Yazisa indima yokufunxa izinto kwithegi ye-RFID yesinyithi

Ithegi ye-RFID yesinyithi esichasene nesinyithi, ikwabizwa ngokuba yi-uhf RFID Ithegi yokuchasa isinyithi, ziithegi ze-elektroniki ezenziwe ngezinto ezifunxayo ezinemisebenzi yokulwa nokuphazamiseka. Zisombulula ngempumelelo ingxaki yabathwali besinyithi abaphazamisana nemiqondiso yerediyo yeethegi ze-elektroniki ezinamathele kumphezulu wazo.

Kwiithegi ze-RFID zesinyithi kunye nezinto ezifunxayo zineempawu ezilandelayo:

1. Abasebenzisi besinyithi Ithegi ye-Rfidbanokwenza ngokwezifiso ukufundwa kwedatha yabo esemgangathweni ukuphucula ukusebenza kakuhle kwenkqubo yesicelo;

2. Iithegi zeRFID ezifakelwe ngentsimbi zinomgama omde wokufunda (umgama wokufunda nokubhala unxulumene nomfundi weRFID kunye ne-antenna);

3. Amandla okulwa nokuphazamiseka anamandla kakhulu;

4. Ixesha elide lokugcina idatha, ukuya kuthi ga kwiminyaka engama-20, ukusebenza ngexabiso eliphezulu;

5. Ukufundwa kweethegi ezininzi akuchaphazeleki okanye akuthintelwanga linani leethegi kwindawo yokusebenza;

6. Iithegi zeRFID zeendawo zesinyithi zamkela uyilo lwebhendi yokusebenza ebanzi kakhulu, engapheleli nje ekuthobeleni imigaqo efanelekileyo yoshishino, kodwa inokuphuhliswa nokusetyenziswa ngokuguquguquka;

7. Indawo yokugcina izinto yenzelwe abasebenzisi ukuba benze imisebenzi yokufunda, ukubhala, ukucima kunye nokubhala ngokutsha ngokufihlakeleyo, kwaye ingachaza nendawo yamagama esisigxina enikezelwe kubasebenzisi.
Ngokuphuhliswa kwe-Intanethi yezinto, ukusetyenziswa kwezinto ezifunxayo kwiithegi zeRFID ngoku kuqheleke kakhulu. Ithegi yesinyithi ye-UHF ikwasetyenziswa kwiindawo ezahlukeneyo, kuquka ulawulo lwezinto ezisetyenziswayo, ulawulo lweendawo zokugcina impahla, ulawulo lweeasethi nakwezinye iindawo. Ngoko ke yintoni indima yokufunxa izinto kwithegi yesinyithi ye-uhf?

Kwi-RFID frequency range, xa amaza e-electromagnetic edibana nomphezulu wesinyithi, ngenxa ye-eddy current phenomenon, kuveliswa ukubonakaliswa kwamaza e-electromagnetic anamandla, kwaye kukho umahluko wesigaba phakathi kwamaza e-electromagnetic abonakalisiweyo kunye namaza esiganeko, nto leyo ebangela ukurhoxiswa kwamacala omabini. Ngeli xesha, intsimi ye-electromagnetic esebenzayo ngokwenene iyancipha ngokukhawuleza, kuba okukhona i-resistivity yesixhobo sesinyithi iphantsi, kokukhona ilahleko yamandla e-eddy iya kuba nkulu, kwaye kokukhona ingxaki yesinyithi ibangelwa yingozi. Ke ngoko, xa i-antenna iphantsi kokuphazamiseka okukhulu kwesinyithi, imiyalelo ekhutshwe ngumfundi wekhadi iya kunyamalala ngokupheleleyo, ngoko ke isiphumo sokufunda idatha siyasilela. Izinto ezifunxayo zisebenzisa ikakhulu ipropathi ephezulu ye-magnetic permeability. Xa isetyenziswa, iphepha lokufunxa lifakwa phakathi kwe-antenna ejikelezayo ye Ithegi yesinyithi ye-uhf RFID kunye ne-substrate yesinyithi, eyonyusa amathuba okuba intsimi yemagnethi ebangelwayo idlule kwizinto ezifunxayo ngokwayo kwaye inciphise amathuba okudlula kwipleyiti yesinyithi, ngaloo ndlela inciphisa umsinga we-eddy obangelwayo owenziwe kwipleyiti yesinyithi. Izinto ezifunxayo zinciphisa ngakumbi ukulahleka kwentsimi yemagnethi ebangelwayo. Kwangaxeshanye, ngenxa yokufakwa kwephepha lokuzihlukanisa lemagnethi ebangelwayo, umthamo we-parasitic olinganisiweyo nawo uya kuncitshiswa, kwaye i-frequency offset iya kuncitshiswa, ehambelana ne-resonant frequency yomfundi wekhadi, ngaloo ndlela iphucula kakhulu isiphumo sokufunda ikhadi kunye nomgama.

Eyona ndlela iphambili yokusebenzisa iimpawu eziphezulu ze-magnetic permeability zezinto ezifunxayo kukufaka iphepha lokufunxa phakathi Ithegi yesinyithi ye-uhf RFIDI-antenna emile okwesibuko kunye ne-substrate yesinyithi, yonyusa amathuba okuba intsimi yemagnethi ebangelwayo idlule kwizinto ezifunxayo ngokwayo kwaye inciphise amathuba okudlula kwipleyiti yesinyithi, ngaloo ndlela inciphisa umsinga we-eddy obangelwayo owenziwe kwipleyiti yesinyithi, kwaye izinto ezifunxayo zinciphisa ngakumbi ukulahleka kwentsimi yemagnethi ebangelwayo. Kwangaxeshanye, ngenxa yokufakwa kwephepha lokuzahlula lemagnethi ebangelwayo, umthamo we-parasitic olinganisiweyo nawo uya kuncitshiswa, i-frequency offset iya kuncitshiswa, kwaye iya kuhambelana ne-resonance frequency yomfundi wekhadi, ngaloo ndlela iphucula kakhulu isiphumo sokufunda ikhadi kunye nomgama.

Ezinye iiprojekthi ebomini ziya kudibana neendawo ezahlukeneyo, ezifana namaqondo obushushu aphezulu naphantsi, ulwelo, iindonga zesamente, amandla ombane aqinileyo, isinyithi, njl.

Umzekelo, kwindawo yesinyithi, kwinkqubo ye-ultra-high frequency identification tag (UHF) radio frequency identification tag, kunzima kakhulu ukuchonga ii-tag ezinamathele kwi-metal carriers kuba imiqobo yesinyithi iya kubonakalisa kwaye iphazamise amaza e-electromagnetic. Okwangoku, kukho iindlela ezine zokusombulula ngempumelelo ingxaki yokubamba ulwazi kumphezulu wesinyithi:

1. Sebenzisa izinto ezifunxayo ukuze ufunxe amaza e-electromagnetic agqithisileyo;

2. Uyilo lobude bephedi;

3. I-bandwidth ye-antenna yethegi kufuneka yanele;

4. Uyilo lwe-antenna olusekelwe phantsi.

Okwangoku, indlela yethu eqhelekileyo kukusebenzisa izinto zokufunxa kunye nokuphakama kwephedi ngokudibeneyo. Indlela efanelekileyo kukuyila i-antenna ene-bandwidth enkulu size sisebenzise izinto zokufunxa ukuphakama kwephedi, nto leyo eya kufezekisa isiphumo esihle kakhulu.
