Kodi mungawongolere bwanji kuchuluka kwa kuwerenga kwa UHF RFID multi-tag?

Pogwiritsira ntchito ma RFID tag, nthawi zambiri pamafunika kuwerenga ma tag ambiri nthawi imodzi, monga kuchuluka kwa katundu m'nyumba yosungiramo katundu, kuchuluka kwa mabuku omwe ali mu laibulale, komanso kuwerenga ma tag ambiri kapena mazana a katundu pa malamba otumizira katundu kapena ma pallet. Pankhani ya katundu wambiri wowerengedwa, mwayi wowerengedwa bwino umatchedwa kuti muyeso wowerengera.

Ma tag a RFID osasinthikaAmagawidwa m'ma tag afupipafupi (LF), ma tag afupipafupi (HF) ndi ma tag afupipafupi (UHF). Ma tag a LF amagwiritsidwa ntchito kwambiri m'makina osavuta owongolera mwayi, ndipo mtunda wawo wowerengera nthawi zambiri umakhala mkati mwa masentimita 20. Ma tag a HF, kuphatikiza mndandanda wa NFC, ali ndi encryption yabwino ndipo amatha kuwerengedwa pafupi. Kenako palinso Chizindikiro cha RFID UHF, yomwe ndi chizindikiro chowerengera mtunda wautali, ndipo mtunda wowerengera ukhoza kufika mamita 2-8, ndipo chizindikiro cha UHF chingakhale ndi ntchito yoletsa kugundana, ndipo liwiro lowerenga ndi lachangu. Zizindikiro za UHF RFID nthawi zambiri zimagwiritsidwa ntchito pamene mtunda wowerengera ukuyembekezeka kukhala wautali ndipo mafunde a wailesi owunikira ndi okulirapo. Chifukwa chake, pankhani ya mayendedwe ndi unyolo woperekera, ukadaulo wa UHF RFID umasankhidwa padziko lonse lapansi.

Powerenga ma tag angapo, wowerenga amafunsa kaye, ndipo ma tagwo amayankha mafunso a wowerenga motsatizana. Ngati pali ma tag angapo omwe akuyankha nthawi imodzi panthawi yowerenga, wowerenga amafunsanso, ndipo ma tag ofunsidwawo adzalembedwa kuti "agone", motero amalepheretsa kuwerengedwanso.

Kuti muwongolere kuchuluka kwa ma multi-tags owerengedwa, nthawi yowerengera ndi nthawi yowerengera ikhoza kukulitsidwa, ndipo kuchuluka kwa kusinthana kwa chidziwitso pakati pa ma tag ndi owerenga kungawonjezeke. Kuphatikiza apo, njira zolumikizirana mwachangu pakati pa owerenga ndi ma tag zingathandizenso kuchepetsa kuchuluka kwa kuwerenga.

Kuwonjezera pa mtunda wowerengera ndi njira yowunikira yomwe yatchulidwa pamwambapa, kuchuluka kwa kuwerenga kudzakhudzidwanso ndi zinthu zina zambiri. Mwachitsanzo, liwiro la kuyenda kwa katundu pakhomo ndi potulukira, liwiro la kulumikizana pakati pa chizindikiro ndi wowerenga, zinthu zomwe zapakidwa ndi phukusi lakunja, momwe katunduyo amaikidwira, kutentha ndi chinyezi cha chilengedwe, kutalika kwa denga, ndi momwe wowerenga ndi wowerenga amakhudzira, ndi zina zotero.

Kuchuluka kwa kuwerenga kumakhudzananso ndi moyo wa zilembo. Zachidziwikire, zilembo zatsopano nthawi zambiri zimakhala ndi magwiridwe antchito abwino, kuwerenga mwachangu, komanso kuchuluka kochepa kwa kuwerenga komwe sikunawerengedwe. Komabe, ngati zilembozo sizigwiritsidwa ntchito ndikusungidwa bwino, nthawi ya moyo wa zilembozo ingafupikitsidwe. Mwachitsanzo, zilembo zina sizimalimbana ndi kuwala. Ngati ziwonetsedwa padzuwa kwa nthawi yayitali, nthawi ya moyo wa zilembozo idzakhala yochepa, zomwe zimafuna kusinthidwa nthawi zonse. Zolemba za RFID.

Ngati chizindikirocho chikugwiritsidwa ntchito panja, tikukulimbikitsani kugwiritsa ntchito chizindikiro china cha mafakitale. Nthawi yotsala ya zizindikirozi idzakhala yayitali. Chisamaliro chapadera chiyenera kuperekedwa pakugwiritsa ntchito zizindikiro m'malo achitsulo, makamaka pamene zizindikirozo zidzagwiritsidwa ntchito pazitsulo, ma tag otsutsana ndi zitsuloKupanda kutero, chitsulo chimatseka ma signali ambiri a wailesi, ndipo nthawi zambiri mipata imachitika.
