The invention discloses a pulse infrared thermal wave nondestructive testing device for coating defects of an offshore wind turbine generator, and relates to the technical field of offshore wind power detection. The system comprises a defect detection system, and a terminal of the defect detection system is connected with a flight system, a nondestructive detection system and a data feedback system. The flight system plans an offshore wind turbine generator coating defect detection route, automatically generates an optimal route and locates the position of an offshore wind power tower drum, the nondestructive detection system measures the position of the offshore wind power tower drum, and the offshore wind power tower drum coating defect is detected by controlling a thermal excitation method and measuring the temperature field change of the surface of the offshore wind power tower drum. The method comprises the following steps: acquiring crack, welding, corrosion and fatigue conditions of the surfaces of the offshore wind power tower drum and the blades, and performing data processing and image analysis on heat maps of the offshore wind power tower drum and the blades so as to judge types, positions and sizes of deep surface defects of the blades, so that defect detection of the offshore wind power tower drum and the blades is realized. And thus, the convenience of offshore wind power defect detection is effectively improved.
