Controlador e device drivers para seguidor solar de 2 eixos

摘要

In the last few years we have witnessed the growth in the awareness relativeto the effects of the climate change and global warming in the human life.The effects of extreme weather phenomenons are becoming more devastating.However we have also seen an increase in the consumer awareness relativelyto the sources of the energy that they use. There is also an increase inthe awareness from the power suppliers about the energy sources that theyprovide to their costumers. Nations that some years ago stood almost alonein defiance of the Kyoto protocol are now implementing programs that aimthe reduction of carbon dioxide emissions to the atmosphere, namely theUnited States of America.With this objective, the investment in cleaner energy sources has increasedconsiderably, both in research and in the creation of huge solar/eolian parkscapable of producing large amounts of energy. However the prohibitiveprices of the solar panels or of the solar trackers impedes the consumerof getting the return of the investment in a satisfactory time reducing theadherence to this kind of solutions. With this problem in our minds, theobjective of this master dissertation is to aim for a reduction in the associatedcost of the solar tracker solution by implementing new hardwareand software capable of performing satisfactorily while being cheaper thanthe commercial solutions available. This aims to ally the bigger efficiencyof the solar tracker solution (two axis) with a new control method free ofproprietary solutions that do not increase value, only burden the consumerand thus halting the adoption of this kind of technology.
