Abstract

Laboratorijski sustav za mjerenje i detekciju udaljenosti razvijen u ovom završnom radu sastoji se od induktivnog, magnetskog i ultrazvučnog senzora prisutnosti i razvojnog sustava STM32F429ZI DISCOVERY, čiji je programski kod izveden u razvojnom okruženju Keil µVision. Induktivni senzor IQ40-35NPS-KC0 i magnetski senzor MZ2Q–FTZPS–KP0 deklarirani su za detekciju prisutnosti objekta na udaljenostima od 35 mm, odnosno 50 mm. U ovom radu induktivnim senzorom je ostvarena detekcija željezne pločice na udaljenosti od 37 mm, aluminijske pločice na udaljenosti od 16 mm i bakrene pločice na udaljenosti od 29 mm, dok predmeti od drveta nisu detektirani. Magnetskim senzorom je uspješno detektiran položaj klipa unutar kućišta. Ultrazvučni senzor HC–SR04 koristi se za mjerenje udaljenosti objekta za razmake do 4 m. Tim senzorom je uspješno izmjerena udaljenost ravne aluminijske ploče od senzora do najviše 390 cm, objekta cilindričnog oblika do 200 cm, a obojene vrećice do 300 cm. Najveća točnost mjerenja udaljenosti od senzora postignuta je za ravnu aluminijsku ploču, a najmanja točnost za cilindrični objekt. Razvojni sustav STM32F429ZI DISCOVERY koristi se za prihvat i obradu podataka sa svih korištenih senzora te za prikaz izmjerenih vrijednosti u stvarnom vremenu na LCD-u. Laboratorijski sustav namijenjen je za upoznavanje s različitim vrstama senzora prisutnosti.

Abstract (english)

Laboratory system for proximity measurement and detection developed in this bachelor’s thesis consists of inductive, magnetic and ultrasonic sensors, STM32F429ZI DISCOVERY board and Keil µVision software. Inductive sensor IQ40–35NPS–KC0 and magnetic sensor MZ2Q–FTZPS–KP0 are declared for proximity detection of objects in the range of 35 mm and 50 mm, respectively. In this thesis an inductive sensor has successfully detected the iron board at 37 mm distance, the aluminum board at 16 mm distance and the copper board at 19 mm distance, while the wooden board was not detected. The magnetic sensor has successfully detected the position of a piston inside of a cylinder. Ultrasonic sensor HC-SR04 is used for measuring the distance of objects in the range of 4 m. This sensor has successfully measured the distance of the flat aluminum board up to 390 cm, the distance of the cylindrical object up to 200 cm and the distance of the colored bag up to 300 cm. The highest accuracy of the distance measurement from the sensor was achieved for a flat aluminum board, and the lowest accuracy for a cylindrical object. The STM32F429ZI DISCOVERY development board is used for receiving and processing data from all the sensors and for displaying measured value in real time on the LCD. This laboratory system is intended for familiarizing the user with the basic types of proximity sensors.
