Problems solved by technology

[0004] Based on this, there are certain defects in the accuracy or applicability of the existing observation technology except gravity wave measurement, for example, optical wave measurement can only be measured in daytime, and acoustic wave measurement has large noise disturbance, etc.
However, the buoy gravity wave measurement technology can only measure the wave characteristics at a certain position, and the large-scale wave measurement needs to be arranged at multiple points, which is expensive and expensive

Embodiment 1

[0037] see Figure 1-10 , an omni-directional three-dimensional wave observation system at sea, which includes a shooting end for shooting, and the shooting end is fixedly installed on the edge of a structure on the sea through a fixed base 1; The control terminal is connected with the buoy terminal through wireless communication, and the buoy terminal is floating on the sea surface. The control terminal has the function of data processing and analysis, and compares and corrects the results of the shooting terminal and the buoy terminal. This system is an easy-to-install, reusable, high-precision, and large-scale omnidirectional three-dimensional wave observation system, which can realize multi-dimensional and omnidirectional measurements on and above water, and improve measurement accuracy through data integration and analysis through the control terminal.

[0038] Further, the shooting end includes a base 2 installed on the top of the fixed base 1, a loading motor 3 is inst...

Embodiment 2

[0046] The installation and use method of the omni-directional three-dimensional wave observation system at sea, first, according to the required observation range, determine the location of the shooting end and the buoy end, and arrange 2~3 buoys 19 within the observation range for calibration and correction of the shooting results;

[0047] The location of the control terminal should ensure that the solar panel 10 can receive good light, and ensure that the electric energy can be basically self-sufficient in daily work. If the weather conditions are not ideal, an external power supply can be used for power supply;

[0048] After the layout is completed, the control terminal controls the shooting frequency and the height rotation angle of the scanning camera, and collects the buoy observation results, compares the wave height and wave velocity at a certain position on the sea surface measured by the buoy with the shooting results at the corresponding position, and optimizes it,...

Abstract

The invention relates to a maritime all-dimensional three-dimensional wave observation system and an installation and use method, the maritime all-dimensional three-dimensional wave observation system comprises a shooting end used for shooting, and the shooting end is fixedly installed on the edge of a maritime structure through a fixing base; the shooting end is connected with a control end used for controlling the shooting process of the shooting end; the control end is in communication connection with the buoy end through wireless communication, and the buoy end floats on the sea surface. The system is composed of a shooting end, a control end and a buoy end, water surface and water multi-dimensional and all-directional measurement is achieved, data are integrated and analyzed through the control end, and the measurement precision is improved.

Description

technical field [0001] The invention relates to the field of marine engineering operation and maintenance, in particular to a marine omnidirectional three-dimensional wave observation system and an installation and use method. Background technique [0002] In recent years, the construction of my country's offshore and offshore projects such as cross-sea bridges, offshore wind power, and offshore oil and gas exploration has been in full swing. With the frequent occurrence of extreme weather in the world, marine disasters are becoming more and more severe, and the accompanying disastrous waves and solitary waves are intensifying threats to offshore structures. Therefore, it is necessary to develop a wave observation system for ocean engineering construction-intensive sea areas. [0003] At present, common wave observations are divided into three types: surface observation, near water surface observation, and underwater observation. Above water surface includes aerial photogra...
