Zvimiro zveRFID Technology

 

 

Tekinoroji yeRadio Frequency Identification (RFID), seyepamusoro-tekinoroji uye yekumisikidza ruzivo rwekukurumidza,{1}}nguva chaiyo, kuunganidza kwakaringana nekugadziriswa kweruzivo, yakarongwa seimwe yemhando gumi dzepamusoro dzakakosha dzemuzana remakore rechi21. RFID tekinoroji inoshandiswa zvakanyanya mumaindasitiri akasiyana sekugadzira, zvitoro, kutakura zvinhu, uye zvekufambisa nekupa yakasarudzika uye inoshanda identifier yezvinhu zvemuviri (kusanganisira zvinhu zvekutengesa, zvinhu zvemukati, midziyo, kutakura zvinhu, zvikamu zvekugadzira, nezvimwewo). RFID tekinoroji yave zvishoma nezvishoma yave yakakosha tekinoroji chishandiso uye nzira dzemabhizinesi kuvandudza zvinhu zvekutengesa cheni manejimendi, kuderedza mitengo, kuwana bhizinesi manejimendi ruzivo, kutora chikamu mukutenderera kwehupfumi hwenyika, uye kuwedzera kukwikwidza kwepakati. Kusimuka kweRFID tekinoroji hakusi nekuti tekinoroji nyowani, asi nekuti tekinoroji iyi yakura uye zvishoma nezvishoma yakawana kugona kuenda kune inoshanda yekushandisa.

 

 

RFID tekinoroji ndeye otomatiki yekuzivikanwa tekinoroji iyo yakabuda muma1990s. Inoshandisa magineti kana maelectromagnetic fields ku-kutaurirana ne{3}}nzira mbiri kuburikidza neredhiyo frequency kuzadzisa chinangwa chekuzivikanwa uye kuchinjanisa data. Inogona kuona-zvinhu zvinomhanya zvakanyanya uye panguva imwe chete kuziva zvakawanda zvinonangwa. Zvichienzaniswa nemaitiro echinyakare ekuzivikanwa, tekinoroji yeRFID inogona kupedzisa kuisa ruzivo uye kugadzirisa pasina kutarisana zvakananga, kuoneka kwemaziso, kana kupindira kwemanyorero, zvichiita kuti kushanda kuve nyore uye nekukurumidza. RFID tekinoroji inoshandiswa zvakanyanya mundima dzemaapplication dzinoda kuunganidzwa nekugadziriswa kwedata, sekugadzira, kutakura zvinhu, kutakurwa, kurapwa, anti-yekunyepera, kuronda, midziyo, uye kutonga midziyo, uye inoonekwa seyamangwana kutsiva mavara ebhakodhi. Kune nzira dzakasiyana-siyana dzekuzvizivisa otomatiki, imwe neimwe iine maitiro ayo uye ndima dzekushandisa, sezvakaratidzwa muTebhu 1-1.

 

 

Zvakanakira uye maficha eRFID otomatiki kuzivikanwa anonyanya kuratidzwa mune zvinotevera zvinhu.

 

Fast Scanning

Bhakodhi imwe chete inogona kuongororwa panguva; muverengi / munyori weRFID anogona panguva imwe chete kuziva uye kuverenga akawanda eRFID tag.

 

Miniaturization uye Diverse Shapes

RFID haina kudziviswa nehukuru uye chimiro panguva yekuverenga, uye haidi yakagadziriswa saizi yebepa uye mhando yekudhinda yekuverenga chokwadi. Uyezve, RFID tag inogona kuvandudzwa kuita miniaturized uye akasiyana mafomu ekushandisa kune akasiyana zvigadzirwa.

 

Anti-Kugona Kusvibisa uye Kusimba

Mutakuri wemabhakodhi echinyakare ipepa, rinosvibiswa zviri nyore, asi RFID ine kuramba kwakasimba kune zvinhu zvakaita seoiri nemakemikari. Uye zvakare, sezvo mabhakodhi akasungirirwa kumabhegi epurasitiki kana ekunze mabhokisi ekurongedza, iwo ari panjodzi yekukuvadzwa; RFID ma tag anochengeta data mune chip, nekudaro kudzivirira kukanganisa.

 

 

Reusability

Mabhakodhi akadhindwa pamabhegi epurasitiki kana ekunze ekurongedza mabhokisi haagone kuchinjwa mushure, nepo RFID tag inogona kudzokororwa kuwedzerwa, kugadziridzwa, uye kubviswa. Iyo data yakachengetwa mumatagi eRFID inofambisa ruzivo rwekuvandudza.

 

Permeability uye Barriers-Mahara Kuverenga

Kana yakavharwa, RFID inokwanisa kupinda-zvesimbi kana-zvinhu zvisingaoneki zvakadai sebepa, huni, nepurasitiki, uye kuita kutaurirana kunobaya mwoyo. Barcode scanner inogona kungoverenga mabarcode kana ari padhuze uye hapana chinovavharira.

 

Data Memory Capacity

Kukwana kwe-dimensional barcode i50B, uye -dimensional barcode (PDF417 barcode) inogona kuchengeta 1848 alphanumeric characters kana 2729 manhamba mavara, angangoita 500 mabhii ekuChina, ukuwo huwandu hweRFID hunogona kusvika mamegabytes akati wandei. Nekuvandudzwa kwevatakuri vendangariro, huwandu hwedata huri zvakare pane inogara ichiwedzera maitiro. Mune ramangwana, huwandu hwe data hunoda kutakura zvinhu huchawedzera, uye kudiwa kwesimba rinowedzera remabhii kuchawedzerawo zvinoenderana.

 

Chengetedzo

RFID inotakura ruzivo rwemagetsi, uye zvinyorwa zvayo zve data zvinogona kuchengetedzwa nemapassword, zvichiita kuti zviome kuumbwa kana kuchinjwa. Mumakore achangopfuura, RFID yakwezva vanhu vakawanda nekuda kwehunhu hwayo sekuti pedyo-kuverengwa kwenzvimbo uye kuchengetedza kwakakwirira. Izvo hazvingobatsiri mabhizinesi zvakanyanya kuvandudza kugona kwekutakura ruzivo manejimendi asi zvakare inogonesa kubatana kwekutengesa uye mabhizinesi ekugadzira, nekudaro kunyatsogamuchira ruzivo rwemhinduro, kudzora ruzivo rwekudiwa, uye optimization yese yekugovera cheni. Pane yakabatana yakajairika chikuva, RFID ma tag anogona kupa ruzivo rwekuyerera kwechigadzirwa chero nguva mune yese yekugovera cheni, ichipa chimwe nechimwe chigadzirwa ruzivo mutauro wakafanana wekutaurirana. Kuburikidza neinternet yekombuta, kuzivikanwa otomatiki uye kuchinjana ruzivo uye kugovana kwezvinhu zvinogona kuitika, zvichitungamira kune pachena manejimendi yezvinhu, kuwana chirevo chechokwadi che "Internet Yezvinhu".

 

 

Nhoroondo yeRFID inogona kurondedzerwa se "murwi wekare, kutarisa kutsva." RFID haisiriyo-tekinoroji itsva. Chikumbiro chayo chekutanga chakadzokera kuHondo Yenyika II (1940s), uko basa rayo panguva iyoyo raishandiswa kusiyanisa ndege dzevavengi kubva kundege dzinoshamwaridzana. Mukupera kwema1970, hurumende yeUS yakaendesa tekinoroji yeRFID kuchikamu chevanhu kuburikidza neLos Alamos Scientific Laboratory. Yekutanga kutengeserana kushandiswa kweRFID tekinoroji yaive pazvipfuyo. Mumakore ekuma1980, makambani akati wandei muUS neEurope akatanga kugadzira RFID tag. Parizvino, tekinoroji yeRFID yakashandiswa zvakanyanya munzvimbo dzakasiyana siyana, kubva pakutonga kwekuwana, manejimendi ezvipfuyo, kune manejimendi manejimendi, uye mitsetse yayo inogona kuonekwa kwese kwese. Nhoroondo yekuvandudza yeRFID tekinoroji inoratidzwa muTafura 1-1.

 

Tafura 1-1 RFID Technology Development History

 

Nguva	RFID Technology Development
1941-1950	Kuvandudzwa uye kushandiswa kweradar kwakasimudza tekinoroji yeRFID. Hwaro hwetekinoroji yeRFID tekinoroji yakaiswa muna 1948. Chikamu chekutanga chekuongorora cheRFID tekinoroji chaive zvakanyanya muchikamu chekuyedza murabhoritari.
1951-1960	RFID tekinoroji theory yakagadzirwa, uye kumwe kuedza kwekushandisa kwakatanga
1961-1970	RFID tekinoroji uye chigadzirwa R&D chaive munguva yekukura kukuru, uye akasiyana RFID tekinoroji yekuyedza yakakurumidza.
1971-1980	Mamwe ekutanga eRFID application akaoneka, RFID zvigadzirwa zvakapinda mubhizimusi rekunyorera nhanho, uye akasiyana akavharika masisitimu ekushandisa akatanga kubuda.
1981-1990	Iyo yekumisikidza yeRFID tekinoroji yakagamuchira kutariswa, uye zvigadzirwa zvakagamuchirwa zvakanyanya
1991-2000	Nyaya dzekumira dzakawedzera kusimbiswa, uye mhando dzezvigadzirwa zveRFID dzakapfuma
2001 kusvika ikozvino	Active electronic tags, passive electronic tags, uye semi{0}passive ma tags emagetsi zvese zvakagadziridzwa, uye mutengo wema tag emagetsi uri kuramba uchidzikira.

 

Kubva pamaonero ezvimiro, mushure memakore mazhinji ebudiriro, tekinoroji yeRFID iri pazasi 13.56MHz inenge yakura. Parizvino, tarisiro yeindasitiri iri pakati-ku{3}}yepamusoro-soro tekinoroji yeRFID, zvikuru-yemhando yeRFID tekinoroji mu860-960MHz (UHF bhendi), iri kusimudzira nekukurumidza. Nekudaro, iwo 2.45GHz uye 5.8GHz mabhendi achiri muchikamu chekuongorora chetsvagurudzo uye mashandisiro nekuda kwekusangana kwechigadzirwa, kukanganisa kukanganisa, uye tekinoroji yakaoma kunzwisisa.
