Keeb Kwm & Daim Ntawv Thov
RFID thev naus laus zis yog ib qho kev qhia txog kev siv tshuab tsis siv neeg raws li cov teeb liab wireless thiab tsim nyog rau ntau yam kev thov. Nws tau txais kev saib xyuas ntau dua hauv cov tsev qiv ntawv, cov ntaub ntawv thiab kev tswj hwm archive. Los ntawm kev ntxiv RFID daim ntawv lo rau cov phau ntawv, cov ntaub ntawv thiab cov ntaub ntawv, cov haujlwm xws li kev nyeem ntawv tsis siv neeg, kev nug, kev xa rov qab thiab rov qab tuaj yeem ua tiav, txhim kho kev tswj hwm kev ua haujlwm thiab kev pabcuam qib ntawm cov ntaub ntawv cov ntaub ntawv.
Muaj ob hom ntawv tseem ceeb ntawm RFID cov ntawv siv hauv cov tsev qiv ntawv thiab cov ntaub ntawv khaws cia, RFID HF cov ntawv thiab RFID UHF cov ntawv. Ob daim ntawv lo no muaj cov yam ntxwv sib txawv. Cia kuv txheeb xyuas lawv qhov sib txawv hauv qab no:
RFID thev naus laus zis tuaj yeem muab faib ua ntau hom raws li kev ua haujlwm sib txawv: tsawg zaus (LF), siab zaus (HF), ultra siab zaus (UHF) thiab microwave (MW). Ntawm lawv, ntau zaus thiab ultra-siab zaus yog ob txoj kev siv RFID tshaj plaws tam sim no. Lawv txhua tus muaj lawv tus kheej qhov zoo thiab cov kev txwv, thiab muaj kev sib txawv hauv cov xwm txheej sib txawv.
Lub hauv paus ntsiab lus ua haujlwm: High-frequency RFID technology siv lub hauv paus ntsiab lus ntawm ze-field inductive coupling, uas yog, tus nyeem ntawv xa lub zog thiab pauv cov ntaub ntawv nrog lub cim npe los ntawm ib qho chaw sib nqus. UHF RFID thev naus laus zis siv lub hauv paus ntsiab lus ntawm cov hluav taws xob hluav taws xob nyob deb, uas yog, tus nyeem ntawv xa tawm lub zog thiab sib pauv cov ntaub ntawv nrog cov cim los ntawm cov hluav taws xob hluav taws xob.
Kev txheeb xyuas cov khoom
1. Chips:HF pom zoo kom siv NXP ICODE SLIX nti, uas ua raws li cov txheej txheem ISO15693 thiab ISO/IEC 18000-3 Hom 1. Nws muaj lub cim xeeb EPC loj ntawm 1024 khoom, tuaj yeem sau cov ntaub ntawv 100,000 zaug, thiab tuaj yeem khaws cov ntaub ntawv rau ntau tshaj 10 xyoo.
UHF pom zoo kom siv NXP UCODE 8, Alien Higgs 4, ua raws li cov txheej txheem ISO 18000-6C thiab EPC C1 Gen2, EPC, 128 ntsis cov neeg siv nco, uas tuaj yeem rov sau cov ntaub ntawv 100,000 zaug, thiab cov ntaub ntawv tuaj yeem txuag tau ntau dua 10 xyoo.
2. Kav hlau txais xov: HF kav hlau txais xov yog qhov sib luag, uas txo qhov cuam tshuam cuam tshuam ntawm ntau daim ntawv teev. Electromagnetic nthwv dej tuaj yeem hloov qee lub zog rau cov cim npe tom qab lawv los ntawm tus kav hlau txais xov. Lawv yog ultra-nyias nyob rau hauv tsos, tsis tshua muaj nqi, zoo heev nyob rau hauv kev ua tau zoo, thiab heev concealable. Yog li ntawd, HF cov ntawv tsim nyog rau kev tswj cov phau ntawv thiab cov thawv ntawv. Txawm li cas los xij, hauv ib nplooj ntawv tswj cov ntaub ntawv, nws yog siv rau cov ntaub ntawv tsis pub lwm tus paub, xws li cov ntaub ntawv zais saum toj kawg nkaus, cov ntaub ntawv tseem ceeb ntawm cov neeg ua haujlwm, cov duab kos duab, thiab cov ntaub ntawv tsis pub lwm tus paub. Tsuas muaj ib lossis ob peb nplooj ntawv hauv cov ntaub ntawv no. Kev siv HF cov cim npe yuav sib tshooj ze, ua rau muaj kev cuam tshuam kev cuam tshuam, cuam tshuam rau qhov raug lees paub, thiab ua tsis tau raws li kev tswj hwm. Hauv qhov no, nws raug nquahu kom siv cov tshuaj UHF daim ntawv lo.
3. Cov khoom siv nto: Ob leeg HF thiab UHF tuaj yeem siv cov ntawv kos duab ua cov khoom siv saum npoo av, thiab tuaj yeem luam cov ntawv, qauv lossis barcodes. Yog tias koj tsis xav luam tawm, koj tuaj yeem siv cov ntaub ntub dej ncaj qha.
4. Kua nplaum: Daim ntawv thov scenario ntawm cov cim npe feem ntau affixed rau ntawv. Nws yog ib qho yooj yim los lo thiab kev siv ib puag ncig tsis hnyav. Tsawg-qis kub yaj nplaum nplaum los yog dej kua nplaum feem ntau siv tau.
5. Tso daim ntawv:Feem ntau, glassine-rov qab daim ntawv nrog silicone roj txheej yog siv, uas tsis yog-nplaum thiab ua rau nws yooj yim los rhuav tshem tag.
6. Nyeem ntau: HF RFID thev naus laus zis yog qhov ze-tsawg inductive coupling thev naus laus zis, thiab nws cov haujlwm ua haujlwm me me, feem ntau hauv 10 centimeters. UHF RFID thev naus laus zis yog kev siv hluav taws xob hluav taws xob nyob deb. Electromagnetic yoj muaj qee qhov kev nkag mus thiab nws cov haujlwm ua haujlwm loj, feem ntau ntau dua 1 meter. Qhov kev nyeem ntawv deb ntawm HF yog me me, yog li nws tuaj yeem nrhiav tau cov phau ntawv lossis cov ntaub ntawv khaws cia kom raug.
7. Kev nyeem ntawv ceev: Vim muaj kev txwv ntawm txoj cai sib txuas ntawm qhov ze ntawm qhov chaw inductive, HF RFID thev naus laus zis muaj qhov kev nyeem ntawv qeeb thiab nws nyuaj rau nyeem ntau daim ntawv nyob rau tib lub sijhawm. Vim yog qhov zoo ntawm txoj cai hluav taws xob hluav taws xob hluav taws xob nyob deb, UHF RFID thev naus laus zis muaj kev nyeem ntawv nrawm dua thiab pab pawg nyeem ntawv ua haujlwm. UHF thev naus laus zis muaj qhov ntev ntawm kev nyeem ntawv thiab kev nyeem ntawv nrawm dua, yog li nws yuav ua tau zoo dua thaum khaws cov phau ntawv lossis cov ntaub ntawv.
8. Muaj peev xwm tiv thaiv kev cuam tshuam: Qhov ze-tsawg inductive coupling ntawm high-frequency RFID thev naus laus zis txo qhov muaj peev xwm cuam tshuam wireless, ua rau cov cuab yeej siv hluav taws xob ntau heev "tiv thaiv" rau ib puag ncig suab nrov thiab electromagnetic cuam tshuam (EMI), yog li nws muaj peev xwm tiv thaiv kev cuam tshuam. . UHF siv lub hauv paus ntsiab lus ntawm electromagnetic emission, yog li nws muaj kev cuam tshuam rau electromagnetic cuam tshuam. Tib lub sijhawm, hlau yuav cuam tshuam cov teeb liab thiab dej tuaj yeem nqus cov cim. Cov yam tseem ceeb no yuav cuam tshuam nrog kev ua haujlwm ib txwm muaj ntawm daim ntawv lo Txawm hais tias qee qhov UHF cov ntawv nplaum tom qab kev txhim kho thev naus laus zis muaj kev ua tau zoo hauv kev tiv thaiv kev cuam tshuam los ntawm cov hlau thiab cov kua dej, piv nrog cov ntawv ntim siab, UHF tseem me ntsis qis dua, thiab lwm txoj hauv kev yuav tsum tau siv rau ua rau nws.
9. Kev siv cov ntawv RFID ua ke nrog lub qhov rooj zoo li cov kab thiab cov tshuab tuaj yeem tiv thaiv cov phau ntawv thiab cov ntaub ntawv kom tsis txhob poob thiab siv lub tswb tshem tawm tsis raug cai.
HF thiab UHF RFID cov kev daws teeb meem txhua tus muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, thiab kev xaiv yuav tsum tau ntsuas thiab sib piv raws li cov kev xav tau tshwj xeeb thiab cov xwm txheej.
