Gtus tswv tsev kov, lossis kov npo npuas, hais txog qhov tshwm sim uas ib qho khoom siv touchscreen zoo nkaus li kov inputs ntawm nws tus kheej, nyob rau hauv lwm yam lus, touchscreen ua hauj lwm yeej tsis muaj kev sib cuag nrog lub cev.

Qhov no tuaj yeem ua rau qhov tsis xav tau ua rau ntawm lub cuab yeej, xws li cov apps qhib lossis kaw, thiab ntaus ntawv.

Lo lus "dab kov" yog coj los ntawm vim tias cov khoom nkag tau los ntawm "dab" lossis qhov tsis pom, tsis yog los ntawm tus neeg siv txhob txwm kov lub vijtsam.Nws tuaj yeem tshwm sim los ntawm ntau yam, suav nrog, teeb meem hauv av, software glitches, hardware malfunctions, lossis ib puag ncig yam xws li hluav taws xob zoo li qub lossis noo noo.

Hauv tsab xov xwm no, peb yuav sau tag nrho cov ua tau raws li qhov ua tau thiab pab koj daws teeb meem.

Koj tuaj yeem tshem tawm feem ntau ntawm cov teeb meem lossis ua rau ob peb kauj ruam hauv 30 feeb ntawm koj tus kheej.

 

1. Tsis muaj av lossis tsis muaj av.

Thaum lub touchscreen tsis nyob hauv av, nws tuaj yeem tsim cov nqi hluav taws xob, cuam tshuam nrog lub peev xwm ntawm lub cuab yeej los ntes cov khoom siv kov.Qhov no tuaj yeem tshwm sim thaum lub kiosk tsis zoo sib sau ua ke, lossis yog tias lub tshuab hauv av puas los yog txiav tawm lub sijhawm.

Yuav kuaj li cas

Txoj kev raug thiab ua tau zoo tshaj plaws yog siv lub tshuab multimeter, uas ntsuas cov khoom hluav taws xob zoo li qhov hluav taws xob, kev tiv thaiv, thiab txuas ntxiv.Nov yog cov kauj ruam mus:

1. Tua lub touchscreen, PC thiab tag nrho cov khoom siv txuas nrog, thiab tshem tawm ntawm lub hwj chim.

2. Teem lub multimeter rau qhov tsis kam (ohm) teeb tsa.

3. Kov ib qho kev sojntsuam ntawm multimeter mus rau cov hlau chassis ntawm lub touchscreen (hlau) rooj plaub.

4. Kov lwm qhov kev sojntsuam ntawm lub multimeter mus rau ib qho khoom siv hauv av, xws li cov kav dej hlau lossis hauv av ntawm lub qhov hluav taws xob.Xyuas kom tseeb tias cov khoom hauv av tsis nyob rau hauv kev sib cuag nrog lub touchscreen.

5. Lub multimeter yuav tsum nyeem qhov tsis muaj zog, feem ntau tsawg dua 1 ohm.Qhov no qhia tau hais tias cov ntaub ntawv PC yog tsim nyog.

Yog hais tias lub multimeter nyeem ib qho kev tiv thaiv siab los yog tsis muaj kev txuas ntxiv, nws qhia tau tias yuav muaj teeb meem nrog cov av.

Yog hais tias koj nrhiav tsis tau ib tug multimeter nyob ze koj, tseem muajLwm txoj hauv kev los ntsuas qhov grounding:

Tua tag nrho cov kiosks lossis cov cuab yeej ze ze ntawm lub vijtsam, thiab txo hwj chim.Txuas lub hwj chim nrog lub touchscreen mus rau lwm qhov chaw hauv av, thiab txuas lub monitor USB rau lwm lub laptop lossis PC.Thiab xyuas seb nws puas daws qhov teeb meem dab kov.

Nyob rau hauv rooj plaub no, nws yuav pab tau hu rau tus kws tshaj lij lossis tus kws tshaj lij hluav taws xob kom pab txheeb xyuas thiab daws qhov teeb meem.

Nws yog ib qho tseem ceeb los xyuas kom meej tias lub touchscreen yog qhov zoo hauv av kom tsis txhob muaj hluav taws xob txaus ntshai thiab ua kom muaj kev nyab xeeb thiab txhim khu kev qha.

 

2. Cov khoom tsis xav tau ntawm qhov screen

Dej, dej ntub dej hnyav thiab lwm yam khoom tau txuas nrog rau qhov screen (touchscreen) thaj tsam ntawm tus saib yuav hu dab kov.

Yuav kho li cas :

Nws yog ib qho yooj yim: tshem tawm cov khoom tsis huv xws li dej los yog ntxuav lub iav touchscreen thiab saib xyuas qhov chaw, thiab xyuas seb puas tseem muaj cov khoom uas tau txuas thiab xyuas dua tom qab tshem tawm.

 

3. Software glitches

Sim tshem tag nrho cov keeb kwm yav dhau los khiav app.raws li qhov ua tau, lossis tua thiab rov ua dua ntawm koj lub touchscreen kom paub tseeb tias muaj teeb meem software.

 

4. Cov hluav taws xob zoo li qub lossis cuam tshuam

Xyuas seb qhov kov USB cable cuam tshuam nrog lwm cov cables txuas nrog lub computer.Lub kov USB cable yuav tsum yog ntawm nws tus kheej los yog sib cais

Tshawb xyuas lub nraub qaum ntawm cov khoom siv kov rau qhov chaw muaj zog sib nqus, tshwj xeeb tshaj yog ntug ntawm tus kov tswj,

Yuav kho li cas:

Yog tias koj txhawj xeeb txog txhua yam kev cuam tshuam, nws raug nquahu kom koj disassemble lub touchscreen vaj huam sib luag los yog saib xyuas thiab ua lwm yam kev sim hauv ib puag ncig yooj yim dua.Yog tias koj tuaj yeem txav los yog nyob deb ntawm koj tus kheej los ntawm kev cuam tshuam, nws yog ib qho teeb meem yooj yim los daws.Txawm li cas los xij, yog tias koj tsis tuaj yeem hloov koj ib puag ncig, nws yog qhov zoo tshaj plaws los tiv tauj koj tus khub touchscreen daws, saib seb puas muaj cov kev daws teeb meem los txhim kho kev cuam tshuam kev cuam tshuam.

Horsent, raws li tus neeg muag khoom muaj txiaj ntsig touchscreen, muaj kev paub dhau los hauv kev muab cov kev daws teeb meem los txhim kho kev cuam tshuam kev cuam tshuam los ntawm software thiab kho vajtse.

 

5. Touchscreen teeb tsa

Yog lawm, touchscreen cov kev pab cuam teeb meem tuaj yeem ua rau ib yam, hu rau kojtus neeg muag khoom ntawm lub touchscreenlos yog IC tus neeg muag khoom rau kev pab hloov kho lossis rov qab mus rau lub Hoobkas.

 

6. Hloov tus maub los

Qhov no yog cov kauj ruam kawg uas yuav dhau mus tsuas yog tias cov kauj ruam saum toj no tsis ua haujlwm thiab koj tus neeg muag khoom qhia rau koj tias lub touchscreen maub los yuav puas.

Siv lwm yam khoom siv uas tsis muaj kev tiv thaiv los ntawm tib yam khoom, txhawm rau txheeb xyuas qhov ua tau yog tias ua tau.Yog tias cov lus teb yog, Xyuas seb koj lub touchscreen puas tseem nyob hauv warranty kom txuag tau qee cov nqi kho.

 

Finally, tsis muaj yuav tsum tauntshai txog Touchscreen ghosts kov, feem ntau qhov laj thawj tuaj yeem txheeb xyuas thiab koj tuaj yeem rov pib koj txoj haujlwm hauv ob peb feeb.

Ua ntej yuav tsiv mus rau qib 5 thiab 6, tiv tauj koj lub chaw muag khoom lossis cov kws tshaj lij rau kev pab.
