Indaleko ye-rfid

Igama elipheleleyo le-RFID luchonga irediyo. Itekhnoloji yoNxibelelwano engenazingcingo kunye nohlobo lwetekhnoloji yokuqonda ngokuzenzekelayo. Inkqubo ye-RFID sisixhobo se-Hardware esekwe kwitekhnoloji ye-RFID, esebenzisa irediyo ye-wireless wireless ye-widirecancy ye - Unxibelelwano lwedatha yoqhakamshelwano. Isebenzisa irediyo yerediyo engenazingcingo yokufunda nokubhala imithombo yeendaba erekhodiweyo (iithegi ze-elektroniki okanye amakhadi e-rf), emva koko izuze injongo yokuchonga iithagethi kunye nokutshintsha idatha. Ithathelwa ingqalelo enye yezona teknoloji ezithembisayo zeTekhnoloji yenkulungwane yama-21.

 

Ngo-1935, uSir Robert Watson Watt watt off fumancking kwaye wafumana i-rang (i-radar), enokuthathwa njengemvelaphi ye-RFID. Itekhnoloji ye-RFID yangoku ivele ukusuka ngo-1940 ukuya ku-1950 kwaye yaqala yasetyenziswa kwiMfazwe yesibini yeHlabathi. Iitekhnoloji ezifanayo zazisetyenziswa ngu-Allies kunye neJamani yokuchonga utshaba kunye nenqwelomoya. UCharles Walton wayila i-RFID ye-RFID ephathekayo ngo-1973, ukuba ngumnini we-RFID. Iindleko eziphezulu zokuqala ze-rfid zithintele kakhulu isicelo sayo sorhwebo. Ngokuphuhliswa kwetekhnoloji, iindleko ze-Hardware ziye zancipha, kwaye kwakungekho kude kube ngo-1980 kangangokuba yaqala ukuba nentengiso. Emva kweminyaka emininzi yokuphucula okuqhubekayo, njengophando ngokunciphisa i-RFID, ukuba itekhnoloji iqhubeke iphuculwe. Izixhobo zeHardware zinciphisa iindleko. Ngo-2003, iUnited States yazisa umgangatho wokuqala werediyo frequency, kwaye ngoku iindleko zemveliso ezinxulumene noko ziye zancipha, kwaye amabala eefowuni anyukile ngokuthe ngcembe kwaye achume.

 

Umgaqo wokuSebenza we-RFID

Okokuqala, kufuneka sazi ukuba inkqubo epheleleyo ye-RFId iqulethe iinxalenye ezintathu: umfundi, ithegi ye-elektroniki, kunye nenkqubo yolawulo lwedatha. Umgaqo wayo wokuSebenza kukuba ithegi ingena kwindawo yokufunda yomfundi, kwaye umfundi ukhupha isantya esithile samandla erediyo, esetyenziswa yisekethe yokuqhuba i-tag ukuthumela idatha yangaphakathi. Ngeli xesha, umfundi ngokulandela kwaye echaza idatha, kwaye ayithumele kwisicelo sokuqinisekiswa okuhambelanayo.

 

Ukuba i-RFID ihlelwa ngokwendlela yokuhambisa amandla, inokwahlulwa ibe yi-RFID esebenzayo, i-rfid esebenzayo, kunye ne-SEID RFID.

I-1. I-Priveve rfid

Phakathi kwezi ntlobo ze-RFID, i-RFID ye-RFID eneempawu zokuqala kwaye ibonakale kakhulu, kwaye isicelo sayo sikwaninzi kakhulu. Ungatsho ukuba yinkqubo ye-RFID ye-RFID. Ngaba i-RFID ingenayo inomthombo wamandla, angathini ukuwanika amandla? Ngapha koko, kukufumana imiqondiso ye microwave edluliselwe ngabafundi be-RFID kunye nokufumana amandla ngekholeji ye-elektromagnetic ye-electromagnetic enokusetyenziswa ngokufutshane amandla, ngaloo ndlela begqiba inkqubo yokutshintshiselana ngolwazi. Ukongeza, i-frequency yomsebenzi wakhe ikakhulu ikwi-125kzz, i-13.53mhz, njl njl, kwaye sihlala sisebenzisa olu hlobo lwekhadi lebhasi, kunye nekhadi le-Cafe.

 

2. I-RFID esebenzayo

I-RFID esebenzayo ingatsho ukuba i-rfid esebenzayo, engazange ithandwa ixesha elide xa ithelekiswa ne-rfid ye-RFI. Nangona kunjalo, inyani ikwimeko yethu yobomi bemihla ngemihla, njengenkqubo yokuqokelelwa kwe-elektroniki (njl) kwiindlela eziphezulu. Njengoko igama licebisa, i-RFID esebenzayo ifuna ukuhanjiswa kwamandla ngaphandle kunye nokuthumela ngenyameko imiqondiso yabafundi abayi-RFID. Ubungakanani bayo bukhulu, kodwa ikwanomgama omde kunye nesantya esiphezulu sokuhambisa, ezinye zinokufikelela kwiimitha ezili-100. I-RFID ye-RFID esebenzayo ikakhulu ikwinqanaba eliphezulu le-900mhz, 2.45ghz, i-5.8gz, njlz, njl

 

I-3. Semi esebenzayo rfid

Ngenxa yezibonelelo kunye nokungalunganga kokubini kwe-RFID kunye ne-RFID esebenzayo, i-RFID esebenzayo inomgama omfutshane. Nangona i-RFID esebenzayo inomgama omde, ifuna ukuhambisa amandla angaphandle kwaye inomthamo omkhulu. Ngenxa yemfuno yentengiso, le-} Inkqubo ye-RFID esebenzayo ivele, eza kunikezelwa ngamandla amandla kwaye ihlala ikwimeko yokulala. Ayisebenzi kwaye ayithumeli imiqondiso. Isebenza kuphela xa i-tag ingena phantsi -} i-frequency arhente yoluhlu, ukuze igcinwe igcinwe ixesha elide.
