Keeb Kwm & Daim Ntawv Thov
Thaum tswj hwm ntau yam khoom muaj nqis, suav nrog cov tshuab, kev thauj mus los, thiab cov khoom siv hauv chaw ua haujlwm, cov txheej txheem suav nyiaj ib txwm siv rau kev tswj hwm cov khoom muaj nqis yuav tsum siv sijhawm thiab zog ntau. Kev siv RFID thev naus laus zis tuaj yeem ua kom zoo thiab sau cov xwm txheej ntawm cov khoom muaj nqis ruaj khov, thiab nws ua rau kawm tau tiag tiag thaum lawv ploj lossis tsiv mus. Nws ua kom lub tuam txhab muaj zog heev rau qib kev tswj hwm cov khoom muaj nqis ruaj khov, txhim kho kev nyab xeeb ntawm cov khoom muaj nqis ruaj khov, thiab zam kev yuav cov tshuab uas muaj tib lub luag haujlwm. Tsis tas li ntawd nws txhim kho tus nqi siv cov khoom muaj nqis ruaj khov, uas yog qhov pab tau zoo rau kev txhim kho peev xwm tsim khoom thiab kev ua haujlwm zoo thiab tom qab ntawd txhim kho cov txiaj ntsig kev lag luam ntawm cov tuam txhab.
Cov ntawv thov hauv kev tswj hwm cov cuab tam
Nrog rau kev siv tshuab RFID, cov cim qhia txog kev siv xov tooj cua tsis siv neeg siv rau txhua yam khoom muaj nqis. Cov no UHF RFID cov cim npe khoom muaj nqis muaj cov lej tshwj xeeb uas muab kev txheeb xyuas tshwj xeeb rau cov khoom muaj nqis thiab lawv tuaj yeem khaws cov ntaub ntawv ntxaws ntxaws txog cov khoom muaj nqis ruaj khov suav nrog lub npe, piav qhia, tus kheej ntawm cov thawj coj thiab cov ntaub ntawv ntawm cov neeg siv. Cov cuab yeej nyeem ntawv thiab sau ntawv RFID tes thiab ruaj khov yog siv rau kev ua tiav kev tswj hwm thiab kev sau khoom zoo. Cov khoom siv no txuas nrog RFID lub kaw lus tswj hwm cov khoom muaj nqis ruaj khov hauv keeb kwm yav dhau los, uas tuaj yeem tau txais, hloov kho thiab tswj cov ntaub ntawv khoom muaj nqis hauv lub sijhawm tiag tiag.
Ua li no, peb tuaj yeem ua tiav kev tswj hwm thiab kev sau cov khoom muaj nqis txhua hnub, lub voj voog ntawm cov khoom muaj nqis thiab kev siv tag nrho cov txheej txheem ntawm kev taug qab. Qhov no tsis yog tsuas yog txhim kho kev siv cov khoom muaj nqis xwb, tab sis kuj txhawb nqa kev tswj hwm cov ntaub ntawv thiab kev tswj hwm cov khoom muaj nqis, muab kev txhawb nqa cov ntaub ntawv tseeb rau cov neeg txiav txim siab.
Cov txiaj ntsig ntawm RFID hauv Kev Tswj Xyuas Khoom Muaj Nqis
1. Cov thawj coj uas muaj feem cuam tshuam muaj kev nkag siab zoo dua txog kev ntws ntawm cov cuab tam nrog cov cuab tam ruaj khov uas yooj yim dua, cov txheej txheem tswj hwm cov cuab tam yooj yim dua thiab kev tswj hwm zoo dua.
2. Thaum nrhiav cov khoom muaj nqis ruaj khov, qhov chaw ntawm cov khoom muaj nqis tuaj yeem txheeb xyuas tau meej. Thaum cov khoom muaj nqis ruaj khov tsis nyob hauv qhov ntau ntawm RFID nyeem tau, lub platform back-end tuaj yeem xa cov lus ceeb toom, uas txhim kho kev ruaj ntseg zoo heev thiab txo qhov kev pheej hmoo ntawm kev poob khoom muaj nqis lossis tub sab.
3. Muaj kev tiv thaiv zoo dua rau cov khoom muaj nqis uas zais cia heev, nrog rau cov neeg ua haujlwm uas tau xaiv los kom paub tseeb tias lawv yog leej twg kom tiv thaiv kev ua txhaum cai.
4. Nws txo cov nqi zog ua haujlwm uas yuav tsum tau siv rau kev tswj cov cuab tam thiab txhim kho kev ua haujlwm ntawm cov khoom muaj nqis, kev taug qab thiab kev tso chaw.
Kev Tshawb Fawb Txog Kev Xaiv Khoom
Thaum xaiv ib qho UHF passive RFID cim npe, nws yuav tsum xav txog qhov permittivity ntawm cov khoom txuas nrog rau qhov impedance ntawm RFID chip thiab RFID antenna. UHF tus kheej nplaum RFID cim npe feem ntau yog siv rau kev tswj cov cuab tam. Thaum rau qee cov cuab tam ruaj khov, cov cim npe hlau RFID raug siv vim tias cov khoom uas yuav txuas nrog yuav yog cov khoom siv hluav taws xob lossis hlau.
1. Cov khoom siv ntsej muag siv PET feem ntau. Rau cov kua nplaum, roj kua nplaum lossis 3M-467 tuaj yeem ua tau raws li qhov xav tau (SivRFID cim npe hlau mount yog tias nws txuas ncaj qha rau ntawm cov hlau, thiab PET + roj kua nplaum lossis 3M kua nplaum rau lub plhaub yas.)
2. Qhov loj me ntawm daim ntawv lo yog txiav txim siab raws li qhov loj me uas tus neeg siv xav tau. Cov khoom siv dav dav yog qhov loj me thiab qhov kev nyeem ntawv yuav tsum nyob deb. Qhov loj me ntawm RAIN RFID antenna nrog qhov nce loj dua yog 70 × 14mm thiab 95 × 10mm, ua tau raws li qhov yuav tsum tau ua.
3. Yuav tsum muaj lub cim xeeb loj dua. Ib lub chip nrog lub cim xeeb EPC ntawm 96 bits thiab 128 bits, xws li NXP Ucode 8, Ucode 9, Impinj M730, M750, Monza R6, Monza R6P, thiab lwm yam siv tau.
Cov Khoom Siv XGSun
Cov txiaj ntsig ntawmKev taug qab cov khoom muaj nqis nrog RFID cim npe muab los ntawm XGSun: Lawv ua raws li ISO18000-6C protocol, thiab tus nqi ntawm cov ntaub ntawv cim npe tuaj yeem ncav cuag 40kbps txog 640kbps. Raws li RFID anti-collision technology, theoretically, tus naj npawb ntawm cov cim npe uas tuaj yeem nyeem tau tib lub sijhawm tuaj yeem ncav cuag li 1000. Lawv muaj kev nyeem thiab sau ceev ceev, kev ruaj ntseg ntawm cov ntaub ntawv siab, thiab kev nyeem ntev txog li 10 meters hauv qhov ntau zaus ua haujlwm (860 MHz -960MHz). Lawv muaj peev xwm khaws cov ntaub ntawv loj, yooj yim nyeem thiab sau, muaj zog hloov pauv ib puag ncig, tus nqi qis, kev ua haujlwm siab, lub neej ua haujlwm ntev, thiab ntau yam kev siv. Nws kuj txhawb nqa kev hloov kho ntawm ntau yam qauv.
