Sistema embarcado para controle da dosagem de sementes em taxa variável

Abstract

This work developed a platform to control rotary seed rate mechanisms at varying rates. Control is done through a mobile application for smartphones, which allows map files with planting areas and different dosage rates to be loaded and interpreted. Calculations for setting location, sowing rate and travel speed are performed on smartphones and the pulse rate is sent over wi-fi to the dosing disc rotation variation system. In this way, it was possible to control the speed of rotation of the dosing mechanisms, as a function of the variation of the machine-implement set displacement speed and the seed dosage for each management zone, which can be fixed or variable between different subdivisions of the machine. area. In the tests performed it was possible to verify that the system was able to determine the speed of travel, identify the zones and distribution rates and as a function of these determine the proper rotation of the dosing disc.
