Yazisa indima yokumunca izinto ezisetshenziswayo kumathegi e-anti metal RFID

Ithegi ye-RFID yensimbi elwa nensimbi, ebizwa nangokuthi i-uhf RFID Ithegi Elimelene Nensimbi, amathegi kagesi enziwe ngezinto ezimuncayo ezinemisebenzi yokulwa nokuphazamiseka. Axazulula ngempumelelo inkinga yabathwali bensimbi abaphazamisa izimpawu zemvamisa yomsakazo wamathegi kagesi anamathele ezindaweni zawo.

Kumathegi e-RFID ensimbi ngezinto ezimuncayo zinezici ezilandelayo:

1. Abasebenzisi bensimbi Ithegi ye-Rfidbangenza ngokwezifiso ukufundwa kwedatha yabo ejwayelekile ukuze bathuthukise ukusebenza kahle kohlelo lokusebenza;

2. Amathegi e-RFID afakwe ngensimbi anebanga elide lokufunda (ibanga lokufunda nokubhala lihlobene nesifundi se-RFID kanye ne-antenna);

3. Ikhono elinamandla kakhulu lokulwa nokuphazamiseka;

4. Isikhathi eside sokugcina idatha, kuze kube yiminyaka engama-20, ukusebenza okubiza kakhulu;

5. Ukufundwa kwamathegi amaningi akuthinteki noma akunqunyelwe inani lamathegi endaweni yokusebenza;

6. Amathegi e-RFID ezindawo zensimbi asebenzisa umklamo webhendi yokusebenza ebanzi kakhulu, engagcini nje ngokuthobela imithethonqubo yemboni efanele, kodwa futhi engathuthukiswa futhi isetshenziswe ngendlela eguquguqukayo;

7. Indawo yokugcina iwukuba abasebenzisi benze imisebenzi yokufunda, yokubhala, yokusula kanye nokubhala kabusha ngokubethela, futhi ingacacisa nendawo yamagama ehlala njalo enikezelwe kubasebenzisi.
Ngokuthuthuka kwe-Intanethi Yezinto, ukusetshenziswa kwezinto ezimunca kumathegi e-RFID sekuvamile kakhulu manje. Ithegi yensimbi ye-UHF isetshenziswa nasezindaweni ezahlukene, okuhlanganisa ukuphathwa kwempahla, ukuphathwa kwezindawo zokugcina impahla, ukuphathwa kwempahla nakwezinye izindawo. Ngakho-ke iyini indima yokumunca izinto kuthegi yensimbi ye-uhf?

Kububanzi bemvamisa ye-RFID, lapho amaza kagesi ehlangana nezindawo zensimbi, ngenxa yento yamanje ye-eddy, kukhiqizwa ukubonakaliswa kwamaza kagesi aqinile, futhi kukhona umehluko wesigaba phakathi kwamaza kagesi abonakalayo namaza esigameko, okuholela ekukhanselweni okuhlangene. Ngalesi sikhathi, insimu ye-electromagnetic esebenza kahle ngempela iyancipha ngokushesha, ngoba lapho ukumelana kwezinto zensimbi kuphansi, kulapho ukulahlekelwa kwamanje kwe-eddy kuzoba kukhulu, futhi inkinga yensimbi iba nkulu kakhulu. Ngakho-ke, lapho i-antenna ibhekene nokuphazamiseka okukhulu kwensimbi, imiyalelo ekhishwe ngumfundi wekhadi izonyamalala ngokuphelele, ngakho-ke umphumela wokufunda idatha uyahluleka. Izinto ezimuncayo zisebenzisa kakhulu i-magnetic permeability property ephezulu. Uma isetshenziswa, ishidi lokumunca lifakwa phakathi kwe-antenna eyindilinga ye ithegi yensimbi ye-uhf RFID kanye ne-substrate yensimbi, okwandisa amathuba ensimu yamagnetic ebangelwayo ukuthi idlule ezintweni ezimuncayo uqobo futhi kunciphisa amathuba okudlula epuletini lensimbi, ngaleyo ndlela kunciphisa ugesi we-eddy obangelwayo okhiqizwa epuletini lensimbi. Izinto ezimuncayo zinciphisa kakhulu ukulahleka kwensimu yamagnetic ebangelwayo. Ngesikhathi esifanayo, ngenxa yokufakwa kweshidi lokuhlukaniswa kwamagnetic lezinto ezimuncayo, amandla e-parasitic alinganisiwe nawo azoncishiswa, futhi i-frequency offset izoncishiswa, okuhambisana nemvamisa ye-resonant yomfundi wekhadi, ngaleyo ndlela kuthuthukiswe kakhulu umphumela wokufunda ikhadi kanye nebanga.

Ukusetshenziswa okuyinhloko kwezimpawu zokungena kwamandla kagesi okuphezulu kwezinto ezimuncayo ukufaka ishidi lokumunca phakathi ithegi yensimbi ye-uhf RFIDI-antenna ebunjwe kanye ne-substrate yensimbi, kwandisa amathuba ensimu kazibuthe ebangelwayo idlula ezintweni ezimuncayo uqobo futhi kunciphisa amathuba okudlula epuletini lensimbi, ngaleyo ndlela kunciphisa ugesi we-eddy obangelwayo okhiqizwa epuletini lensimbi, futhi izinto ezimuncayo zinciphisa kakhulu ukulahleka kwensimu kazibuthe ebangelwayo. Ngesikhathi esifanayo, ngenxa yokufakwa kweshidi lokuhlukaniswa kukagesi wezinto ezimuncayo, umthamo we-parasitic olinganisiwe nawo uzoncishiswa, i-frequency offset izoncishiswa, futhi izohambisana nemvamisa ye-resonance yomfundi wekhadi, ngaleyo ndlela ithuthukise kakhulu umphumela wokufunda ikhadi kanye nebanga.

Amanye amaphrojekthi empilweni azohlangana nezimo ezahlukahlukene, njengokushisa okuphezulu nokuphansi, uketshezi, izindonga zesimende, amandla kazibuthe aqinile, insimbi, njll.

Isibonelo, endaweni yensimbi, ohlelweni lwe-ultra-high frequency identification tag (UHF) radio frequency identification tag, kunzima kakhulu ukuhlonza amathegi axhunywe kubathwali bensimbi ngoba izithiyo zensimbi zizobonakalisa futhi ziphazamise amagagasi kagesi. Njengamanje, kunezindlela ezine zokuxazulula ngempumelelo inkinga yokubamba ulwazi ezindaweni zensimbi:

1. Sebenzisa izinto ezimunca ukuze umunce amaza kagesi amaningi;

2. Ukwakheka kokuphakama kwephedi;

3. Ububanzi be-antenna yethegi kumele bube banele;

4. Umklamo we-antenna osekelwe phansi.

Njengamanje, indlela yethu evamile ukusebenzisa izinto ezimunca kanye nokuphakama kwephedi ngokuhlanganiswa. Indlela ekahle ukuklama i-antenna enomkhawulokudonsa omkhulu bese usebenzisa izinto ezimunca ukuphakama kwephedi, okuzofeza umphumela omuhle kakhulu.
