Calculating method for main wave direction of wave direction buoy based on optimization classification and vector average

Abstract

The invention discloses a calculating method for the main wave direction of a wave direction buoy based on optimization classification and vector average, and belongs to the technical field of marinemonitoring. The calculating method comprises the steps that (1) data are pretreated; (2) aiming at each wave period, the instant wave directions of all sampling points in a range are calculated firstly, data of the instant wave directions of the sampling points are processed by classifying and vector average methods, and wave directions of single waves are obtained; (3) angle range division is carried out, the number of the wave directions of the single waves in each angle range is subjected to statistics and proportion count; and (4) a middle value of the angle range with the largest proportion count value is adopted as the main wave direction. The calculating method for the main wave direction of the wave direction buoy based on the optimization classification and vector average not onlyis effective in actual measurement, but also has high goodness fit with a manually observing result, the precision of the calculating method is better than the precision of a result of the main wavedirection measured in a traditional buoy algorithm, the stability and accuracy of measuring the main wave direction of the wave buoy are improved, and the calculating method for the main wave direction can be widely popularized and applied in marine observing equipment.

Description

technical field [0001] The invention belongs to the technical field of marine monitoring, and in particular relates to a method for calculating the main wave direction of a wave direction buoy based on optimal classification and vector averaging. Background technique [0002] In today's world, with the rapid development of science, economy and technology, the rapid increase of population, the shortage of terrestrial natural resources on the earth, the lack of energy and mineral resources has become one of the important problems that countries need to solve for sustainable development. Among them, the ocean, which is rich in reserves, has become one of the most researched scientific fields at present, and some considerable results have been obtained. Ocean energy includes tidal energy, wave energy, seawater temperature difference energy, ocean current energy and salinity difference energy. Therefore, the development and development of marine energy has become a strategic cho...

The method involved in the present invention is applicable to the wave direction buoy of the above-mentioned second type of working principle. The original bearing, heel and pitch data of the carrier measured by the sensor, the wave buoy will be subject to the randomness of the restoring moment, the Due to the randomness of the force factor, the buoy swing and the force asynchronous and other factors, the random error calculated by the traditional single wave direction measurement algorithm is relatively large
