Claim 8:
9. The acoustic monitoring method for the health status of the offshore wind turbine and the ocean wave according to claim 8, wherein
a movement of the ocean wave on a sea surface where the wind turbine is located is observed;
hitting and breaking acoustic signals generated by the ocean wave at the tower and the sea surface after hitting the pile foundation are acquired;
an acoustic signal corresponding to a maximum load generated when a maximum ocean wave hits the pile foundation is selected as a second warning acoustic value;
a buoy-type acoustic emission apparatus is mounted at the sea surface; and
a load operational safety status of the pile foundation of the wind turbine is monitored based on the real-time acoustic signal and the second warning acoustic value.
