摘要

Accelerometer buoys are used to monitor ocean-specific parameter wave heights. The accelerometer buoy uses a three-axis accelerometer, a gyroscope, a strong magnetic field meter and an electromagnetic compass module as the core circuit. Using the inertial navigation principle, the four-element method is used for coordinate conversion, and the low-pass filtering algorithm is used to process the acquired signal. The axial value can be obtained by quadratic integration of the signal value. The Z-direction displacement is used to calculate the wave height. At the same time, the inclination angle of the buoy and the horizontal plane at the upper zero point is calculated by the inclination measurement principle, and the electronic compass is used for correction to determine the wave direction method. The wave height measuring device is used to measure a series of waves and compared with the capacitance wave height sensor. The experimental results show that the vertical displacement curve is measured by the accelerometer buoy, which is consistent with the measured curve of the capacitive wave height sensor. The comparison of the measurement results shows that the error in the analysis method in the frequency domain is smaller. Therefore, wave observation devices based on gyroscopes and accelerometers meet the needs of wave experimental measurements.
