dio frequency kev txheeb xyuas (RFID) thev naus laus zis tau hloov pauv txoj kev lag luam taug qab thiab tswj cov khoom muaj nqis, cov khoom muag thiab cov saw hlau. Lub hauv paus ntawm RFID system yog lub nti ntawm RFID tag, uas khaws thiab xa cov ntaub ntawv wirelessly los ntawm xov tooj cua tsis muaj zog. Xaiv lub nti zoo rau kojRFID daim ntawv lo yog qhov tseem ceeb rau txoj kev taug qab kom zoo thiab muaj txiaj ntsig. Hauv tsab xov xwm no, peb yuav tham txog cov ntsiab lus tseem ceeb uas yuav tsum tau xav txog thaum txiav txim siab tseem ceeb no.
1. Ntau zaus thiab cov qauv
Ua ntej, koj yuav tsum xav txog qhov ua haujlwm zaus ntawm RFID tag nti thiab cov qauv nws ua raws. Ntau zaus muaj xws li tsawg zaus (LF), siab zaus (HF) thiab ultra-siab zaus (UHF). Txhua qhov ntau zaus muaj nws qhov tshwj xeeb zoo, qhov tsis zoo thiab daim ntawv thov scenarios.
• LF RFID cim npe: Kev khiav hauj lwm zaus yog nyob rau hauv thaj tsam ntawm 125 kHz txog 135 kHz, kev nyeem ntawv thiab kev sau ntawv yog luv luv, thiab lub peev xwm nkag mus tau muaj zog. Qhov tsis zoo yog tias lub peev xwm tag nrho yog me me thiab tsuas yog tsim nyog rau cov ntawv teev npe qis thiab luv luv. Piv nrog HF RFID tags, tus naj npawb ntawm cov kav hlau txais xov tig ntau dua thiab tus nqi siab dua. Cov ntawv thov ntawm hom ntawv cim npe no suav nrog: kev txheeb xyuas tsiaj, kev txheeb xyuas lub thawv, kev txheeb xyuas cov cuab yeej, hluav taws xob tiv thaiv tub sab tub nyiag (lub tsheb yuam sij nrog cov khoom siv hauv transponder), thiab lwm yam.
• HF RFID cim npe: Hom kev khiav hauj lwm zaus: 13.56MHz. Nws muaj cov ntaub ntawv hloov pauv ceev ceev thiab tuaj yeem nyeem ntau lub cim npe tib lub sijhawm. Tab sis kev nyeem ntawv thiab kev sau ntawv nyob deb yog luv luv thiab kev nkag tau ntawm cov dej los yog cov khoom hlau tsis muaj zog. Nws feem ntau yog siv rau hauv cov xwm txheej xws li daim npav ntse, tswj tsev qiv ntawv thiab kev them nyiaj.
•UHF RFID cim npe Kev khiav hauj lwm zaus ntawm 860 MHz txog 960 MHz. Nws muaj kev nyeem ntawv ntev thiab sau ntawv nyob deb thiab muaj peev xwm xa cov ntaub ntawv ceev ceev. Qhov tsis zoo yog tias nws muaj qhov tsis muaj zog nkag mus rau cov dej lossis cov khoom siv hlau. Dav siv nyob rau hauv logistics nrhiav, tswj cov khoom muag thiab khw muag khoom lag luam.
Tsis tas li ntawd, koj kuj yuav tsum xav txog cov qauv RFID siv, xws li EPC Ntiaj Teb, ISO 18000, thiab lwm yam. Cov qauv no txhais cov cim loj, zaus, kev sib txuas lus thiab lwm yam ntxwv.
2. Kev nco thiab kev ua cov ntaub ntawv muaj peev xwm
RFID tag chips feem ntau muaj qhov sib txawv ntawm lub cim xeeb muaj peev xwm, xws li los ntawm ob peb bytes mus rau ntau KB. Thaum xaiv ib lub nti, koj yuav tsum xav txog tus nqi ntawm lub cim xeeb xav tau nrog rau cov ntaub ntawv khaws cia thiab kev ua haujlwm muaj peev xwm. Lub peev xwm loj dua tuaj yeem muab cov ntaub ntawv ntau qhov chaw khaws cia thiab ua lub zog, thiab tsim nyog rau daim ntawv thov scenarios uas yuav tsum tau taug qab ntau yam khoom.
3. Kev ruaj ntseg thiab kev ceev ntiag tug
Nws yog ib qho tseem ceeb heev los xyuas kom meej tias RFID tag nti muaj kev ruaj ntseg txaus thiab kev tiv thaiv kev ceev ntiag tug. Xav txog kev xaiv lub nti uas txhawb nqa kev nkag mus thiab nkag mus rau kev tswj hwm cov txheej txheem los tiv thaiv kev nyeem ntawv tsis raug cai thiab cuam tshuam. Tsis tas li ntawd, koj tuaj yeem xav txog kev npog ntsej muag lossis thaiv cov txheej txheem los txwv qhov kev nyeem tau ntau ntawm cov cim npe rau kev ruaj ntseg ntxiv.
4. Nqi thiab muaj
Thaum xaiv ib qho RFID tag nti, tus nqi thiab muaj yuav tsum tau txiav txim siab. Tus nqi ib txwm yog qhov tseem ceeb hauv kev txiav txim siab yuav khoom. Cov nqi sib txawv ntawm cov hom thiab cov qauv ntawm cov chips, thiab koj yuav tsum ntsuas lawv raws li koj cov peev nyiaj thiab daim ntawv thov xav tau. Nyob rau tib lub sijhawm, nws tseem ceeb heev kom ntseeg tau tias cov nti tau xaiv muaj cov khoom siv txhim khu kev qha thiab yooj yim rau kev koom ua ke rau hauv cov tshuab uas twb muaj lawm.
5. Kev xeem thiab kev lees paub
Kev ntsuam xyuas txaus thiab kev txheeb xyuas yog cov kauj ruam tseem ceeb ua ntej xaiv zaum kawg ntawm RFID tag chips. Qhov no suav nrog kev sim cov nti kev ua tau zoo, kev ntseeg siab thiab kev nyab xeeb hauv ntau qhov chaw thiab cov xwm txheej kom ntseeg tau tias nws ua tau raws li koj daim ntawv thov xav tau. Tsis tas li ntawd, koj tuaj yeem xa mus rau cov kev tshuaj xyuas thiab kev paub ntawm lwm tus neeg siv los ntsuas qhov tsim nyog ntawm koj cov nti xaiv.
6. Xav txog kev xav tau kev nthuav dav yav tom ntej
Raws li koj txoj kev lag luam thiab thev naus laus zis hloov zuj zus, koj yuav xav tau nthuav kojRFID qhov system los txhawb ntau lub zog los yog tuav cov ntaub ntawv ntau dua. Yog li ntawd, thaum xaiv ib tug RFID tag nti, thov xav txog yav tom ntej expansion xav tau thiab xaiv ib tug nti qauv nrog scalability. Qhov no yuav ua kom ntseeg tau tias lub kaw lus tuaj yeem hloov kho tau yooj yim rau kev hloov pauv thiab kev loj hlob yav tom ntej.
Cov ntsiab lus: Xaiv txoj cai RFID tag nti yuav tsum tau xav txog ntau yam, suav nrog zaus thiab cov qauv, kev nco thiab cov ntaub ntawv muaj peev xwm ua tau zoo, kev ruaj ntseg thiab kev ceev ntiag tug, tus nqi thiab muaj, kuaj thiab kuaj xyuas, thiab kev xav tau kev nthuav dav yav tom ntej. Los ntawm ua tib zoo tshuaj xyuas cov xwm txheej no thiab txiav txim siab paub raws li koj qhov kev xav tau ntawm daim ntawv thov, koj tuaj yeem xaiv qhov zoo tshaj plaws RFID tag nti rau koj qhov project.
