Iyo Anti-kupindira Mhedzisiro yeRFID Anti-metal Electronic Tag

Iyo Anti-kupindira Mhedzisiro yeRFID Anti-metal Electronic Tag

RFID anti-simbi yemagetsi tag, inozivikanwawo seyepamusoro-frequency anti-metal tag (zvinoenderana nezvinodiwa zveprojekiti uye nharaunda yekushandisa, inogona zvakare kugadzirwa kune yakaderera-frequency 125KHz/134.2KHz anti-simbi tag kana Ultra-yakakwirira-frequency 860 ~ 960MHz anti-simbi tag., uye inogona zvakare kugadzirirwa 2.45GHz inoshanda anti-simbi tag), itegi remagetsi rakagadzirwa nezvinhu zvinonwisa zvine anti-kupindira basa, iyo inogadzirisa zvinogadzirisa dambudziko reRF chiratidzo kupindira kwesimbi inotakura pane yemagetsi tag yakasungirirwa pamusoro wayo..
Iyo yekunze dhizaini yeRFID anti-simbi yemagetsi tag inoumbwa neFR-4 zvinhu, iyo yakaenzana nekuwedzera yakakosha anti-simbi inonwisa zvinhu pahwaro hwekutanga tag, kudzivirira kupindira kwezvinhu zvesimbi pachiratidzo che tag, iyo tag inewo anti-corrosion, isina mvura, acid-uchapupu hutatu-uchapupu basa, kukwirira kwekushisa kwepamusoro, kukanganisa kuramba, anti-collision, yakakodzera kune dzakasiyana siyana dzekushandisa hutsinye nharaunda.
RFID anti-simbi yemagetsi tag sechinhu chinonwisa muchikamu chekukanganisa kwechiratidzo

RFID anti-simbi emagetsi tag ane anonwisa zvinhu ane anotevera maitiro:

1. RFID anti-metal electronic tags inogona kuverenga yavo yakajairwa data nekugadzirisa kuvandudza kushanda kweiyo application system;
2. RFID anti-metal electronic tag kuverenga kure kure (kureba kwayo kwekuverenga nekunyora kune hukama neRFID muverengi uye antenna);
3. Super anti-kupindira kugona;
4. Nguva yakareba yekuchengetedza data, kusvika pa 20 makore, inodhura-inoshanda;
5. Multi-tag kuverenga, isina kukanganiswa uye kuganhurirwa nehuwandu hwema tag munzvimbo yebasa;
6. RFID anti-metal tag inotora Ultra-wide kushanda frequency bhendi dhizaini, iyo isingasangane chete nemitemo yakakodzera yeindasitiri, asi zvakare inogona kuvandudzwa uye kushandiswa;
7. Nzvimbo yekuchengetera inoshandiswa nevashandisi encrypt kuverenga, nyora, dzima uye nyora mashandiro, uye inogonawo kutsanangura nzvimbo yezwi yakatsaurirwa zvachose yevashandisi.

Nekuvandudzwa kweInternet yezvinhu, iko kushandiswa kwemafungu ekubata zvinhu muRFID tag kwave kwakajairika, uye RFID anti-metal electronic tags inoshandiswawo munzvimbo dzakasiyana siyana, kusanganisira logistics management, manejimendi ekuchengetedza zvinhu, asset management nedzimwe nzvimbo. Saka ndeipi basa rekutora zvinhu muRFID anti-metal tags?

MuRFID frequency renji, apo electromagnetic wave inosangana nepamusoro pesimbi, nekuda kweiyo eddy ikozvino phenomenon, yakasimba electromagnetic wave reflection inogadzirwa, uye pane mutsauko wechikamu pakati peinoratidzwa electromagnetic wave uye chiitiko wave, zvichiita kuti muwirirane kukanzura, panguva ino iyo chaiyo inoshanda magineti yemagetsi inokurumidza kuderedzwa, nokuti yakaderera resistivity yesimbi zvinhu, iyo yakakura kurasikirwa kwazvino eddy kuchakonzerwa, zvakanyanya kuoma dambudziko resimbi. Naizvozvo, kana waya iri pasi pekukanganiswa kwakanyanya kwesimbi, mirayiridzo yakabudiswa nemuverengi wekadhi ichanyangarika zvachose, saka mhedzisiro yekuverenga data yakundikana. Iyo wave inonwisa zvinhu inonyanya kushandisa hunhu hwepamusoro permeability. Kana yashandiswa, iyo wave inotora ndiro inoiswa pakati peiyo corrugated antenna yeRFID anti-metal tag uye simbi substrate kuwedzera mukana weiyo induced magineti inopfuura nepakati pesimbi ndiro kuburikidza ne wave inosveta zvinhu pachayo., nokudaro kuderedza chizvarwa che-induced eddy current mundiro yesimbi. Iyo wave inotora zvinhu zvino inoderedza kurasikirwa kweiyo induced magnetic field. Nekuda kwekuisa iyo inonwisa zvinhu separator, iyo yakayerwa parasitic capacitance ichaderedzwa zvakare, uye frequency offset ichaderedzwa, iyo inopindirana neresonance frequency yemuverengi wekadhi, nokudaro kuvandudza zvakanyanya kadhi kuverenga maitiro uye chinhambwe.

Mamwe mapurojekiti muhupenyu achasangana nenzvimbo dzakasiyana siyana, zvakadai sekushisa kwepamusoro uye kwakaderera, zvinwiwa, madziro esimende, simba remagineti, simbi zvichingodaro.
Semuyenzaniso, munzvimbo yesimbi, mu-ultra-high frequency (UHF) radio frequency identification tag system, kuzivikanwa kwetagi yakasungirirwa kune simbi inotakura inonyanya kuoma, nekuti zvipingamupinyi zvesimbi zvinoratidzira uye kukanganisa mafungu emagetsi. Parizvino, kune kunyanya nzira ina dzekugadzirisa zvinobudirira dambudziko rekubata ruzivo pamusoro pesimbi:
1. Iko kushandiswa kwezvinhu zvinonwisa kuti zvitore akawandisa emagetsi mafungu;
2. Padded urefu dhizaini;
3. Iyo bandwidth ye tag antenna inofanirwa kukwana;
4. Grounding mhando antenna dhizaini.
Parizvino, nzira yedu yakajairika ndeyekutora musanganiswa wezvinhu zvinonwisa uye padded urefu, uye nzira yakanaka ndeyekugadzira antenna ine bandwidth hombe, uye wobva washandisa zvinonwisa zvinhu kuti upedhe hurefu, iyo ichaita zvakanakisisa.
