Wireless radio frequency tekinoroji: ongororo yemisimboti uye yakawanda-munda application

RF (Radio Frequency) inoreva masaisai emagetsi ane frequencies pakati pe3kHz ne300GHz, ayo anoita basa rakakosha mukutaurirana, radar, kurapwa, kutonga kwemaindasitiri nemamwe minda.

Nheyo dzekutanga dzeredhiyo frequency

Masaini eRF anogadzirwa nemaoscillator, uye mafungu emagetsi emagetsi epamusoro anofambiswa uye kuparadzirwa kuburikidza nemaantenna. Mhando dzeantenna dzakajairwa dzinosanganisira dipole antennas, nyanga antennas uye chigamba antennas, ayo akakodzera akasiyana ekushandisa mamiriro. Iyo yekupedzisira inogashira inodzoreredza iyo RF siginecha kune inoshandisika ruzivo kuburikidza nedemodulator kuti uwane ruzivo rwekufambisa.

Kuronga uye modulation nzira dzeredhiyo frequency

Zvinoenderana nefrequency, redhiyo frequency inogona kukamurwa kuita yakaderera frequency (sekutepfenyura kutaurirana), yepakati frequency (senge nharembozha), uye yakakwirira frequency (senge radar uye kurapwa). Nzira dzekushandura dzinosanganisira AM (yekutapurirana kwakaderera), FM (yepakati-kumhanya kufambisa) uye PM (yekumhanyisa data data).

RFID: iyo yakakosha tekinoroji yekuzivikanwa kwehungwaru

RFID (radio frequency identification) inoshandisa electromagnetic waves uye microchips kuwana otomatiki chiziviso, uye inoshandiswa zvakanyanya mukuzivikanwa chitupa, manejimendi manejimendi, kurima nekuchengeta mhuka, kubhadhara kwekufambisa uye mamwe minda. Kunyangwe tekinoroji yeRFID yakatarisana nematambudziko akadai semutengo uye kumisikidza, kurerukira kwayo uye kushanda nesimba kwakasimudzira kuvandudzwa kwehungwaru manejimendi.

Kushandiswa kwakakura kweRF tekinoroji

RF tekinoroji inopenya muminda yekutaurirana isina waya, setiraiti kutaurirana, kuona radar, kuongororwa kwekurapa uye kutonga kwemaindasitiri. Kubva paWLAN network kusvika kuelectrocardiographs, kubva munhandare yehondo kubvunzurudzwa kuenda kumafekitori akangwara, tekinoroji yeRF iri kusimudzira kufambira mberi kwetekinoroji uye nekuchinja mararamiro edu.

Kunyangwe tekinoroji yeRF ichiri kutarisana nematambudziko, nekuvandudzwa kwesainzi uye tekinoroji, icharamba ichipaza hunyanzvi uye kuunza mimwe mikana yeramangwana!
