Doorka muhiimka ah ee anteenada RFID ee nidaamka RFID
Anteenada RFID waa nooc ka mid ah qalabka wax lagu beddelo, kaas oo beddesha hirarka la hago ee ku faafaya khadka gudbinta una beddela hirarka elektromagnetic-ka ee ku faafaya dhexdhexaadka aan xadka lahayn (badanaa booska xorta ah), ama sameeya isbeddelka lidka ku ah. Xubin gaar ah oo ka tirsan qoyska anteenada, anteenada RFID waxay door muhiim ah ka ciyaartaa nidaamka RFID:
Mabda'a shaqada ee anteenada RFID waxay ku salaysan tahay tiknoolajiyada isgaarsiinta raadiyaha, kaas oo anteenadu ay hesho oo ay ku faafto calaamadaha hirarka elektromagnetic-ka si loo xaqiijiyo akhrinta iyo qorista bilaa-waayirka ah ee macluumaadka ku kaydsan calaamadda. Gaar ahaan, anteenada RFID waa qalab gudbiya oo hela calaamadaha sideyaasha RF. Marka la eego shuruudaha ah in la go'aamiyo inta jeer ee hawlgalka iyo baaxadda, anteenadu waxay gudbisaa sideyaasha RF ee ay soo saarto module-ka habaynta RF waxayna heshaa sideyaasha RF ee laga soo saaro ama laga muujiyo calaamadda.
Calaamadahan sideyaasha RF waa aasaaska nidaamka RFID si loo xaqiijiyo aqoonsiga wireless-ka iyo is-weydaarsiga xogta.
Hawlaha ugu muhiimsan ee anteenada RFID waxaa inta badan ka mid ah:
Calaamadaha Gudbinta: Anteenada RFID waxay mas'uul ka tahay calaamadaha RF ee akhristaha soo saaro qaabka hirarka elektromagnetic-ka ee soo baxa. Calaamadahani waxay wataan tilmaamo iyo tamar gaar ah, oo loo isticmaalo in lagu dhaqaajiyo lana xiriiro Taag RFIDs. Nidaamka RFID ee soo noqnoqda oo kala duwan, anteenadu waxay gudbisaa hirarka calaamadda way ka duwan tahay. Naqshadeynta iyo waxqabadka anteenada ayaa si toos ah u saameeya xoogga iyo jihada calaamadaha la gudbiyo. Anteeno si fiican loo qaabeeyey ayaa calaamadda diiradda saari karta jiho gaar ah, iyadoo hagaajinaysa daboolida calaamadaha iyo hufnaanta gudbinta.
Hel calaamadaha: marka calaamadda RFID ay hesho calaamadda uu akhristuhu gudbiyo, waxay noqon doontaa iyada oo loo marayo anteenadeeda iyada oo ka jawaabi doonta calaamadda dib ugu celinaysa akhristaha. Anteenada RFID ayaa mas'uul ka ah helitaanka calaamadahan calaamadda, waxaana loo gudbin doonaa akhristaha si loo farsameeyo. Helitaanka xasaasiyadda anteenada iyo awoodda ka hortagga faragelinta si sax ah u helidda calaamadda calaamadda waa muhiim. Anteenada xasaasiga ah ee sare waxay heli kartaa calaamadaha calaamadda oo daciif ah, awoodda ka hortagga faragelinta wanaagsanna waxay yareyn kartaa faragelinta deegaanka ku xeeran, waxayna hagaajin kartaa tayada calaamadda.
Sida loo doorto anteenada RFID ee saxda ah
Xulashada anteenada RFID ee saxda ah waa tallaabo muhiim ah oo lagu hubinayo hawlgalka wax ku oolka ah ee nidaamka RFID. Kuwa soo socda waa xulashada Anteenooyinka RFID waxaa loo baahan yahay in la tixgeliyo qaar ka mid ah arrimaha:
1. xulashada soo noqnoqoshada
Nidaamyada RFID waxay caadi ahaan ku shaqeeyaan saddex qaybood oo soo noqnoqosho ah: soo noqnoqosho hoose (LF), soo noqnoqosho sare (HF) iyo soo noqnoqosho aad u sarreeya (UHF). Marka aad dooranayso anteeno, waa inaad marka hore go'aamisaa xadka soo noqnoqoshada ee nidaamkaaga RFID uu isticmaali doono.
2. Xaaladda Codsiga
Dooro anteeno ku salaysan xaaladda codsiga. Tusaale ahaan, haddii lagu isticmaalo bakhaar, waxaa laga yaabaa in loo baahdo anteeno akhris dheer; halka raadraaca alaabta yaryar, anteeno gaaban ayaa laga yaabaa inay ku habboon tahay.
3. Faa'iidada anteenada
Kobaca anteenada wuxuu saameeyaa xoogga calaamadda iyo masaafada akhriska. Anteenada faa'iidada sare leh waxay akhrin kartaa calaamadaha masaafada dheer, laakiin khariidadda jihada shucaaca ayaa laga yaabaa inay cidhiidhi noqoto; anteenada faa'iidada hoose leh waxay ku habboon tahay akhrinta dhow.
4. Nooca anteenada
Anteeno qorshaysan: ku habboon akhrinta calaamadaha walxaha fidsan.
Anteenada wareegga ah ee polarization: lagu dabaqi karo jihada calaamadda lama hubo, waxay hagaajin kartaa heerka guusha ee akhriska.
Anteeno toosan oo kala qaybsan: ku habboon jihada calaamadda la yaqaan.
5. Habka rakibidda
- Ka fiirso habka rakibidda anteenada (sida go'an, moobayl, ku dhex jira, iwm.), si loo hubiyo in anteenadu si wax ku ool ah uga shaqayn karto codsiga dhabta ah.
6. Arrimaha Deegaanka
Ka fiirso deegaanka lagu isticmaali doono anteenada (tusaale ahaan, heerkulka, qoyaanka, walxaha kiimikada, iwm.), oo dooro agab iyo naqshado ku habboon si loo hubiyo cimri dhererka anteenada.
7. Nooca Calaamadda
Noocyada kala duwan ee calaamadaha (tusaale ahaan calaamadaha aan firfircoonayn, calaamadaha firfircoon) waxay yeelan karaan shuruudo kala duwan oo anteenada ah. Hubi in anteenadu ay la jaanqaadi karto calaamadda la isticmaalayo.
8. Kala duwanaanshaha Akhriska
Xullo anteenada iyadoo loo eegayo masaafada akhriska ee loo baahan yahay, isticmaal anteeno gain sare leh si aad u akhrido masaafada dheer iyo anteeno gain hoose leh si aad u akhrido masaafada gaaban.
9.Kharashka
Dooro anteeno ku habboon miisaaniyaddaada. Anteenooyinka waxqabadka sare leh badanaa way qaali yihiin, laakiin waxay noqon karaan maalgashi lagama maarmaan ah oo ku saabsan codsiyada qaarkood.
Iyadoo la horumarinayo oo si xawli ah loo faafinayo tiknoolajiyadda internetka ee waxyaabaha, anteenada RFID oo qayb muhiim ah ka ah lakabka aragtida internetka ee waxyaabaha, nidaamka maaraynta hantida koodhka ee ugu horreeya sidoo kale wuxuu leeyahay boos aan la beddeli karin, hadda waxaa jira heerar iyo habraacyo kala duwan oo loogu talagalay tiknoolajiyadda RFID, kuwaas oo ilaa xad xaddidaya baaxadda codsigeeda. Mustaqbalka, iyadoo la raacayo qaan-gaarnimada joogtada ah ee tignoolajiyada iyo baahida suuqa, anteenada RFID waxaa la filayaa inay gaarto heeraynta iyo kor u qaadista iswaafajinta, yareyso heerka codsiga, kor u qaaddo caan-gelinta iyo codsiga tignoolajiyada RFID!
