Abstract
Prvi ultrazvučni mjerač udaljenosti stvoren je 1959. godine od strane Satomure. U praksi danas postoje četiri temeljne vrste ultrazvučnih mjerača; doppler, radar, ultrazvučna stezaljka te ultrazvučni odašiljač razine. Svi ultrazvučni mjerači udaljenosti rade tako što odašilju zvučni val na frekvenciji iznad raspona ljudskog sluha. Pritom koriste sondu za slanje impulsa i primanje eha, a senzor određuje udaljenost do cilja mjerenjem vremenskih intervala između slanja i primanja ultrazvučnog impulsa. Ultrazvučni mjerači udaljenosti prikladni su za detekciju blizine do deset metara i pružaju višestruka mjerenja raspona u sekundi. Njih odlikuje niska razina potrošnje energije te činjenica da oni mogu raditi u mnogim uvjetima okoline. Za izradu uobičajenog ultrazvučnog mjerača udaljenosti koristi se step down transformator, elektrolitički kondenzator, diode, otpornik, mikrokontroler, kristalni oscilator te ultrazvučni senzor. Prednosti ultrazvučnih mjerača udaljenosti su sposobnost mjerenja prozirnih objekata, uključujući površinu vode te nisku nabavnu cijenu. Ipak, ultrazvučni mjerači udaljenosti najbolje rade u praznim sobama ili na otvorenom, imaju vrlo nisku točnost te im je ograničena upotreba u inženjerskim aplikacijama. Za daljnja istraživanja se preporuča dodatno istraživanje ove tematike.
Abstract (english)
The first ultrasonic distance meter was created in 1959 by Satomura. In practice today, there are four basic types of ultrasonic meters; doppler, radar, ultrasonic clamp and ultrasonic level transmitter. All ultrasonic rangefinders work by emitting a sound wave at a frequency above the range of human hearing. They use a probe to send the pulse and receive the echo, and the sensor determines the distance to the target by measuring the time intervals between sending and receiving the ultrasonic pulse. Ultrasonic rangefinders are suitable for detecting proximity up to ten meters and provide multiple range measurements per second. They are characterized by low energy consumption and the fact that they can work in many environmental conditions. A step down transformer, electrolytic capacitor, diode, resistor, microcontroller, crystal oscillator and ultrasonic sensor are used to make the usual ultrasonic distance meter. The advantages of ultrasonic distance meters are the ability to measure transparent objects, including the water surface, and the low purchase price. However, ultrasonic rangefinders work best in empty rooms or outdoors, have very low accuracy, and are limited in use in engineering applications. For further research, additional research on this topic is recommended.
