I-RFID (I-Radio Frequency Identification), umgomo wayo ukuxhumana kwedatha okungaxhumene phakathi komfundi nomaka ukuze kufezwe injongo yokuhlonza okuqondiwe.Uma nje kuyindlela yefrikhwensi yomsakazo, futhi ingabonakala ngale ndlela, ibalwa njengesigaba se-RFID.Ngokuvumelana nemvamisa, ingahlukaniswa ngokuvama okuphansi, imvamisa ephezulu, imvamisa ephezulu kakhulu, i-2.4G njalonjalo.I-RFID isetshenziswa kabanzi, nezinhlelo zokusebenza ezijwayelekile ezihlanganisa ukuphathwa kwezilwane, ukuphathwa kwemoto, ulayini wokukhiqiza, ukuphathwa kwempahla, ukuphathwa kwezisebenzi, nokunakekelwa kwezokwelapha okukhaliphile.
Ubuchwepheshe be-NFC (Near Field Communication) buqale kamuva kakhulu kune-RFID.Bekuwubuchwepheshe bokuxhumana obungenawaya bebanga elifushane obuthuthukiswa kakhulu ngabakwa-Philips, abakwaNokia kanye nabakwa-Sony ngonyaka ka-2003. Kuyindlela yokuxhumana yebanga elifushane ongathintani nayo.Imvamisa yokusebenza ngu-13.56MHz, futhi izinga lokuxhumana lingu-106kbit/isekhondi ukuya ku-848kbit/sec.Ngomakhalekhukhwini njengenkampani yenethiwekhi, isicelo sekhadi le-IC elingenakuthinta lihlanganiswa nomakhalekhukhwini, futhi izindlela ezintathu zokusetshenziswa zekhadi, umfundi kanye nephuzu lokukhomba zisetshenziselwa ukukhokha umakhalekhukhwini, uhlelo lokusebenza lwemboni, ukushintshana kwamaphuzu, amathikithi e-electronic. , ukuqashelwa kobunikazi, ukulwa nomgunyathi, ukukhangisa, njll.
I-RFID isho nje ukunamathisela isekethe ye-RFID equkethe ingxenye yefrikhwensi yomsakazo we-RFID kanye neluphu ye-antenna entweni.Ngemuva kokuthi into ephethe ithegi ye-RFID ingene endaweni ethile kazibuthe esethwe ngokuzenzakalelayo, izothumela isignali yefrikhwensi ethile, futhiUmfundi we-RFIDangathola ulwazi olubhalwe entweni ngaphambili.Lokhu kufana nebheji elilenga entanyeni yesisebenzi, futhi ungumphathi waso.Lapho engena emgqeni wakho wokubona, ungakwazi ukulazi igama lakhe, umsebenzi kanye nolunye ulwazi, futhi ungabhala kabusha okuqukethwe kwebheji lakhe.Uma i-RFID iwukuthi umuntu ufaka ibheji ukuze abanye bamqonde, khona-ke i-NFC iwukuthi abantu ababili bafaka amabheji, futhi bangakwazi ukushintsha ngokungenamthetho okuqukethwe ebhejini ngemva kokubonana, futhi bashintshe ulwazi olutholwe elinye iqembu.I-NFC ne-RFID zibukeka zifana ezingeni lomzimba, kodwa empeleni ziyizinkambu ezimbili ezihluke ngokuphelele, ngoba i-RFID empeleni iwubuchwepheshe bokuhlonza, kuyilapho i-NFC iwubuchwepheshe bokuxhumana.Umehluko othize ubonakala kulezi zici ezilandelayo
1. Imvamisa yokusebenza: Imvamisa ye-NFC igxilile kokuthi 13.56MHz, kuyilapho i-RFID ihlanganisa esebenzayo (2.4G, 5.8G), i-semi-active (125K, 13.56M, 915M, 2.4G, 5.8G), kanye ne-RFID esebenzayo.Okuvame kakhuluI-RFID yokwenziwa, engahlukaniswa ngamafrikhwensi aphansi (125KHz/134.2KHz), imvamisa ephezulu (13.56MHz) kanye nama-frequency aphezulu kakhulu (860-960) ngokuya ngefrikhwensi.
2. Imodi yokusebenza: I-NFC ihlanganisa isifundi sekhadi esingathintwanga muntu, ikhadi elingenakuthinta kanye nemisebenzi yontanga ibe yi-chip eyodwa, kuyilapho i-rfid kufanele ibe nomfundi nomaka.I-RFID ingabona kuphela ukufundwa nokwahlulela kolwazi, kuyilapho ubuchwepheshe be-NFC bugcizelela ukuxhumana kolwazi.I-NFC isekela kokubili imodi yokufunda-ukubhala kanye nemodi yekhadi;ku-RFID, isifundi sekhadi kanye nekhadi elingenakuthinta kuyizinto ezimbili ezizimele futhi azikwazi ukushintshwa.I-NFC isekela imodi ye-P2P, i-RFID ayisekeli imodi ye-P2P.
3. Ibanga lokusebenza: Ibanga lokusebenza le-NFC ngokwethiyori lingu-0 ~ 20cm, kodwa ekugcwalisekeni komkhiqizo, ngenxa yokusetshenziswa kobuchwepheshe bokucindezela okukhethekile, ibanga lokusebenza liyi-0 ~ 10cm kuphela, ukuze kuqinisekiswe kangcono ukuphepha. yebhizinisi;Njengoba i-RFID inamaza ahlukene, ibanga layo lokusebenza liyahluka ukusuka kumasentimitha ambalwa ukuya kwamashumi amamitha.
4. Iphrothokholi evamile: Iphrothokholi yokuxhumana eyisisekelo ye-NFC ihambisana nezinga lokuxhumana eliyisisekelo le-RFID yefrikhwensi ephezulu, okungukuthi, ehambisana nezinga le-ISO14443/ISO15693.Ubuchwepheshe be-NFC buphinde buchaze iphrothokholi enesendlalelo esiphezulu esiphelele uma kuqhathaniswa, njenge-LLP, NDEF ne-RTD, njll., kuyilapho umthetho olandelwayo we-RFID ungasekela i-ISO 11784&11785, ISO14443/ISO15693, kanye ne-EPC C1 GEN2/ISO 18000-6C namanye amazinga ngokuya amaza ahlukene.Nakuba ubuchwepheshe be-NFC ne-RFID buhlukile, ubuchwepheshe be-NFC, ikakhulukazi ubuchwepheshe bokuxhumana obuyisisekelo, buhambisana ngokugcwele nobuchwepheshe be-RFID obunamaza aphezulu.Ngakho-ke, emkhakheni wokufaka isicelo we-RFID ye-high-frequency, ubuchwepheshe be-NFC bungasetshenziswa.
5. Isiqondiso sesicelo: I-RFID isetshenziswa kakhulu emigqeni yokukhiqiza, ukugcinwa kwempahla, ukuphathwa kwempahla nezinye izinhlelo zokusebenza, kuyilapho i-NFC isebenza ekulawuleni ukufinyelela, amakhadi webhasi, ukukhokha ngeselula njll.
I-Shenzhen Handheld-Wireless Technology Co., Ltd.ihlanganisa i-R&D, ukukhiqiza, ukuthengisa kanye nesevisi yangemuva kokuthengisa.Ibilokhu igxile ekuhlinzekeni ngezifisoRFID hardware ephathwayokanye nezinsizakalo zesofthiwe zokuthutha, ukugcinwa kwempahla, ukudayisa, ukukhiqiza, ezokwelapha, ezempi kanye neminye imikhakha ukuze kuthuthukiswe intuthuko yonke yemboni ye-IOT iminyaka eminingi.
