Abstract

The invention discloses a marine wave height measuring system, which comprises a wireless communication module, a power module, a control board, a wireless communication antenna, a satellite positioning antenna and a casing. A six-axis sensor, a temperature sensor and a satellite positioning sensor are arranged on the control board. The six-axis sensor collects three-axis acceleration and three-axis angular acceleration data of a buoy; and the temperature sensor collects temperature data of the buoy and the control board carries out integration to obtain marine wave height data. In addition, the invention also proposes a wave height measurement algorithm. On the basis of a dynamic Kalman filter algorithm, a coordinate conversion algorithm and a Z-axis position algorithm, wave height data are obtained. The system has advantages of light weight, small size and high precision.

Description

technical field [0001] The invention relates to ocean data measurement technology, in particular to an ocean wave height measurement system and method. Background technique [0002] Sea waves are the main factors affecting the navigation of ships and the take-off and landing of amphibious aircraft. The swell and waves on the ocean are the energy movement caused by the influence of various factors in the seawater. This energy movement of water acts on the high-speed gliding ship or amphibious aircraft, which will cause an instantaneous increase in draft, increase in sliding resistance, and impact Increased g, poor splash performance, and destabilization of ships or amphibious aircraft. How to ensure the normal navigation of ships and the normal take-off and landing of amphibious aircraft requires the design of an ocean wave height measurement system. [0003] At present, the ocean wave height measurement system can be divided into non-buoy type and buoy type according to it...
