RFID (Radio Frequency Identification), musimboti wayo ndeyekusingabatanidzi data kutaurirana pakati pemuverengi uye teki kuzadzisa chinangwa chekuzivisa chinangwa.Chero bedzi iri redhiyo frequency nzira, uye inogona kuzivikanwa nenzira iyi, inoverengerwa sechikamu cheRFID.Zvinoenderana neiyo frequency, inogona kazhinji kukamurwa kuita yakaderera frequency, yakakwira frequency, Ultra-yakakwira frequency, 2.4G zvichingodaro.RFID inoshandiswa zvakanyanya, neyakajairwa maapplication anosanganisira manejimendi emhuka, manejimendi emotokari, mutsara wekugadzira otomatiki, manejimendi easset, manejimendi evashandi, uye smart kurapwa.
NFC (Near Field Communication) tekinoroji yakatanga gare gare kupfuura RFID.Yakanga iri yenguva pfupi-yewaya yekutaurirana tekinoroji yakanyanya kusimudzirwa nePhilips, Nokia neSony makore akapoteredza 2003. Inzira yechinhambwe isingabatane.Iyo yekushanda frequency ndeye 13.56MHz, uye mwero wekutaurirana ndeye 106kbit/sec kusvika 848kbit/sec.Kuburikidza nenharembozha semutakuri, iyo isingabatanidzi IC kadhi application inosanganiswa nenharembozha, uye matatu ekushandisa modhi yekadhi, muverengi uye point-to-point anoshandiswa kuona kubhadhara nhare, indasitiri application, poindi exchange, electronic ticketing. , kuzivikanwa kwekuzivikanwa, anti-yekunyepedzera, kushambadza, nezvimwe.
RFID inongoreva kubatanidza RFID wedunhu ine RFID radio frequency chikamu uye antenna loop kune chimwe chinhu.Mushure mekunge chinhu chakatakura iyo RFID tag yapinda mune chaiyo magineti yakaiswa zvisirizvo, inotumira chiratidzo cheiyo frequency, uye iyoRFID muverengianogona kuwana ruzivo rwakanyorwa pane chinhu kare.Izvi zvakangofanana nebheji rakarembera pamutsipa wemushandi, uye ndiwe mutariri wake.Paanopinda mumutsara wako wekuona, unogona kuziva zita rake, basa uye rumwe ruzivo, uye unogona kunyora zvakare zviri mubheji rake.Kana RFID iri kuti munhu anopfeka bheji kuitira kuti vamwe vamunzwisise, ipapo NFC ndeyokuti vanhu vaviri vanopfeka mabheji, uye vanogona kushandura zvisiri izvo zviri pabheji mushure mokunge vaonana, uye shandura ruzivo rwakagamuchirwa nerimwe bato.NFC neRFID zvinotaridzika zvakafanana padanho remuviri, asi iwo ari maviri akasiyana minda, nekuti RFID inonyanya kuzivikanwa tekinoroji, nepo NFC iri tekinoroji yekutaurirana.Misiyano chaiyo inoratidzwa muzvikamu zvinotevera
1. Kushanda nguva yakawanda: NFC frequency inogadziriswa pa13.56MHz, nepo RFID inosanganisira inoshanda (2.4G, 5.8G), semi-active (125K, 13.56M, 915M, 2.4G, 5.8G), uye passive RFID.Inonyanya kuzivikanwa ndeyepassive RFID, iyo inogona kupatsanurwa kuita yakaderera frequency (125KHz / 134.2KHz), yakakwirira frequency (13.56MHz) uye yekupedzisira-yakakwirira frequency (860-960) frequency mabhendi zvichienderana nekuwanda.
2. Maitiro ekushanda: NFC inobatanidza muverengi wekadhi asingabatanidzi, kadhi risina kubata uye peer-to-peer mabasa mune imwe chip, nepo rfid inofanira kuva nemuverengi uye tag.RFID inogona chete kuona kuverenga uye kutonga kweruzivo, nepo NFC tekinoroji ichisimbisa kufambidzana kweruzivo.NFC inotsigira zvese kuverenga-kunyora maitiro uye kadhi modhi;muRFID, muverengi wekadhi uye kadhi risingabatike masangano maviri akazvimirira uye haagone kuchinjika.NFC inotsigira P2P modhi, RFID haitsigire P2P maitiro.
3. Kushanda kureba: Kushanda kureba kweNFC kunoti 0 ~ 20cm, asi mukuzadzikiswa kwechigadzirwa, nekuda kwekushandiswa kwehunyanzvi hwekudzvanya tekinoroji, kureba kwekushanda kunongova 0 ~ 10cm, kuitira kuti kuve nechokwadi chekuchengetedzwa. zvebhizimisi;Sezvo RFID iine ma frequency akasiyana, kureba kwayo kwekushanda kunosiyana kubva pamasendimita mashoma kusvika kumakumi emamita.
4. Standard protocol: Iri pasi pechirongwa chekukurukurirana cheNFC chinopindirana netsika yekukurukurirana kwepamusoro-frequency RFID, kureva, inowirirana ne ISO14443 / ISO15693 standard.NFC tekinoroji inotsanangudzawo yakanyatsokwana yekumusoro-layer protocol, senge LLCP, NDEF uye RTD, nezvimwewo, nepo RFID protocol inogona kutsigira ISO 11784&11785, ISO14443/ISO15693, uye EPC C1 GEN2/ISO 18000-6C uye mamwe mazinga zvinoenderana ne ma frequency akasiyana.Kunyangwe tekinoroji yeNFC neRFID dzakasiyana, tekinoroji yeNFC, kunyanya tekinoroji yekukurukurirana, inofambirana zvizere nehunyanzvi hweRFID hwepamusoro.Naizvozvo, mumunda wekushandisa wepamusoro-frequency RFID, NFC tekinoroji inogona kushandiswa zvakare.
5. Maitiro ekushandisa: RFID inonyanya kushandiswa mumitsara yekugadzira, warehousing logistics, asset management uye mamwe maapplication, nepo NFC inoshanda mukutonga kwekuwana, makadhi ebhazi, kubhadhara nhare nezvimwe.
Shenzhen Handheld-Wireless Technology Co., Ltd.inobatanidza R&D, kugadzira, kutengesa uye mushure mekutengesa sevhisi.Yakanga ichitarisa pakupa zvakagadzirirwaRFID handheld hardwareuye masevhisi esoftware ekugadzirisa zvinhu, kuchengetedza, zvitoro, kugadzira, zvekurapa, zvechiuto uye mamwe minda kusimudzira kusimudzira kwese kweIOT indasitiri kwemakore mazhinji.
