I-antenna ye-RFID ekukhetheni nasekusebenziseni ulawulo lwezithuthi zothutho olukrelekrele

I-RFID luhlobo lobuchwepheshe bokuxilonga oluzenzekelayo olungenanxibelelwano, isebenzisa isignali yerediyo kunye nokudibanisa isithuba, uphawu lokudlulisela, lufezekisa ukuxilongwa ngokuzenzekelayo kwe-static okanye inqaku lentshukumo. Inkqubo ye-RFID idla ngokufundwa ngumfundi we-RFID, I-antenna ye-Rfid kunye neRFID RFID Tag enamacandelo amathathu. Isifundi seRFID nge-antenna sithumela isignali yerediyo, sivule iRFID Tag size sifunde kulwazi. Ithegi yeRFID idla ngokuncamathiselwa kwisithuthi, igcina uphawu olulodwa lwesithuthi kunye nolunye ulwazi oluhambelanayo.

Ukukhetha i-antenna yomfundi we-RFID ephezulu

I-antenna ye-RFID yinxalenye ebalulekileyo kwinkqubo ye-RFID, esetyenziselwa ukudlulisa isignali yerediyo, ukuqonda unxibelelwano phakathi komfundi kunye nethegi ye-RFID. Kulawulo lwezithuthi zothutho olukrelekrele, kubalulekile ukukhetha i-antenna ye-RFID efanelekileyo, kwaye kuyimfuneko ukuvavanya iiparameter zayo zokusebenza, kubandakanya i-gain, i-beadwidth, imo ye-polarization njalo njalo. I-Gain imisela ukugubungela isignali ye-antenna kunye nomgama wokufunda/ukubhala; i-beadwidth imisela uluhlu lokusasazwa kwe-electromagnetic wave ekhutshwa yi-antenna esibhakabhakeni; imo ye-polarization kufuneka ihambelane nemo ye-polarization ye-RFID Tag ukuqinisekisa isiphumo esingcono sokuhambisa isignali.

Xa ukhetha i-antenna ye-RFID, kufuneka uqwalasele ezi zinto zilandelayo:
1, indlela yokwahlukanisa: indlela yokwahlukanisa i-antenna kufuneka ihambelane nendlela yokwahlukanisa i-RFID tag ukuqinisekisa ukuba isiphumo sokudlulisa isignali singcono kakhulu. Kwindlela yokulawula umgca wemveliso yesithuthi, imeko yokufunda ngokulandelelana kweethegi ezikufutshane iyafana, iiprojekthi ezifanayo kwicala lokufaka i-tag ziyafana, ngoko ungakhetha i-antenna yokwahlukanisa umgca, i-antenna yokwahlukanisa umgca i-E-plane okanye i-H-plane beam angle ingenziwa ukuya kuma-30 degrees, ngoko ke i-radiation incinci kakhulu, isisombululo esihle kwingxaki yokufunda ngokulandelelana kweethegi ezikufutshane.

2, inzuzo ye-antenna: inzuzo ye-antenna luphawu olubalulekileyo lokusebenza kwe-antenna, luchaphazela ngqo umgama womfundi kunye nomgangatho wesignali. I-antenna ephezulu yokuzuza inokubonelela ngomgama omde wokufunda nokubhala kunye nokudluliselwa kwesignali okuzinzileyo, okusebenzayo kwimfuno yokuchongwa komgama omde kwendawo. Ekukhetheni i-antenna, kufuneka kusekelwe kwimfuno yokwenyani yokukhetha ixabiso elifanelekileyo lokuzuza, ngokuqhelekileyo umgama wokuzuza uphezulu, ukufunda nokubhala, kodwa kufuneka kuqwalaselwe ubungakanani kunye neendleko ze-antenna.

3, i-angle ye-beam: i-angle ye-beam imisela uluhlu lokusasazwa kwamaza e-electromagnetic akhutshwa yi-antenna esibhakabhakeni. Kulawulo lwezithuthi, ukuze kugqunywe indawo ebanzi, kudla ngokufuneka kukhethwe i-antenna ene-angle ye-beam ebanzi. Nangona kunjalo, kwiindawo ezifuna ukuchongwa ngokuchanekileyo, njengolawulo lokufikelela kwisithuthi, kunokufuneka kukhethwe i-antenna ene-angle ye-beam encinci ukunciphisa ukuphazamiseka kunye nokutolikwa gwenxa.

4, indawo yokusebenza: indawo yokusebenza inempembelelo ebalulekileyo ekusebenzeni kwe-antenna. Kulawulo lwesithuthi, i-antenna inokufuna ukuba ivezwe kwindawo yangaphandle, ngoko ke kufuneka ukhethe i-antenna engangeni manzi, engangeni luthuli, engangeni manzi kubushushu obuphezulu kunye nezinye iimpawu ukuqinisekisa ukusebenza kwayo okuzinzileyo ixesha elide.

I-antenna ye-RFID kwisicelo solawulo lwezithuthi zothutho olukrelekrele
Kulawulo lwezithuthi zothutho olukrelekrele, i-antenna ye-RFID ineendlela ezahlukeneyo zokusetyenziswa kunye neenzuzo ezibalulekileyo. Nazi ezinye zeemeko eziqhelekileyo zokusetyenziswa:

1, ulawulo lokufikelela kwisithuthi: ngokufaka i-antenna ye-RFID kunye nomfundi kwindawo yokupaka okanye kwi-port yekhadi lethrafikhi, inokufezekisa ulawulo olukhawulezileyo lokungena nokuphuma kwezithuthi. Xa izithuthi zidlula kwindawo yokufunda, i-antenna inokufunda ulwazi olukwi-RFID Tag yezithuthi ukusuka kumgama omde, kwaye igwebe ubuwena bezithuthi kunye negunya ngokuzenzekelayo, ngaloo ndlela ilawula isango lokuvula nokuvala. Le ndlela ayiphuculi nje kuphela ukufikelela kwezithuthi ekusebenzeni kakuhle, kodwa ikwanciphisa ukungenelela ngesandla kunye nomngcipheko wokungasebenzi kakuhle.

2, ulawulo lokupaka olukrelekrele: kwindawo yokupaka, iteknoloji ye-RFID inokuphumeza ukuhlawuliswa ngokuzenzekelayo, ukuvulwa nokuvalwa kwesango ngokuzenzekelayo kunye neminye imisebenzi. Izithuthi eziya kwindawo yokupaka, i-antenna ye-RFID kunye nomfundi ziya kuchonga ngokuzenzekelayo ulwazi lwesithuthi kwaye zirekhode ixesha lokupaka; hamba, inkqubo ye-RFID iya kubala ngokuzenzekelayo iindleko kwaye ihlawule ngokupheleleyo ngokwexesha lokupaka. Oku akuphuculi nje kuphela ukusebenza kakuhle kwendawo yokupaka, kodwa kukwaphucula kakhulu amava omsebenzisi.

3, ukulandelela nokuthumela izithuthi: kwicandelo lezothutho lwezothutho kunye nezothutho lukawonke-wonke, itekhnoloji ye-RFID ingasetyenziselwa ukulandelela nokuthumela izithuthi. Ngokufaka ii-RFID Tags kwizithuthi kunye nokufaka ii-antenna zokufunda kwiindawo eziphambili, ulwazi lwendawo kunye nesimo sezithuthi lunokufunyanwa ngexesha langempela. Olu lwazi lungasetyenziselwa ukuphucula indlela yokuthutha, ukuphucula ukusebenza kakuhle kwezothutho, ukunciphisa izinga elingenanto kunye nokusetyenziswa kwepetroli.

4, ukuqokelelwa kwedatha yetrafikhi kunye nohlalutyo: ngokudityaniswa kwezinzwa kunye nemodyuli yokufumana idatha kwi-antenna yokufunda i-RFID, ukuqokelelwa kwedatha yetrafikhi ngexesha langempela, njengokuhamba kwesithuthi, isantya, indlela yokuhamba, njl.njl. Le datha ingasetyenziselwa ucwangciso lwetrafikhi, isilumkiso sangaphambi kwexesha sokuxinana, uhlalutyo lweengozi, njl.njl., ukubonelela ngesiseko sesayensi kunye nenkxaso yokwenza izigqibo kwisebe lolawulo lwetrafikhi.

5, ukujonga ukhuseleko lwezithuthi: ekujongeni ukhuseleko lwezithuthi, iteknoloji ye-RFID ingasetyenziselwa ukulandelela nokubeka izithuthi ezibiweyo. Ngokufunda ulwazi olukwithegi ye-RFID yezithuthi ezibiweyo, kwaye zidityaniswe ne-GIS (inkqubo yolwazi lwejografi) kunye ne-GPS (inkqubo yehlabathi yokubeka) kunye nezinye iiteknoloji, inokufezekisa ukulandelela nokubeka izithuthi ezibiweyo ngexesha langempela, iphucule ukusebenza kakuhle kunye nezinga lempumelelo lokubuyiselwa kwezithuthi.
