The invention discloses a ship collision early warning method and system for an offshore wind turbine structure, and the method comprises the steps: carrying out the feature extraction of a ship historical acceleration signal collected by an acceleration sensor, and generating a ship collision database based on the time-frequency domain features corresponding to each ship type; the current acceleration signal acquired in real time is quickly identified and processed in combination with the ship collision database, so that the reliability of ship collision early warning can be effectively improved by using historical data, and the corresponding ship type can be quickly determined according to the ship collision database to improve the accuracy of ship collision early warning.
本申请公开了一种用于海上风机结构的船舶碰撞预警方法及系统,通过对由加速度传感器所采集到的船舶历史加速度信号进行特征提取处理,并基于与每种船舶类型对应的时频域特征生成船舶碰撞数据库,以结合该船舶碰撞数据库对实时采集到的当前加速度信号快速识别处理,不仅可利用历史数据来有效提高船舶碰撞预警的可靠性,还可根据该船舶碰撞数据库快速确定出相应的船舶类型,以提高船舶碰撞预警的准确性。
