Ingcamango ye-NFC
Igama elipheleleyo le-NFC yiNear Field Communication, unxibelelwano olungenazingcingo olufutshane. I-NFC yiteknoloji engenazingcingo eyaqalwa yiPhilips yaza yakhuthazwa ngokudibeneyo yiNokia, iSony kunye nabanye abavelisi abadumileyo. I-NFC yaphuhliswa ngesiseko setekhnoloji yokuchongwa kwamaza erediyo angaqhagamshelaniyo (RFID) edityaniswe netekhnoloji yokunxibelelana engenazingcingo. Le teknoloji ekuqaleni iyindlela elula yokudibanisa Itekhnoloji yeRFIDkunye netekhnoloji yenethiwekhi, ngoku iguqukele ekubeni yitekhnoloji yonxibelelwano engenazingcingo yomgama omfutshane, kwaye indlela yayo yophuhliso ikhawuleza kakhulu.
Ingcamango yeRFID
I-RFID sisifinyezo se-Radio Frequency Identification, ekwaziwa ngokuba yi-electronic tag, eyiteknoloji yokuchonga ngokuzenzekelayo engenakuthintana. Ichonga ithagethi ethile ngemiqondiso yerediyo kwaye ifunda kwaye ibhale idatha efanelekileyo ngaphandle kokunxibelelana ngoomatshini okanye nge-optical nethagethi. Ayifuni ukungenelela ngesandla, ingasetyenziswa kwiindawo ezahlukeneyo ezinzima, inokuchonga izinto ezihamba ngesantya esiphezulu, inokuchonga iithegi ezininzi ngaxeshanye, kwaye umsebenzi ukhawuleza kwaye ulula.
Umahluko phakathi kwe-NFC kunye ne-RFID
Uluhlu lweeFrequency ezahlukeneyo
I-RFID yokusebenza rhoqo ibanzi. Ii-125KHZ kunye ne-133KHZ (i-frequency ephantsi), i-13.56MHZ (i-frequency ephezulu), i-900MHZ (i-frequency ephezulu kakhulu), 433MHZ, 2.4G, 5.8GMHZ (ubuninzi be-microwave). Ukongeza, i-UHF 900M ikwaligama eliqhelekileyo, alilo elichanekileyo. Ubuninzi bukwahluka ngokwamazwe ngamazwe. Umzekelo, ibhendi yefrikhwensi yaseYurophu (865.6MHZ-867.6MHZ), iSingapore (920MHz~925MHz), iTshayina (920.5MHZ-924.5MHZ okanye 840.5MHZ-844.5MHZ), iMelika (902M-928M), iBrazil (902M-907.5M okanye 915M-928M), njl.
Ireyithi yokusebenza ye-NFC yi-13.56MHZ kuphela. Singayiqonda ne-NFC njengesixhobo esincinci sobuchwepheshe be-RFID, esisebenzisa ibhendi ye-13.56MHz yibhendi ethile yereyithi ye-HF RFID. Ukusetyenziswa kwale bhendi yereyithi kuthandwa kakhulu, kwaye kubandakanya iintlobo ngeentlobo zeeprotokholi. Kodwa i-13.56MHZ ayithethi ukuba yonke ilingana ne-NFC.
Umgama owahlukileyo woThumelo
Ngenxa yokuba i-RFID inobude bexesha lokusebenza obukhulu, umgama wokudluliselwa kwiifrikhwensi ezahlukeneyo nawo wahlukile. Omfutshane ziisentimitha ezimbalwa, kwaye ode unokufikelela kwiimitha ezininzi okanye amashumi eemitha.
I-NFC yiteknoloji yonxibelelwano yomgama omfutshane. Njengoko igama lisitsho, uluhlu lokudlulisela lufutshane, ludla ngokuba ngaphakathi kwe-20cm, ukuze unxibelelwano lube lukhuselekile. Oku kungenxa yeteknoloji ekhethekileyo yokunciphisa isignali eyamkelwe yi-NFC, eneempawu zomgama omfutshane, i-bandwidth ephezulu kunye nokusetyenziswa kwamandla aphantsi.
Itekhnoloji yoNxibelelwano eyahlukeneyo
Yonke inkqubo yonxibelelwano ye-RFID yenziweIithegi zeRFID, ii-antenna kunye nee-RFID readers, zonke eziyimfuneko. Inkqubo kufuneka ifunde kwaye igwebe ulwazi lwethegi ngokulandelelana komfundi.
I-NFC idibanisa imisebenzi yokufunda, ikhadi elingenaqhagamshelwano kunye nemisebenzi yenqaku ukuya kwinqanaba kwitshiphu enye, kwaye iifowuni ezimbini eziphathwayo okanye izixhobo ezinokunxitywa ezinolawulo lwe-NFC olwakhelwe ngaphakathi zinokwenza unxibelelwano lolwazi lusebenze kufutshane. Umahluko kwitekhnoloji yonxibelelwano lolona mahluko mkhulu phakathi kwezi zimbini. I-NFC yindlela yonxibelelwano yabucala yomgama omfutshane.
Olu mahluko lukwakhokelela kumahluko kwizicelo zawo. Ngokwembono yeemeko zesicelo, kunokubonwa ukuba kukho umahluko ocacileyo phakathi kweRFID kunye neNFC. I-RFID igxile kwizinto ezithile, ngelixa i-NFC igxile kumsebenzisi kwaye ifuna ukubandakanyeka kwabasebenzisi ukuze kufezekiswe imisebenzi. I-RFID iqonda ukufundwa nokugweba ulwazi, ngelixa itekhnoloji ye-NFC igxininisa ukusebenzisana kolwazi ngokuguquguquka ngakumbi kunye nokubhekisa kwicala elinye.
Kwiindlela ezisebenzayo, i-RFID inokwenza umfundi akwazi ukufunda inani elikhulu lee-RFIDIilebheli zeRFIDkwangaxeshanye, into exhaphake kakhulu kwimpahla yokugcina impahla. I-RFID idla ngokusetyenziswa kwiimpahla zothutho, ukuthengisa, ukuhamba ngenqwelomoya, ezonyango, ulawulo lweempahla. Amakhadi e-ID esizukulwana sesibini kunye namatikiti eOlimpiki aseBeijing onke ane-akhayinti eyakhelwe ngaphakathi.Iitships zeRFID, kwaye inkqubo ye-ETC ye-elektroniki yokuqokelelwa kwerhafu engamiyo kwindlela enkulu ikwasebenzisa itekhnoloji ye-RFID.
I-NFC idla ngokuba yeyomntu ngamnye, kwaye uluhlu lokudluliselwa kwe-NFC luncinci kakhulu kunolwe-RFID. Ke ngoko, i-NFC idlala indima enkulu kwicandelo lolawulo lokufikelela, uthutho lukawonke-wonke, kunye nentlawulo yeselula.
Enyanisweni, imeko yesicelo seRFID ibanzi kakhulu kuneNFC, kwaye kunokuthiwa iRFID ineNFC. Nangona kunjalo, ngenxa yokwahluka kweempawu zokusebenza phakathi kweRFID kunye neNFC, ezi zimbini azibangeli ubudlelwane bokhuphiswano, kodwa zidlala indima kwiimeko zazo ezihlengahlengisiweyo. Nokuba kusetyenziswa luphi na ubuchwepheshe, umceli mngeni omkhulu uhlala ucinge ngendlela yokuphucula amava omsebenzisi kunye nokuzisa lula kubasebenzisi.
