Desenvolvimento de um sistema de baixo custo para correção de direcionamento em operações agrícolas – projeto informacional e conceitual

Abstract

Considering the existing problems with regard to quality in carrying out activities in the fields, the driving manual for agricultural machinery operations stands out, in which it stands out for being tiring for the operator and for not generating a homogeneous service. To overcome this problem, precision guidance systems are used, such as autopilot. However, these technologies are not accessible to all farmers, due to the fact that the added value for acquisition is considerably high. Thus, the objective of this work is to develop the specification and conceptual design of a low-cost targeting system for agricultural operations. The product project methodology was applied to the development, in which for this work, the focus was turned to the execution only of the planning and design macrophase (specification and conceptual design). As a result, in the planning macrophase, the scope of the project was elaborated, presenting the justification, objectives and retractions of the project. In the phase of the specification designed, the clients' needs were listed, in which they were evaluated, in order to generate the project specifications, in which values of goals and ways of evaluating them were fixed. Finally, in the conceptual design phase, the functional structure was built, which allowed the identification of the project's solution principles, ultimately generating the design of the targeting system that met the project specifications. The proposed concept proved to be theoretically efficient to meet project specifications and target cost.
