Ingemuva nohlelo lokusebenza
Ubuchwepheshe be-RFID ubuchwepheshe bokuhlonza obuzenzakalelayo obusekelwe kumasignali angenantambo futhi bufanele izimo ezihlukahlukene zohlelo. Ithola ukunakwa okwengeziwe emitatsheni yolwazi, imibhalo kanye nokuphathwa kwengobo yomlando. Ngokungeza amalebula e-RFID ezincwadini, kumadokhumenti nasezinqolobaneni, imisebenzi efana nokufunda okuzenzakalelayo, umbuzo, ukubuyisa nokubuyisela ingafezeka, ukuthuthukisa ukusebenza kahle kokuphatha kanye nezinga lensizakalo yezinto zezincwadi.
Kunezinhlobo ezimbili eziyinhloko zamalebula e-RFID asetshenziswa emitatsheni yolwazi nokuphathwa kwemibhalo egciniwe, amalebula e-RFID HF kanye namalebula e-RFID UHF. Lawa malebula amabili anezici ezihlukile. Ake ngihlaziye umehluko wabo ngezansi:
Ubuchwepheshe be-RFID bungahlukaniswa ngezinhlobo eziningana ngokuya ngamaza okusebenza ahlukene: imvamisa ephansi (LF), i-high frequency (HF), i-ultra high frequency (UHF) ne-microwave (MW). Phakathi kwazo, imvamisa ephezulu kanye ne-ultra-high iwubuchwepheshe obubili obusetshenziswa kakhulu be-RFID njengamanje. Ngayinye inezinzuzo zayo kanye nemikhawulo yayo, futhi inokusebenza okuhlukile ezimeni ezahlukene.
Umgomo wokusebenza: Ubuchwepheshe be-RFID be-high-frequency isebenzisa umgomo wokuhlanganisa inductive eduze nendawo, okungukuthi, umfundi udlulisa amandla futhi ashintshisane ngedatha nomaka ngokusebenzisa inkambu kazibuthe. Ubuchwepheshe be-UHF RFID busebenzisa isimiso semisebe ye-electromagnetic ekude, okungukuthi, umfundi udlulisa amandla futhi ashintshisane ngedatha nomaka ngokusebenzisa amaza kagesi.
Ukuhlaziywa kokukhethwa komkhiqizo
1. Ama-chips:I-HF incoma ukusebenzisa i-NXP ICODE SLIX chip, ethobela izimiso ISO15693 kanye ne-ISO/IEC 18000-3 Mode 1. Inenkumbulo enkulu ye-EPC yamabhithi angu-1024, ingabhala kabusha idatha izikhathi ezingu-100,000, futhi ingalondoloza idatha iminyaka engaphezu kwengu-10.
I-UHF incoma ukusebenzisa i-NXP UCODE 8, i-Alien Higgs 4, ethobela izivumelwano ISO 18000-6C kanye ne-EPC C1 Gen2, EPC, inkumbulo yomsebenzisi engu-128 bit, engaphinda ibhale idatha izikhathi ezingu-100,000, futhi idatha ingalondolozwa ngaphezu kuka-10 iminyaka.
2. Izimpondo: Ama-antenna e-HF azacile uma kuqhathaniswa, okunciphisa umthelela wokuphazamiseka wokupakishwa kwamathegi amaningi. Amagagasi kagesi angadlulisela amandla athile kumathegi angemuva kwawo ngothi. Zizacile kakhulu ngokubukeka, izindleko eziphansi, ukusebenza kahle kakhulu, futhi zifihleka kakhulu. Ngakho-ke, amalebula e-HF afanele ukuphathwa kwezincwadi namabhokisi engobo yomlando. Kodwa-ke, ekuphathweni kwefayela lekhasi elilodwa, lisetshenziselwa ikakhulukazi amafayela ayimfihlo kakhulu, njengamadokhumenti ayimfihlo, amafayela abalulekile ezisebenzi, imidwebo yokuklama, kanye nemibhalo eyimfihlo. Kunekhasi elilodwa kuphela noma ambalwa kulawa maphothifoliyo. Ukusebenzisa omaka be-HF kuzogqagqana eduze, kubangele ukuphazamiseka okufanayo, kuthinte ukunemba kokubonwa, nokwehluleka ukuhlangabezana nezidingo zokuphatha. Kulokhu, kunconywa ukusebenzisa isisombululo sokulebula se-UHF.
3. Izinto ezingaphezulu: Kokubili i-HF ne-UHF ingasebenzisa iphepha lobuciko njengento engaphezulu, futhi ingaphrinta umbhalo owenziwe ngokwezifiso, amaphethini noma amabhakhodi. Uma ungadingi ukuphrinta, ungasebenzisa inlay emanzi ngokuqondile.
4. Ingcina: Isimo sokusetshenziswa kwamathegi sivamise ukunamathiselwa ephepheni. Kulula ukunamathela futhi imvelo yokusetshenziswa ayinalo ukhahlo. I-adhesive encibilikayo eshibhile eshibhile eshibhile eshibhile ngokuvamile ingasetshenziswa.
5. Iphepha lokukhishwa:Ngokuvamile, kusetshenziswa iphepha eline-glassine-backed oil layer ye-silicone, elinganamatheli futhi lenza kube lula ukudabula ithegi.
6. Ibanga lokufunda: Ubuchwepheshe be-HF RFID ubuchwepheshe bokuhlanganisa obuseduze kwenkundla, futhi uhla lwabo lokusebenza luncane, ngokuvamile phakathi kwamasentimitha ayi-10. Ubuchwepheshe be-UHF RFID ubuchwepheshe bemisebe ye-electromagnetic ekude. Igagasi logesi linezinga elithile lokungena futhi ububanzi balo bokusebenza likhulu, ngokuvamile lingaphezu kwemitha elingu-1. Ibanga lokufunda le-HF lincane, ngakho lingakwazi ukuthola izincwadi ngokunembile noma amafayela agcine kungobo yomlando.
7. Isivinini sokufunda: Ngenxa yomkhawulo wesimiso sokuhlanganisa esiseduze nenkundla, ubuchwepheshe be-HF RFID bunesivinini sokufunda esinensayo futhi kunzima ukufunda omaka abaningi ngesikhathi esisodwa. Ngenxa yezinzuzo zesimiso semisebe ye-electromagnetic ekude, ubuchwepheshe be-UHF RFID bunesivinini sokufunda esisheshayo nomsebenzi wokufunda weqembu. Ubuchwepheshe be-UHF bunebanga lokufunda elide kanye nesivinini sokufunda esisheshayo, ngakho buzosebenza kahle kakhulu lapho kufakwa uhlu lwezincwadi noma amafayela.
8. Amandla okumelana nokugxambukela: I-Near-field inductive coupling yobuchwepheshe be-RFID be-high-frequency kunciphisa ukuphazamiseka okungaba khona okungenantambo, okwenza ubuchwepheshe be-high-frequency "buvikeleke" ngokwedlulele emsindweni wemvelo kanye nokuphazanyiswa kwe-electromagnetic interference (EMI), ngakho-ke inekhono eliqinile lokulwa nokuphazamiseka. . I-UHF isebenzisa umgomo wokuphuma kuka-electromagnetic, ngakho-ke isengozini enkulu yokuphazamiseka kazibuthe kagesi. Ngesikhathi esifanayo, insimbi izobonisa amasignali futhi amanzi angakwazi ukudonsa amasignali. Lezi zici zizophazamisa ukusebenza okuvamile kwelebula Nakuba ezinye izitika ze-UHF ngemva kokuthuthukiswa kobuchwepheshe zisebenza kahle kakhulu ekuvimbeleni ukuphazamiseka kwezinsimbi noketshezi, uma kuqhathaniswa namalebula amaza aphezulu, i-UHF isengaphansi kancane, futhi ezinye izindlela zidinga ukusetshenziswa ukuze lungisa.
9. Ukusetshenziswa kwamalebula e-RFID ngokuhambisana namashaneli namasistimu amise okwesicabha kungavimbela ngokuphumelelayo amabhuku namafayela ekulahlekeni futhi kuqalise imisebenzi ye-alamu yokususa engekho emthethweni.
Izixazululo ze-HF ne-UHF RFID ngasinye sinezinzuzo nezinkinga zaso, futhi ukukhetha kufanele kukalwe kuqhathaniswe ngokusekelwe ezidingweni nezimo ezithile.
