Ikhadi lethegi le RFID (I-Radio Frequency Identification) inlay emanzi iwuphawu oluncane oluncane, oluguquguqukayo olunomjikelezo oshumekiwe we RFID , ohlanganisa uthi ne-microchip. Lawa ma-inlay asetshenziselwa ukwenza amakhadi e RFID , akwazi ukugcina futhi adlulisele idatha ngokungenantambo uma askeniwe ngumfundi we RFID . Avame ukutholakala emakhadini okulawula ukufinyelela, amakhadi okukhokha ngaphandle kokuthinta, nakumakhadi ahlakaniphile ahlukahlukene.
Ibanga lokufunda, elibizwa nangokuthi ibanga lokufunda, liyipharamitha ebalulekile kubuchwepheshe be RFID . Isho ibanga eliphakeme lapho umfundi we RFID angakwazi ukuxhumana ngempumelelo nomaka we RFID . Ibanga elifundwayo linquma ukuthi ikhadi RFID lingaba kude kangakanani nomfundi ngenkathi lisatholwa futhi lifundwa ngokunembile. Lokhu kubalulekile ukuze kuqinisekiswe ukusebenza kahle nokusebenza kahle kwezinhlelo ze RFID ezinhlelweni ezihlukene.
Amathegi e RFID asebenza kumabanga ahlukene wokuvama: imvamisa ephansi ( LF ), imvamisa ephezulu ( HF ), kanye ne-ultra-high frequency ( UHF ). Ukuvama kuthinta kakhulu ibanga lokufunda. Omaka be- LF ngokuvamile banobubanzi obufushane bokufunda kodwa abasengozini yokuphazamiseka okuvela ezinsimbi noketshezi. Omaka be- HF banikeza amabanga okufunda amaphakathi futhi avame ukusetshenziswa emakhadini okukhokha ngaphandle kokuthinta. Omaka be- UHF bahlinzeka ngamabanga amade kakhulu okufundwayo kodwa bangase bathintwe kakhulu izici zemvelo.
Usayizi nomklamo we-antenna ngaphakathi kwekhadi lethegi le RFID elimanzi lidlala indima ebalulekile ekunqumeni ibanga elifundwayo. Ama-antenna amakhulu ngokuvamile ahlinzeka ngobubanzi obukhulu bokufunda ngenxa yokwamukela isignali okuthuthukisiwe. Ukwengeza, ukwakheka nokuma kwe-antenna kungaba nomthelela ekusebenzeni kahle kwendawo kazibuthe kagesi, ngaleyo ndlela kuthinte ibanga elifundwayo.
Izici zemvelo ezifana nokuba khona kwezinsimbi, uketshezi, nokuphazamiseka kazibuthe kagesi kungaba nomthelela ebangeni elifundwayo lamathegi e RFID . Izingxenye zensimbi zingabonisa futhi zimunce amasiginali e-RF, zehlise ububanzi bokufunda obusebenzayo. Ngokufanayo, uketshezi lungakhipha i-antenna, kubangele ukwehla kokusebenza. Izimo zemvelo kufanele zicatshangelwe lapho kwakhiwa futhi kuthunyelwa amasistimu e RFID ukuze kuqinisekiswe amabanga afanele okufunda.
Omaka be-Passive RFID abanawo umthombo wamandla wangaphakathi. Bathembele emandleni akhishwa ngumfundi we RFID ukuze anike amandla i-microchip futhi adlulisele idatha. Omaka abangenzi lutho babiza kakhulu futhi bafanele izinhlelo zokusebenza eziningi, kodwa ibanga labo lokufunda lifushane uma liqhathaniswa nomaka abasebenzayo.
Omaka abasebenzayo be RFID banomthombo wabo wamandla, ngokuvamile ibhethri, okubavumela ukuthi bathumele amasignali ebangeni elikhulu. Laba bomaki balungele izinhlelo zokusebenza ezidinga ububanzi bokufunda obude namazinga aphezulu okudlulisela idatha. Nokho, abiza kakhulu futhi anesikhathi esilinganiselwe sokusebenza ngenxa yezinkinga zebhethri.
Omaka be-Semi-passive RFID , abaziwa nangokuthi omaka abasizwa ibhethri (BAP), bahlanganisa izici zabo bobabili omaka abazenzayo nabasebenzayo. Anebhethri elincane ukunika amandla i-microchip, ethuthukisa ibanga lokufunda nokuthembeka kuyilapho zisathembele kusignali yomfundi ukuze kusebenze ukudluliswa kwedatha. Laba bomaka banikeza ibhalansi phakathi kokusebenza nezindleko.
Ibanga lokufunda lichazwa njengobubanzi obukhulu lapho umfundi we RFID angathola futhi axhumane nomaka we RFID . Leli banga likalwa ngaphansi kwezimo ezithile, ngokuvamile endaweni elawulwayo, ukuze kunqunywe ukusebenza okuphelele kohlelo lwe RFID . Isilinganiso sicabangela izici ezifana nokuma kwethegi, ukuphuma kwamandla omfundi, nezimo zemvelo.
Izinto ezimbalwa zingathuthukisa ibanga lokufunda lamathegi e RFID , okuhlanganisa:
Ukwandisa amandla okukhiphayo komfundi we RFID .
Ukuthuthukisa idizayini ye-antenna nokuma kwayo.
Ukusebenzisa amathegi efrikhwensi aphezulu (isb, UHF ) kumabanga amade okufunda.
Ukunciphisa ukuphazamiseka kwemvelo ngokukhetha izinto ezifanele kanye nezindawo zokuthunyelwa.
RFID izilayishi ezimanzi zekhadi lethegi zisetshenziswa kakhulu kumasistimu okulawula ukufinyelela ukuze kungene ngokuvikelekile ezakhiweni, emagumbini nasezindaweni ezikhawulelwe. Ibanga elifundwayo lawa makhadi livumela abasebenzisi ukuthi bathole ukungena ngaphandle kokuxhumana okuqondile nomfundi, okwenza kube lula nokuvikeleka.
Ekulawulweni kwe-inventory, RFID ama-tag card inlays afakwe emanzini asiza ukulandelela nokuphathwa kwezimpahla ezindaweni zokugcina izimpahla nasezindaweni zokudayisa. Ibanga elinwetshiwe lokufunda lamathegi e RFID livumela ukuskena okuphumelelayo kwezinto kusukela kude, ukuthuthukisa ukunemba kwe-inventory kanye nokunciphisa umsebenzi wezandla.
Amakhadi e-Smart card anokufakwa okumanzi kwekhadi lethegi le- RFID asetshenziswa ezinhlelweni zokusebenza ezihlukahlukene, okuhlanganisa amasistimu okukhokha ngaphandle kokuthinta, ezokuthutha zomphakathi, namakhadi okuhlonza. Ibanga elifundwayo lawa makhadi liqinisekisa ukuthengiselana okusheshayo nokungenazihibe kanye nezinqubo zokuhlonza.
Ibanga lokufunda lithinta ngokuqondile ukusebenza nokuthembeka kwamakhadi e RFID . Amakhadi anobubanzi obunganele bokufunda angase adinge abasebenzisi ukuthi basondele kakhulu kumfundi, abangele ukuphazamiseka kanye nokubambezeleka okungaba khona kokusebenza. Ukuqinisekisa ibanga elanele lokufunda kuthuthukisa ulwazi lomsebenzisi nokusebenza kahle kwesistimu.
Lapho uklama amakhadi e RFID , izici ezimbalwa kufanele zicatshangelwe ukuze kuzuzwe ukusebenza okuhle kokufunda. Lokhu kufaka phakathi ukukhetha uhlobo lwethegi ye- RFID efanele, ukuthuthukisa idizayini ye-antenna, nokucabangela indawo yohlelo lokusebenza oluhlosiwe. Idizayini efanele iqinisekisa ukuthi amakhadi asebenza ngendlela enokwethenjelwa nangempumelelo ezimweni zawo zokusebenzisa ezimisiwe.
Ukuthuthuka kwesikhathi esizayo kubuchwepheshe be RFID kulindeleke ukuthi kuthuthukise amakhono okufunda ibanga ngokuqhubekayo. Ukuthuthuka ekwakhiweni kwe-antenna, ukucutshungulwa kwesignali, nokuphathwa kwamandla kuzonikela kumabanga okufunda amade namasistimu RFID athembeke kakhulu.
Ukuhlanganiswa kobuchwepheshe be RFID ne-inthanethi Yezinto (IoT) namadivayisi ahlakaniphile kuyithrendi ekhulayo. Lokhu kuhlangana kuvumela ukuqoqwa kwedatha okuyinkimbinkimbi kakhulu, ukulandelela ngesikhathi sangempela, nokuzenzakalela okuthuthukisiwe, okusebenzisa amandla ebanga lokufunda RFID 's ukuze uthole amasistimu asebenza kahle kakhulu naxhumene.
RFID ama-inlay amanzi ekhadi lethegi ayingxenye ebalulekile ezinqubweni zesimanje zokwenza amakhadi, ahlinzeka ngemisebenzi ehlukahlukene ngokudluliswa kwedatha okungenantambo. Ukuqonda nokuthuthukisa ibanga lokufunda kubalulekile ukuze kuqinisekiswe ukusebenza kahle nokuthembeka kwezinhlelo ze RFID . Ngokucabangela izici ezifana nemvamisa, idizayini ye-antenna, nezimo zemvelo, abakhiqizi bangathuthukisa amabanga okufunda futhi bathole ukusebenza okungaguquki ezinhlelweni ezihlukene. Njengoba ubuchwepheshe be RFID buqhubeka nokuvela, ukuthuthuka ekwakhiweni kwe-antenna nokuhlanganiswa ne-IoT kuthembisa amandla amakhulu nokusebenza kahle.
