—Wind blades are located high, cracks and other small faults are difficult to find.
—Energy farms are gradually expanding their production scale, and the requirements for production efficiency refinement are increasing
—Traditional wind turbine inspection is mainly for visual inspection, the form is divided into high-magnification binoculars, high-altitude around the descending visual inspection and maintenance platform inspection
—The above methods are different degrees of low inspection efficiency, high economic costs, fall from height safety risks and other problems.
