Uso de arduino e módulo GPS para monitoramento por telemetria de rotas de transportes por caminhões em minas a céu aberto

Abstract

Loading and transport operations account for the largest share of production costs in open pit mines. The main setbacks that corroborate these costs are related to the formation of lines of trucks, the allocation of incorrect routes for transportation, the inadequate sizing of the fleet and the idleness of loading equipment. In view of this, technological solutions have been sought through software that can assist in decision making and, thus, increase the efficiency of the process to reduce operating costs. The software responsible for vehicle routing in open pit mines is known as dispatch systems and has a high acquisition cost, which makes its use in small and

medium-sized mining enterprises unfeasible. In view of this, this work aimed to develop a low- cost and easy-to-implement solution for monitoring the transport routes by trucks in open pit

mines. To this end, prototypes of data transmission and reception were built using Arduino MEGA, GPS sensors and radio frequency transmitters / receivers, working together with software developed to store and manage the data received by telemetry. Due to the Coronavirus pandemic period, the idealized prototypes were not used in a real mine environment. However, the results were based on a telemetry transmission of simulated loading and transport activities in the UFC - Crateús Campus parking space. The simulation results attested to the simplicity of the acquisition and efficiency of the data processing and allowed to carry out the georeferenced monitoring of the trucks. The simulation allowed to prove the effectiveness of the system, leaving, therefore, the realization of practical tests in the small and medium-sized mining companies.
