Embodiment 2

[0033] Such as figure 2 As shown, the present invention also provides a method for improving accuracy based on wave buoys, which specifically includes:

[0034] S1: During measurement, the acceleration data is measured by the acceleration sensor, and the water surface height h is obtained by calculating the second integral 0 , measure the pressure data P by the pressure sensor, and obtain the draft R=P / (1.025*9.8) of the floating body according to the pressure data;

[0035] S2: According to the buoy weight and external dimensions, the static draft R of the floating body is calculated by using the Archimedes principle 0 , according to the static draft R of the floating body 0 The corrected water surface height can be calculated, that is, the real water surface height h=h 0 +(R-R 0 );

[0036] S3: Calculate parameters such as wave height and period according to the corrected water surface height correction value h.

[0037] Among them, when using the above method, the fl...

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 a data storage and emission system, the floating body is connected with the anchoring system, and the anchoring system is fixed to the seabed; the acceleration sensor is fixed at the center of gravity in the floating body; the pressure sensor is fixed at the bottom of the floating body; the acceleration sensor and the pressure sensor are connected with the data acquisition and processing system; the power supply system, the data acquisition and processing system and the data storage and emission system are all fixed in the floating body; the power supply system, the data acquisition and processing system and the data storage and emission system are connected in pairs. Wave measurement errors caused by poor wave following performance of an existing floating body can be compensated, and the measurement precision of the wave buoy is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of marine engineering tests, in particular to a wave buoy combined with a pressure acceleration sensor and a method for improving its accuracy. Background technique [0002] In order to study the characteristics of wave elements in ocean engineering, the commonly used wave motion measurement methods mainly include manual visual observation, video monitoring and various wave buoys. Manual visual observation can be used to simply and roughly observe the height change of the wave surface, but this method is time-consuming and labor-intensive and the observation accuracy is lacking, so it is difficult to be widely used in experiments and engineering; Video is used for real-time observation and recording, and it is impossible to monitor the changes of waves in real time; wave buoys have the advantages of low cost and real-time measurement, and are often used for wave monitoring in marine environments and hydrauli...
