Vim li cas 2D Barcode Scanner tsis tuaj yeem nyeem Barcode thaum nws nyob ze lossis nyob deb?

Peb feem ntau ntsib cov teeb meem zoo li no Vim li cas 2D barcode scanner tsis hnov ​​​​tsw heev rau luam theej duab thaum nws nyob ze rau ntawm barcode lossis deb ntawm barcode, thiab qee zaum nws tsis tuaj yeem luam tawm txhua. Yuav kom nrhiav tau cov lus teb rau lo lus nug no, ua ntej peb yuav tsum to taub qhov muaj pes tsawg leeg ntawm barcode scanner.

Cov qauv ntawm OEM 2D barcode scanner feem ntau yog muab faib ua cov hauv qab no: lub teeb qhov chaw, txais cov cuab yeej, photoelectric hloov dua siab tshiab tivthaiv, kev txiav txim siab Circuit Court, computer interface. Lub hauv paus tseem ceeb ntawm lub tshuab luam ntawv yog cov khoom siv uas ua tiav cov kev hloov pauv photoelectric - cov khoom siv scanning (tseem hu ua cov cuab yeej photosensitive). Cov khoom siv photosensitive tshaj plaws nyob rau hauv kev ua lag luam uas tuaj yeem paub txog ob-dimensional barcodes yog hlau oxide conductor CMOS. Nws muaj cov cuab yeej siv duab zoo dua thiab cov duab ntse ntse paub qhov system. Nws siv daim duab ntawm barcode thiab xa mus rau lub cuab yeej sab hauv rau kev tshuaj xyuas.

Qhov kev ncua deb thiab ze ntawm barcodes scanning muaj xws li ib tug kws tshaj lij, uas yog ua hauj lwm nyob deb. Qhov kev ua haujlwm nyob deb no muaj feem xyuam nrog kev daws teeb meem ntawm lub koob yees duab, uas tuaj yeem nkag siab zoo li cov duab thev naus laus zis ntawm CMOS. Kev nyeem ntawv daws teeb meem ntawm 1D 2D barcode scanner yog ib qho tseem ceeb heev, uas feem ntau txiav txim siab los ntawm peb yam: qhov muag qhov muag, qhov khoom kho vajtse thiab qhov software. Qhov kev daws teeb meem ntawm lub scanner yog sib npaug rau qhov kev daws teeb meem ntawm qhov chaw kho qhov muag ntxiv rau nws tus kheej cov kev daws teeb meem tau los ntawm kev kho vajtse thiab software ua kev tshuaj xyuas. Qhov tseeb daws teeb meem ntawm tus nyeem ntawv yog qhov kev daws teeb meem ntawm CMOS tivthaiv lub koob yees duab. Kev daws teeb meem ncaj qha cuam tshuam rau lub focal ntev ntawm lub koob yees duab, uas yog qhov ua haujlwm nrug ntawm lub scanner. Vim li no, yog tias qhov kev ncua deb ntawm barcode scanner thiab barcode hloov pauv, lub bar dub thiab thaj chaw dawb paug ntawm barcode yuav tsis raug qhov txawv, thiab barcode yuav tsis raug tshuaj xyuas yog tias qhov deb dhau los yog nyob deb dhau.

Ib tug ob-dimensional barcode nyeem ntawv tuaj yeem nkag siab zoo li lub koob yees duab. Yog tias qhov kev ncua deb dhau los yog deb dhau, nws tsis tuaj yeem saib xyuas qhov zoo li qub ntawm cov khoom, uas cuam tshuam rau qhov zoo ntawm cov duab. Ib yam yog qhov tseeb thaum kev yuav khoom, cov nqi pheej yig heev thiab kim heev tsis tas li peb xav tau.Peb xav tau cov khoom tsim nyog rau peb tus kheej cov haujlwm. Peb lub tuam txhab tshwj xeeb hauv kev daws teeb meem scanning, thiab koj tuaj yeem tuaj thiab sab laj.
