Yadda RFID ke Aiki

Mai karatu yana aika takamaiman siginar RF na mitar ta hanyar eriya mai watsawa, wanda shine ainihin ƙa'idar aiki na tsarin RFID. Lokacin da tambarin lantarki ya shiga wurin aiki mai inganci, ana samar da wutar lantarki don samun kuzari da kunna shi, yana barin alamar lantarki ta watsa bayanan da aka ɓoye ta hanyar ginanniyar eriya; eriyar mai karantawa tana karɓar siginar da aka daidaita da aka aiko daga tag ɗin, wanda ake aikawa zuwa tsarin sarrafa siginar mai karatu ta hanyar na'urar sarrafa eriya. Ana watsa bayanai masu tasiri zuwa tsarin watsa shirye-shiryen baya don aiki mai dacewa bayan an lalata shi kuma an tsara shi; Tsarin rundunar yana ƙayyade ainihin alamar ta amfani da ayyuka masu ma'ana, sa'an nan kuma yayi aiki mai dacewa da sarrafawa don saitunan daban-daban kafin aika sigina don sarrafa mai karatu don kammala ayyukan karatu da rubutu daban-daban.

 

Ana iya raba tsarin RFID zuwa inductive coupling (Magnetic coupling) da tsarin na'urorin haɗi na lantarki (electromagnetic coupling) dangane da sadarwa da fahimtar makamashi tsakanin alamun lantarki da masu karatu. Dangane da ka'idar shigar da wutar lantarki, tsarin haɗaɗɗiyar inductive yana haifar da babban filin mu'amala da maganadisu a sarari; Haɗin kai na baya-bayan nan na lantarki, wanda kuma aka sani da tsarin ƙa'idar radar, yana fitar da igiyoyin lantarki waɗanda ke nunawa lokacin da suka ci karo da manufa kuma suna mayar da bayanan manufa.

Tsarin RFID yana da tsarin aiki na asali, wanda ke nuna cewa tsarin RFID yana amfani da mitar rediyo mara igiyar waya don aiwatar da watsa bayanan da ba a haɗa tsakanin masu karatu da alamun lantarki ba, yana ba da damar gano manufa, watsa bayanai, da sarrafawa. Gabaɗayan aikin tsarin RFID shine kamar haka:

1. Mai karatu yana watsa siginar RF a takamaiman mitar ta amfani da eriya mai watsawa.

2. Lokacin da alamar lantarki ta shiga wurin aiki na eriyar mai karatu, eriyar alamar lantarki tana haifar da isassun ƙarfin halin yanzu don kunna ƙarfin da aka samu ta alamar lantarki.

3. Alamar lantarki tana watsa bayanan nata ta hanyar eriya da aka gina a ciki.

4. Ana karɓar siginar ɗauka ta eriyar mai karatu daga alamar lantarki.

5. Ana isar da siginar mai ɗauka zuwa ga mai karatu ta eriyar mai karantawa.

6. Mai karatu/marubuci yana ragewa da yanke siginar da aka karɓa kafin tura shi zuwa babban tsarin{1}} don sarrafawa.
