Pfungwa yeNFC
Zita rakazara reNFC nderekuti Near Field Communication, kutaurirana kusina waya kwenguva pfupi. NFC itekinoroji isina waya yakatangwa nePhilips uye yakasimudzirwa pamwe chete neNokia, Sony nevamwe vagadziri vane mukurumbira. NFC yakagadzirwa zvichibva patekinoroji yekuziva mafrequency eredhiyo isina kubatana (RFID) yakasanganiswa netekinoroji yekubatanidza isina waya. Pakutanga iyi tekinoroji ingori kubatanidzwa kuri nyore kwe Tekinoroji yeRFIDuye tekinoroji yenetiweki, ikozvino yashanduka kuita tekinoroji yekutaurirana isina waya yekukurumidza, uye kufambira mberi kwayo kuri kukurumidza.
Pfungwa yeRFID
RFID ipfupiso yeRadio Frequency Identification, inozivikanwawo se electronic tag, inova tekinoroji yekuziva otomatiki isina kubata. Inoona chinangwa chaicho kuburikidza nemasaini eredhiyo uye inoverenga nekunyora data rakakodzera pasina kusangana nechinhu chacho nechinhu chacho. Haidi kupindira nemaoko, inogona kushandiswa munzvimbo dzakasiyana-siyana dzakaoma, inogona kuona zvinhu zvinofamba nekukurumidza, inogona kuona ma tag akawanda panguva imwe chete, uye mashandiro acho anokurumidza uye ari nyore.
Musiyano uripo pakati peNFC neRFID
Mhando dzakasiyana dzeFrequency
Mafrequency ekushanda eRFID akafara. 125KHZ ne133KHZ (frequency yakaderera), 13.56MHZ (frequency yakakwirira), 900MHZ (kakawanda zvakanyanya), 433MHZ, 2.4G, 5.8GMHZ (ma microwave frequency). Pamusoro pezvo, UHF 900M izwi rekuti "general", kwete rakanyatsojeka. Ma frequency anosiyanawo kubva kunyika kuenda kunyika. Semuenzaniso, bhendi reEuropean frequency (865.6MHZ-867.6MHZ), Singapore (920MHz~925MHz), China (920.5MHZ-924.5MHZ kana 840.5MHZ-844.5MHZ), United States (902M-928M), Brazil (902M-907.5M kana 915M-928M), nezvimwewo.
Mafambiro ekushanda kweNFC i13.56MHZ chete. Tinogona kutonzwisisa NFC sechikamu cheRFID tekinoroji, iyo inoshandisa 13.56MHz band ndiyo chaiyo frequency band yeHF RFID. Kushandiswa kwefrequency band iyi kwakakurumbira zvikuru, uye kunosanganisira maprotocol akasiyana-siyana. Asi 13.56MHZ hazvirevi kuti zvese zvakaenzana neNFC.
Kureba kwakasiyana kwekutumira
Nekuti RFID ine nguva yakakura yekushanda, daro rekutumirwa kwemafrequencies akasiyana rakasiyanawo. Ripfupi masendimita mashoma, uye refu rinogona kusvika mamita akati wandei kana kutosvika makumi emamita.
NFC inyanzvi yekutaurirana iri kure kure. Sezvinoratidzwa nezita racho, huwandu hwekutumira hupfupi, kazhinji huri mukati me20cm, saka kutaurirana kwacho kuchava kwakachengeteka. Izvi zvinonyanya kukonzerwa nehunyanzvi hwakasiyana hwekudzivirira masaini hwakashandiswa neNFC, hune hunhu hwekufamba kure kure, bandwidth yakakwira uye kushandiswa kwesimba shoma.
Tekinoroji Yekutaurirana Yakasiyana
Sisitimu yese yekutaurirana yeRFID ineMa tag eRFID, maantenna nemaRFID reader, zvese izvi hazvidikanwi. Sisitimu iyi inofanira kuverenga nekuongorora ruzivo rwetag nenzira imwe chete kuburikidza nemuverengi.
NFC inobatanidza mashandiro ekuverenga, emakadhi asingabatanidzi uye epoinzi kuita chip imwe chete, uye nharembozha mbiri kana zvishandiso zvinopfekwa zvine NFC control yakavakirwa mukati zvinogona kuita kuti ruzivo rushande zviri pedyo. Musiyano uripo muhunyanzvi hwekutaurirana ndiwo musiyano mukuru pakati pezviviri izvi. NFC inzira yekutaurirana yega iri kure.
Kusiyana uku kunotungamirawo mukusiyana mumashandisirwo azvo. Kubva pamaonero emamiriro ekushandisa, zvinogona kuonekwa kuti pane musiyano uri pachena pakati peRFID neNFC. RFID inotarisa zvinhu, nepo NFC inotarisa mushandisi uye inoda kuti vashandisi vatore chikamu kuti vawane mabasa. RFID inoita kuti ruzivo ruve nyore kuverenga nekusarudza, nepo tekinoroji yeNFC ichisimbisa kudyidzana kwemashoko nerunochinjika uye rwunotenderera kumativi maviri.
Mumashandisirwo anoshanda, RFID inogona kugonesa muverengi kuverenga akawandaMazita eRFIDpanguva imwe chete, izvo zvinonyanya kuwanikwa muzvinhu zviri mudura. RFID inowanzo shandiswa muzvinhu zvinotakura zvinhu, zvitoro, ndege, zvekurapa, manejimendi yemidziyo. Makadhi eID echizvarwa chechipiri uye matikiti eOlympic eBeijing ese ane zvinhu zvakavakirwa mukati.machipisi eRFID, uye sisitimu yeETC yemagetsi isingamire yekuunganidza mari yekufambisa pamugwagwa mukuru inoshandisawo tekinoroji yeRFID.
NFC inowanzo shandiswa nemunhu mumwe chete, uye huwandu hwekutumira kweNFC hudiki zvikuru pane hweRFID. Saka, NFC ine basa guru muminda yekudzora kupinda, kutakurwa kwevanhu, uye kubhadhara nefoni.
Kutaura zvazviri, mamiriro ekushandiswa kweRFID akakura kupfuura NFC, uye zvinogona kutaurwa kuti RFID ine NFC. Zvisinei, nekuda kwekusiyana kwehunhu hwekushanda pakati peRFID neNFC, zviviri izvi hazviumbi hukama hwemakwikwi, asi zvine basa muzviitiko zvavo zvakagadziriswa. Pasinei nekushandiswa kwetekinoroji ipi, dambudziko guru rinowanzo funga nezvekuti ungavandudza sei ruzivo rwemushandisi uye kuunza nyore kune vashandisi.
