Description

Technical Field

[0001] This disclosure relates to the field of wind power generation technology, and in particular to a comprehensive monitoring system and method for wind turbine generators. Background Technology

[0002] With the rapid development of the global marine economy, marine resource development, environmental protection, and the safety management of offshore facilities have become focal points. Currently, offshore wind power development has entered a stage of large-scale, commercial development, with its distribution widely covering nearshore and deep-sea areas. The large-scale deployment, height advantage, and stable power supply capabilities of wind turbine generators provide a natural foundation for building a distributed integrated monitoring network, thus gradually becoming an emerging platform for comprehensive monitoring of specific areas such as offshore.

[0003] However, due to the relatively singular function of wind turbine generators, which primarily focus on power generation efficiency, their comprehensive monitoring applications have not been fully explored. Therefore, how to achieve integrated "power generation and monitoring" based on wind turbine generators has become an urgent technical challenge to be solved. Summary of the Invention

[0004] In view of this, this disclosure provides a comprehensive monitoring system and method for wind turbine generators.

[0005] According to a first aspect of this disclosure, a comprehensive monitoring system for wind turbine generators is provided. The comprehensive monitoring system includes the following devices installed in the nacelle of the wind turbine generator: a top cover opening and closing device, a top lifting device, a first monitoring device, a bottom lifting device, a second monitoring device, an energy storage device, and a main control device. The first monitoring device is installed on the top lifting device, and the second monitoring device is installed on the bottom lifting device.

[0006] The energy storage device is used to power various parts of the integrated monitoring system with the electrical energy generated by the wind turbine's power generation system.

[0007] The main control device is used to control the top cover opening and closing device, the top lifting device, the bottom lifting device, the first monitoring device, and the second monitoring device to perform target monitoring of the wind farm area, and to receive and store the target data returned by the first monitoring device and the target data returned by the second monitoring device.

[0008] The top cover opening and closing device is used to drive the top cover of the wind turbine nacelle to open and close under the control of the main control device.

[0009] The top lifting device is used to move up and down under the control of the main control device so that the first monitoring device is located outside the top of the wind turbine nacelle or hidden inside the wind turbine nacelle.

[0010] The bottom lifting device is used to lift and move under the control of the main control device so that the monitoring device is located outside the wind turbine nacelle or stored inside the wind turbine nacelle.

[0011] The first monitoring device is used to acquire target data of the wind farm area under the control of the main control device and return it to the main control device;

[0012] The second monitoring device is used to acquire target data of the wind farm area under the control of the main control device and return it to the main control device.

[0013] In some embodiments of the first aspect of this disclosure, the wind turbine nacelle has a first compartment and a second compartment.

[0015] In some embodiments of the first aspect of this disclosure, the integrated monitoring system further includes: a self-organizing network device, which is used to realize communication connections between the top cover opening and closing device, the top lifting device, the bottom lifting device, the first monitoring device, the second monitoring device, and the main control device.

[0016] In some embodiments of the first aspect of this disclosure, the integrated monitoring system further includes: an underwater monitoring device and a circular track, the circular track being movably mounted on the wind turbine foundation, the underwater monitoring device being mounted on the circular track and capable of circumferential sliding along the circular track, the underwater monitoring device being used to identify and track underwater targets under the control of the main control device and return information about the underwater targets to the main control device.

[0017] In some embodiments of the first aspect of this disclosure, the integrated monitoring system further includes: an underwater control device disposed inside the wind turbine tower, the underwater control device being used to drive the underwater monitoring equipment to slide along the annular track and control the movement of the annular track.

[0018] According to a second aspect of this disclosure, a comprehensive monitoring method for wind turbine generators is provided, the comprehensive monitoring method being executed through the aforementioned comprehensive monitoring system; the method includes:

[0019] When comprehensive monitoring of wind turbine units is required, after the main control device detects that the wind turbine unit has stopped, it sends a top cover opening command to the top cover opening and closing device so that the top cover opening and closing device drives the second compartment top cover of the wind turbine unit to open.

[0020] A first movement command is sent to the top lifting device, which responds to the first movement command and lifts to a first predetermined position so that the first monitoring device is located outside the top of the wind turbine nacelle cover;

[0021] The main control device sends a second movement command to the bottom lifting device, and the bottom lifting device responds to the second movement command and descends to a second predetermined position so that the second monitoring device is located outside the wind turbine nacelle cover;

[0022] The main control device sends a start command to the first monitoring device and the second monitoring device. The first monitoring device and the second monitoring device respond to the start command and start automatically to perform target monitoring of the wind farm area.

[0023] The main control device receives and stores target data detected by the first monitoring device and target data detected by the second monitoring device.

[0024] In some embodiments of the second aspect of this disclosure, the method further includes: a main control device acquiring the target's azimuth from radar; the main control device determining the angle between the tail of the wind turbine nacelle and the target based on the target's azimuth; the main control device comparing the angle between the tail of the wind turbine nacelle and the target with a first preset angle threshold; if the angle between the tail of the wind turbine nacelle and the target is greater than the first preset angle threshold, controlling the wind turbine to yaw until the angle between the tail of the wind turbine nacelle and the target is less than or equal to the first preset angle threshold; if the angle between the tail of the wind turbine nacelle and the target is less than or equal to the first preset angle threshold, controlling a passive detection device to acquire the target's trajectory, controlling an optoelectronic device to track the target to acquire the target's video data, and controlling the fixed anti-drone device to perform identification and interference of drones in the wind farm area.

[0025] In some embodiments of the second aspect of this disclosure, the method further includes: sending an underwater monitoring command to an underwater control device; and the underwater control device activating an underwater sonar device according to the underwater monitoring command.

[0026] In some embodiments of the second aspect of this disclosure, the method further includes: an underwater control device acquiring the angle between an underwater sonar device and an underwater target; the underwater control device comparing the angle between the underwater sonar device and the underwater target with a second preset angle threshold; if the angle between the underwater sonar device and the underwater target is greater than the second preset angle threshold, then controlling the underwater sonar device to move along a circular track until the angle between the underwater sonar device and the underwater target is less than or equal to the second preset angle threshold; the underwater control device acquiring the height difference between the underwater sonar device and the underwater target; the underwater control device comparing the angle between the underwater sonar device and the underwater target with a second preset angle threshold; and the underwater control device comparing the angle between the underwater sonar device and the underwater target with a second preset angle threshold. The system is configured to consider the height difference between the underwater sonar device and the underwater target, and a preset height difference threshold. If the height difference between the underwater sonar device and the underwater target is greater than the preset height difference threshold, the system controls the circular track to move up and down along the wind turbine foundation until the height difference between the underwater sonar device and the underwater target is less than or equal to the preset height difference threshold. If the angle between the underwater sonar device and the underwater target is less than or equal to a second preset angle threshold, and the height difference between the underwater sonar device and the underwater target is less than or equal to the preset height difference threshold, the system controls the underwater sonar device to identify and track the underwater target to obtain data about the underwater target.

By integrating multiple types of monitoring equipment, it can monitor marine environmental anomalies in the wind farm area in real time, such as illegal vessels, pollution sources, and underwater obstacles. This achieves comprehensive and multi-angle real-time monitoring of the wind farm area, ensuring the safety of wind turbine units and their related marine facilities, improving the efficiency of marine resource management, and providing data support for marine environmental protection.

Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

Similarly, depending on the context, the phrases "if determination" or "if detection (of the stated condition or event)" can be interpreted as "when determination," "in response to determination," "when detection (of the stated condition or event)," or "in response to detection (of the stated condition or event)."

[0044] Figure 1 A schematic diagram of the structure and layout of the integrated monitoring system 100 is shown. (See also...) Figure 1 The integrated monitoring system 100 includes the following devices installed in the wind turbine nacelle 200: a top cover opening and closing device, a top lifting device 120, a first monitoring device, a bottom lifting device 130, a second monitoring device, an energy storage device 160, and a main control device 170.

[0045] See Figure 1 The top cover opening and closing device, the top lifting device 120, the bottom lifting device 130, the first monitoring device, and the second monitoring device are respectively connected to the main control device 110. The top cover opening and closing device, the top lifting device 120, the bottom lifting device 130, the first monitoring device, the second monitoring device, and the main control device 110 are respectively electrically connected to the energy storage device 160. The first monitoring device is installed on the top lifting device 120, and the second monitoring device is installed on the bottom lifting device 130.

[0046] Figure 2 A schematic diagram of the cabin structure of the integrated monitoring system 100 for wind turbine generators provided in this embodiment is shown. See also... Figure 2 The wind turbine nacelle 200 may include: a first compartment 210 and a second compartment 220. The first compartment 210 is used to house the power generation system of the wind turbine, and the second compartment 220 is used to house the top cover opening and closing device, the top lifting device 120, the first monitoring device, the bottom lifting device 130, the second monitoring device, the energy storage device 160 and the main control device 110 in the integrated monitoring system 100.

[0047] See Figure 2The first compartment 210 and the second compartment 220 are arranged in a front-to-back layout within the main structure of the wind turbine. The integrated monitoring compartment can be located at the rear of the nacelle, presenting an integrated appearance that is compatible with the existing wind turbine shape. Therefore, when there is no need for integrated monitoring, the wind turbine operates normally, and at this time, the wind turbine's appearance is no different from that of a conventional wind turbine, providing a certain degree of concealment.

[0048] See Figure 2 The top cover of the second compartment 220 is openable and closable. The top cover 221 of the second compartment 220 has an opening and closing function. Figure 3a The closed state of the second compartment roof 221 is shown. Figure 3b The open state of the second compartment roof 221 is shown.

[0049] The integrated monitoring system 100 can be supplied with a stable power source by wind turbine generators. The energy storage device 160 can utilize the electrical energy generated by the wind turbine generator system to power various components of the integrated monitoring system 100. This ensures the long-term stable operation of the integrated monitoring system 100 and improves its reliability. In specific applications, the energy storage device 160 can be an existing energy storage device within the wind turbine generator system or a stand-alone energy storage device within the integrated monitoring system 100.

[0050] Specifically, the energy storage device 160 can be used to supply power to the top cover opening and closing device, the top lifting device 120, the first monitoring device, the bottom lifting device 130, the second monitoring device, the main control device 110, the underwater control device 170 described below, the self-organizing network device 150, the underwater monitoring device, etc.

[0051] The top cover opening and closing device enables the automatic opening and closing of the top cover of the second compartment 220. Specifically, the top cover opening and closing device can be used to drive the opening and closing of the top cover of the wind turbine nacelle 200 (e.g., the second compartment 220) under the control of the main control device 110.

[0052] See Figure 2 The integrated monitoring system 100 may further include a self-organizing network device 150, which is used to realize communication connections between the top cover opening and closing device, the top lifting device 120, the bottom lifting device 130, the first monitoring device, the second monitoring device, and the main control device 110. In specific applications, the self-organizing network device 150 may be powered by an energy storage device 160 and installed on the top lifting device 120.

[0053] The self-organizing network device 150 can relay communication and transmit target data, status data, and control information from the first monitoring device. After monitoring devices such as radar 141, passive detection device 142, fixed anti-drone device 143, optoelectronic device 144, and underwater sonar device 145 acquire target data, they can centrally process the target data through the self-organizing network device 150 and transmit the target data to the main control device 110 as needed, thereby achieving target data storage.

[0054] During integrated monitoring, the wind turbine stops operating, and the rotor azimuth is adjusted to the positive Y position. After the top cover of the second compartment 220 is opened, the top lifting device 120 is raised to the first predetermined position so that the first monitoring device is located outside the top of the nacelle cover of the second compartment 220, and the bottom lifting device 130 is lowered to the second predetermined position so that the second monitoring device is located outside the nacelle cover of the second compartment 220.

[0055] Figures 4a-4c The diagram shows the positions of the top lifting device 120 and the bottom lifting device 130 during the execution of the monitoring task, that is, the structural diagram of the top lifting device 120 being raised to the first predetermined position and the bottom lifting device 130 being lowered to the second predetermined position. Figure 4a A top view of the top lifting device 120 platform is shown during the execution of the monitoring task. Figure 4b A side view is shown, showing the top lifting device 120 raised to a first predetermined position and the bottom lifting device 130 lowered to a second predetermined position. Figure 4c A cross-sectional view is shown of the top lifting device 120 raised to a first predetermined position and the bottom lifting device 130 lowered to a second predetermined position.

[0056] The top lifting device 120 can be used to lift and lower under the control of the main control device 110 so that the first monitoring device is located outside the top of the wind turbine nacelle 200 or hidden inside the wind turbine nacelle 200. The first monitoring device can be used to acquire target data of the wind farm area under the control of the main control device 110 and return it to the main control device 110. The first monitoring device may include, but is not limited to, radar 141, passive detection device 142, fixed anti-drone device 143, etc.

[0057] Radar 141 can be used to detect targets on the sea surface surrounding wind turbines, including but not limited to vessels illegally entering the wind farm area. This helps prevent unauthorized maintenance personnel from entering the wind turbine area and prevents collisions between vessels and wind turbine foundations.

[0058] The passive detection device 142 can be used to continuously track and locate targets to accurately pinpoint their movement trajectories. These targets include, but are not limited to, vessels illegally entering the wind farm area. For example, the passive detection device 142 can be used to acquire the movement trajectories of vessels illegally entering the wind farm area to prevent collisions between vessels and wind turbine foundations.

[0059] Fixed anti-drone devices can be used to detect, identify, and jam drones within a predetermined distance. For example, fixed anti-drone devices can be used to interfere with drones that illegally enter wind farm areas, preventing such drones from damaging wind turbine blades.

[0060] In this way, when there is a need for comprehensive monitoring, the wind turbine can be shut down, and the first monitoring equipment, such as the radar 141, passive detection equipment 142, and fixed anti-drone device, can be moved to the outside of the top of the second compartment 220 of the wind turbine through the top lifting device 120. This allows the wind turbine to take advantage of its height, thereby increasing the distance for comprehensive monitoring of water surface targets, improving early warning capabilities, and also increasing the range of drone interference.

[0061] Figure 2 In the example, the top lifting device 120 is equipped with a radar 141, a passive detection device 142, a fixed anti-drone device 143, and a self-organizing network device 150 (described below). These devices can change position via the top lifting device 120: located outside the top of the cabin canopy or hidden inside the cabin. When the first monitoring device is hidden inside the second compartment 220, the top cover of the second compartment 220 is simultaneously closed. When it is necessary to move the first monitoring device to the outside of the top of the cabin canopy of the second compartment 220, the top cover of the second compartment 220 is simultaneously open.

[0062] After the monitoring mission begins, the top cover opening and closing device, under the control of the main control unit 110, operates to open the top cover of the second compartment 220. During the monitoring mission, see... Figure 4a , Figure 4b and Figure 4c The top lifting device 120 is raised to a first predetermined position (e.g., at or near the top cover opening), causing the monitoring equipment mounted on the top lifting device 120 platform to be raised to the outer side of the top of the nacelle canopy of the second compartment 220. After the first monitoring equipment completes its monitoring task, see [link to relevant documentation]. Figure 2 Under the control of the main control device 110, the top lifting device 120 descends to its initial position (i.e., the default position when the integrated monitoring system 100 is not working) so that the first monitoring device installed on the top lifting device 120 platform is lowered into the cabin for concealment. Then, under the control of the main control device 110, the top cover opening and closing device operates the top cover of the second cabin 220 to close.

[0063] These devices are mounted on the platform of the top lifting device 120 and can be moved to the outside of the top of the naval canopy via the top lifting device 120. Specifically, depending on monitoring requirements, radar 141 can be positioned on the platform of the top lifting device 120 near the rear of the second compartment 220, fixed anti-drone equipment 143 and self-organizing network equipment 150 can be positioned on the platform of the top lifting device 120 near the front of the second compartment 220, and passive detection equipment 142 can be positioned on the platform of the top lifting device 120 near the rear of the second compartment 220. In practical applications, the specific deployment positions of radar 141, passive detection equipment 142, self-organizing network equipment 150, fixed anti-drone equipment 143, etc., can be flexibly adjusted as needed.

[0064] The bottom lifting device 130 can be used to lift and lower under the control of the main control device 110 so that the monitoring equipment is located outside the wind turbine nacelle 200 or stored inside the wind turbine nacelle 200; the second monitoring device can be used to acquire target data of the wind farm area under the control of the main control device 110 and return it to the main control device 110. The second monitoring device may include, but is not limited to, photoelectric equipment 144, etc.

[0065] The optoelectronic device 144 can be used to search for, detect, observe, and track targets using a visible light sensor in conjunction with an infrared thermal imager. For example, for vessels illegally entering a wind farm area, the optoelectronic device 144 can collect video data of these vessels, thereby enabling video recording for evidence collection.

[0066] The optoelectronic device 144 adopts a bottom lifting device 130, which concentrates the monitoring targets in the lower part of the cabin, provides a more direct bottom view, and eliminates the need for long-distance detection capabilities. It balances maintenance efficiency and space economy, supports ground operation, utilizes the redundant space at the bottom, has a low center of gravity and is wind resistant, has good dynamic stability, and has no electromagnetic compatibility issues.

[0067] See Figure 2 For example, the bottom lifting device 130 is equipped with a photoelectric device 144, which can be raised and lowered. The photoelectric device 144 utilizes the bottom lifting device 130 to switch positions: located outside the nacelle canopy or stored inside the nacelle. See also Figure 4b and Figure 4c During the monitoring task, the bottom lifting device 130, under the control of the main control device 110, descends to a second predetermined position (e.g., the outer side of the bottom of the second compartment 220), causing the photoelectric device 144 mounted on the bottom lifting device 130 to be moved to the outside of the nacelle of the second compartment 220. After the photoelectric device 144 completes the monitoring task, see... Figure 2Under the control of the main control device 110, the bottom lifting device 130 rises to the initial position (i.e., the default position when the integrated monitoring system 100 is not working), so that the photoelectric device 144 installed on the bottom lifting device 130 is moved back into the second compartment 220 and stored inside the cabin.

[0068] Figure 5 A schematic diagram showing the structure and layout of the underwater component of the integrated monitoring system 100 is shown. (See also...) Figure 6 The integrated monitoring system 100 also includes underwater monitoring equipment and a circular track 180. The circular track 180 is movably mounted on the wind turbine foundation. The underwater monitoring equipment (via, for example, a specific bracket) is mounted on the circular track 180 and can slide circumferentially along the track. By moving the circular track 180 up and down along the wind turbine foundation and by sliding the underwater monitoring equipment circumferentially on the track 180, it is possible to detect targets at different depths in the underwater environment surrounding the wind turbine.

[0069] Specifically, the underwater monitoring equipment may include, but is not limited to, underwater sonar equipment 145. Underwater sonar equipment 145 can be used to track and identify underwater targets such as small and medium-sized underwater fishing equipment to prevent such equipment from entering the wind farm area and avoid collisions between such equipment and wind turbine foundations.

[0070] See Figure 5 The integrated monitoring system 100 may further include an underwater control device 170, which may be installed inside the wind turbine tower and is communicatively connected to the main control device 110. The underwater control device 170 is connected to both the underwater monitoring equipment and the circular track 180, and can be used to drive the underwater monitoring equipment to slide along the circular track 180 and control the movement of the circular track 180, thereby achieving underwater target detection.

[0071] In this embodiment of the disclosure, the underwater sonar device 145 relies on the foundation of a wind turbine generator set to achieve comprehensive monitoring at different depths and in a 360-degree range, thereby improving the accuracy of underwater comprehensive monitoring.

[0072] The main control device 110 can be used to control the top cover opening and closing device, the top lifting device 120, the bottom lifting device 130, the first monitoring device, and the second monitoring device to perform target monitoring of the wind farm area, receive target data returned by the first monitoring device and the second monitoring device, and store them. In addition, the main control device 110 can also be used to control the underwater monitoring device and the circular track 180 to perform underwater target monitoring of the wind farm area through the underwater control device 170 described below, receive target data returned by the underwater monitoring device, and store them.

[0073] The main control device 110 may include a memory and a processor. The memory may store a computer program, and the processor can read and execute the computer program to control other parts of the integrated monitoring system 100 to implement the integrated monitoring method described below.

[0074] The main control device 110 may further include a communication component for communicating with the ad hoc network device 150 to acquire target data collected by the first monitoring device, the second monitoring device, and the underwater monitoring device. The memory in the main control device 110 may also be used to store this target data for later use.

[0075] Figure 6 A flowchart illustrating the integrated monitoring method for wind turbine generators provided in this disclosure is shown. See also... Figure 6 This integrated monitoring method may include the following steps:

[0076] Step 601: When comprehensive monitoring of the wind turbine is required, after the main control device detects that the wind turbine has stopped, it sends a top cover opening command to the top cover opening and closing device so that the top cover opening and closing device drives the second compartment top cover of the wind turbine to open.

[0077] Step 602: The main control device sends a first movement command to the top lifting device, and the top lifting device responds to the first movement command and lifts to a first predetermined position so that the first monitoring device is located on the outside of the top of the wind turbine nacelle cover;

[0078] Step 603: The main control device sends a second movement command to the bottom lifting device, and the bottom lifting device responds to the second movement command and descends to the second predetermined position so that the second monitoring device is located outside the wind turbine nacelle cover;

[0079] Step 604: The main control device sends a start command to the first monitoring device and the second monitoring device. The first monitoring device and the second monitoring device respond to the start command and start automatically to perform target monitoring of the wind farm area.

[0080] Step 605: The main control device receives and stores the target data detected by the first monitoring device and the target data from the second monitoring device.

[0081] Furthermore, this integrated monitoring method may include: the main control device acquiring the target's azimuth from radar; the main control device determining the angle between the tail of the wind turbine nacelle and the target based on the target's azimuth; the main control device comparing the angle between the tail of the wind turbine nacelle and the target with a first preset angle threshold; if the angle between the tail of the wind turbine nacelle and the target is greater than the first preset angle threshold, the main control device controls the wind turbine to yaw until the angle between the tail of the wind turbine nacelle and the target is less than or equal to the first preset angle threshold; if the angle between the tail of the wind turbine nacelle and the target is less than or equal to the first preset angle threshold, the main control device controls passive detection equipment to acquire the target's trajectory, controls optoelectronic equipment to track the target to acquire the target's video data, and controls fixed anti-drone equipment to perform drone identification and interference in the wind farm area. Thus, the wind turbine's yaw can be adjusted in real time using target data transmitted from radar to ensure the target falls within the monitoring range of passive detection equipment, optoelectronic equipment, and other monitoring devices, thereby enabling these devices to capture target data more accurately.

[0082] Furthermore, the aforementioned integrated monitoring method may also include: after the main control device detects that the wind turbine has stopped, it sends an underwater monitoring command to the underwater control device, which then activates the underwater sonar equipment according to the command. Thus, underwater monitoring can be automatically initiated by the underwater control device to acquire underwater target data.

[0083] Furthermore, the aforementioned integrated monitoring method may further include: an underwater control device acquiring the angle between the underwater sonar equipment and the underwater target; the underwater control device comparing the angle between the underwater sonar equipment and the underwater target with a second preset angle threshold; if the angle between the underwater sonar equipment and the underwater target is greater than the second preset angle threshold, then controlling the underwater sonar equipment to move along a circular track until the angle between the underwater sonar equipment and the underwater target is less than or equal to the second preset angle threshold; the underwater control device acquiring the height difference between the underwater sonar equipment and the underwater target; the underwater control device comparing the angle between the underwater sonar equipment and the underwater target with the second preset angle threshold; and the underwater control device comparing the angle between the underwater sonar equipment and the underwater target with the second preset angle threshold. The system controls the movement of a circular track along the wind turbine foundation until the height difference between the sonar device and the underwater target is less than or equal to the preset height difference threshold. If the height difference between the sonar device and the underwater target is less than or equal to a second preset angle threshold, and the height difference between them is also less than or equal to the preset height difference threshold, the sonar device identifies and tracks the underwater target to obtain its data. Therefore, the underwater control device can be used to adjust the position of the sonar device in real time, enabling accurate and efficient acquisition of target data at different depths in the underwater environment.

[0084] Figure 7 A schematic diagram illustrating the specific implementation process of the monitoring method for the integrated monitoring system for wind turbine generators provided in this embodiment of the disclosure is shown. See also... Figure 7The monitoring process of the wind turbine integrated monitoring system provided in this embodiment may include:

[0085] Radar, passive detection equipment, self-organizing network equipment, fixed anti-drone equipment, optoelectronic equipment, etc. are activated.

[0086] The radar begins sea surface target detection, acquiring the target's approximate location. When the angle between the tail of the nacelle and the target exceeds a first preset angle threshold |A|, the wind turbine's main control system is instructed to control the wind turbine to begin yawing in the direction where the absolute value of the angle between the tail and the target decreases. The wind turbine stops yawing when the angle between the tail of the nacelle and the target falls below the first preset angle threshold |A|. This allows the target to be detected by radar, passive detection equipment, and fixed anti-drone equipment.

[0087] Passive detection equipment simultaneously acquires the target's movement trajectory.

[0088] The photoelectric equipment, combined with the motion trajectory obtained by the passive detection equipment, begins to track the target in real time and starts recording video evidence.

[0089] Fixed anti-drone equipment identifies and jams nearby drones that may pose a threat, ensuring the safety of wind turbine units.

[0090] When the wind turbine has comprehensive monitoring requirements, the first and second monitoring devices in the comprehensive monitoring system operate simultaneously, and the underwater sonar device also starts working at the same time to acquire the angle and depth relative to the underwater target in real time. When the angle between the underwater sonar device and the target is greater than a second preset angle threshold |B|, the underwater control device controls the underwater sonar device to move along a circular track until the angle between the underwater sonar device and the target is less than or equal to the second preset angle threshold |B|. When the difference between the height of the underwater sonar device and the height of the underwater target is greater than a preset height difference threshold |C|, the circular track is controlled to move up and down along the foundation of the wind turbine until the height difference between the underwater sonar device and the underwater target is less than the preset height difference threshold |C|. Once the angle between the underwater sonar device and the target is less than or equal to the second preset angle threshold |B| and the height difference between the underwater sonar device and the underwater target is less than or equal to the preset height difference threshold |C|, the target is determined to be within the detection range of the underwater sonar device. At this point, the underwater sonar device is controlled to begin accurately identifying and tracking the underwater target to obtain information about it.

[0091] As can be seen from the above, the integrated monitoring system and method provided in this disclosure utilize the large-scale deployment, height advantage, and stable continuous power supply capability of wind turbine units to construct an integrated monitoring network covering the sea surface, air, and underwater. By integrating multiple types of monitoring equipment, it can monitor marine environmental anomalies in the wind farm area in real time, such as illegal vessels, pollution sources, and underwater obstacles. This achieves real-time monitoring of the wind farm area from all angles and perspectives, ensuring the safety of wind turbine units and their related marine facilities while improving the efficiency of marine resource management and providing data support for marine environmental protection.
