Imvelaphi kunye nesicelo
Itekhnoloji yeRFID yitekhnoloji yokuchonga ezenzekelayo esekwe kwimiqondiso engenazingcingo kwaye ifanelekile kwiimeko ezahlukeneyo zosetyenziso. Ifumana ingqwalasela eyongezelelekileyo kumathala eencwadi, ulawulo lwamaxwebhu noovimba. Ngokongeza iilebhile ze-RFID kwiincwadi, amaxwebhu kunye noovimba, imisebenzi efana nokufunda ngokuzenzekelayo, umbuzo, ukubuyiswa kunye nokubuyisela kunokufezekiswa, ukuphucula ulawulo olusebenzayo kunye nenqanaba lenkonzo yezinto zoncwadi.
Kukho iindidi ezimbini eziphambili zeelebhile zeRFID ezisetyenziswa kumathala eencwadi kunye nolawulo lwamaxwebhu angoovimba, iilebhile zeRFID HF kunye neRFID UHF. Ezi lebhile zimbini zineempawu ezahlukileyo. Makhe ndihlalutye iiyantlukwano zabo ngezantsi:
Itekhnoloji yeRFID inokwahlulwa ibe ziindidi ezininzi ngokweendlela ezahlukeneyo zokusebenza: i-frequency ephantsi (LF), i-high frequency (HF), i-ultra high frequency (UHF) kunye ne-microwave (MW). Phakathi kwazo, i-frequency ephezulu kunye ne-ultra-high frequency zezona zimbini zisetyenziswa kakhulu iitekhnoloji zeRFID ngoku. Ngamnye kubo uneengenelo zabo kunye nemida, kwaye banokusebenza okwahlukileyo kwiimeko ezahlukeneyo.
Umgaqo osebenzayo: Itekhnoloji ye-RFID ye-high-frequency isebenzisa umgaqo we-inductive coupling ekufutshane nentsimi, oko kukuthi, umfundi uhambisa amandla kunye notshintshiselwano lwedatha kunye nethegi ngokusebenzisa intsimi yamagnetic. Itekhnoloji ye-UHF RFID isebenzisa umgaqo wokusasazeka kwemitha ye-electromagnetic ekude, oko kukuthi, umfundi uhambisa amandla kunye notshintshiselwano ngedatha kunye nethegi ngamaza ombane.
Uhlalutyo lokukhethwa kwemveliso
1. Iitshiphusi:I-HF incoma ukusebenzisa i-NXP ICODE SLIX chip, ehambelana neeprotocol ISO15693 kunye ne-ISO/IEC 18000-3 Mode 1. Inememori enkulu ye-EPC yeebhithi ze-1024, inokubhala kwakhona idatha amaxesha angama-100,000, kwaye inokugcina idatha ngaphezu kweminyaka eyi-10.
I-UHF incoma ukusebenzisa i-NXP UCODE 8, i-Alien Higgs 4, ihambelana nemigaqo ye-ISO 18000-6C kunye ne-EPC C1 Gen2, i-EPC, imemori ye-128 bit yomsebenzisi, enokuthi ibhale kwakhona idatha ngamaxesha angama-100,000, kwaye idatha ingagcinwa ngaphezu kwe-10 iminyaka.
2. Iimpondo: Ii-eriyali ze-HF zibhityile ngokwentelekiso, nto leyo enciphisa isiphumo sokuphazamiseka kokupakishwa kweethegi ezininzi. Amaza ombane anokudlulisa amandla athile kwiithegi ezisemva kwawo nge-eriyali. Zincinci kakhulu ngenkangeleko, ziphantsi ngexabiso, zigqwesile ekusebenzeni, kwaye zifihlakele kakhulu. Ke ngoko, iilebhile ze-HF zilungele ulawulo lweencwadi kunye neebhokisi zoovimba. Nangona kunjalo, ekulawuleni ifayile yephepha elinye, isetyenziselwa ubukhulu becala kwiifayile eziyimfihlo kakhulu, njengamaxwebhu aphezulu ayimfihlo, iifayile ezibalulekileyo zabasebenzi, imizobo yoyilo, kunye namaxwebhu ayimfihlo. Kukho iphepha elinye okanye ambalwa kwezi potifoliyo. Ukusebenzisa iithegi ze-HF kuya kuhambelana ngokusondeleyo, kubangela ukuphazamiseka okufanayo, okuchaphazela ukuchaneka kokuqaphela, kunye nokusilela ukuhlangabezana neemfuno zolawulo. Kule meko, kuyacetyiswa ukuba usebenzise isisombululo se-label ye-UHF.
3. Imathiriyeli engaphezulu: Zombini i-HF kunye ne-UHF zinokusebenzisa iphepha lobugcisa njengesixhobo somphezulu, kwaye zinokuprinta isicatshulwa esilungiselelweyo, iipateni okanye iibhakhowudi. Ukuba awudingi ukuprinta, ungasebenzisa inlay emanzi ngokuthe ngqo.
4. Iglu: Imeko yokusetyenziswa kweethegi idla ngokuncanyathiselwa ephepheni. Kulula ukunamathela kwaye indawo yokusetyenziswa ayinzima. I-adhesive eshushu eshushu ephantsi ngexabiso eliphantsi okanye iglu yamanzi ingasetyenziswa ngokuqhelekileyo.
5. Iphepha lokukhutshwa:Ngokuqhelekileyo, i-glassine-backed paper kunye ne-silicone oil layer isetyenzisiweyo, enganamathelisi kwaye yenza kube lula ukukrazula ithegi.
6. Uluhlu lokufunda: Itekhnoloji ye-HF RFID yitekhnoloji yokudibanisa ekufutshane nentsimi, kwaye uluhlu lwayo lokusebenza luncinci, ngokubanzi phakathi kweesentimitha ezili-10. Itekhnoloji ye-UHF RFID yitekhnoloji ye-electromagnetic radiation. I-electromagnetic wave inenqanaba elithile lokungena kwaye uluhlu lwalo lokusebenza lukhulu, ngokubanzi lungaphezulu kwemitha enye. Umgama wokufunda we-HF mncinane, ngoko unokukhangela ngokuchanekileyo iincwadi okanye iifayile zoovimba.
7. Isantya sokufunda: Ngenxa yokuthintelwa komgaqo-siseko wokudibanisa i-inductive, itekhnoloji ye-HF RFID inesantya esicothayo sokufunda kwaye kunzima ukufunda iithegi ezininzi ngaxeshanye. Ngenxa yeenzuzo zomgaqo wemitha ye-electromagnetic ekude, itekhnoloji ye-UHF RFID inesantya sokufunda esikhawulezayo kunye nomsebenzi wokufunda weqela. Itekhnoloji ye-UHF inomgama omde wokufunda kunye nesantya sokufunda ngokukhawuleza, ngoko iya kusebenza ngakumbi xa kuluhlu lweencwadi okanye iifayile.
8. Ikhono lokuchasana nokuphazamiseka: Ukudityaniswa kwe-inductive ekufutshane ne-high-frequency ye-RFID yetekhnoloji ye-RFID ye-high-frequency ye-high-frequency kunciphisa uphazamiseko olunokubakho ngaphandle kwamacingo, isenza itekhnoloji ye-high-frequency "ikhuseleke" kakhulu kwingxolo yokusingqongileyo kunye nokuphazamiseka kwe-electromagnetic interference (EMI), ngoko ke inamandla okuchasa uphazamiseko. . I-UHF isebenzisa umgaqo wokukhupha i-electromagnetic, ngoko ke ichaphazeleka lula kukuphazamiseka kombane. Ngelo xesha, isinyithi siya kubonakalisa iimpawu kunye namanzi angakwazi ukufumana iimpawu. Ezi zinto ziya kuphazamisana nomsebenzi oqhelekileyo weleyibhile Nangona ezinye izitikha ze-UHF emva kokuphuculwa kobuchwepheshe zinentsebenzo egqwesileyo ekuthinteleni ukuphazamiseka kwesinyithi kunye nolwelo, xa kuthelekiswa neeleyibhile ze-frequency ephezulu, i-UHF isengaphantsi kancinci, kwaye ezinye iindlela kufuneka zisetyenziswe lungisa oko.
9. Ukusetyenziswa kweelebhile ze-RFID ngokubambisana neetshaneli ezimilise umnyango kunye neesistim kunokuthintela ngokufanelekileyo ukulahleka kweencwadi kunye neefayile kunye nokuphumeza imisebenzi ye-alam yokususa engekho mthethweni.
Izisombululo ze-HF kunye ne-UHF RFID nganye ineenzuzo kunye nokungona kwayo, kwaye ukhetho kufuneka lulinganiswe kwaye luthelekiswe ngokusekelwe kwiimfuno kunye neemeko ezithile.
