Thaum siv RFID systems, tib neeg feem ntau tsom mus rau kev nyeem ntawv deb, tag loj, kev khiav hauj lwm zaus, los yog nti hom, yooj yim saib lwm yam tseem ceeb cuam tshuam rau txoj haujlwm ua tiav -RFID nco. Qhov tseeb, cov ntaub ntawv dab tsi ntawm RFID tag tuaj yeem khaws thiab cov ntaub ntawv sib txawv li cas tau faib ncaj qha cuam tshuam rau lub koom haum cov ntaub ntawv thiab kev ua kom muaj peev xwm yav tom ntej.
Rau kev lag luam xws li warehousing thiab logistics, industrial manufacturing, asset management, kho mob, thiab khw muag khoom, kev nkag siab txog cov ntsiab lus ntawm RFID nco tsis tsuas yog pab xaiv cov cim npe RFID uas tsim nyog tab sis kuj ua kom tag nrho cov kab ke ua haujlwm zoo dua thiab ruaj khov.
RFID Memory yog dab tsi?
RFID nco yog hais txog qhov chaw khaws cia hauv RFID nti siv los khaws cov ntaub ntawv. Vim yog kev siv cov cuab yeej uas tsis yog- tsis hloov pauv, cov ntaub ntawv sab hauv tuaj yeem khaws cia ntev - lub sijhawm txawm tias lub cim raug txiav tawm ntawm lub hwj chim. Thaum tus nyeem ntawv RFID tsim kev sib txuas lus nrog lub cim, nws nkag mus rau ntau qhov chaw khaws cia hauv lub nti raws li kev sib txuas lus, nyeem cov ntaub ntawv tus kheej lossis sau cov ntaub ntawv lag luam. Ntau homRFID tagtej zaum yuav muaj peev xwm siv tau los ntawm kaum tawm bytes mus rau ntau txhiab bytes; yog li ntawd, nws yog ib qho tsim nyog los xaiv cov nti tsim nyog raws li cov ntaub ntawv ntim thaum pib ntawm qhov project.
Rau UHF RFID cim npe raws li EPC Chav Kawm 1 Gen 2 tus qauv, cov nti feem ntau siv cov qauv Memory Bank qauv, ua kom muaj kev sib raug zoo nrog cov neeg nyeem los ntawm ntau hom.
Vim li cas RFID chips siv partitioned cia?
RFID tags yuav tsum sib npaug ntawm kev txheeb xyuas sai, kev tswj xyuas kev ruaj ntseg, thiab kev saib xyuas cov ntaub ntawv. Yog li ntawd, lub nti sab hauv qhov chaw tsis yog ib qho chaw txuas ntxiv tab sis tau muab faib ua ntau thaj chaw ua haujlwm ywj pheej.
Qhov zoo tshaj plaws ntawm qhov tsim no yog qhov sib txawv ntawm cov ntaub ntawv tuaj yeem tswj hwm nyias. Piv txwv li, cov lej ntawm cov khoom lag luam yuav tsum tau nyeem ntau zaus, cov cim nti tsis tuaj yeem hloov kho, thiab kev lag luam - cov ntaub ntawv tau hais tseg yuav tsum txhawb kev sau ntawv rov qab. Yog tias tag nrho cov ntaub ntawv no khaws cia rau hauv tib qhov chaw, nws yuav tsis tsuas yog txo cov kev nyeem ntawv tab sis kuj yooj yim ua rau cov ntaub ntawv tsis sib haum xeeb.
Reserved Memory: Tag Access Management
Reserved Memory tuaj yeem nkag siab tias yog thaj chaw tswj hwm kev nyab xeeb ntawm RFID tag. Nws tsuas yog khaws cov passwords nkag thiab rhuav tshem cov passwords, uas yog qhov tseem ceeb rau kev tswj hwm kev nkag mus. Tus password nkag mus txwv cov khoom siv twg muaj kev tso cai los hloov kho lub cim npe, thaum tus password puas tsuaj tuaj yeem ua tsis tau lub cim mus tas li hauv qhov xwm txheej tshwj xeeb, tiv thaiv kev nyeem cov ntaub ntawv ntxiv.
EPC Nco: Lub Ntsiab ntawm RFID System Identification
EPC Memory yog qhov chaw khaws cia tseem ceeb tshaj plaws ntawm RFID cim npe thiab cov ntaub ntawv cov ntsiab lus nkag los ntawm cov neeg nyeem los ntawm lub neej ntawd. EPC (Electronic Product Code) tuaj yeem nkag siab tias yog tus cim tshwj xeeb rau cov khoom hauv RFID system. Cov ntawv thov xws li cov khoom lag luam hauv tsev khaws khoom, cov khoom nkag thiab tawm, thiab kev tsim cov khoom lag luam feem ntau cia siab rau EPC rau kev txheeb xyuas sai.
Lub chaw logistics tuaj yeem tshawb xyuas ntau pua txhiab yam khoom txhua hnub. Cov neeg nyeem feem ntau tsis nyeem cov ntaub ntawv ua lag luam ua tiav tab sis tau txais EPC code sai sai, tom qab ntawd nug cov ntaub ntawv khoom siv los ntawm cov ntaub ntawv rov qab. Qhov no txo tus nqi ntawm cov ntaub ntawv xa mus wirelessly thiab txhim kho batch kev txheeb xyuas efficiency.
TID Nco: Ib Daim Npav Chip ID uas tsis tau luam tawm
Ntxiv rau EPC, txhua daim RFID nti muaj tus cim tshwj xeeb sau ntawm lub Hoobkas, hu ua TID (Tag Identifier). TIDs yog ua ntej- sau los ntawm cov chaw tsim khoom chip thiab feem ntau tsis tuaj yeem hloov kho. Lawv muaj cov chip manufacturers code, cov qauv khoom, thiab cim serial tooj.
Vim nws qhov tsis sib xws, ntau thiab ntau lub tuam txhab siv TIDs los tiv thaiv -kev lees paub cuav. Piv txwv li, thaum ob qho tib si EPC thiab TID raug khi rau hauv cov ntaub ntawv, txawm tias ib tug neeg luam cov ntaub ntawv EPC, lawv tsis tuaj yeem luam tawm cov ntaub ntawv ntawm tus kheej, yog li txhim kho tag nrho cov kev ruaj ntseg thiab kev ntseeg tau.
Tus neeg siv Memory: Raws li cov ntaub ntawv khaws cia xav tau
Tsis yog txhua cov ntaub ntawv yuav tsum tau muab khaws cia rau hauv cov ntaub ntawv backend. Qee qhov kev lag luam nyiam khaws qee cov ntaub ntawv lag luam ncaj qha hauv RFID lossis. Qhov no yog qhov uas Tus Neeg Siv Memory tuaj txog. Tus Neeg Siv Memory yog thaj chaw nyeem tau yooj yim thiab sau tau, tso cai rau cov tuam txhab khaws ntau cov ntaub ntawv raws li kev xav tau ntawm kev lag luam, xws li cov lej ntau lawm, cov ntaub ntawv khaws cia, cov txiaj ntsig kuaj, kev thauj mus los, cov khoom siv tsis zoo, lossis cov ntaub ntawv tshuaj xyuas.
Piv txwv li, thaum lub sij hawm tu cov cuab yeej, engineers tuaj yeem ncaj qha sau lub sij hawm kho tshiab rau lub cim npe. Txawm tias tsis muaj kev sib txuas hauv network ntawm - qhov chaw, lawv tseem tuaj yeem nug cov cuab yeej siv cov ntaub ntawv keeb kwm ntawm RFID nyeem ntawv.
RFID Memory siv nyob rau hauv ntau daim ntawv thov
Logistics thiab warehousing precipitate ceev ceev EPC nyeem ntawv kom paub batch zoo; yog li ntawd, cov cim npe feem ntau khaws cov ntaub ntawv tseem ceeb xwb.
Cov tuam txhab tsim khoom tuaj yeem siv Tus Neeg Siv Memory los sau cov nodes tseem ceeb hauv cov txheej txheem tsim khoom, txhim kho ntawm -kev tswj hwm qhov chaw.
Hauv cov teb xws li cov cuab yeej kho mob thiab kev tswj xyuas cov qauv kuaj, TID (Trusted ID) thiab cov txheej txheem cryptographic tau muab tso ua ke rau kev lees paub thiab kev tswj xyuas kev nkag, ua kom cov ntaub ntawv muaj kev ncaj ncees thiab tiv thaiv kev hloov pauv tsis raug cai.
Nws yog qhov tseeb tias txoj kev nco siv sib txawv rau tib lub RFID daim ntawv hla kev lag luam sib txawv.
Yuav ua li cas xaiv txoj cai RFID Memory Configuration rau koj qhov project?
Yog tias koj lub tuam txhab twb muaj cov ntaub ntawv rov qab muaj zog thiab RFID cov cim npe feem ntau yog siv rau kev txheeb xyuas sai, tus qauv EPC khaws cia yog txaus. Yog tias yuav tsum tau khaws cov ntaub ntawv offline, chips nrog Cov Neeg Siv Memory yuav tsum tau ua ntej.
Rau cov ntawv thov cuam tshuam nrog kev tiv thaiv- cuav, tiv thaiv- cuav, thiab kev taug qab cov cuab yeej cuab tam, nws yog ib qho tseem ceeb uas yuav tau txiav txim siab seb TID puas txhawb qhov kev lees paub tshwj xeeb thiab seb Lub Cim Nco Nco tau ua raws li kev tswj hwm tus password. Kev txiav txim siab dav dav ntawm cov ntaub ntawv muaj peev xwm, kev ruaj ntseg, thiab kev ua haujlwm ntawm lub cev yog qhov tseem ceeb kom paub txog tus nqi ntawm RFID thev naus laus zis.
