Yuav ua li cas kom txo tau qhov teeb meem rfid tag misread?

Hauv cov txheej txheem thov tiag tiag, qhov kev nyeem ntawv ntawmCov ntawv cim UHFyog ib qho tseem ceeb heev. Vim tias kev nyeem ntawv ua ke, ntxiv rau kev nyeem ntawv ceev, seb nws puas tuaj yeem ua kom nyeem tau zoo tsis plam kev nyeem ntawv yog qhov tseem ceeb rau kev tswj hwm zoo.

Cov lus tseem ceeb: rfid daim ntawv lol；rfid nyeem ntawv；rfid kav hlau txais xov

Nrog rau kev siv RFID dav dav, nws tau nkag mus rau hauv txhua yam ntawm peb lub neej. Qhov zoo ntawm RFID thev naus laus zis yog tias nws tuaj yeem sau cov ntaub ntawv ntau yam sai sai yam tsis muaj kev sib cuag ncaj qha nrog cov khoom siv sensing. Txawm li cas los xij, txawm tias cov thev naus laus zis zoo tshaj plaws tuaj yeem ntsib "kev nyuaj siab". Hauv cov txheej txheem thov tiag tiag, qhov nyeem ntawv ntawm UHF daim ntawv lo yog qhov tseem ceeb heev. Vim tias kev nyeem ntawv ntau, ntxiv rau qhov nyeem ceev, seb nws puas tuaj yeem ua kom ntseeg tau tias kev nyeem ntawv zoo tsis plam kev nyeem ntawv yog qhov tseem ceeb rau kev tswj hwm zoo. Muaj ntau yam uas cuam tshuam rau qhov nyeem ntawv. Txawm hais tias hauv chav kuaj peb tuaj yeem ntsuas qhov deb nyeem ntawv thiab lub sijhawm nyeem ntawv ntawm 100% nyeem ntawv. Tsuav yog lub tshuab daim npav txiav txim siab, qhov chaw teeb tsa ntawm lub tshuab daim npav txiav txim siab, thiab daim ntawv lo, qhov deb, thiab kev taw qhia ntawm lub kav hlau txais xov tooj raug txiav txim siab. Qhov nyeem ntawv tuaj yeem lav tau. Tab sis thaum siv tiag tiag, qhov xwm txheej nyuaj dua.

Yog li ntawd, thaum lub RFID antenna tiag tiag, RFID nyeem ntawv teeb tsa thiab debugging txheej txheem. Qhov chaw ntawm txhua lub antennas, lub kaum sab xis ntawm qhov chaw ntawm cov khoom, thiab qhov chaw ntawm RFID nyeem ntawv yuav tsum tau debuggable thiab txheeb xyuas dua. Yuav kom tau txais qhov ntsuas qhov deb zoo tshaj plaws, qhov nyeem ntau ntawm daim npav nyeem ntawv kuj yuav tsum tau hloov kho raws li qhov xav tau tiag tiag. Qhov nyeem ntau tsis yog qhov loj dua qhov zoo dua, nws yuav tsum tau khaws cia rau hauv qee qhov ntau. Kuj tseem muaj qhov chaw thiab kev coj ntawm cov khoom thaum yuav khoom, uas kuj yog qhov tshwj xeeb. Tau kawg, tom qab siv lub antenna omnidirectional, qhov teeb meem ntawm lub antenna yuav tsis muaj zog, tab sis nws tseem muaj kev cuam tshuam.

Yuav kom txo qhov teeb meem ntawm RFID Label uas tsis nyeem tau, koj tuaj yeem pib los ntawm cov hauv qab no:

1. Siv cov txheej txheem txhim kho kev nyeem ntawv

Hauv cov chaw uas muaj hlau thiab kua cuam tshuam ntau heev, cov thev naus laus zis txhim kho kev nyeem ntawv xws li cov kav hlau txais xov thiab cov nyeem ntawv txhim kho tuaj yeem siv los txhim kho lub peev xwm ntawm lub kaw lus kom nkag mus thiab ruaj khov cov ntawv lo. Cov thev naus laus zis no tuaj yeem txhim kho qhov deb ntawm kev sib kis thiab kev nkag mus ntawm RFID cov teeb liab, yog li txo qhov xwm txheej ntawm kev nyeem tsis tiav ntawm daim ntawv lo.

2. Kev xaiv daim ntawv lo thiab kev kho kom haum

Kev xaiv daim ntawv lo RFID uas haum rau ib puag ncig tshwj xeeb yog ib qho tseem ceeb los txo qhov teeb meem ntawm kev nyeem tsis tiav. Thaum xaiv daim ntawv lo, yuav tsum xav txog cov yam xws li kev nqus ntawm cov khoom, qhov loj thiab cov duab ntawm daim ntawv lo. Rau cov chaw uas muaj kev xav tau tshwj xeeb, xws li cov xwm txheej uas muaj hlau lossis kua ntau dua, cov ntawv lo tsim tshwj xeeb tuaj yeem xaiv tau los txhim kho kev nyeem tau yooj yim.

3. Txhim kho qhov layout ntawm daim ntawv lo

Qhov kev teeb tsa tsim nyog ntawm RFID Daim Ntawv Cim yog qhov tseem ceeb rau kev txo qhov teeb meem ntawm kev nyeem tsis tiav. Kev zam qhov deb dhau thiab kev sib tshooj ntawm cov ntawv cim tuaj yeem txo qhov tshwm sim ntawm kev sib tsoo. Tsis tas li ntawd, qhov chaw thiab kev taw qhia ntawm daim ntawv cim kuj tseem tuaj yeem cuam tshuam rau kev nyeem ntawv. Yog li ntawd, thaum teeb tsa RFID Daim Ntawv Cim, nws yuav tsum tau ua kom ntseeg tau tias daim ntawv cim nyob rau hauv qhov chaw nyeem ntawv zoo tshaj plaws thiab kev taw qhia kom txhim kho qhov kev nyeem ntawv ua tiav.

4. Tsim thiab xa tawm Antenna

Kev tsim thiab kev xa tawm ntawm lub antenna muaj feem cuam tshuam loj heev rau kev nyeem RFID. Kev siv cov antennas uas tsim tau zoo thiab cov tswv yim xa tawm zoo tshaj plaws tuaj yeem txo qhov cuam tshuam ntawm ntau txoj kev cuam tshuam thiab cov teeb meem xws li hlau thiab kua rau ntawm cov teeb liab RFID. Los ntawm kev kho qhov kev taw qhia thiab lub kaum sab xis ntawm lub antenna, qhov kev cuam tshuam thiab kev txo qis ntawm cov teeb liab tuaj yeem txo qis mus rau qhov loj tshaj plaws, thiab lub peev xwm ntawm tus nyeem ntawv kom raug nyeem daim ntawv lo tuaj yeem txhim kho.

5. Kev tswj hwm spectrum zoo tshaj plaws

Cov txheej txheem RFID ua haujlwm hauv lub spectrum wireless thiab yooj yim rau kev cuam tshuam los ntawm lwm cov khoom siv hluav taws xob. Los ntawm kev npaj thiab kev tswj hwm ntawm cov zaus spectrum siv los ntawm RFID system, kev xaiv cov zaus bands tsis muaj neeg siv lossis kev siv cov thev naus laus zis spectrum hopping tuaj yeem txo qhov cuam tshuam ntawm kev cuam tshuam ntawm cov teeb liab, yog li txhim kho qhov kev vam meej ntawm kev nyeem RFID Label.
