Indima ebalulekileyo ye-antenna ye-RFID kwinkqubo ye-RFID

I-antenna ye-Rfid luhlobo lwe-converter, eguqula i-wave ekhokelwayo esasazeka kumgca wothumelo ibe yi-electromagnetic wave esasazeka kwi-medium engenamda (ihlala ikhululekile), okanye yenza utshintsho oluchaseneyo. Njengelungu elikhethekileyo losapho lwe-antenna, i-antenna ye-RFID idlala indima ebalulekileyo kwinkqubo ye-RFID:

Umgaqo osebenzayo we-antenna ye-RFID usekelwe kubuchwepheshe bonxibelelwano lwerediyo, apho i-antenna ifumana kwaye isasaze imiqondiso yamaza e-electromagnetic ukuze ifezekise ukufundwa nokubhalwa kolwazi olugcinwe kwithegi. Ngokukodwa, i-antenna ye-RFID sisixhobo esithumela kwaye sifumana imiqondiso ye-RF carrier. Phantsi kwemeko yokuba i-frequency yokusebenza kunye ne-bandwidth zimiselwe, i-antenna ithumela i-RF carrier eyenziwe yi-RF processing module kwaye ifumana i-RF carrier ekhutshwa okanye eboniswa kwithegi.

Ezi zimpawu zokuthwala zeRF zisisiseko senkqubo yeRFID ukuze kufezekiswe ukuchonga okungenazingcingo kunye nokutshintshiselana ngedatha.

Imisebenzi ephambili ye-antenna ye-RFID ibandakanya ikakhulu:

Imiqondiso yokudlulisa: I-antenna ye-RFID inoxanduva lwemiqondiso ye-RF eveliswa ngumfundi ngendlela yamaza e-electromagnetic akhutshwayo. Ezi miqondiso ziphethe imiyalelo ethile kunye namandla, asetyenziselwa ukwenza kusebenze kwaye kunxibelelane Ithegi ye-Rfids. Inkqubo ye-RFID ye-frequency eyahlukileyo, i-antenna idlulisela ubude be-signal wavelength yahlukile. Uyilo kunye nokusebenza kwe-antenna kuchaphazela ngokuthe ngqo amandla kunye necala lemiqondiso edluliselweyo. I-antenna eyilwe kakuhle ingagxila isignali kwicala elithile, iphucula ukugubungela isignali kunye nokusebenza kakuhle kokudlulisela.

Imiqondiso yokwamkela: xa ithegi ye-RFID ifumana isignali edluliselwa ngumfundi, iya kuba nge-antenna yayo iya kuphendula kwisignali ibuyele kumfundi. I-antenna ye-RFID inoxanduva lokufumana ezi mpawu kwithegi, kwaye iya kudluliselwa kumfundi ukuze icutshungulwe. I-antenna efumana uvakalelo kunye nokukwazi ukulwa nokuphazamiseka ukuze ifumane isignali yethegi ngokuchanekileyo kubalulekile. I-antenna enovakalelo oluphezulu ingafumana imiqondiso yethegi ebuthathaka, kwaye amandla amahle okulwa nokuphazamiseka anokunciphisa ukuphazamiseka okuvela kwindawo engqongileyo, aphucule umgangatho wesignali.

Indlela yokukhetha i-antenna ye-RFID efanelekileyo

Ukukhetha i-antenna ye-RFID efanelekileyo linyathelo elibalulekileyo ekuqinisekiseni ukusebenza kakuhle kwenkqubo ye-RFID. Oku kulandelayo kukukhetha Ii-antenna ze-Rfid kufuneka siqwalasele ezinye zezi zinto:

1.ukhetho lwefrikhwensi

Iinkqubo zeRFID zihlala zisebenza kwiibhendi ezintathu zefrikhwensi: ifrikhwensi ephantsi (LF), ifrikhwensi ephezulu (HF) kunye nefrikhwensi ephezulu kakhulu (UHF). Xa ukhetha i-antenna, kufuneka uqale umisele ukuba yeyiphi ifrikhwensi eya kusetyenziswa yinkqubo yakho yeRFID.

2. Imeko yesicelo

Khetha i-antenna ngokusekelwe kwimeko yesicelo. Umzekelo, ukuba isetyenziswa kwindawo yokugcina izinto, i-antenna yokufunda umgama omde ingafuneka; ngelixa kulandelelwa izinto ezincinci, i-antenna yomgama omfutshane ingafaneleka ngakumbi.

3. Ukwanda kwee-antenna

Ukwanda kwe-antenna kuchaphazela amandla esignali kunye nomgama wokufunda. I-antenna efumana i-high gain ingafunda iithegi kumgama omde, kodwa imephu yendlela yokukhanya inokuba mncinci; i-antenna efumana i-low gain ifanelekile ukufundwa kufutshane.

4. Uhlobo lwe-antenna

I-antenna ejikelezileyo: ifanelekile ukufunda iithegi kwizinto ezithe tyaba.

I-antenna ye-polarization ejikelezayo: ayiqinisekanga ukuba isebenza kwicala leleyibhile, inokuphucula izinga lempumelelo yokufunda.

I-antenna ye-polarization ethe tyaba: ifanelekile kwicala elaziwayo leelebheli.

5. Indlela yokufaka

-Cinga ngendlela yokufaka i-antenna (efana ne-fixed, mobile, embedded, njl.njl.), ukuqinisekisa ukuba i-antenna ingasebenza ngokufanelekileyo kwisicelo sokwenyani.

6. Izinto ezisingqongileyo

Cinga ngendawo eza kusetyenziswa kuyo i-antenna (umz., ubushushu, ukufuma, iikhemikhali, njl.njl.), kwaye ukhethe izixhobo ezifanelekileyo kunye noyilo ukuqinisekisa ukuqina kwe-antenna.

7. Uhlobo lwethegi

Iintlobo ezahlukeneyo zeethegi (umz. iithegi ezingasebenziyo, iithegi ezisebenzayo) zinokuba neemfuno ezahlukeneyo ze-antenna. Qinisekisa ukuba i-antenna iyahambelana nethegi esetyenziswayo.

8. Uluhlu lokufunda

Khetha i-antenna ngokomgama ofunekayo wokufunda, sebenzisa i-antenna ephezulu yokufunda umgama omde kunye ne-antenna ephantsi yokufunda umgama omfutshane.

9. Ixabiso

Khetha i-antenna ehambelana nohlahlo lwabiwo-mali lwakho. Ii-antenna ezisebenza kakuhle zihlala zibiza kakhulu, kodwa zisenokuba lutyalo-mali oluyimfuneko kwezinye iinkqubo.

Ngophuhliso olukhawulezileyo kunye nokwanda kweteknoloji ye-Intanethi yezinto, i-antenna ye-RFID njengenxalenye ebalulekileyo yomaleko wokuqonda we-Intanethi yezinto, kwinkqubo yolawulo lweeasethi yekhowudi yokuqala ikwanayo indawo engenakutshintshwa, okwangoku kukho imigangatho eyahlukeneyo kunye neenkqubo zobuchwepheshe be-RFID, nto leyo ethintela umda wesicelo sayo ukuya kwinqanaba elithile. Kwixesha elizayo, ngokuvuthwa okuqhubekayo kweteknoloji kunye nemfuno yemarike, i-antenna ye-RFID kulindeleke ukuba ifikelele kwimigangatho kunye nokuphucula ukuhambelana, inciphise umda wesicelo, ikhuthaze ukwanda kunye nokusetyenziswa kweteknoloji ye-RFID!
