| Notes | For the extraction of wave frequency, a wave buoy that based on the ARM and Linux system is introduced. This system used SPSV210 which is a 32-bit controller as its control unit, expanding the acceleration sensor module, GPS and GPRS network transmission module.The acceleration is decomposed and calculated with the Hilbert algorithm,calculating the instantaneous frequency of wave. In order to acquire the attitude angle, we have to compute the integral of the angular acceleration which is through the Kalman filter. Finally, the necessary data is sent back to the monitoring center through the GPRS network. It is proved by practice that the system can effectively achieve the instantaneous frequency and ensure the stability and reliability of the data acquisition and transfer.
