Description

technical field [0001] The invention relates to a monitoring system for an offshore wind power foundation. Background technique [0002] Offshore wind farms generally consist of multiple offshore wind turbines arrayed in the sea, and centralized power transmission through the offshore booster station platform. Offshore wind power is a highly technically complex field, and the complexity of the offshore wind power environment further increases its technical difficulty. In terms of its environment, the environmental impact factors of offshore wind power mainly refer to meteorological and hydrological conditions such as wind, waves, and currents. After the completion of the wind farm, due to the hydrodynamic effects of waves and currents, the single pile foundation of the wind turbine will be severely scoured locally, causing uneven settlement and inclination of the foundation, thereby affecting the stability of the wind turbine foundation. Therefore, it is necessary to monit...
