Ma tag apakompyuta a RFID amapangidwa ndi ma tag, owerenga ma rfid ndi makina osungira ndi kukonza.Malingana ndi njira zosiyanasiyana zoperekera mphamvu, RFID ikhoza kugawidwa m'magulu atatu: RFID yogwira ntchito, RFID yogwira ntchito, ndi RFID yosagwira ntchito.Memory ndi chip chokhala ndi mlongoti.Zomwe zili mu chip zitha kugwiritsidwa ntchito kuzindikiritsa chandamale.Ntchito yayikulu ndikuzindikira katundu.

Kusiyana pakati pa ma tag a RFID omwe akugwira ntchito, osagwira ntchito komanso osagwira ntchito motere:

1. Malingaliro

Active rfid imayendetsedwa ndi batire yomangidwa, gulu la ma tag amagetsi omwe amafotokozedwa ndi mitundu yosiyanasiyana yamagetsi amagetsi, ndipo nthawi zambiri amathandizira kuzindikira kwakutali. ndi ma tag a RFID opanda pake.Nthawi zambiri, nthawi zambiri amalowa m'malo ogona ndipo sagwira ntchito, ndipo satumiza zizindikiro za RFID kudziko lakunja.Pokhapokha pamene ili mkati mwa mayendedwe a siginecha yamagetsi othamanga kwambiri, chizindikiro chogwira chidzatsegulidwa ndikugwira ntchitoPassive rfid, ndiko kuti, chizindikiro cha ma radio frequency tag chitengera chonyamulira chogwirira ntchito, chimakhala ndi mphamvu zotsutsana ndi kusokoneza, ogwiritsa ntchito amatha kusintha mawonekedwe awo. kuwerenga ndi kulemba deta muyezo, dzuwa ndi yabwino kwambiri pa nsanja ntchito yapadera, ndi mtunda wowerenga akhoza kufika mamita oposa 10.

2. Mfundo yogwirira ntchito

Chizindikiro chamagetsi chogwira ntchito chimatanthawuza kuti mphamvu ya ntchito ya tag imaperekedwa ndi batri.Batire, kukumbukira ndi mlongoti pamodzi zimapanga tagi yamagetsi yogwira.Mosiyana ndi ma activation a ma frequency radio frequency, RFID yogwira imakhala ndi chosungira chodziyimira mkati.Mphamvu zonse, ndipo tumizanibe zambiri pokhazikitsa bandi ya ma frequency batire isanasinthidwe.
Ma tag omwe amagwira ntchito amakhala ndi mtunda wokulirapo wogwirira ntchito, malo okulirapo, ndi mphamvu zamakompyuta zamphamvu chifukwa cha mphamvu zawo mosalekeza, ndipo amatha kutumiza mwachangu ma siginecha okhala ndi zidziwitso zamafupipafupi kwa owerenga.Kudalirika kogwira ntchito ndikokwera, ndipo mtunda wotumizira chizindikiro ndi wautali.Komabe, chifukwa cha mphamvu ya batri, moyo wa ma tag omwe amagwira ntchito ndi ochepa, nthawi zambiri amakhala zaka 3-10 zokha.Pogwiritsa ntchito mphamvu ya batri pa tag, mtunda wa kutumizira deta udzakhala wocheperako komanso wocheperako, zomwe zidzakhudza kugwira ntchito kwadongosolo la RFID.

Semi-active rfid, ma tag apakompyuta omwe amagwira ntchito mu 433M frequency band kapena 2.4G frequency band.Zimagwira ntchito bwino pambuyo poyatsidwa.Kutalika kwa mtunda wa activator yapamwamba-frequency ndi yochepa, ndipo sikungathe kuyendetsedwa molondola pamtunda wawung'ono komanso pang'ono.Mwanjira imeneyi, chizindikiro chogwira ntchito chimayikidwa ndi activator yotsika kwambiri ngati malo oyambira, ndipo mfundo zoyambira zosiyana zimayikidwa m'malo osiyanasiyana, ndiyeno lalikulu Malowa amagwiritsa ntchito owerenga mtunda wautali kuti azindikire ndikuwerenga chizindikirocho, ndi kenako imakweza chizindikiro ku malo oyang'anira ndi njira zosiyanasiyana zokwezera.Mwanjira imeneyi, ntchito yonse yosonkhanitsa ma sign, kutumiza, kukonza, ndi kugwiritsa ntchito imamalizidwa.
Mofanana ndi chizindikiro chogwira ntchito, chizindikiro cha semi-active chilinso ndi batri mkati, koma batriyo imangopereka chithandizo cha dera lomwe limasunga deta ndi dera lomwe limasunga mphamvu yogwira ntchito ya chip, ndipo imagwiritsidwa ntchito kuyendetsa dera lophatikizidwa. mkati mwa tag kuti musunge magwiridwe antchito.
Chidziwitso chamagetsi chisanalowe m'malo ogwirira ntchito, chakhala chitakhala chosalala, chomwe chili chofanana ndi chizindikiro chokhazikika.Kugwiritsa ntchito mphamvu kwa batire mkati mwa tag ndikochepa kwambiri, kotero batire imatha kukhala zaka zingapo kapena zaka 10.Chizindikiro chamagetsi chikalowa m'malo ogwirira ntchito a owerenga, chimalimbikitsidwa ndi ma frequency a wailesi omwe amatumizidwa ndi owerenga, ndipo chizindikirocho chimalowa m'malo ogwirira ntchito.Mphamvu ya tag yamagetsi makamaka imachokera ku mphamvu yamagetsi yawayilesi ya owerenga, ndipo batire yamkati ya tag imagwiritsidwa ntchito makamaka popanga gawo la ma frequency radio.Mphamvu zosakwanira.

Kugwira ntchito kwa ma tag a rfid kumakhudzidwa kwambiri ndi kukula kwa tag, njira yosinthira, mtengo wagawo Q, magwiridwe antchito a chipangizocho komanso kuya kwa kusinthasintha.Ma Passive tag alibe magetsi omangidwa, ndipo amayendetsedwa makamaka ndi matabwa otumizidwa ndi owerenga RFID.
Pamene chizindikiro cha mawayilesi a gawo la electromagnetic momwe chizindikirocho chilili champhamvu mokwanira, zidziwitso zomwe zasungidwa mu chip zimatha kutumizidwa kwa owerenga, nthawi zambiri kuphatikiza chidziwitso cha ma tag, chandamale kapena chidziwitso choyenera cha eni ake. .
Ngakhale kuti mtunda wa ma tag amagetsi osagwira ntchito ndi waufupi, mtengo wake ndi wochepa, kukula kwake ndi kochepa, moyo wautumiki ndi wautali kwambiri, ndipo ukhoza kugwira ntchito m'madera osiyanasiyana ovuta, ndipo ukhoza kukwaniritsa zofunikira za machitidwe ambiri ogwiritsira ntchito pansi pa zosiyana. malamulo a wailesi.Amagwiritsidwa ntchito kwambiri pamsika.

Kodi kusankha RFID tag?
Ma tag apakompyuta omwe amagwira ntchito amakhala ndi mtunda wautali wogwiritsa ntchito, ndipo mtunda wapakati pa ma tag a RFID ndi owerenga RFID amatha kufika mamita makumi, kapena mazana a mamita, koma amakhudzidwa ndi kuchuluka kwa batri, nthawi ya moyo ndi yochepa, ndipo voliyumu yake ndi yayikulu komanso mtengo wake. apamwamba.
Ma tag apakompyuta a Passive ndi ang'onoang'ono, opepuka kulemera, otsika mtengo komanso wautali m'moyo.Zitha kupangidwa mosiyanasiyana monga mapepala kapena zomangira, ndipo zimagwiritsidwa ntchito m'malo osiyanasiyana.Popeza mulibe magetsi amkati, mtunda pakati pa ma tag a RFID ndi owerenga a RFID ndi ochepa, nthawi zambiri mkati mwa mita pang'ono kapena kuposa mamita khumi, zomwe zimafuna owerenga RFID amphamvu kwambiri.
Semi-active RFID: Mtengo wake ndi wocheperako, koma ntchitoyo ndi yaying'ono, ndipo zofunikira zogwiritsira ntchito ndizochepa.
