RFID ma tag emagetsi anoumbwa nemategi, rfid vaverengi uye kuchengetedza data uye masisitimu ekugadzirisa.Zvinoenderana neakasiyana nzira dzekupa magetsi, RFID inogona kukamurwa kuita mhando nhatu: inoshanda RFID, semi-inoshanda RFID, uye passive RFID.Chiyeuchidzo chipu chine antenna.Ruzivo rwuri mu chip runogona kushandiswa kuona chinangwa.Basa guru nderokuziva zvinhu.
Musiyano uripo pakati peanoshanda, semi-inoshanda uye passive RFID tags sezvinotevera:
1. Pfungwa
Active rfid inofambiswa nebhatiri rakavakwa-mukati, chikamu chemagetsi tags anotsanangurwa neakasiyana emagetsi emagetsi ma tags, uye anowanzo tsigira kureba-kuzivikanwa RFID. uye passive RFID tags.Muzviitiko zvakawanda, inowanzopinda munzvimbo yakarara uye isingashande, uye haitumire masaini eRFID kune kunze kwenyika.Chete kana iri mukati meiyo activation siginecha yeyakakwira-frequency activator, iyo inoshanda tag ichaitwa uye inoshandaPassive rfid, ndiko kuti, iyo passive radio frequency tag inotora inotakura yekushanda modhi, ine anti-kupindira kugona, vashandisi vanogona kugadzirisa iyo kuverenga nekunyora kwe data yakajairwa, kushanda kwacho kuri nyore kwazvo mupuratifomu yakakosha yekushandisa, uye chinhambwe chekuverenga chinogona kusvika kupfuura mamita gumi.
2. Nheyo yekushanda
Active electronic tag zvinoreva kuti simba rebasa remaki rinopihwa nebhatiri.Bhatiri, ndangariro uye antenna pamwe chete zvinoumba tegi yemagetsi inoshanda.Yakasiyana neiyo activation fomu ye passive radio frequency, iyo inoshanda RFID inoshongedzerwa neyakazvimiririra yekuchengetedza chinhu mukati.Simba rakazara, uye uchiri kutumira ruzivo nekuseta frequency bhendi bhatiri risati ratsiviwa.
Active ma tag ane hombe yekushanda chinhambwe, hombe yekuchengetera, uye yakasimba komputa simba nekuda kwekuenderera kwavo kwesimba rekupa, uye vanogona kushingaira kutumira zvikwangwani zvine ruzivo rwekupindirana pama frequency chaiwo kumuverengi.Kuvimbika kwekushanda kwakakwira, uye chiratidzo chekufambisa chinhambwe chakareba.Nekudaro, nekuda kwekupesvedzera kwesimba rebhatiri, hupenyu hwema tag anoshanda hushoma, kazhinji makore 3-10 chete.Nekushandiswa kwesimba rebhatiri mune tag, chinhambwe chekufambisa data chinova chidiki uye chidiki, izvo zvinokanganisa kushanda kwakajairika kweRFID system.
Semi-inoshanda rfid, akajairika anoshanda emagetsi tags anoshanda mu433M frequency bhendi kana iyo 2.4G frequency bhendi.Inoshanda zvakanaka mushure mekushandiswa.Iyo activation kureba ye-high-frequency activator inogumira, uye haigone kunyatso shandiswa mudiki diki uye diki renji.Nenzira iyi, iyo inoshanda tag inomisikidzwa neiyo yakaderera-frequency activator senzvimbo yekutanga, uye nzvimbo dzakasiyana dzepasi dzakaiswa munzvimbo dzakasiyana, uye ipapo hombe Nzvimbo inoshandisa muverengi kureba kuona uye kuverenga chiratidzo, uye wobva waisa chiratidzo kunzvimbo yekutungamira nenzira dzakasiyana dzekuisa.Nenzira iyi, iyo yese maitiro ekuunganidza chiratidzo, kutapurirana, kugadzirisa, uye kushandisa kunopedzwa.
Zvakafanana neiyo tag inoshanda, iyo semi-inoshanda tag inewo bhatiri mukati, asi bhatiri rinopa chete rutsigiro rwedunhu rinochengetedza data uye dunhu rinochengetedza kushanda kweiyo chip, uye inoshandiswa kutyaira iyo yakabatanidzwa dunhu. mukati me tag kuchengetedza mamiriro ekushanda.
Tisati tagi yemagetsi inopinda muhurumende yekushanda, yave iri mumhepo yakarara, iyo yakaenzana nekaiti yepasi.Iko kushandiswa kwesimba kwebhatiri mukati me tag idiki kwazvo, saka bhatiri rinogona kugara kwemakore akati wandei kana kunyange kusvika kumakore gumi.Kana iyo tegi yemagetsi ichipinda munzvimbo yekushanda yemuverengi, inokurudzirwa neredhiyo frequency sigiro inotumirwa nemuverengi, uye iyo tag inopinda munzvimbo yekushanda.Simba reiyo tag yemagetsi rinonyanya kuuya kubva kune redhiyo frequency simba remuverengi, uye bhatiri remukati reti rinonyanya kushandiswa kugadzira redhiyo frequency ndima.Simba risina kukwana.
Kuita kwepassive rfid tags kunokanganiswa zvakanyanya netag size, modulation nzira, wedunhu Q kukosha, kuita kwechishandiso uye kudzika kwemodulation.Passive tag haana yakavakirwa-mukati magetsi, uye anonyanya kufambiswa nematanda anotumirwa neRFID muverengi.
Kana redhiyo frequency chiratidzo chenzvimbo yemagetsi mune iyo tag yakasimba zvakakwana, iyo data data yakachengetwa mu chip inogona kutumirwa kumuverengi, kazhinji inosanganisira iyo tag identity ruzivo, chiziviso chinangwa kana data rakakodzera remuridzi. .
Kunyangwe chinhambwe chema tag emagetsi chipfupi, mutengo wakaderera, saizi idiki, hupenyu hwesevhisi hwakareba kwazvo, uye inogona kushanda munzvimbo dzakasiyana-siyana dzakaoma, uye inogona kusangana nezvinodiwa zveanonyanya kushanda masisitimu ekushandisa pasi peakasiyana. redhiyo mitemo.Inonyanya kushandiswa pamusika.
Ungasarudza sei RFID tag?
Anoshanda emagetsi ma tag ane chinhambwe chekushanda, uye chinhambwe chiri pakati peanoshanda eRFID tags uye RFID vaverengi vanogona kusvika makumi emamita, kana kunyange mazana emamita, asi zvichikanganiswa nebhatiri huwandu, hupenyu hupfupi, uye vhoriyamu yakakura uye mutengo. kumusoro.
Passive electronic tags madiki muhukuru, akareruka muhuremu, akaderera mumutengo uye akareba muhupenyu.Anogona kugadzirwa kuita maumbirwo akasiyana semashiti kana mabuckles, uye anoshandiswa munzvimbo dzakasiyana.Sezvo pasina simba remukati rekupa, chinhambwe chiri pakati pekungoita RFID tags uye RFID vaverengi ishoma, kazhinji mukati memamita mashoma kana anopfuura gumi metres, kazhinji inoda yakakwirira simba RFID vaverengi.
Semi-inoshanda RFID: Mutengo wacho uri pakati nepakati, asi basa racho idiki, uye zvinoshanda zvekushandisa zvinodiwa zvishoma.
