Ziya Kufundeka Kude Kangakanani Iithegi zeRFID?

 

Iithegi ze-passive zisebenza kumgama omfutshane. Iithegi ezisebenzayo zisebenza kude kakhulu. Amanani ngqo axhomekeke kwisixhobo, rhoqo, kwaye yintoni phakathi kwethegi kunye nomfundi.

 

Impendulo ibalulekile ngoku kuba iQualcomm ithe kulo nyaka uphelileyo izakubeka abafundi be-UHF RFID kwiichips zefowuni. IZebra ithumele ngenqanawa ifowuni yeshishini enomfundi{1}owakhelwe ngaphakathi ngoJanuwari. I-RAIN Alliance ibhengeze iprojekthi eqhelekileyo ye-smartphone ngo-Matshi. Ukuba ezi nzame ziyaphumelela, iithegi ezifanayo ezisetyenziswa ngabathengisi ukulandelela uluhlu lwezinto ezinokufundwa nguye nabani na onefowuni.

 

 

Uninzi lweethegi ze-RFID kwiivenkile zi-UHF esebenzayo. Abanayo ibhetri. Xa umfundi ethumela amaza erediyo, ithegi ifunxa amandla awoneleyo ukunika amandla itshiphu yayo kwaye ibuyise umva umqondiso oqulethe inombolo yesazisi. Ithegi ngokwayo ayenzi phantse nto. Umfundi uyawenza umsebenzi.

 

Ngaphantsi kweemeko ezilungileyo i-tag ye-UHF ye-passive ingafundwa kwiimitha ezili-10. Iimeko ezilungileyo zithetha umoya ovulekileyo, akukho ntsimbi ekufutshane, akukho lulwelo, ithegi iqondiswe ngokuchanekileyo xa ithelekiswa ne-eriyali yokufunda. Ufakelo lweWarehouse eneencwadi zokufunda ezisisigxina kunye nee-eriyali eziphakamileyo-zokufumana i-12 okanye i-15 yeemitha. Iinkcukacha ezisuka kubavelisi beethegi zihlala zithatha iiseti ezifanelekileyo ezingekhoyo kwiindawo zokugcina iimpahla.

 

Beka itegi efanayo kwishelufu yesinyithi kwaye uluhlu luyehla. Yibeke kwibhotile yamanzi kwaye iyancipha ngakumbi. Isinyithi sibonakalisa umqondiso. Amanzi ayawafunxa. Ukuqhelaniswa nethegi ngokunxulumene ne-eriyali yokufunda ibalulekile. Umfundi onelayini{5}}enomgca owenziweyo ufuna ithegi ilungelelaniswe ngendlela ethile. Isetyhula-i-eriyali ezipolarized ziyaxolela kodwa zincama uluhlu oluthile.

 

 

{0}}ithegi zefrikhwensi ephantsi kwi-125 kHz efundwa kwi-10 yeesentimitha okanye ngaphantsi. Ezi zingena kumakhadi okufikelela kunye neetshiphusi zokulandelela izilwanyana. High-ithegi zefrikhwensi kwi-13.56 MHz zifikelela malunga nemitha. Amakhadi entlawulo asebenzisa le band. Uluhlu olufutshane luphawu. Ucofa ikhadi kwitheminali. Awuyitshangatshangisa ukusuka ngaphaya kwegumbi.

 

Iithegi ezisebenzayo zahlukile. Zineebhetri. Basasaza. Basebenza kwiimitha ezingama-30, iimitha ezingama-50, iimitha ezili-100 ngokuxhomekeke kulungiselelo. Ezinye iinkqubo zoshishino zifunde iithegi ezisebenzayo kumakhulu amaninzi eemitha. Ibhetri yongeza ixabiso kunye nobukhulu. Ekugqibeleni iyafa. Kodwa ukulandelela iikhonteyina zokuthumela ngenqanawa okanye izithuthi kwiyadi yonke, uluhlu lokwenziwayo alwanelanga.

 

Umbuzo wefowuni umalunga nokwenziwa kwe-UHF. Ifowuni ayikwazi ukulingana nee-eriyali ezinkulu ezisetyenziswa ngabafundi be-warehouse. Imigaqo iyanciphisa ukuba angakanani amandla osasazo oluphathwa ngesandla. UThomas Brunner e-Kathrein Solutions uqikelelo lwefowuni{{3}olusekwe kubafundi bangafikelela kwi-120 yeesentimitha ngokugqibeleleyo. Oko kukufutshane ekucofe ikhadi lokuhlawula kunokuskena uluhlu lwempahla kwivenkile yonke.

 

 

UKatherine Albrecht uchithe iminyaka elumkisa ngeRFID. Unesidanga sobugqirha eHarvard. Waseka iqela labathengi elibizwa ngokuba yiCASPIAN ngo-1999. Wabhala incwadi ngo-2005 ebiza iithegi zeRFID "ii-spychips." Le ncwadi icaphule i-IBM kunye ne-BellSouth yokufayila i-patent echaza iindlela zokulandelela abantu ngeethegi kwiimpahla zabo kunye nenkunkuma. Abantu boshishino bathi ubaxekile. Uthe baceba ukucupha abantu abaninzi. Ingxabano ayizange ide isonjululwe. Iithegi zangena kwiimveliso kunjalo.

 

Umbuzo wabucala uxhomekeke ngokuyinxenye kuluhlu. Ithegi efundeka ngeesentimitha ezimbini kunzima ukuyiskena ngokufihlakeleyo. Ithegi efundeka kwiimitha ezili-10 ilula. Ifowuni efunda kwimitha ikwindawo ethile phakathi. Nokuba loo nto ibalulekile ixhomekeke kulwazi oluqulathwe yithegi kwaye ifunwa ngubani.
