Prototipagem de semáforo de mina subterrânea em plataforma arduino

Abstract

Loading and transportation operations represent a large part of production costs in underground mines. Some of the factors that contribute to these costs are related to the traffic light system: when the operator needs to manually inform the system that it will travel through a certain section of the mine; to the number of passing bays and the places where they were built. In view of this, it is interesting to search for technological solutions through software that can assist in decision making and, thus, increase the efficiency of the process to reduce operational costs. Therefore, this work aims to develop a prototype using the Arduino Uno, low cost and easy to implement, to automate the traffic light system in one-way underground mines. To this end, planning was carried out using the tinkercad software, so that it was possible to infer in advance how the Arduino Uno would work in conjunction with the sensors. The selection of materials that were used to build the model was carried out to simulate vehicle traffic in one-way underground mines and to automate the traffic light system system. The experimental analyzes were validated in the execution of the prototype made on a pilot scale, so that it was functional, controlling traffic through the adopted traffic light circuit.
