Abstract
Ultrazvučni senzor je senzor koji služi za određivanje položaja objekta u prostoru temeljem ultrazvučnih valova i njihove fizikalne prirode. Princip rada ultrazvučnog senzora temelji se na piezoelektričnom efektu. Piezoelektrični efekt je pojava električne polarizacije u materijalu koji se savija pod pritiskom. Takav materijal se koristi za izradu ultrazvučnog senzora i priključenjem na napon, materijal se savija i proizvodi ultrazvučne valove koji se reflektiraju od objekt i vraćaju prema senzoru uzrokujući ponovno savijanje materijala i nastanak električnog impulsa. Širina primljenog električnog impulsa je proporcionalan udaljenosti objekta od senzora. U radu je korištena razvojna okolina eZ430-RF2500 na kojoj je implementiran mikrokontroler MSP430F2274. Za ostvarenje funkcionalnosti senzora izrađen je programski kod u Code Composer Studio okruženju kojim se programira mikrokontroler. Funkcionalnost senzora je ispitana brojnim mjerenjima. Utvrđen je raspon kuta i udaljenosti unutar kojih senzor uspješno određuje položaj objekta. Napravljen je eksperiment utvrđivanja objekta u 3D prostoru sustavom od više senzorskih čvorova. Konačno, napravljen je funkcionalni algoritam za određivanje položaja objekta u prostoru.
Abstract (english)
Ultrasound sensor is used for object position determination and it is based on ultrasound waves and their physical nature. The working principle of ultrasonic sensor is based on the piezoelectric effect. The piezoelectric effect is the appearance of an electric polarization in a material that strains under stress. Input voltage applied to such material causes it to flex and transmit ultrasonic waves and generates voltage when incoming ultrasonic waves flex it. Generated electric signal width is proportional to the object distance. This paper is based on the use of eZ430-RF2500 development tool which is implemented with microcontroller MSP430F2274. To accomplish full sensor functionality, a program code was implemented in Code Composer Studio environment. Sensor functionality was tested by experiments. Therefore, the range of angles and distances within which the sensor correctly determines the position of the object was established. An experiment was conducted determining object in 3D space by multiple sensor nodes. Finally, the algorithm is designed for functional position determination of the object in space.
