OEM Barcode Scanner

OEM barcode scanners, tseem hu ua barcode scanners / nyeem ntawv, yog cov cuab yeej siv los nyeem cov ntaub ntawv muaj nyob hauv barcodes, thiab tuaj yeem muab faib ua ib-seem thiab ob-dimensional barcode scanners. Cov qauv ntawm barcode scanner feem ntau yog cov nram qab no: lub teeb qhov chaw, txais cov cuab yeej, photoelectric hloov dua siab tshiab tivthaiv, txiav txim siab Circuit Court, computer interface. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm rab phom scanning yog: lub teeb emitted los ntawm lub teeb qhov chaw yog irradiated ntawm barcode cim los ntawm lub optical system. Lub teeb pom kev zoo yog duab ntawm lub photoelectric converter los ntawm qhov kho qhov muag, thiab txhais los ntawm lub tshuab txiav tawm raws li lub teeb liab digital uas tuaj yeem txais ncaj qha los ntawm lub computer. Ntxiv nrog rau kev faib tawm ntawm ib thiab ob-seem barcode scanners, nws tseem tuaj yeem muab faib ua: CCD, tag nrho lub kaum sab xis laser thiab laser handheld barcode scanners.
Thaum siv lub scanner, tus neeg teb xov tooj yuav tsum kov lub teeb cwj mem mus rau saum npoo ntawm bar code, thiab lub teeb me me tau tawm los ntawm lub lens ntawm lub teeb cwj mem. Nyob rau hauv ib feem ntawm "stripe", lub teeb yuav absorbed, yog li ib tug hloov voltage yuav generated nyob rau hauv lub teeb cwj mem, thiab qhov voltage no yuav siv rau decoding tom qab amplification thiab shaping.
