Proposição de redundância para validação de dados dos sistemas de despacho para equipamentos de infraestrutura de mina

Abstract

In a scenario of growing competitiveness in the mining market, companies are expected to have constant and predictable results, making it essential that they monitor the performance of their assets. Key Performance Indicators, known by their acronym KPIs, are used in the mining equipment fleet management as references to be achieves. The data that is monitored by different systems must be reliable to operational reality so that it can be used in analyzes involving performance measurements. Utilization is one of the main KPIs monitored. It is calculated through report of the dispatch system, made manually by the equipment operator and, therefore, its calculation is subject to errors. The present work aims to present a comparative method between the data from the dispatch system and the telemetry system of the mine infrastructure fleets, in order to establish an indicator of adherence between these data. The objectives are to allow the identification of inconsistencies and enable the handling of deviations, and increase the reliability of Utilization to, consequently, better represent the operational reality. Finally, two ways are proposed to calculate the adherence between dispatch data and telemetry data and the bulldozer was chosen to demonstrate, theoretically, how the calculation can be carried out.
