(1) Ua ntej, xyuas thiab paub meej tias seb cov kab hluav taws xob siv los txuas rau tus tswj yog xoob, txawv txav, lossis raug tshem tawm.Yog tias nws tig dub thaum pib ntawm cov txheej txheem thauj khoom, nws yuav yog vim muaj cov kab sib txuas lus xoob cuam tshuam cov txheej txheem kev sib txuas lus, ua rau lub vijtsam tig dub.Tsis txhob yuam kev tias lub vijtsam lub cev tsis tau txav mus, thiab txoj kab tsis tuaj yeem xoob.Thov xyuas koj tus kheej ua ntej, uas yog qhov tseem ceeb rau kev daws teeb meem sai
(2) Tshawb xyuas thiab paub meej tias puas yog lub HUB faib pawg txuas nrog lub vijtsam LED thiab daim npav tswj lub ntsiab yog nruj nreem txuas thiab ntxig rau sab saud.
2 、 Qhov teeb meem ntawm kev siv fais fab
Thov xyuas kom meej tias tag nrho cov khoom siv kho vajtse, suav nrog cov kev tswj hwm, yog siv tau zoo.Puas yog lub teeb hluav taws xob flashing lossis puas muaj teeb meem hauv cov khoom siv hluav taws xob?Nws yog ib qho tsim nyog sau cia tias kev siv lub tshuab hluav taws xob tsis zoo yog feem ntau ua rau qhov tshwm sim no
3, Kev sib txuas teeb meem nrog LED chav tsev board
(1) Ob peb lub rooj sib law liag tsis teeb nyob rau hauv txoj kab ntsug.Xyuas seb lub hwj huam mov rau kab ntawv no puas zoo li qub
(2) Ob peb lub rooj sib law liag tsis teeb nyob rau hauv txoj kab rov tav.Xyuas seb qhov kev sib txuas ntawm cable ntawm lub rooj tsavxwm ib txwm muaj thiab lub rooj tsav xwm txawv txav txuas nrog;Los yog chip 245 ua haujlwm zoo
4 、 Software nqis los yog teeb meem teeb lub raj
Yog hais tias muaj ib tug meej ciam teb ntawm ob, muaj peev xwm ntawm software los yog chaw ua rau nws yog siab;Yog tias muaj kev hloov pauv ntawm ob qho tib si, nws yuav muaj teeb meem nrog lub teeb lub raj.
