Khoom Description
Ultrasonic av nkos dej interface ntsuas yog nqa tawm los ntawm ib tug ultrasonic sensor ntsia rau hauv dej, uas emits ib tug nqaj ntawm ultrasonic mem tes mus rau hauv qab dej av nkos nto. Qhov teeb liab mem tes no tau rov qab los thaum nws ntsib cov av nkos thiab tuaj yeem tau txais los ntawm lub sensor dua; Lub sij hawm los ntawm ultrasonic emission rau txais tos yog proportional rau qhov kev ncua deb ntawm lub sensor mus rau saum npoo ntawm cov khoom ntsuas; Lub ntsuas ntsuas ntsuas lub sijhawm thiab suav qhov kev ncua deb (piv txwv li spatial nrug) nruab nrab ntawm qhov chaw ntawm qhov khoom raug ntsuas thiab ntsuas ntsuas raws li qhov ntsuas kub tam sim no ( ntsuas los ntawm lub sensor) thiab qhov ceev ntawm lub suab hauv qab dej, thiab ntxiv hloov mus rau cov kua. qib tus nqi. Qhov deb ntawm dej hauv qab W ntawm cov kua dej ntws ncaj qha rau lub sijhawm mus ncig T ntawm lub suab nthwv dej: W=V × T / 2 (qhov twg V yog qhov nrawm ntawm lub suab nthwv dej hauv dej). Tus neeg siv teeb tsa qhov siab H los ntawm kev sojntsuam mus rau hauv qab ntawm lub pas dej, thiab lub ntsuas ntsuas tau hloov lub sijhawm mus ncig ntawm lub plawv T rau hauv qhov sib npaug ntawm qhov sib npaug ntawm tus nqi W, thiab tom qab ntawd suav qhov sib txawv ntawm H thiab W kom tau txais qhov ntsuas L.
