Dab tsi yog cov yam ntxwv ntawm RFID Systems?

Nrog rau kev loj hlob tsis tu ncua ntawm RFID thev naus laus zis thiab kev nce ntxiv ntawm cov ntawv hla cheeb tsam thiab hla kev lag luam, qhov zoo ntawm RFID systems tau maj mam raug pov thawj thiab dhau los ua cov ntawv thov nrov. Dab tsi yog cov yam ntxwv ntawm RFID systems?

Nyeem / sau kev ua haujlwm ntawm cov ntaub ntawv tsis sib cuag
RFID tuaj yeem nyeem cov ntaub ntawv ncaj qha rau hauv cov ntaub ntawv hauv lub xeev tsis muaj kev sib cuag, thiab tuaj yeem ua tiav ntau lub cim npe ib zaug. Cov txheej txheem ua tiav tuaj yeem sau rau hauv cov cim npe rau theem tom ntej ntawm kev ua tiav thiab nyeem ntawv txiav txim. Qhov kev nyeem ntawv thiab kev sau ntawv deb ntawm lub cim yog li ntawm ob peb centimeters mus rau ntau kaum ntawm meters, ua rau nws haum rau luv luv wireless kis ntawm cov ntaub ntawv.

Kev ntseeg tau thiab kav ntev
Tsis muaj kev sib cuag ntawm RFID tag thiab tus nyeem ntawv, zam kev nyeem ntawv thiab sau ntawv yuam kev los ntawm kev sib cuag tsis zoo. Txawm nyob rau hauv ib puag ncig hnyav, nws tsis cuam tshuam rau kev nyeem ntawv thiab kev sau ntawv. Tsis tas li ntawd, RFID chips tau ntim rau hauv, yog li tsis tas yuav txhawj xeeb txog nti detachment, electrostatic tawg, dabtsi yog khoov puas, thiab lwm yam, yog li lub neej kev pab cuam kuj ntev.

Ceev thiab yooj yim
RFID tuaj yeem paub thiab nyeem ntau lub cim RFID ib txhij, txhim kho kev ua haujlwm zoo. Vim yog kev siv cov kev sib txuas lus tsis sib txuas, tus nyeem ntawv tuaj yeem ua haujlwm RFID tagged cov cim qhia txog cov khoom nyob rau hauv thaj tsam ntawm ob peb centimeters mus rau kaum ntawm meters, yog li tsis tas yuav tsum tau ua haujlwm ntxig thiab tshem tawm xws li IC phaib. Thaum nyob rau hauv kev siv tsis sib cuag, tsis muaj kev taw qhia, uas tuaj yeem txhim kho kev siv ceev thiab ua tiav kev nyeem ntawv thiab sau cov haujlwm hauv lub sijhawm luv luv.

Cov ntaub ntawv loj muaj peev xwm
Lub peev xwm ntawm ib-seem barcode yog 50B, qhov siab tshaj plaws muaj peev xwm ntawm ob-dimensional barcode tuaj yeem khaws 1108B, thiab lub peev xwm siab tshaj plaws ntawm RFID yog ob peb megabytes. Nrog rau txoj kev loj hlob ntawm cov neeg nqa khoom nco, kuj tseem muaj qhov sib txawv ntawm kev nthuav dav ntawm cov ntaub ntawv muaj peev xwm. Tus nqi ntawm cov ntaub ntawv xav tau rau yav tom ntej cov khoom nqa yuav nce ntxiv, thiab qhov kev thov kom nthuav dav lub peev xwm ntawm cov ntawv tseem yuav nce ntxiv. Muaj ntau qhov sib faib hauv RF, txhua tus muaj nws tus kheej lo lus zais, yog li sib txawv tuaj yeem siv rau kev siv sib txawv kom ua tiav ntau yam.

Anti kev sib tsoo mechanism
RFID cov cim npe muaj lub nrawm tiv thaiv kev sib tsoo uas tuaj yeem tiv thaiv cov ntaub ntawv cuam tshuam ntawm cov cim npe. Yog li ntawd, tus nyeem ntawv tuaj yeem ua ntau yam tsis sib tiv tauj ib txhij, thiab tuaj yeem ua ntau lub cim npe ib txhij.

Kev ruaj ntseg
Vim tias qhov hluav taws xob ntawm cov ntaub ntawv nqa los ntawm RFID, nws cov ntsiab lus ntawm cov ntaub ntawv tuaj yeem tiv thaiv tus password, ua rau nws tsis tshua muaj kev phom sij thiab hloov pauv. Tus naj npawb ntawm RFID cov cim npe muaj qhov tshwj xeeb, thiab cov chaw tsim khoom tau ua kom muaj tus lej xov tooj no ua ntej cov khoom tawm hauv lub Hoobkas thiab tsis tuaj yeem hloov nws dua. Tus nyeem ntawv tuaj yeem txheeb xyuas qhov tseeb ntawm daim ntawv, thiab daim ntawv tseem tuaj yeem txheeb xyuas qhov tseeb ntawm tus nyeem ntawv. Ua ntej ua tiav, daim npav yuav tsum tau lees paub nrog tus nyeem ntawv, thiab tag nrho cov ntaub ntawv raug encrypted thaum lub sijhawm sib txuas lus. Tsis tas li ntawd, txhua feem ntawm RFID tag muaj nws tus password ua haujlwm thiab nkag mus rau cov xwm txheej.

Qhov loj me thiab ntau hom duab sib txawv
RFID cov cim npe tsis txwv los ntawm qhov loj lossis cov duab hauv kev nyeem ntawv, thiab tsis tas yuav tsum tau ua kom haum nrog cov ntawv loj thiab luam ntawv zoo rau kev nyeem ntawv raug. Tsis tas li ntawd, RFID cim npe tuaj yeem tsim kho rau hauv cov ntawv me me thiab ntau hom ntawv siv rau cov khoom sib txawv.

Nkag mus thiab thaiv kev nyeem ntawv dawb
Thaum npog, RFID cim npe tuaj yeem nkag mus rau cov khoom tsis yog xim hlau lossis cov ntaub ntawv tsis muaj pob tshab xws li ntawv, ntoo, thiab yas los pauv cov ntaub ntawv nrog cov neeg nyeem thiab cov neeg sau ntawv. Tsuas yog cov hlau hlau, vim nws cov nyhuv shielding, cuam tshuam kev nthuav tawm ntawm electromagnetic tsis thiab tiv thaiv kev sib txuas lus ib txwm. Yog li ntawd, RFID anti hlau cim yuav tsum tau ua kom tiav cov ntaub ntawv sib pauv hauv cov hlau ib puag ncig.

Flow xyuas thiab positioning
RFID cov cim npe tuaj yeem txuas rau cov khoom siv kom pom thiab muab tso rau. Los ntawm cov khoom siv raw khoom, kev tsim khoom mus rau cov khoom muag, tag nrho cov ntaub ntawv hais txog cov khoom tuaj yeem raug kaw siv RFID cim npe. Nyob rau hauv cov ntaub ntawv ntawm kev huam yuaj, lub hauv paus ntawm qhov teeb meem yuav sai sai thiab meej tracing, ua tiav cov khoom zoo mus txog qhovtwg.
