Alaarmiga ka-hortagga tuugada ee Ultrasonic, codsi digniin ka-hortagga xatooyada garaadka leh

█Hordhac

Adeegsiga dareemaha ultrasonic sida gudbiyaha iyo qaataha, gudbiyaha waxa uu ku sii daayaa mawjadda Ultrasonic amplitude siman aagga la ogaaday iyo qaataha waxa uu helayaa mowjadda ultrasonic ka muuqata, marka aanay jirin shay u dhaqaaqaya aagga la ogaaday, mawjada ultrasonic ka muuqata waa baaxad siman . Marka uu jiro shay u guuraya aagga ogaanshaha, baaxadda mawjada ultrasonic ee muuqata way kala duwan tahay oo isbeddelaysaa si joogto ah, iyo wareegga helitaanka ayaa ogaanaya calaamadda isbeddelka si loo xakameeyo wareegga si ay uga falceliso, taas oo ah, in la wado qaylo-dhaanta.

Marka loo eego qaab dhismeedka iyo hababka rakibaadda waxaa loo qaybiyaa laba nooc: mid waa rakibidda laba transducers ultrasonic ee isku guri, taas oo ah, transceiver iyo gudbiyaha nooca la isku daray, mabda'a shaqada ay ku salaysan tahay saamaynta Doppler ee hirarka dhawaaqa, sidoo kale loo yaqaan nooca Doppler. Marka shay dhaqaaqa uusan soo galin aagga la ogaaday, hirarka ultrasonic ee ka muuqda waa baaxad siman. Marka shay dhaqaaqa uu galo aagga la ogaaday, ultrasound-ka muuqda waa baaxad weyn oo aan sinnayn oo si joogto ah isbeddela. Qaybinta goobta tamarta ee ultrasound-ka la sii daayay waxay leedahay jihayn gaar ah, guud ahaan aagga jihada u jeedda ee qaybinta tamarta elliptical.

Midda kale waa labada transducer oo lagu meeleeyay meelo kala duwan, taas oo ah, helida iyo gudbinta nooca kala qaybsan, oo loo yaqaan ' sound field detector', gudbiyeheeda iyo qaataha ayaa u badan kuwa aan jiho ahayn (ie omnidirectional) transducer ama nooca nus-way transducer. Beddeliyaha aan jihada ahayn wuxuu soo saaraa qaabka qaybinta tamarta hemispherical iyo nooca jiho-jiho ah wuxuu soo saaraa qaabka qaybinta goobta tamarta kolayga.

Qalabka Ultrasonic ee ogaan kara walxaha dhaqaaqa waxay leeyihiin codsiyo badan oo kala duwan, tusaale ahaan, furitaanka albaabka tooska ah iyo xidhitaanka ogaanshaha iyo xakamaynta; kicinta tooska ah ee bilawga ah; Qalabka digniinta ka hortagga xatooyada, iwm. Sifada qalabkan ayaa ah in uu xukumi karo haddii ay jiraan xayawaan firfircoon ama walxo kale oo dhaqaaqa goobta la ogaaday. Waxay leedahay wareeg weyn oo xakameyn ah iyo isku halaynta sare.
