Handheld terminals kuj tau dhau los ua cov cuab yeej tseem ceeb hauv kev xa khoom, chaw khaws khoom, khw muag khoom, thiab lwm yam. RFID thev naus laus zis tuaj yeem muab faib ua ultra-ntau zaus, siab zaus, thiab qis zaus raws li nws cov zaus ua haujlwm. Ob qhov siab zaus thiab tsawg zaus siv electromagnetic coupling hauv paus ntsiab lus. Yog li, dab tsi yog qhov txawv ntawm high zaus RFID thiab tsawg zaus RFID?
Cov yam ntxwv ntawm High Frequency RFID
Kev ua haujlwm ntau ntawm -frequency RFID yog 3MHz ~ 30MHz, thiab cov ntawv thov zaus hauv kev siv yog 13.56MHz; Lub siab - zaus RFID daim npav nyeem ntawv hloov pauv qhov amplitude ntawm tus kav hlau txais xov hluav taws xob siv lub chaw taws teeb nyeem ntawv los ntawm kev ua rau qhov hluav taws xob ntawm tus nyeem ntawv kav hlau txais xov hloov pauv los ntawm kev sib txuas thiab kev cuam tshuam ntawm cov khoom thauj khoom ntawm daim npav nyeem ntawv. High zaus feem ntau muaj ob tus qauv: ISO14443 thiab ISO15693. ISO1443 feem ntau yog siv rau pej xeem lub hom phiaj, thaum cov cim hluav taws xob raws li ISO15693 feem ntau yog siv hauv kev tswj hwm tsev qiv ntawv thiab kev siv lag luam. Nws cov yam ntxwv muaj xws li cov ntaub ntawv ceev ceev, muaj peev xwm nyeem ntau lub cim hluav taws xob ib txhij, thiab muaj peev xwm txheeb xyuas txhua yam khoom (tshwj tsis yog hlau) los ntawm kev nkag mus, tab sis qhov kev ncua deb yuav txo.
Cov yam ntxwv ntawm Tsawg zaus RFID
Tsawg zaus feem ntau ua haujlwm los ntawm kev sib txuas inductive, nrog kev ua haujlwm zaus ntawm 30kHz txog 300kHz, feem ntau ua haujlwm zaus ntawm 125KHz thiab 134.2KHz, thiab lub wavelength ntawm kwv yees li 2500m. Cov cim tsis tshua muaj feem ntau yog cov cim tsis sib xws, thiab lawv txoj haujlwm ua haujlwm feem ntau yog ua raws li electromagnetic coupling. Lawv cov yam ntxwv yog tias lawv tuaj yeem nkag mus rau txhua yam khoom (tshwj tsis yog cov hlau) rau kev txheeb xyuas, muaj qhov nrug ruaj khov, kev txwv tsis pub muaj kev cuam tshuam, thiab tsuas yog nyeem ib qho ntawm ib lub sijhawm.
High zaus RFID handheld terminals feem ntau siv zaus ntawm 13.56MHz, uas muaj cov yam ntxwv ntawm kev nyeem ntawv ceev thiab sau nrawm thiab kev sib kis ntev. Lawv feem ntau yog siv rau hauv logistics, warehousing, ntau lawm kab automation thiab lwm yam teb, uas muaj peev xwm ua tau siab - ceev nyeem ntawv thiab taug qab cov ntaub ntawv dynamic ntawm cov khoom, txhim kho kev ua hauj lwm efficiency.
Nyob rau hauv sib piv, tsawg- zaus RFID handheld terminals siv zaus ntawm 125kHz lossis 134.2kHz, uas muaj cov yam ntxwv ntawm tus nqi qis, luv kis nrug, thiab rhiab heev rau cov hlau thiab kua. Lawv feem ntau siv rau hauv thaj chaw xws li kev tswj xyuas kev nkag mus, kev tswj tsheb, kev suav cov khoom muag, thiab lwm yam. Lawv tuaj yeem ua tiav ntau yam kev nyeem ntawv, sau ntawv, thiab taug qab, thiab muaj zog tiv taus cov hlau thiab dej, ua rau lawv tsis tshua muaj kev cuam tshuam.
Hauv cov ntsiab lus, muaj qee qhov sib txawv ntawm qhov siab - zaus thiab qis - zaus RFID cov khoom siv tes ua haujlwm nyob rau hauv cov nqe lus ntawm kev ua tau zoo thiab daim ntawv thov, kev tsim kho vajtse thiab kev ua haujlwm, thiab daim ntawv thov scenarios. Thaum xaiv siv RFID handheld terminals, nws yog ib qho tsim nyog los xaiv qhov tsim nyog siab - zaus lossis qis- cov khoom siv zaus raws li qhov xav tau tiag tiag thiab cov xwm txheej ntawm daim ntawv thov, txhawm rau ua kom tau txais txiaj ntsig zoo dua, raug, thiab ntse tswj thiab siv.
