Tshawb nrhiav seb lub tshuab luam ntawv barcode twg yog qhov zoo rau koj qhov kev lag luam tshwj xeeb, ib puag ncig thiab kev xav tau.Tau txais lub peev xwm los kov yeej txhua qhov teeb meem nrog cov scanners tsim los luam tawm txhua yam, nyob qhov twg - tsis muaj teeb meem dab tsi.

1, Liab Scanning Phom thiab Laser Scanner

Lub teeb liab scanning phom txais cov teeb pom kev zoo LED, uas tso siab rau CCD lossis CMOS cov ntsiab lus photosensitive thiab tom qab ntawd hloov cov duab hluav taws xob.Lub laser scanning phom illuminates ib qho chaw laser los ntawm lub tshuab laser sab hauv, thiab qhov chaw laser yog tig mus rau hauv lub teeb ntawm lub teeb laser ntawm lub bar code los ntawm lub viav vias ntawm lub vibration motor, uas yog tom qab txiav txim siab rau hauv cov teeb liab digital los ntawm AD.Vim hais tias lub laser cia siab rau lub vibration lub cev muaj zog los ua ib txoj kab laser, nws yooj yim dua puas nyob rau hauv cov txheej txheem ntawm kev siv, thiab nws cov anti-lub caij nplooj zeeg kev ua tau zoo feem ntau tsis zoo li lub teeb liab, thiab nws cov kev paub ceev tsis ceev li. raws li lub teeb liab.

2, Qhov sib txawv ntawm 1D Scanner thiab 2D Scanner

1D barcode scanner tsuas yog luam theej duab 1D barcodes, tab sis tsis yog 2D barcodes;2d barcode scanner tuaj yeem luam theej duab ob qho tib si ib-seem thiab ob-seem barcodes.Ob-dimensional scanning phom feem ntau kim dua ib-seem phom scanning.Hauv qee lub sijhawm tshwj xeeb, tsis yog txhua rab phom scanning ob sab yog tsim nyog, xws li luam theej duab ob-seem code ntawm lub vijtsam ntawm lub xov tooj ntawm tes lossis kos rau ntawm cov hlau.

Cov neeg nyeem ntawv barcode yog ntsaws thiab ua si nrog kev lag luam-kev luam theej duab ua haujlwm, ua rau txawm tias qhov nyuaj tshaj plaws-rau-nyeem barcodes zoo.Txawm hais tias koj lub lag luam xav tau dab tsi, peb muaj lub tshuab scanner los pab. tiv tauj peb rau cov kev daws teeb meem zoo barcode scanner.
