The downtime cost of wind power industry is very high, if the failure can lead to generator downtime for several months, so in order to control the economic losses caused by downtime, the safety control requirements of equipment is also very strict, regular inspection and quality maintenance of wind power equipment has been a common thing to do in the industry;

As the core component, wind power generator has the characteristics of small size, light weight, complex and dense structure. The gearbox structure is complex, the manufacturing accuracy is very high, and the correlation degree with each component is also very close, such a complex structure is undoubtedly to bring unusually high difficulty to the quality inspection;

The traditional old testing method needs to disassemble the equipment bit by bit, and the equipment is also faced with a long time outage, which is not only time-consuming and laborious, but also has a certain impact on the economy, which is very impressive to the efficiency of the enterprise. Therefore, the gradual development of industrial endoscopes in recent years has brought a new detection means to the detection of wind power equipment, and gradually evolved into a mainstream detection tool;
