Offshore wind power pile foundation scouring real-time monitoring system and monitoring method
The invention discloses an offshore wind power pile foundation scouring real-time monitoring system and monitoring method. A data acquisition module, a fiber bragg grating acceleration sensor, a fiber bragg grating tilt angle sensor and a wind speed sensor of the monitoring system are installed on an offshore wind power pile. The method comprises the steps that soil parameters and pile foundation parameters are obtained and input into simulation software, wind power pile foundation response signals are output, and reference signals are selected; performing frequency domain and time domain analysis to obtain an inherent frequency-scouring depth table and a dip angle balance position-wind speed-scouring depth table; collecting pile foundation vibration acceleration data, inclination angle data and environment wind speed data; looking up a table to obtain first and second scouring depths; and error judgment is conducted, the scouring depth is determined, and continuous real-time monitoring of offshore wind power pile foundation scouring is completed. The device can continuously monitor the scouring condition of the offshore wind power pile foundation in real time, has the characteristics of high precision, high durability and real-time monitoring, and can effectively avoid accidents, thereby ensuring the safe operation of an offshore wind turbine generator.
本发明公开了一种海上风电桩基础冲刷实时监测系统及监测方法。监测系统的数据采集模块、光纤光栅加速度传感器、光纤光栅倾角传感器和风速传感器安装在海上风电桩上。方法包括：获取土参数和桩基础参数输入模拟软件中，输出风电桩基础响应信号，选取参考信号；进行频域和时域分析获得固有频率‑冲刷深度表和倾角平衡位置‑风速‑冲刷深度表；采集桩基础振动加速度数据、倾角数据和环境风速数据；查表获取第一和第二冲刷深度；进行误差判断，确定冲刷深度，完成海上风电桩基础冲刷的连续实时监测。本发明能够实时连续监测海上风电桩基础的冲刷情况，具有高精度、高耐久性和实时监测的特点，能够有效避免事故的发生，从而保证海上风电机组的安全运行。
