Qhov Tsis Paub ntawm RFID Tag Nqis: Yuav Ua Li Cas Technology, Daim Ntawv Thov, thiab Cov Nqi Uas Muaj Feem Xyuam Nqi?
Ntau lub tuam txhab muaj kev txhawj xeeb heev txog tus nqi ntawm RFID tag, tab sis tus nqi ntawm RFID tags cuam tshuam los ntawm ntau yam xws li cov khoom siv, qhov loj me, zaus, nti hom, txheej txheem tsim khoom thiab yuav khoom kom muaj nuj nqis, thiab tsis tuaj yeem muab cov nqi sib koom ua ke. Tus sau hauv qab no yuav txheeb xyuas tus nqi ntau thiab cuam tshuam raws li qhov xwm txheej hauv kev ua lag luam, vam tias yuav pab tau txhua tus.
01
Hom ntawv cim thiab kev ua haujlwm zaus
Raws li kev khiav hauj lwm zaus, RFID tags feem ntau muaj plaub pawg: tsawg zaus (LF), siab zaus (HF), ultra-siab zaus (UHF) thiab microwave.
(1) Tsawg zaus (LF, 125 - 134 kHz): Tus nqi feem ntau yog kim dua, feem ntau yog siv rau hauv cov xwm txheej xws li kev taug qab tsiaj, nkag mus rau cov ntawv tswj, thiab lwm yam, thiab tus nqi yuav txawv ntawm ob peb yuan mus rau ntau tshaj kaum yuan.
(2) High zaus (HF, 13.56 MHz): Qhov chaw siv dav tshaj plaws, npog NFC, kev tswj hwm phau ntawv, daim npav them nyiaj, daim npav tswj xyuas thiab lwm yam. Tus nqi ntau yog loj, nrog cov ntawv yooj yim lossis cov cim npe qis li 0.5 yuan mus rau 2 yuan, thiab cov uas muaj encryption, tshwj xeeb qhov ntau thiab tsawg los yog kev ua tau zoo yuav ncav cuag ob peb yuan los yog ntau tshaj kaum yuan.
(3) UHF (UHF, 860 - 960 MHz): Feem ntau yog siv rau hauv kev xa khoom, chaw khaws khoom, khw muag khoom, thiab kev tswj cov cuab yeej cuab tam, vim nws qhov ntev ntawm kev nyeem ntawv thiab batch nyeem ntawv, tam sim no yog daim ntawv thov loj tshaj plaws thiab cov nqi sib tw hnyav tshaj plaws.
(4) Microwave (2.45GHz, 5.8GHz, thiab lwm yam): Kev nyeem ntawv nrug ntev heev (txog kaum ntawm meters mus rau 100 meters), tus nqi yog siab, thiab nws feem ntau yog siv rau cov cim npe, xws li tsheb ntev - txheeb xyuas qhov deb.
Piv txwv li, cov ntawv yooj yim tshaj plaws / cov khoom siv hluavtaws (siv rau cov khw muag khaub ncaws thiab cov ntawv logistics lub thawv) tuaj yeem qis li 0.2 ~ 0.8 yuan los yog qis dua thaum muaj ntau ntau; Tus nqi ntawm kev tiv thaiv- cov ntawv hlau (siv rau kev txuas rau cov hlau nto) tau nce ntau, feem ntau ntawm 1.5 ~ 10 yuan, lossis ntau dua, nyob ntawm qhov loj, cov khoom siv, thiab kev ua haujlwm; High -cov ntawv tiv thaiv kub thiab cov ntawv tshwj xeeb (xws li ceramics, PCBs) yog kim dua, uas tej zaum yuav txawv ntawm ob peb yuan mus rau kaum tawm yuan.
02
Chip kev ua tau zoo thiab muaj peev xwm
Ib qho tseem ceeb tshaj plaws ntawm RFID tags yog cov nti, thiab nws qhov chaw cia, kev ua tau zoo, qauv, thiab lwm yam yuav cuam tshuam rau tus nqi.
(1) Qhov chaw cia: Muaj ntau qhov tshwj xeeb xws li 96-ntsis, 512-ntsis, 4K, 8K, thiab lwm yam.
(2) Encryption muaj nuj nqi: Txawm hais tias tsis muaj kev txhawb nqa encryption (xws li kev ruaj ntseg nta ntawm Gen2v2) yuav cuam tshuam ncaj qha rau tus nqi.
(3) Chip hom thiab qauv: xws li Impinj, NXP, Alien, Huahong, thiab lwm yam., RFID cim npe rau siab -kev ua tau zoo lossis siab - chips kev ruaj ntseg yog kim dua.
03
Ntim cov ntaub ntawv thiab cov ntawv
Cov khoom ntim sib txawv thiab txoj hauv kev kuj tseem yuav sib txawv ntawm tus nqi RFID kawg. Tshwj xeeb, nws yog manifested li:
(1) Cov ntaub ntawv: suav nrog cov ntawv zoo tib yam, cov ntawv hluavtaws, PET, PVC, ABS yas, epoxy resin, ceramics, thiab lwm yam. Qhov siab dua qhov yuav tsum tau ua rau huab cua tsis kam, kua muag tsis kam, kub tsis kam, tshuaj tiv thaiv corrosion, thiab lwm yam, tus nqi kim dua.
(2) Daim ntawv: muaj cov ntawv nplaum txheem txheem, phaib, khawm, ntawv ntxhua khaub ncaws, implantable iav raj daim ntawv lo, cable khi daim ntawv lo, hang tags, anti- cov ntawv hlau, thiab lwm yam. Cov ntaub ntawv pob tshwj xeeb nce nqi.
(3) Loj: Feem ntau, qhov me me lossis qhov xav tau rau cov duab tshwj xeeb, tus nqi siab dua.
04
Scenario xav tau thiab yuav khoom kom muaj nuj nqis
Nyob rau hauv lub ntsej muag ntawm cov kev cai tshwj xeeb ntawm qee qhov kev thov, xws li kev nyeem ntawv ntev dua, kev kub siab ua haujlwm (siv rau hauv tsheb log tsheb taug qab, kev lag luam ntxhua khaub ncaws), tsis kub tsis kam, tsis muaj dej, tshuaj tiv thaiv corrosion, UV tiv thaiv, tiv thaiv - cuam tshuam, thiab lwm yam., RFID tag nqi kuj tseem yuav nce ntxiv.
Tsis tas li ntawd, kev yuav khoom kom muaj nuj nqis kuj yog ib qho tseem ceeb cuam tshuam rau tus nqi, thiab RFID tag tus nqi yog qhov tseem ceeb heev rau kom muaj nuj nqis. Feem ntau hais lus, tus nqi ntawm cov qauv / cov khoom me me (ntau txog rau pua pua) RFID cim npe yog siab heev, uas tej zaum yuav yog ob peb zaug lossis ntau dua kaum npaug ntau dua li qhov loj - teev kev yuav khoom; Chav tsev nqi ntawm cov khoom nruab nrab (txhiab rau kaum tawm txhiab) RFID cim npe tau poob qis heev. Loj - nplai (ntau tshaj 100,000 daim) cov ntawv tuaj yeem tau txais tus nqi qis tshaj plaws, thiab UHF cov ntawv tuaj yeem qis heev hauv ultra- cov khoom loj (xws li ntau lab daim).
Qhov tseeb, cov nqi tsim khoom, kev tswj kom zoo, thiab cov nqi them nqi ntawm cov neeg muag khoom sib txawv kuj tseem yuav cuam tshuam rau tus nqi ntawv kawg. Tsis tas li ntawd, tus nqi ntawm RFID tej yaam num suav nrog tsis tsuas yog lub cim npe xwb, tab sis kuj yog tus nyeem ntawv, kav hlau txais xov, nruab nrab, software system, kev pabcuam kev sib koom ua ke, thiab lwm yam. Cov nqi sau npe yuav tsis suav rau cov haujlwm loj, tab sis lawv tseem ceeb heev hauv cov khoom muag khoom - qib kev siv. Yog li ntawd, nws raug nquahu kom xav txog kev xaiv raws li koj tus kheej xav tau thiab pob nyiaj siv.
