The inexhaustible wind energy resources are receiving more and more attention and concern. The advancement and maturity of wind power generation technology has made offshore wind power an important direction for the development of wind power generation technology.

[0003] However, since offshore wind farms are generally built in intertidal zones or offshore waters, the construction cost is high, and the complex marine environment increases the difficulty of operating and maintaining offshore wind turbines. As a device for obtaining wind energy, the reliability of wind turbine blades directly affects the power generation quality and efficiency of offshore wind turbines. In addition, offshore wind turbine blades are larger and more expensive than onshore wind turbine blades. Accordingly, serious failures are more destructive and economic losses are also higher.

[0004] In order to reduce equipment failures and economic losses, offshore wind turbine blade noise collection and real-time monitoring are currently carried out through offshore wind turbine blade noise collection and application equipment; however, the current offshore wind turbine blade noise collection and application equipment has certain disadvantages.
