I-Anti-interference Effect ye-RFID Anti-metal Electronic Tag

I-RFID anti-metal electronic tag, eyaziwa nangokuthi umaka we-anti-metal we-high-frequency (ngokwezidingo zephrojekthi kanye nendawo yokufaka isicelo, futhi ingenziwa ngendlela oyifisayo umaka we-anti-metal ongu-125KHz/134.2KHz noma i-ultra-high-frequency 860~960MHz anti-metal tag, futhi kungenziwa ngokwezifiso umaka we-anti-metal osebenzayo ongu-2.45GHz), umaka we-elekthronikhi owenziwe ngezinto ezimuncayo ezinomsebenzi wokulwa nokuphazamiseka, okuyisombulula ngempumelelo inkinga yokuphazanyiswa kwesiginali ye-RF yesiphathi sensimbi kumaka we-elekthronikhi anamathiselwe endaweni yawo..
Isendlalelo sangaphandle se-RFID anti-metal electronic tag yakhiwe ngezinto ze-FR-4, okulingana nokwengeza into ekhethekile yokumunca insimbi ngesisekelo sethegi yasekuqaleni, ukuvimbela ukuphazamiseka kwezinto zensimbi kusiginali yethegi, ithegi futhi ine-anti-corrosion, ungangeni manzi, umsebenzi wokufakazela ama-asidi amathathu, ukumelana nokushisa okuphezulu, ukumelana nomthelela, anti-ukushayisana, ilungele ukusetshenziswa kwezindawo ezinokhahlo ezihlukahlukene.
I-RFID anti-metal electronic tag njengento emuncayo endimeni yokuphazamiseka kwesignali

Amathegi e-RFID anti-metal electronic anezinto ezimuncayo anezici ezilandelayo:

1. Omaka be-RFID anti-metal electronic bangakwazi ukufunda idatha yabo evamile ngokwenza ngokwezifiso ukuze kuthuthukiswe ukusebenza kahle kohlelo lohlelo lokusebenza;
2. Ibanga lokufunda ithegi ye-anti-metal electronic ye-RFID likude (ibanga layo lokufunda nokubhala lihlobene nomfundi we-RFID kanye ne-antenna);
3. Ikhono eliphezulu lokulwa nokuphazamiseka;
4. Isikhathi eside sokugcinwa kwedatha, kuya ku 20 iminyaka, kuqiza kahle;
5. Ukufundwa kwamathegi amaningi, ayithinteki futhi ikhawulelwe ngenani lamathegi endaweni yokusebenza;
6. I-RFID anti-metal tag yamukela idizayini ye-ultra-wide work frequency band, okungagcini nje ngokuhlangabezana nemithetho efanele yemboni, kodwa futhi ingathuthukiswa ngokuguquguqukayo futhi isetshenziswe;
7. Indawo yokugcina isetshenziswa abasebenzisi ukubethela ukufunda, bhala, sula futhi ubhale imisebenzi, futhi ingacacisa indawo yamagama azinikele unomphela yabasebenzisi.

Ngokuthuthukiswa kwe-inthanethi Yezinto, ukusetshenziswa kwezinto ezimunca igagasi kumathegi e-RFID sekuvame kakhulu, kanye namathegi e-RFID anti-metal electronic nawo asetshenziswa ezindaweni ezihlukahlukene, kuhlanganise nokuphathwa kwempahla, ukuphathwa kwempahla, ukuphathwa kwempahla nezinye izindawo. Ngakho-ke yini indima yokumunca izinto kumathegi e-RFID anti-metal?

Kububanzi befrikhwensi ye-RFID, lapho igagasi kagesi lihlangana nendawo yensimbi, ngenxa yesimo samanje se-eddy, i-electromagnetic wave reflection eqinile iyakhiqizwa, futhi kukhona umehluko wesigaba phakathi kwegagasi kazibuthe elibonisiwe kanye negagasi lesigameko, okuholela ekwesulweni okufanayo, ngalesi sikhathi insimu ye-electromagnetic esebenza ngempela iyancipha ngokushesha, ngoba i-resistivity ephansi yezinto zensimbi, kukhulu ukulahlekelwa kwamanje kwe-eddy kuzobangelwa, kubi kakhulu inkinga yensimbi. Ibhulogi, lapho ucingo lungaphansi kokuphazanyiswa okwedlulele kwensimbi, imiyalelo ekhishwe ngumfundi wekhadi izonyamalala ngokuphelele, ngakho umphumela wokufundwa kwedatha wehlulekile. Izinto ezimunca igagasi ikakhulukazi zisebenzisa izici zokungena okuphezulu. Lapho isetshenziswa, ipuleti elimunca igagasi lifakwa phakathi kwe-antenna eboshiwe ye-RFID anti-metal tag kanye ne-substrate yensimbi ukuze kwandiswe amathuba okuba kazibuthe edlula epuleti lensimbi ngento emunca igagasi ngokwayo., ngaleyo ndlela kunciphisa ukukhiqizwa kwe-eddy current efakwe epuleti lensimbi. Izinto ezimunca igagasi zibe sezinciphisa ukulahleka kwenkundla kazibuthe. Ngenxa yokufakwa kwesihlukanisi sezinto ezimuncayo, i-capacitance ye-parasitic elinganisiwe nayo izoncishiswa, futhi i-frequency offset izoncishiswa, okuhambisana nemvamisa ye-resonance yesifundi sekhadi, ngaleyo ndlela kuthuthukisa kakhulu umphumela wokufundwa kwekhadi kanye nebanga.

Amanye amaphrojekthi empilweni azohlangabezana nezindawo ezahlukahlukene, njengamazinga okushisa aphezulu naphansi, uketshezi, izindonga zikasimende, amandla kazibuthe, insimbi nokunye.
Ibhulogi, endaweni yensimbi, ku-ultra-high frequency (I-UHF) isistimu yokuhlonza ifrikhwensi yomsakazo, ukuhlonza ithegi enamathiselwe kusiphathi sensimbi kunzima kakhulu, ngoba izithiyo zensimbi zizobonisa futhi ziphazamise amagagasi kagesi. Okwamanje, ikakhulukazi kunezindlela ezine zokuxazulula ngempumelelo inkinga yokubamba ulwazi endaweni yensimbi:
1. Ukusetshenziswa kwezinto ezimunca ukumunca amagagasi kagesi ngokweqile;
2. Idizayini yobude obugoqiwe;
3. Umkhawulokudonsa we-antenna yethegi kufanele yanele;
4. Idizayini ye-antenna yohlobo lokuphansi.
Okwamanje, indlela yethu evamile ukwamukela inhlanganisela yezinto ezimuncayo kanye nokuphakama okugoqiwe, futhi indlela ekahle ukuklama uthi olunomkhawulokudonsa omkhulu, bese usebenzisa izinto ezimunca ukunamathisela ukuphakama, okuzofeza umphumela omuhle kakhulu.
