Kodi mukudziwa kuti owerenga rfid?

Chidziwitso cha RFID Brecquecy ndikugwiritsa ntchito wailesi kufatsa zizindikiro, zomwe zimatha kuzindikira kuti sizingazindikire kuzindikiritsa zidziwitso. Pofuna dongosolo la RFID kuti ligwire bwino ntchito, limafunikira magawo awiri: chizindikiro chamagetsi ndi owerenga. Chizindikiro cha magetsi ndi chonyamulira cha data cha chizindikiritso cha wailesi. Imapangidwa ndi tag antenna ndi tag - yachidule. Wowerenga rfid ndiye chipangizo chachikulu chowerengera zambiri.

Wowerenga RFID amalankhula zingwe zamagetsi ndi magetsi a RFID yamagetsi kudzera (owerenga) anterna, ndipo amatha kuwerenga kapena kulemba deta yodziwika. Wowerenga wamba amaphatikizapo gawo lalitali (lolowera 1})

Rfid owerenga

Danga (loyera la - Panjira yophatikiza, kugulitsa mphamvu ndi kusinthana kwa deta kumakwaniritsidwa malinga ndi ubale. Kuti mumve zambiri za machitidwe a RFID

Ntchito ya owerenga RFID yotumiza malangizo:

1. Pulogalamu ya pulogalamu ya pulogalamuyi imapereka lamulo loti muitane gawo la chizindikiritso la Tag limatulutsa malangizo kuti atumizidwe kupeza chizindikirocho, ndikutumiza malangizowo ku gawo la baseband.

3. Zambiri zimayendetsedwa mu sigiriki ya seri ya seri ndikutumizidwa ku RF kutsogolo {1}

5. Pambuyo posefa, chizindikirocho chimatumizidwa ku mphamvu yakuundakuza kuti itsirizidwe, kenako ndikutumizidwa kuntena kuti iperekedwe.

 

Ntchito yoyeserera ya RFID kuti mulandire chidziwitso cha deta ya tag yobwerera:

1. Chitoliro cha magetsi amalandira chizindikiro kuchokera kwa owerenga, chimayamba mphamvu kuti apereke ndi mphamvu, ndipo amaweruza ngati yankho likufunika. Yankho likufunika, chidziwitsocho chimadutsa pamiyeso yopanda bata. yotumizidwa ku RF kutsogolo- malekezero.

2. Pambuyo posefa, chizindikiro chonyamula chimabwezeretsedwanso ku chizindikiro cha basebal ndikuyika kudzera pa otsika {{4} hereser hereser, pansi -

3. Zambiri zimatumizidwa ku gawo la baseband mu PC kudzera mu mawonekedwe.
