Desenvolvimento de uma interface Homem-Máquina para acionamento e monitoramento de motores de indução trifásicos.

Abstract

Industrial automation has become one of the main focuses of technological development in recent years. This progress is driven by the increasing demand for productivity to meet society’s needs. In this context, certain factors are essential for optimizing efficiency, such as process automation with minimal human intervention and the ability to remotely control operations, reducing risks for operators. Based on these principles, the implementation of a Human-Machine Interface (HMI) through a smartphone application emerges as an efficient solution for operating equipment without direct exposure to hazards. This system enabled the activation of a three-phase electric motor and the monitoring of its current both during startup and in steady-state operation. Furthermore, it presents itself as a portable and wireless alternative, demonstrating great potential for industrial process monitoring. The integration between a smartphone and a microcontroller, communicating via the TCP/IP protocol, represents a practical application of Industry 4.0 concepts. In this regard, the use of educational tools such as MIT App Inventor proved highly effective for remote control. However, it could not entirely overcome the limitations imposed by the Ethernet Shield module. Nevertheless, through programming strategies, these restrictions were mitigated, making the system a promising tool for study and educational applications.
