[0041] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0042] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0043] The present invention provides an AR-based remote service system and method for wind turbine spare parts, which solves the technical problems in the background technology.

[0044] like Figure 1 As shown, it is a main flow chart of a remote service method for using wind turbine spare parts based on AR provided by an embodiment of the present invention, and the remote service method for using wind turbine spare parts based on AR includes:

[0045] Step S10: after detecting that there is abnormal maximum value working information in one of the wind turbine towers, locating a first position where the abnormal maximum value working information is located;

[0046] Step S11: Scan the first position where the abnormal maximum value work information is located, generate real-time scanning model data, and display the real-time scanning model data on the AR device where the first user is located;

[0047] Step S12: receiving a scan modification input of the first position by the first user, and locating a second position where the abnormal maximum value work information is located, wherein the area where the second position is located is smaller than the area where the first position is located;

[0048] Step S13: Enhanced scanning and display of the area where the second position is located, and superimposed display of corresponding spare part image information.

[0049] AR technology uses computers to generate a realistic virtual environment with visual, auditory, force, touch and motion senses, and uses various sensor devices to "immerse" users in the environment, enabling direct and natural interaction between users and the environment. This technology uses computers to superimpose daily life environments and virtual objects into the same space, giving users an immersive feeling. It is more convenient to use than VR, easier to achieve the desired effect, and more easily accepted in daily life. Using AR technology, for example, attention is paid to the location of various components in the wind turbine, such as the location of the generator, variable pitch machine, main control system, etc. in the wind turbine tower.

[0050] When this embodiment is applied, after detecting that there is abnormal maximum working information in one of the wind turbine towers, the first position where the abnormal maximum working information is located is located, and the first position where the abnormal maximum working information is located in the wind turbine tower is located, so as to quickly find the location of the typical fault; the first position where the abnormal maximum working information is located is scanned to generate real-time scanning model data, and the real-time scanning model data is displayed on the AR device where the first user is located, and the first user's scan modification input for the first position is received, and the second position where the abnormal maximum working information is located is located, wherein the area where the second position is located is smaller than the area where the first position is located, and the second position where the abnormal sub-area is located is preliminarily located through the abnormal working information, and then the first position is reduced and refined, and the area where the second position is located is enhanced scanned and displayed, and the corresponding spare parts image information is superimposed and displayed, and compared based on virtual and real interaction, so as to facilitate the first user to intuitively judge the typical location of the fault, find a reference basis for other similar faults, quickly hit the real fault point, and improve the maintenance efficiency.

[0051] like Figure 2 As shown, as a preferred embodiment of the present invention, after detecting that abnormal maximum working information exists in one of the wind turbine towers, locating the first position where the abnormal maximum working information is located specifically includes:

[0052] Step S101: Detecting abnormal operation information in all wind turbine towers, wherein the abnormal operation information at least includes temperature information and noise information;

[0053] Step S102: when it is determined according to the abnormal operation information that at least one of the abnormal operation information is not within the normal operation information threshold range, it is determined that the wind tower is operating abnormally;

[0054] Step S103: locating the wind turbine tower where the abnormal maximum value working information in the abnormal working information is located, and locating the first position where the abnormal maximum value working information is located in the wind turbine tower.

[0055] When this embodiment is applied, temperature and noise anomalies are the main manifestations of abnormalities in the wind turbine tower. By locating the first position of the abnormal maximum working information in the wind turbine tower, the wind turbine tower where the abnormal maximum working information is located is used to facilitate rapid locating of typical faults.

[0056] As a preferred embodiment of the present invention, the normal working information threshold range is a working information range composed of the maximum values ​​in the historical working information range and the calibrated working information range, that is, the minimum value is taken from the smallest of the two, and the maximum value is taken from the largest of the two.

[0057] As a preferred embodiment of the present invention, scanning the first position where the abnormal maximum value work information is located, generating real-time scanning model data, and displaying the real-time scanning model data on the AR device where the first user is located specifically includes:

[0058] Step S111: after detecting that the first user is wearing the corresponding AR device, performing real-time scanning on the location where the abnormal maximum value work information is located;

[0059] Step S112: Displaying the real-time scanning model data generated by the real-time scanning in real time on the AR device where the first user is located.

[0060] When this embodiment is applied, it is detected that the first user is wearing the corresponding AR device, and then the position where the abnormal maximum value working information is located is scanned in real time. That is to say, the display is interrupted when the AR device is taken off, which reflects the characteristics of intelligence.

[0061] like Figure 3 As shown, as a preferred embodiment of the present invention, the receiving of the scan modification input of the first position by the first user, locating the second position where the abnormal maximum value work information is located, wherein the area where the second position is located is smaller than the area where the first position is located specifically includes:

[0062] Step S121: issuing operation prompt information, wherein the operation prompt information is used to represent the uniform rotation and movement of the scan model at the first position based on the scan operation input of the first user; since the rotation and movement are uniform, it is convenient to subsequently locate the time node at which the first abnormal working information suddenly changes; even if the input is not uniform, uniform changes can be achieved through input filtering and linear function conversion;

[0063] Step S122: detecting changes in first abnormal operation information during the uniform rotation and movement of the scanning model, wherein the first abnormal operation information is obtained through determination;

[0064] Step S123: When and only when the rate of change of the first abnormal working information with time first increases and then decreases or first decreases and then increases, locate the time node where the first abnormal working information suddenly changes, and trace the source and locate the second position based on the time node; it can be understood that when the rate of change of temperature or noise with time first increases and then decreases or first decreases and then increases, it means that the second-order derivative of temperature or noise with respect to time is not 0, that is, the change of temperature or noise with respect to time is manifested as alternating concave and convex changes in the corresponding image, and the alternating concave and convex changes indicate that there may be an abnormal working point, because if the workpiece breaks or deforms, it will cause uneven force on the surface of the workpiece, resulting in abnormal temperature conduction, etc. For noise, its essence is also a manifestation of energy. When the workpiece fails, its propagation will also be abnormal, such as at the surface position close to the workpiece.

[0065] When this embodiment is applied, in AR technology, the user operates by gazing with eyes or pointing with gestures, so that the three-dimensional object can interactively change its shape and appearance in the user's panoramic field of view according to the current task or need. Specifically, it is reflected in the uniform rotation and movement of the scanning model at the first position, so as to locate the time node where the first abnormal working information suddenly occurs, and trace the source and locate the second position based on the time node.

[0066] As a preferred embodiment of the present invention, the scanning operation input by the first user includes the first user operating by gazing with eyes or pointing with gestures.

[0067] It should be understood that virtual reality fusion display can expand the display screen to the real environment, so that computer windows and icons are superimposed on real objects, and then the user can operate them by gazing with the eyes or pointing with gestures.

[0068] As a preferred embodiment of the present invention, the step of obtaining the first abnormal operation information through determination includes:

[0069] Step S1221: obtaining the maximum ratio of abnormal working information exceeding the threshold range of normal working information;

[0070] Step S1222: determining the maximum value as the first abnormal operation information, and determining the value other than the maximum value in the abnormal operation information as the second abnormal operation information value.

[0071] When this embodiment is applied, the first abnormal working information and the second working information are distinguished here. On the one hand, it is convenient for the subsequent step-by-step finding of the abnormal sub-area. On the other hand, because under normal circumstances, the largest proportion of the normal working information threshold range is exceeded, it means that the abnormal information characteristics are more obvious. Therefore, the second position where the abnormal sub-area is located is preliminarily located through the first abnormal working information, which is also a reduction and refinement of the first position, so it is reasonable.

[0072] like Figure 4 As shown, as a preferred embodiment of the present invention, the enhanced scanning and display of the area where the second position is located, and the superimposed display of the corresponding spare part image information specifically include:

[0073] Step S131: when the second abnormal operation information is temperature information, a sub-region where the highest temperature is located in the region where the second position is located is detected, the sub-region is enlarged and displayed in the scanning model, and components in the sub-region are captured, and the sub-region is an abnormal sub-region;

[0074] Step S132: when the second abnormal working information is noise information, the radiation source direction of the highest noise sound wave in the area where the second position is located is detected, the radiation source direction is projected into a positioning sub-area in the scanning model, and the components in the sub-area are captured. The sub-area is an abnormal sub-area. The projected positioning sub-area means that when approaching the physical sub-area, since the propagation of sound will change with the propagation medium, the sub-area can be positioned according to the change of the propagation of sound;

[0075] Step S133: Identify the captured parts, and retrieve the corresponding spare parts images in the spare parts material information library according to the size and shape of the identified parts, and superimpose the spare parts images on the scan model according to the preset positioning points.

[0076] It can be understood that this embodiment is a further expansion of the aforementioned embodiment. After the second position of the first abnormal working information is captured, the sub-area is further located in combination with the highest temperature or the strongest noise in the second abnormal working information. Generally speaking, the highest temperature or the strongest noise is caused by a suitable component failure or abnormality. Therefore, by capturing the components in the sub-area, and then retrieving the corresponding spare parts image in the spare parts material information library according to the identified size and shape of the components, the spare parts image is superimposed on the scanning model according to the preset positioning point, and compared based on the virtual and real interaction, it is convenient for the first user to intuitively determine the real fault point.

[0077] like Figure 5 As shown, as another preferred embodiment of the present invention, on the other hand, a remote service system for wind turbine spare parts based on AR is provided, the system comprising:

[0078] The detection module 100 is used to locate a first position where the abnormal maximum working information is located after detecting that there is abnormal maximum working information in one of the wind turbine towers;

[0080] The precise positioning module 300 is used to receive a scan modification input of a first position by a first user, and locate a second position where the abnormal maximum value work information is located, wherein the area where the second position is located is smaller than the area where the first position is located;

[0081] The enhanced display module 400 is used to perform enhanced scanning and display on the area where the second position is located, and to overlay and display the corresponding spare part image information.
