[0041] It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0042] Refer to Figure 1 , Figure 1 is a schematic structural diagram of a wind turbine tower base settlement analysis device for the hardware operating environment involved in the solution of the embodiment of this application.

Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0044] Those skilled in the art can understand that Figure 1 the structure shown in the figure does not constitute a limitation on the fan tower foundation settlement analysis device, and it may include more or fewer components than shown in the figure, or combine some components, or have different component arrangements.

[0045] As Figure 1 shown, the memory 1005, as a storage medium, may include an operating system, a network communication module, a user interface module, and a fan tower foundation settlement analysis program.

[0046] In Figure 1 the fan tower foundation settlement analysis device shown in the figure, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the fan tower foundation settlement analysis device of the present application may be arranged in the fan tower foundation settlement analysis device. The fan tower foundation settlement analysis device calls the fan tower foundation settlement analysis program stored in the memory 1005 through the processor 1001 and executes the fan tower foundation settlement analysis method provided in the embodiments of the present application.

[0047] The embodiments of the present application provide a fan tower foundation settlement analysis method. Referring to Figure 2 , Figure 2 which is a schematic flowchart of the first embodiment of the fan tower foundation settlement analysis method of the present application.

[0048] In this embodiment, the fan tower foundation settlement analysis method includes the following steps:

[0049] Step S10: Collect the image data of the target wind turbine tower foundation, and construct a three-dimensional model corresponding to the target wind turbine tower foundation according to the image data.

[0050] It should be noted that the execution subject of the method in this embodiment can be a terminal device with functions of model construction, data processing, and program running, such as a smart phone, a computer, etc., or an electronic device with the same or similar functions, such as the above-mentioned wind turbine tower foundation settlement analysis device. Hereinafter, the wind turbine tower foundation settlement analysis device will be taken as an example to illustrate this embodiment and the following embodiments.

[0051] It can be understood that the above-mentioned target wind turbine tower foundation is a basic structure used to support the wind turbine tower body in a wind farm. Its main function is to bear the weight of the wind turbine and various loads caused by wind force, and ensure the stability and safety of the wind turbine tower and its upper structure. Structurally, the target wind turbine tower foundation usually consists of a foundation bottom plate, columns, connecting components, etc. The foundation bottom plate is used to be in close contact with the foundation soil and transfer the load to the foundation; the columns are used to support the wind turbine tower body to ensure its verticality and stability; the connecting components are responsible for tightly connecting each part together to form an integral structure.

[0052] It should be understood that the above-mentioned image data can be the image data corresponding to the target wind turbine tower foundation at different angles, such as front image data, side image data, oblique image data, top-down image data, etc. This embodiment does not limit this.

[0053] In a specific implementation, the three-dimensional coordinates corresponding to the target wind turbine tower foundation in a three-dimensional space coordinate system can be determined according to the image data at different angles, and then a three-dimensional model corresponding to the target wind turbine tower foundation can be constructed according to these three-dimensional coordinates.

[0054] Step S20: Select several target points from the three-dimensional model, and perform settlement observation on the target wind turbine tower foundation according to the target points to obtain observation data.

[0055] It should be noted that the above-mentioned target points can be the preferred points for performing settlement observation on the target wind turbine tower foundation. In particular, the above-mentioned preferred points should be stable and reliable, not easily affected and damaged by external factors. The selection of the preferred points should avoid areas easily affected by environmental factors such as vibration and temperature changes, and at the same time should be convenient for measurement and observation to ensure the accuracy and reliability of the settlement data. Therefore, the observation points should be selected at the key parts of the wind turbine tower foundation, such as the four corners, the center point of the foundation, and the areas that may be affected by larger settlements.

[0056] It should be understood that the above-mentioned observation data can include the settlement amount, settlement time, settlement position, etc. corresponding to the target wind turbine tower foundation.

[0057] Step S30: Perform settlement analysis on the target wind turbine tower foundation based on the observed data to obtain the settlement trend corresponding to the target wind turbine tower foundation.

[0058] It should be understood that in actual use scenarios, the wind turbine tower foundation may be affected by various factors such as foundation soil quality, groundwater level changes, the weight of the wind power tower itself, wind loads, and earthquakes, resulting in a settlement trend of the wind turbine tower foundation. It can be seen that the emergence of the settlement trend is inevitable. The settlement trend can be divided into a normal trend and an abnormal trend. If the settlement trend corresponding to the target wind turbine tower foundation is a normal trend, it indicates that the working state of the target wind turbine tower foundation is normal at this time and can continue to be put into operation; if the settlement trend corresponding to the target wind turbine tower foundation is an abnormal trend, it indicates that the working state of the target wind turbine tower foundation is abnormal at this time and effective intervention needs to be carried out in a timely manner to avoid serious damage to the target wind turbine tower foundation.

[0059] In this embodiment, image data of the target wind turbine tower foundation is collected, and a three-dimensional model corresponding to the target wind turbine tower foundation is constructed based on the image data; several target points are selected from the three-dimensional model, and settlement observations are performed on the target wind turbine tower foundation according to the target points to obtain observed data; settlement analysis is performed on the target wind turbine tower foundation according to the observed data to obtain the settlement trend corresponding to the target wind turbine tower foundation. Compared with the traditional method for settlement analysis of wind turbine tower foundations, since the above method in this embodiment performs settlement observations on the target wind turbine tower foundation according to several target points selected from the three-dimensional model corresponding to the target wind turbine tower foundation, it is possible to accurately perform settlement analysis on the target wind turbine tower foundation according to the obtained observed data to obtain the settlement trend corresponding to the target wind turbine tower foundation, thereby realizing precise monitoring and timely warning of the settlement of the target wind turbine tower foundation.

[0060] Reference Figure 3 , Figure 3 is a schematic flowchart of the second embodiment of the method for settlement analysis of the wind turbine tower foundation in this application.

[0061] In a feasible implementation manner, the step S10 may include:

[0062] Step S101: Collect image data of the target wind turbine tower foundation, where the image data includes front image data, side image data, and oblique image data.

[0063] In specific implementation, the above-mentioned image data of the target wind turbine tower foundation can be collected by image acquisition devices such as high-resolution cameras, cameras carried by unmanned aerial vehicles, and three-dimensional laser scanners. Before collection, the collection environment can be cleaned and sorted out to avoid the influence of obstacles or reflective objects on the image quality, and at the same time ensure that the lighting conditions are appropriate to avoid blurred or distorted images caused by too strong or too weak light.

[0064] Step S102: Preprocess the image data, and extract features from the preprocessed image data to obtain key feature points.

[0065] It should be noted that the above key feature points may refer to corner points, edge points or points with significant texture changes in the preprocessed image data.

[0066] It can be understood that the steps for preprocessing the above image data may include operations such as denoising, enhancing contrast, and correcting distortion to ensure the clarity and accuracy of the image data, thereby providing a data basis for subsequent 3D model construction.

[0067] Step S103: Construct a 3D model corresponding to the target wind turbine tower base based on the key feature points and the image data.

[0068] In a specific implementation, 3D point cloud data can be generated based on the above key feature points and the above image data, and then the 3D point cloud data is converted into a 3D mesh model, thereby obtaining the 3D model corresponding to the above target wind turbine tower base.

[0069] In a feasible implementation manner, the step S103 may include:

[0070] Step S1031: Obtain the pose information of the camera corresponding to when the image data is collected, and generate a sparse point cloud according to the pose information and the key feature points.

[0071] Step S1032: Convert the sparse point cloud into a dense point cloud by a multi-view stereo vision method, and construct an initial model according to the dense point cloud.

[0072] It should be noted that the above sparse point cloud refers to point cloud data with a small number of points and a large distance between points, and the above dense point cloud refers to point cloud data with a large number of points and a small distance between points.

[0073] In a specific implementation, the depth maps of the target wind turbine tower base from different perspectives can be determined based on the above sparse point cloud, and then these depth maps are fused to obtain the above dense point cloud.

[0074] Step S1033: Remove noise and simplify the model for the initial model to obtain the 3D model corresponding to the target wind turbine tower base.

[0075] In this embodiment, image data of the target wind turbine tower foundation is collected. The image data includes front image data, side image data, and oblique image data. The image data is preprocessed, and key feature points are obtained by extracting features from the preprocessed image data. The pose information of the camera corresponding to the image data when it is collected is obtained, and a sparse point cloud is generated based on the pose information and the key feature points. The sparse point cloud is converted into a dense point cloud by a multi-view stereo vision method, and an initial model is constructed based on the dense point cloud. The initial model is subjected to noise removal and model simplification to obtain the three-dimensional model corresponding to the target wind turbine tower foundation. Compared with the traditional method for analyzing the settlement of wind turbine tower foundations, the above method in this embodiment constructs the three-dimensional model corresponding to the target wind turbine tower foundation according to the image data of the target wind turbine tower foundation and the key feature points in the image data. On the premise of ensuring the accuracy of the three-dimensional model, it avoids spending a large amount of manpower and material resources on on-site surveying and mapping and model construction of the target wind turbine tower foundation, thereby reducing the cost of model construction and improving the efficiency of model construction.

[0076] Reference Figure 4 , Figure 4 is a schematic flowchart of the third embodiment of the method for analyzing the settlement of the wind turbine tower foundation in this application.

[0077] In a feasible implementation manner, the step S20 may include:

[0078] Step S201: Determine the force conditions of each point in the target wind turbine tower foundation, and select several target points from the three-dimensional model according to the force conditions.

[0079] Step S202: Perform settlement observation on the target wind turbine tower foundation according to the target points to obtain observation data, where the observation data includes the settlement amount, settlement time, and settlement location corresponding to the target wind turbine tower foundation.

[0080] It should be noted that the above settlement amount refers to the vertical displacement of the target wind turbine tower foundation relative to its original position, and this displacement amount is usually used to measure the stability and safety of the wind turbine foundation. The normal range of wind turbine settlement varies depending on geological conditions, design standards, and wind turbine models. Generally, when designing, a maximum allowable settlement amount will be determined based on geological exploration results and engineering requirements. The maximum settlement amount is usually controlled within a few millimeters to the centimeter level to ensure the stability and safety of the wind turbine. The settlement time refers to the time when the settlement phenomenon occurs in the target wind turbine tower foundation, and the settlement location refers to the specific part where the settlement phenomenon occurs in the wind turbine tower foundation.

[0081] In specific implementation, tower foundation settlement sensors can be arranged at the above target points to perform settlement observation on the target wind turbine tower foundation, so as to obtain observation data.

[0082] In a feasible implementation manner, step S30 may include:

[0083] Step S301: Determine the settlement rate and settlement curvature corresponding to the target wind turbine tower foundation according to the observation data.

[0084] It should be understood that the settlement amount that occurs to the target wind turbine tower foundation within a preset time period can be determined according to the above observation data, and then the ratio of the settlement amount to the preset time period is used as the settlement rate corresponding to the above target wind turbine tower foundation; the settlement curve corresponding to the target wind turbine tower foundation can be fitted according to the above observation data, and then the settlement curvature corresponding to the target wind turbine tower foundation is determined according to the settlement curve.

[0085] Step S302: If the settlement rate is less than the first preset value and the settlement curvature is less than the second preset value, it is determined that the settlement trend corresponding to the target wind turbine tower foundation is a normal trend.

[0086] Step S303: If the settlement rate is greater than or equal to the first preset value or the settlement curvature is greater than or equal to the second preset value, it is determined that the settlement trend corresponding to the target wind turbine tower foundation is an abnormal trend.

[0087] It should be noted that the above first preset value can be flexibly set based on the actual scenario, and the default value is 0.02 mm / d; the above second preset value can also be flexibly set based on the actual scenario, and the default value is 0.2%.

[0088] In a feasible implementation manner, after step S30, it may further include:

[0089] Step S40: If the settlement trend is an abnormal trend, calculate the settlement difference value between each observation point in the target wind turbine tower foundation according to the observation data.

[0090] Step S50: Judge whether there is a risk of uneven settlement in the target wind turbine tower foundation according to the settlement difference value.

[0091] It should be understood that the settlement difference value between each observation point in the target wind turbine tower foundation can be compared with the average settlement value of each observation point. If the absolute value of the difference between the settlement difference value and the average settlement value accounts for a proportion of the average settlement value exceeding the preset proportion, it can be determined that there is a risk of uneven settlement in the target wind turbine tower foundation; if the absolute value of the difference between the settlement difference value and the average settlement value accounts for a proportion of the average settlement value not exceeding the preset proportion, it can be determined that there is no risk of uneven settlement in the target wind turbine tower foundation.

[0092] In this embodiment, the stress conditions of each point in the target wind turbine tower foundation are determined, and several target points are selected from the three-dimensional model according to the stress conditions; the target wind turbine tower foundation is subjected to settlement observation according to the target points to obtain observation data, where the observation data includes the settlement amount, settlement time, and settlement position corresponding to the target wind turbine tower foundation; the settlement rate and settlement curvature corresponding to the target wind turbine tower foundation are determined according to the observation data; if the settlement rate is less than the first preset value and the settlement curvature is less than the second preset value, it is determined that the settlement trend corresponding to the target wind turbine tower foundation is a normal trend; if the settlement rate is greater than or equal to the first preset value or the settlement curvature is greater than or equal to the second preset value, it is determined that the settlement trend corresponding to the target wind turbine tower foundation is an abnormal trend; if the settlement trend is an abnormal trend, the settlement difference value between each observation point in the target wind turbine tower foundation is calculated according to the observation data; whether there is a risk of uneven settlement of the target wind turbine tower foundation is judged according to the settlement difference value. Compared with the traditional wind turbine tower foundation settlement analysis method, the above method in this embodiment accurately determines whether the settlement trend corresponding to the target wind turbine tower foundation is a normal trend or an abnormal trend through the calculated settlement rate and settlement curvature corresponding to the target wind turbine tower foundation. At the same time, when the settlement trend is determined to be an abnormal trend, whether there is a risk of uneven settlement of the target wind turbine tower foundation is judged according to the settlement difference value between each observation point in the target wind turbine tower foundation, so that the maintenance personnel can intervene and take measures in time when there is a risk of uneven settlement of the target wind turbine tower foundation, and avoid serious damage to the target wind turbine tower foundation.

[0093] In addition, an embodiment of the present application also proposes a storage medium, on which a wind turbine tower foundation settlement analysis program is stored. When the wind turbine tower foundation settlement analysis program is executed by a processor, the steps of the wind turbine tower foundation settlement analysis method described above are implemented.
