Pfungwa yeNFC
Zita rakazara reNFC ndere Near Field Communication, pfupi-renji isina waya yekutaurirana. NFC tekinoroji isina waya yakatangwa naPhilips uye yakasimudzirwa pamwe chete neNokia, Sony nevamwe vagadziri vane mukurumbira. NFC inogadzirwa pahwaro hwekusaonana neredhiyo frequency identification (RFID) tekinoroji yakasanganiswa newaya yekubatanidza tekinoroji. Iyi tekinoroji pakutanga ingori nyore kubatanidza kweRFID tekinorojiuye tekinoroji yetiweki, ikozvino yashanduka kuita ipfupi-renji isina waya yekutaurirana tekinoroji, uye maitiro ayo ekusimudzira anokurumidza.
Pfungwa yeRFID
RFID ndiyo chidimbu cheRadio Frequency Identification, inozivikanwawo semagetsi tag, inova tekinoroji isingabatanidzi yekuzivisa tekinoroji. Inotaridza yakanangana neredhiyo masaini uye inoverenga uye inonyora yakakodzera data pasina mechaniki kana yekuona kuonana neicho chinangwa. Izvo hazvidi kupindira kwemaoko, zvinogona kushandiswa munzvimbo dzakasiyana-siyana dzakaoma, zvinogona kuona zvinhu zvinomhanya zvakanyanya, zvinogona kuona ma tag akawanda panguva imwe chete, uye kushanda kunokurumidza uye nyore.
Musiyano uripo pakati peNFC neRFID
Different Frequency Range
RFID inoshanda frequency yakakura. Inowanzo shandiswa ndeye 125KHZ uye 133KHZ (yakaderera frequency), 13.56MHZ (yakakwirira frequency), 900MHZ (ultra-high frequency ), 433MHZ, 2.4G, 5.8GMHZ (microwave frequency). Pamusoro pezvo, UHF 900M zvakare iri izwi rakajairwa, kwete chairo. Frequency zvakare inosiyana munyika nenyika. Semuenzaniso, European frequency band (865.6MHZ-867.6MHZ), Singapore (920MHz~925MHz), China (920.5MHZ-924.5MHZ kana 840.5MHZ-844.5MHZ), United States (902M-928M), Brazil (902M-928M), Brazil (902M-928M). 907.5M kana 915M- 928M), nezvimwewo.
Iyo yekushanda frequency yeNFC ingori 13.56MHZ. Tinogona kutonzwisisa NFC sechikamu cheRFID tekinoroji, inoshandisa iyo 13.56MHz bhendi ndiyo chaiyo frequency bhendi yeHF RFID. Iko kushandiswa kweiyi frequency bhendi kwakakurumbira kwazvo, uye kunosanganisira akasiyana maprotocol. Asi 13.56MHZ hazvireve kuti zvese zvakaenzana neNFC.
Different Transmission Distance
Nekuti RFID ine hombe yekushanda frequency span, kureba kwekufambisa pama frequency akasiyana kwakasiyanawo. Iyo ipfupi masendimita mashoma, uye iyo yakareba inogona kusvika pamamita akati wandei kana makumi emamita.
NFC tekinoroji yekutaurirana kure kure. Sezvinoratidzwa nezita racho, huwandu hwekutumira hupfupi, kazhinji mukati me20cm, kuitira kuti kutaurirana kuve kwakachengeteka. Izvi zvinonyanya kukonzerwa neiyo yakasarudzika chiratidzo chekudzivirira tekinoroji yakagamuchirwa neNFC, ine hunhu hwechinhambwe chipfupi, bandwidth yakakwira uye yakaderera simba rekushandisa.
Yakasiyana Communication Technology
Iyo yese RFID yekutaurirana system ineRFID tags , antennas uye vaverengi veRFID, zvese izvo zvakakosha. Iyo sisitimu inoda kuverenga uye kutonga iyo tag ruzivo unidirectionally kuburikidza nemuverengi.
NFC inosanganisa muverengi, isingabatike kadhi uye inonongedza-inongedzo mabasa mune imwechete chip, uye nhare mbozha mbiri kana midziyo inopfekwa ine yakavakirwa-mukati NFC control inogona kuona kupindirana kweruzivo padhuze. Musiyano wehunyanzvi hwekutaurirana ndiwo musiyano mukuru pakati pezviviri izvi. NFC inzira ipfupi yekutaurirana yakavanzika.
Misiyano iyi inotungamirawo kune misiyano mumashandisirwo awo. Kubva pamaonero emamiriro ekushandisa, zvinogona kuoneka kuti pane misiyano iri pachena pakati peRFID neNFC. RFID chinhu-pakati, nepo NFC iri mushandisi-pakati uye inoda kutora mukana kwevashandisi kuita mabasa. RFID inoona kuverenga uye kutonga kweruzivo, nepo tekinoroji yeNFC ichisimbisa kudyidzana kweruzivo neinochinjika uye bi-directional.
Mukushandisa zvinoshanda, RFID inogona kugonesa muverengi kuverenga nhamba huru yeRFID mavara panguva imwecheteyo, iyo inonyanya kuwanda mudura rekuchengetedza. RFID inowanzo shandiswa mukutakura zvinhu, zvitoro, ndege, kurapwa, manejimendi. Iwo echipiri-chizvarwa ID makadhi uye Beijing Olympic matikiti ose akavaka-mukatiRFID chips, uye ETC electronic non-stop toll collection system panzira inofambisa inoshandisawo RFID tekinoroji.
NFC inowanzova imwe-kune-imwe, uye huwandu hwekutapurirana hweNFC hudiki zvakanyanya pane hweRFID. Naizvozvo, NFC inoita basa rakakura muminda yekutonga kwekuwana, zvifambiso zvevoruzhinji, uye kubhadhara nhare.
Asi izvo, RFID's application mamiriro akafara kwazvo kupfuura NFC, uye zvinogona kutaurwa kuti RFID ine NFC. Nekudaro, nekuda kwekusiyana kwemaitiro anoshanda pakati peRFID neNFC, zviviri izvi hazviumbe hukama hwemakwikwi, asi vanoita basa mune yavo yakagadziridzwa mamiriro. Hazvina mhosva kuti tekinoroji inoshandiswa sei, dambudziko rakakura nderekufunga nezve nzira yekuvandudza ruzivo rwemushandisi uye kuunza kurerukirwa chaiko kune vashandisi.
