Ultrasonic sensing technology yog nce siv nyob rau hauv tsis siv neeg qhov rooj systems. Nws siv ultrasonic sensors los ntes cov kev ua ub no ntawm tib neeg lub cev lossis cov khoom, thiab txiav txim siab seb puas muaj teeb meem lossis cov neeg taug kev nyob ib puag ncig ntawm lub qhov rooj los ntawm emitting ultrasonic signals thiab tau txais kev cuam tshuam cov teeb liab. Cov thev naus laus zis no muaj kev hloov pauv tau zoo rau ib puag ncig thiab tuaj yeem muab kev ruaj ntseg thiab txhim khu kev ntseeg hauv ntau qhov chaw ib puag ncig.
Nyob rau hauv lub qhov rooj tsis siv neeg, ultrasonic sensing tshuab yog tsuas yog siv los soj ntsuam ib puag ncig kev hloov nyob ib ncig ntawm lub qhov rooj thiab xa cov ntaub ntawv mus rau qhov kev tswj ntawm lub qhov rooj tsis siv neeg kom nws muaj peev xwm teb tau nyob rau hauv lub sij hawm. Thaum ib tug neeg lossis cov khoom nkag mus rau hauv qhov chaw hnov, lub sensor yuav ntes thiab xa cov teeb liab, thiab tus maub los yuav qhib lub qhov rooj xauv tom qab tau txais cov teeb liab tso cai rau tib neeg hla. Thaum ib tug neeg lossis cov khoom tawm ntawm qhov chaw nkag mus, lub sensor yuav xa cov teeb liab rov qab, thiab tus maub los yuav kaw lub qhov rooj tam sim ntawd kom muaj kev nyab xeeb thiab txuag hluav taws xob.
Tsis tas li ntawd, ultrasonic sensing thev naus laus zis kuj tseem tuaj yeem ua ke nrog lwm yam kev paub txog thev naus laus zis, xws li infrared sensing, microwave radar sensing, thiab lwm yam, txhawm rau txhim kho kev nyab xeeb thiab cov neeg siv kev paub ntawm lub qhov rooj tsis siv neeg. Piv txwv li, ultrasonic sensors tuaj yeem siv ua ke nrog infrared sensors kom ua tiav cov txiaj ntsig zoo dua thiab muaj txiaj ntsig zoo.
Feem ntau, daim ntawv thov ntawm ultrasonic sensing tshuab nyob rau hauv tsis siv neeg lub qhov rooj tshuab muaj cov tswv yim zoo thiab muaj peev xwm ua lag luam. Nrog rau kev txhim kho kev tshawb fawb thiab thev naus laus zis thiab tib neeg cov kev xav tau nce ntxiv rau kev nyab xeeb, ultrasonic sensing tshuab yuav ua lub luag haujlwm tseem ceeb hauv cov qhov rooj tsis siv neeg, muab cov neeg muaj kev nyab xeeb, yooj yim dua thiab yooj yim mus ncig.
