Title:

WAVE BUOY COMBINED WITH PRESSURE SENSOR AND ACCELERATION SENSOR, AND ACCURACY IMPROVEMENT METHOD

Document Type and Number:

WIPO Patent Application WO/2023/142392

Kind Code:

A1

Abstract:

Disclosed are a wave buoy combined with a pressure sensor and an acceleration sensor, and an accuracy improvement method. The wave buoy comprises: a floating body, an anchoring system, an acceleration sensor, a pressure sensor, a power supply system, a data acquisition and processing system, and data storage and transmission system; the floating body is connected to the anchoring system, and the anchoring system is fixed to the seabed; the acceleration sensor is fixed to the center of gravity inside the floating body; the pressure sensor is fixed at the bottom of the floating body; the acceleration sensor and the pressure sensor are connected to the data acquisition and processing system; the power supply system, the data acquisition and processing system, and the data storage and transmission system are all fixed inside the floating body; and every two of the power supply system, the data acquisition and processing system, and the data storage and transmission system are connected to each other. According to the present invention, a wave measurement error caused by poor wave-following performance of existing floating bodies can be compensated, and the measurement accuracy of the wave buoy is significantly improved.
