The Kekan Ocean Wave Buoy is a small buoy measurement system that utilizes the principle of gravitational acceleration to measure waves. It can obtain real-time ocean environmental information such as wave height, wave period, wave direction, one-dimensional energy density spectrum, two-dimensional directional spectrum, and surface water temperature of waves. It has high measurement accuracy, small size, light weight, simple and convenient layout and maintenance, and is suitable for use in nearshore fixed point anchoring observation, onboard observation, and laboratory teaching. The wave sensor in this wave buoy uses imported motion sensors. There are three series of Kekan wave buoy standards, 0.5 meters, 0.4 meters, and 0.25 meters. 2、 Technical indicator (1) Wave height: measurement range (0m~30m), measurement accuracy (± (0.1+3%) × Measurement value) m); (2) Wave period: measurement range (2.0s~25s), measurement accuracy (± 0.25s); (3) Wave direction: measurement range (0 °~360 °), measurement accuracy (± 3 °); (4) Surface water temperature (optional): Measurement range (-2 ℃~35 ℃), measurement accuracy (± 0.2 ℃). 3、 Performance indicators (1) Size and weight: spherical, with a floating body diameter of 0.5m and a weight of approximately 35Kg; (2) Communication methods: Beidou satellite communication, Iridium satellite communication, and digital radio communication. (3) Observation interval: 1 measurement per hour, 1 measurement per 0.5 hour, continuous measurement; (4) Working time: It can run continuously for about 5-7 months with one measurement per hour. Using a disposable high-performance lithium battery pack for power supply, the battery pack can be easily replaced after running out of electricity. (5) Conventional wave characteristic parameters include: average wave height, average wave period, one-third wave height, one-third wave period, one-tenth wave height, one-tenth wave period, maximum wave height, maximum wave period, wave direction, and wave number. (6) Spectral characteristic parameters, including spectral significant wave height, spectral average period, spectral peak period, and spectral peak direction. (7) The buoy outputs real-time ocean wave spectrum information, including one-dimensional wave energy density spectrum and two-dimensional directional spectrum. There are 360 directional points with a direction interval of 1 °; The frequency interval is (0.5/64) Hz=0.0078125Hz, with a total of 64 frequency points, each with corresponding wave direction and wave direction expansion. (8) Store the sequence of sea surface changes in the SD card of the buoy. When using digital radio communication, it can output real-time sea level change sequences.
