Chii chinonzi Rfid Electronic Tag?

RFID electronic tags anoshandiswa zvakanyanya muhupenyu hwezuva nezuva hwemunhu wese uye zviitiko zvekugadzira. Haingonatsiridza zvakanyanya kushanda kwekugadzira, asi zvakare inounza kurerukirwa kwakawanda kuhupenyu hwezuva nezuva hwevanhu. Saka nhasi ini ndichasuma RFID emagetsi tags kwauri.

Mashandisiro anoita RFID ma tag emagetsi

RFID ma tag anoshandisa isina waya redhiyo frequency kuita isingabatane nzira mbiri-dhata kufambisa pakati pemuverengi neredhiyo frequency kadhi kuzadzisa chinangwa chekuzivikanwa uye kuchinjana data. Chekutanga, mushure mekunge iyo RFID yemagetsi tag yapinda mune magineti, inogamuchira redhiyo frequency chiratidzo inotumirwa nemuverengi, uye yobva yashandisa Iyo simba rinowanikwa neiyo induced ikozvino inotumira iyo chigadzirwa ruzivo rwakachengetwa mu chip (passive tag kana passive tag), kana iyo tag inoshingairira kutumira chiratidzo cheimwe frequency (inoshanda tag kana inoshanda tag), uye muverengi anoverenga ruzivo uye anoitsanangura. Chekupedzisira, inotumirwa kune yepakati ruzivo system kune yakakodzera data kugadzirisa.

Iko kuumbwa kweRFID yemagetsi tags

Iyo yakazara RFID yemagetsi tag ine zvikamu zvitatu: muverengi / munyori, tegi yemagetsi, uye data management system. Nheyo yayo yekushanda ndeyekuti iyo Reader inoburitsa radio wave simba reiyo frequency kutyaira dunhu kutumira iyo yemukati data. Panguva ino, Muverengi sequentially Gamuchira uye kududzira data uye itumire kune iyo application yekuenderana kugadzirisa.

1. Muverengi

Muverengi mudziyo unoverenga ruzivo rwuri muRFID yemagetsi tag kana kunyora ruzivo rwunoda kuchengetwa muteki. Zvichienderana nechimiro uye tekinoroji inoshandiswa, muverengi anogona kuve chiverengero chekuverenga / kunyora uye ndiyo inodzora ruzivo uye nzvimbo yekugadzirisa yeRFID system. Kana iyo RFID system iri kushanda, muverengi anotumira redhiyo frequency simba mukati menzvimbo kuti igadzire munda wemagetsi. Kukura kwenzvimbo kunoenderana nesimba rekutapurirana. Mategi mukati menzvimbo yekuvhara yevaverengi anokonzereswa, tumira iyo data yakachengetwa mavari, kana shandura iyo data yakachengetwa mavari zvinoenderana nemirairo yemuverengi, uye inogona kutaurirana netiweki yekombuta kuburikidza neiyo interface. Izvo zvakakosha zvemuverengi zvinowanzo sanganisira: transceiver antenna, frequency jenareta, phase-yakiyiwa loop, modulation circuit, microprocessor, memory, demodulation circuit uye peripheral interface.

(1) Transceiver antenna: Tumira masaini eredhiyo kumatagi, uye gamuchira masaini ekupindura uye tag ruzivo rwakadzoserwa nema tag.

(2) Frequency jenareta: inogadzira iyo frequency yekushandisa system.

(3) Phase-yakakiyiwa loop: gadzira inodiwa inotakura chiratidzo.

(4) Modulation dunhu: Rodha chiratidzo chakatumirwa kune teki mune inotakura wave uye woitumira kunze neredhiyo frequency circuit.

(5) Microprocessor: inogadzira chiratidzo kuti itumirwe kune tag, inosarudza chiratidzo chakadzoserwa neti, uye inotumira iyo decoded data kuchirongwa chekunyorera. Kana iyo system yakavharidzirwa, inodawo kuita decryption oparesheni.

(6) Memory: zvitoro zvevashandisi zvirongwa uye data.

(7) Demodulation circuit: Demodulates chiratidzo chakadzoserwa netiki uye inotumira kune microprocessor kuti igadziriswe.

(8) Peripheral interface: inotaurirana nekombuta.

2. Electronic label

Mategi emagetsi anoumbwa ne transceiver antennas, AC/DC maseketi, demodulation circuits, logic control circuits, memory uye modulation circuits.

(1) Transceiver antenna: Gamuchira masaini kubva kumuverengi uye tumira iyo inodiwa data kumashure kumuverengi.

(2) AC/DC dunhu: Inoshandisa magetsi emagetsi emumunda anoburitswa nemuverengi uye anoaburitsa kuburikidza nevoltage inodzikamisa dunhu kuti ipe simba rakagadzikana kune mamwe maseketi.

(3) Demodulation circuit: bvisa mutakuri kubva kune yakagamuchirwa chiratidzo uye demodulate chiratidzo chepakutanga.

(4) Logic control circuit: inobvisa chiratidzo kubva kumuverengi uye inotumira kumashure chiratidzo zvinoenderana nezvinodiwa nemuverengi.

(5) Memory: mashandiro ehurongwa uye kuchengetwa kwedata rekuzivikanwa.

(6) Modulation wedunhu: Iyo data inotumirwa neiyo logic control circuit inotakurwa muantenna uye inotumirwa kumuverengi mushure mekuiswa mukati modulation wedunhu.

Hunhu hweRFID dzemagetsi tags

Kazhinji kutaura, radio frequency identification tekinoroji ine zvinotevera maitiro:

1. Kushanda

RFID tag tekinoroji inotsamira pamafungu emagetsi uye haidi kubata kwemuviri pakati pemapato maviri. Izvi zvinoibvumira kumisikidza kubatanidza uye kupedzisa kutaurirana zvakananga zvisinei neguruva, mhute, plastiki, bepa, huni uye zvakasiyana zvipingamupinyi.

2. Kubudirira

Iyo yekumhanyisa yekuverenga nekunyora yeRFID yemagetsi tag system inokurumidza zvakanyanya, uye yakajairwa RFID yekufambisa maitiro kazhinji inotora isingasviki zana milliseconds. High-frequency RFID vaverengi vanogona kunyange kuona uye kuverenga zviri mukati memategi akawanda panguva imwe chete, zvichivandudza zvakanyanya kushanda kwekufambisa ruzivo.

3. Uniqueness

Imwe neimwe RFID tag yakasarudzika. Kuburikidza nekunyorerana-kune-mumwe pakati peRFID tag uye zvigadzirwa, iyo inotevera kutenderera kwechigadzirwa chimwe nechimwe inogona kuteedzerwa zvakajeka.

4. Kupfava

RFID ma tag ane chimiro chakareruka, mwero wekuzivikanwa wakakwira, uye zviri nyore zvekuverenga. Kunyanya sezvo tekinoroji yeNFC ichiwedzera kufarirwa pamafoni efoni, nharembozha yemushandisi wese inova muverengi akareruka weRFID.

Pane ruzivo rwakawanda nezve RFID yemagetsi tags. Joinet yakatarisana nekutsvagisa uye kusimudzira kwakasiyana matekinoroji epamusoro kwemakore mazhinji, yakabatsira kusimudzira makambani mazhinji, uye yakazvipira kuunza zvirinani RFID yemagetsi tag mhinduro kune vatengi.
