The conception of a multiparameter equipament for evaluation of agricultural machinery cabins

Abstract

The functions of the cabin on agricultural machinery go beyond protecting against the risk of overturning and adverse weather conditions, such as wind and rain. The cabins must also have a shield against physical, chemical, and biological risks, present in crops. In this context, the work aims to present the design of equipment capable of measuring atmospheric pressure, the incidence of ultraviolet radiation from the sun, temperature, and relative humidity of the air, inside and outside agricultural cabins, at the same time. The design methodology used in the development of the equipment demanded the definition of customer requirements, which were converted into design requirements. From the analysis of these, the design specifications were established. To meet the formulated specifications, the functional structure of the equipment was defined through a synthesis process (operating concept). The conception generated by the equipment, in two modules, inside and outside the cabin, allows the performance of differential comparative analyzes between the parameters in the two environments considered, serving as a tool for the development of cabin designs for safer agricultural machines.
