Amathegi e-RFID electronic manje asetshenziswa kabanzi ekuphathweni kwempahla, ukulandelela izinto, ukulandeleka kokudla, ukuphathwa kwempahla neminye imikhakha.
Njengamanje, ama-chips amathegi e-UHF RFID asetshenziswa kabanzi emakethe ahlukaniswe izigaba ezimbili: angenisiwe nasekhaya, afaka Ikakhulu i-IMPINJ, ALIEN, NXP, Kiloway, njll.
1. I-Alien (USA)
Esikhathini esedlule, ithegi ye-Alien's RFID tag H3 (igama eligcwele: Higgs 3) nayo yayidume kakhulu.Kuze kube manje, le chip isetshenziswe kumaphrojekthi amaningi wangaphambilini.Indawo yokugcina enkulu ingenye yezinzuzo zayo ezisobala.
Nokho, ngokuvela kwezinhlelo zokusebenza ezintsha ezihlukahlukene kanye nezidingo eziphakeme neziphakeme zebanga lokufunda lamathegi emikhakheni emisha, kancane kancane kuba nzima ukuthi ukuzwela kokufunda kwe-H3 kuhlangabezane nezidingo.I-Alien iphinde yabuyekeza futhi yathuthukisa ama-chips ayo, futhi kamuva kwaba khona i-H4 (Higgs 4), H5 (Higgs EC), kanye ne-H9 (Higgs 9).
Ama-chips akhishwe yi-Alien azoba nemigqa yenguqulo yomphakathi yamasayizi ahlukahlukene kanye nezinhlelo zokusebenza.Lokhu kubanikeza inzuzo enkulu ekukhangiseni ama-chips abo kanye nokuhlala emakethe.Amakhasimende amaningi kanye nabaphakathi bangathola ngokuqondile omaka ukuze basetshenziswe isilingo, okunciphisa isikhathi nezindleko zokuthuthukisa izinti zamathegi.
Ngenxa yokuthi i-impedance yama-chips e-H9 ne-H3 iyafana, futhi indlela yokubopha yamaphinikhodi nayo iyafana, i-antenna yomphakathi ye-H3 yangaphambilini ingaxhunyaniswa ngokuqondile ne-H9.Amakhasimende amaningi asebenzise i-chip ye-H3 ngaphambilini angasebenzisa i-chip entsha ngokuqondile ngaphandle kokushintsha uthi, okubalondolozela izinto eziningi.Izinhlobo zomugqa zakudala: ALN-9710, ALN-9728, ALN-9734, ALN-9740, ALN-9662, njll.
2. Impinj (USA)
Ama-chips e-Impinj's UHF aqanjwe ngochungechunge lwe-Monza.Kusukela ku-M3, M4, M5, M6, ibuyekezwe yaba kweyakamuva i-M7.Kukhona futhi uchungechunge lwe-MX, kodwa isizukulwane ngasinye singase sibe nezingaphezu kwesisodwa.
Isibonelo, uchungechunge lwe-M4 luhlanganisa: M4D, M4E, M4i, M4U, M4QT.Lonke uchungechunge lwe-M4 luyi-chip ye-dual-port, engasetshenziswa njengelebula le-dual-polarization, ukugwema isimo sokuthi ilebula ye-polarization yomugqa kanye nesiphambano se-antenna polarization efundwayo akukwazi ukufundwa, noma ibanga lokufunda lokunciphisa i-polarization liseduze. .Kuhle ukusho ukuthi umsebenzi we-QT we-chip ye-M4QT cishe uhlukile kuyo yonke insimu, futhi unezindlela ezimbili zokugcina idatha yomphakathi neyimfihlo, enokuphepha okuphezulu.
Ama-chips ochungechunge olufanayo ahluke kakhulu ekuhlukaniseni indawo yesitoreji nosayizi, futhi i-impedance yawo, indlela yokubopha, usayizi we-chip, nokuzwela kuyefana, kodwa amanye awo azoba nemisebenzi emisha.Ama-chips we-Impinj awavamile ukushintshwa ngezibuyekezo, futhi isizukulwane ngasinye sinamaphuzu aso acwebezelayo kanye nokungabuyiseleki kwenye indawo.Ngakho kuze kuvele uchungechunge lwe-M7, i-M4 ne-M6 zisathatha imakethe enkulu.Ezivame kakhulu emakethe yi-M4QT ne-MR6-P yazo, futhi manje sekune-M730 ne-M750 eyandayo.
Sekukonke, ama-chips e-Impinj abuyekezwa njalo, ukuzwela kuya ngokuya kuya phezulu, futhi usayizi we-chip uya uba mncane futhi ube mncane.Uma i-chip ye-Impinj yethulwa, kuzophinde kube nokukhishwa kohlobo lomugqa osesidlangalaleni kohlelo lokusebenza ngalunye.Izinhlobo zolayini zakudala zifaka: H47, E61, AR61F, njll.
3. I-NXP (Netherlands)
Uchungechunge lwe-Ucode lwe-NXP lwama-chip tag e-UHF asetshenziswa kakhulu ekudayiseni izingubo, ukuphathwa kwezimoto, ukuvikelwa komkhiqizo neminye imikhakha.Isizukulwane ngasinye salolu chungechunge lwama-chips siqanjwe ngokuya ngohlelo lokusebenza, amanye awo ayivelakancane emakethe ngenxa yezinkambu zawo zokufaka izicelo ezincane.
Izizukulwane ze-U7, U8, kanye ne-U9 ochungechungeni lwe-Ucode yizona ezisetshenziswa kakhulu.Futhi njenge-Impinj, isizukulwane ngasinye se-NXP sine-chip engaphezu kweyodwa.Isibonelo: U7 uhlanganisa i-Ucode7, Ucode7m, Ucode 7Xm-1k, Ucode 7xm-2K, Ucode 7xm+.Amabili okuqala azwela kakhulu, inkumbulo encane.Amamodeli amathathu okugcina anenkumbulo enkulu kanye nokuzwela okuphansi kancane.
I-U8 kancane kancane ingene esikhundleni se-U7 (ngaphandle kwama-memory chips amathathu amakhulu e-U7xm) ngenxa yokuzwela kwayo okuphezulu.I-chip ye-U9 yakamuva nayo iyathandwa, futhi ukuzwela kokufunda kufinyelela ngisho -24dBm, kodwa isitoreji siba sincane.
Ama-chips e-NXP ajwayelekile agxile kakhulu ku-: U7 kanye ne-U8.Iningi lezinhlobo zomugqa welebula ziklanywe abakhiqizi abanamakhono e-R&D ngelebula, futhi kunezinguqulo ezimbalwa zomphakathi ezibonwayo.
Lokhu kungase kube umkhuba ojwayelekile wokuthuthukiswa kwe-chip tag ye-RFID emhlabeni:
1. Ubukhulu be-chip buba buncane, ukuze ama-wafer amaningi angakhiqizwa ngosayizi ofanayo, futhi okukhiphayo kukhuphuka kakhulu;
2. Ukuzwela kuya ngokuya kukhula, futhi manje okuphezulu kakhulu sekufinyelele ku--24dBm, okungahlangabezana nezidingo zamakhasimende zokufunda ibanga elide.Isetshenziswa emikhakheni eminingi futhi inganciphisa nenani lamadivayisi okufunda afakiwe kuhlelo lokusebenza olufanayo.Kumakhasimende wokugcina, ukonga izindleko zesixazululo sisonke.
3. Inkumbulo iba yincane, okubonakala kuwukuzidela okufanele kwenziwe ukuthuthukisa ukuzwela.Kodwa amakhasimende amaningi awadingi inkumbulo eningi, adinga kuphela ukwenza amakhodi azo zonke izinto angaphindaphindiwe, nolunye ulwazi lwento ngayinye (njengokuthi: yakhiqizwa nini, ikuphi, lapho iphuma efektri. , njll.) ingafaniswa ngokuphelele ohlelweni olurekhodwe ngamakhodi, futhi akudingekile ukubhala konke kukhodi.
Njengamanje, i-IMPINJ, ALIEN, kanye ne-NXP ithatha ingxenye enkulu yemakethe ye-chip yenjongo evamile ye-UHF.Laba bakhiqizi benze izinzuzo zesikali emkhakheni wama-chips enhloso ejwayelekile.Ngakho-ke, ezinye izidlali ze-chip tag ze-UHF RFID zenzelwe ukuthuthukiswa okukhethekile okwenziwe ngokwezifiso kwezinkundla zohlelo, Phakathi kwabakhiqizi basekhaya, i-Sichuan Kailuwei ithuthuke ngokushesha uma kuqhathaniswa nalokhu.
4. Sichuan Kailuway (China)
Esimeni lapho imakethe yethegi ye-RFID isicishe yagcwala, i-Kailuwei ivule umkhondo ngokuthembela kubuchwepheshe benkumbulo obungapheli obuzithuthukisile be-XLPM obunamandla aphansi.Noma yimaphi ama-chips ochungechunge lwe-Kailuwei's X-RFID anemisebenzi yawo eyisici.Ikakhulukazi, uchungechunge olukhethekile lwe-KX2005X lunokuzwela okuphezulu nenkumbulo enkulu, okuyivelakancane emakethe, futhi lunemisebenzi yokukhanyisa kwe-LED, ukutholwa kokucisha, kanye nemisebe elwa nokwelashwa.Ngama-LED, uma amathegi esetshenziswa ekuphathweni kwefayela noma ekuphathweni komtapo wolwazi, ungathola ngokushesha amafayela owafunayo nezincwadi ngokukhanyisa ama-LED, okuthuthukisa kakhulu ukusebenza kahle kosesho.
Kubikwa ukuthi baphinde bethula uchungechunge lokufunda kuphela lwama-minimalist: OKU-1 KUPHELA kanye no-2 KUPHELA, okungathathwa njengokuqanjwa okusha kuma-tag chips e-RFID.Yephula i-stereotype yokuhlukaniswa kwelebula ye-chip, ishiya umsebenzi wokubhala kabusha ilebula, futhi ilungise ngokuqondile ikhodi yelebula lapho iphuma efekthri.Uma ikhasimende lingadingi ukushintsha ikhodi yelebula kamuva, ukusebenzisa le ndlela kuzocishe kuqede ukulingisa amalebula omgunyathi, ngoba ikhodi ngayinye yelebula ihlukile.Uma efuna ukulingisa, udinga ukuqala nge-wafer ye-custom chip, futhi izindleko zokwenziwa komgunyathi ziphezulu kakhulu.Lolu chungechunge, ngaphezu kwezinzuzo zokulwa nokukhwabanisa okukhulunywe ngenhla, ukuzwela kwalo okuphezulu kanye nezindleko eziphansi kungabhekwa "njengokuphela" emakethe.
Ngaphezu kwabakhiqizi be-chip tag be-RFID UHF bethulwe ngenhla, kukhona futhi i-em microelectronic (EM microelectronics eSwitzerland, i-chip yabo ye-dual-frequency chip ingeyokuqala emhlabeni, futhi ingumholi wama-chips ama-dual-frequency), i-Fujitsu (eJapane Fujitsu), Fudan (Shanghai Fudan Microelectronics Group), CLP Huada, National Technology njalonjalo.
I-Shenzhen Handheld-Wireless Technology Co., Ltd iyinhlangano kazwelonke yobuchwepheshe obuphezulu egxile ocwaningweni nasekuthuthukisweni nasekukhiqizweni kwemishini yokugcina ephathwa ngesandla ye-RFID, ehlinzeka ngezinsizakusebenza ezenziwe ngokwezifiso nesoftware yezitolo, amandla, ezezimali, ezokuthutha, amasosha, amaphoyisa. njll.
