Noo sheeg doorka nuugista agabka ee sumadda RFID ee ka hortagga birta

Tag RFID biraha lidka ku ah, oo sidoo kale loo yaqaan uhf RFID Tag Birta Ka-hortagga ah, waa calaamado elektaroonik ah oo laga sameeyay walxo nuugaya oo leh hawlo ka hortagga faragelinta. Waxay si wax ku ool ah u xalliyaan dhibaatada sideyaasha birta ah ee faragelinaya calaamadaha raadiyaha ee calaamadaha elektarooniga ah ee ku xiran dusha sare.

Calaamadaha RFID ee birta ah iyadoo walxaha nuugaya ay leeyihiin sifooyinka soo socda:

1. Isticmaalayaasha birta ku shaqeeya Taag RFIDs waxay habayn karaan akhrinta xogtooda caadiga ah si ay u horumariyaan hufnaanta nidaamka codsiga;

2. Calaamadaha RFID ee birta lagu rakibay waxay leeyihiin masaafo akhris dheer (masaafada akhriska iyo qorista waxay la xiriirtaa akhristaha RFID iyo anteenada);

3. Awood aad u xoog badan oo ka hortagga faragelinta ah;

4. Waqti dheer oo kaydinta xogta ah, ilaa 20 sano, waxqabad kharash badan;

5. Akhrinta calaamadaha badan saameyn kuma yeelanayso ama kuma xaddidayso tirada calaamadaha ku jira goobta shaqada;

6. Calaamadaha RFID ee dusha sare ee birta waxay qaataan naqshad xarig shaqo oo aad u ballaaran, kaas oo aan kaliya u hoggaansamin xeerarka warshadaha ee khuseeya, laakiin sidoo kale si dabacsan loo horumarin karo oo loo dabaqi karo;

7. Meesha kaydinta waxaa loogu talagalay dadka isticmaala inay sameeyaan hawlgallo akhris, qoraal, tirtirid iyo dib-u-qoris ah oo sir ah, waxayna sidoo kale qeexi kartaa meel erey oo joogto ah oo loogu talagalay dadka isticmaala.
Iyadoo la horumarinayo Internetka Waxyaabaha, adeegsiga walxaha nuugaya ee calaamadaha RFID hadda aad ayuu u badan yahay. sumadda birta UHF waxaa sidoo kale loo isticmaalaa deegaanno kala duwan, oo ay ku jiraan maaraynta saadka, maaraynta bakhaarrada, maaraynta hantida iyo meelo kale. Haddaba waa maxay doorka nuugista walxaha ee calaamadda birta ee uhf?

Kala duwanaanshaha inta jeer ee RFID, marka hirarka elektromagnetic-ka ay la kulmaan dusha sare ee birta, sababtoo ah ifafaalaha hadda socda ee eddy, milicsiga hirarka elektromagnetic-ka ee xooggan ayaa la sameeyaa, waxaana jira farqi marxaladeed oo u dhexeeya hirarka elektromagnetic-ka ee la milicsado iyo hirarka dhacdada, taasoo keenta in la joojiyo wadajirka ah. Waqtigan, goobta elektromagnetic-ka ee dhabta ah ee waxtarka leh ayaa si degdeg ah hoos ugu dhacda, sababtoo ah iska caabinta yar ee walxaha birta ah, ayaa sii weynaan doonta khasaaraha hadda socda ee eddy, iyo dhibaatada birta ee ay keento oo sii daran. Sidaa darteed, marka anteenadu ay la kulanto faragelin bir ah oo aad u daran, tilmaamaha uu soo saaro akhristaha kaarka ayaa gebi ahaanba baaba'aya, sidaa darteed natiijada akhrinta xogta waa guuldarro. Walxaha nuugaya waxay inta badan isticmaalaan hantida sare ee magnetic permeability. Marka la isticmaalayo, xaashida nuugista waxaa la geliyaa inta u dhaxaysa anteenada wareegsan ee sumadda birta ee uhf RFID iyo substrate-ka birta, kaas oo kordhiya suurtagalnimada in goobta birlabta ee la kiciyey ay dhex marto walxaha nuugaya lafteeda isla markaana yareeya suurtagalnimada inay dhex marto saxanka birta, taasoo yaraynaysa qulqulka eddy ee ka dhasha saxanka birta. Walxaha nuugaya ayaa sii yareeya luminta goobta birlabta ee la kiciyey. Isla mar ahaantaana, iyada oo ay ugu wacan tahay gelinta xaashida go'doominta birlabta ee la nuugayo, awoodda dulinka ee la cabbiray ayaa sidoo kale la dhimi doonaa, waxaana la dhimi doonaa inta jeer ee la cabbiro, taas oo la jaanqaadaysa soo noqnoqoshada resonant ee akhristaha kaarka, taasoo si weyn u hagaajinaysa saameynta akhrinta kaarka iyo masaafada.

Isticmaalka ugu weyn ee sifooyinka sare ee magnetic permeability ee walxaha nuugaya waa in la geliyo xaashida nuugaysa inta u dhaxaysa sumadda birta ee uhf RFIDAnteenada qaabaysan iyo substrate-ka birta, waxay kordhinayaan fursadda goobta birlabta ee la kiciyey inay dhex marto walxaha nuugaya lafteeda oo ay yareeyaan suurtagalnimada inay dhex marto saxanka birta, taasoo yaraynaysa qulqulka eddy ee la kiciyey ee ka soo baxa saxanka birta, walxaha nuugayana waxay sii yareeyaan luminta goobta birlabta ee la kiciyey. Isla mar ahaantaana, sababtoo ah gelinta xaashida go'doominta magnetic-ka ee walxaha nuugaya, awoodda dulinka ee la cabbiray ayaa sidoo kale la dhimi doonaa, hoos u dhigista soo noqnoqoshada ayaa la dhimi doonaa, waxayna la jaanqaadi doontaa soo noqnoqoshada resonance-ka ee akhristaha kaarka, taasoo si weyn u hagaajinaysa saameynta akhrinta kaarka iyo masaafada.

Mashruucyada qaar ee nolosha waxay la kulmi doonaan deegaanno kala duwan, sida heerkulka sare iyo kan hoose, dareere, derbiyada sibidhka, birlab xooggan, bir, iwm.

Tusaale ahaan, jawi bir ah, nidaamka aqoonsiga hirarka raadiyaha ee aadka u sarreeya (UHF), si gaar ah ayay u adag tahay in la aqoonsado calaamadaha ku xiran sidayaasha birta sababtoo ah caqabadaha birta ayaa ka tarjumaya oo faragelin doona hirarka elektromagnetic-ka. Waqtigan xaadirka ah, waxaa inta badan jira afar siyaabood oo si wax ku ool ah loogu xallin karo dhibaatada qabashada macluumaadka dusha sare ee birta:

1. Isticmaal walxaha nuugaya si aad u nuugto hirarka elektaroonigga ah ee xad-dhaafka ah;

2. Naqshadeynta dhererka suufka;

3. Ballaca anteenada calaamadda waa inuu ku filan yahay;

4. Naqshad anteeno dhulka ku taal.

Waqtigan xaadirka ah, habka aan u isticmaalno walxaha nuugaya iyo dhererka suufka ayaa isku dhafan. Habka ugu habboon waa in la naqshadeeyo anteeno leh baaxad weyn ka dibna loo isticmaalo walxaha nuugaya dhererka suufka, taas oo gaari doonta saameynta ugu fiican.
