ANÁLISE DE UM PROTÓTIPO DE BAIXO CUSTO PARA AUXILIAR NA ATRACAÇÃO DE TRANSPORTES FLUVIAIS

This work presents the development of a low-cost prototype to assist in the docking of river transport, using an approximation sensor based on ultrasonic technology to measure the distance between the vessel and the mooring point in order to guarantee safety during anchoring. To solve this need, a functional prototype was built using an Arduino microcontroller as a central control unit, integrated with an HC-SR04 ultrasonic sensor to measure distances, and a 7-segment display to display the data collected in real time. The system allows the captain to have a clear reading of the remaining distance during anchoring, supporting the maneuver safely. Analyzes of the distances measured by the sensor were also carried out to evaluate the precision and functioning of the prototype. The results obtained demonstrated the viability of the proposed system, which uses low-cost electronic components to measure and display the distance between the vessel and the docking location. Its implementation offers an affordable alternative to assist in safe navigation in river transport, especially in riverside communities with limited resources. The study also contributed to discussing new applications of technology, aiming to improve water transport in the country.
