Title: Ferramenta embarcada para auxílio à depuração e automação de testes em sistemas de IoT Abstract: The rapid growth of the Internet of Things (IoT) has driven the development of in- creasingly complex embedded systems, demanding solutions that simplify data analysis, validation, and debugging processes. In this context, this work proposes the development of an embedded system aimed at remote monitoring and test automation, serving as a support tool in the development cycle of connected devices. The system will be capable of recording, classifying, and transmitting asynchronous events generated by the firmware, enabling real-time or offline analysis through an integrated data logger. Communication with the external environment will be structured using the MQTT protocol, allowing the separation of acquired data into distinct topics such as diagnostic events, process vari- ables, and performance logs. The ESP-IDF framework will be employed, leveraging its connectivity libraries, MQTT protocol support, and file system management. The project aims to provide a flexible, low-cost, and easily adaptable platform to assist engineers and researchers in debugging and validating IoT oriented systems.

Title: 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.

Title: Análise da eficiência logística no transporte de madeira com pentatrens em uma fábrica de celulose com Simulação de Eventos Discretos Abstract: This course conclusion work aims to study, analyze, and implement improvements in the logistics process of a dry wood pulp factory, using the concepts of Discrete Event Simulation. The purpose of this study is to understand each stage of the process and analyze it both individually and as a whole, in order to identify possible bottlenecks and optimization points that may be preventing the process from reaching its full performance capacity. To ensure better understanding, some logistics concepts, Discrete Event Modeling, and the tools that can be used to simulate systems will be explained. In order to measure essential parameters for the analysis, factors such as travel time, cargo capacity, average distance traveled, number of daily trips, and others will be monitored and measured. In this context, the study aims to demonstrate the applicability of Discrete Event Simulation in everyday scenarios, through the resolution of a real case from the job market, highlighting the importance of this field of study and its correlation with Engineering.

Title: Ferramenta mmbarcada para diagnóstico e simulação de comunicação Modbus Abstract: This work presents the development of a portable and multifunctional embedded tool for Modbus RTU communication analysis, logging, and simulation, aimed at the maintenance and diagnostics of industrial networks in the field. Based on an STM32F407 microcontroller with a touchscreen graphical interface, the device operates in three modes selectable at runtime: master, slave, and sniffer/datalogger, with support for RS-232 and RS-485 interfaces. The firmware was structured around a custom Hardware Abstraction Layer (HAL) based on opaque pointers and dependency injection, easing maintenance and code portability. The results confirmed correct operation in all three modes, with reliable traffic capture and continuous frame logging to an SD card with timestamps. As a contribution, this work delivers a compact tool to support maintenance, diagnostics, testing, and educational activities related to Modbus RTU networks.
