Ultrasonic anti-tub sab tub nyiag tswb, ntse tiv thaiv tub sab tswb daim ntawv thov

█Taw qhia

Siv lub ultrasonic sensor raws li lub transmitter thiab receiver, lub transmitter emits ib tug sib npaug amplitude ultrasonic yoj mus rau qhov chaw kuaj pom thiab lub receiver tau txais lub reflected ultrasonic yoj, thaum tsis muaj ib tug txav khoom mus rau hauv lub cheeb tsam, lub reflected ultrasonic yoj yog sib npaug zos amplitude. . Thaum muaj ib qho khoom txav mus rau hauv qhov chaw kuaj pom, qhov cuam tshuam ntawm ultrasonic nthwv dej amplitude sib txawv thiab hloov tas li, thiab qhov tau txais Circuit Court pom cov teeb liab hloov los tswj lub Circuit Court kom hnov ​​​​mob, uas yog, tsav lub tswb.

█Working txoj cai ntawm ultrasonic anti-tub sab tub nyiag tswb

Raws li nws cov qauv thiab kev teeb tsa tau muab faib ua ob hom: ib qho yog kev teeb tsa ntawm ob lub ultrasonic transducers nyob rau hauv tib lub tsev, uas yog, transceiver thiab transmitter ua ke hom, nws txoj haujlwm ua haujlwm yog raws li Doppler nyhuv ntawm lub suab tsis, thiab hu ua Doppler type. Thaum tsis muaj cov khoom txav mus rau hauv qhov chaw kuaj pom, qhov cuam tshuam ultrasonic tsis muaj qhov sib npaug. Thaum ib qho khoom txav nkag mus rau hauv qhov chaw kuaj pom, qhov pom ntawm ultrasound yog qhov tsis sib xws thiab hloov pauv tas li. Lub zog teb kev faib tawm ntawm lub emitted ultrasound muaj ib tug tej yam directionality, feem ntau rau cov kev taw qhia-ntsib cheeb tsam nyob rau hauv ib tug elliptical zog teb tis.

Lwm qhov yog ob lub transducers tau muab tso rau hauv ntau txoj haujlwm, uas yog, tau txais thiab xa cov khoom sib cais, lub npe hu ua lub suab thaj chaw ntes, nws cov transmitter thiab receiver feem ntau tsis yog kev taw qhia (ie omnidirectional) transducer lossis ib nrab-txoj kev transducer. Cov tsis-directional transducer tsim ib hemispherical zog teb faib qauv thiab cov semi-directional hom ua ib tug conical zog teb faib qauv.

█Cov cheeb tsam siv los tiv thaiv tub sab tub nyiag tswb.

Ultrasonic detectors uas tuaj yeem ntes cov khoom txav mus los muaj ntau yam kev siv, piv txwv li, tsis siv neeg lub qhov rooj qhib thiab kaw kom pom thiab tswj; tsis siv neeg nqa pib pib; anti-tub sab tub nyiag tswb ntes, thiab lwm yam. Cov yam ntxwv ntawm lub ntes no yog tias nws muaj peev xwm txiav txim seb puas muaj tib neeg cov tsiaj los yog lwm yam khoom txav mus los hauv qhov chaw kuaj pom. Nws muaj ib tug loj tswj ncig thiab muaj kev ntseeg siab.
