RFID Cim npe: Pawg, zaus, thiab daim ntawv thov
RFID xa cov ntaub ntawv mus rau tus nyeem ntawv los ntawm ntau zaus ntawm electromagnetic teb.
RFID cov cim npe yog categorized raws li qhov zaus uas lawv tau tsim los ua haujlwm. Muaj peb qhov loj ntau zaus uas RFID cim npe ua haujlwm.
Tsawg-Frequency (LF) Tags
High-Frequency (HF) Tags
Ultra-High Frequency (UHF) Tags - passive thiab nquag
1. Tsawg-Frequency Tags (LF)
Thawj zaus ntawm 125kHz - 134kHz
Nyeem tau ib ntu ntawm ob peb ntiv tes
Cov ntaub ntawv xa mus qis tshaj plaws ntawm txhua qhov RFID zaus
Khaws cov ntaub ntawv me me
LF Daim Ntawv Thov - Kev Taug Kev Tsiaj Tsiaj, Kev Tswj Xyuas, Lub Tsheb Ntsiab-Fob, Kev Tshawb Fawb Txog Khoom, thiab Kev Kho Mob
2. High-Frequency Tags (HF) - Feem ntau siv thoob ntiaj teb
Thawj zaus ntawm 13.56MHz
Nyeem ntau: 30 cm
Lub peev xwm ntawm kev nyeem ntau daim ntawv ib txhij
Nws tuaj yeem khaws txog 4k cov ntaub ntawv
Yooj yim nyeem thaum txuas rau cov khoom uas muaj dej, ntaub so ntswg, hlau, ntoo, thiab dej.
HF Daim Ntawv Thov - Cov Phau Ntawv Qiv Ntawv, Daim Npav Tus Kheej Tus Kheej, Lub Hnab Dav Hlau, thiab Daim npav rho nyiaj
3. Ultra-High Frequency Tags (UHF)
Muaj ob hom cim npe uas siv ntau zaus hauv UHF RFID.
UHF Passive Tags - siv lub zog los ntawm RFID nyeem ntawv
Thawj zaus: 860MHz – 960MHz
Nyeem Ntau: 25 meters
High data kis tus nqi
Ntau yam ntawm tag loj
UHF Passive Tag Daim Ntawv Thov - Kev Tshawb Fawb Kev Tshawb Fawb, Kev Tsim Khoom, Tshuaj thiab Hluav Taws Xob Tolling
UHF Active Tags - roj teeb ua haujlwm
Thawj zaus: 433MHz
Nyeem Ntau: 30 - 100+ meters
Lub peev xwm loj
Cov ntaub ntawv hloov pauv siab
UHF Active Tag Daim Ntawv Thov - Kev Tshawb Fawb Tsheb, Kev Tsim Kho Tsheb, thiab Kev Tsim Kho
