Ocean waves not only impact the marine environment but also determine the design safety of offshore wind power, oil and gas platforms, and port engineering projects. To acquire high-quality wave dynamics data, the Wave Spectrum Buoy has become an irreplaceable marine observation platform.
Our wave spectrum buoy, relying on nine-axis inertial navigation, intelligent attitude algorithms, and a low-power MCU architecture, can still output accurate and reliable wave spectrum data under complex sea conditions, making it a highly cost-effective professional wave spectrum monitoring system in the industry.
How the Wave Spectrum Buoy Works
The Wave Spectrum Buoy collects three-dimensional sea surface motion data through its built-in nine-axis IMU, including:
Acceleration
Angular velocity
Attitude angle
Vertical displacement
The data is then processed using advanced spectral analysis algorithms to calculate the frequency spectrum, directional spectrum, and energy spectrum.
Our technical team has made three major optimizations to the algorithm:
Displacement inversion algorithm to compensate for integral drift
Low-frequency energy stability enhancement
More accurate directional spectrum 3D reconstruction
Therefore, it has a significant advantage in swell observation.
What are our technological advantages compared to our competitors?
1. High stability even at low frequencies (0.04Hz)
This is the biggest weakness of traditional wave spectrometers. Our company has solved the low-frequency noise problem through algorithm optimization, making wave data more reliable.
2. More accurate three-dimensional displacement recovery
It can output precise displacement sequences in the east-west, south-north, and vertical directions, supporting high-precision calculation of the directional spectrum.
3. STM32 processor + ultra-low power system
It can perform efficient calculations while ensuring long-term battery life.
4. Lightweight floating body design, corrosion-resistant and wear-resistant
Suitable for long-term floating and highly resistant to wind and waves.
