Khadi lachidziwitso la RFID (Radio Frequency Identification) lonyowa ndi kagawo kakang'ono, kosinthika kamene kamakhala ndi zozungulira za RFID , kuphatikizapo mlongoti ndi microchip. Zolowetsazi zimagwiritsidwa ntchito popanga RFID makadi, omwe amatha kusunga ndi kutumiza deta popanda zingwe akafufuzidwa ndi wowerenga RFID . Nthawi zambiri amapezeka m'makhadi owongolera, makhadi olipira opanda kulumikizana, ndi makadi osiyanasiyana anzeru.
Kuwerenga mtunda, komwe kumatchedwanso kuti kuwerenga, ndi gawo lofunikira muukadaulo wa RFID . Zimatanthawuza kutalika kwa mtunda womwe wowerenga RFID atha kulumikizana bwino ndi tag ya RFID . Mtunda wowerengedwa umatsimikizira kuti RFID khadi lingakhale kutali bwanji ndi wowerenga pamene akuwoneka ndikuwerengedwa molondola. Izi ndizofunikira pakuwonetsetsa kuti machitidwe a RFID akugwira ntchito mosiyanasiyana.
RFID ma tag amagwira ntchito mosiyanasiyana: pafupipafupi ( LF ), pafupipafupi ( HF ), ndi ultra-high frequency ( UHF ). Mafupipafupi amakhudza mtunda wowerengera kwambiri. LF ma tag nthawi zambiri amakhala ndi zowerengera zazifupi koma siziwopsezedwa ndi zitsulo ndi zamadzimadzi. HF ma tag amapereka mtunda wowerengeka bwino ndipo amagwiritsidwa ntchito kwambiri m'makhadi olipira opanda kulumikizana. UHF ma tag amapereka mitunda yayitali kwambiri yowerengera koma imatha kukhudzidwa kwambiri ndi chilengedwe.
Kukula ndi kapangidwe ka tinyanga mkati mwa RFID tag khadi yonyowa inlay imathandizira kwambiri kudziwa mtunda wowerengeka. Ma antennas akulu nthawi zambiri amapereka mawerengedwe ochulukirapo chifukwa cholandila bwino ma siginecha. Kuphatikiza apo, mawonekedwe ndi mawonekedwe a tinyanga tating'onoting'ono amatha kukhudza mphamvu ya maginito amagetsi, zomwe zimakhudza mtunda wowerengeka.
Zinthu zachilengedwe monga kupezeka kwa zitsulo, zamadzimadzi, ndi kusokoneza kwa ma electromagnetic zimatha kukhudza mtunda wowerengeka wa ma tag a RFID . Malo achitsulo amatha kuwonetsa ndi kuyamwa ma siginecha a RF, kuchepetsa kuwerengera koyenera. Momwemonso, zamadzimadzi zimatha kutulutsa mlongoti, ndikupangitsa kuchepa kwa magwiridwe antchito. Mikhalidwe ya chilengedwe iyenera kuganiziridwa popanga ndi kutumiza machitidwe a RFID kuti awonetsetse mtunda wowerengeka bwino.
Passive RFID ma tag alibe mphamvu yamkati. Amadalira mphamvu zoperekedwa ndi RFID owerenga kuti azipatsa mphamvu ma microchip ndi kufalitsa deta. Ma Passive tag ndi otsika mtengo komanso oyenera kugwiritsa ntchito zambiri, koma mawerengedwe awo amakhala aafupi poyerekeza ndi ma tag omwe akugwira ntchito.
Ma tag a Active RFID ali ndi mphamvu zawozawo, nthawi zambiri amakhala ndi batire, zomwe zimawalola kutumiza ma siginecha mtunda wautali. Ma tag awa ndi abwino kwa mapulogalamu omwe amafunikira mawerengedwe otalikirapo komanso ma data apamwamba kwambiri. Komabe, ndi okwera mtengo kwambiri ndipo amakhala ndi nthawi yochepa yogwira ntchito chifukwa cha zovuta za batri.
Semi-passive RFID ma tag, omwe amadziwikanso kuti ma tag a batri-assisted passive (BAP), amaphatikiza ma tag omwe amangokhala komanso osagwira ntchito. Iwo ali ndi batire laling'ono mphamvu microchip, utithandize kuwerenga mtunda ndi kudalirika akadali kudalira chizindikiro owerenga yambitsa kufala deta. Ma tag awa amapereka malire pakati pa magwiridwe antchito ndi mtengo.
Mtunda wowerengera umatanthauzidwa ngati kuchuluka kwakukulu komwe wowerenga RFID angazindikire ndikulumikizana ndi tagi ya RFID . Mtunda umenewu umayesedwa pansi pa mikhalidwe yeniyeni, makamaka m'malo olamulidwa, kuti mudziwe momwe ndondomeko ya RFID ikuyendera bwino. Muyesowo umaganizira zinthu monga ma tag, mphamvu ya owerenga, ndi momwe chilengedwe chikuyendera.
Zinthu zingapo zitha kuwonjezera kuchuluka kwa ma tag a RFID , kuphatikiza:
Kuchulukitsa mphamvu ya owerenga RFID .
Kuwongolera kapangidwe ka antenna ndi mawonekedwe ake.
Kugwiritsa ntchito ma tag apamwamba kwambiri (mwachitsanzo, UHF ) pamatali owerengera otalikirapo.
Kuchepetsa kusokoneza chilengedwe posankha zipangizo zoyenera ndi malo otumizira.
RFID ma tag makadi olowera monyowa amagwiritsidwa ntchito kwambiri m'makina owongolera mwayi wolowera nyumba, zipinda, ndi malo oletsedwa. Kutalikirana kwa makhadiwa kumathandizira ogwiritsa ntchito kulowa popanda kulumikizana mwachindunji ndi owerenga, kupangitsa kuti zikhale zosavuta komanso zotetezeka.
Mu kasamalidwe ka zinthu, RFID ma tag card wet inlays amathandizira kufufuza ndi kuyang'anira katundu m'malo osungiramo katundu ndi malo ogulitsa. Kutalikirana kowerengera kwa ma tag a RFID kumathandizira kusanthula bwino zinthu patali, kuwongolera kulondola kwazinthu ndikuchepetsa ntchito yamanja.
Makhadi anzeru okhala ndi RFID ma tag card monyowa amagwiritsidwa ntchito m'mapulogalamu osiyanasiyana, kuphatikiza zolipirira popanda kulumikizana, zoyendera za anthu onse, ndi zizindikiritso. Mtunda wowerengeka wa makhadiwa umatsimikizira kuchitapo kanthu mwachangu komanso mosasamala komanso njira zozindikiritsira.
Mtunda wowerenga umakhudza kwambiri magwiridwe antchito ndi kudalirika kwamakadi a RFID . Makhadi okhala ndi magawo osawerengeka osakwanira angafunike kuti ogwiritsa ntchito azikhala pafupi kwambiri ndi owerenga, zomwe zimabweretsa zovuta komanso kuchedwa kwa ntchito. Kuonetsetsa mtunda wowerengeka wokwanira kumakulitsa luso la wogwiritsa ntchito komanso kugwiritsa ntchito bwino dongosolo.
Mukamapanga makhadi a RFID , pali zinthu zingapo zomwe ziyenera kuganiziridwa kuti muzitha kuwerenga bwino. Izi zikuphatikiza kusankha mtundu wa tag yoyenera RFID , kukhathamiritsa kapangidwe ka tinyanga, ndikuganizira malo omwe mukufuna kugwiritsa ntchito. Kukonzekera koyenera kumatsimikizira kuti makhadi amagwira ntchito modalirika komanso mogwira mtima pazochitika zawo zogwiritsidwa ntchito.
Kupita patsogolo kwamtsogolo muukadaulo wa RFID kukuyembekezeka kupititsa patsogolo luso lowerenga patali. Kupititsa patsogolo kamangidwe ka tinyanga, kukonza ma siginecha, ndi kasamalidwe ka mphamvu zidzathandizira kuwerengera kwanthawi yayitali komanso machitidwe odalirika a RFID .
Kuphatikiza kwaukadaulo wa RFID ndi intaneti ya Zinthu (IoT) ndi zida zanzeru ndizomwe zikukula. Kulumikizana kumeneku kumathandizira kusonkhanitsa deta mwaukadaulo, kutsatira nthawi yeniyeni, ndi makina okhathamiritsa, kukulitsa kuthekera kowerengera kwa RFID 's kuwerengeka kwautali kwa machitidwe opambana komanso olumikizana.
RFID zolowetsa zonyowa pamakidi ndi zinthu zofunika kwambiri pakupanga makadi amakono, zomwe zimapereka magwiridwe antchito osiyanasiyana kudzera potumiza ma data opanda zingwe. Kumvetsetsa ndi kukonza mtunda wowerengera ndikofunikira pakuwonetsetsa kuti machitidwe a RFID akuyenda bwino komanso odalirika. Poganizira zinthu monga pafupipafupi, kapangidwe ka tinyanga, ndi momwe chilengedwe chimakhalira, opanga amatha kupititsa patsogolo mtunda wowerengera ndikukwaniritsa magwiridwe antchito osiyanasiyana. Pamene ukadaulo RFID ukupitilirabe kusinthika, kupita patsogolo pamapangidwe a tinyanga ndi kuphatikiza ndi IoT kumalonjeza kuthekera kokulirapo komanso kuchita bwino.
