Abstract
Kroz diplomski rad objašnjen je temeljni princip rada te je prikazano trenutno stanje tehnologije EMI senzora. Za razumijevanje temeljnog principa rada senzora objašnjeni su osnovni fizikalni zakoni elektromagnetske indukcije, samoindukcije, međuinduktiviteta i vrtložnih struja. Prikazana je usporedba najpoznatijih dostupnih EMI senzora koji se koriste u preciznoj poljoprivredi. Kao praktično rješenje napravljen je EMI senzor koji mjeri vodljivost tla. Napravljeni senzor obavlja zadanu funkciju detekcije slane vode, ali ima probleme zbog izravnog vezanja odašiljačke i prijemne zavojnice. Osmišljen je sustav koji pokušava smanjiti utjecaj navedenih smetnji korištenjem mehaničke i programske kalibracije. Mehanička kompenzacija koristi DABP strukturu, dok programska računa potrebnu kompenzaciju za svaki otipkani uzorak Kao zaključak diplomskog rada navedeni su dobiveni rezultati, uočeni problemi te moguća poboljšanja senzora.
Abstract (english)
The fundamental principle and the current state of the art of EMI sensors technology are explained and shown through this thesis. Basic physical laws of electromagnetic induction, self-induction, eddy current and mutual inductance are used to explain fundamental principle. The comparison of the most popular available EMI sensors used in precision agriculture is shown in overview. As a practical solution, EMI sensor for measuring soil conductivity has been designed. The designed sensor performs default function , but has major problems with direct mutual inductance link between transmitting and receiving coil. In order to reduce the impact of such disorder mechanical and software calibration has been used. Mechanical compensation use benefits of DABP structure, while software compensation calculate value of necessary compensation for each sample. As a conclusion of thesis are given the obtained results, observed problems and possible improvements of the EMI sensor.
