Abstract
Description
Technical Field
[0001] This invention relates to the field of wave energy technology, specifically to an intelligent wave impact protection method and system based on artificial intelligence. Background Technology
[0002] In fields such as marine engineering, port facilities and ship equipment, the dynamic load of wave impact on the vibrating body and its base is an important factor leading to structural fatigue and damage. In the existing technology, the monitoring and protection system for wave impact usually uses a fixed sampling frequency to monitor the load pressure of the vibrating body, which is difficult to adapt to the dynamic characteristics of wave impact such as periodicity, nonlinearity and uneven energy distribution in real time.
[0003] Specifically, traditional methods have the following technical problems:
[0004] The sampling strategy is singular: the sampling method based on a fixed time interval cannot dynamically adjust the sampling frequency according to the energy characteristics of wave impact (such as high-frequency impact areas), which may lead to data loss in high-energy impact scenarios or resource waste in low-energy scenarios.
[0005] Incomplete feature extraction: It relies solely on the time-domain features of the vibrating body (such as vibration frequency), ignoring the influence of high-frequency energy distribution in the negative vibration waveform on the load pressure, making it difficult to accurately capture the instantaneous high-intensity load of wave impact;
[0006] Insufficient intelligent calibration capability: The lack of an adaptive calibration mechanism for the sampling frequency of pressure monitoring sensors makes it impossible to dynamically optimize the monitoring strategy by combining real-time load pressure and benchmark values, resulting in limited response accuracy and efficiency of the locking protection system.
