High-precision sea wave characteristic analysis method

Abstract

The invention relates to a high-precision sea wave characteristic analysis method; a 9-SPS sensor is adopted for data acquisition, and the sensor is in contact with the sea waves, so that the acceleration of the sensor can represent the acceleration of a tested object. Nine piezoelectric ceramics are connected to the input ends of all channels of a charge amplifier through wires respectively, andsignals output by the charge amplifier are collected through a data acquisition card after impedance conversion and signal conditioning and amplification are carried out. In an industrial personal computer, matlab development software and a decoupling algorithm are utilized to design software, the deformation amount of the piezoelectric ceramics is calculated according to the amount of electric charges generated by the piezoelectric ceramics in the industrial personal computer, and finally the six-dimensional acceleration information of the tested object is obtained. After the acceleration information is obtained, further integral processing is carried out on the industrial personal computer, and the wave characteristics such as wave height, wave period and the like are calculated througha cross-zero method. A user can implement remote operation on the industrial personal computer through TeamViewer software on a PC.

Description

technical field [0001] The invention belongs to the technical field of ocean observation, and relates to a high-precision wave feature analysis method. Background technique [0002] Nowadays, with the development of the economy, the field of human activities has further expanded to the ocean, and oceanography has gradually become the object of attention. As one of the important research contents of oceanography, waves can effectively help people improve their control over ocean conditions. Wave height, wave direction, and wave period are important input parameters in the fields of ocean forecasting, disaster prevention and mitigation, ocean engineering, and navigation safety. The acceleration type wave buoy is a wave observation method with high accuracy. [0003] Currently, wave buoys mainly have the following problems. [0004] 1. Three uniaxial acceleration sensors are used, which will increase the measurement error due to the influence of the installation position; ...

Problems solved by technology

[0004] 1. Three uniaxial acceleration sensors are used, which will increase the measurement error due to the influence of the installation position;

[0005] Second, the integration effect of the hardware integration circuit on the strong random signal is not ideal, resulting in a large integration error;

[0006] 3. The research hotspots of wave processing are concentrated on the development of PC platform software, such as "A Wave Monitoring System and Its Working Method" with patent application number 201810860388.0, which is not as stable as industrial computer

[0007] Fourth, most products currently on the market cannot switch to remote operation, such as "A Wave Monitoring System" with patent application number 201821225254.3, which is not flexible enough
