Ma tag apakompyuta a RFID tsopano akugwiritsidwa ntchito kwambiri pakuwongolera malo osungiramo zinthu, kutsatira kasamalidwe kazinthu, kutsata chakudya, kasamalidwe kazinthu ndi magawo ena.
Pakadali pano, tchipisi tag tag za UHF RFID zomwe zimagwiritsidwa ntchito kwambiri pamsika zimagawidwa m'magulu awiri: zotumizidwa kunja ndi zapakhomo, kuphatikiza Makamaka IMPINJ, ALIEN, NXP, Kiloway, ndi zina.
1. Mlendo (USA)
M'mbuyomu, RFID tag H3 ya Alien (dzina lonse: Higgs 3) inalinso yotchuka kwambiri.Mpaka pano, chip ichi chakhala chikugwiritsidwa ntchito m'mapulojekiti ambiri am'mbuyomu.Malo akuluakulu osungirako ndi chimodzi mwa ubwino wake woonekeratu.
Komabe, ndi kutuluka kwa mapulogalamu atsopano osiyanasiyana ndi zofunikira zapamwamba komanso zapamwamba za mtunda wowerengera wa ma tag m'magawo atsopano, pang'onopang'ono zimakhala zovuta kuti kuwerenga kwa H3 kukwaniritse zofunikira.Alien adasinthanso ndikukweza tchipisi tawo, ndipo pambuyo pake panali H4 (Higgs 4), H5 (Higgs EC), ndi H9 (Higgs 9).
Tchipisi zotulutsidwa ndi Alien zidzakhala ndi mizere yamitundu yosiyanasiyana yamitundu yosiyanasiyana ndikugwiritsa ntchito.Izi zimawapatsa mwayi waukulu kukweza tchipisi tawo ndikukhala pamsika.Makasitomala ambiri ndi ogulitsa atha kupeza mwachindunji ma tag kuti agwiritse ntchito moyeserera, zomwe zimachepetsa nthawi ndi mtengo wopanga ma tinyanga.
Chifukwa chipwirikiti cha H9 ndi H3 tchipisi ndi chofanana, ndipo njira yolumikizira ma chip pin ndi yofanana, mlongoti wapagulu wa H3 wam'mbuyo ukhoza kulumikizidwa mwachindunji ku H9.Makasitomala ambiri omwe adagwiritsa ntchito chipangizo cha H3 m'mbuyomu amatha kugwiritsa ntchito chipangizochi mwachindunji popanda kusintha mlongoti, zomwe zimawasungira zinthu zambiri.Mitundu ya mizere yachilendo: ALN-9710, ALN-9728, ALN-9734, ALN-9740, ALN-9662, etc.
2. Impinj (USA)
Tchipisi za Impinj za UHF zimatchedwa mndandanda wa Monza.Kuchokera ku M3, M4, M5, M6, zasinthidwa kukhala M7 yaposachedwa.Palinso mndandanda wa MX, koma m'badwo uliwonse ukhoza kukhala ndi oposa mmodzi.
Mwachitsanzo, mndandanda wa M4 umaphatikizapo: M4D, M4E, M4i, M4U, M4QT.Mndandanda wonse wa M4 ndi chip-doko chapawiri, chomwe chitha kugwiritsidwa ntchito ngati chizindikiro chapawiri-polarization, kupeŵa mkhalidwe womwe chizindikiro cha polarization cha mzere ndi mtanda wa antenna polarization wowerengeka sungathe kuwerengedwa, kapena mtunda wowerengera wa polarization uli pafupi. .Ndikoyenera kunena kuti ntchito ya QT ya chipangizo cha M4QT ndi pafupifupi yapadera m'munda wonse, ndipo ili ndi njira ziwiri zosungiramo deta yapagulu ndi yachinsinsi, yomwe ili ndi chitetezo chapamwamba.
Ma tchipisi amtundu womwewo amakhala wosiyana kwambiri pakugawikana kwa malo osungirako ndi kukula kwake, ndipo kutsekereza kwawo, njira yomangirira, kukula kwa chip, ndi kukhudzika ndizofanana, koma zina zimakhala ndi ntchito zina zatsopano.Tchipisi za Impinj sizimasinthidwa kawirikawiri ndi zosintha, ndipo m'badwo uliwonse umakhala ndi malo ake owala komanso osasinthika.Kotero mpaka kutuluka kwa mndandanda wa M7, M4 ndi M6 akadali ndi msika waukulu.Zomwe zimapezeka kwambiri pamsika ndi M4QT ndi MR6-P, ndipo tsopano pali M730 ndi M750.
Pazonse, tchipisi ta Impinj zimasinthidwa pafupipafupi, kukhudzika kumakulirakulira, ndipo kukula kwa chip kukucheperachepera.Chip cha Impinj chikakhazikitsidwa, padzakhalanso mtundu wamtundu wamtundu wamtundu wa pulogalamu iliyonse.Mitundu ya mizere yapamwamba imaphatikizapo: H47, E61, AR61F, ndi zina.
3. NXP (Netherlands)
NXP's Ucode mndandanda wama tag a UHF amagwiritsidwa ntchito kwambiri pogulitsa zovala, kasamalidwe ka magalimoto, chitetezo chamtundu ndi zina.M'badwo uliwonse wa tchipisi tating'onoting'ono umatchulidwa molingana ndi momwe amagwiritsira ntchito, ena omwe ndi osowa pamsika chifukwa cha magawo awo ang'onoang'ono ogwiritsira ntchito.
Mibadwo ya U7, U8, ndi U9 pamndandanda wa Ucode ndiyo yomwe imagwiritsidwa ntchito kwambiri.Komanso monga Impinj, m'badwo uliwonse wa NXP uli ndi chip choposa chimodzi.Mwachitsanzo: U7 ikuphatikizapo Ucode7, Ucode7m, Ucode 7Xm-1k, Ucode 7xm-2K, Ucode 7xm+.Awiri oyambirira ndi okhudzidwa kwambiri, kukumbukira kochepa.Mitundu itatu yomalizayi imakhala ndi kukumbukira kwakukulu komanso kutsika pang'ono.
U8 yalowa m'malo mwa U7 pang'onopang'ono (kupatula ma memory chips atatu akulu a U7xm) chifukwa chakukhudzika kwake.Chip chaposachedwa cha U9 ndi chodziwikanso, ndipo chidwi chowerenga chimafika -24dBm, koma kusungirako kumakhala kochepa.
Tchipisi wamba za NXP zimakhazikika mu: U7 ndi U8.Mitundu yambiri ya ma label imapangidwa ndi opanga omwe ali ndi luso la R&D, ndipo mitundu yochepa yapagulu imawonedwa.
Izi zitha kukhala zomwe zimachitika pakukula kwa RFID tag padziko lonse lapansi:
1. Kukula kwa chip kumakhala kocheperako, kotero kuti zopyapyala zambiri zitha kupangidwa ndi kukula komweko, ndipo zotulutsa zimawonjezeka kwambiri;
2. Chidziwitso chikukwera kwambiri, ndipo tsopano chapamwamba kwambiri chafika -24dBm, chomwe chingakwaniritse zosowa za makasitomala kuti awerenge nthawi yayitali.Imagwiritsidwa ntchito m'magawo ambiri ndipo imathanso kuchepetsa kuchuluka kwa zida zowerengera zomwe zidayikidwa mu pulogalamu yomweyo.Kwa makasitomala otsiriza , kupulumutsa mtengo wa yankho lonse.
3. Kukumbukira kumakhala kocheperako, komwe kumawoneka ngati nsembe yomwe iyenera kupangidwa kuti ipititse patsogolo chidwi.Koma makasitomala ambiri safunikira kukumbukira zambiri, amangofunika kupanga ma code a zinthu zonse osabwerezedwa, ndi zina za chinthu chilichonse (monga: pamene chinapangidwa, kumene chakhala, chikachoka ku fakitale. , etc.) akhoza kufananizidwa kwathunthu mu dongosolo lomwe linalembedwa m'makhodi, ndipo sikoyenera kulemba zonse mu code.
Pakadali pano, IMPINJ, ALIEN, ndi NXP ndi omwe amakhala pamsika wambiri wa UHF wazinthu zonse.Opanga awa apanga zopindulitsa pazambiri za tchipisi tambiri.Chifukwa chake, osewera ena a UHF RFID tag chip ndiwowonjezera pakukula kwapadera kwa magawo ogwiritsira ntchito, Pakati pa opanga apakhomo, Sichuan Kailuwei apanga mwachangu pankhaniyi.
4. Sichuan Kailuway (China)
Pomwe msika wama tag a RFID watsala pang'ono kukhutitsidwa, Kailuwei adayatsa njira podalira ukadaulo wodzipangira yekha XLPM Ultra-low power permanent memory technology.Chilichonse cha tchipisi ta Kailuwei cha X-RFID chili ndi ntchito zake.Makamaka, mndandanda wapadera wa KX2005X uli ndi chidwi chachikulu komanso kukumbukira kwakukulu, zomwe sizipezeka pamsika, komanso zimakhala ndi ntchito za kuyatsa kwa LED, kuyang'ana pazidziwitso, ndi ma radiation odana ndi mankhwala.Ndi ma LED, ma tag akagwiritsidwa ntchito poyang'anira mafayilo kapena kasamalidwe ka laibulale, mutha kupeza mafayilo ndi mabuku omwe mukufuna mwachangu poyatsa ma LED, zomwe zimathandizira kwambiri kusaka.
Akuti adayambitsanso tchipisi tating'onoting'ono tating'ono: 1 NDI 2 YOKHA, zomwe zitha kuwonedwa ngati zatsopano mu tchipisi ta RFID.Imaphwanya stereotype ya magawo osungira chip cholembera, kusiya ntchito yolembanso zolemba, ndikukonza mwachindunji kachidindo ikachoka kufakitale.Ngati kasitomala safunikira kusintha kachidindo pambuyo pake, kugwiritsa ntchito njirayi kutha kuthetsa kutsanzira kwa zilembo zachinyengo, chifukwa chizindikiro chilichonse chimakhala chosiyana.Ngati akufuna kutsanzira, ayenera kuyamba ndi chophika chophika chokhazikika, ndipo mtengo wachinyengo ndi wokwera kwambiri.Mndandandawu, kuwonjezera pa zabwino zotsutsana ndi zachinyengo zomwe tazitchula pamwambapa, kukhudzidwa kwake kwakukulu ndi mtengo wotsika mtengo ukhoza kuonedwa ngati "okhawo" pamsika.
Kuphatikiza pa opanga ma tag a RFID UHF omwe adayambitsidwa pamwambapa, palinso em microelectronic (EM microelectronics ku Switzerland, chip yawo yapawiri-frequency ndi yoyamba padziko lapansi, ndipo ndi mtsogoleri wa tchipisi tapawiri-frequency), Fujitsu (Japan). Fujitsu), Fudan (Shanghai Fudan Microelectronics Group), CLP Huada, National Technology ndi zina zotero.
Shenzhen Handheld-Wireless Technology Co., Ltd. ndi bizinesi yapamwamba kwambiri padziko lonse lapansi yomwe ikuyang'ana kwambiri kafukufuku ndi chitukuko ndi kupanga zida za RFID zam'manja, zomwe zimapereka makonda a hardware ndi mapulogalamu a pulogalamu yogulitsira, mphamvu, ndalama, katundu, asilikali, apolisi. ndi zina.
