Umqondo we-NFC
Igama eliphelele le-NFC yi-Near Field Communication, ukuxhumana okungenantambo okufushane. I-NFC ubuchwepheshe obungenantambo obuqalwe yiPhilips futhi obukhuthazwa ngokubambisana yiNokia, iSony kanye nabanye abakhiqizi abadumile. I-NFC yathuthukiswa ngesisekelo sobuchwepheshe bokuhlonza imvamisa yomsakazo (RFID) obungaxhumani buhlanganiswe nobuchwepheshe bokuxhumana okungenantambo. Lobu buchwepheshe ekuqaleni buwukuhlanganiswa okulula kwe Ubuchwepheshe be-RFIDkanye nobuchwepheshe benethiwekhi, manje sekuguqukele ekubeni ubuchwepheshe bokuxhumana obungenantambo obufushane, futhi ukuthambekela kwayo kokuthuthuka kuyashesha impela.
Umqondo we-RFID
I-RFID isifinyezo se-Radio Frequency Identification, eyaziwa nangokuthi i-electronic tag, okuwubuchwepheshe bokuhlonza okuzenzakalelayo obungenakuthinta. Ihlonza ithagethi ethile ngamasignali omsakazo futhi ifunde futhi ibhale idatha efanele ngaphandle kokuthintana ngomshini noma ngokubona nethagethi. Ayidingi ukungenelela ngesandla, ingasetshenziswa ezindaweni ezahlukahlukene ezinzima, ingahlonza izinto ezihamba ngesivinini esikhulu, ingahlonza amathegi amaningi ngesikhathi esisodwa, futhi ukusebenza kuyashesha futhi kulula.
Umehluko phakathi kwe-NFC ne-RFID
Ibanga Elihlukile Lokuvama
Imvamisa yokusebenza ye-RFID ibanzi kakhulu. Ngokuvamile kusetshenziswa i-125KHZ kanye ne-133KHZ (imvamisa ephansi), i-13.56MHZ (imvamisa ephezulu), i-900MHZ (imvamisa ephezulu kakhulu), 433MHZ, 2.4G, 5.8GMHZ (imvamisa ye-microwave). Ngaphezu kwalokho, i-UHF 900M nayo iyigama elijwayelekile, hhayi eliqondile. Imvamisa nayo iyahlukahluka kuye ngezwe. Isibonelo, ibhendi yemvamisa yaseYurophu (865.6MHZ-867.6MHZ), iSingapore (920MHz~925MHz), iShayina (920.5MHZ-924.5MHZ noma 840.5MHZ-844.5MHZ), i-United States (902M-928M), iBrazil (902M-907.5M noma 915M-928M), njll.
Imvamisa yokusebenza ye-NFC ingu-13.56MHZ kuphela. Singaqonda ngisho ne-NFC njengeqembu elincane lobuchwepheshe be-RFID, elisebenzisa ibhendi ye-13.56MHz eliyibhendi yemvamisa ethile ye-HF RFID. Ukusetshenziswa kwale bhendi yemvamisa kuthandwa kakhulu, futhi kuhilela izinhlobo ezahlukene zezinqubo. Kodwa i-13.56MHZ akusho ukuthi konke kufana ne-NFC.
Ibanga Elihlukile Lokudlulisa
Ngenxa yokuthi i-RFID inobubanzi obukhulu bokusebenza kwemvamisa, ibanga lokudlulisa kumaza ahlukene nalo lihlukile. Elifushane lingamasentimitha ambalwa, kanti elide lingafinyelela amamitha amaningana noma ngisho namashumi amamitha.
I-NFC ubuchwepheshe bokuxhumana obusebenzisa ibanga elifushane. Njengoba igama lisho, ibanga lokudlulisa lifushane kakhulu, ngokuvamile lingaphakathi kwamasentimitha angama-20, ukuze ukuxhumana kube okuphephile. Lokhu kungenxa kakhulu yobuchwepheshe obuhlukile bokunciphisa isignali obusetshenziswa yi-NFC, obunezici zebanga elifushane, i-bandwidth ephezulu kanye nokusetshenziswa kwamandla okuphansi.
Ubuchwepheshe Obuhlukene Bokuxhumana
Lonke uhlelo lokuxhumana lwe-RFID luquketheAmathegi e-RFID, ama-antenna kanye nabafundi be-RFID, konke okubalulekile. Uhlelo ludinga ukufunda nokwahlulela ulwazi lwethegi ngokungaqondile ngomfundi.
I-NFC ihlanganisa imisebenzi yokufunda, ikhadi elingenakuthinta kanye nemisebenzi yokukhomba iphuzu ibe yi-chip eyodwa, futhi omakhalekhukhwini ababili noma amadivayisi agqokwayo anokulawula kwe-NFC okwakhelwe ngaphakathi angenza ukuxhumana kolwazi kube seduze. Umehluko kubuchwepheshe bokuxhumana umehluko omkhulu phakathi kwalokhu okubili. I-NFC iyindlela yokuxhumana yangasese ekude.
Lokhu kwehluka kuholela nasekuhlukeni kwezinhlelo zokusebenza zazo. Ngokombono wezimo zohlelo lokusebenza, kungabonakala ukuthi kukhona ukwehluka okusobala phakathi kwe-RFID ne-NFC. I-RFID igxile ezintweni, kuyilapho i-NFC igxile kumsebenzisi futhi idinga ukuhlanganyela kwabasebenzisi ukuze kufezwe imisebenzi. I-RFID iqaphela ukufundwa nokwahlulelwa kolwazi, kuyilapho ubuchwepheshe be-NFC bugcizelela ukusebenzisana kolwazi ngokuguquguqukayo kakhudlwana nangokuqondana okubili.
Ezinhlelweni ezisebenzayo, i-RFID ingenza umfundi akwazi ukufunda inani elikhulu lezintoAmalebula e-RFIDngesikhathi esifanayo, okuyinto evame kakhulu ekugcinweni kwempahla. I-RFID ivame ukusetshenziswa kwezokuthutha, ezitolo, ezindizeni, kwezokwelapha, nasekuphathweni kwempahla. Amakhadi omazisi esizukulwane sesibili kanye namathikithi e-Olimpiki aseBeijing wonke anama-akhiwo akhelwe ngaphakathi.Ama-RFID chips, kanye nohlelo lwe-ETC lwe-electronic non-stop toll oluku-expressway nalo lusebenzisa ubuchwepheshe be-RFID.
I-NFC ngokuvamile idluliselwa kumuntu nomuntu, futhi ububanzi bokudluliswa kwe-NFC buncane kakhulu kune-RFID. Ngakho-ke, i-NFC idlala indima enkulu emikhakheni yokulawula ukufinyelela, ezokuthutha zomphakathi, kanye nokukhokha ngeselula.
Eqinisweni, isimo sesicelo se-RFID sibanzi kakhulu kune-NFC, futhi kungashiwo nokuthi i-RFID iqukethe i-NFC. Kodwa-ke, ngenxa yokwehluka kwezici zokusebenza phakathi kwe-RFID ne-NFC, lokhu kokubili akulona ubudlelwano bokuncintisana, kodwa kudlala indima ezimweni zazo eziguquliwe. Kungakhathaliseki ukuthi kusetshenziswa luphi ubuchwepheshe, inselele enkulu ivame ukucabanga ngendlela yokuthuthukisa ulwazi lomsebenzisi nokuletha ukusebenziseka kwangempela kubasebenzisi.
