1. Tanthauzo
Active rfid, yomwe imadziwikanso kuti yogwira rfid, mphamvu yake yogwiritsira ntchito imaperekedwa kwathunthu ndi batire yamkati. Nthawi yomweyo, gawo la mphamvu ya batri limasinthidwa kukhala mphamvu yamagetsi yamagetsi yomwe imafunikira kulumikizana pakati pa tag yamagetsi ndi owerenga, ndipo nthawi zambiri imathandizira chizindikiritso chakutali.
Ma Passive tag, omwe amadziwika kuti passive tag, amatha kusintha gawo la mphamvu ya microwave kukhala yachindunji kuti agwire ntchito zawo atalandira chizindikiro cha microwave cholengezedwa ndi owerenga. Chidziwitso cha RFID chikayandikira owerenga RFID, mlongoti wa tag ya RFID imatembenuza mphamvu yolandila yamagetsi kukhala mphamvu yamagetsi, imayatsa chip mu tag ya RFID, ndikutumiza zomwe zili mu chipangizo cha RFID. Ndi luso loletsa kusokoneza, ogwiritsa ntchito amatha kusintha momwe amawerengera ndi kulemba; quasi-deta ndiyothandiza kwambiri pamakina apadera ogwiritsira ntchito, ndipo mtunda wowerengera ukhoza kufika mamita oposa 10.
2. Mfundo yogwira ntchito
1. Chizindikiro chamagetsi chogwira ntchito chimatanthawuza kuti mphamvu ya tag imaperekedwa ndi batri. Batire, kukumbukira ndi mlongoti pamodzi zimapanga tagi yamagetsi yogwira ntchito, yomwe ndi yosiyana ndi njira yotsegulira ma frequency radio frequency. Nthawi zonse imatumiza uthenga kuchokera mu bandi yafupipafupi batire isanasinthidwe.
2. Kuchita kwa ma tag a passive rfid kumakhudzidwa kwambiri ndi kukula kwa tag, mawonekedwe osinthika, mtengo wagawo Q, kugwiritsa ntchito mphamvu za chipangizo ndi kuya kwa kusinthasintha. Ma tag a ma frequency a Passive radio ali ndi 1024bits memory memory komanso Ultra-wide work frequency band, zomwe sizimangogwirizana ndi malamulo amakampani, komanso zimathandizira chitukuko chosinthika ndikugwiritsa ntchito, ndipo zimatha kuwerenga ndi kulemba ma tag angapo nthawi imodzi. Kapangidwe ka ma radio frequency tag, opanda batire, kukumbukira kumatha kufufutidwa mobwerezabwereza ndikulembedwa nthawi zopitilira 100,000.
3. Mtengo ndi moyo wautumiki
1. Rfid yogwira: mtengo wapamwamba komanso moyo wa batri waufupi.
2. Passive rfid: mtengo ndi wotsika mtengo kuposa rfid yogwira, ndipo moyo wa batri ndi wautali. Chachinayi, ubwino ndi kuipa kwa ziwirizi
1. Ma tag a RFID yogwira
Ma tag a Active RFID amayendetsedwa ndi batire yomangidwa mkati, ndipo ma tag osiyanasiyana amagwiritsa ntchito manambala osiyanasiyana ndi mawonekedwe a mabatire.
Ubwino: mtunda wautali wogwira ntchito, mtunda wapakati pa tag ya RFID yogwira ndi wowerenga RFID ukhoza kufika mamita makumi, ngakhale mazana a mamita. Zoipa: kukula kwakukulu, mtengo wapamwamba, nthawi yogwiritsira ntchito imakhala yochepa ndi moyo wa batri.
2. Passive RFID Tags
Chizindikiro cha RFID sichikhala ndi batri, ndipo mphamvu yake imachokera kwa owerenga RFID. Pamene RFID tag ili pafupi ndi owerenga RFID, mlongoti wa RFID tag amasintha mphamvu yamagetsi yolandirira kukhala mphamvu yamagetsi, imayendetsa chip mu tag ya RFID, ndikutumiza zomwe zili mu chipangizo cha RFID.
Ubwino: kukula kochepa, kulemera kochepa, mtengo wotsika, moyo wautali, ukhoza kupangidwa kukhala mawonekedwe osiyanasiyana monga mapepala owonda kapena zomangira zomangira, ndikugwiritsidwa ntchito m'madera osiyanasiyana.
Zoipa: Popeza mulibe magetsi amkati, mtunda wapakati pa RFID tag ndi wowerenga RFID ndi wochepa, nthawi zambiri mkati mwa mamita ochepa, ndipo wowerenga RFID wamphamvu kwambiri amafunikira.
