I-antenna ye-RFID ekukhetheni nasekusebenziseni ukuphathwa kwezimoto zokuhamba ezihlakaniphile

I-RFID uhlobo lobuchwepheshe bokuxilonga okuzenzakalelayo okungathintani, isebenzisa isignali yemvamisa yomsakazo kanye nokuxhumanisa isikhala, isici sokudlulisa, sifinyelela ekuxilongweni okuzenzakalelayo kwe-static noma kwe-movement article. Uhlelo lwe-RFID ngokuvamile lusetshenziswa ngumfundi we-RFID, I-Antenna ye-Rfid kanye ne-RFID RFID Tag enezingxenye ezintathu. umfundi we-RFID nge-antenna uthumela isignali yemvamisa yomsakazo, asebenze i-RFID Tag futhi afunde kulwazi. I-RFID tag ivame ukunamathiselwa emotweni, igcina ukuhlonza okuhlukile kwemoto nolunye ulwazi oluhlobene.

Ukukhetha i-antenna yomfundi we-RFID ephezulu

I-antenna ye-RFID iyisici esibalulekile ohlelweni lwe-RFID, esetshenziselwa ukudlulisa isignali yemvamisa yomsakazo, ukuqaphela ukuxhumana phakathi komfundi nethegi ye-RFID. Ekuphathweni kwezimoto zokuthutha ezihlakaniphile, kubalulekile ukukhetha i-antenna ye-RFID efanelekile, futhi kuyadingeka ukuhlola amapharamitha ayo okusebenza, okuhlanganisa i-gain, i-beadwidth, imodi ye-polarization nokunye. I-Gain inquma ukumbozwa kwesignali ye-antenna kanye nebanga lokufunda/ukubhala; i-beadwidth inquma ububanzi bokusatshalaliswa kwegagasi le-electromagnetic elikhishwa yi-antenna esikhaleni; imodi ye-polarization idinga ukufaniswa nemodi ye-polarization ye-RFID Tag ukuqinisekisa umphumela omuhle kakhulu wokudlulisa isignali.

Ekukhetheni i-antenna ye-RFID, kudingeka ucabangele izici ezilandelayo ezibalulekile:
1, isiqondiso se-polarization: isiqondiso se-polarization se-antenna kufanele sihambisane nesiqondiso se-polarization se-tag ye-RFID ukuqinisekisa umphumela omuhle kakhulu wokudlulisa isignali. Ekuphathweni komugqa wokukhiqiza wemoto kuvame ukuhlangana nesimo sokufunda okulandelanayo kwamathegi aseduze, amaphrojekthi afanayo esiqondisweni sokufakwa kwamathegi ngokuyisisekelo afanayo, ngakho-ke ungakhetha i-antenna ye-polarization yomugqa, i-antenna ye-polarization yomugqa i-E-plane noma i-H-plane beam angle ingenziwa kuma-degree angu-30, ngakho-ke imisebe incane kakhulu, ikhambi elihle lenkinga yokufunda okulandelanayo kwamathegi aseduze.

2, inzuzo ye-antenna: inzuzo ye-antenna iyinkomba ebalulekile yokusebenza kwe-antenna, ithinta ngqo ibanga lomfundi kanye nekhwalithi yesignali. I-antenna enenzuzo ephezulu inganikeza ibanga elide lokufunda nokubhala kanye nokudluliswa kwesignali okuzinzile, okusebenza ngesidingo sokuhlonza ibanga elide lendawo. Ekukhetheni i-antenna, kufanele kusekelwe esidingweni sangempela sokukhetha inani elifanele lenzuzo, ngokuvamile lapho inzuzo iphakama, ibanga lokufunda nokubhala, kodwa futhi kudingeka kucatshangelwe usayizi nezindleko ze-antenna.

3, i-angle ye-beam: i-angle ye-beam inquma ububanzi bokusatshalaliswa kwamagagasi kagesi akhishwa yi-antenna esikhaleni. Ekuphathweni kwezimoto, ukuze kuhlanganiswe indawo ebanzi, ngokuvamile kudingeka ukhethe i-antenna ene-angle ye-beam ebanzi. Kodwa-ke, ngezigcawu ezidinga ukuhlonza okunembile, njengokulawula ukufinyelela kwemoto, kungadingeka ukhethe i-antenna ene-angle ye-beam encane ukuze kuncishiswe ukuphazamiseka kanye nokuchazwa kabi.

4, indawo yokusebenza: indawo yokusebenza inomthelela obalulekile ekusebenzeni kwe-antenna. Ekuphathweni kwezimoto, i-antenna kungadingeka ukuthi ivezwe endaweni engaphandle, ngakho-ke udinga ukukhetha i-antenna enezici ezingangeni manzi, ezingangeni uthuli, ezingangenisi izinga lokushisa eliphezulu kanye nezinye izici ukuqinisekisa ukusebenza kwayo okuzinzile isikhathi eside.

I-antenna ye-RFID kuhlelo lokusebenza lokuphathwa kwezimoto zokuhamba ezihlakaniphile
Ekuphathweni kwezimoto zokuthutha ezihlakaniphile, i-antenna ye-RFID inezinhlobo eziningi zezimo zokusetshenziswa kanye nezinzuzo ezibalulekile. Nazi ezinye zezimo zokusetshenziswa ezivamile:

1, ukulawula ukufinyelela kwezimoto: ngokufaka i-antenna ye-RFID kanye ne-reader endaweni yokupaka noma echwebeni lekhadi lethrafikhi, ingaqaphela ukulawula okusheshayo kokungena nokuphuma kwezimoto. Lapho izimoto zidlula indawo yokufunda, i-antenna ingafunda ulwazi oluku-RFID Tag yezimoto lukude, futhi yahlulele ubunikazi bezimoto kanye negunya ngokuzenzakalelayo, ngaleyo ndlela ilawula isango lokuvula nokuvala. Ngale ndlela ayigcini nje ngokuthuthukisa ukufinyelela kwezimoto ekusebenzeni kahle, kodwa futhi inciphisa ukungenelela ngesandla kanye nengozi yokusebenza kabi.

2, ukuphathwa kokupaka okuhlakaniphile: endaweni yokupaka, ubuchwepheshe be-RFID bungafeza ukukhokhisa okuzenzakalelayo, ukuvulwa nokuvalwa kwesango okuzenzakalelayo kanye neminye imisebenzi. Izimoto eziya endaweni yokupaka, i-antenna ye-RFID kanye nomfundi kuzobona ngokuzenzakalelayo ulwazi lwemoto bese ziqopha isikhathi sokupaka; hamba, uhlelo lwe-RFID luzobala ngokuzenzakalelayo izindleko futhi luqedele inkokhelo ngokwesikhathi sokupaka. Lokhu akugcini nje ngokuthuthukisa ukusebenza kahle kwendawo yokupaka, kodwa futhi kuthuthukisa kakhulu ulwazi lomsebenzisi.

3, ukulandelela nokuthumela izimoto: emkhakheni wezokuthutha nezokuthutha zomphakathi, ubuchwepheshe be-RFID bungasetshenziswa ekulandeleni nasekuthumeleni izimoto. Ngokufaka amathegi e-RFID ezimotweni nokufaka ama-antenna abafundi ezindaweni ezibalulekile, ulwazi lwendawo nesimo sezimoto lungatholakala ngesikhathi sangempela. Lolu lwazi lungasetshenziswa ukwenza ngcono umzila wokuthutha, ukuthuthukisa ukusebenza kahle kwezokuthutha, ukunciphisa izinga elingenalutho kanye nokusetshenziswa kukaphethiloli.

4, ukuqoqwa nokuhlaziywa kwedatha yethrafikhi: ngokuhlanganiswa kwezinzwa kanye nemodyuli yokuthola idatha ku-antenna yokufunda i-RFID, ukuqoqwa kwedatha yethrafikhi ngesikhathi sangempela, njengokugeleza kwemoto, isivinini, indlela yokuhamba, njll. Le datha ingasetshenziswa ekuhleleni ithrafikhi, isexwayiso sangaphambi kwesikhathi sokuminyana, ukuhlaziywa kwezingozi, njll., ukuhlinzeka ngesisekelo sesayensi kanye nokusekelwa kokwenza izinqumo emnyangweni wokuphathwa kwethrafikhi.

5, ukuqapha ukuphepha kwezimoto: ekuqapheni ukuphepha kwezimoto, ubuchwepheshe be-RFID bungasetshenziswa ekulandeleni nasekubekeni izimoto ezebiwe. Ngokufunda ulwazi olusethegini le-RFID yezimoto ezebiwe, futhi kuhlanganiswe ne-GIS (uhlelo lolwazi lwendawo) kanye ne-GPS (uhlelo lokubeka umhlaba wonke) kanye nobunye ubuchwepheshe, kungafeza ukulandelela nokubeka izimoto ezebiwe ngesikhathi sangempela, kuthuthukise ukusebenza kahle kanye nezinga lempumelelo lokubuyiselwa kwezimoto.
