Puas RFID ua haujlwm los ntawm hlau? Cov ntaub ntawv teev cov RFID cov tsoos yuav ua tsis tiav lossis sau ntawv, muaj cov phiaj xwm luv luv, lossis muaj phiajcim tsis meej pem ntawm cov hlau. Qhov no yog vim tias cov hlau ua kom pom tseeb lossis nqus cov cim qhia rf, ua rau cov kev ua tau zoo ntawm tus kav hlau txais xov kom swb. Cov nyhuv no yog tshwj xeeb tshaj plaws hauv UHF Band (xws li 902-928mHz).
Vim li cas ib puag ncig hlau cuam tshuam nrog RFID?
Xav rf cim:Hlau qhia txog cov hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob zoo li daim iav, cuam tshuam kev sib txuas lus nruab nrab ntawm daim cim thiab tus nyeem.
Absorbing Zog:Hauv qee kis, hlau tseem nqus RF zog, ua rau pom kev ua haujlwm.
Kav hlau txais xov xwm:Cov hlau nto hloov pauv cov impedance ntawm lub kav hlau txais xov thiab cuam tshuam rau qhov chaw uas muaj resonant ntawm daim pib.
Kev daws:Hlau-Spfid Cim npe
Txhawm rau kov yeej cov teeb meem no, peb lub tuam txhab tau tsim cov cim npe tau tsim tshwj xeeb rau cov hlau ib puag ncig. Cov no muaj cov yam ntxwv hauv qab no:
Cov Khoom Siv Rho Tawm:Ntxiv cov txheej sib cais ntawm cov kav hlau txais xov thiab cov hlau kom tiv thaiv cov cim kev cuam tshuam rau cov cim.
Directional kav hlau txais xov tsim:Ua kom zoo RF txoj kev tsim qauv kom ntseeg tau tias cov cim npe tuaj yeem xa tawm cov cim tawm sab nraud.
Ntim Ntim:Qee cov npe tau ntim nrog cov khoom siv abs, uas yog ruaj thiab haum rau cov chaw hnyav.
