[0037] An AR coaching system for wind turbine hydraulic system, based on the wind turbine hydraulic system and electronic control 3D model, uses AI and AR to achieve intelligent perception and guidance of employees' operation process, and provides real-time information display of component functions, working principles, safety risks, and maintenance processes;

[0038] The AR coaching system also sets up a perception identification module for component coding, identifies equipment types through AI, and displays maintenance risk points and maintenance process information through AR;

[0039] In addition, the specific steps of AI are: first, collect images of hydraulic components through cameras to build a database, including samples under different angles and lighting conditions, and then use deep learning algorithms (such as convolutional neural networks) to train the collected images so that the model can recognize and classify different hydraulic components. Then, during the training process, the system captures the image in the current field of view in real time through the camera. The AI ​​algorithm extracts features from the captured image and matches them with the features in the database.

Once AI recognizes the component, the system extracts information related to the component from the database, such as maintenance risk points, operation steps, etc. Then, based on the recognition results, the AR system generates corresponding virtual information (text, icons, animations, etc.) and superimposes it on the user's field of view;

[0041] The perception and recognition module can display the maintenance risk points of the hydraulic station, including electric shock injury, chemical corrosion and hydraulic pressure injury, and provide corresponding maintenance process steps;

[0044] The training platform or AR coaching system is also scalable and supports the subsequent addition of other hydraulic circuits and training modules to meet diverse teaching needs and adapt to diverse teaching needs, and has good long-term use value.

[0045] In this embodiment, through AR technology, employees can intuitively see virtual information in actual operations, improve their understanding and memory, and the system provides real-time information on component functions, working principles, safety risks and maintenance processes to help employees quickly master the key points of operation. The image recognition capability of AI can automatically identify hydraulic components and provide specific operation guidance, which lowers the learning threshold. The perception and recognition module can display maintenance risk points in a timely manner to help employees take safety precautions before operation and reduce the accident rate. The digital twin technology combines theoretical knowledge with actual operations to enhance the practicality of learning and make theory easier to understand and apply. With the assistance of AI and AR, employees of this system can master complex maintenance processes more quickly and improve training efficiency.
