Thaum RFID cov cim npe txuas ncaj qha rau ntawm cov chaw hlau, lawv qhov kev nyeem ntawv tuaj yeem ua rau poob qis, lossis lawv yuav tsis lees paub tag nrho. Qhov no tshwm sim vim hlau yog cov conductive heev; Nws cuam tshuam cov nthwv dej electromagnetic thiab hloov pauv cov khoom siv hluav taws xob sib txawv nyob ib ncig ntawm lub cim npe kav hlau txais xov, yog li cuam tshuam rau tus kav hlau txais xov impedance txuam thiab resonant zaus. RauUHF RFID cim npe, cov kev hloov no tuaj yeem ua rau txo cov kav hlau txais xov hluav taws xob, kev nyeem luv luv, thiab tsis ruaj khov nyeem / sau ua haujlwm.
Hlau shelving, steel ntim, machinery, thiab hlau piping yog ib qho chaw nyob rau hauv daim ntawv thov xws li kev lag luam khoom vaj khoom tsev, warehousing thiab logistics, cov cuab yeej mus txog qhovtwg, thiab kev txheeb xyuas lub tsheb. Tus qauv RFID cov cim npe feem ntau ua tsis tiav los muab kev txheeb xyuas txhim khu kev qha thaum txuas ncaj qha rau ntawm cov chaw no. Yog li ntawd, xaiv ib qho RFID tag haum rau cov hlau ib puag ncig yuav tsum muaj kev ntsuam xyuas ntau yam xws li cov qauv kav hlau txais xov, cov khoom siv, thiab cov kev teeb tsa tiag tiag.
Yuav ua li cas los tiv thaiv cov khoom siv hlau txhim kho RFID kev ua tau zoo?
Anti-hlau RFID tags feem ntau yog siv cov khoom sib txuas thiab cov kav hlau txais xov tsim los txo cov kev tsis zoo uas cov hlau nto muaj nyob rau hauv electromagnetic teb thiab kav hlau txais xov ua haujlwm. Cov ntaub ntawv uas muaj xws li ferrites, dielectric cais txheej, ua npuas ncauj cushioning, thiab lwm yam ntaub ntawv uas muaj cov yam ntxwv electromagnetic.
Ferrites tuaj yeem pab qhia cov chaw sib nqus thiab txo qis kev sib txuas ntawm cov kav hlau txais xov thiab cov hlau ntawm cov zaus tshwj xeeb thiab cov qauv tsim;
Dielectric cais txheej tsim qhov sib txawv ntawm lub kav hlau txais xov thiab cov hlau nto, pab tswj cov kav hlau txais xov cov yam ntxwv hluav taws xob.
Kev ua haujlwm ntawm cov ntaub ntawv no nyob ntawm qhov ua haujlwm zaus, kav hlau txais xov geometry, cov khoom thickness, thiab dielectric lossis magnetic permeability zog. Piv txwv li, muaj qhov sib txawv tseem ceeb hauv kev tsim cov kav hlau txais xov thiab xaiv cov khoom siv ntawm13.56 MHz HF RFID cim npethiab UHF RFID cim npe ua haujlwm hauv 860–960 MHz ntau yam. Ib qho tsis tuaj yeem xav tias cov khoom siv tshwj xeeb los tiv thaiv hlau yog tsim nyog rau txhua qhov zaus, thiab tsis tuaj yeem txiav txim siab los ntawm lub npe ntawm cov khoom siv.
Koj xaiv cov khoom siv hlau zoo li cas?
Kev xaiv cov khoom siv los tiv thaiv hlau yuav tsum ua raws li qhov yuav tsum tau ua ntawm daim ntawv thov tshwj xeeb. Cov ntaub ntawv Ferrite feem ntau yog siv hauv NFC cov qauv tsim los txo cov kev cuam tshuam hlau, qhov UHF RFID tags feem ntau xav tau ib qho kev tsim qauv uas xav txog cov qauv kav hlau txais xov, cov khoom siv hluav taws xob, kev sib cais, thiab impedance txuam. Cov ntaub ntawv yuav tsum tsis tsuas yog txhim kho electromagnetic kev ua tau zoo tab sis kuj ua tau raws li cov kev txwv ntawm tag qhov ntev, mounting txoj kev, thiab kev khiav hauj lwm ib puag ncig.
Piv txwv li, ib qho RFID tag mounted rau ntawm cov cuab yeej steel yuav tsum muaj cov tswv yim tsim txawv dua li ib qho txuas rau cov yeeb nkab hlau nkhaus lossis cov khoom siv tsheb. Yog tias daim ntawv thov ib puag ncig muaj qhov kub thiab txias, av noo, lossis kev poob siab, cov khoom xws li cov khoom siv hluav taws xob, cov khoom adhesion, thiab kev ruaj ntseg mus ntev yuav tsum tau txiav txim siab. Hauv cov cuab yeej taug qab qhov xwm txheej uas qhov chaw txwv tsis pub, daim ntawv tuab thiab qhov chaw txuas ntxiv yuav cuam tshuam rau qhov kev xaiv tsim kawg.
Yuav ua li cas qhov tseeb ntawm cov hlau-mount RFID cim npe yuav raug txheeb xyuas?
Nyeem ntau yam ntawm tus qauv nto tsis ncaj qha cuam tshuam txog kev ua tau zoo thaum lub cim tau teeb tsa ntawm cov hlau. Kev ntsuam xyuas yuav tsum siv cov hlau substrate tiag tiag, tus nyeem ntawv RFID tshwj xeeb thiab kav hlau txais xov, thiab tswj cov kev taw qhia mounting, kev khiav hauj lwm zaus, thiab nyeem qhov deb. Rau UHF RFID systems, lwm yam xws li lub zog nyeem ntawv, kav hlau txais xov polarization, ib puag ncig cov qauv hlau, qhov sib nrug, thiab cov kev cai xov tooj cua hauv zos yuav tsum raug coj mus rau hauv tus account.
Thaum ntsuas hlau-mount RFID cim npe, ib tus yuav tsum xav txog tsis tsuas yog nyeem ntau yam tab sis kuj nyeem cov txiaj ntsig tau zoo, kev txheeb xyuas kev ruaj ntseg, ib puag ncig ruaj khov, thiab kev ua haujlwm sib txawv raws li qhov sib txawv mounting. Kev ntsuam xyuas raws li kev ua haujlwm tiag tiag tso cai rau kev soj ntsuam kom raug ntau dua ntawm cov cim npe rau cov ntawv thov xws li kev tswj hwm cov khoom vaj khoom tsev, cov khoom siv kev lag luam nrhiav, lossis kev txheeb xyuas cov thawv hlau.
