Barcode scanning modules (xws li ob qho tib si 1D thiab 2D versions), tseem hu ua barcode nyeem ntawv, yog cov khoom tseem ceeb rau kev txheeb xyuas qhov barcode tsis siv neeg. Lawv ua haujlwm tseem ceeb rau kev txhim kho theem nrab ntawm cov khoom siv ntse xws li PDAs, barcode scanner modules, tus kheej -kev pabcuam kiosks, thiab nkag mus tswj rooj vag. Cov modules no muaj peev xwm ua tiav, kev soj ntsuam ywj pheej thiab kev txiav txim siab thiab tso cai rau kev ua haujlwm ntawm kev lag luam- tshwj xeeb ua haujlwm raws li xav tau.
Lawv tuaj yeem raug cais los ntawm lawv lub teeb ci rau hauv laser scanning modules thiab liab -lub teeb scanning modules; cia peb tshuaj xyuas lawv qhov sib txawv tshwj xeeb hauv kev nthuav dav.
Laser scanning modules ua haujlwm los ntawm qhov projecting lub laser taw tes los ntawm ib qho chaw sab hauv mus rau ib qho kev cuam tshuam nrog lub tshuab ua haujlwm. Lub vibrating lub cev muaj zog ces oscillates cov khoom no los cheb lub laser taw tes rau hauv ib kab hla barcode, tom qab ntawd lub teeb liab tau txiav txim siab rau hauv cov ntaub ntawv digital ntawm A-D converter. Hauv qhov sib piv, liab- lub teeb scanning modules feem ntau siv lub teeb ci LED thiab lub CCD photosensitive, hloov lub teeb rau hauv hluav taws xob teeb liab.
Laser scanning modules vam khom rau cov nplaum kom ruaj ntseg lawv cov khoom siv kho tshuab sab hauv, ua rau lawv muaj kev puas tsuaj -xws li oscillation vane detaching- thaum vibration. Yog li ntawd, lub laser scanner poob rau hauv av tej zaum yuav tom qab project tsuas yog ib tug dot es tsis txhob ntawm ib txoj kab, ua rau cov nqi kho siab. Liab- lub teeb scanning modules, txawm li cas los xij, tsis muaj cov qauv siv tshuab sab hauv; lawv muab cov kev poob qis dua thiab kev ruaj ntseg, ua rau kho tus nqi qis dua li cov laser modules.
Vim muaj tej yam xws li cov nqi siab dua thiab tsis muaj zog, ntau daim ntawv thov kos npe- suav nrog cov xov tooj ntawm tes, cov khoom siv sib dhos, cov khoom siv kho mob, tus kheej - cov chaw pabcuam, cov rooj sib tham nkag, thiab cov khoom siv tes tuav-tam sim no feem ntau siv liab - teeb 1D lossis 2D scanning modules. Raws li kev lag luam sib txawv xav tau ntau hom scanning modules, nws yog ib qho tseem ceeb uas yuav tau xaiv cov qauv zoo raws li koj qhov chaw ua haujlwm tshwj xeeb. Yog tias koj tsis paub meej tias yuav pib qhov twg, Barcode World nyob ntawm no los pab koj nrhiav kev daws teeb meem zoo tshaj plaws rau koj cov kev xav tau.
