Ocean wave buoy based on six-dimensional acceleration sensor and wave statistic method

Abstract

The invention discloses an ocean wave buoy based on a parallel piezoelectric type six-dimensional acceleration sensor. The ocean wave buoy comprises a buoy body, a sensor system and a control system,wherein the control system arranged in the buoy body integrates wave acceleration information, wind speed information, wind direction information and azimuth angle information which is sent by an electronic compass, separately processes the characteristics of waves at the position of the ocean wave buoy body and meteorological data to calculate the main wave direction, the wave height, the wave period, the actual wind direction and the actual wind speed, and sends the calculated main wave direction, the wave height, the wave period, the actual wind direction and the actual wind speed to a monitoring system on a user side through a communication module. By means of the ocean wave buoy, the technical problems that ocean waves are observed can be solved, and the limitations in the prior art can be overcome; the wave characteristics, such as the wave height, the wave period and the wave direction, of the ocean waves and the meteorological factors, such as the wind speed and the wind direction, can be observed.

Description

technical field [0001] The invention relates to the fields of hydrology and marine technology, in particular to an ocean wave buoy based on a six-dimensional acceleration sensor and a wave statistical method. Background technique [0002] The observation and research of offshore waves plays a very important role in ocean development, transportation, national economic construction, national defense construction and maritime ship activities. At present, coastal areas are constantly suffering from various marine disasters, and offshore marine disasters have caused many people to suffer and huge economic losses. [0003] Representative ocean wave monitoring equipment at this stage includes SZF wave buoy, OSB-W4 wave buoy, SBF3-1 wave measuring buoy, etc. However, since the existing acceleration-type wave monitoring usually adopts the acceleration-displacement integration method of the hardware circuit, the integration effect of the wave acceleration signal with strong randomnes...

AI Technical Summary

Problems solved by technology

However, since the existing acceleration-type wave monitoring usually adopts the acceleration-displacement integration method of the hardware circuit, the integration effect of the wave acceleration signal with strong randomness is not ideal, and a large integration error will occur.

And the research focus is on the development of wave processing software on the PC platform, and the wave data processing system suitable for airborne embedded platforms has not yet been reported.

For the wave processing method of the PC-end platform, once the communication between the ocean wave monitoring equipment and the PC-end platform is disconnected, the data of the ocean wave monitoring equipment can only be temporarily stored, wait for the communication to resume, and then send to the PC end for further processing, which is inefficient and error prone

In addition, most ocean observation stations in my country already have the ability to forecast and monitor ocean waves, but ocean wave observation equipment mainly relies on foreign imports, which are not only expensive to import, but also inconvenient for after-sales and maintenance of imported ocean wave buoys. The process of localization of marine observation equipment is imperative
