A virtual instrument for automatic anemometer calibration with ANN based supervision

摘要

A fully automatic anemometer calibrator intended for performing fast and accurate calibrations has been developed to fulfill the increasing demand and strict requirements of the wind energy industry. Different sensors are connected to a computer where a virtual environment acquires and processes the incoming signals and controls a wind tunnel, allowing the calibration of the anemometer at the pre-selected air speed values. An important part of the resulting complex virtual environment is a supervising system, based on artificial neural networks and able to check and handle the possible malfunctions and deviations within the calibration process.
