20.500.12556/DKUM-42310 SISTEM ZA KONTROLIRANO NANAŠANJE FITOFARMACEVTSKIH SREDSTEV NA CILJNE POVRŠINE V PROSTORU DREVES SADOVNJAKA System for the controlled application of pesticides on the target surface in the space of trees orchard V magistrskem delu smo razvili okolju prijazen avtomatiziran sistem, s katerim zagotavljamo kontrolirani nanos fitofarmacevtskega sredstva (FFS) na izbrane ciljne površine v prostoru habitusa dreves sadovnjaka. Realni model avtomatiziranega sistema smo realizirali s pomočjo prenosnega računalnika HP Compaq 6830s NA779ES, programskega orodja Matlab/Simulink R2011b, alternativne tehnike (mehko logično orodje FIS; Fuzzy Inference System), elektromagnetnih ventilov, krmilnega vezja elektromagnetnih ventilov, NI USB-6009 ADDA kartice, ultrazvočnih senzorjev, šob Lechler TR-80-015C in testnega poligona. Algoritem za pulzno širinsko krmiljenje elektromagnetnega ventila smo razvili s pomočjo orodja Matlab, pri čemer smo optimirali pravila in pripadnostne funkcije mehkega logičnega sistema. Rezultati so pokazali, da s pomočjo kontroliranega pulzno širinskega krmiljenja elektromagnetnih ventilov dosežemo enak učinek kot klasične metode, a ob manjši porabi FFS. In our work, we developed an environmentally friendly automated system, with which we can provide controlled application of pesticides on selected target areas in the habitus of the tree orchard. A real model of an automated system was realized by using a laptop HP Compaq 6830s NA779ES, software tool Matlab/Simulink R2011b, alternative techniques (fuzzy logical tool FIS; Fuzzy Inference System), solenoid valves, control-measuring electronic circuits, NI USB-6009 ADDA card, ultrasonic sensors, Lechler nozzles TR-80-015C and a testing polygon. We developed an algorithm based on pulse width modulation to control solenoid valve. We used Matlab tools, where we optimized the rules and membership functions fuzzy logic system. The results showed, that through a controlled pulse width modulated solenoid valves control, we can achieve the same effect as traditional methods, with lower consumption of pesticides.
