Anti-kusokoneza Zotsatira za RFID Anti-metal Electronic Tag

Anti-kusokoneza Zotsatira za RFID Anti-metal Electronic Tag

RFID anti-metal electronic tag, imadziwikanso kuti tag yapamwamba kwambiri yotsutsa zitsulo (molingana ndi zofunikira za polojekiti komanso malo ogwiritsira ntchito, imathanso kusinthidwa kuti ikhale yotsika kwambiri 125KHz/134.2KHz anti-zitsulo tag kapena ultra-high-frequency 860 ~ 960MHz anti-zitsulo tag, ndipo imathanso kusinthidwa kukhala 2.45GHz yogwira anti-zitsulo tag), ndi tag yamagetsi yopangidwa ndi zinthu zoyamwa ndi anti-interference function, zomwe zimathetsa bwino vuto la kusokoneza kwa chizindikiro cha RF cha chonyamulira zitsulo pa tag yamagetsi yomwe imayikidwa pamwamba pake..
Chosanjikiza chakunja cha RFID anti-metal electronic tag chimapangidwa ndi zinthu za FR-4, zomwe zikufanana ndi kuwonjezera chinthu chapadera chotsutsana ndi chitsulo chotengera pamaziko a chizindikiro choyambirira, kuteteza kusokoneza zinthu zitsulo pa chizindikiro chizindikiro, tag ilinso ndi anti-corrosion, chosalowa madzi, asidi-umboni atatu umboni ntchito, kutentha kwambiri kukana, kukana mphamvu, anti-kugunda, oyenera kugwiritsa ntchito mitundu yosiyanasiyana yankhanza.
RFID anti-metal tag yamagetsi ngati zinthu zoyamwa zomwe zimasokoneza ma sign

Ma tag amagetsi a RFID odana ndi zitsulo okhala ndi zinthu zoyamwa ali ndi izi:

1. Ma tag amagetsi a RFID odana ndi zitsulo amatha kuwerengera deta yawo mwamakonda kuti apititse patsogolo magwiridwe antchito;
2. RFID anti-metal electronic tag kuwerenga mtunda uli kutali (mtunda wake wowerengera ndi kulemba umagwirizana ndi owerenga RFID ndi mlongoti);
3. Kuthekera kwakukulu kotsutsana ndi kusokoneza;
4. Nthawi yosunga deta yayitali, mpaka 20 zaka, zotsika mtengo;
5. Kuwerenga kwama tag ambiri, osakhudzidwa ndi kuchepetsedwa ndi kuchuluka kwa ma tag pamalo ogwirira ntchito;
6. RFID odana ndi zitsulo tag utenga kopitilira muyeso-wide ntchito pafupipafupi bandi kamangidwe, zomwe sizimangokwaniritsa zofunikira zamakampani, komanso imatha kupangidwa mosinthika ndikugwiritsidwa ntchito;
7. Malo osungira amagwiritsidwa ntchito ndi ogwiritsa ntchito kubisa kuwerenga, lembani, kufufuta ndi kulemba ntchito, komanso akhoza kutchula malo okhazikika odzipereka a mawu kwa ogwiritsa ntchito.

Ndi chitukuko cha intaneti ya Zinthu, kugwiritsa ntchito zida zoyamwa mafunde m'ma tag a RFID kwakhala kofala kwambiri, ndi ma tag amagetsi a RFID odana ndi zitsulo amagwiritsidwanso ntchito m'malo osiyanasiyana, kuphatikizapo kasamalidwe ka zinthu, kasamalidwe ka nkhokwe, kasamalidwe ka chuma ndi malo ena. Ndiye ntchito yotengera zida mu RFID anti-metal tag ndi chiyani?

Mu RFID frequency range, pamene mafunde a electromagnetic akumana ndi chitsulo pamwamba, chifukwa cha zochitika za eddy panopa, chowunikira cholimba cha electromagnetic wave chimapangidwa, ndipo pali kusiyana kwa gawo pakati pa chiwonetsero cha electromagnetic wave ndi ma wave wave, kupangitsa kuti onse asiyane, panthawiyi mphamvu yeniyeni yamagetsi yamagetsi imachepetsedwa mofulumira, chifukwa m'munsi resistivity wa zinthu zitsulo, m'pamenenso kutayika kwa eddy panopa kudzayambika, vuto lalikulu kwambiri lachitsulo. Choncho, pamene waya akukumana ndi kusokoneza kwambiri zitsulo, malangizo operekedwa ndi owerenga khadi adzasowa kotheratu, kotero zotsatira zowerengera zalephera. Zinthu zotengera mafundezi makamaka zimagwiritsa ntchito mawonekedwe apamwamba kwambiri. Pamene ntchito, mbale yotulutsa mafunde imayikidwa pakati pa mlongoti wamalata wa RFID anti-metal tag ndi gawo lapansi lachitsulo kuti achulukitse kuthekera kwa mphamvu ya maginito kudutsa mu mbale yachitsulo kupyola muzinthu zomwe zimayamwa ndi mafunde pawokha., potero kuchepetsa m'badwo wa induced eddy panopa mu mbale zitsulo. Zinthu zotengera mafundezi zimachepetsa kutayika kwa mphamvu ya maginito. Chifukwa cha kuyika kwa cholekanitsa chotengera zinthu, kuyesedwa kwa parasitic capacitance kudzachepetsedwanso, ndipo ma frequency offset adzachepetsedwa, zomwe zimagwirizana ndi kuchuluka kwa resonance kwa owerenga makhadi, motero kuwongolera kwambiri kuwerenga kwamakhadi ndi mtunda.

Ntchito zina m'moyo zimakumana ndi malo osiyanasiyana, monga kutentha kwambiri ndi kutsika, zamadzimadzi, makoma simenti, wamphamvu maginito, zitsulo ndi zina zotero.
Mwachitsanzo, m'malo achitsulo, pafupipafupi kwambiri (UHF) radio frequency identification tag system, chizindikiritso cha chizindikiro chophatikizidwa ndi chonyamulira zitsulo ndizovuta kwambiri, chifukwa zopinga zachitsulo zidzawonetsa ndikusokoneza mafunde a electromagnetic. Pakadali pano, pali makamaka njira zinayi zothetsera bwino vuto la kuzindikira zambiri pazitsulo:
1. Kugwiritsa ntchito zinthu zoyamwa kuti mutenge mafunde owonjezera a electromagnetic;
2. Padded kutalika kapangidwe;
3. Bandwidth ya tag antenna iyenera kukhala yokwanira;
4. Mapangidwe amtundu wa antenna.
Pakadali pano, njira yathu wamba ndi kutengera kuphatikiza zinthu kuyamwa ndi kutalika padded, ndipo njira yabwino ndiyo kupanga antenna yokhala ndi bandwidth yayikulu, ndiyeno ntchito kuyamwa zipangizo kuti padded kutalika, zomwe zidzakwaniritse zotsatira zabwino kwambiri.
