Description

Technical Field

[0001] The embodiments of the present disclosure relate to the fields of building construction, wind power generation, and computer technology, and particularly to an abnormality monitoring system, method, and device for a wind turbine base support frame. Background Art

[0002] Wind power generation converts wind kinetic energy into mechanical energy, and then mechanical energy into electricity. Due to its cleanliness, environmental benefits, and flexible installed capacity, it has gradually become a major power generation method. Wind power generation primarily utilizes wind turbines ("wind turbines"), which consist of three main components: a rotor, a generator, and a tower. Because wind turbines are large, vertically mounted mechanical structures, the casting of the wind turbine base is crucial for its proper operation. Currently, when casting the wind turbine base, a wind turbine base support frame is typically used as the supporting structure for concrete pouring. The large amount of concrete poured can cause deformation and misalignment of the support frame, which can affect the quality of the wind turbine base casting.

[0003] Currently, monitoring support frame deformation and deflection is typically done manually, using instruments such as total stations. However, due to the large number of support rods (vertical and horizontal) included in the wind turbine base support frame and the concave structure of the wind turbine base, access is difficult, making it difficult to accurately monitor support frame deformation and deflection in a timely and effective manner.

[0004] The above information disclosed in this Background section is only for enhancement of understanding of the background of the inventive concept and therefore it may contain information that does not form the prior art that is already known to a person of ordinary skill in the art. Summary of the Invention

[0005] The content of this disclosure is used to briefly introduce concepts that will be described in detail in the detailed description section below.

[0009] On the third aspect, some embodiments of the present disclosure provide an abnormality monitoring device for a wind turbine base support frame, the device comprising: a determination unit, configured to respond to a rod deformation monitoring component corresponding to the supporting upright pole to detect that the supporting upright pole has undergone rod deformation, and determine the rod deformation amount corresponding to the supporting upright pole according to the rod deformation monitoring component corresponding to the supporting upright pole; a first control unit, configured to respond to the supporting upright pole being a main supporting upright pole, the rod deformation amount being greater than a first threshold value, and the rod deformation amount being less than or equal to a second threshold value, control a rotating camera to perform panoramic image acquisition on the supporting template group, and obtain a real-time image; a second control unit, configured to respond to the supporting upright pole being a secondary supporting upright pole, the rod deformation amount being greater than a third threshold value, and the rod deformation amount being less than or equal to a fourth threshold value, according to the supporting upright pole The pole position of the pole controls the rotating camera to collect images of the support template in the local area to obtain a real-time image; the generation unit is configured to generate support template status information based on the pre-trained support template positioning model and the above-mentioned real-time image; the first abnormality prompt unit is configured to characterize the support template abnormality in response to the support template status information, and send a support template abnormality prompt to the monitoring terminal; the second abnormality prompt unit is configured to send a main support pole abnormality prompt to the above-mentioned monitoring terminal in response to the support pole being the main support pole and the pole deformation variable being greater than the second threshold; the third abnormality prompt unit is configured to send a slave support pole abnormality prompt to the above-mentioned monitoring terminal in response to the support pole being the slave support pole and the pole deformation variable being greater than the fourth threshold.

[0010] In a fourth aspect, some embodiments of the present disclosure provide an electronic device comprising: one or more processors; a storage device on which one or more programs are stored, wherein when the one or more programs are executed by one or more processors, the one or more processors implement the abnormality monitoring system described in any implementation of the first aspect or the abnormality monitoring method described in any implementation of the second aspect.

[0012] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: through the abnormality monitoring system applied to the wind turbine base support frame of some embodiments of the present disclosure, timely and effective accurate monitoring of the deformation and offset of the support frame is achieved. Specifically, the reason for the inability to timely and effectively monitor the deformation and offset of the support frame is: manual measurement of deformation and offset through methods such as total stations. Since the wind turbine base support frame contains a large number of support rods, and the wind turbine base is a concave structure, it is inconvenient for personnel to enter, resulting in difficulty in timely and effective accurate monitoring of the deformation and offset of the support frame. Based on this, the abnormality monitoring system applied to the wind turbine base support frame of some embodiments of the present disclosure realizes timely and accurate monitoring of the deformation of the support uprights by designing a rod deformation monitoring component group. In practice, the support frame is mainly composed of support uprights, support cross bars and support templates. The support columns serve as the primary load-bearing structure. By installing a rod deformation monitoring assembly on each column, deformation monitoring can be effectively performed on this primary load-bearing structure. Compared to deformation monitoring of all support columns (both vertical and horizontal), this significantly reduces monitoring costs while ensuring effective monitoring. Furthermore, as the support formwork is in direct contact with the wind turbine base, displacement of the support formwork, especially before the concrete has set, can easily lead to concrete flow. Therefore, a rotating camera is used to capture images that include the support formwork. Furthermore, considering that deformation of the support columns, as the primary load-bearing structure, can cause displacement of the support formwork, the rod deformation is used as a trigger to control the timing of image acquisition by the rotating camera, thereby ensuring the robustness of the monitoring process. This anomaly monitoring system effectively and efficiently monitors the deformation and displacement of the support frame, thereby effectively ensuring the pouring quality of the wind turbine base.

[0030] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0034] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0035] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0036] First, refer to Figures 1 to 3 ,in, Figure 1 This is a cross-sectional diagram of the fan base. Figure 2 This is a perspective view of the fan base from a top-down perspective. Figure 3 It is a schematic diagram of the positional relationship among the pole deformation monitoring assembly group, the rotating camera and the main supporting pole.

[0037] Among them, the abnormality monitoring system includes: a supporting pole group, a supporting template group, a supporting crossbar group, a pole deformation monitoring component group and a rotating camera, among which the supporting pole group includes: a main supporting pole and a slave supporting pole group.

[0038] The main support pole 1 is vertically arranged at the center of the fan base 5. Specifically, the main support pole 1 is a vertically arranged support pole used for supporting. Figure 1 The fan base 5 shown contains a cavity with a cross section approximately in the shape of a Chinese character "品". Since the fan base 5 is relatively large, concrete can be poured in layers.

[0039] The slave support poles 2 in the slave support pole group are spaced at predetermined arc lengths and are evenly and vertically arranged on a circumference centered on the main support pole 1. Specifically, the slave support poles 2 are vertically arranged support poles. The difference between the slave support poles 2 and the main support poles 1 is that the main support pole 1 is located at the center of the wind turbine base 5, so the main support pole 1 can be connected to the slave support poles 2 via the support crossbar 3.

[0040] The support template 4 in the support template group is attached to the inner wall of the fan base. Specifically, the support template 4 is an arc-shaped support plate in the perspective view. The support template 4 is attached to the inner wall of the fan base 5 to prevent the concrete from flowing into the cavity with a “pin” shape during the concrete pouring process of the fan base 5, and to constrain the shape of the inner wall of the fan base 5.

[0041] The support crossbar 3 in the support crossbar group is horizontally fixed between the main support vertical rod 1 and the slave support vertical rod 2, and between the slave support vertical rod 2 and the support template 4. Specifically, as shown in Figure 2 , the support crossbar 3 is arranged between the main support vertical rod 1 and the slave support vertical rod 2, and between the slave support vertical rod 2 and the support template 4 in a radial manner with the main support vertical rod 1 as the center. In particular, the main support vertical rod 1 and the support crossbar 3, the slave support vertical rod 2 and the support crossbar 3, and the slave support vertical rod 2 and the support template 4 are all fixed by steel pipe fasteners.

[0042] The rod deformation monitoring assembly in the rod deformation monitoring assembly group is arranged on the support vertical rod in the support vertical rod group. The rod deformation monitoring assembly includes a first laser assembly and a second laser assembly group. The first laser assembly is arranged at the bottom of the support vertical rod, and the second laser assemblies in the second laser assembly group are arranged at equal intervals on the support vertical rod. The rod deformation monitoring assembly and the support vertical rod correspond one-to-one. The rotating camera 8 is arranged at the top of the main support vertical rod 1 and faces the support template 4. Specifically, as shown in Figure 3 , the first laser assembly 6 is arranged at the bottom of the main support vertical rod 1. The second laser assemblies 7 are arranged at equal intervals on the main support vertical rod 1. During the calibration stage of the rod deformation monitoring assembly, it is necessary to ensure that the laser emitted by the first laser assembly can pass through the second laser assembly. In addition, since the fan base 5 contains a cavity with a cross section approximately in the shape of “pin”, according to the pouring sequence, the tilt angle of the rotating camera 8 needs to be adjusted to ensure that the rotating camera 8 faces the support template 4 at different concrete pouring stages.

[0043] Secondly, referring to Figures 4 to 6 , wherein, Figure 4 is a top view of the first laser assembly in a closed state, Figure 5 is a top view of the first laser assembly in an open state, Figure 6 is a perspective view of the first laser assembly.

[0044] Optionally, the first laser assembly includes: a first annular fixed shell 9 and a laser ranging sensor group, the laser ranging sensor group includes a target number of laser ranging sensors 10, wherein the laser ranging sensors 10 in the laser ranging sensor group are evenly spaced and arranged on the first side of the first annular fixed shell 9. When the first laser assembly is fixed to the bottom of the supporting pole, the first side is the upper side of the first annular fixed shell 9. Figures 4 to 6 As shown, the first laser assembly includes eight laser ranging sensors 10. The first laser assembly has a ring-shaped structure when closed and a clamp-shaped structure when open and closed, allowing for easy attachment to the support pole and locking in place. Specifically, the first laser assembly is provided with a hinge, allowing for opening and closing around the hinge. Furthermore, a locking mechanism can be provided on the opening and closing portion to ensure a stable attachment to the support pole and prevent displacement when closed.

[0045] Next, see Figures 7 to 10 ,in, Figure 7 is a top view of the second annular fixed housing included in the second laser assembly, Figure 8 is a top view of the rotating ring included in the second laser assembly, Figure 9 is a bottom view of the rotating ring included in the second laser assembly, Figure 10 is a perspective view of the second laser assembly.

[0046] Optionally, the second laser assembly includes: a second annular fixed housing 11, a rotating ring 12, and a laser reflector assembly. The laser reflector assembly includes a target number of laser reflectors 13. The laser reflectors 13 in the laser reflector assembly are arranged on the second side of the rotating ring 12. The second annular fixed housing 11 and the rotating ring 12 are provided with a target number of light-transmitting holes 14 at equal intervals. A laser reflector 13 is provided between two adjacent light-transmitting holes 14 on the rotating ring 12. When the support pole is not deformed, the laser emitted by the laser ranging sensor 10 passes through the light-transmitting holes 14. When the second laser assembly is fixed to the support pole, the second side of the rotating ring 12 is the bottom side.

[0047] Specifically, since the second laser assembly includes a rotating ring 12, using a hinge-controlled opening and closing method like the first laser assembly will increase the structural complexity of the second laser assembly. Therefore, the second laser assembly uses a fixing bolt to control the second laser assembly to be locked in a suitable position on the support pole. The side of the second annular fixed shell 11 includes a through hole for passing the fixing bolt. The surface of the fixing bolt has an external thread, and the surface of the through hole has an internal thread. A rotating handle and a rubber fixing sheet are respectively provided at both ends of the fixing bolt. By providing a rotating handle, it is convenient for the user to apply force to twist the fixing bolt to rotate. By providing a rubber fixing sheet, the contact area between the fixing bolt and the support pole is increased, thereby increasing the stability of the fixation. During use, the second laser assembly can be inserted from the upper end of the support pole and locked by the fixing bolt.

[0048] Specifically, the rotation of the rotating ring 12 is controlled to control whether the laser passes through the light-transmitting hole 14 or is reflected by the laser reflector 13 .

[0049] Further, see Figure 11 and Figure 12 ,in, Figure 11 is a bottom view of the second annular fixed housing included in the second laser assembly, Figure 12 Schematic diagram of the positional relationship among the light-transmitting hole, the first reflection area, the second reflection area, and the third reflection area.

[0050] Optionally, a target number of reflective areas are provided on the second side of the second annular fixed housing 11. These reflective areas are annular regions centered around the light-transmitting aperture 14. When the second laser assembly is secured to the support pole, the second side of the second annular fixed housing 11 is the lower side. The reflective areas include a first reflective area 15, a second reflective area 16, and a third reflective area 17. Each of the first, second, and third reflective areas 15, 16, and 17 is annular and has the same width, centered around the light-transmitting aperture. The width can be represented by the difference in radius between the inner and outer circles of the first, second, and third reflective areas. The reflectivity corresponding to the first, second, and third reflective areas 15, 16, and 17 is different. By providing first, second, and third reflective regions 15, 16, and 17 with different reflectivities, when the support pole deforms, the laser beam no longer passes through the light-transmitting aperture but instead is irradiated and reflected by the reflective regions. Therefore, the laser beam's impact area can be determined based on the refractive index before and after reflection, as well as the reflectivities corresponding to the first, second, and third reflective regions 15, 16, and 17. Since the ring widths of the first, second, and third reflective regions 15, 16, and 17 are identical, the amount of support pole deformation can be determined. For example, the first, second, and third reflective regions 15, 16, and 17 can be coated with coatings of different reflectivities.

[0051] In addition, see Figure 13 ,in, Figure 13 This is the component architecture diagram of the rod deformation monitoring component.

[0052] Optionally, the first laser component also includes: a first power supply component, a first control component and a first wireless communication component, wherein the first power supply component is used to power the laser ranging sensor, the first control component and the first wireless communication component, and the first control component is used to control the laser ranging sensor and the first wireless communication component.

[0053] Specifically, the first control component can be a microcontroller constructed using a single-chip microcomputer. The first power supply component can include a battery and a corresponding battery control circuit. The first wireless communication component can use a low-power Bluetooth module. In particular, since the communication between the first wireless communication component and the second wireless communication component is mainly through the first wireless communication component sending a control signal to the laser component to control the rotation of the rotating ring, and the control signal for controlling the rotation of the rotating ring is a signal with low information volume and low transmission frequency, the use of a low-power Bluetooth module can not only meet the communication requirements, but also reduce power consumption as much as possible, thereby extending the working time of the first laser component.

[0054] Optionally, the second laser component also includes: a second power supply component, a micro motor, a second control component and a second wireless communication component, wherein the second power supply component is used to power the micro motor, the second control component and the second wireless communication component, the micro motor is used to drive the rotating ring to rotate, the second control component is used to control the micro motor and the second wireless communication component, and the first control component communicates wirelessly with the second control component through the first wireless communication component included.

[0055] Specifically, the second control component can be a microcontroller constructed using a single-chip microcomputer. The second power supply component can include a battery and a corresponding battery control circuit. The second wireless communication component can use a low-power Bluetooth module. In particular, since the communication between the second wireless communication component and the second wireless communication component is mainly through the second wireless communication component receiving the control signal sent by the laser component to control the rotation of the rotating ring, and the control signal for controlling the rotation of the rotating ring is a signal with low information content and low transmission frequency, the use of a low-power Bluetooth module can not only meet the communication requirements, but also reduce power consumption as much as possible, thereby extending the working time of the second laser component.

[0056] The above various embodiments of the present disclosure have the following beneficial effects: through the application of the abnormal monitoring system of the fan base support frame body of some embodiments of the present disclosure, timely and effective monitoring of the deformation and deviation of the support frame body is realized. Specifically, the reason why the deformation and deviation of the support frame body cannot be monitored in a timely and effective manner is that the deformation and deviation is measured manually by a total station. Since the fan base support frame body contains a large number of support rods, and the fan base is a concave structure, it is inconvenient for personnel to enter, which makes it difficult to monitor the deformation and deviation of the support frame body in a timely and effective manner. Based on this, the abnormal monitoring system of the fan base support frame body of some embodiments of the present disclosure realizes timely and accurate monitoring of the deformation of the support vertical rod by designing a rod deformation monitoring component group. In practice, the support frame body is mainly composed of support vertical rods, support horizontal rods and a support template. As the main force structure, the support vertical rod can effectively monitor the rod deformation of the main force structure by setting a rod deformation monitoring component on the support vertical rod. Compared with the method of monitoring the deformation of all support rods (support vertical rods and support horizontal rods), the monitoring cost is greatly reduced under the premise of ensuring the effectiveness of monitoring. In addition, the support template is a structure that directly contacts the fan base. When the support template is displaced, especially when the concrete has not solidified, it is easy to cause concrete to flow out. Therefore, a rotating camera is used to collect images containing the support template. Further, considering that the support vertical rod is the main force structure, when it deforms, it may cause the support template to displace, so the rod deformation of the support vertical rod is used as a trigger condition to control the timing of image collection by the rotating camera, thereby ensuring the robustness of the monitoring process. Through the above abnormal monitoring system, the deformation and displacement of the support frame body are accurately and effectively monitored, thereby effectively ensuring the pouring quality of the fan base.

[0057] With reference to Figure 14 , a flowchart 1400 of some embodiments of the abnormal monitoring method applied to the fan base support frame body according to the present disclosure is shown. The abnormal monitoring method applied to the fan base support frame body is applied to the above abnormal monitoring system and includes the following steps:

[0058] Step 1401, in response to the support vertical rod corresponding to the rod deformation monitoring component monitoring that the support vertical rod deforms, determining the rod deformation of the support vertical rod corresponding to the rod deformation monitoring component according to the support vertical rod.

[0059] In some embodiments, the subject (for example, a computing device) of the abnormal monitoring method applied to the fan base support frame body can determine the rod deformation of the support vertical rod corresponding to the rod deformation monitoring component according to the support vertical rod corresponding to the rod deformation monitoring component in response to the support vertical rod corresponding to the rod deformation monitoring component monitoring that the support vertical rod deforms.

[0060] As an example, the support pole group may include: a main support pole A and a slave support pole group. The slave support pole group may include: a slave support pole B, a slave support pole C, a slave support pole D, and a slave support pole E. Each support pole corresponds to a pole deformation monitoring component. Therefore, the main support pole A may correspond to the pole deformation monitoring component A, the slave support pole B may correspond to the pole deformation monitoring component B, the slave support pole C may correspond to the pole deformation monitoring component C, the slave support pole D may correspond to the pole deformation monitoring component D, and the slave support pole E may correspond to the pole deformation monitoring component E. Each support pole independently monitors whether the corresponding pole deformation occurs and the amount of pole deformation when the pole deformation occurs through the corresponding pole deformation monitoring component. Specifically, taking the main support pole A as an example, the pole deformation monitoring component A may include: a first laser component AA, a second laser component AB, a second laser component AC, a second laser component AD, and a second laser component AE. The second laser assembly AB, second laser assembly AC, second laser assembly AD, and second laser assembly AE can be arranged from bottom to top along the main support pole A. The light transmission holes included in the second laser assembly AE are closed (i.e., the corresponding light transmission holes are covered by the laser reflectors on the rotating ring of the second laser assembly AE). The light transmission holes included in the second laser assemblies AB, AC, and AD are all open. After the pole deformation monitoring assembly A is calibrated and the main support pole has not deformed, the laser light emitted by the first laser assembly AA should pass through the light transmission holes included in the second laser assemblies AB, AC, and AD, and be reflected by the laser reflectors included in the second laser assembly AE along the optical path back to the first laser assembly AA. At this time, the intensity of the reflected (laser beam) echo is stable and does not fluctuate significantly. When the main support pole A undergoes pole deformation, the number of the first laser assemblies through which the laser beam passes changes. At this time, the length of the optical path corresponding to the laser beam changes, which in turn causes the echo intensity to change. At this time, it can be considered that the main support pole A has been detected to have undergone pole deformation. The pole deformation monitoring of the remaining slave support poles is similar and will not be described here. In particular, the number of slave support poles can be increased according to the support strength requirements. The above example only shows 4 slave support poles to illustrate how the main support poles and slave support poles monitor pole deformation, as well as the pole deformation amount when pole deformation occurs, and does not limit the number of support poles, especially the number of slave support poles.

[0061] As another example, taking the main support pole A as an example, when pole deformation occurs, the laser beam cannot pass through a portion of the second laser assembly. In this case, for the second laser assembly that cannot pass through the laser beam, the laser echo intensity does not change before and after the corresponding rotating ring controls the closing and opening of the light transmission hole. The rotating ring included in the second laser assembly can be gradually controlled from bottom to top to control the closing and opening of the light transmission hole, thereby determining the location of the pole deformation. Furthermore, because the second side (lower side) of the second laser assembly is provided with a reflective area around the light transmission hole, when the laser beam falls into the reflective area and reflects back to the first laser assembly, the reflectivity can be determined based on the ratio of the laser power at the time of laser emission and the laser power of the laser beam after reflection. Since the reflectivity of the first, second, and third reflective areas is known, the reflective area where the laser beam falls can be determined and its distance from the light transmission hole can be determined, thereby calculating the pole deformation amount.

[0062] In particular, it should be noted that since the size of the reflection area is fixed, in order to ensure the effectiveness of solving the rod deformation variable in combination with the reflection area, it is necessary to appropriately increase the monitoring frequency of the rod deformation so that abnormalities can be detected in time when the supporting pole is deformed, while avoiding large deformation of the supporting pole, that is, when the laser beam falls outside the reflection area, the rod deformation variable cannot be estimated based on the reflectivity corresponding to the reflection area.

[0063] It should be noted that the above-mentioned computing device can be hardware or software. When the computing device is hardware, it can be implemented as a distributed cluster consisting of multiple servers or terminal devices, or it can be implemented as a single server or a single terminal device. When the computing device is embodied as software, it can be installed in the hardware devices listed above. It can be implemented as multiple software or software modules for providing distributed services, for example, or it can be implemented as a single software or software module. No specific limitation is made here. In particular, the above-mentioned computing device can also include a first control component included in the first laser component, a second control component included in the second laser component, and a corresponding camera control component included in the rotating camera.

[0064] In some optional implementations of some embodiments, the execution entity determines the pole deformation amount corresponding to the support pole according to the pole deformation monitoring component corresponding to the support pole, including:

[0065] Step S1: controlling the laser ranging sensor group included in the pole deformation monitoring assembly corresponding to the supporting pole to synchronously emit a laser beam group, and determining the average echo intensity corresponding to the laser beam group as the first echo intensity.

[0066] In practice, to prevent interference from affecting the distance measurement of a single laser ranging sensor, a laser ranging sensor group is used. This involves multiple laser ranging sensors emitting laser beams simultaneously. When the support pole is not deformed, the laser beam should pass through the light-transmitting apertures of each second laser assembly in the second laser assembly group and reflect back to the first laser assembly. At this point, the average of the echo intensities corresponding to each laser beam can be used as the first echo intensity.

[0067] Step S2: In response to the first echo intensity not being within the preset echo intensity range, the following processing steps are performed according to the second laser assembly group included in the pole deformation monitoring assembly corresponding to the support pole:

[0068] In practice, assuming the number and spacing of the second laser assemblies installed on the support pole are fixed and the support pole does not deform, the echo intensity corresponding to the laser light emitted by the first laser assembly should be within a stable echo intensity range. Therefore, determining whether the first echo intensity is within the preset echo intensity range can be used to determine whether the support pole has deformed. In particular, a data table of echo intensities and preset echo intensity ranges can be pre-calibrated for different numbers and spacings of second laser assemblies, thereby meeting the requirements for selecting the number and spacing of second laser assemblies in different scenarios and quickly determining pole deformation.

[0069] Step S21: taking out the second laser assembly at the target position from the second laser assembly group as the target laser assembly.

[0070] The target position is the position of the second laser assembly in the second laser assembly group that is closest to the first laser assembly.

[0071] As an example, continuing to refer to the example shown above for the main support pole A, the pole deformation monitoring component A corresponding to the main support pole A may include: a first laser component AA, a second laser component AB, a second laser component AC, a second laser component AD, and a second laser component AE. Among them, the second laser component AB, the second laser component AC, the second laser component AD, and the second laser component AE can be arranged from bottom to top along the main support pole A. In this case, the target laser component can be the second laser component AB. The reason for selecting the target laser component from the bottom to the top is that when a pole deformation occurs at a position in the main support pole A, the positions above this position may also be deformed. If the judgment is made from the top to the bottom, it is impossible to quickly and accurately locate the position where the pole deformation occurs.

[0072] Step S22: controlling the laser ranging sensor group included in the pole deformation monitoring assembly corresponding to the supporting pole to resynchronize and emit the laser beam group, and determining the average echo intensity corresponding to the laser beam group as the second echo intensity.

[0073] As an example, the laser beam group can be resynchronized by the laser ranging sensor group included in the first laser assembly AA corresponding to the main support pole A. In practice, by re-controlling the laser ranging sensor group to emit the laser beam group, the average echo intensity when the rotating ring of the target laser assembly is not blocking the light transmission hole can be obtained.

[0074] Step S23: controlling the rotating ring included in the target laser assembly to rotate so that the light-transmitting hole included in the target laser assembly is not light-transmitting.

[0075] As an example, the first laser assembly AA can send a control signal for controlling the rotation of the rotating ring to the target laser assembly (the second laser assembly AB) through the first wireless communication assembly included. When the target laser assembly receives the control signal for controlling the rotation of the rotating ring through the second wireless communication assembly included, the included rotating ring is controlled to rotate so that the light-transmitting hole included in the target laser assembly is not light-transmitting.

[0076] Step S24: In response to the rotation of the rotating ring being completed, the laser ranging sensor group included in the pole deformation monitoring assembly corresponding to the supporting pole is controlled to synchronously emit the laser beam group again, and the average echo intensity corresponding to the laser beam group is determined as the third echo intensity.

[0077] In practice, when the rod is deformed at the location of the target laser assembly, the laser beam no longer passes through the light-transmitting hole. At this time, whether the rotating ring blocks the light-transmitting hole or not, the echo intensity corresponding to the laser beam will not change. The reason is that the laser beam is irradiated within the reflection area. At this time, the reflectivity and the optical path length of the laser beam do not change. At this time, the echo intensity difference between the second echo intensity and the third echo intensity is less than or equal to the difference threshold.

[0078] Step S25: In response to the echo intensity difference between the second echo intensity and the third echo intensity being less than or equal to the difference threshold, the target reflectivity is determined according to the laser emission intensity corresponding to the laser beam group and the third echo intensity.

[0079] In practice, the target reflectivity can be calculated by taking the ratio of the laser emission intensity to the third echo intensity. Furthermore, since the rod deformation occurs at the target laser assembly location, the third echo intensity can be considered equivalent to the second echo intensity. Therefore, the target reflectivity can also be calculated by taking the ratio of the laser emission intensity to the second echo intensity.

[0080] Step S26: performing reflectivity matching on the target reflectivity with the reflectivity corresponding to the first reflective area, the reflectivity corresponding to the second reflective area, and the reflectivity corresponding to the third reflective area to determine the corresponding falling area.

[0081] In practice, the reflectivity difference between the target reflectivity and the (first, second, and third) reflective areas can be determined, and the reflective area corresponding to the minimum reflectivity difference can be used as the falling area.

[0082] In particular, it should be noted that since the area size of the reflection area is fixed, when determining the falling area in combination with the reflection area, only the situation where the laser beam falls within the reflection area is satisfied. Therefore, it is necessary to increase the monitoring frequency so that when the supporting pole undergoes a slight deformation (falls into the reflection area), the occurrence of the pole deformation can be promptly monitored by the pole deformation monitoring component.

[0083] Step S27: Determine the pole deformation amount corresponding to the supporting pole according to the falling area.

[0084] In practice, since the ring widths corresponding to the first, second and third reflection areas are the same, after determining the landing area corresponding to the laser beam, the ring width from the landing area to the light-transmitting hole can be used as the rod shape variable.

[0085] For example, when the laser beam falls on the first reflection area, the rod shape amount = ring width. When the laser beam falls on the second reflection area, the rod shape amount = 2 × ring width. When the laser beam falls on the third reflection area, the rod shape amount = 3 × ring width.

[0086] In practice, in order to increase the robustness of the rod deformation monitoring, the reflection area may be provided with more annular reflection areas in addition to the first reflection area, the second reflection area and the third reflection area.

[0087] Step S3: In response to the echo intensity difference between the second echo intensity and the third echo intensity being greater than the difference threshold, the second laser component group without the target laser component is used as the second laser component group, and the above processing steps are performed again.

[0088] In practice, when the target laser assembly is located without rod deformation, the laser beam passes through the light-transmitting aperture, which is shielded by the rotating ring. This causes the corresponding laser beam echo intensity to change. This is because the corresponding reflectivity and optical path length of the laser beam have both changed. At this point, the echo intensity difference between the second and third echo intensities exceeds the difference threshold. Therefore, the target laser assembly is located without rod deformation. Therefore, the above processing steps can be repeated, reselecting the target laser assembly to determine the location of rod deformation.

[0089] Step 1402 : In response to the supporting pole being the main supporting pole, the pole shape variable being greater than the first threshold and the pole shape variable being less than or equal to the second threshold, controlling the rotating camera to capture a panoramic image of the supporting template group to obtain a real-time image.

[0090] In some embodiments, the above-mentioned execution entity can control the rotating camera to capture panoramic images of the support template group in response to the support pole being the main support pole, the pole deformation variable being greater than the first threshold and the pole deformation variable being less than or equal to the second threshold, to obtain a real-time image.

[0091] In practice, since the main support poles are the core of the support frame, the remaining support poles and support formwork are directly or indirectly connected to the main support poles through support crossbars. Therefore, when the main support poles are deformed, the stability of the entire support frame may be affected. In this case, it is necessary to capture panoramic images as real-time images.

[0092] Step 1403, in response to the supporting pole being a slave supporting pole, the pole deformation variable being greater than the third threshold and the pole deformation variable being less than or equal to the fourth threshold, control the rotating camera to capture images of the supporting template in the local area according to the pole position of the supporting pole to obtain a real-time image.

[0093] In some embodiments, the above-mentioned execution entity can respond to the support pole being a slave support pole, the pole deformation variable being greater than a third threshold and the pole deformation variable being less than or equal to a fourth threshold, and control the rotating camera to capture images of the support template in the local area according to the pole position of the support pole to obtain a real-time image.

[0094] In practice, when a slave support rod deforms, the most direct effect is on the connected support formwork. Therefore, an image can be captured based on the support formwork connected to the deformed slave support rod as a real-time image.

[0095] In particular, since the slave support poles are evenly and vertically arranged on a circle centered on the above-mentioned main support pole with a preset arc length as the interval, when the number of slave support poles is fixed, each slave support pole corresponds to a fan-shaped area. Therefore, the fan-shaped area can be used as a local area to control the rotating camera to capture images of the support template contained in the local area as real-time images.

[0096] In addition, since the main support pole and the slave support pole are subjected to different forces, different thresholds are set, such as setting the first threshold and the second threshold for the main support pole, and setting the third threshold and the fourth threshold for the slave support pole, so as to judge the degree of deformation of different types of support poles, thereby controlling the image acquisition timing and acquisition method of the rotating camera.

[0097] Step 1404 : Generate support template status information based on the pre-trained support template positioning model and the real-time image.

[0098] In some embodiments, the execution entity may generate support template status information based on a pre-trained support template positioning model and real-time images. The support template positioning model may be a machine learning model used to locate and identify the position of the support template. The support template status information represents the position of the support template within the real-time image. For example, the support template positioning model may employ a Tiny-YOLO (You Only Look Once) model. This lightweight model is suitable for use cases requiring low computing power.

[0099] In some optional implementations of some embodiments, the execution entity generates support template state information based on a pre-trained support template positioning model and the real-time image, including:

[0100] Step S1: performing image noise reduction on the real-time image to obtain a noise-reduced image.

[0101] In practice, the real-time image can be subjected to image noise reduction by using a Gaussian filter to obtain a noise-reduced image.

[0102] Step S2: performing edge detection on the above denoised image to obtain an edge feature group.

[0103] In practice, because the rotating camera is positioned above the main support poles, the image will contain the support poles during rotational capture, which can obscure and segment the support template, hindering subsequent support template recognition. Therefore, the present disclosure can employ an edge detection algorithm, such as one based on the Canny operator, to perform edge detection on the denoised image and obtain a set of edge features. Specifically, the edge features can be composed of the position points contained within the edge.

[0104] Step S3: performing ray-type edge feature filtering on the edge feature group to obtain a ray-type edge feature group.

[0105] The extension lines corresponding to the ray-shaped edge features in the ray-shaped edge feature group converge at the same center point.

[0106] In practice, since the support frame is centered on the main support pole, the support poles and support cross bars are radially arranged. In this way, the edge features of the corresponding support cross bars can be filtered in combination with the radial characteristics of the support frame to form a ray-type edge feature group.

[0107] Specifically, first, the straight line equation corresponding to the edge feature can be fitted based on the position points included in the edge feature, and whether it is a ray-type feature can be determined based on whether it is compared with a point.

[0108] Step S4: determining the edge slope corresponding to each ray-type edge feature in the ray-type edge feature group.

[0109] In practice, the slope of the straight line equation corresponding to the ray-type feature can be used as the corresponding edge slope.

[0110] Step S5: Determine two ray-type edge features whose corresponding edge slopes meet the matching condition as a ray-type edge feature pair to obtain a ray-type edge feature pair group.

[0111] The matching condition is that the slope difference of the edge slopes corresponding to the ray-shaped edge features is less than a preset slope difference.

[0112] In practice, the supporting crossbar has a certain width. Therefore, during detection, one supporting crossbar corresponds to two edge features. Based on the radial characteristics, the ray-type edge feature pairs corresponding to the same edge crossbar can be further screened out according to the edge slope corresponding to the edge feature.

[0113] Step S6: For each ray-type edge feature pair in the ray-type edge feature pair group, perform local Gaussian blur on the area enclosed by the ray-type edge feature pair in the denoised image.

[0114] In practice, the area enclosed by the ray-shaped edge features is locally Gaussian blurred to weaken the segmentation and occlusion constraints of the support template caused by the support crossbar in the image.

[0115] Step S7: generating the support template state information according to the support template positioning model and the image after local Gaussian blurring.

[0116] In practice, the support positioning model can first use the Tiny-YOLO model to locate the position of the support template contained in the image after local Gaussian blurring to obtain the support template position information. The support template position information can include the positions of the four corner points of the support template in the image. Under normal conditions, any two adjacent support templates should correspond to the same interval. Therefore, the actual interval between two adjacent support templates can be obtained by determining the positions of the four corner points included in the support template position information corresponding to each pair of support templates. When the actual interval changes from the support template interval in the calibrated state, it indicates that the support template position is abnormal.

[0117] Step 1405 : In response to the supporting template status information indicating that the supporting template is abnormal, a supporting template abnormality prompt is sent to the monitoring terminal.

[0118] In some embodiments, the execution entity may send a support template abnormality prompt to the monitoring terminal in response to the support template status information indicating that the support template is abnormal.

[0119] In practice, the execution entity can send a support template abnormality notification to a monitoring terminal via a wireless connection. The monitoring terminal can be a remote control terminal. For example, the monitoring terminal can be a visual monitoring platform for wind turbine foundation construction.

[0120] Step 1406: In response to the supporting pole being the main supporting pole and the pole deformation being greater than the second threshold, a main supporting pole abnormality prompt is sent to the monitoring terminal.

[0121] In some embodiments, the execution entity may send a main support pole abnormality prompt to the monitoring terminal in response to the support pole being the main support pole and the pole deformation being greater than a second threshold.

[0122] Step 1407: In response to the supporting pole being a secondary supporting pole and the pole deformation amount being greater than a fourth threshold, a secondary supporting pole abnormality prompt is sent to the monitoring terminal.

[0123] In some embodiments, the execution entity may send a main support pole abnormality prompt to the monitoring terminal in response to the support pole being the main support pole and the pole deformation being greater than a second threshold.

[0124] The above-mentioned embodiments of the present disclosure have the following beneficial effects: through the abnormality monitoring method applied to the wind turbine base support frame of some embodiments of the present disclosure, the robust combination of the monitoring algorithm and the monitoring system is realized, thereby realizing accurate rod deformation monitoring and displacement monitoring of the support template.
