Mbiri ndi Kugwiritsa Ntchito
Ukadaulo wa RFID ndi ukadaulo wodzizindikiritsa wokha wozikidwa pa ma signali opanda zingwe ndipo ndi woyenera kugwiritsa ntchito pazochitika zosiyanasiyana. Ukulandira chidwi chochulukirapo mu malaibulale, kasamalidwe ka zikalata ndi zosungira zakale. Powonjezera Zolemba za laibulale ya RFID Kupereka mabuku, zikalata ndi zosungira zakale, ntchito monga kuwerenga zokha, kufunsa mafunso, kupeza ndi kubweza mabuku zitha kuchitika, zomwe zimapangitsa kuti ntchito yoyang'anira mabuku ikhale yogwira mtima komanso kuti mabuku azigwiritsidwa ntchito bwino.
Pali mitundu iwiri ikuluikulu yaMa RFID tag a mabuku amagwiritsidwa ntchito m'malaibulale ndi kasamalidwe ka zikalata zakale, zilembo za RFID HF ndi Zolemba za RFID UHFZolemba ziwirizi zili ndi makhalidwe osiyana. Ndiloleni ndiwunike kusiyana kwawo pansipa:
Ukadaulo wa RFID ukhoza kugawidwa m'mitundu ingapo malinga ndi ma frequency osiyanasiyana ogwirira ntchito: ma frequency otsika (LF), ma frequency apamwamba (HF), ma frequency apamwamba kwambiri (UHF) ndi microwave (MW). Pakati pawo, ma frequency apamwamba kwambiri ndi ma frequency apamwamba kwambiri ndi mabuku awiri omwe amagwiritsidwa ntchito kwambiri paukadaulo wa RFID pakadali pano. Buku lililonse lili ndi zabwino zake komanso zofooka zake, ndipo limagwiritsidwa ntchito mosiyana pazochitika zosiyanasiyana.
Mfundo yogwirira ntchito: Ukadaulo wa RFID wothamanga kwambiri umagwiritsa ntchito mfundo yolumikizirana ndi inductive pafupi ndi field, kutanthauza kuti, wowerenga amatumiza mphamvu ndikusinthanitsa deta ndi chizindikiro kudzera mu magnetic field. Ukadaulo wa UHF RFID umagwiritsa ntchito mfundo ya radiation ya electromagnetic yakutali, kutanthauza kuti, wowerenga amatumiza mphamvu ndikusinthanitsa deta ndi chizindikiro kudzera mu mafunde a electromagnetic.
Kusanthula kusankha zinthu
1. Ma Chips:HF imalimbikitsa kugwiritsa ntchito chip ya NXP ICODE SLIX, yomwe imagwirizana ndi ma protocol a ISO15693 ndi ISO/IEC 18000-3 Mode 1. Ili ndi kukumbukira kwakukulu kwa EPC kwa ma bits 1024, komwe deta yake ingalembedwenso nthawi 100,000 ndikusungidwa kwa zaka zoposa 10.
UHF imalimbikitsa kugwiritsa ntchito NXP UCODE 8, Alien Higgs 4, mogwirizana ndi ma protocol a ISO 18000-6C ndi EPC C1 Gen2, EPC. Ili ndi memory ya ogwiritsa ntchito ya 128 bit, 32. deta yake ikhoza kulembedwanso nthawi 100,000 ndikusungidwa kwa zaka zoposa 10.
2. Ma antenna: Ma antenna a HF ndi ofooka pang'ono, zomwe zimachepetsa kusokoneza kwa ma multi-tag stacking. Mafunde amagetsi amatha kusamutsa mphamvu zina kupita ku ma tag omwe ali kumbuyo kwawo kudzera mu antenna. Ndi owoneka opyapyala kwambiri, otsika mtengo, ogwira ntchito bwino, komanso obisika kwambiri. Chifukwa chake, ma tag a laibulale a 13.56mhz anzeru a nfc RFID ndi oyenera kuyang'anira mabuku ndi mabokosi osungiramo zinthu zakale. Komabe, poyang'anira mafayilo a tsamba limodzi, amagwiritsidwa ntchito makamaka pamafayilo achinsinsi kwambiri, monga zikalata zachinsinsi kwambiri, mafayilo ofunikira a ogwira ntchito, zojambula za kapangidwe, ndi zikalata zachinsinsi. Pali tsamba limodzi kapena angapo m'ma portfolio awa. Kugwiritsa ntchito ma label a laibulale a 13.56mhz HF rfid kudzagwirizana kwambiri, zomwe zimayambitsa kusokonezana, kukhudza kulondola kwa kuzindikira, ndikulephera kukwaniritsa zofunikira za oyang'anira. Pankhaniyi, tikukulimbikitsani kugwiritsa ntchito njira yolembera ma UHF.
3. Zinthu zapamwamba: HF ndi UHF zonse zingagwiritse ntchito pepala la zaluso ngati zinthu zomangira pamwamba, ndipo zimatha kusindikiza zolemba, mapatani kapena ma barcode osinthidwa mwamakonda. Ngati simukufunika kusindikiza, mutha kugwiritsa ntchito wet inlay mwachindunji.
4. Guluu: Kagwiritsidwe ntchito ka ma tag nthawi zambiri kamamatiridwa papepala. N'kosavuta kumamatira ndipo malo ogwiritsira ntchito si ovuta. Guluu wotentha wosungunuka kapena guluu wamadzi wotsika mtengo nthawi zambiri ungagwiritsidwe ntchito.
5. Pepala lotulutsa: Kawirikawiri, pepala lokhala ndi galasi lokhala ndi silicone oil limagwiritsidwa ntchito, lomwe silimamatira ndipo limapangitsa kuti likhale losavuta kudula chizindikirocho.
6. Kuwerengera: Ukadaulo wa HF RFID ndi ukadaulo wolumikizirana womwe umagwiritsidwa ntchito pafupi ndi field inductive, ndipo malo ake ogwirira ntchito ndi ochepa, nthawi zambiri mkati mwa masentimita 10. Ukadaulo wa UHF RFID ndi ukadaulo wa radiation yamagetsi yakutali. Mafunde amagetsi ali ndi gawo linalake lolowera ndipo malo ake ogwirira ntchito ndi akulu, nthawi zambiri amakhala opitilira mita imodzi. Mtunda wowerengera wa HF ndi wochepa, kotero imatha kupeza mabuku kapena mafayilo osungidwa molondola.
7. Liwiro la kuwerenga: Chifukwa cha malire a mfundo yolumikizirana ya near-field inductive, ukadaulo wa HF RFID uli ndi liwiro lowerenga pang'onopang'ono ndipo n'zovuta kuwerenga ma tag angapo nthawi imodzi. Chifukwa cha ubwino wa mfundo ya radiation ya electromagnetic radiation, ukadaulo wa UHF RFID uli ndi liwiro lowerenga mwachangu komanso ntchito yowerengera gulu. Ukadaulo wa UHF uli ndi mtunda wautali wowerengera komanso liwiro lowerenga mwachangu, kotero udzakhala wogwira mtima kwambiri polemba mabuku kapena mafayilo.
8. Mphamvu yoletsa kusokoneza: Kulumikizana kwa ukadaulo wa RFID wapafupipafupi kumachepetsa kusokoneza kwa waya, zomwe zimapangitsa ukadaulo wa RFID wapafupipafupi kukhala "wotetezeka" kwambiri ku phokoso la chilengedwe ndi kusokoneza kwa electromagnetic (EMI), kotero uli ndi mphamvu yolimbana ndi kusokoneza. UHF imagwiritsa ntchito mfundo ya kutulutsa kwa electromagnetic, kotero imakhala yotetezeka kwambiri ku kusokoneza kwa electromagnetic. Nthawi yomweyo, chitsulo chidzawonetsa zizindikiro ndipo madzi amatha kuyamwa zizindikiro. Zinthu izi zidzasokoneza ntchito yachibadwa ya Chizindikiro cha UHF RFIDNgakhale enaMa tag a RFID osagwira ntchito a UHF Pambuyo poti kusintha kwa ukadaulo kwakhala ndi magwiridwe antchito abwino kwambiri popewa kusokonezedwa ndi zitsulo ndi zakumwa, poyerekeza ndi zilembo zama frequency apamwamba, UHF ikadali yotsika pang'ono, ndipo njira zina ziyenera kugwiritsidwa ntchito kuti zibwezeretsedwe.
9. Mphamvu yoletsa kuba: Kugwiritsa ntchitozilembo zoletsa kuba za laibulale ya RFIDMogwirizana ndi njira ndi machitidwe ooneka ngati chitseko, zimatha kuteteza mabuku ndi mafayilo kuti asatayike ndikuyambitsa ntchito zosaloledwa zochotsera zinthu.Mayankho a HF ndi UHF RFID aliwonse ali ndi zabwino ndi zovuta zake, ndipo kusankha kuyenera kuyezedwa ndikuyerekezeredwa kutengera zosowa ndi mikhalidwe inayake.
