Controlador embarcado de estacionamento de veículos baseado em FreeRTOS e Flutter

Abstract

This work presents the development of an embedded system for vehicle parking control, using the ESP32 microcontroller with the FreeRTOS real-time operating system, Firebase Realtime Database (RTDB) for backup, and communication via the MQTT protocol. The system monitors the occupancy and reservation status of parking spots through physical sensors and visual indicators, while controlling vehicle access through automated gates. User interaction is carried out via a cross-platform mobile application developed in Flutter, allowing real-time visualization of spot availability, reservation management, and gate control. The embedded logic ensures that any reserved or occupied spot is considered unavailable, with all state changes synchronized through MQTT publishing. The system architecture leverages FreeRTOS concurrent tasks distributed across the ESP32's cores, ensuring compliance with timing requirements. The conducted tests confirmed the functional, technical, and economic feasibility of the proposed solution.
