Desenvolvimento de um sistema de medição de vibrações para uma torre de um aerogerador

Abstract

This work aims to development a vibration measurement system providing the measurements performed on a microSD memory card. This system is isolated from the electricity network. The system consists of a concerto microcontroller, an interface printed circuit board (PCB), two photovoltaic panels, two batteries, a charge controller and four ICP® accelerometers. The microcontroller is the brain of the acquisition system, responsible for processing the information and write to the external memory. The interface PCB is designed to connect the microcontroller to the accelerometers and the charge controller. The photovoltaic panels, the battery and the load controller are the generation and storage system, supplying energy for the system. In order to validate the developed system, tests were performed using vibrations of known frequency and intensity.
