Technical Field
[0001] The present invention belongs to the technical field of wind power generation, and relates to a wind turbine tower internal detection system and method based on high-precision three-dimensional modeling. Background Art
[0002] In the wave of global energy structure transformation, wind power generation is gradually becoming an important part of the energy supply system with its clean and renewable characteristics. As the core equipment for converting wind energy into electrical energy, the efficient and stable operation of wind turbines is crucial to promoting the large-scale development and utilization of wind energy. In the entire wind turbine, the tower is a supporting structure, and its internal state is directly related to the overall safety and power generation efficiency of the wind turbine. Therefore, the inspection and maintenance of the internal condition of the tower is particularly important.
[0003] Traditional wind turbine tower internal inspection methods mainly rely on manual operation. This process usually requires maintenance personnel to enter the tower in person and conduct status assessment through visual observation and handheld measuring tools. However, this method has many limitations: first, manual inspection is inefficient and it is difficult to quickly complete a comprehensive inspection of the entire tower interior; second, the tower is tall and the internal environment is complex, which brings high safety risks to maintenance personnel; third, manual inspection is easily affected by subjective factors, and coupled with the limitations of inspection tools, it is often difficult to obtain detailed and accurate three-dimensional data inside the tower, which undoubtedly limits the in-depth analysis and scientific evaluation of the health status of the tower structure.
[0004] With the continuous advancement of wind power technology and the vigorous development of the wind power industry, the design of wind turbine towers has become more complex and the size has gradually increased, which has put forward higher requirements for detection work. Traditional detection methods are not enough when facing large and complex wind turbine towers. Not only are they inefficient, but they are also difficult to ensure the accuracy and comprehensiveness of the detection results, and it is difficult to meet the efficient and intelligent management needs of modern wind farms.

[0041] Embodiment 2: The present invention proposes a method for detecting the interior of a wind turbine tower based on high-precision three-dimensional modeling. Figure 2 As shown, the method includes the following steps: system initialization and self-checking, adaptive path planning, multimodal data acquisition, real-time data processing and SLAM (Simultaneous Localization and Mapping), multi-scale adaptive modeling, artificial intelligence-driven data analysis, mixed reality visualization and interaction, data management and transmission, and security monitoring and emergency response: S1. System initialization and self-test: The operator first transports the autonomous mobile detection device to the bottom of the wind turbine tower. After the system is started, it automatically performs a comprehensive self-test procedure, including but not limited to functional testing of each module, sensor calibration, communication link inspection, etc. The self-test results will be fed back to the operator in real time to ensure that the system is in the best working condition.
[0042] S2. Adaptive path planning: After the system self-check is completed, the adaptive path planning module starts working. This module first builds an initial environmental model through preset tower structure data and real-time environmental perception. Subsequently, an improved global path planning algorithm (such as a variant of the A* algorithm) is used to generate the initial path. During the detection process, the system dynamically adjusts the path based on the real-time collected data, uses local path planning algorithms (such as the dynamic window method) to avoid obstacles, and ensures 100% coverage while minimizing detection time.
[0043] S3. Multimodal data collection: During the inspection process, the system adopts an adaptive data acquisition strategy. This strategy dynamically adjusts the working parameters of each sensor according to the complexity of the environment and the inspection requirements. For example, a higher laser scanning density is used in high curvature areas (such as around welds and bolts), while the scanning density is appropriately reduced in flat areas. The sampling frequency of the panoramic camera and thermal imaging camera will also be adjusted as needed. Ultrasonic thickness measurement focuses on sampling at key structural locations. At the same time, the system evaluates data quality in real time and automatically performs additional collection when necessary.
[0044] S4. Real-time data processing and SLAM (Simultaneous Localization and Mapping): The collected multimodal data is first processed on the autonomous mobile detection device. This includes data preprocessing (such as denoising, downsampling), feature extraction, initial pose estimation and local map construction. The processed data is transmitted to the cloud server via a high-speed network for further optimization. Cloud processing includes global map optimization, loop detection, multi-sensor data fusion, etc. The system uses an improved graph optimization algorithm to improve the accuracy and robustness of SLAM.
[0045] S5. Multi-scale adaptive modeling: Based on the SLAM (Simultaneous Localization and Mapping) results, the system begins to build a 3D model of the tower interior. Figure 3 As shown in the figure, multi-resolution data structures (such as improved octrees) are used to store and process point cloud data. The system dynamically adjusts the model accuracy based on geometric complexity and semantic information, effectively controlling the amount of data while ensuring high-precision reconstruction of key structures. For complex areas, the system uses advanced surface reconstruction algorithms (such as improved Poisson reconstruction) and adaptive mesh subdivision technology to ensure the accuracy and detail retention of the model. At the same time, the system also performs texture mapping, fuses visible light and thermal imaging data, and provides richer surface information.
[0046] S6. AI-driven data analysis: Based on the construction of the 3D model, the system uses a series of artificial intelligence algorithms to conduct in-depth analysis, such as Figure 4 As shown, including: a) Defect detection: Use improved deep learning models (such as variants of PointNet++) to segment and classify point cloud data to identify potential defects such as cracks, corrosion, and deformation.
[0047] b) Deformation analysis: By comparing the current model with historical data, a high-precision deformation thermal map is generated. The system also uses a time series analysis algorithm to predict possible future deformation trends.
[0048] c) Stress distribution prediction: Combining finite element analysis and machine learning methods, the stress distribution of the tower structure is predicted based on the geometric model, material parameters and environmental data.
[0049] d) Life assessment: Taking into account the test results, historical data and environmental factors, the remaining life of key tower components is assessed.
[0050] S7. Mixed reality visualization and interaction: The system imports modeling and analysis results into mixed reality applications. Maintenance personnel can interact with 3D models through mixed reality devices (such as head-mounted displays). Functions include but are not limited to: a) Virtual Tour: A 1:1 scale virtual environment of the tower interior, supporting free navigation and zooming.
[0051] b) Multi-layer data visualization: can switch to display multiple layers of information such as geometric model, thermal imaging data, stress distribution, etc.
[0052] c) Real-time annotation: supports adding marks and annotations to the model and sharing it with other team members in real time.
[0053] d) Intelligent query: Quickly locate a specific area or retrieve relevant data through voice or gesture commands.
[0054] S8. Data Management and Transfer: The system adopts a hierarchical data management strategy: a) Edge storage: Short-term data caching on autonomous mobile detection devices to support offline working mode.
[0055] b) Cloud storage: Use a distributed file system to store raw data and use spatiotemporal indexing to optimize retrieval efficiency.
[0056] c) Intelligent compression: Differentiated compression strategies are adopted according to the importance of data to optimize storage space while ensuring key information.
[0057] d) Incremental update: Only the changed data is transmitted and stored, reducing network load and storage requirements.
[0058] S9. Safety monitoring and emergency response: During the entire detection process, the system continuously performs security monitoring: a) Real-time status monitoring: monitor key parameters such as position, posture, and power of the autonomous mobile detection device.
[0059] b) Environmental perception: Detect changes in the surrounding environment, such as abnormal temperature, gas concentration, etc.
[0060] c) Fault diagnosis: Use machine learning algorithms to analyze system operation data in real time and predict possible faults.
[0061] d) Emergency plan: According to different abnormal situations, the system can automatically start the corresponding emergency handling process, such as safe recovery, emergency braking, etc.
[0062] Through the combination of the above steps, the wind turbine tower internal detection method based on high-precision three-dimensional modeling of the present invention can efficiently, safely and accurately complete the tower internal detection task.
