Desenvolvimento de um sistema de aquisição de dados para monitoramento do desempenho de tratores agrícolas

Abstract

Knowing that the use of agricultural machinery directly affects production costs, alternatives are sought for the optimization of mechanized systems. The tractor forms the basis of agricultural mechanization, several factors affect the performance of agricultural tire tractors, among them, the added weights, the type of surface, the displacement speed and the type of tire selected. The main way to evaluate the traction of an agricultural tractor of tires is in the accomplishment of the test of the tractor in asphalted track or in the field. The objective of this work was the development of a data acquisition system to monitor the performance of agricultural tractors. The system developed consists of an acquisition central of signals sent from analog and digital sensors, which is responsible for processing and storing data. The parameters collected by the data acquisition system are the wheels slip, cinematic relationship between tractor axles, the displacement speed, the drawbar force and the fuel consumption. The data acquisition system developed using the ESP 32 platform can be used for agricultural tractor testing, since it presented adequate accuracy in the reading of the sensors signal, presenting robust data storage and easy man-machine interface.
