Desenvolvimento de um sistema de leitura e cálculo do rendimento para fitas transportadoras a granel

Abstract

Currently, it is not possible to measure manually and instantly, parameters such as angle of repose and product flow on a conveyor belt during its operation because of human delimitation. With the use of these parameters, the management of a grain storage company would be optimized, since the angle of repose, for example, implies in the sizing of warehouses where the product is stored. In addition, the reading of product flow on a conveyor belt assists in making important decisions such as the time required to transport a given volume of grain to its destination, or even, an estimation of the yield of cleaning and drying processes. Based on this, the present work focused on the implementation of a microcontrolled system of data collection in real time on conveyor, which was able to collect data of grain angle of repose and volume of product transported per unit of time on a conveyor belt developed for laboratory testing. The data obtained by the developed system show to be close to the actual values measured with a maximum absolute relative error of 8.17% in the measurement of total volume of product transported by the conveyor belt and maximum absolute relative error of 10.04% in the measurement of the product angle of repose average . The margin of error can be optimized with small improvements in the system, which indicates that it has the possibility of being implemented in commercial environments in order to meet its proposed objectives.
