Kodi mungachepetse bwanji vuto la kuwerenga molakwika kwa RFID tag?

Mu ndondomeko yeniyeni yofunsira, kuchuluka kwa kuwerenga kwaZolemba za UHFndi chinthu chofunikira kwambiri. Chifukwa kuwerenga kwa magulu, kuwonjezera pa liwiro la kuwerenga, ngati kungatsimikizire kuti kuwerenga bwino sikuphonya kuwerenga ndi chinsinsi chofunikira pakuwongolera bwino.

Mawu Ofunika: rfid label；wowerenga rfid；mlongoti wa rfid

Ndi kugwiritsa ntchito kwambiri kwa ma RFID applications, yalowa m'mbali zonse za miyoyo yathu. Ubwino wa ukadaulo wa RFID ndikuti ukhoza kusonkhanitsa deta yambiri mwachangu popanda kukhudzana mwachindunji ndi chinthu chozindikira. Komabe, ngakhale ukadaulo wabwino kwambiri ukhoza kukumana ndi "mavuto aukadaulo". Munjira yeniyeni yogwiritsira ntchito, kuchuluka kwa ma UHF labels ndikofunikira kwambiri. Chifukwa kuwerenga kwa batch, kuwonjezera pa liwiro la kuwerenga, kaya kungatsimikizire kuti kuwerenga bwino sikuphonya kuwerenga ndi chinsinsi chofunikira pakuwongolera bwino. Pali zinthu zambiri zomwe zimakhudza kuchuluka kwa kuwerenga. Ngakhale mu labotale titha kuyeza bwino mtunda wowerengedwa ndi nthawi yowerengedwa ya 100% ya kuchuluka kwa kuwerenga. Bola makina a khadi atsimikizika, malo a makina a khadi atsimikizika, ndipo chizindikiro, mtunda, ndi malangizo a antenna atsimikizika. Kuchuluka kwa kuwerenga kumatha kutsimikizika. Koma pakugwiritsa ntchito kwenikweni, vutoli ndi lovuta kwambiri.

Chifukwa chake, mu njira yeniyeni ya RFID antenna, kukhazikitsa ndi kukonza zolakwika za owerenga a RFID. Malo a ma antenna onse, Ngodya yoyika zinthu, ndi malo a owerenga a RFID ziyenera kusinthidwa mobwerezabwereza ndikutsimikiziridwa. Kuti mupeze mtunda wabwino kwambiri woyezera, kuchuluka kwa kuwerenga kwa owerenga makadi kuyeneranso kusinthidwa malinga ndi zosowa zenizeni. Kuchuluka kwa kuwerenga sikuli kwakukulu, kumakhala bwino, kuyenera kusungidwa mkati mwa malire enaake. Palinso malo ndi komwe chinthucho chikupita pamene kugula kupangidwa, komwe kulinso kwapadera. Zachidziwikire, pambuyo poti antenna ya omnidirectional igwiritsidwe ntchito, vuto la malo a antenna lidzachepa, koma limakhalabe ndi zotsatirapo.

Kuti muchepetse vuto la kusowa kwa kuwerenga kwa RFID Label, mutha kuyamba ndi izi:

1. Gwiritsani ntchito njira zowonjezera kuwerenga

M'malo omwe akukhudzidwa kwambiri ndi zitsulo ndi zakumwa, ukadaulo wowonjezera kuwerenga monga ma antenna owongolera ndi owerenga owonjezera ungagwiritsidwe ntchito kupititsa patsogolo luso la makinawo lolowera ndikukhazikitsa ma label. Maukadaulo awa amatha kupititsa patsogolo mtunda wotumizira ndi kulowa kwa ma RFID, potero amachepetsa nkhani ya kulephera kuwerenga ma tag.

2. Kusankha ndi kusintha zilembo

Kusankha chizindikiro cha RFID choyenera malo enaake ndi njira yofunika kwambiri yochepetsera vuto la kulephera kuwerenga. Posankha chizindikiro, zinthu monga kuyamwa kwa zinthuzo, kukula ndi mawonekedwe a chizindikirocho ziyenera kuganiziridwa. Pa malo omwe ali ndi zosowa zapadera, monga malo okhala ndi chitsulo kapena madzi ambiri, zilembo zopangidwa mwapadera zitha kusankhidwa kuti ziwongolere kuwerenga.

3. Konzani bwino kapangidwe ka zilembo

Kukonza bwino RFID Label ndiye chinsinsi chochepetsera vuto la kulephera kuwerenga. Kupewa mtunda wapafupi kwambiri ndi kusakanikirana pakati pa malembo kungachepetse kuchitika kwa kugundana. Kuphatikiza apo, malo ndi momwe lembalo limayendera zingakhudzenso momwe kuwerenga kumayendera. Chifukwa chake, pokonza RFID Label, ziyenera kuwonetsetsa kuti lembalo lili pamalo abwino kwambiri owerengera komanso momwe limayendera kuti muwongolere kuchuluka kwa kuwerenga.

4. Kapangidwe ndi kukhazikitsidwa kwa ma antenna

Kapangidwe ndi kuyika ma antenna kumakhudza kwambiri momwe ma RFID amagwirira ntchito. Kugwiritsa ntchito ma antenna opangidwa bwino komanso njira zabwino zoyika ma antenna kungachepetse zotsatira za njira zambiri komanso zopinga monga chitsulo ndi madzi pa ma RFID signals. Mwa kusintha komwe akupita ndi ngodya ya antenna, kuwunikira ndi kuchepetsa chizindikiro kungachepe kwambiri, ndipo luso la wowerenga kuwerenga bwino chizindikirocho lingawongoleredwe.

5. Kuwongolera bwino kwa sipekitiramu

Makina a RFID amagwira ntchito mu ma waya opanda zingwe ndipo amatha kusokonezedwa ndi ma signal kuchokera ku zipangizo zina zamagetsi. Kudzera mu kukonzekera bwino ndi kuyang'anira ma frequency spectrum omwe amagwiritsidwa ntchito ndi makina a RFID, kusankha ma frequency band opanda anthu kapena kugwiritsa ntchito ukadaulo wodumphira ma spectrum kungachepetse mphamvu ya signal interference, motero kukweza kuchuluka kwa kupambana powerenga RFID Label.
