Muaj ob chav kawm ntawm barcodes: ib-dimensional (1D lossis linear) thiab ob-dimensional (2D).Lawv yog siv nyob rau hauv ntau hom kev siv, thiab nyob rau hauv tej rooj plaub yog scanned siv ntau hom tshuab.CovQhov sib txawv ntawm 1D thiab 2D barcode scanning yog nyob ntawm qhov layout thiabtus nqi ntawm cov ntaub ntawv uas tuaj yeem khaws cia hauv txhua qhov, tab sis ob qho tib si tuaj yeem siv tauua tau zoo nyob rau hauv ntau yam kev siv kev txheeb xyuas tsis siv neeg.
1D Barcode Scanning:
Linear los yog1D barcodes, zoo li UPC code feem ntau pom ntawm cov neeg siv khoomcov khoom, siv cov kab sib txawv-dav sib txawv thiab qhov chaw rau encode cov ntaub ntawv -Dab tsi uas tib neeg feem ntau xav txog thaum lawv hnov "barcode."Tawmbarcodes tuav ob peb lub kaum ob cim, thiab feem ntau tau txais lub cevntev npaum li cov ntaub ntawv ntxiv.Vim li no, cov neeg siv feem ntau txwv lawvbarcodes rau 8-15 cim.
Barcode scanners nyeem 1D barcodes kab rov tav.1D laser barcodecov tshuab luam ntawvyog cov feem ntau siv scanners, thiab feem ntau tuaj nyob rau hauv ib" phom" qauv.Cov scanners no tsis tas yuav tsum nyob rau hauv kev sib cuag ncaj qha nrog 1D barcode ua haujlwm kom zoo, tab sis feem ntau yuav tsum nyob hauv thaj tsam ntawm 4.mus rau 24 ntiv tes scan.
1D barcodes yog nyob ntawm cov ntaub ntawv sib txuas kom muaj txiaj ntsig.Yog tias koj luam theej duab UPC code, piv txwv li, cov cim hauv barcode yuav tsumcuam tshuam rau ib yam khoom hauv tus nqi database kom muaj txiaj ntsig.Cov tshuab barcode noyog qhov tsim nyog rau cov khw muag khoom loj, thiab tuaj yeem pab txhim kho cov khoom kom raugthiab txuag lub sijhawm.
2D Barcode Scanning:
2D barcodes, zoo li Cov Ntaub Ntawv Matrix, QR Code lossis PDF417, siv cov qauv ntawm squares, hexagons, dots, thiab lwm yam duab los encode cov ntaub ntawv.Vim lawvqauv, 2D barcodes tuaj yeem tuav cov ntaub ntawv ntau dua 1D cov lej (txog 2000cov cim), thaum tseem tshwm sim lub cev me.Cov ntaub ntawv yog encodedraws li ob qho tib si ntsug thiab kab rov tav txheej txheem ntawm tus qauv,yog li nws tau nyeem hauv ob qhov loj me.
Ib tug 2D barcode scanner tsis yog encode alphanumeric cov ntaub ntawv.Cov lej no tuaj yeem muaj cov duab, chaw nyob hauv lub vev xaib, lub suab, thiab lwm yamhom binary cov ntaub ntawv.Qhov ntawd txhais tau tias koj tuaj yeem siv cov ntaub ntawvseb koj puas txuas nrog lub database lossis tsis.Ib tug loj npaum li cas ntawmcov ntaub ntawv tuaj yeem mus nrog ib yam khoom uas sau nrog a2D barcode scanner.
2D barcode scanners feem ntau yog siv los nyeem 2D barcodes, txawm hais tiasqee qhov 2D barcodes, zoo li cov QR code uas nquag pom, tuaj yeem nyeem taunrog qee lub smartphone apps.2D barcode scanners tuaj yeem nyeem los ntawm ntau dua 3ko taw deb thiab muaj nyob rau hauv cov "phom" style, nrog rau cordless, countertop, thiab mounted styles.Ib txhia2D barcode scannerskuj yogtau tshaj 1D barcodes, muab cov neeg siv yooj yim npaum li cas lawvsiv.
Daim ntawv thov rau 1D thiab 2D Barcode Technology:
1D barcodes tuaj yeem luam theej duab nrog cov tshuab laser ib txwm siv, lossis sivlub koob yees duab-based imaging scanners.2D barcodesNtawm qhov tod tes, tsuas yog nyeem tau siv cov duab.
Ntxiv rau kev tuav cov ntaub ntawv ntau ntxiv, 2D bar codes tuaj yeem ua me me,uas ua rau lawv muaj txiaj ntsig zoo rau kev kos cov khoom uas yuav tsis yogimpractical rau 1D daim ntawv lo barcode.Nrog rau laser etching thiab lwm yam cim cim technologies, 2D barcodes tau siv los taug qab txhua yam.los ntawm cov khoom siv hluav taws xob zoo tshaj plaws rau cov khoom siv phais.
1D barcodes, ntawm qhov tod tes, zoo haum rau kev txheeb xyuas cov khoom uas yuav cuam tshuam nrog lwm cov ntaub ntawv uas hloov ntau zaus.Rautxuas ntxiv nrog UPC piv txwv, cov khoom uas UPC txheeb xyuas yuav tsishloov, txawm tias tus nqi ntawm cov khoom ntawd nquag ua;Yog vim li cas thiaj li txuas cov ntaub ntawv zoo li qub (tus naj npawb ntawm cov khoom) rau cov ntaub ntawv dynamic (tus nqi database) yog qhov kev xaiv zoo dua li encoding nqe lus hauv barcode nws tus kheej.
2D barcodes tau siv ntau dua hauv cov saw hlau thiabkev tsim cov ntawv thov raws li tus nqi ntawm cov duab scanners tau poob.Los ntawmhloov mus rau 2D bar codes, tuam txhab uas muag tuaj yeem encode ntau cov ntaub ntawv khoomthaum ua kom nws yooj yim dua los luam cov khoom thaum lawv txav ntawm cov kab sib dhos lossisconveyors - thiab nws tuaj yeem ua tiav yam tsis muaj kev txhawj xeeb txog scannerkev sib tw.
Qhov no muaj tseeb tshwj xeeb hauv cov khoom siv hluav taws xob, tshuaj, thiab kev kho mobcov khoom lag luam uas cov tuam txhab tau ua haujlwm rau kev muabib qho loj ntawm cov khoom taug qab cov ntaub ntawv ntawm qee yam khoom me me.Piv txwv li, USFDA's UDI cov cai yuav tsum muaj ob peb daimcov ntaub ntawv tsim khoom kom suav nrog qee yam kev kho mobkhoom siv.Cov ntaub ntawv ntawd tuaj yeem nkag tau yooj yim ntawm 2D barcodes me me.
Thaum muaj qhov sib txawv ntawm1D thiab 2D barcode scanning, ob leeghom muaj txiaj ntsig zoo, tus nqi qis ntawm cov ntaub ntawv encoding thiab taug qab cov khoom.Hom barcode (los yog ua ke ntawm barcodes) koj xaiv yuav nyob ntawmntawm cov kev cai tshwj xeeb ntawm koj daim ntawv thov, suav nrog hom thiabtus nqi ntawm cov ntaub ntawv koj xav tau encode, qhov loj ntawm cov khoom vaj khoom tsev / cov khoom, thiab yuav ua li casthiab qhov twg tus lej yuav raug luam tawm.
Yog tias koj muaj kev txaus siab lossis lus nug thaum xaiv lossis siv ib qho bar code scanner, txais tostiv tauj peb! MINJCODEtau cog lus rau kev tshawb fawb thiab kev txhim kho ntawm bar codetshuab luam ntawvtechnology thiab kev siv cov cuab yeej siv,peb lub tuam txhab muaj 14 xyoo ntawm kev lag luam kev lag luam hauv kev lag luam, thiab tau txais kev lees paub los ntawm feem coob ntawm cov neeg siv khoom!
