Basa rakakosha reRFID antenna muRFID system
Kanyanga yeRfid imhando yemushanduri, uyo unoshandura wave inotungamirwa inopararira pamutsetse wekutumira kuita electromagnetic wave inopararira munzvimbo isina muganho (kazhinji nzvimbo yakasununguka), kana kuita shanduko yakapesana. Senhengo yakakosha yemhuri yeantenna, RFID antenna inoita basa rakakosha muRFID system:
Nheyo yeRFID antenna yakavakirwa patekinoroji yekutaurirana neredhiyo, iyo antenna inogamuchira uye inoburitsa masaini emagetsi emagetsi kuti ione kuverenga nekunyora kwemashoko akachengetwa mu tag. Kunyanya, RFID antenna chishandiso chinotumira uye chinogamuchira masaini eRF carrier. Kana frequency yekushanda uye bandwidth zvatsanangurwa, antenna inotumira RF carrier inogadzirwa neRF processing module uye inogamuchira RF carrier inoburitswa kana kuratidzwa kubva mu tag.
Aya masaini eRF carrier ndiwo hwaro hweRFID system kuti ikwanise kuzivikanwa kwewaya isina waya uye kuchinjana data.
Mabasa makuru eRFID antenna anosanganisira:
Masaini ekutumira: Antena yeRFID ndiyo inokonzeresa masaini eRF anogadzirwa nemuverengi muchimiro chemafungu emagetsi anoburitswa. Masaini aya ane mirairo chaiyo nesimba, zvinoshandiswa kuvhura nekutaurirana ne Tag yeRfids. RFID system yakasiyana-siyana, antenna inotumira masaini emagetsi yakasiyana. Magadzirirwo uye mashandiro eantenna anokanganisa zvakananga simba negwara remasaini anotumirwa. Antenna yakagadzirwa zvakanaka inogona kutarisisa chiratidzo munzira chaiyo, ichivandudza kufukidzwa kwechiratidzo uye kushanda zvakanaka kwekutumira.
Gamuchira zviratidzo: kana RFID tag ikagamuchira chiratidzo chinotumirwa nemuverengi, ichapindura chiratidzo ichi kuburikidza neantenna yayo pachayo kumuverengi. RFID antenna ndiyo ine basa rekugamuchira zviratidzo izvi kubva ku tag, uye ichatumirwa kumuverengi kuti agadziriswe. Antena inogamuchira kunzwisisika uye kugona kudzivirira kukanganiswa kwekugamuchira chiratidzo che tag nemazvo kwakakosha. Antena ine kunzwisisika kwakanyanya inogona kugamuchira zviratidzo zve tag zvisina simba, uye kugona kwakanaka kwekudzivirira kukanganiswa kunogona kuderedza kukanganiswa kubva munzvimbo yakapoteredza, kuvandudza kunaka kwechiratidzo.
Maitiro ekusarudza antenna yeRFID chaiyo
Kusarudza antenna yeRFID yakakodzera idanho rakakosha pakuona kuti sisitimu yeRFID inoshanda zvakanaka. Inotevera ndiyo sarudzo ye MaAntena eRfid Zvinoda kufunga nezvezvimwe zvezvinhu:
1.sarudzo yefrequency
Masisitimu eRFID anowanzo shanda mumabhendi matatu emafrequency: low frequency (LF), high frequency (HF) uye ultra-high frequency (UHF). Pakusarudza antenna, unofanira kutanga waona kuti RFID system yako ichashandisa frequency band ipi.
2. Mamiriro Ekushandisa
Sarudza antenna zvichienderana nemamiriro ekushandisa. Semuenzaniso, kana ikashandiswa mudura, antenna yekuverenga kure ingangodiwa; nepo mukutevera zvinhu zvidiki, antenna yerenji pfupi ingangove yakakodzera.
3. Kuwedzera kweAntena
Kukwira kweantenna kunokanganisa simba rechiratidzo uye daro rekuverenga. Antena ine gain yakakwira inogona kuverenga ma tag ari kure, asi mepu yegwara remwaranzi inogona kunge yakatetepa; antena ine gain yakaderera yakakodzera kuverenga zviri pedyo.
4. Rudzi rweAntena
Antena yakatsetseka: yakakodzera kuverenga ma tag pazvinhu zvakati sandara.
Antena yedenderedzwa polarization: haisati yanyatsojeka kuti inoshanda sei kune label direction, inogona kuvandudza mwero wekubudirira kwekuverenga.
Antena yepolarization yakatsetseka: yakakodzera kutungamira kwechinyorwa chinozivikanwa.
5. Nzira yekuisa
-Funga nezvenzira yekuisa antenna (yakadai seyakagadziriswa, inofambiswa, yakamboiswa mukati, nezvimwewo), kuti uve nechokwadi chekuti antenna inogona kushanda zvinobudirira mukushandiswa chaiko.
6. Zvinhu zvakatipoteredza
Funga nezvenzvimbo ichashandiswa antenna (semuenzaniso, tembiricha, hunyoro, makemikari, nezvimwewo), uye sarudza zvinhu zvakakodzera uye magadzirirwo kuti uve nechokwadi chekuti antenna inogara kwenguva refu.
7. Rudzi rweTag
Mhando dzakasiyana dzematag (semuenzaniso matag asingashande, matag anoshanda) dzinogona kunge dziine zvinodiwa zvakasiyana paantenna. Iva nechokwadi chekuti antenna inoenderana netag iri kushandiswa.
8. Kuverenga Nguva
Sarudza antenna zvichienderana nedaro rekuverenga rinodiwa, shandisa antenna ine gain yakakwira pakuverenga kure uye antenna ine gain yakaderera pakuverenga kure.
9. Mutengo
Sarudza antenna inokodzera bhajeti yako. Ma antenna anoshanda zvakanaka anowanzo kudhura, asi anogona kunge ari mari inodiwa mune mamwe maapplication.
Nekukurumidza kukura nekukurumidzisa kweInternet of things technology, RFID antenna sechikamu chakakosha cheInternet of things perception layer, mukodhi yekutanga, system yekutarisira asset inewo nzvimbo isingatsiviwe, parizvino kune akasiyana-siyana emitemo uye maprotocol eRFID technology, ayo kusvika pamwero wakati anoderedza chiyero chekushandiswa kwayo. Mune ramangwana, nekukura kuri kuramba kuchienderera mberi kwetekinoroji uye kudiwa kwemusika, RFID antenna inotarisirwa kuwana standardization uye compatibility enhancement, kuderedza application threshold, kukurudzira popularization uye application yeRFID technology!
