Abstract:
The automation of industrial processes has become a necessity for the profitability and safety of work. These two factors need to go hand in hand to ensure customer confidence and competitiveness in the market. The control and automation of industrial systems and processes have existed for a few decades and are evolving more every day. The manual form of operation (the first form of control used by man) still present in many processes, presents the need for an operator who must know the system, have reasonable experience, skills and, as is known, many physical limitations. To automate these processes, it is necessary to use new technologies and field instruments that reproduce human senses, however, many times these instruments when installed do not undergo laboratory tests that represent the real operating scenario and when in contact with the aggressiveness of the process can present unexpected results (breakage, wear, oxidation) causing unscheduled stops in the production process. This work refers to the study carried out through the application of reliability methods and statistical analysis of stoppage events in the ore pile mapping radar systems at the Ponta da Madeira Maritime Terminal of the Vale company.
