Enyanjula mu RFID Reader n'Entambula y'Emirimu .

RFID radio frequency identification ekozesa leediyo okutambuza signals era esobola okutuuka ku non-Okutegeera amawulire okutuukirira. Okukakasa nti enkola ya RFID ekola bulungi, yeetaaga okussaamu waakiri ebitundu bibiri: akabonero k’ebyuma n’omusomi/omuwandiisi. Taagi y’ebyuma (electronic tag) ye data carrier y’enkola ya RFID, erimu tag antenna ne tag specific chip. RFID Reader/Writer kye kyuma ekikulu eky'okusoma data. Ka tulabe enkola y’emirimu gy’omusomi n’omuwandiisi wa RFID.

 

1. Tekinologiya wa RFID kye ki .

RFID radio frequency identification is a non-Contact automatic identification technology ezuula ebintu ebigendererwa mu ngeri ey’otoma era n’efuna data ekwatagana okuyita mu bubonero bwa leediyo. Omulimu gw‟okuzuula tekyetaagisa kuyingirira mu ngalo era gusobola okukola mu mbeera ez‟enjawulo enkambwe.

Tekinologiya wa RFID asobola okutegeera ebintu ebitambula eby’amaanyi- ate mu kiseera kye kimu n’ategeera tags eziwera, ekifuula okukola okw’amangu era okwangu. Short range RF products tezitya mbeera nkambwe nga amafuta g’amafuta n’obucaafu bw’enfuufu, era zisobola okukyusa bbaakoodi mu mbeera ng’ezo, gamba ng’okulondoola ebintu ku layini z’amakolero. Ebintu ebikolebwa mu leediyo eby’ewala bitera okukozesebwa mu ntambula, nga waliwo amabanga agamanyibwa okutuuka ku makumi g’amakumi, gamba ng’okukung’aanya omusolo mu ngeri ey’otoma oba okuzuula mmotoka.

 

2. Enkola za RFID .

Enkola ya RFID erimu waakiri ebitundu bibiri: akabonero k’ebyuma n’omusomi/omuwandiisi. Okusinziira ku nkola ez’enjawulo ez’okugabira amasannyalaze mu bipande by’amasannyalaze, tags ez’amasannyalaze zisobola okwawulwamu tags ezikola, passive tags, ne semi&passive tags. Active electronic tag eriko bbaatule, ate nga passive RF tag terina bbaatule ya munda. Semi&passive tag ekitundu kyesigamye ku bbaatule okukola.

Ebipande by’amasannyalaze bisobola okwawulwamu obubonero obutono obw’ebyuma, ebiwanvu-Ebiwandiiko eby’amasannyalaze ebya frequency, ultra-ebipande by’amasannyalaze ebya frequency eya waggulu, n’ebipande by’amasannyalaze ebya microwave nga byesigamiziddwa ku firikwensi ez’enjawulo. Okusinziira ku foomu ez’enjawulo ez’okupakinga, esobola okugabanyizibwamu ebiwandiiko bya kaadi z’okuwola, ebiwandiiko ebiriko ennyiriri, ebiwandiiko by’empapula, ebiwandiiko ebiwandiikiddwa ku ttanka y’endabirwamu, ebiwandiiko ebyekulungirivu, n’ebiwandiiko ebitali bituufu eby’ekigendererwa eky’enjawulo.

RFID reader ewuliziganya ku waya ne RFID electronic tags okuyita mu antenna, okusobozesa okusoma oba okuwandiika tag identification codes ne memory data. Omusomi/omuwandiisi owa bulijjo alimu modulo za waggulu-Frequency (transmitter ne receiver), ebitundu ebifuga, ne antenna z’omusomi/omuwandiisi.

 

3. RFID Reader/Omuwandiisi Enkola y'emirimu .

Okuyunga obubonero bwa RF mu kifo (obutakwatagana) wakati wa tag z’ebyuma n’ebisomi kutuukirizibwa okuyita mu bitundu ebiyunga. Mu mukutu gw’okuyunga, okutambuza amaanyi n’okuwanyisiganya amawulire bituukibwako nga byesigamiziddwa ku nkolagana ey’ekiseera. Entambula z’emirimu eziwera ku nkola za RFID, enkola z’emirimu ku nkola za RFID ze ziruwa .

 

Enkola y'emirimu gy'omusomi/omuwandiisi wa RFID ng'aweereza 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 okutambuza.

 

Enkola y’emirimu gy’omusomi wa RFID ng’efuna amawulire agakwata ku biwandiiko eby’emabega:

1. RFID electronic tag efuna signal okuva mu reader, efuna amaanyi, era ekola nga power ON. Kitandika okutuukiriza ekiragiro ky'omusomi era ne kisalawo oba eky'okuddamu kyetaagisa. Bwe kiba kyetaagisa okuddamu, amawulire g’okuddamu gasindikibwa ku RF mu maaso-End module okuyita mu antenna mu ngeri ya backscatter.

2. RF front-End module esindika signal efunibwa ku bandpass filter okusengejja. Oluvannyuma lw’okusengejja, siginiini y’omutwala edda ku siginiini ya baseband n’eyisibwa okuyita mu bitundu nga amplifier y’amaloboozi amatono, okukyusa wansi, n’okukyusa.

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

Okuyita mu nkola eyo waggulu, enkola ya RFID etuuse ku kumanyisa amawulire amalungi n’okutambuza amawulire, egaba omusingi ogwesigika ogw’okukozesa ennyo tekinologiya ow’okutegeera okw’otoma ataliiko kukwatagana.
