Omanyi enkola y'emirimu gya RFID reader?

RFID radio frequency identification kwe kukozesa leediyo okutambuza signals, eziyinza okutegeera obutakwatagana na-okukwatagana kw’amawulire. Enkola ya RFID okusobola okukola mu ngeri eya bulijjo, yeetaaga waakiri ebitundu bibiri: akabonero k’ebyuma n’omusomi. Taagi y’ebyuma (electronic tag) ye data carrier w’enkola ya radio frequency identification system. Kikolebwa antenna ya tag ne tag-specific chip. RFID reader kye kyuma ekikulu eky’okusoma data.

RFID reader ewuliziganya ku waya ne RFID electronic tag okuyita mu (reader) antenna, era esobola okusoma oba okuwandiika tag identification code ne memory data. Omusomi owa bulijjo alimu modulo ya waggulu-Frequency (transmitter ne receiver), ekitundu ekifuga, ne antenna eri omusomi.

RFID Reader Entambula y'emirimu .

Ekifo (non-kikwatagana) Okuyunga kwa siginiini ya leediyo kwa leediyo kutegeerekeka okuyita mu kintu ekiyunga wakati w’akabonero k’ebyuma n’omusomi. Mu mukutu gw’okuyunga, okutambuza amaanyi n’okuwanyisiganya amawulire bituukirira okusinziira ku nkolagana y’obudde. Okumanya enkola endala ez’enkola z’enkola za RFID, laba ekiwandiiko: Enkola y’emirimu gy’enkola za RFID eri etya

Enkola y’emirimu gy’omusomi wa RFID ng’eweereza ebiragiro:

.

.

3. Data epakibwa mu serial baseband signal era esindikibwa ku RF front-End module.

.

5. Oluvannyuma lw’okusengejja, siginiini esindikibwa ku amplifier y’amasannyalaze okusobola okugaziya, n’oluvannyuma n’esindikibwa ku antenna okufuna okutambuza.

 

Enkola y'emirimu gy'omusomi wa RFID okufuna amawulire agakwata ku data ya tag backscatter:

1. RFID electronic tag efuna signal okuva eri omusomi, efuna amaanyi era ekolebwa power-ku, etandika okukola ekiragiro ky’omusomi, era esala omusango oba eky’okuddamu kyetaagisa. Bwe kyetaagisa okuddamu, amawulire g’okuddamu gayisibwa mu antenna mu ngeri esaasaanidde emabega. Esindikiddwa ku RF mu maaso-End module.

2. RF front-End module esindika signal efunibwa ku band-Pass filter for filtering. Oluvannyuma lw’okusengejja, siginiini y’omutwala ekomezebwawo ku siginiini ya baseband n’eyisibwa okuyita mu low-noise amplifier, down-okukyusa, okukyusa n’ebitundu ebirala.

3. Data esindikibwa ku baseband processing module mu PC okuyita mu interface.
