Chifukwa chiyani rfid wotchuka?

Kuzindikira kwa RFID Imachititsa kuyankhulana kwa deta yoyendera kudzera payilesi yopanda zingwe, yomwe imatha kudziwa kuti muwerengedwa / kulemba / kulemba makadi a ma radio yamagetsi kapena ma radiory, pomaliza kudziwitsa zidziwitso.

Mfundo Zakutali Zakutali
1) Kusintha kwa RFID yakutali
Asanaphunzire mfundo za bulfid yakutali, ndikofunikira kuphunzira kapangidwe ka rfid. Dongosolo la RFID limakhala ndi magawo atatu: ma tag amagetsi, owerenga ndi olemba, makompyuta, ndi mapulogalamu awo a mapulogalamu. Ma tagi amagetsi makamaka opangidwa ndi ma antennas ndi madera ozungulira, omwe ali ndi ntchito yomaliza kulumikizana ndi RF Antennas. Wowerenga makamaka amakhala ndi magawo anayi: Antenna, chowongolera, ndi zingwe zopitilira muyeso {4} Ntchito yake yayikulu ndikuwerenga kapena kulemba zambiri zamagetsi ma tag. Ntchito za makompyuta ndi mapulogalamu ogwiritsira ntchito zimalumikizidwa ndi makompyuta akunja chifukwa cholumikizirana ndi olemba, kapena kwa a Resers System kuti akwaniritse kusinthanitsa kwa deta.
2) Kugwira ntchito ya RFUD yakutali
Wowerenga ndi Tag yamagetsi amapanga woyankha, ndipo mfundo yake yogwira ntchito ndi motere. Wowerenga amatumiza ma radio frower mu pafupipafupi ku malonda, amayendetsa molingana ndi osinthika kuti atumize deta yamkati, kenako amalandira motsatizana ndikutanthauzira zomwezo momwe mungagwiritsire ntchito.

Makhalidwe a Njira zakutali za RFFID
Pakadali pano, makina othamanga akutali ali ndi magulu awiri ogwiritsira ntchito makina awiri: Uhf ndi 2.45 ghz. Makina a Pasra { Ubwino wake umaphatikizapo mfundo zotsatirazi:
Nthawi yeniyeni: Kuyankha kwenikweni kwa nthawi, kuwerenga kokha kwa ID, komwe kungapeze chidziwitsochi.
Anti akumva: Kuwonetsedwa kwa microwave sikungapangidwe, kusinthidwa, kapena kukopera.
Ma Intaneti: Kuwunikira Zowunikira kudzera pa makompyuta apakompyuta.
Kulondola: Kulondola kwa chidziwitso kwa kuwerenga kuli kokwera ngati 99.99%.
Mtengo wotsika: Zimangowononga yuan pang'ono pomwe ntchito.
Kudalirika: Amachita ndi nyengo zovuta zachilengedwe monga fumbi, chinyezi, etc.
Kutalika kwa moyo: Palibe batire lofunikira pakugwiritsa ntchito, khadi yongodutsa yokha, yokonza zonse zonse zofunika.

Dongosolo lakutali la RFID limatengera makina opanda ma ngwe, ndipo malo opanda zingwe ndi ovuta kwambiri. Chifukwa chake, pali zinthu zambiri zomwe zimakhudza mtunda wazowerenga ndikulemba dongosolo lakutali, makamaka kuphatikiza mfundo zotsatirazi:
Zinthu zazikulu zomwe zimakhudza kuwerenga ndi kulemba mtunda wa makhadi a RF ndi mphamvu yotulutsa RF yomwe imapangitsa kuti owerenga, mphamvu zomwe zimawonetsedwa, kugwiritsa ntchito mphamvu za rf, zomwe adalandira ndi mphamvu za owerenga.
2. Zinthu zomwe zimakhudza zisonyezo pamwambapa ndizothandiza ndikuwonetsetsa gawo la GF.
Nthawi zonse zikamawonjezeka pansi pa malingaliro omwewo, malo ogwiritsira ntchito makina ogwiritsira ntchito rfid amatsika.
