Description

Technical Field

[0001] This application relates to the field of wind power equipment technology, and in particular to a monitoring device and monitoring system for offshore floating wind turbines. Background Technology

[0002] Floating wind turbine generators are core equipment for deep-sea wind energy development. They are fixed in the open ocean by a floating structure, enabling efficient utilization of high-quality wind energy. Due to the complex environment of the deep sea, the generators are subjected to loads from wind, waves, and ocean currents for extended periods. The attitude of the floating body and the stress on the tower can affect the safety and power generation efficiency of the generators. Therefore, real-time monitoring of the generator status is necessary.

[0003] In related technologies, various sensors such as wind speed, attitude, and strain are usually fixedly installed on the unit. These sensors are usually connected to the unit's power supply system, which provides power to collect and transmit monitoring data to control the unit's operating status.

[0004] However, in extreme weather conditions such as typhoons, floating wind turbines are prone to power outages due to strong winds or safety shutdowns, which renders the sensors inoperable and results in a loss of unit status data during that period. Utility Model Content

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the preferred embodiments of this application will be described in more detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0042] It should be noted that in the description of the embodiments of this application, the terms "upper", "lower", "inner", "outer" and other terms indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description, and do not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application.

[0043] Furthermore, it should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0044] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0045] In related technologies, various sensors such as wind speed, attitude, and strain are usually fixedly installed on floating wind turbine generators. These sensors are usually connected to the generator's power supply system, which provides power to the generator to collect and transmit monitoring data, thereby enabling control over the generator's operating status.

[0046] However, in extreme weather conditions such as typhoons, floating wind turbines are prone to power outages due to strong winds or safety shutdowns, which renders the sensors inoperable and results in a loss of unit status data during that period.

[0047] In view of this, the monitoring device and monitoring system for offshore floating wind turbines provided in this application have a power supply compartment that can store or release electrical energy to continuously power the sensor components, so that the sensor components can continuously collect target monitoring data of the offshore floating wind turbines, thereby realizing real-time monitoring of the status of the offshore floating wind turbines and ensuring the safety of the wind turbines.

[0048] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0049] See Figure 1 This application provides a monitoring device 10 for an offshore floating wind turbine. The monitoring device 10 includes a mounting assembly 100, a power storage compartment 200, a power conversion assembly 300, a sensor assembly 400, and a communication transmission assembly 500. The mounting assembly 100 is used for detachable connection with the functional components of the offshore floating wind turbine. The power storage compartment 200 is disposed on one side of the mounting assembly 100 in a first direction X, and the power storage compartment 200 is capable of storing or releasing electrical energy. See also... Figure 2 The power conversion component 300 is electrically connected to the power supply compartment 200 and is used to convert clean energy into electrical energy. The sensor component 400 is disposed on the side of the power supply compartment 200 opposite to the mounting component 100 in the first direction X. The sensor component 400 includes a sensor compartment 410 and a sensor, which is disposed within the sensor compartment 410 and used to collect target monitoring data of the offshore floating wind turbine. The communication transmission component 500 is disposed on the outer wall of the sensor component 400 and is used to transmit the target monitoring data to the data processing center.

[0050] Here, the first direction X can be understood as the height direction of the monitoring device 10.

[0051] See Figure 3 The mounting component 100 can be detachably connected to the functional components of the offshore floating wind turbine. Optionally, the functional components can be floating external platforms, nacelles, etc. The mounting component 100 can be detachably connected to the functional components through magnetic connection, bolt connection, vacuum adsorption, adhesive connection, etc. This ensures the tightness of the connection between the mounting component 100 and the functional components, effectively preventing the monitoring device 10 from falling off in extreme marine environments such as typhoons and giant waves. It also allows the mounting component 100 to be separated from the functional components to relocate the monitoring device 10 when it is necessary to move the monitoring device 10 (such as adjusting the monitoring position according to monitoring needs, or transferring it to other wind turbines), thereby improving the reusability and flexibility of the monitoring device 10.

[0052] The power supply compartment 200 can be disposed on the side of the mounting assembly 100 opposite to the functional components in the first direction X, that is, the power supply compartment 200 can be disposed above the mounting assembly 100. The sensor assembly 400 and the communication transmission assembly 500 can be electrically connected to the power supply compartment 200, and the power supply compartment 200 can realize the storage and release of electrical energy to provide continuous and stable power to the sensor assembly 400 and the communication transmission assembly 500.

[0053] The power conversion component 300 can be electrically connected to the power storage 200 via wires. Its function is to convert usable clean energy in the marine environment into electrical energy and store it in the power storage 200 to ensure the continuous power supply capability of the power storage 200. The power conversion component 300 can be at least one of a solar energy conversion component or a wind energy conversion component. For example, when the power conversion component 300 includes a solar energy conversion component, it can be installed on the top or side wall of the power storage 200 to ensure its solar energy absorption efficiency. When the power conversion component 300 includes a wind energy conversion component, a miniaturized wind turbine can be used. The power conversion component 300 can be located on top of the monitoring device 10, collecting wind energy, converting it into electrical energy, and then supplying it to the power storage 200. Therefore, through the coordinated operation of the power storage 200 and the power conversion component 300, the sensors of the monitoring device 10 do not need to rely on the power supply system of the offshore floating wind turbine. When the offshore floating wind turbine is damaged by strong winds or shut down due to extreme weather such as typhoons, the power storage 200 can continuously supply power to the sensors, ensuring that the sensors always remain in working condition and effectively avoiding the problem of missing target monitoring data during extreme weather.

[0054] It should also be noted that the sensor assembly 400 can be disposed on the side of the power supply compartment 200 opposite to the mounting assembly 100 in the first direction X. For example, the sensor assembly 400 can be disposed above the power supply compartment 200 and located between the power conversion assembly 300 and the power supply compartment 200. The sensor assembly 400 can include a sensor compartment 410 and sensors disposed inside the sensor compartment 410. The sensor compartment 410 can be a high-strength, waterproof, and shock-resistant sealed housing to effectively prevent seawater infiltration, salt spray corrosion, and damage to the sensors caused by sea waves and vibrations generated during wind turbine operation. The housing can be provided with partitioned mounting chambers, allowing different types of sensors to be installed in different chambers to avoid signal interference between sensors. The type of sensor can be set according to the monitoring requirements of the offshore floating wind turbine, and this embodiment does not limit this.

[0055] The power supply compartment 200 can be a detachable power supply compartment. In the first direction X, the top of the power supply compartment 200 can be connected to the bottom of the sensor compartment 410 by screws, bolts, etc.

[0056] See Figure 1 and Figure 7 The communication transmission component 500 can be installed on the outer wall of the sensor component 400. The communication transmission component 500 can communicate with the sensor component 400 to receive target monitoring data collected by the sensor and transmit the data to the data processing center in real time. This allows maintenance personnel to promptly grasp the transportation or operating status of the offshore floating wind turbine, thereby ensuring the safety of the offshore floating wind turbine. Optionally, the communication transmission component 500 can communicate with the sensor component 400 via wired or wireless means. For example, the communication transmission component 500 can communicate with the sensor component 400 wirelessly. This eliminates the need for wiring between the sensor component 400 and the communication transmission component 500, avoiding the problems of wire corrosion and breakage in the high salt spray and strong vibration environment at sea, reducing the probability of line failure, simplifying the installation process of the monitoring device 10, and allowing for flexible adjustment of the installation position of the communication transmission component 500.

[0057] The communication transmission component 500 may include a 4G antenna and a satellite antenna, and the 4G antenna and satellite antenna may extend on the side away from the battery compartment in the first direction X. The 4G antenna and satellite antenna can continuously transmit the target monitoring data collected by the sensor to the data processing center, providing reliable communication support for the status monitoring of offshore floating wind turbines.

[0058] In practical use, the mounting assembly 100 securely mounts the monitoring device 10 onto the functional components of the offshore floating wind turbine. The power conversion assembly 300 continuously converts clean energy into electrical energy and transmits it to the power storage silo 200 for storage. The power storage silo 200 provides a continuous and stable power supply to the sensor assembly 400 and the communication transmission assembly 500. The sensors in the sensor assembly 400 collect target monitoring data of the offshore floating wind turbine in real time and transmit the target monitoring data to the communication transmission assembly 500. The communication transmission assembly 500 processes the target monitoring data and transmits it to the data processing center, realizing real-time monitoring of the status of the offshore floating wind turbine, timely detection of potential safety hazards, and ensuring the safety of the offshore floating wind turbine.

[0059] In some embodiments, the power storage compartment 200 includes at least one power storage device that is electrically connected to the sensor and is capable of providing power to the sensor.

[0060] Optionally, the energy storage device may include a battery, a capacitor, etc. For example, the battery may include a lead-acid battery.

[0061] It should be noted that the power compartment 200 may include one, two, three or more energy storage devices. Each energy storage device can be set to be independently detachable. When one of the energy storage devices fails, it is not necessary to disassemble the entire power compartment 200. Only the faulty energy storage device needs to be replaced. This can improve maintenance convenience and reduce maintenance costs.

[0062] In addition, the energy storage device is also electrically connected to the energy conversion component 300, and can receive and store the energy converted by the energy conversion component 300. When the external clean energy supply is unstable, it can rely on its own stored energy to continuously power the sensor, thus preventing the sensor from stopping working due to power interruption.

[0063] In some embodiments, the power compartment 200 further includes at least one charging port 210 electrically connected to the energy storage device, the charging port 210 being used to charge the energy storage device after being connected to an external power source.

[0064] The electrical connection between the charging port 210 and the energy storage device can be achieved through a waterproof wire and a sealed terminal to prevent seawater and salt spray from seeping in through the connection gap and causing a short circuit.

[0065] In practice, the external power source can be the electrical cabinet inside the nacelle of a floating offshore wind turbine, or a portable charging device carried on a maintenance vessel. Thus, by charging the energy storage device through the charging port 210, the sensor can be prevented from stopping working due to power depletion.

[0066] In other words, when the monitoring device 10 is installed inside the nacelle of an offshore floating wind turbine, the energy storage device can be charged through the electrical cabinet inside the nacelle. Even if the electrical cabinet inside the nacelle is interrupted due to temporary shutdown of the wind turbine, fault maintenance, or extreme weather, the energy storage device can still power the sensor with its stored energy to ensure continuous monitoring of the wind turbine's operating status.

[0067] See Figure 2 In some embodiments, the power conversion assembly 300 includes a photovoltaic panel 310, which is electrically connected to at least one of a sensor and a power storage device. The photovoltaic panel 310 is capable of converting solar energy into electrical energy and providing power to the sensor and / or the power storage device.

[0068] Understandably, the photovoltaic panel 310 can convert solar energy into electrical energy and provide power to sensors and / or energy storage devices. The installation location of the photovoltaic panel 310 can be flexibly set according to the marine lighting conditions, for example, it can be adapted to be installed on the top of the sensor compartment 410 or on the side of the power supply compartment 200 facing sufficient sunlight.

[0069] For example, the photovoltaic panel 310 can be connected to an energy storage device. When there is sufficient sunlight, the photovoltaic panel 310 transmits electrical energy to the energy storage device. The energy storage device can store excess electrical energy while providing power to the sensor. When the sunlight is weak or at night, the energy storage device can release electrical energy to power the sensor. With this configuration, the energy storage device can provide stable power to the sensor, reducing the probability of fluctuations or interruptions in the sensor's power supply due to changes in lighting conditions. This ensures that the sensor can continuously and reliably collect target monitoring data of the offshore floating wind turbine at different times and under different lighting conditions, guaranteeing the continuity and integrity of the monitoring process.

[0070] In some alternative embodiments, the power conversion assembly 300 includes a wind power converter that is electrically connected to at least one of the photovoltaic panel 310 and the sensor and the power storage device. The wind power converter is capable of converting wind energy into electrical energy and providing power to the sensor and / or the power storage device.

[0071] Optionally, the wind energy conversion device may include a miniaturized wind turbine, which may be located on top of the monitoring device 10 to facilitate the collection of wind energy.

[0072] For example, the wind energy converter can be connected to an energy storage device. When the wind is strong, the wind energy converter delivers electrical energy to the energy storage device. The energy storage device can store excess electrical energy while providing power to the sensor. When the wind is weak or there is no wind, the energy storage device can release electrical energy to power the sensor. With this configuration, the energy storage device can provide a stable power supply to the sensor, ensuring that the sensor can continuously and reliably collect target monitoring data of the offshore floating wind turbine under different wind conditions.

[0073] In some embodiments, the power conversion component 300 further includes a charge / discharge controller for distributing the electrical energy converted by the power conversion component 300.

[0074] It should be noted that the charge / discharge controller can monitor the power output status of the power conversion component 300, the remaining power of the energy storage device, and the real-time power consumption of the sensor in real time, and then dynamically allocate power. Specifically, when the power conversion component 300 outputs sufficient power, the charge / discharge controller can direct the power to the sensor and direct excess power to the energy storage device for storage; when the clean energy supply is insufficient (such as weak light or low wind), the charge / discharge controller mobilizes the energy storage device to release power to the sensor.

[0075] In addition, the charge and discharge controller can integrate overcharge, over-discharge, and overcurrent protection modules to ensure the stable operation of the power conversion component 300 and the power supply compartment 200.

[0076] In some embodiments, a level detection element is provided outside the power supply compartment 200, which is used to detect the levelness of the monitoring device 10.

[0077] Optionally, the level detection element may include at least one of a level bulb and an electronic level. The level detection element may be positioned at the top of the power supply compartment 200 for easy observation of the levelness.

[0078] By setting a level detection element, the monitoring device 10 can be leveled before it is installed on the functional component, ensuring the consistency between the sensor's acquisition reference and the preset monitoring dimension, and reducing the probability of deviation in the acquisition of target monitoring data due to the tilt of the monitoring device 10.

[0079] See Figure 4 In some optional embodiments, the power supply compartment 200 is also provided with a power display 220, an output interface 230, and a switch 240 for controlling the on / off state of the output interface 230.

[0080] The power indicator 220, output interface 230, and switch 240 can all be located on the outer wall of the power compartment 200.

[0081] Understandably, the power display 220 can use a display panel to allow maintenance personnel to view the remaining power of the energy storage device.

[0082] The output interface 230 can be connected to the sensor compartment 410 via a wire to enable the energy storage device to supply power to the sensor. During operation and maintenance, the on / off state of the output interface 230 can be controlled by the switch 240 to improve the convenience of operation and maintenance.

[0083] In some embodiments, the sensor compartment 410 contains various types of sensors, including at least one of the following: gyroscope, accelerometer, temperature sensor, humidity sensor, positioning sensor 420, atmospheric corrosion sensor, corrosion rate sensor, and meteorological sensor.

[0084] It is understood that one or more of the aforementioned sensors can be installed inside the sensor compartment 410. See also Figure 7 and Figure 8 Some of these sensors (such as positioning sensor 420, humidity sensor, atmospheric corrosion sensor, etc.) can be mounted outside the sensor housing 410 to facilitate accurate acquisition of corresponding target monitoring data. Figure 9 and Figure 10 They are respectively Figure 7 Side view and top view.

[0085] Among them, gyroscopes can be used to collect attitude data (such as tilt angle and rotational angular velocity) of offshore floating wind turbines, so as to detect abnormal attitude deviations of wind turbines caused by wave impact and strong winds in a timely manner, and avoid structural instability or overturning of wind turbines.

[0086] Accelerometers can be used to collect the vibration acceleration of floating offshore wind turbines in order to determine whether the wind turbines have suffered fatigue damage due to excessive vibration.

[0087] Temperature sensors can be used to collect temperature data; humidity sensors can be used to collect humidity data, so that maintenance personnel can promptly detect the risk of condensation in high humidity environments and ensure the stable operation of wind turbines.

[0088] The positioning sensor 420 is used to collect real-time position coordinate data of the wind turbine, aiming to monitor whether the wind turbine is abnormally drifting due to ocean currents or storm surges, and to prevent the wind turbine from deviating from the preset operating area. Optionally, the positioning sensor 420 may include a GPS locator. The atmospheric corrosion sensor is used to collect data on the concentration and corrosion intensity of corrosive media (such as salt spray and sulfides) in the marine atmosphere. Optionally, the atmospheric corrosion sensor may include a resistance probe. The corrosion rate sensor is used to obtain the corrosion progress of the wind turbine, avoiding a decrease in the structural strength of the wind turbine due to corrosion. For example, the corrosion rate sensor may include an electrochemical noise sensor. The meteorological sensor is used to collect meteorological data such as atmospheric pressure, ultraviolet radiation, and oxygen in the operating area, assisting the wind turbine in adjusting its operating status and reducing the risk of damage to the wind turbine from extreme weather.

[0089] Therefore, the target monitoring data can include attitude data, vibration acceleration, temperature data, humidity data, location coordinate data, corrosive medium concentration and corrosion intensity data, corrosion rate, and meteorological data of the offshore floating wind turbine. This target monitoring data can reflect the status information of the offshore floating wind turbine throughout its entire lifecycle, including towing, installation, operation, and maintenance, providing data support for the subsequent design, transportation, and maintenance services of the offshore floating wind turbine. For example, when the monitoring device 10 is installed in the nacelle, it can collect target monitoring data from the top of the offshore floating wind turbine tower, thereby reflecting the impact of the floating external platform on the wind turbine itself, facilitating the optimization of the design of equipment within the nacelle.

[0090] In some alternative embodiments, the sensor assembly 400 also includes a processor capable of performing preliminary data processing and storage on the sensor; that is, the processor can convert the sensor's electrical signals into digital signals to transmit the target monitoring data to a data processing center.

[0091] Furthermore, the processor can control the activation and deactivation of each sensor and the frequency of target monitoring data transmission to the data processing center, thereby saving energy consumption in the power storage compartment 200. For example, during typhoon weather, the monitoring device 10 can be controlled to enter typhoon warning mode, switching it to a standby state of <0.1W. In this state, only some sensors (such as accelerometers and gyroscopes) can be controlled. The processor can also control the frequency of target monitoring data transmission to the data processing center. For instance, a preset threshold can be set internally. When the target monitoring data collected by the sensors exceeds the preset threshold, the target monitoring data is then transmitted to the data processing center via the communication transmission component 500. This reduces energy waste in the power storage compartment 200 caused by frequent transmission of target monitoring data.

[0092] See Figure 4 In some embodiments, multiple mounting components 100 are spaced apart. Each mounting component 100 includes a support leg 110 and a connecting layer 120. The support leg 110 is telescopically adjustable in height, and the connecting layer 120 is disposed at the bottom of the support leg 110 and connected to the surface of the functional component.

[0093] Multiple mounting components 100 are spaced apart to evenly distribute the overall weight of the monitoring device 10, while also adapting to the surfaces of functional components, thus improving the overall stability of the monitoring device 10 after installation. Optionally, the mounting components 100 can be three, four, or other configurations.

[0094] The support rod 110 can be a telescopic rod, and the height can be adjusted by manually or with tools to adjust the telescopic length. After adjustment, the length can be fixed by locking parts (such as fastening bolts).

[0095] In some embodiments, the connecting layer 120 includes at least one of the following: a magnetic mounting surface, a bolt connection surface, a vacuum adsorption surface, and an adhesive connection surface.

[0096] It should be noted that the magnetic mounting surface can be made of highly magnetic material, compatible with the metal surface of the functional components, and can be quickly adsorbed and fixed without drilling. It can also be quickly separated from the functional components during later maintenance.

[0097] The bolted connection surface can be connected to the functional component via bolts, thereby achieving a detachable connection between the monitoring device 10 and the functional component. The vacuum adsorption surface can have an elastic sealing lip at its edge and a pre-reserved vacuum channel inside. After being attached to the surface of the functional component, a vacuum is created to generate negative pressure, achieving adsorption and allowing the connecting layer 120 to adhere to the surface of the functional component. The adhesive connection surface can include adhesive, which, after bonding, forms a stable bond, thereby achieving the connection between the monitoring device 10 and the functional component.

[0098] See Figure 5 and Figure 6In some embodiments, a handling aid 600 is provided on each of the opposite sides of the power supply compartment 200.

[0099] Optionally, the handling aid 600 may include a concave grip groove, a U-shaped handle, etc., and its surface may be provided with an anti-slip layer. By setting the handling aid 600, a force fulcrum can be provided for the handling of the monitoring device 10, so as to facilitate the relocation of the monitoring device 10 and improve the convenience and safety of the handling operation of the monitoring device 10 in the marine operation and maintenance scenario.

[0100] In some alternative embodiments, the monitoring device 10 further includes a plurality of support rods 700 disposed on the side of the power compartment 200 away from the mounting assembly 100 in the first direction X. The power conversion assembly 300 is connected to each support rod 700, and the orthographic projection of the power conversion assembly 300 in the first direction X covers at least a portion of the power compartment 200.

[0101] It is understandable that the support rods 700 can be set to two, three, or other configurations. By setting multiple support rods 700, a stable connection between the power conversion component 300 and the power supply compartment 200 can be achieved. At the same time, by having the orthographic projection of the power conversion component 300 in the first direction X cover at least a portion of the power supply compartment 200, the space above the power supply compartment 200 can be fully utilized to install the power conversion component 300, thereby improving the integration of the monitoring components.

[0102] In addition, some support rods 700 can be configured to adjust their height so as to optimize the angle of the power conversion component 300 relative to the power compartment 200 according to the light or wind direction.

[0103] In some embodiments, the functional component includes at least one of the following: a floating external platform or a cabin.

[0104] The floating external platform serves as the foundational support structure for offshore floating wind turbines. The monitoring device 10 is installed on the floating external platform to collect data such as attitude deviation and structural stress, providing a basis for assessing the stability of the floating external platform.

[0105] The nacelle can accommodate the wind turbine generator, gearbox, etc. When the monitoring device 10 is installed in the nacelle, it can collect target monitoring data on the top of the offshore floating wind turbine tower, thereby reflecting the impact of the floating external platform on the wind turbine itself.

[0106] Based on the above embodiments, this application provides a monitoring system for offshore floating wind turbines, including a monitoring device 10 and a data processing center provided in any of the above embodiments. The data processing center includes a data processor and a display device. The data processor is used to receive and process target monitoring data sent by the monitoring device 10. The display device is used to display early warning information, which indicates that an abnormality exists in the offshore floating wind turbine based on the target monitoring data.

[0107] The display device may include at least one of a mobile phone, a tablet computer, an industrial control display, or a laptop computer.

[0108] The data processor receives and processes target monitoring data sent by the monitoring device 10. Specifically, through IoT technology, the target monitoring data collected by the sensor can be transmitted to the data processor in real time using the communication transmission component 500. The data processor can store, analyze, and process the target detection data. The transmission rate can be selected from 0.2Hz to 200Hz. Optionally, the target monitoring data may include the sensor's serial number, acceleration, angular velocity, angle, magnetic field, latitude and longitude, GPS heading angle, GPS speed, positioning accuracy, number of satellites, battery compartment voltage, cellular signal quality (CSQ), temperature, data upload interval, on-chip time, software version, etc.

[0109] Data processors can perform real-time analysis of collected target monitoring data. For example, thresholds for relevant parameters can be set in the data processing center. When the temperature or humidity exceeds the preset threshold, the data processing center will immediately issue an early warning. Simultaneously, data processors can also perform statistical analysis on target monitoring data. Common methods include descriptive statistics (such as mean and frequency), inferential statistics (such as hypothesis testing), trend analysis, correlation analysis, and clustering / classification to identify potential problems, such as slow tilting, abnormal vibration, and abnormal displacement of the offshore floating wind turbine platform. When abnormal conditions occur in the offshore floating wind turbine, the data processor will transmit early warning information to the display device, alerting maintenance personnel so that they can take timely measures, such as adjusting the environmental conditions of the offshore floating wind turbine or reinforcing the offshore floating wind turbine.

[0110] In practical implementation, the data processor can perform multi-level analysis and early warning of various types of target monitoring data. For example, the data processor can first determine whether the acceleration exceeds a preset threshold. If the acceleration exceeds the preset threshold, it can then determine whether the angular velocity exceeds a preset threshold. If the angular velocity also exceeds a preset threshold, it can then determine whether the displacement of the offshore floating wind turbine exceeds a preset threshold. If the displacement of the offshore floating wind turbine also exceeds a preset threshold, an early warning message is generated and displayed to remind maintenance personnel. Therefore, by analyzing various types of target monitoring data, the data processor can comprehensively assess the status of the offshore floating wind turbine, reducing the probability of misjudgment.

[0111] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
