Indima ebalulekile ye-antenna ye-RFID ohlelweni lwe-RFID

I-Antenna ye-Rfid uhlobo lokuguqula, oluguqula igagasi eliqondiswayo elisakazeka emgqeni wokudlulisa libe yigagasi likagesi elisakazeka endaweni engenamingcele (ngokuvamile isikhala esikhululekile), noma lenze ushintsho oluphambene. Njengelungu elikhethekile lomndeni we-antenna, i-antenna ye-RFID idlala indima ebalulekile ohlelweni lwe-RFID:

Isimiso sokusebenza se-antenna ye-RFID sisekelwe kubuchwepheshe bokuxhumana ngomsakazo, lapho i-antenna ithola futhi ikhiphe khona izimpawu zamagagasi kagesi ukuze kufezwe ukufundwa nokubhalwa okungenantambo kolwazi olugcinwe kuthegi. Ngokukhethekile, i-antenna ye-RFID iyidivayisi edlulisa futhi yamukele izimpawu ze-RF carrier. Ngaphansi kwesimo sokuthi imvamisa yokusebenza kanye ne-bandwidth kunqunywa, i-antenna idlulisa isithwali se-RF esikhiqizwe yi-RF processing module futhi ithole isithwali se-RF esikhishwa noma esiboniswa kuthegi.

Lezi zimpawu ze-RF carrier ziyisisekelo sohlelo lwe-RFID ukuze kutholakale ukuhlonza okungenantambo kanye nokushintshana kwedatha.

Imisebenzi eyinhloko ye-antenna ye-RFID ifaka phakathi:

Izimpawu zokudlulisa: I-antenna ye-RFID inesibopho sezibonakaliso ze-RF ezikhiqizwa umfundi ngesimo samaza kagesi akhishwayo. Lezi zibonakaliso ziphethe imiyalelo ethile namandla, asetshenziselwa ukwenza kusebenze futhi kuxhunyaniswe ne- Ithegi ye-Rfids. Uhlelo lwe-RFID oluhlukile lwemvamisa, i-antenna idlulisela ubude be-wavelength yesiginali buhlukile. Ukwakheka nokusebenza kwe-antenna kuthinta ngqo amandla kanye nokuqondisa kwezibonakaliso ezidlulisiwe. I-antenna eklanywe kahle ingagxila isiginali ohlangothini oluthile, ithuthukise ukumbozwa kwesiginali kanye nokusebenza kahle kokudlulisa.

Thola izimpawu: uma ithegi ye-RFID ithola isignali edluliselwa ngumfundi, izophendula isignali nge-antenna yayo ibuyele kumfundi. I-antenna ye-RFID inesibopho sokwamukela lezi zimpawu ezivela kuthegi, futhi izodluliselwa kumfundi ukuze icutshungulwe. I-antenna ethola ukuzwela kanye nekhono lokulwa nokuphazamiseka ukuze ithole isignali yethegi ngokunembile kubalulekile. I-antenna ezwela kakhulu ingathola izimpawu zethegi ezibuthakathaka, futhi ikhono elihle lokulwa nokuphazamiseka linganciphisa ukuphazamiseka okuvela endaweni ezungezile, lithuthukise ikhwalithi yesignali.

Indlela yokukhetha i-antenna ye-RFID efanele

Ukukhetha i-antenna ye-RFID efanele kuyisinyathelo esibalulekile ekuqinisekiseni ukusebenza kahle kohlelo lwe-RFID. Okulandelayo ukukhetha kwe Ama-antenna e-Rfid kudingeka sicabangele ezinye zezici:

1. Ukukhetha imvamisa

Izinhlelo ze-RFID zivame ukusebenza ngamabhendi amathathu emvamisa: imvamisa ephansi (LF), imvamisa ephezulu (HF) kanye nemvamisa ephezulu kakhulu (UHF). Uma ukhetha i-antenna, kufanele uqale unqume ukuthi iyiphi ibhendi yemvamisa ezosetshenziswa uhlelo lwakho lwe-RFID.

2. Isimo Sesicelo

Khetha i-antenna ngokusekelwe esimweni sohlelo lokusebenza. Isibonelo, uma isetshenziswa endaweni yokugcina impahla, i-antenna yokufunda ibanga elide ingadingeka; ngenkathi kulandelwa izinto ezincane, i-antenna yebanga elifushane ingafaneleka kakhulu.

3. Ukwanda kwe-antenna

Ukwanda kwe-antenna kuthinta amandla esignali kanye nebanga lokufunda. I-antenna ekhuphuka kakhulu ingafunda amathegi ebangeni elide, kodwa imephu yesiqondiso semisebe ingase ibe mincane; i-antenna ekhuphuka kancane ifanelekela ukufundwa eduze.

4. Uhlobo lwe-Antenna

I-antenna ehleliwe: ifanele ukufunda amathegi ezintweni eziyisicaba.

I-antenna ye-polarization eyindilinga: ayiqiniseki ukuthi isebenza kanjani esiqondisweni selebula, ingathuthukisa izinga lempumelelo lokufunda.

I-antenna yokwehlukanisa ngomugqa: ifanelekela isiqondiso selebula esaziwayo.

5. Indlela yokufaka

-Cabanga ngendlela yokufaka i-antenna (njenge-fixed, mobile, embedded, njll.), ukuqinisekisa ukuthi i-antenna ingasebenza kahle kuhlelo lokusebenza lwangempela.

6. Izici zemvelo

Cabanga ngendawo lapho kuzosetshenziswa khona i-antenna (isib. izinga lokushisa, umswakama, amakhemikhali, njll.), bese ukhetha izinto zokwakha nemiklamo efanele ukuqinisekisa ukuqina kwe-antenna.

7. Uhlobo lwethegi

Izinhlobo ezahlukene zamathegi (isb. amathegi angasebenzi, amathegi asebenzayo) zingase zibe nezidingo ezahlukene ze-antenna. Qiniseka ukuthi i-antenna iyahambisana nethegi esetshenziswayo.

8. Uhla Lokufunda

Khetha i-antenna ngokwebanga lokufunda elidingekayo, sebenzisa i-antenna ethola inzuzo ephezulu ekufundeni ibanga elide kanye ne-antenna ethola inzuzo ephansi ekufundeni ibanga elifushane.

9. Izindleko

Khetha i-antenna efanela isabelomali sakho. Ama-antenna asebenza kahle kakhulu ngokuvamile abiza kakhulu, kodwa angaba utshalomali oludingekayo kwezinye izinhlelo zokusebenza.

Ngokuthuthuka okusheshayo kanye nokuthandwa kobuchwepheshe be-inthanethi yezinto, i-antenna ye-RFID njengengxenye ebalulekile yengqimba yokubona ye-inthanethi yezinto, ohlelweni lokuphathwa kwempahla lwekhodi lokuqala lunesikhundla esingenakuguqulwa, njengamanje kunezindinganiso ezahlukahlukene kanye nezinqubo zobuchwepheshe be-RFID, ezikhawulela ububanzi bokusetshenziswa kwayo ngezinga elithile. Esikhathini esizayo, ngokuvuthwa okuqhubekayo kobuchwepheshe kanye nesidingo semakethe, i-antenna ye-RFID kulindeleke ukuthi ifinyelele ekulinganisweni nasekuthuthukisweni kokuhambisana, inciphise umkhawulo wohlelo lokusebenza, ikhuthaze ukuthandwa kanye nokusetshenziswa kobuchwepheshe be-RFID!
