Amavu n'amavuko
Ikoranabuhanga rya RFID ni tekinoroji yo kumenyekanisha mu buryo bwikora ishingiye ku bimenyetso bidafite umugozi kandi birakwiriye mu buryo butandukanye bwo gukoresha. Irimo kwitabwaho cyane mumasomero, inyandiko nubuyobozi bwububiko. Wongeyeho Ibirango by'isomero rya RFID kubitabo, inyandiko nububiko, imikorere nko gusoma byikora, kubaza, kugarura no kugaruka birashobora kugerwaho, kuzamura imikorere yubuyobozi hamwe nurwego rwa serivise y'ibitabo.
Hariho ubwoko bubiri bwingenzi bwaIbiranga RFID kubitabo ikoreshwa mu masomero no kubika inyandiko zicunga, ibirango bya RFID HF na Ibirango bya RFID UHF. Ibirango byombi bifite imiterere itandukanye. Reka nsesengure itandukaniro ryabo hepfo:
Ikoranabuhanga rya RFID rishobora kugabanwa muburyo butandukanye ukurikije imirongo itandukanye ikora: inshuro nke (LF), inshuro nyinshi (HF), ultra high frequency (UHF) na microwave (MW). Muri byo, inshuro nyinshi na ultra-high frequency ni ibitabo bibiri bikoreshwa cyane kuri tekinoroji ya RFID kuri ubu. Buriwese afite ibyiza bye nimbibi, kandi afite uburyo butandukanye muburyo butandukanye.
Ihame ryakazi: Ikorana buhanga rya RFID ikoresha ihame ryo guhuza umurima-inductive guhuza, ni ukuvuga, umusomyi yohereza ingufu kandi agahana amakuru hamwe na tagi binyuze mumashanyarazi. Ikoranabuhanga rya UHF RFID rikoresha ihame ryimirasire ya elegitoroniki ya elegitoroniki, ni ukuvuga, umusomyi yohereza ingufu kandi agahana amakuru hamwe na tagi binyuze mumashanyarazi.
Isesengura ryo guhitamo ibicuruzwa
1. Chips:HF irasaba gukoresha chip ya NXP ICODE SLIX, ikurikiza protocole ISO15693 na ISO / IEC 18000-3 Mode 1. Ifite ububiko bunini bwa EPC bwibice 1024, amakuru yayo ashobora kwandikwa inshuro 100.000 kandi akazigama imyaka irenga 10.
UHF irasaba gukoresha NXP UCODE 8, Alien Higgs 4, yubahiriza protocole ISO 18000-6C na EPC C1 Gen2, EPC. Ifite 128 yibikoresho byabakoresha, 32.amakuru yabo ashobora kwandikwa inshuro 100.000 kandi akazigama imyaka irenga 10.
2. Antenna: Antenna ya HF iroroshye cyane, igabanya ingaruka zo guhuza ibikorwa byinshi. Imirasire ya electromagnetic irashobora kwimura ingufu kuri tagi inyuma yabo binyuze muri antene. Nibisanzwe cyane muburyo bugaragara, buke mubiciro, byiza mubikorwa, kandi birahishwa cyane. Kubwibyo, 13.56mhz yubwenge nfc Ibitabo byibitabo bya RFID birakwiriye gucunga ibitabo nagasanduku k'ububiko. Nyamara, mugucunga dosiye imwe, ikoreshwa cyane cyane kumadosiye y'ibanga cyane, nk'inyandiko y'ibanga ryo hejuru, amadosiye y'ingenzi y'abakozi, ibishushanyo mbonera, n'inyandiko y'ibanga. Hano hari page imwe cyangwa nkeya muriyi nshingano. Gukoresha 13.56mhz HF rfid ibirango byibitabo bizuzuzanya cyane, bitera kwivanga, bigira ingaruka kumyizerere, no kutuzuza ibisabwa mubuyobozi. Muri iki kibazo, birasabwa gukoresha igisubizo cya UHF.
3. Ibikoresho byo hejuru: HF na UHF byombi birashobora gukoresha impapuro zubuhanzi nkibikoresho byo hejuru, kandi birashobora gucapa inyandiko yihariye, imiterere cyangwa barcode. Niba udakeneye gucapa, urashobora gukoresha inlay itaziguye.
4. Glue: Porogaramu ya tagi isanzwe ishyirwa kumpapuro. Biroroshye gukomera kandi imikoreshereze yimikoreshereze ntabwo ikaze. Ubushuhe buke buhendutse bushonga cyangwa kole y'amazi birashobora gukoreshwa.
5. Kurekura impapuro: Mubisanzwe, impapuro zishyigikiwe nikirahure hamwe na peteroli ya silicone ikoreshwa, idafatanye kandi byoroshye gusenya ikirango.
6. Urutonde rwo gusoma: Tekinoroji ya HF RFID ni tekinoroji yo guhuza ibikorwa, kandi ibikorwa byayo ni bito, muri santimetero 10. Ikoranabuhanga rya UHF RFID ni tekinoroji ya elegitoroniki ya electronique. Umuyoboro wa electromagnetic ufite urwego runaka rwo kwinjira kandi urwego rwakazi ni runini, muri rusange zirenga metero 1. Intera yo gusoma ya HF ni nto, irashobora rero kubona neza ibitabo cyangwa ububiko bwa dosiye.
7. Umuvuduko wo gusoma: Bitewe no kugarukira hafi yumurima wo guhuza inductive, tekinoroji ya HF RFID ifite umuvuduko wo gusoma buhoro kandi biragoye gusoma tagi nyinshi icyarimwe. Bitewe nibyiza byamahame ya radiyo yumuriro wa elegitoroniki, tekinoroji ya UHF RFID ifite umuvuduko wo gusoma byihuse hamwe numurimo wo gusoma mumatsinda. Tekinoroji ya UHF ifite intera ndende yo gusoma kandi yihuta yo gusoma, bityo bizarushaho gukora neza mugihe cyo kubara ibitabo cyangwa dosiye.
8. Ubushobozi bwo kurwanya kwivanga: Ihuriro ryegereye-inductive ya tekinoroji ya RFID igabanya umuvuduko mwinshi wa interineti, bigatuma ikoranabuhanga ryihuta cyane "ririnda" urusaku rwibidukikije no kwivanga kwa electronique (EMI), bityo rikaba rifite ubushobozi bukomeye bwo kurwanya kwivanga. UHF ikoresha ihame ryo gusohora amashanyarazi, bityo rero birashoboka cyane kwivanga kwa electronique. Muri icyo gihe, icyuma kizerekana ibimenyetso kandi amazi ashobora gukuramo ibimenyetso. Izi ngingo zizabangamira imikorere isanzwe ya Ikirango cya UHF RFID. Nubwo bamweUHF passiyo ya RFID nyuma yiterambere ryikoranabuhanga rifite imikorere myiza mukurinda kwivanga kwibyuma namazi, ugereranije nibirango byihuta cyane, UHF iracyari hasi gato, kandi nubundi buryo bugomba gukoreshwa kugirango bivemo.
9. Ubushobozi bwo kurwanya ubujura: Ikoreshwa ryaisomero RFID umutekano irwanya ubujuraifatanije numuyoboro umeze nkumuryango hamwe na sisitemu birashobora gukumira neza ibitabo na dosiye kubura no gushyira mubikorwa ibikorwa byo gutabaza bitemewe.HF na UHF RFID ibisubizo buriwese afite ibyiza bye nibibi, kandi guhitamo bigomba gupimwa no kugereranwa ukurikije ibikenewe nibisabwa.
