Implementação de uma plataforma didática de automação industrial utilizando Raspberry Pi com integração multiprotocolo e monitoramento

Abstract

This project aims to implement and validate a didactic industrial automation architecture based on the Raspberry Pi, with emphasis on multiprotocol integration applied to teaching courses such as Industrial Networks I, Industrial Informatics II, and Embedded Systems II. The solution is built around a Raspberry Pi 3 used as the central processing unit, responsible for driving an induction motor through a power interface and acquiring data from industrial sensors, including temperature via 1-Wire, temperature and humidity via I²C, and rotational speed obtained from an incremental encoder. The proposal focuses on a practical demonstration of the Raspberry Pi’s ability to operate simultaneously as a data acquisition node and as a server under different protocols, enabling communication between automation layers and supervisory applications through Modbus TCP, OPC UA, MQTT, and HTTP. Data and commands are made available for monitoring, control, and visualization in environments such as Node-RED and ScadaBR, including the development of dashboards and graphical interfaces to track process variables and actuator status. The expected outcome is a low-cost, secure, and flexible platform capable of supporting laboratory activities by integrating, within a single system, data acquisition, control, and multiprotocol communication. In this way, the work contributes to the practical training of students in automation and connectivity technologies associated with Industry 4.0, providing a replicable environment for demonstrations, testing, and validation of modern industrial architectures.
