System and method for monitoring health state of offshore wind power wind turbine and sound waves of sea waves

An acoustic monitoring system for a health status of an offshore wind turbine and an ocean wave, the system comprising:

• a first laser transmitter;
• a second laser transmitter;
• a telephoto camera provided at a hub;
• a vibration detection sensor provided on a tower of a wind turbine;
• and
• four first acoustic detection sensors arranged at an interval of 90° along a circumference of the tower,
• wherein the first laser transmitter and the second laser transmitter are arranged at a bottom of a nacelle of the wind turbine and emit laser lights vertically downward;
• the first laser transmitter, the second laser transmitter, the telephoto camera, the vibration detection sensor, and the four first acoustic detection sensors are connected to a data acquisition and conversion module through a transmission module;
• a controller is connected to the data acquisition and conversion module and is configured to control operations of the first laser transmitter, the second laser transmitter, the telephoto camera, the vibration detection sensor, and the four first acoustic detection sensors;
• and a data display terminal is connected to the controller.
