Iyini I-Rfid Electronic Tag?

Amathegi e-elektroniki e-RFID zisetshenziswa kabanzi empilweni yansuku zonke yawo wonke umuntu kanye nemisebenzi yokukhiqiza. Akugcini nje ngokuthuthukisa kakhulu ukusebenza kahle kokukhiqiza, kodwa futhi kuletha ukunethezeka okuningi empilweni yansuku zonke yabantu. Ngakho-ke namuhla ngizokwethula omaka be-elektroniki be-RFID kuwe.

Indlela amathegi e-elektroniki e-RFID asebenza ngayo

Amathegi e-RFID asebenzisa ifrikhwensi yomsakazo engenantambo ukwenza ukudluliswa kwedatha okungeyona indlela yokuxhumana phakathi komfundi nekhadi lefrikhwensi yomsakazo ukuze kufezwe injongo yokuhlonza okuqondiwe nokushintshisana kwedatha. Okokuqala, ngemva kokuba ithegi ye-electronic ye-RFID ingene endaweni kazibuthe, ithola isignali yefrikhwensi yomsakazo ethunyelwa ngumfundi, bese isebenzisa Amandla atholwe amandla amanje athumela ulwazi lomkhiqizo olugcinwe ku-chip (umaka we-passive noma umaka wokwenziwa), noma ithegi ithumela ngokushesha isignali yefrikhwensi ethile (ithegi esebenzayo noma ithegi esebenzayo), bese umfundi efunda ulwazi futhi alukhiphe. Ekugcineni, ithunyelwa ohlelweni lolwazi olumaphakathi ukuze kucutshungulwe idatha efanele.

Ukwakhiwa kwamathegi e-elektroniki e-RFID

Umaka we-electronic we-RFID ophelele uqukethe izingxenye ezintathu: umfundi/umbhali, umaka we-electronic, kanye nesistimu yokuphatha idatha. Umgomo wayo wokusebenza ukuthi i-Reader ikhipha amandla egagasi lomsakazo wefrikhwensi ethile ukushayela isekethe ukuze ithumele idatha yangaphakathi. Ngalesi sikhathi, Isifundi Samukela futhi sihumushe idatha ngokulandelana bese siyithumela kuhlelo lokusebenza ukuze sicutshungulwe.

1. Umfundi

Umfundi uyithuluzi elifunda ulwazi kuthegi ye-electronic ye-RFID noma elibhala ulwazi umaka oludinga ukuligcina kuthegi. Kuye ngesakhiwo nobuchwepheshe obusetshenzisiwe, umfundi angaba idivayisi yokufunda/ukubhala futhi abe isikhungo sokulawula nokucubungula ulwazi sohlelo lwe-RFID. Lapho uhlelo lwe-RFID lusebenza, umfundi uthumela amandla efrikhwensi yomsakazo endaweni ukuze akhe inkambu ye-electromagnetic. Ubukhulu bendawo buncike emandleni okudlulisela. Amathegi angaphakathi kwendawo ehlanganisa umfundi ayacushwa, athumele idatha egcinwe kuwo, noma aguqule idatha egcinwe kuwo ngokwemiyalelo yomfundi, futhi angaxhumana nenethiwekhi yekhompiyutha ngesixhumi esibonakalayo. Izingxenye eziyisisekelo zomfundi ngokuvamile zihlanganisa: i-antenna ye-transceiver, i-frequency generator, i-loop evaliwe ngesigaba, i-modulation circuit, i-microprocessor, imemori, i-demodulation circuit kanye ne-peripheral interface.

(1) I-Transceiver Antenna: Thumela amasignali amafrikhwensi omsakazo kumathegi, futhi wamukele amasignali okuphendula kanye nolwazi lomaka olubuyiswe omaka.

(2) I-Frequency generator: ikhiqiza imvamisa yokusebenza yesistimu.

(3) Iluphu evaliwe yesigaba: yenza isignali yenkampani yenethiwekhi edingekayo.

(4) Isekhethi yokuguquguquka: Layisha isignali ethunyelwe kuthegi kugagasi lesithwali bese uyithumela ngesekhethi yefrikhwensi yomsakazo.

(5) I-Microprocessor: ikhiqiza isignali okufanele ithunyelwe kuthegi, inquma isignali ebuyisiwe umaka, futhi ithumele idatha ekhohliwe emuva kuhlelo lohlelo lokusebenza. Uma isistimu ibethelwe, futhi idinga ukwenza umsebenzi wokukhipha ukubethela.

(6) Inkumbulo: igcina izinhlelo zabasebenzisi kanye nedatha.

(7) Isekethe yokwehlisa: Yehlisa isignali ebuyiselwe umaka futhi iyithumele ku-microprocessor ukuze icutshungulwe.

(8) I-Peripheral interface: ixhumana nekhompyutha.

2. Ilebula ye-elekthronikhi

Amathegi e-elekthronikhi akhiwa ama-antenna e-transceiver, ama-circuits e-AC/DC, ama-demodulation circuits, ama-logic control circuits, inkumbulo kanye nama-modulation circuits.

(1) I-Transceiver Antenna: Thola amasignali avela kumfundi bese uthumela idatha edingekayo emuva kumfundi.

(2) Isekethe ye-AC/DC: Isebenzisa amandla kazibuthe kagesi akhishwa ngumfundi futhi iwakhipha ngesekhethi yokusimamisa kagesi ukuze inikeze amandla azinzile kwamanye amasekhethi.

(3) Isekethe ye-Demodulation: susa inkampani yenethiwekhi kusiginali eyamukelwe bese wehlisa isiginali yoqobo.

(4) Isifunda sokulawula okunengqondo: sinquma isignali kumfundi bese sibuyisela isignali ngokuvumelana nezidingo zomfundi.

(5) Inkumbulo: ukusebenza kohlelo nokugcinwa kwedatha yokuhlonza.

(6) Isekhethi yokuguquguquka: Idatha ethunyelwe yisekethe yokulawula enengqondo ilayishwa ku-antenna futhi ithunyelwe kumfundi ngemva kokulayishwa kusekethe yokushintshashintsha.

Izimpawu zamathegi e-RFID electronic

Ngokuvamile, ubuchwepheshe bokuhlonza ifrikhwensi yomsakazo bunezici ezilandelayo:

1. Ukusebenza

Ubuchwepheshe bethegi ye-RFID buncike kumagagasi kagesi futhi abudingi ukuthintana ngokomzimba phakathi kwezinhlangothi zombili. Lokhu kuvumela ukuthi isungule ukuxhumana futhi igcwalise ukuxhumana ngokuqondile kungakhathaliseki ukuthi uthuli, inkungu, ipulasitiki, iphepha, izinkuni kanye nezithiyo ezihlukahlukene.

2. Ukusebenza kahle

Isivinini sokufunda nokubhala sohlelo lomaka we-electronic we-RFID lushesha kakhulu, futhi inqubo evamile yokudlulisela i-RFID ngokuvamile ithatha ama-millisecond angaphansi kwe-100. Abafundi be-RFID be-high-frequency RFID bangakwazi ngisho nokukhomba futhi bafunde okuqukethwe komaka abaningi ngesikhathi esisodwa, bathuthukise kakhulu ukusebenza kahle kokudluliswa kolwazi.

3. Ubungqayizivele

Ithegi ngayinye ye-RFID ihlukile. Ngokubhalelana phakathi kwamathegi nemikhiqizo ye-RFID, amandla okujikeleza alandelayo omkhiqizo ngamunye angalandelelwa ngokucacile.

4. Ubulala

Omaka be-RFID banesakhiwo esilula, izinga eliphezulu lokuqashelwa, nemishini yokufunda elula. Ikakhulukazi njengoba ubuchwepheshe be-NFC buya ngokuya buduma kuma-smartphones, umakhalekhukhwini wawo wonke umsebenzisi uzoba umfundi we-RFID olula.

Kunolwazi oluningi mayelana namathegi e-elektroniki e-RFID. I-Joinet igxile ocwaningweni nasekuthuthukisweni kobuchwepheshe obuphakeme obuhlukahlukene iminyaka eminingi, isize ukuthuthukiswa kwezinkampani eziningi, futhi izimisele ukuletha izixazululo ezingcono zamathegi e-RFID kumakhasimende.
