Extraction of wave characteristic parameters based on MEMS sensor

摘要

Aiming at the problem that the wave frequency amplitude and other characteristic parameters need to be obtained in real time during wave power generation, a real-time remote wave characteristic parameter monitoring system is designed by using STM32F4 series high performance single chip microcomputer, MEMS motion sensor and GPRS wireless transmission technology. This paper focuses on the hardware structure of the monitoring terminal and the attitude integration of the MEMS motion data, and the extraction of the ocean wave characteristic parameters by the time-frequency domain analysis algorithm. The effectiveness of the method is verified by practical applications.
