Chidziwitso cha Ultrasonic Sensors
Masensa akupanga ndi masensa omwe amapangidwa pogwiritsa ntchito mawonekedwe a ultrasound.Akupanga masensa ntchito piezoelectric zotsatira za piezoelectric ceramics.Chizindikiro chamagetsi chikagwiritsidwa ntchito pa mbale ya piezoelectric ceramic, imapunduka, zomwe zimapangitsa kuti sensa igwedezeke ndikutulutsa mafunde akupanga.ultrasound ikagunda chopinga, imayang'ana mmbuyo ndikuchitapo kanthu pa mbale ya piezoelectric ceramic kudzera mu sensa.Kutengera mphamvu ya piezoelectric inverse, sensor ya ultrasound imatulutsa chizindikiro chamagetsi.Pogwiritsa ntchito mfundo ya kufalikira kosalekeza kwa mafunde akupanga mu sing'anga yomweyo, mtunda wapakati pa zopinga ukhoza kutsimikiziridwa potengera kusiyana kwa nthawi pakati pa kutumiza ndi kulandira zizindikiro.Akupanga mafunde adzapanga kwambiri kusinkhasinkha mwamawu akakumana ndi zosafunika kapena interfaces, ndi Doppler zotsatira akakumana ndi kusuntha zinthu.Chifukwa chake, masensa akupanga amagwiritsidwa ntchito kwambiri m'mafakitale, kugwiritsa ntchito anthu wamba, chitetezo cha dziko, biomedicine, ndi zina.
Mapulogalamu
1. Magalimoto odana ndi kugunda radar, akupanga kuyambira dongosolo, akupanga moyandikana lophimba;
2. Zipangizo zowongolera zakutali za zida zapakhomo, zoseweretsa, ndi zida zina zamagetsi;
3. Akupanga kutulutsa ndi kulandirira zida zotsutsana ndi kuba ndi zida zopewera masoka.
4.Used kuthamangitsa udzudzu, tizilombo, nyama, etc.
Zidziwitso
1. The akupanga emitter limatulutsa akupanga mtengo pa 60 digiri ngodya kunja, kotero pasakhale zopinga zina pakati kafukufuku ndi kuyeza chinthu.
2. The akupanga gawo amayesa ofukula mtunda pakati pa chinthu choyezedwa ndi kafukufuku, ndi kafukufuku ayenera kusungidwa moyang'anizana ndi chinthu kuyeza pa muyeso.
3. Kuyeza kwa akupanga kumakhudzidwa ndi liwiro la mphepo ya chilengedwe, kutentha, ndi zina zotero.
Nkhani zotheka
1. Chifukwa cha chikoka cha kusalinganika kwa chinthu choyezedwa, kuwunikira kolowera, liwiro la mphepo yamkuntho ndi kutentha, ndi mawonedwe angapo, mafunde akupanga amatha kuwonjezera zolakwika za data.
2. Chifukwa cha makhalidwe achibadwa a ultrasound pakuyeza madontho akhungu, ngati malo oyezera asintha ndipo deta yolandilidwa imakhalabe yosasinthika panthawi ya kuyeza kwapafupi, zimasonyeza kuti malo osawona a muyeso alowetsedwa.
3. Ngati palibe deta yoyezera yomwe imabwezeretsedwa pamene gawo likuyesa zinthu zakutali, likhoza kukhala kunja kwa miyeso kapena mbali yoyezera ikhoza kukhala yolakwika.Mbali yoyezera imatha kusinthidwa moyenera.
