Isingeniso Sezinzwa ze-Ultrasonic
Izinzwa ze-Ultrasonic izinzwa ezakhiwe kusetshenziswa izici ze-ultrasound.Izinzwa ze-Ultrasonic zisebenzisa umphumela we-piezoelectric we-piezoelectric ceramics.Uma isignali kagesi isetshenziswa epuleti le-ceramic ye-piezoelectric, izokhubaza, ibangele inzwa ukuthi idlidlize futhi ikhiphe amagagasi e-ultrasonic.Uma i-ultrasound ishaya isithiyo, ikhombisa emuva futhi isebenza kupuleti le-ceramic le-piezoelectric ngokusebenzisa inzwa.Ngokusekelwe kumphumela we-piezoelectric ophambene, inzwa ye-ultrasound ikhiqiza okukhipha isignali kagesi.Ngokusebenzisa isimiso sejubane eliqhubekayo lokusakaza lamagagasi e-ultrasonic endaweni efanayo, ibanga phakathi kwezithiyo linganqunywa ngokusekelwe kumehluko wesikhathi phakathi kokudlulisa nokwamukela amasignali.Amagagasi e-Ultrasonic azokhiqiza ama-reflection echoes abalulekile lapho ehlangana nokungcola noma ukuxhumana, kanye nemiphumela ye-Doppler lapho ehlangana nezinto ezihambayo.Ngakho-ke, izinzwa ze-ultrasonic zisetshenziswa kabanzi ezimbonini, ukusetshenziswa kwezakhamuzi, ukuvikela izwe, i-biomedicine, nakweminye imikhakha.
Izinhlelo zokusebenza
1. I-radar ye-Automotive anti-collision, i-ultrasonic esukela uhlelo, i-ultrasonic proximity switch;
2. Imishini yokulawula kude yemishini yasendlini, amathoyizi, nezinye izinto zikagesi;
3. Ukukhishwa kwe-Ultrasonic kanye nemishini yokwamukela imishini yokulwa nokweba kanye neyokuvimbela izinhlekelele.
4.Isetshenziselwa ukuxosha omiyane, izinambuzane, izilwane, njll.
Izaziso
1. I-emitter ye-ultrasonic ikhipha umsebe we-ultrasonic nge-engeli engu-60 degree ngaphandle, ngakho akufanele kube khona ezinye izithiyo phakathi kwe-probe nento elinganisiwe.
2. Imojula ye-ultrasonic ikala ibanga eliqondile phakathi kwento elinganisiwe kanye ne-probe, futhi i-probe kufanele igcinwe ibheke into elinganisiwe ngesikhathi sokulinganisa.
3. Ukulinganisa kwe-Ultrasonic kuthonywa isivinini somoya semvelo, izinga lokushisa, njll.
Izinkinga ezingenzeka
1. Ngenxa yethonya lokungalingani kwento elinganisiwe, i-reflection angle, isivinini somoya wemvelo nezinga lokushisa, kanye nokuboniswa okuningi, amagagasi e-ultrasonic angase andise amaphutha edatha yokulinganisa.
2. Ngenxa yezici ezingokwemvelo ze-ultrasound ekulinganiseni izindawo eziyimpumputhe, uma isimo sokulinganisa sishintsha futhi idatha etholiwe ihlala ingashintshiwe phakathi nokulinganisa ibanga eliseduze, kubonisa ukuthi indawo eyimpumputhe yokulinganisa ifakiwe.
3. Uma ingekho idatha yokulinganisa ebuyiswayo lapho imojuli ikala izinto ezikude, ingase ibe ngaphandle kwebanga lokulinganisa noma i-engeli yokulinganisa ingase ingalungile.I-engeli yokulinganisa ingalungiswa ngendlela efanele.
