Udindo wofunikira wa antenna ya RFID mu dongosolo la RFID

Rfid Antena ndi mtundu wa chosinthira, chomwe chimasintha mafunde otsogozedwa omwe amafalikira pa chingwe chotumizira kukhala mafunde amagetsi omwe amafalikira mu sing'anga yopanda malire (nthawi zambiri malo omasuka), kapena kuchita kusintha kosiyana. Monga membala wapadera wa banja la ma antenna, ma antenna a RFID amachita gawo lofunikira mu dongosolo la RFID:

Mfundo yogwirira ntchito ya antenna ya RFID imachokera pa ukadaulo wolumikizirana pa wailesi, womwe antenna imalandira ndi kutulutsa ma signal a mafunde amagetsi kuti izindikire kuwerenga ndi kulemba kwa chidziwitso chosungidwa mu tag. Makamaka, antenna ya RFID ndi chipangizo chomwe chimatumiza ndikulandira ma signal a RF carrier. Ngati ma frequency ndi bandwidth yogwirira ntchito zatsimikiziridwa, antenna imatumiza RF carrier yopangidwa ndi RF processing module ndikulandira RF carrier yotulutsidwa kapena yowonetsedwa kuchokera ku tag.

Zizindikiro zonyamulira za RF izi ndiye maziko a dongosolo la RFID kuti lizindikire opanda zingwe komanso kusinthana deta.

Ntchito zazikulu za RFID antenna makamaka ndi izi:

Kutumiza zizindikiro: Antena ya RFID imayang'anira zizindikiro za RF zopangidwa ndi owerenga mu mawonekedwe a mafunde amagetsi omwe amatulutsa. Zizindikirozi zimakhala ndi malangizo ndi mphamvu zinazake, zomwe zimagwiritsidwa ntchito kuyatsa ndikulankhulana ndi Chikwangwani cha Rfids. Dongosolo la RFID la ma frequency osiyanasiyana, antenna imatumiza mafunde a chizindikiro ndi osiyana. Kapangidwe ndi magwiridwe antchito a antenna zimakhudza mwachindunji mphamvu ndi momwe zizindikiro zotumizira zimayendera. Antena yopangidwa bwino imatha kuyang'ana chizindikirocho mbali inayake, ndikuwonjezera kufalikira kwa chizindikirocho komanso kugwira ntchito bwino kwa kutumiza.

Landirani zizindikiro: pamene chizindikiro cha RFID chilandira chizindikiro chotumizidwa ndi wowerenga, chidzayankha chizindikirocho kudzera mu antenna yakeyake kubwerera kwa wowerenga. Antena ya RFID ndiyo imayang'anira kulandira zizindikiro izi kuchokera ku chizindikirocho, ndipo idzatumizidwa kwa wowerenga kuti ikonzedwe. Antena yolandira kukhudzidwa ndi kuthekera koletsa kusokonezedwa kuti ilandire molondola chizindikirocho ndi yofunika kwambiri. Antena yodziwika bwino imatha kulandira zizindikiro zofooka za chizindikirocho, ndipo kuthekera koletsa kusokonezedwa bwino kumatha kuchepetsa kusokonezedwa kuchokera ku chilengedwe chozungulira, ndikukweza khalidwe la chizindikirocho.

Momwe mungasankhire antenna yoyenera ya RFID

Kusankha antenna yoyenera ya RFID ndi gawo lofunika kwambiri pakuonetsetsa kuti makina a RFID akugwira ntchito bwino. Izi ndi zomwe mungasankhe. Ma Antena a Rfid Ndikofunikira kuganizira zina mwa zinthu izi:

1. kusankha pafupipafupi

Makina a RFID nthawi zambiri amagwira ntchito m'magawo atatu a ma frequency: ma frequency otsika (LF), ma frequency apamwamba (HF) ndi ma frequency apamwamba kwambiri (UHF). Mukasankha antenna, choyamba muyenera kudziwa kuti ndi ma frequency band ati omwe makina anu a RFID adzagwiritsa ntchito.

2. Chitsanzo Chogwiritsira Ntchito

Sankhani antenna kutengera momwe ntchito ikuyendera. Mwachitsanzo, ngati ikugwiritsidwa ntchito m'nyumba yosungiramo zinthu, antenna yowerengera kutali ingafunike; pomwe pakutsata zinthu zazing'ono, antenna yowerengera kutali ingakhale yoyenera kwambiri.

3. Kuwonjezeka kwa ma antenna

Kuchuluka kwa antenna kumakhudza mphamvu ya chizindikiro ndi mtunda wowerengera. Antena yochuluka imatha kuwerenga ma tag patali, koma mapu owongolera ma radiation akhoza kukhala ocheperapo; antenna yocheperako ndiyoyenera kuwerenga pafupi.

4. Mtundu wa antenna

Antena yozungulira: yoyenera kuwerenga ma tag pazinthu zathyathyathya.

Antena yozungulira ya polarization: yogwira ntchito ku malangizo a chizindikiro si yotsimikizika, ingathandize kupititsa patsogolo kuwerenga.

Antena yolumikizira mzere: yoyenera kutsogolera chizindikiro chodziwika bwino.

5. Njira yokhazikitsira

-Ganizirani njira yokhazikitsira antenna (monga yosasinthika, yoyenda, yolumikizidwa, ndi zina zotero), kuti muwonetsetse kuti antennayo ingagwire ntchito bwino pakugwiritsa ntchito kwenikweni.

6. Zinthu zachilengedwe

Ganizirani za malo omwe antenna idzagwiritsidwe ntchito (monga kutentha, chinyezi, mankhwala, ndi zina zotero), ndipo sankhani zipangizo ndi mapangidwe oyenera kuti muwonetsetse kuti antennayo ndi yolimba.

7. Mtundu wa Tag

Mitundu yosiyanasiyana ya ma tag (monga ma passive tag, ma active tag) ingakhale ndi zofunikira zosiyana pa antenna. Onetsetsani kuti antenna ikugwirizana ndi tag yomwe ikugwiritsidwa ntchito.

8. Kuwerengera kwa Mawerengedwe

Sankhani antenna malinga ndi mtunda wofunikira wowerengera, gwiritsani ntchito antenna yokwera kwambiri powerengera mtunda wautali ndi antenna yotsika kwambiri powerengera mtunda waufupi.

9. Mtengo

Sankhani antenna yomwe ikugwirizana ndi bajeti yanu. Ma antenna ogwira ntchito bwino nthawi zambiri amakhala okwera mtengo, koma akhoza kukhala ndalama zofunika pa ntchito zina.

Ndi chitukuko chachangu komanso kufalikira kwa ukadaulo wa intaneti ya zinthu, RFID antenna ngati gawo lofunikira la intaneti ya zinthu, mu code yoyamba dongosolo loyang'anira katundu lilinso ndi malo osasinthika, pakadali pano pali miyezo ndi ma protocol osiyanasiyana a ukadaulo wa RFID, omwe mpaka pamlingo wina amaletsa kukula kwa ntchito yake. M'tsogolomu, ndi kukhwima kosalekeza kwa ukadaulo ndi kufunika kwa msika, RFID antenna ikuyembekezeka kukwaniritsa miyezo ndi kukulitsa kuyanjana, kuchepetsa malire a ntchito, kulimbikitsa kufalikira ndi kugwiritsa ntchito ukadaulo wa RFID!
