RFID Tag Kev Txhim Kho Ntawm
Jul 03, 2017

Tuam Tshoj tus RFID kev lag luam tom qab ntau tshaj li kaum xyoo ntawm txoj kev loj hlob, RFID Tag thiab tam sim no kev siv technology lawm ntau paub tab, tshwj xeeb tshaj yog hauv ob lub xyoo dhau los, RFID Luam nyob hauv lub teb chaws kom mob siab thiab txhawb kev loj hlob ntawm kev lag luam tom qab, nrog ntau yam nyob rau hauv Internet ntawm tej yam uas txuas ntxiv mus txhawb nws Kev Tswj ib tug khov kho hauv txoj kev loj hlob.

RFID feem ntau cov qauv, RFID Luam qhov kev lag luam tseem mus txog qhov kev pom zoo. Tam sim no, feem ntau cov nquag muaj thoob ntiaj teb yog 13.56 MHz, 13.56 MHz high-frequency RFID tshuab vim kev kawm ruaj khov, tsim nyog tus nqi, qhov ntau ntawm nws cov kev nyeem ntawv nrug thiab qhov ntau ntawm daim ntawv thov kom phim, RFID Tag thiab yog li nyob hauv npav daim npav, kev them nyiaj mobile tau them Cov Ntawv Thov, tshwj xeeb yog hauv Kauslim, Nyiv thiab lwm qhov chaw.

RFID cim npe feem ntau siv hauv cov npuas hlau. Thaum cov ntawv cim RFID nyob ze rau cov hlau, cov hlau muaj lub zog zoo rau lub tshuab electromagnetic, RFID Tag kom lub teeb liab tsis muaj zog thiab qhov kev nyeem ntawv nrug ua closer. Muaj ib qho teeb meem ntawm daim card tsis ua hauj lwm. Kev daws teeb meem tam sim no yog muab cov ntaub ntawv ntxig rau sab nraum qab ntawm cov khoom siv hlau nplaum sib nqus.

Cov ntaub ntawv pov thawj hauv cov khoom siv hluav taws xob txo ntawm kev siv hluav taws xob, nqus dej thiab EMC thiab lwm yam kev siv ntau dua, thiab cov kws txawj piav txog lawv txoj haujlwm ua haujlwm tau ua ntau ntau qauv, tsim ntawm ntau cov kev paub theoretical, tab sis qhov teeb meem yog tias cov kev xav Ntau txoj haujlwm, RFID Tag qee cov neeg tsis paub nyeem hauv daim teb no tsis yooj yim to taub.

RFID txoj cai muaj ib qho hluav taws xob lossis daim npav hu ua tsis cuag ncua (xws li smartphone nrog ib daim credit card) uas tau muab tso rau ntawm qhov khoom thiab cov cuab yeej siv rau kev qhia ntawv rau hauv daim ntawv cim khoom hluav taws xob thiab kev sau cov lus qhia tawm los ntawm cov ntawv sau hluav taws xob, hu ua RFID nyeem ntawv los yog nyeem ntawv uas muaj ob ntu. Raws li pom hauv daim duab 1, thiaj li tso cai rau lwm cov khoom siv los tso saib lossis siv cov ntaub ntawv no, RFID Tag tus nyeem ntawv kuj tuaj yeem ntsia tau rau sab nraud interface nrog RS232 raws tu qauv, yog li ntawd koj tuaj yeem txuas lus nrog lwm cov cuab yeej.

Vim tias cov ntawv cim lub npe, RFID Tag ces cov cim npe thiab cim xeeb yuav tsum tau ua haujlwm rau lub zog ntawm tus nyeem ntawv, tus nyeem ntawv thiab kev sib txuas lus hluav taws xob ntawm kev sib txuas ntawm kev sib txuas ntawm electromagnetic ua kom tiav, kev siv hluav taws xob hluav taws xob los ntawm nyeem ntawv coil kav hlau txais xov los ntawm kev sib txuas ntawm electromagnetic.

Qhov siab tshaj plaws electromagnetic teb yog tsim los ntawm tus nyeem ntawv lub kav hlau txais xov coil, thiab tom qab ntawd lub sib nqus teb dhau los ntawm kev sib tsoo ntawm qhov kev sib tshuam thiab qhov chaw nyob ib ncig ntawm lub chaw txias. RFID Tag Raws li kev siv ntawm daim ntawv qhia zaus ntawm 13.56 MHz, lub wavelength ntawm 22.1m, deb tshaj tus nyeem ntawv kav hlau txais xov thiab daim ntawv cim huab cua, yog li nyeem ntawv mus rau lub kav hlau txais xov nyob nruab nrab ntawm lub electromagnetic teb raws li ib qho yooj yim alternating magnetic teb nrog.

Los ntawm kev hloov ntawm cov khoom siv hluav taws xob hluav taws xob sib tshooj thiab cov capacitor ua rau ib qho kev sib tshuam resonant, tuned rau tus nyeem ntawv tau kev tso cai kev sib txuas ntau zaus ntawm 13.56 MHz, RFID Tag thiaj li raws li lub voj resonance, lub npe coil inductor rau ntawm qhov hluav taws xob generated los ntawm qhov siab tshaj plaws. Thiab qhov ua tiav ntawm lub hwj huam hloov ntawm cov kav hlau txais xov hluav taws xob thiab daim pib hluav taws xob ntawm tus nyeem ntawv yog sib luag ntawm cov xov tooj ntawm cov kauj ntawm lub koos, qhov cheeb tsam uas khi ntawm lub kauj voj, qhov sib txheeb ze ntawm ob qhov chaw, RFID Tag thiab qhov deb ntawm txhua lwm yam. RFID tag nyeem ntawv nrug muaj qee yam txwv vim yog vim li cas.

RFID tag nyeem ntawv nrug tsis yog tsuas yog ntsig txog lawv tus kheej, tab sis kuj nrog nws cheeb tsam muaj kev sib raug zoo heev. Hauv kev siv cov xov tooj cua ntawm cov xov tooj cua inductively, feem ntau ua li qhov kev thov: tus nyeem ntawv lossis cov xov tooj hluav taws xob xa nruab siab ncaj qha rau ntawm qhov chaw hlau. RFID Tag Txawm li cas los xij, nws tseem tsis tau los txuas rau cov hlau nplaum hluavtaws ncaj qha rau ntawm cov hlau.
