Txawm hais tias muaj ntau yam2D barcode scannerstam sim no tswj hwm qhov zoo dua, tab sis hauv qee qhov kev siv cov xwm txheej, 1D barcode scanners tseem nyob hauv txoj haujlwm uas tsis tuaj yeem hloov pauv. Txawm tias feem ntau ntawm cov1D barcode phomyog txhawm rau luam theej duab daim ntawv, tab sis txhawm rau ua kom tau raws li cov kev them nyiaj mobile nrov tam sim no, muaj qee cov qauv ntawm 1D CCD bar code scanner phom kuj tau pib muaj txoj haujlwm ntawm kev xa xov tooj ntawm tes thiab lwm yam khoom siv hluav taws xob.
1.Dab tsi yog 1D lub teeb liab barcode scanner?
1D barcodes yog ib qho qauv uas muaj cov kab ib sab thiab qhov chaw, thiab ntau hom muaj xws li EAN-13, CODE39, CODE128, thiab lwm yam.
Lub hauv paus ntsiab lus ntawm CCD scanning thev naus laus zis yog siv lub teeb liab teeb liab rau irradiate barcode, barcode qhia txog lub teeb liab, thiab lub scanner pom qhov hloov ntawm lub teeb pom kev los ntawm photoelectric sensor, thiab tom qab ntawd txiav txim siab cov ntaub ntawv ntawm barcode. Lub teeb liab scanning tshuab yog ceev, raug thiab ruaj khov, thiab haum rau ntau qhov chaw ua haujlwm.
1D CCD barcode scanner muaj ntau yam kev siv hauv ntau yam lag luam. Hauv kev lag luam muag khoom, nws tuaj yeem siv rau kev muag khoom, kev tswj cov khoom muag thiab kev luam ntawv daim ntawv lo. Hauv logistics thiab warehouses, nws tuaj yeem tshawb xyuas sai thiab taug qab cov khoom. Hauv kev kho mob, tsev qiv ntawv thiab lwm qhov chaw, nws tuaj yeem siv los taug qab thiab tswj cov khoom. Ntxiv rau,1D CCD barcode scannersua lub luag haujlwm tseem ceeb hauv kev tsim khoom, kev thauj mus los, kev nyab xeeb khoom noj thiab lwm yam lag luam. Nws txhim kho kev ua haujlwm zoo, txo qhov ua yuam kev ntawm kev ua haujlwm ntawm phau ntawv thiab txhim kho kev ua haujlwm tag nrho.
2.Cov yam ntxwv thiab cov kev sib tw ntawm cov lej tshuaj ntsuam
2.1. Ib qho screen code yog hom tshwj xeeb ntawm QR code uas tso tawm rau ntawm lub vijtsam ntawm lub tshuab hluav taws xob. Nws tuaj yeem luam tawm los nyeem cov ntaub ntawv QR code ntawm qhov screen. Screen Code muaj ntau yam ntawm daim ntawv thov scenarios, suav nrog e-payment, e-ticketing, e-kev txheeb xyuas tus kheej thiab lwm yam. Piv txwv li, kev them nyiaj yog ua los ntawmluamqhov screen code ntawm lub xov tooj ntawm tes, los yog kev nkag mus pov thawj yog tsim los ntawm scanning lub screen code ntawm e-tib daim pib.
2.2. Cov yam ntxwv tseem ceeb ntawm kev tshuaj ntsuam cov lis dej num muaj xws li qhov sib txawv me me, kev xav txog thiab teeb meem refraction, thiab lwm yam.
Kev sib piv qis: Txij li cov zaub ntawm QR cov lej ntawm lub vijtsam raug txwv los ntawm qhov ci thiab qhov sib piv ntawm lub vijtsam, qee zaum qhov sib piv dub thiab dawb ntawm QR cov lej qis, ua rau nws nyuaj rau cov cuab yeej siv los kuaj xyuas lawv kom raug.
Teeb meem kev xav: Lub teeb ntawm lub vijtsam yog rov qab mus rau lub tshuab luam ntawv, ua rau nws nyuaj rau lub tshuab luam ntawv kom paub qhov txawv ntawm thaj tsam thiab cov ntsiab lus ntawm QR code. Qhov no yuav ua rau lub vijtsam code tsis raug lees paub los ntawm lub tshuab luam ntawv.
Teeb meem cuam tshuam: Thaum lub sij hawm tus txheej txheem ntawm kev tshuaj ntsuam ntawm on-screen code, lub teeb yog refracted ntau zaus los ntawm lub scanning ntaus ntawv thiab lub vijtsam, uas tej zaum yuav ua rau scanning ntaus ntawv tsis tau nyeem cov ntaub ntawv ntawm tus QR code kom raug.
2.3. Ib txwm siv 1D CCD barcode scanners ntsib ntau yam teeb meem thaum luam theej duab ntawm lub vijtsam.
Kev sib tw qis qis: Ib txwm siv 1D CCD barcode scanners yuav tsis tuaj yeem nyeem cov lej qis ntawm qhov screen. Txij li thaum cov zaub ntawm cov lej tshuaj ntsuam raug txwv los ntawm qhov ci thiab qhov sib piv ntawm lub vijtsam, lub tshuab luam ntawv yuav tsis tuaj yeem raug ntes thiab txiav txim siab cov ntaub ntawv hauv 2D code.
Reflection thiab refraction challenges: Lub teeb los ntawm on-screen codes yog reflected thiab refracted, ua rau nws nyuaj rau scanners kom raug nyeem QR codes. Ib txwm CCD1D barcode scannersfeem ntau yog tsim los luam theej duab daim ntawv barcodes thiab tej zaum yuav tsis muaj peev xwm daws tau qhov teeb meem ntawm kev xav thiab kev cuam tshuam ntawm cov lej tshuaj ntsuam.
Txhawm rau kov yeej cov teeb meem no, tam sim no muaj cov cuab yeej tshwj xeeb tsim los luam theej duab cov lej, xws li2D scannerslos yog tshwj xeeb screen code scanners. Cov cuab yeej siv thev naus laus zis thev naus laus zis thev naus laus zis txhawm rau txhawm rau ntes tau zoo dua thiab txiav txim siab cov ntaub ntawv ntawm cov lej tshuaj ntsuam.

3.1 Tej yam 1D CCD barcode scanners muaj peev xwm luam theej duab on-screen codes. Cov scanners no tshwj xeeb tsim los txheeb xyuas thiab txiav txim siab 2D code cov ntaub ntawv tso tawm ntawm qhov screen. Lawv tuaj yeem nyeem cov lej tshuaj ntsuam nrog qhov tsis sib xws, kev xav thiab teeb meem refraction los muab cov txiaj ntsig raug.
3.2 Cov qauv khoom thiab kev ua haujlwm tshwj xeeb yog qhov tseem ceeb thaum luam theej duab ntawm lub vijtsam. Vim tias cov lej tshuaj ntsuam muaj cov kev xav tau tshwj xeeb scanning, tsuas yog cov scanners nrog cov cuab yeej tsim nyog thiab cov yam ntxwv tuaj yeem luam theej duab tau zoo. Yog li ntawd, thaum yuav ib tug 1D CCD barcode scanner, xyuas kom meej tias nws muaj peev xwm luam theej duab lub screen code thiab ua tib zoo mloog rau cov khoom uas muaj feem xyuam rau cov qauv thiab kev ua tau zoo, xws li kev soj ntsuam qhov tseeb, kev xav txog kev tsuj thiab refraction kuj.
Hauv digital era, 1D CCDbarcode scannermuaj kev lag luam dav thiab kev cia siab. Nws tuaj yeem siv rau hauv khw muag khoom, kev thauj mus los, kev thauj mus los, daim pib thiab lwm yam kev lag luam los txhim kho kev ua haujlwm zoo thiab muab kev yooj yim rau cov neeg siv khoom. Yog li ntawd, xaiv txoj cai 1D CCD barcode scanner thiab nkag siab txog nws lub peev xwm los luam theej duab ntawm lub vijtsam yog ib kauj ruam tseem ceeb rau kev hloov pauv digital.
Peb cia siab tias qhov kev paub no yuav pab txhua tus neeg siv khoom nkag siab txog cov yam ntxwv ntawm peb cov scanners, xav tias dawb nias rautiv tauj peb cov neeg ua haujlwm muag khoomthiab tau txais ib nqe lus hnub no.
Yog tias koj nyob hauv kev lag luam, koj tuaj yeem nyiam
