Nyob rau hauv cov nqe lus ntawm wireless Radio Frequency Identification, cov nquag ua hauj lwm zaus muaj xws li 125KHZ, 13.56MHz, 869.5MHz, 915.3MHZ, 2.45GHz thiab lwm yam, sib xws rau: tsawg zaus (LF), siab zaus (HF), ultra siab zaus (UHF), microwave (MW).Txhua zaus band tag muaj cov txheej txheem sib xws: piv txwv li, 13.56MHZ muaj ISO15693, 14443 raws tu qauv, thiab ultra-high zaus (UHF) muaj ob txoj kev cai xaiv.Ib qho yog ISO18000-6B, thiab lwm qhov yog EPC C1G2 tus qauv uas tau lees paub los ntawm ISO raws li ISO18000-6C.
ISO18000-6B tus qauv
Cov yam ntxwv tseem ceeb ntawm tus qauv suav nrog: tus qauv paub tab, cov khoom ruaj khov, thiab daim ntawv thov dav;Tus lej ID yog qhov tshwj xeeb hauv ntiaj teb;nyeem tus lej ID ua ntej, tom qab ntawd nyeem cov ntaub ntawv cheeb tsam;muaj peev xwm loj ntawm 1024bits lossis 2048bits;cov neeg siv loj cov ntaub ntawv cheeb tsam ntawm 98Bytes lossis 216Bytes;ntau lub cim nyob rau tib lub sij hawm Nyeem, txog li kaum ob lub cim tuaj yeem nyeem tib lub sijhawm;cov ntaub ntawv nyeem ceev yog 40kbps.
Raws li cov yam ntxwv ntawm ISO18000-6B tus qauv, hais txog kev nyeem ntawv ceev thiab cov ntawv sau, cov ntawv thov siv ISO18000-6B tus qauv tuaj yeem ua tau raws li cov kev xav tau hauv cov ntawv thov nrog cov ntawv me me xws li kev ua haujlwm bayonet thiab chaw nres nkoj.Cov ntawv cim hluav taws xob uas ua raws li ISO18000-6B tus qauv feem ntau yog tsim rau kev tswj hwm kaw, xws li kev tswj cov khoom vaj khoom tsev, tsim hluav taws xob hauv tsev rau kev txheeb xyuas lub thawv, daim ntawv tso cai hluav taws xob, thiab daim ntawv tsav tsheb hluav taws xob (daim npav tsav tsheb), thiab lwm yam.
Qhov tsis txaus ntawm ISO18000-6B tus qauv yog: kev txhim kho tau nyob ruaj khov nyob rau xyoo tas los no, thiab tau hloov los ntawm EPC C1G2 hauv ntau daim ntawv thov;software curing technology ntawm cov neeg siv cov ntaub ntawv tsis yog mature, tab sis nyob rau hauv cov ntaub ntawv no, cov neeg siv cov ntaub ntawv yuav embedded thiab daws los ntawm nti manufacturers thiab.
ISO18000-6C (EPC C1G2) tus qauv
Daim ntawv cog lus suav nrog kev sib xyaw ntawm Class1 Gen2 tau tsim los ntawm Lub Ntiaj Teb Cov Khoom Code Center (EPC Ntiaj Teb) thiab ISO / IEC18000-6 launched los ntawm ISO / IEC.Cov yam ntxwv ntawm tus qauv no yog: ceev ceev, cov ntaub ntawv tus nqi tuaj yeem ncav cuag 40kbps ~ 640kbps;tus naj npawb ntawm cov cim uas tuaj yeem nyeem tib lub sijhawm yog qhov loj, theoretically ntau dua 1000 cim tuaj yeem nyeem tau;thawj zaug nyeem EPC tus lej, tus lej ID ntawm daim ntawv yuav tsum tau nyeem nrog cov ntaub ntawv hom nyeem;muaj zog muaj nuj nqi, ntau txoj kev sau kev tiv thaiv, muaj zog ruaj ntseg;ntau qhov chaw, muab faib ua EPC cheeb tsam (96bits lossis 256bits, tuaj yeem txuas ntxiv mus rau 512bits), ID cheeb tsam (64bit lossis 8Bytes), thaj chaw neeg siv (512bit lossis 28Bytes)), password cheeb tsam (32bits lossis 64bits), muaj zog ua haujlwm, ntau txoj kev encryption , thiab muaj zog ruaj ntseg;Txawm li cas los xij, cov ntawv muab los ntawm qee lub tuam txhab tsis muaj cov ntaub ntawv siv cov ntaub ntawv, xws li Impinj cov ntawv lo.
Vim hais tias tus qauv EPC C1G2 muaj ntau yam zoo xws li muaj zog versatility, ua raws li cov cai EPC, cov khoom tsis tshua muaj nqi, thiab zoo compatibility.Nws yog qhov tsim nyog rau kev txheeb xyuas ntau ntawm cov khoom hauv kev lag luam logistics thiab yog nyob rau hauv kev txhim kho tas li.Nws yog tam sim no tus qauv tseem ceeb rau UHF RFID daim ntawv thov, thiab tau dav siv hauv phau ntawv, khaub ncaws, khw muag khoom tshiab thiab lwm yam lag luam.
Ob tus qauv no muaj lawv tus kheej zoo.Thaum ua qhov kev sib koom ua ke, koj yuav tsum sib piv lawv raws li koj tus kheej daim ntawv thov txoj kev xaiv tus qauv tsim nyog.
