Abstract
Određivanje položaja objekta putem ultrazvučnih senzora omogućava nam primjenu u mnogobrojnim granama znanosti, kao i u svakodnevnom životu. Većina materijala ima dobru sposobnost reflektiranja ultrazvučnih valova što omogućava njihovu detekciju. Princip rada UZ senzora temelji se na piezoelektričnom efektu, tj. pojavi električne polarizacije pri djelovanju mehaničkog naprezanja. Impulsi dovedeni na takav posebno odrezani kristal uzrokuju savijanje takvog materijala čija je posljedica generiranje ultrazvučnih valova. U ovom radu opisana je jednostavna izvedba ultrazvučnog sustava koja se sastoji od tri prijemnika i jednog odašiljača. Ostvarena je i bežična komunikacija razvojne okoline EZ430-RF2500 kojom je olakšana izvedba samog sustava. Spomenuta bežična komunikacija i generiranje impulsa tražene frekvencije ostvareno je pomoću IAR Embedded Workbench KickStart programske podrške, a preostale potrebe sustava izvedene su jednostavnim električnim komponentama, tj. jednostavnim električnim krugom. Dobiveni rezultati, koje smo prikazali na računalu pomoću akvizicijske kartice NI-USB6211, pokazali su nam način kojim se računa udaljenost objekta do odašiljača preko kašnjenja reflektiranog vala. To je osnovna ideja svih ultrazvučnih sustava čije implementacije mogu biti nešto jednostavnije ili složenije.
Abstract (english)
Determining the position of the object with ultrasonic sensors is used in many branches of science and also in everyday life. Most materials have ability of a good reflection of the ultrasonic waves what allows us to detect them. Principle of the ultrasonic sensors is based on the piezoelectric effect, on the electric polarization during mechanical stress. Impulses brought to the particularly cut crystal cause flexion of the material which then generates ultrasonic waves. In this work, it is described simple performance od the ultrasonic system which includes three receivers and one sender. Also, wireless communication has been established with EZ430-RF2500 which facilitates the performance of the system itself. Mentioned wireless communication and generating impulses with the required frequency has been established with IAR Embedded Workbench KickStart program support while the rest of the system was made of the simple electrical components. Given results, visible on the computer with data acquisition card NI-USB6211, showed us the way of computing distance between the object and the sender through the delay of the reflected wave. That's the basic idea of all ultrasonic systems which implementations can be simpler or more complex.
