Passive, Active, lossis Semi-Active: Phau Ntawv Qhia rau RFID Label Power Options
Taug kev los ntawm lub tsev khaws khoom thiab koj yuav pom cov thawv, pallets, thiab cov khoom txav mus rau txhua qhov chaw. Ib txhia nqaRFID daim ntawv louas raug nqi ob peb xees. Lwm tus nqa cov cim npe uas raug nqi ntau dua li cov khoom hauv. Qhov sib txawv feem ntau los rau ib yam: yuav ua li cas lub cim tau txais nws lub hwj chim.
RFID daim ntawv lo tuaj nyob rau hauv peb lub zog loj: passive, nquag, thiab semi-active (tseem hu ua semi-passive lossis roj teeb-pab passive). Txhua yam ua haujlwm sib txawv, tus nqi sib txawv, thiab haum rau cov haujlwm sib txawv. Xaiv qhov tsis ncaj ncees lawm tuaj yeem txhais tau tias tus nqi nyeem tsis zoo, siv nyiaj siv tsis raug, lossis lub kaw lus tsis ua haujlwm.
Phau ntawv qhia no rhuav tshem peb txoj kev xaiv fais fab kom koj tuaj yeem xaiv daim ntawv RFID txoj cai rau koj cov kev xav tau.
Passive RFID Labels: Tsis muaj roj teeb, tsis muaj kev tu
Lawv ua haujlwm li cas
Daim ntawv lo passive RFID tsis muaj roj teeb. Nws tos rau lub teeb liab los ntawm RFID nyeem ntawv. Tus nyeem ntawv xa xov tooj cua tsis muaj zog, thiab lub cim npe kav hlau txais xov ntes lub zog ntawd. Lub zog muaj zog rau tag lub microchip ntev txaus rau nws xa rov qab nws cov ntaub ntawv khaws cia. Qhov teeb liab rov qab no yog hu ua "backscatter".
Xav txog nws zoo li daim iav uas pom lub teeb. Lub cim tsis tsim nws tus kheej lub teeb liab. Nws tsuas cuam tshuam thiab hloov pauv yam uas tus nyeem xa tuaj.
Nyeem Range thiab Performance
Passive UHF tags feem ntau ncav cuag 1 txog 15 meters, nyob ntawm seb lub zog nyeem ntawv, kav hlau txais xov loj, thiab ib puag ncig. Passive HF thiab NFC tags ncav cuag luv dua - los ntawm ob peb centimeters mus txog 1 meter.
Nqi thiab Lifespan
Passive RFID daim ntawv lo yog qhov kev xaiv pheej yig tshaj. Siab -Volume passive UHF inlays tam sim no raug nqi qis dua $0.04 ib tag, poob ntau dua 75% piv rau ob peb xyoos dhau los. Daim ntawv-raws li cov ntawv sau tau $0.04 txog $0.08 txhua. Vim tias tsis muaj roj teeb kom ntws, cov ntawv cim passive yuav nyob tsis muaj hnub kawg.
Zoo tshaj rau
Cov ntawv cim Passive yog qhov zoo tagnrho rau cov khw muag khoom muag, cov khoom lag luam taug qab, cov phau ntawv hauv tsev qiv ntawv, thiab txhua daim ntawv thov uas koj xav tau sau ntau txhiab tus nqi qis - cov khoom raug nqi. Lawv kuj yog qhov yooj yim tshaj plaws los luam tawm hauv - tsev siv cov tshuab luam ntawv RFID txheem.
Active RFID Labels: Roj teeb -Powered Beacons
Lawv ua haujlwm li cas
Lub active RFID tag muaj nws lub roj teeb. Nws tsis tos tus nyeem ntawv los txhawb nws. Hloov chaw, nws tshaj tawm nws tus kheej lub teeb liab ntawm lub sijhawm tsis tu ncua - zoo li lub teeb hluav taws xob xa tawm lub teeb.
Vim tias lub cim tsim nws tus kheej lub teeb liab, nws tuaj yeem kis tau ntau dua li lub cim passive. Cov cim npe nquag ncav cuag 30 txog 100 meters hauv tsev thiab mus txog 300 meters sab nraum zoov hauv qhib- huab cua.
Nyeem Range thiab Performance
Cov cim npe nquag yog qhov ntev - kis tau tus mob. Lawv tuaj yeem nyeem tau yooj yim txawm tias nyob rau hauv ib puag ncig nyuaj nrog hlau, kua, lossis teeb meem uas yuav thaiv cov cim tsis zoo.
Nqi thiab Lifespan
Active tags raug nqi $15 txog $100 lossis ntau dua rau ib tag. Lawv muaj roj teeb lub neej ntawm 2 mus rau 7 xyoo, nyob ntawm seb lawv kis tau ntau npaum li cas thiab seb lawv suav nrog cov sensors. Thaum lub roj teeb tuag, lub cim npe feem ntau yog hloov es tsis kho.
Zoo tshaj rau
Cov cim npe nquag ua rau muaj txiaj ntsig zoo rau kev taug qab siab - cov khoom muaj nqis tshaj qhov deb - cov thawv xa khoom, tsheb, tsheb thauj khoom, lossis cov khoom siv loj. Lawv kuj tau siv hauv qhov tiag -lub sijhawm qhov chaw nyob (RTLS) qhov chaw uas koj yuav tsum paub qhov twg ib yam dab tsi nyob rau txhua lub sijhawm, tsis yog thaum nws hla qhov chaw kuaj xyuas xwb.
Semi-Khwv RFID Labels: Lub Hauv Paus Nruab Nrab
Lawv ua haujlwm li cas
Semi-active tag (tseem hu ua semi-passive lossis roj teeb-pab passive) muaj lub roj teeb me me, tab sis nws ua haujlwm txawv ntawm lub cim ua haujlwm. Lub roj teeb powers tag lub microchip thiab ib qho onboard sensors, tab sis nws tsis xa cov teeb liab. Hloov chaw, daim ntawv sib txuas lus siv tib txoj kev backscatter raws li daim ntawv passive.
Hauv cov ntsiab lus yooj yim: lub roj teeb tsa lub nti, tab sis tus nyeem ntawv tseem ua qhov hnyav nqa rau kev sib txuas lus.
Nyeem Range thiab Performance
Vim tias lub roj teeb muaj zog rau lub nti, lub cim npe tuaj yeem siv tag nrho lub zog uas nws ntes los ntawm tus nyeem ntawv los cuam tshuam cov teeb liab rov qab. Qhov no muab ib nrab - cov cim ua haujlwm tau nyeem ntev dua li cov cim passive - feem ntau 15 txog 30 meters.
Nqi thiab Lifespan
Semi- cov cim npe ua haujlwm nyob nruab nrab ntawm tus nqi qis thiab ua haujlwm ntawm tus nqi, feem ntau yog $ 5 txog $ 25 rau ib tag. Lub roj teeb lub neej nyob ib ncig ntawm 5 xyoos, thiab tom qab lub roj teeb tuag, lub cim tseem tuaj yeem ua haujlwm raws li daim npav passive.
Zoo tshaj rau
Semi-cov cim npe nquag muaj txiaj ntsig zoo rau cov ntawv thov uas xav tau nruab nrab- ntau yam nyeem ntxiv rau cov ntaub ntawv sensor. Cov kev siv feem ntau suav nrog kev saib xyuas cov hlua txias (kub thiab av noo), kev taug qab cov cuab yeej cuab tam hauv cov tsev khaws khoom, thiab kev tshuaj xyuas cov khoom siv uas koj yuav tsum tau nkag mus rau lub sijhawm.

Yuav Ua Li Cas Xaiv Txoj Kev Xaiv Fais Fab
Kauj Ruam 1: Pib nrog Koj Qhov Ncauj Nyeem Ntawv
Yuav tsum nyeem tag deb npaum li cas? Yog tias ob peb meters txaus, passive yog cov lus teb. Yog tias koj xav tau 20 meters, saib ib nrab- nquag. Yog tias koj xav tau 50 meters lossis ntau dua, mus ua haujlwm.
Kauj ruam 2: Xav txog koj lub ntim
Passive tags ua rau kev nkag siab thaum koj sau npe ntau txhiab yam khoom. Cov cim npe nquag ua rau muaj kev nkag siab zoo thaum koj tab tom taug qab kaum ob lub siab - cov khoom muaj nqis. Tus nqi ib tag hloov pauv kev lag luam nkaus xwb.
Kauj Ruam 3: Txiav txim siab yog tias koj xav tau Sensors
Yog tias koj xav tau saib xyuas qhov kub thiab txias, av noo, lossis poob siab thaum thauj khoom, ib nrab - cov cim npe ua haujlwm lossis cov cim ua haujlwm nrog onboard sensors yog txoj hauv kev mus. Passive tags tuaj yeem txhawb nqa cov haujlwm tsis muaj zog, tab sis lawv xav tau tus nyeem ntawv muaj zog thiab nyob ze.
Kauj Ruam 4: Tshawb xyuas Koj Lub Peev Xwm Muaj Peev Xwm
Passive tags xav tau xoom txij nkawm - tsis muaj roj teeb los hloov. Active thiab semi-{2}} cov cim npe nquag muaj cov roj teeb lub neej ntev thiab yuav xav tau hloov pauv txhua ob peb xyoos. Ua rau koj tus nqi tag nrho.
FAQ
Q1: Dab tsi yog qhov txawv ntawm passive, nquag, thiab semi- nquag RFID daim ntawv lo?
A: Cov ntawv cim Passive tsis muaj roj teeb thiab tau txais tag nrho lawv lub zog los ntawm tus nyeem ntawv. Cov cim npe nquag muaj lub roj teeb thiab tshaj tawm lawv cov teeb liab. Semi- cov cim npe nquag muaj lub roj teeb uas ua rau lub zog nti, tab sis lawv tseem siv backscatter los sib txuas lus.
Q2: Ntev npaum li cas txhua hom tuaj yeem nyeem tau?
A: Passive UHF tags ncav cuag 1-15 meters. Semi- cov cim ua haujlwm ncav cuag 15–30 meters. Cov cim npe nquag ncav cuag 30-100 meters hauv tsev thiab mus txog 300 meters sab nraum zoov.
Q3: Hom twg yog qhov pheej yig tshaj?
A: Cov ntawv cim Passive yog nyob deb ntawm qhov pheej yig tshaj plaws, raug nqi qis dua $ 0.04 rau ib daim ntawv loj. Semi- cov cim npe nquag raug nqi $ 5– $ 25, thiab cov cim npe nquag pib nyob ib puag ncig $ 15 thiab nce mus txog $ 100 lossis ntau dua.
Q4: Puas yog ib nrab- cov cim npe tsis ua haujlwm thaum lub roj teeb tuag?
A: Tsis yog. Tom qab lub roj teeb tuag, ib nrab - cov cim npe tseem tuaj yeem ua haujlwm raws li cov cim tsis raug. Koj poob qhov txuas ntxiv thiab lub peev xwm sensor, tab sis kev txheeb xyuas qhov tseem ceeb tseem ua haujlwm.
Q5: Yam twg kuv yuav tsum siv rau kev saib xyuas cov hlua txias?
A: Semi- cov cim npe nquag feem ntau yog qhov zoo tshaj plaws. Lawv muab qhov nruab nrab - ntau yam nyeem ntxiv rau onboard kub thiab av noo sensors, ntawm tus nqi qis dua tag nrho cov cim npe.
