Tekinoroji yeredhiyo isina waya: kuongorora nheyo uye kushandiswa kwenzvimbo dzakawanda

RF (Radio Frequency) inoreva mafungu emagetsi ane mafrequency ari pakati pe3kHz ne300GHz, ayo anoita basa guru mukutaurirana, radar, kurapwa, kutonga kwemaindasitiri nedzimwe nzvimbo.

Nheyo huru dzemafrequency eredhiyo

Masaini eRF anogadzirwa nemaoscillator, uye mafungu emagetsi ane frequency yakakwira anotumirwa uye anoparadzirwa kuburikidza nemaantenna. Mhando dzeantenna dzakajairika dzinosanganisira maantenna edipole, maantenna ehorn uye maantenna epatch, ayo akakodzera mamiriro akasiyana ekushandisa. Chikamu chinogashira chinodzosera chiratidzo cheRF kuruzivo runogona kushandiswa kuburikidza ne demodulator kuti chiwane kutapurirana kwemashoko.

Nzira dzekupatsanura uye modulation dzeredhiyo frequency

Zvichienderana nefrequency, radio frequency inogona kukamurwa kuita low frequency (senge kutaurirana kwenhepfenyuro), medium frequency (senge kutaurirana kwenharembozha), uye high frequency (senge radar nekurapwa). Nzira dzekushandura dzinosanganisira AM (yekutumira nekukurumidza), FM (yekutumira nekukurumidza) uye PM (yekutumira data nekukurumidza).

RFID: tekinoroji huru yekuziva nepfungwa

RFID (radio frequency identification) inoshandisa mafungu emagetsi nema microchips kuti iwane otomatiki identification, uye inoshandiswa zvakanyanya mukusimbisa hunhu, manejimendi yekufambisa, kurima nekuchengeta mhuka, kubhadhara kutakura nedzimwe nzvimbo. Kunyangwe tekinoroji yeRFID ichisangana nematambudziko akadai semutengo uye standardization, nyore kwayo uye kushanda kwayo kwakasimudzira kukura kwehungwaru hwekutarisira.

Kushandiswa kwakakura kwetekinoroji yeRF

Tekinoroji yeRF inoonekwa zvakanaka munhaurirano dzisina waya, kutaurirana nesatellite, kuona radar, kuongororwa kwezvirwere uye kudzora maindasitiri. Kubva kuma network eWLAN kusvika kuma electrocardiographs, kubva pakuferefeta nzvimbo dzehondo kusvika kumafekitori akangwara, tekinoroji yeRF iri kukurudzira kufambira mberi kwetekinoroji uye ichichinja mararamiro edu.

Kunyangwe tekinoroji yeRF ichiri kusangana nematambudziko, nekukura kwesainzi netekinoroji, icharamba ichibudirira mukuvandudza zvinhu zvitsva uye ichiunza mikana yakawanda mune ramangwana!
