Ingemuva kanye Nokusetshenziswa
Ubuchwepheshe be-RFID buwubuchwepheshe bokuhlonza okuzenzakalelayo obusekelwe kumasignali angenantambo futhi bufanelekela izimo ezahlukahlukene zohlelo lokusebenza. Buthola ukunakwa okwengeziwe emitatsheni yezincwadi, ekuphathweni kwemibhalo kanye nengobo yomlando. Ngokungeza Amalebula omtapo wezincwadi we-RFID ezincwadini, emadokhumendeni nasezingobo zomlando, imisebenzi efana nokufunda okuzenzakalelayo, ukubuza imibuzo, ukubuyisa kanye nokubuyisela kungafezwa, okuthuthukisa ukusebenza kahle kokuphatha kanye nezinga lenkonzo yezinto zezincwadi.
Kunezinhlobo ezimbili eziyinhloko ze-Amathegi e-RFID ezincwadi isetshenziswa emitatsheni yezincwadi kanye nasekuphathweni kwemibhalo egciniwe, amalebula e-RFID HF kanye Amalebula e-RFID UHFLawa malebula amabili anezici ezahlukene. Ake ngihlaziye umehluko wawo ngezansi:
Ubuchwepheshe be-RFID bungahlukaniswa ngezinhlobo eziningana ngokuya ngamaza okusebenza ahlukene: imvamisa ephansi (LF), imvamisa ephezulu (HF), imvamisa ephezulu kakhulu (UHF) kanye ne-microwave (MW). Phakathi kwazo, imvamisa ephezulu kanye nemvamisa ephezulu kakhulu yizincwadi ezimbili ezisetshenziswa kakhulu kubuchwepheshe be-RFID okwamanje. Ngayinye inezinzuzo zayo kanye nemikhawulo yayo, futhi inokusebenza okuhlukile ezimweni ezahlukene.
Umgomo Wokusebenza: Ubuchwepheshe be-RFID obusebenzisa imvamisa ephezulu busebenzisa umgomo wokuxhumanisa okubangela umthelela eduze kwensimu, okungukuthi, umfundi udlulisela amandla futhi ashintshane ngedatha nethegi ngensimu yamagnetic. Ubuchwepheshe be-UHF RFID busebenzisa umgomo wokukhanya kwe-electromagnetic okude, okungukuthi, umfundi udlulisela amandla futhi ashintshane ngedatha nethegi ngamagagasi kagesi.
Ukuhlaziywa kokukhethwa komkhiqizo
1. Ama-chips:I-HF incoma ukusebenzisa i-chip ye-NXP ICODE SLIX, ehambisana nezinqubo ze-ISO15693 kanye ne-ISO/IEC 18000-3 Mode 1. Inememori enkulu ye-EPC yama-bits angu-1024, idatha yayo ingabhalwa kabusha izikhathi ezingu-100,000 futhi ilondolozwe iminyaka engaphezu kwengu-10.
I-UHF incoma ukusebenzisa i-NXP UCODE 8, i-Alien Higgs 4, ehambisana nemigomo ye-ISO 18000-6C kanye ne-EPC C1 Gen2, i-EPC. Inememori yomsebenzisi engu-128 bit, engu-32. idatha yayo ingabhalwa kabusha izikhathi ezingu-100,000 futhi ilondolozwe iminyaka engaphezu kwengu-10.
2. Ama-antenna: Ama-antenna e-HF mancane kakhulu, okunciphisa umphumela wokuphazamiseka kokufakwa kwamathegi amaningi. Amagagasi e-electromagnetic angadlulisela amandla athile kumathegi angemuva kwawo nge-antenna. Abukeka emancane kakhulu, aphansi ngezindleko, asebenza kahle kakhulu, futhi afihleka kakhulu. Ngakho-ke, amathegi omtapo wolwazi we-13.56mhz smart nfc RFID afanele ukuphathwa kwezincwadi namabhokisi okugcina umlando. Kodwa-ke, ekuphathweni kwamafayela ekhasi elilodwa, asetshenziswa kakhulu kumafayela ayimfihlo kakhulu, njengemibhalo eyimfihlo ephezulu, amafayela abasebenzi abalulekile, imidwebo yokuklama, kanye nemibhalo eyimfihlo. Kunekhasi elilodwa noma ambalwa kuphela kula maphothifoliyo. Ukusebenzisa amalebula omtapo wolwazi we-HF rfid we-13.56mhz kuzohlangana eduze, kubangele ukuphazamiseka okufanayo, kuthinte ukunemba kokuqashelwa, futhi kwehluleke ukuhlangabezana nezidingo zokuphatha. Kulokhu, kunconywa ukusebenzisa isisombululo sokumaka se-UHF.
3. Izinto ezisetshenziswayo: Kokubili i-HF ne-UHF zingasebenzisa iphepha lobuciko njengezinto zokwakha, futhi zingaphrinta umbhalo, amaphethini noma amabhakhodi enziwe ngokwezifiso. Uma ungadingi ukuphrinta, ungasebenzisa i-wet inlay ngqo.
4. Iglu: Isimo sokusetshenziswa kwamathegi sivame ukunamatheliswa ephepheni. Kulula ukunamathelisa futhi indawo yokusetshenziswa ayinzima. I-glue encibilikayo eshisayo noma amanzi ingasetshenziswa.
5. Iphepha lokukhululwa: Ngokuvamile, kusetshenziswa iphepha elingemuva lengilazi elinesendlalelo samafutha e-silicone, elinganamatheli futhi elenza kube lula ukulidabula.
6. Uhla lokufunda: Ubuchwepheshe be-HF RFID buwubuchwepheshe bokuxhumanisa obuseduze nensimu, futhi ububanzi bawo bokusebenza buncane, ngokuvamile bungaphakathi kwamasentimitha ayi-10. Ubuchwepheshe be-UHF RFID buwubuchwepheshe bokukhanya kwe-electromagnetic obukude nensimu. Igagasi le-electromagnetic linezinga elithile lokungena futhi ububanzi balo bokusebenza bukhulu, ngokuvamile bungaphezu kwemitha eli-1. Ibanga lokufunda le-HF lincane, ngakho-ke lingathola ngokunembile izincwadi noma amafayela okugcina umlando.
7. Isivinini sokufunda: Ngenxa yokulinganiselwa kwesimiso sokuxhumanisa esiseduze nensimu, ubuchwepheshe be-HF RFID bunesivinini sokufunda esihamba kancane futhi kunzima ukufunda amathegi amaningi ngesikhathi esisodwa. Ngenxa yezinzuzo zesimiso sokukhanya kwe-electromagnetic esikude, ubuchwepheshe be-UHF RFID bunesivinini sokufunda esisheshayo kanye nomsebenzi wokufunda weqembu. Ubuchwepheshe be-UHF bunebanga elide lokufunda kanye nesivinini sokufunda esisheshayo, ngakho-ke buzosebenza kahle kakhulu lapho kufakwa ohlwini lwezincwadi noma amafayela.
8. Ikhono lokulwa nokuphazamiseka: Ukuhlanganiswa kwe-RFID ehambisana nensimu kunciphisa ukuphazamiseka okungaba khona okungenantambo, okwenza ubuchwepheshe be-RFID ehambisana nesivinini esikhulu "buvikeleke" kakhulu emsindweni wemvelo kanye nokuphazamiseka kwe-electromagnetic (EMI), ngakho-ke bunamandla amakhulu okulwa nokuphazamiseka. I-UHF isebenzisa isimiso sokukhishwa kwe-electromagnetic, ngakho-ke isengozini enkulu yokuphazamiseka kwe-electromagnetic. Ngesikhathi esifanayo, insimbi izobonakalisa izimpawu futhi amanzi angamunca izimpawu. Lezi zici zizophazamisa umsebenzi ojwayelekile we Ilebula le-UHF RFIDNakuba abanyeAmathegi e-UHF angasebenzi e-RFID Ngemva kokuba ukuthuthukiswa kobuchwepheshe kube nokusebenza okuhle kakhulu ekuvimbeleni ukuphazamiseka okuvela ezinsimbini nasezintweni eziwuketshezi, uma kuqhathaniswa namalebula avame kakhulu, i-UHF isesephansi kancane, futhi ezinye izindlela zidinga ukusetshenziswa ukuze kulungiswe lokho.
9. Amandla okulwa nokweba: Ukusetshenziswa kweamalebula okuphepha e-RFID yomtapo wolwaziNgokuhambisana neziteshi nezinhlelo ezimise okwesicabha kungavimbela ngempumelelo izincwadi namafayela ukuthi angalahleki futhi kuqalise imisebenzi ye-alamu yokususa engekho emthethweni.Izixazululo ze-HF kanye ne-UHF RFID ngayinye inezinzuzo nezinkinga zayo, futhi ukukhetha kufanele kulinganiswe futhi kuqhathaniswe ngokusekelwe ezidingweni nasezimweni ezithile.
