Estudo de Caso da Norma NR12 Demonstrada a Partir de uma Maleta Industrial

Abstract

Solutions for the industry require intelligent systems capable of communicating with each other and performing constant diagnostics, aiming for energy efficiency improvements and production gains. These robust projects seek process standardization and continuous monitoring, which are fundamental factors for the company's competitiveness strategy. Abrupt interruptions can lead to financial losses and a decline in production quality, caused by equipment malfunctions or emergency stops resulting from workplace accidents. To address these issues, NR12 - Regulatory Norm No. 12 was established to ensure workplace adequacy, minimize undesired interruptions, and provide greater worker safety. Considering the need for solutions that comply with NR12, this study proposes an initial analysis and presentation of an industrial automation kit compliant with the norm, as well as the design of a supervisory system for an Industrial Internet of Things (IIoT) monitoring platform, serving as a historian for data analysis and supervision. Based on the documentation available from the Ministry of Labor, a preliminary study of NR12 was conducted, correlating its requirements with the industrial kit. The industrial kit operated effectively, enabling the development of a supervisory system capable of monitoring motor speed, current, frequency, and voltage. The results demonstrate the importance of applying the concepts discussed for preventing and mitigating accidents involving machinery and equipment, in accordance with NR12.
