Iithegi ze-elektroniki ze-RFID ngoku zisetyenziswa ngokubanzi kulawulo lwesitora, ukulandelela izinto, ukulandeleka kokutya, ulawulo lwe-asethi kunye neminye imimandla.
Okwangoku, iitshiphusi zethegi ze-UHF RFID ezisetyenziswa ngokubanzi kwimarike zohlulwe zibe ziindidi ezimbini: ezingeniswa kumazwe angaphandle kunye nezasekhaya, zibandakanya ikakhulu IMPINJ, ALIEN, NXP, Kiloway, njl.
1. Alien (USA)
Ngaphambili, i-Alien's RFID tag chip H3 (igama elipheleleyo: Higgs 3) nayo yayidume kakhulu.Ukuza kuthi ga ngoku, le chip isetyenziswe kwiiprojekthi ezininzi zangaphambili.Indawo enkulu yokugcina enye yeenzuzo zayo ezicacileyo.
Nangona kunjalo, ngokuvela kwezicelo ezitsha ezahlukeneyo kunye neemfuno eziphezulu neziphakamileyo zomgama wokufunda weethegi kwiindawo ezintsha, kuba nzima kancinci ukuba uvakalelo lokufunda lwe-H3 luhlangabezane neemfuno.I-Alien iphinde yahlaziywa kwaye yaphucula iitshiphusi zabo, kwaye kamva kwakukho i-H4 (i-Higgs 4), i-H5 (i-Higgs EC), kunye ne-H9 (i-Higgs 9).
Iichips ezikhutshwe yi-Alien ziya kuba nemigca yenguqulelo yoluntu yobukhulu obahlukeneyo kunye nokusetyenziswa.Oku kubanika inzuzo enkulu ekukhuthazeni iitshiphusi zabo kunye nokuhlala kwimarike.Abathengi abaninzi kunye nabaphakathi banokufumana ngokuthe ngqo iithegi zokusetyenziswa kolingo, okunciphisa ixesha kunye neendleko zokuphuhlisa ii-eriyali zethegi.
Ngenxa yokuba i-impedance ye-chips ye-H9 kunye ne-H3 iyafana, kwaye indlela yokudibanisa i-chip pin nayo iyafana, i-antenna yoluntu ye-H3 yangaphambili inokudibaniswa ngokuthe ngqo kwi-H9.Abathengi abaninzi abasebenzisa i-chip ye-H3 ngaphambili banokusebenzisa i-chip entsha ngokuthe ngqo ngaphandle kokutshintsha i-eriyali, egcina izinto ezininzi kubo.Iindidi zomgca we-Alien classic: ALN-9710, ALN-9728, ALN-9734, ALN-9740, ALN-9662, njl.
2. Impinj (USA)
Iitshiphusi zika-Impinj ze-UHF zithiywe ngothotho lwe-Monza.Ukusuka ku-M3, M4, M5, M6, ihlaziywe yaya kutsho kwi-M7 yamva nje.Kukwakho nothotho lwe-MX, kodwa isizukulwana ngasinye sinokuba nangaphezulu kwesinye.
Ngokomzekelo, uluhlu lwe-M4 lubandakanya: M4D, M4E, M4i, M4U, M4QT.Uluhlu olupheleleyo lwe-M4 yi-chip ye-double-port, enokusetyenziswa njengeleyibhile ye-polarization ephindwe kabini, ukuthintela imeko yokuba ileyibhile ye-polarization yomgca kunye ne-antenna efundwayo ye-polarization cross ayikwazi ukufundwa, okanye i-polarization attenuation umgama wokufunda usondele. .Kuyafaneleka ukukhankanya ukuba umsebenzi we-QT we-chip ye-M4QT uphantse uyingqayizivele kwintsimi yonke, kwaye ineendlela ezimbini zokugcina idatha yoluntu kunye nedatha yangasese, enokhuseleko oluphezulu.
Iichips zoluhlu olufanayo zihluke kakhulu kwindawo yokugcina kunye nobukhulu, kunye ne-impedance yazo, indlela yokubopha, ubungakanani be-chip, kunye novakalelo ziyafana, kodwa ezinye zazo ziya kuba nemisebenzi emitsha.Iichips ze-Impinj azifane zitshintshwe ngohlaziyo, kwaye isizukulwana ngasinye sineendawo zaso ezikhazimlayo kunye nokungabinandawo.Ngoko de kuvele uchungechunge lwe-M7, i-M4 kunye ne-M6 isahlala kwimarike enkulu.Eyona nto ixhaphakileyo kwimarike yi-M4QT kunye ne-MR6-P, kwaye ngoku kukho i-M730 kunye ne-M750 eninzi.
Lilonke, iichips ze-Impinj zihlaziywa rhoqo, ubuntununtunu buba phezulu nangaphezulu, kwaye ubungakanani be-chip buba buncinci kwaye buncinci.Xa i-chip ye-Impinj isungulwa, kuya kubakho ukukhutshwa kohlobo lwelayini yoluntu kwisicelo ngasinye.Iindidi zomgca weClassic ziquka: H47, E61, AR61F, njl.
3. I-NXP (eNetherlands)
Uluhlu lwe-Ucode ye-NXP yee-tag chips ze-UHF zisetyenziswa ngokubanzi kwiintengiso zempahla, ulawulo lwezithuthi, ukukhuselwa kophawu kunye nezinye iinkalo.Isizukulwana ngasinye solu ngcelele lweetshiphusi sithiywe ngokwesicelo, ezinye zazo zinqabile kwimarike ngenxa yeendawo zazo ezincinci zesicelo.
Izizukulwana ze-U7, U8, kunye ne-U9 kuthotho lwe-Ucode zezona zisetyenziswa kakhulu.Kwakhona njenge-Impinj, isizukulwana ngasinye se-NXP sine-chip engaphezulu kwesinye.Umzekelo: I-U7 iquka i-Ucode7, i-Ucode7m, i-Ucode 7Xm-1k, i-Ucode 7xm-2K, i-Ucode 7xm +.Ezokuqala ezimbini zinovakalelo oluphezulu, inkumbulo encinci.Iimodeli ezintathu zokugqibela zinememori enkulu kunye novakalelo olusezantsi kancinci.
I-U8 ithe chu kancinci yathatha indawo ye-U7 (ngaphandle kwee-memory chips ezintathu ezinkulu ze-U7xm) ngenxa yobuntununtunu obuphezulu.I-chip ye-U9 yamva nje iyathandwa, kwaye ubuntununtunu bokufunda bude bufikelele -24dBm, kodwa ugcino luba luncinci.
Iitshiphusi ze-NXP eziqhelekileyo zigxininiswe kakhulu kwi-: U7 kunye ne-U8.Uninzi lweentlobo zomgca weleyibhile ziyilwe ngabavelisi abaneleyibhile ye-R&D isakhono, kwaye zimbalwa iinguqulelo zoluntu ezibonwayo.
Oku kunokuba yindlela eqhelekileyo yophuhliso lwetshiphu yethegi yeRFID kwihlabathi:
1. Ubungakanani be-chip buba buncinci, ukuze ii-wafers ezininzi ziveliswe ngobukhulu obufanayo, kwaye imveliso iyanda kakhulu;
2. Uvakalelo luba phezulu kwaye luphezulu, kwaye ngoku iphezulu ifikelele -24dBm, enokuthi ihlangabezane neemfuno zabathengi bokufunda ixesha elide.Isetyenziswa kwiinkalo ezininzi kwaye inokunciphisa inani lezixhobo zokufunda ezifakiweyo kwisicelo esifanayo.Kubathengi bokugqibela, ukugcina ixabiso lesisombululo esipheleleyo.
3. Inkumbulo iba yincinci, ebonakala ngathi idini elimele lenziwe ukuphucula uvakalelo.Kodwa abathengi abaninzi abayidingi imemori eninzi, kufuneka benze kuphela iikhowudi zazo zonke izinto ezingaphinda-phindwayo, kunye nolunye ulwazi lwento nganye (ezifana nokuba: xa yaveliswa, apho ibikhona, xa ishiya umzi-mveliso. njl.
Okwangoku, i-IMPINJ, ALIEN, kunye ne-NXP zithatha uninzi lwe-UHF yenjongo jikelele ye-chip market.Aba bavelisi benze izibonelelo zesikali kwintsimi yeetshiphusi ezinenjongo ngokubanzi.Ke ngoko, abanye abadlali be-tag ye-UHF RFID balungiselelwe uphuhliso olukhethekileyo lwemimandla yesicelo, Phakathi kwabavelisi basekhaya, iSichuan Kailuwei iphuhlise ngokukhawuleza kule nkalo.
4. Sichuan Kailuway (eTshayina)
Kwimeko apho imakethi yethegi yeRFID iphantse yagcwala, iKailuwei iye yavutha umkhondo ngokuthembela kwitekhnoloji yememori esisigxina ye-XLPM yamandla asezantsi.Nayiphi na chips series Kailuwei X-RFID has imisebenzi yayo uphawu.Ngokukodwa, uchungechunge olukhethekileyo lwe-KX2005X lunovakalelo oluphezulu kunye nenkumbulo enkulu, enqabileyo kwimarike, kwaye inemisebenzi yokukhanyisa kwe-LED, ukufumanisa ukucinywa, kunye nemitha yokuchasana nonyango.Ngee-LED, xa iithegi zisetyenziselwa ulawulo lwefayile okanye ulawulo lwamathala eencwadi, unokufumana ngokukhawuleza iifayile ezifunwayo kunye neencwadi ngokukhanyisa ii-LED, eziphucula kakhulu ukusebenza kakuhle kokukhangela.
Kuxelwe ukuba baye basungula uthotho lwe-minimalist yokufunda-kuphela kweetshiphusi: KUPHELA i-1 kunye ne-2 KUPHELA, enokuthi ithathwe njengento entsha kwiitshiphusi zethegi zeRFID.Iphula i-stereotype yokwahlula kweleyibhile yokugcina i-chip, ishiya umsebenzi wokubhala kwakhona ileyibhile, kwaye ilungisa ngokuthe ngqo ikhowudi yeleyibhile xa iphuma kumzi-mveliso.Ukuba umthengi akadingi ukuguqula ikhowudi yeleyibhile kamva, ukusebenzisa le ndlela kuya phantse kuphelise ukuxelisa iilebhile zomgunyathi, kuba ikhowudi yeleyibhile nganye yahlukile.Ukuba ufuna ukuxelisa, kufuneka aqale nge-wafer yesiko le-chip, kwaye iindleko zomgunyathi ziphezulu kakhulu.Olu chungechunge, ngaphezu kweenzuzo ezichasene ne-counterfeiting ezikhankanywe ngasentla, uvakalelo lwalo oluphezulu kunye neendleko eziphantsi zinokuthathwa ngokuba "kuphela" kwimarike.
Ukongeza kwi-RFID UHF abavelisi be-chip tag baziswa ngasentla, kukwakho ne-em microelectronic (EM microelectronics eSwitzerland, i-chip yabo ephindwe kabini yeyokuqala emhlabeni, kwaye iyinkokeli yeetshiphusi eziphindwe kabini), iFujitsu (eJapan. Fujitsu) , Fudan (i-Shanghai Fudan Microelectronics Group), i-CLP Huada, iTekhnoloji yeSizwe kunye nokunye.
I-Shenzhen Handheld-Wireless Technology Co., Ltd. lishishini lesizwe lobugcisa obuphezulu obugxile kuphando kunye nophuhliso kunye nokuveliswa kwezixhobo ze-RFID eziphathwa ngesandla, ezibonelela ngehardware kunye neenkonzo zesoftware zokuthengisa, amandla, imali, izixhobo, umkhosi, amapolisa. njl.
