Anti{{0}Matag a Metal NFC: Momwe Amagwirira Ntchito & Momwe Mungasankhire

Anti-chitsulo NFC tag ndi NFC tag yomangidwa ndi ferrite kapena maginito shielding layer pakati pa tinyanga ndi chitsulo chomwe amakhalapo, motero imagwira ntchito pa zida, makina, makabati, zowongolera, ndi kupaka zitsulo. Chomata chokhazikika cha NFC chomwe chimayikidwa mwachindunji pachitsulo nthawi zambiri chimalephera: chitsulo chimachotsa mlongoti ndi kutengera mphamvu yomwe tagi imafunikira kuti iyambike. Ngati tagi yanu idzakwezedwa pamwamba kapena pafupi ndi chitsulo, mukufunika tagi ya-metal (ferrite-backed), ndipo muyiyese pamalo enieni ndi foni yeniyeni musanayitanitsa voliyumu.

Bukuli likufotokoza chifukwa chakema tag wamba a NFCkulimbana ndi zitsulo, momwe anti-ma tag azitsulo a NFC amathetsera vutoli, momwe mitundu yosiyanasiyana ndi tchipisi zimafananirana, ndi njira yothandiza yosankha, kuyesa, ndi kugula tagi yoyenera pulojekiti yanu.

Yankho Mwachangu

Gwiritsani ntchito zomata za NFC zokhazikika papulasitiki, galasi, matabwa, kapena makatoni. Gwiritsani ntchito anti-chitsulo cha NFC tag (yomwe imatchedwanso-chitsulo NFC tag kapena chitsulo-mount NFC label) nthawi iliyonse yomwe tagyo yakhazikika kuchitsulo kapena kukhala pansi mamilimita ochepa kuchokera pamenepo. Chosanjikiza cha ferrite chimateteza mlongoti kuchitsulo, kubwezeretsa kudalirika kwa kuwerenga pamtengo wa tag wokhuthala pang'ono, wokwera mtengo.

Chifukwa chiyani Ma Tag Okhazikika a NFC Sagwira Ntchito Bwino pa Zitsulo?

NFC ndiukadaulo wapafupi-umagwira ntchito pa 13.56 MHz. Owerenga (foni yanu) ndi tag amalumikizidwa kudera laling'ono la maginito, ndipo chizindikirocho chimakoka mphamvu zake zonse kuchokera pamenepo. Palibe batire mu tag ya NFC yongokhala. Mutha kuwerenga zambiri za zoyambira paNdemanga zaukadaulo za NFC Forum.

Mukayika chizindikiro chokhazikika pachitsulo, zinthu zitatu zimakutsutsani. Chitsulochi chimachita ngati chachifupi-chizungulire chozungulira ndipo chimatenga mphamvu kuchokera kumunda (mafunde a eddy), motero mphamvu yochepera imafika ku chip. Chitsulocho chimasinthanso kusintha kwa mlongoti kuchoka pa 13.56 MHz, vuto lomwe akatswiri amatcha kuti detuning. Pomaliza, chitsulocho chimasokoneza mawonekedwe a munda mozungulira chizindikirocho. Pamodzi zotsatirazi zikutanthauza kuti chizindikirocho sichingasonkhanitse mphamvu zokwanira kudzuka konse.

Mwakuchita, chomata cha NFC chokhazikika pazitsulo chimakonda kuwonetsa chimodzi kapena zingapo mwa izi:

• Sichiyang'ana konse, ngakhale foni ikakanizidwa molunjika.
• Mtunda wowerengeka umagwera pafupifupi chilichonse, kotero foni iyenera kukhudza malo ang'onoang'ono okoma.
• Imakhudzidwa kwambiri ndi ngodya, ndipo kupendekeka pang'ono kumasokoneza kuwerenga.
• Zinagwira ntchito bwino pa benchi yogwirira ntchito koma zinasiya kugwira ntchito zitagwiritsidwa ntchito ku zipangizo.

Mfundo yomalizayi ndi yomwe imawononga ndalama zambiri: chizindikiro chovomerezeka pa desiki lathyathyathya chimatha kulephera m'munda. Ichi ndichifukwa chake mawonekedwe omwe mumayesa pazinthu monga tag yomwe.

Kodi Anti{{0}Metal NFC Tags Amagwira Ntchito Motani?

Anti-chitsulo cha NFC tag chimawonjezera ferrite (chinthu chofewa mwa maginito) pakati pa tinyanga ndi chitsulo. Ferrite imapangitsa kuti mphamvu ya maginito ikhale yochepa-njira yotayika kuti idutse, motero gawolo limakhazikika mozungulira mlongoti m'malo momwedwa ndi chitsulo pansi. M'malo mwake, ferrite imapatula mlongoti pamwamba ndikukhazikitsanso-kukhazikika kwake, zomwe ndizomwe zimabwezeretsa kuwerenga.

Orientation ndiyofunikira. Munda wolondola, kuyambira pa foni mpaka pamwamba, ndi: foni kapena wowerenga → tag nkhope → mlongoti wa NFC ndi chip → wosanjikiza wa ferrite → pamwamba pazitsulo. Ferrite iyenera kukhala pakati pa mlongoti ndi chitsulo. Ngati chizindikiro chakwera mozondoka, kapena ngati ferrite ikusowa kumbali yachitsulo, chishango sichichita kalikonse.

Kodi mkati mwa -tagi yachitsulo ya NFC muli chiyani?

Zimathandizira kujambula zigawo, chifukwa chilichonse chimakhudza magwiridwe antchito, kulimba, komanso mtengo wake:

• Pamwamba ndi kusindikiza wosanjikiza- nkhope yowoneka, yomwe imatha kunyamula chizindikiro, malangizo, chizindikiro cha NFC, kapena nambala yosindikizidwa.
• Kuyika kwa antenna ndi chip- koyilo ndi NFC IC zomwe zimasunga ndikubweza deta yanu.
• Ferrite wosanjikiza- zotchinga zomwe zimapangitsa kuti-zigwire ntchito pazitsulo.
• Zomatira wosanjikiza- mgwirizano pamwamba; pazitsulo zopindika kapena zamafuta nthawi zambiri ndi gawo lomwe limalephera poyamba.
• Kutulutsa liner- kuthandizira kumachotsedwa pakukhazikitsa.

Anti{{0}Ma tagi a Metal NFC vs Standard NFC Tags

Lamulo losavuta: sankhani tagi yokhazikika pomwe pamwamba si-zachitsulo ndipo palibe chitsulo chotseka kumbuyo kwake. Sankhani anti-metal tag pamene pamwamba ndi chitsulo, pamene pali zojambulazo kapena zitsulo mamilimita angapo kuseri kwa chivundikiro chopyapyala chosakhala-chopanda chitsulo, kapena ngati simukutsimikiza ndipo simungathe kuyesa pasadakhale.

Anti{{0}Metal NFC vs UHF Anti-Metal RFID: Musawasokoneze

Anthu omwe amafufuza "anti-ma tag achitsulo" nthawi zambiri amaphatikiza matekinoloje awiri osiyana kwambiri. NFC ndi yokwera-kawirikawiri, pafupi-panjira yopangira kuti muzitha kuyimbira foni dala pafupi. UHF RFID (mozungulira 860–960 MHz) ndi njira yakutali-yoyenera kuwerenga ma tag ambiri patali ndi owerenga odzipereka, umo ndi momwe nyumba zosungiramo katundu ndi zowerengera katundu zimawerengera kuchuluka kwake.

Ngati cholinga chanu ndi "wantchito amadula foni pamakina ndikutsegula mbiri yake," mukufuna anti-chitsulo cha NFC tag. Ngati cholinga chanu ndi "kuyenda pansi ndikuwerenga zitsulo makumi asanu nthawi imodzi," imeneyo ndi ntchito yaUHF anti-ma tag achitsulo a RFID, osati NFC. Kusankha banja lolakwika ndi chimodzi mwa zolakwika zodula kwambiri-zolemba ma tagi, choncho yankhani funsoli kaye.
