Tus ntsuas ultrasonic (nrug) yog dab tsi? Ib qho ultrasound (Sonar) nrog cov nthwv dej siab uas tib neeg tsis hnov. Txawm li cas los xij, peb tuaj yeem pom pom muaj cov nthwv dej ultrasonic nyob txhua qhov chaw. Hauv cov tsiaj xws li puav, ntses taub ntswg ntev … siv ultrasonic nthwv dej sib txuas lus nrog lwm tus, yos hav zoov lossis nrhiav chaw.
Khoom siv:
Code: Rub tawm
Kauj Ruam 1: Ultrasonic Sensor (HC - SRF04)
Ultrasonic sensor HC-SR04 (Ultrasonic Sensor) yog siv nrov heev los txiav txim qhov nrug vim tus nqi pheej yig thiab raug heev. HC -SR04 ultrasonic sensor siv ultrasonic nthwv dej thiab tuaj yeem ntsuas qhov nrug ntawm 2 -> 300cm.
Kauj Ruam 2: Txoj Cai Ua Haujlwm
Txhawm rau ntsuas qhov nrug, peb yuav tso lub mem tes luv luv (5 microSeconds) los ntawm Trig pin. Tom qab ntawd, lub ntsuas hluav taws xob ultrasonic yuav tsim kom muaj HIGH mem tes ntawm Echo tus taw kom txog thaum nws tau txais lub teeb pom kev zoo ntawm lub roj teeb no. Qhov dav ntawm cov mem tes yuav sib npaug rau lub sijhawm ultrasonic yoj kis los ntawm lub sensor thiab sab nraub qaum. Qhov nrawm ntawm lub suab hauv huab cua yog 340 m / s (lub cev tsis tu ncua), sib npaug rau 29, 412 microSeconds / cm (106 / (340 * 100)). Thaum lub sijhawm xam xam, peb faib los ntawm 29, 412 kom tau txais qhov nrug deb.
Nco tseg: Qhov ntsuas ultrasonic ntau ntxiv yog, qhov tsis raug nws yuav raug ntes, vim tias lub kaum sab xis ntawm lub ntsuas yuav maj mam nthuav tawm hauv lub khob hliav qab, ntxiv rau oblique lossis ntxhib nto, nws yuav txo qhov raug ntawm lub ntsuas thiab ntsuas. Cov txheej txheem teev tseg hauv qab no yog los ntawm cov chaw tsim khoom ntawm kev sim hauv cov xwm txheej zoo, tab sis qhov tseeb nyob ntawm qhov chaw ua haujlwm ntawm lub ntsuas cua.
