Problems solved by technology

With the growth of time, the frictional aging of the rotating parts is easy to cause damage to the parts and affect the measurement of wind speed
In addition, the wind speed and direction detected on the moving platform are relative wind speed and direction, and the model is used to solve it. In addition, the measurement error needs to be combined with the attitude change of the hull. The solution model is often very complicated, and the timeliness of judgment is poor, and the wind direction data cannot be output in real time. , there are potential safety hazards in ship navigation

Abstract

The invention provides a measurement method and system for automatically correcting ocean wind speed and direction. The measurement method comprises the following steps: obtaining measurement data ofa ship to be measured; and constructing an Elman neural network model optimized based on a genetic simulated annealing algorithm, inputting the obtained measurement data of the ship to be measured into the trained Elman neural network model optimized based on the genetic simulated annealing algorithm, and outputting the corrected real wind speed and direction. An Elman neural network is optimizedby adopting a method of combining a genetic algorithm and a simulated annealing algorithm to acquire an Elman neural network model optimized based on a genetic simulated annealing algorithm; the corrected real wind speed and direction can be quickly and accurately output according to the model, errors are reduced, measured marine real wind data are more accurate, navigation control over the ship can be guided according to the marine real wind data, and the safety of the sailing ship is improved.

Description

Technical field [0001] The present disclosure relates to the technical field related to ocean wind speed and direction, and specifically, to a method and system for measuring ocean wind speed and direction that realize automatic correction. Background technique [0002] The statements in this section merely provide background information related to the present disclosure, and do not necessarily constitute prior art. [0003] The true ocean wind has important meteorological navigation significance for ships sailing at sea. If the true wind is not accurately measured, it will cause misjudgment to the navigator and affect the safety of the ship. Therefore, the study of wind plays an important role in the field of marine meteorology. The safety of ship navigation and marine development. True ocean wind cannot be directly measured on moving platforms such as ships. [0004] The inventor found that in the current wind speed measurement, the commonly used traditional mechanical anemometer...
