Embodiment Construction

[0031] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0032] Please refer to figure 1 , shows a schematic structural diagram of a wind power generation system provided by an exemplary embodiment of the present application, and the wind power generation system includes a wind power generation device (ie, a fan) 120 and a fan blade detection device 140 .

[0033] The wind power plant 120 includes a wind turbine blade 122 and a tower 124 . The fan blades 122 are used to sweep the wind, so that the wind power generation equipment 120 converts wind energy into electrical energy, and stores the electrical energy in the energy storage equipment. The tower 124 is mainly used to support other equipment structures of the wind power generation equipment, for example, the fan blade 122 is conn...

Abstract

The invention discloses a fan blade detection method and device, a device and a storage medium, and relates to the field of application programs. The method comprises the steps that sound signals generated when fan blades sweep wind are collected through a sound collection device, spectrograms corresponding to the sound signals are generated, image recognition is carried out on the spectrograms through a damage recognition model, and damage recognition results of the fan blades are recognized from the spectrograms. According to the method, the accurate identification of the damage types of thefan blades based on the spectrograms is achieved, the manual inspection is not needed, the manpower resources are saved, and the health state of the fan blades can be monitored in real time.

Description

technical field [0001] The present application relates to the field of application programs, and in particular to a detection method, device, equipment and storage medium for fan blades. Background technique [0002] In response to the call of the World Environmental Organization, my country is committed to the development and use of clean energy, such as wind power generation with mature technology. [0003] Wind power generation depends on the fan, and the fan blade determines the wind capture capacity and efficiency of the fan. Therefore, the condition monitoring of the fan blade is of great significance. The traditional inspection method of fan blades is manual inspection, and the technicians regularly inspect the fan blades through human eye observation and hearing discrimination. [0004] The operation and maintenance cost of the above-mentioned manual inspection method for fan blades is high, and it is impossible to monitor the health status of the extension blades i...
