[0002] As an important marine meteorological element, wind is of vital importance to the study of changes in ocean climate and the generation of waves. Direction and speed need to be identified during offshore operations. Traditionally, there are two methods for measuring airflow direction and speed: multi-hole probe measurement and hot wire and hot film measurement. Common types of wind speed and direction sensors currently available on the market include mechanical wind speed and direction sensors, ultrasonic wind speed and direction sensors, and photoelectric wind speed and direction sensors. When using these sensors for unmanned sea operations, the following problems exist: limited monitoring range, limited real-time response, and low equipment stability.

DETAILED DESCRIPTION

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0025] See also Figure 1-Figure 3 , the following describes a low-cost ocean wind speed and direction sensor mechanism based on noise inversion according to some embodiments of the present invention.

[0026] The embodiment of the first aspect of the present invention provides a low-cost ocean wind speed and direction sensor mechanism based on noise inversion. In some embodiments of the present invention, such as Figure 1-Figure 3 As shown, the ocean wind speed and direction sensor mechanism includes: The first detection unit is arranged above the sea surface; the first detection unit includes a first sensor, and the first sensor is used to obtain first wind speed data of ocean wind on the sea surface.

[0027] The second detection part floats on the sea surface and is connected to the first detection part through a connecting rod 9 ; the second detection part includes a plurality of second sensors, and the second sensors are arranged along the circumference of the connecting rod 9 .

[0028] Among them, the end of the connecting rod 9 away from the first detection part is elastically connected to the inside of the second detection part, so as to drive the connecting rod 9 to swing when the ocean wind flows through the first detection part, and obtain the second wind speed data and wind direction data of the ocean wind through the cooperation between the connecting rod 9 and the second sensor.

[0029] This invention provides a low-cost ocean wind speed and direction sensor mechanism based on noise inversion. The primary function of the first detection unit is to monitor and record the wind speed above the sea surface. This unit is typically located above the sea surface to ensure direct access to the ocean wind, thereby obtaining accurate wind speed data. This data is crucial for fields such as meteorological analysis, oceanographic research, navigation safety, and climate monitoring. The first sensor is the core of the first detection unit, responsible for capturing and converting sea surface wind speed information.

[0030] The first sensor can measure wind speed by sensing pressure changes caused by air flow or by utilizing other meteorological measurement technologies, such as ultrasonic sensors and pitot tubes. The specific measurement principles vary depending on the sensor type: pressure sensors use pressure differences to determine wind speed. The greater the wind speed, the greater the pressure difference. Ultrasonic sensors determine wind speed by measuring changes in the speed of sound waves traveling through the air. The propagation time of ultrasonic waves in the wind varies with wind speed, allowing accurate calculation of wind speed. Pitot tubes measure pressure changes caused by the wind speed entering the tube and use this data to calculate wind speed. After the first sensor captures wind speed data, it is typically converted into an electrical signal and sent to a data processing unit, which analyzes and processes the signal, converting it into usable wind speed data. This data can then be displayed on a monitoring system or transmitted to a remote database for further analysis and storage. The resulting wind speed data can be used for immediate weather updates or as part of long-term climate monitoring.

[0031] The second detection unit is designed to provide more comprehensive and detailed sea surface wind speed and direction data through multiple second sensors arranged circumferentially along the connecting rod 9; the second detection unit is designed to float on the sea surface, which enables it to directly interact with the sea surface wind and receive wind data from multiple angles; by evenly arranging multiple second sensors around the connecting rod 9, the second detection unit can capture wind speed and direction information from different directions, which is helpful for a comprehensive assessment of wind field characteristics; the second detection unit is connected to the first detection unit through the connecting rod 9, so that the data of the two parts can verify and complement each other, thereby improving the accuracy and reliability of the overall measurement.

[0032] Secondary sensors measure wind speed and direction through physical or acoustic methods. These sensors may use technologies similar to those used in the primary sensor (e.g., pressure differential, ultrasound, thermal wire, etc.), or employ other technologies specific to their placement and functionality. The circumferential arrangement of sensors along connecting rod 9 allows for 360-degree capture of wind dynamics, a highly useful feature for assessing complex wind fields. Data collected from the multiple sensors in the secondary sensor is synchronized and transmitted to a central data processing unit, which analyzes the data from each sensor and uses algorithms to integrate and correct the data to provide accurate wind speed and direction readings. The configuration of the secondary sensor connected to the primary sensor via connecting rod 9 also enables it to dynamically respond to changes in wind force and direction. For example, wind force may cause the connecting rod 9 to oscillate slightly, which is captured by the sensors and converted into wind direction data.

[0033] The elastic connection of the second detection unit allows the connecting rod 9 to swing under the influence of wind. This swing not only captures wind speed but also directly reflects wind direction through its direction and amplitude. Measuring wind parameters through dynamic swing reduces the limitations of fixed measurement points and provides more comprehensive wind field information.

[0034] When the ocean wind flows through the first detection section, the force of the wind is captured by the first sensor, causing a propulsion force to be applied to the connecting rod 9. Because the connecting rod 9 is connected to the interior of the second detection section via an elastic element (such as a spring), this propulsion force is converted into a swinging motion of the connecting rod 9. The swing amplitude and frequency of the connecting rod 9 will reflect the strength and stability of the wind, and the swing direction provides wind direction information. Second sensors arranged circumferentially along the connecting rod 9 measure and calculate wind speed and direction based on the swing angle and speed changes of the connecting rod 9. The second sensors may use angle encoders, gyroscopes, or other angle sensing devices to accurately capture the swing data of the connecting rod 9. All sensor data from the second detection section is synchronized and sent to a central data processing unit. The data processing unit integrates the data from the first and second detection sections through algorithms to provide more accurate and comprehensive wind speed and direction information.

[0035] In summary, the use of a design based on noise inversion technology reduces reliance on high-end sensors and complex mechanical components, significantly reducing manufacturing and maintenance costs. This makes the sensor system more economical and easier to deploy on a large scale. By combining the data from the first and second detection units, highly accurate and comprehensive wind speed and direction measurements can be provided. The elastic connection of the second detection unit and the design of the connecting rod 9 allow for accurate capture of dynamic changes in the wind, thereby improving the sensitivity and response speed of the overall measurement. The sensor mechanism design takes into account the challenges of the marine environment, such as salt spray corrosion, water surface fluctuations, and other severe weather conditions. The floating design and internal elastic connection ensure the stability and durability of the equipment in complex environments. The multiple second sensors arranged circumferentially along the connecting rod 9 of the second detection unit provide 360-degree wind direction monitoring capabilities, which is very important for a comprehensive understanding and analysis of wind field characteristics. The technology relied on is mature and reliable, and can be easily deployed in ocean areas far from the shore. At the same time, low maintenance requirements reduce the complexity and cost of long-term operations.

[0036] In any of the above embodiments, the second detection part also includes a second detection ball 4 and an internal float 5, and the outer wall of the internal float 5 is slidingly connected to the inner wall of the second detection ball 4 to avoid or weaken the shaking of the second detection ball 4 caused by external waves and the synchronous shaking of the internal float 5.

[0037] The middle part of the internal float 5 is recessed in the direction away from the first detection part, and an inner groove is formed. The center of gravity of the internal float 5 in the second detection ball 4 can be effectively lowered by recessing axially downward along the connecting rod 9; one end of the connecting rod 9 located inside the second detection ball 4 and the second sensor are respectively connected to the inner wall of the inner groove to perform real-time detection of the swing of the connecting rod 9 caused by the action of ocean wind.

[0038] In this embodiment, the main purpose of the design of the second detection ball 4 is to keep the second sensor stable so that it can accurately measure the wind speed and direction even under severe waves and wind. By reducing the direct impact of external waves on the internal float 5, the system can avoid measurement errors introduced by the shaking of the internal float 5 with the waves, thereby ensuring the accuracy and reliability of the data.

[0039] The second detection sphere 4 is designed with a sturdy outer shell that floats on the water surface, protecting the multiple secondary sensors and electronic equipment inside from seawater erosion and physical damage. An internal float 5 is mounted inside the second detection sphere 4, with its outer wall sliding on the inner wall of the sphere. This sliding connection allows the internal float 5 to move freely within a certain range without completely separating from the outer shell. When external waves act on the second detection sphere 4, the outer shell may shake or shift. Because the internal float 5 is slidingly connected to the outer shell, this design allows the internal float 5 to maintain a stable relative position. Even if the outer shell moves or tilts due to wave action, this relatively independent internal structure significantly reduces the impact of environmental factors on the measurement accuracy of the second sensors. The design of the internal float 5 not only provides physical protection but also acts as a shock absorber. In the marine environment, shock absorption is critical for maintaining data accuracy. By protecting the internal second sensors from the harsh effects of the marine environment, such as saltwater corrosion and marine organism adhesion, the second sensors can operate in a relatively stable environment, thereby improving the accuracy and repeatability of measurement data.

[0040] The inner groove formed by the downward depression in the middle of the internal float 5 can help concentrate the mass of the float, reduce unnecessary swinging caused by sea surface fluctuations, and enhance the overall stability; the connecting rod 9 and its associated second sensor are connected to the inner wall of the inner groove. This arrangement makes the second sensor closer to the center of mass of the device, thereby improving the detection accuracy of the swing.

[0041] The groove formed by the depression in the middle of the internal float 5 is designed to lower the center of mass of the system, reduce the impact of external environmental changes on the measuring equipment, and make it more stable; one end of the connecting rod 9 is fixed to the inner wall of the inner groove inside the second detection ball 4. This design allows the swing of the connecting rod 9 under the action of wind to be directly transmitted to the second sensor; when the ocean wind blows the first detection part, the power will be transmitted to the second detection part through the connecting rod 9. Since the connecting rod 9 is directly connected to the inner wall of the inner groove, any swing caused by the wind will cause the connecting rod 9 to move in the inner groove, and this swing will be captured immediately by the second sensor. Since the second sensor is installed on the connecting rod 9, close to the position of the inner groove, it can very accurately measure and feedback the size and direction of the swing.

[0042] In any of the aforementioned embodiments, a hollow cavity 401 is formed between the outer wall of the inner float 5, facing away from the inner groove, and the inner wall of the second detection ball 4. The hollow cavity 401 is located circumferentially around the inner float 5. The spacing of the hollow cavities 401 allows for dimensional redundancy to ensure normal relative sliding or rotation between the inner float 5 and the second detection ball 4, even when temperature fluctuations in seawater affect their thermal expansion and contraction.

[0043] In this embodiment, the hollow cavity 401 provides additional space, allowing the internal float 5 to maintain normal sliding or rotation when it expands or contracts due to temperature, avoiding direct contact and possible jamming; the hollow cavity 401 can not only cope with temperature changes, but also absorb and buffer vibrations or impacts caused by the marine environment, protecting the internal structure from damage; by forming a hollow cavity 401 between the internal float 5 and the second detection ball 4, hard contact can be reduced, the service life of the equipment can be extended and the reliability can be improved.

[0044] The inner float 5 is designed around a central axis, extending outward. Its center is defined by an inner groove. A hollow cavity 401 is located between the outer wall of the inner float 5 and the inner wall of the second detection sphere 4, circumferentially surrounding at least a portion of the inner float 5. In marine environments, temperatures fluctuate frequently, especially in deep water or extreme climates. Due to their material properties, the second detection sphere 4 and the inner float 5 experience thermal expansion and contraction. The hollow cavity 401 allows the second detection sphere 4 and the inner float 5 to expand or contract freely at different temperatures without interfering with or causing the two structures to become stuck. The design of the hollow cavity 401 ensures that even under extreme temperature fluctuations, the inner float 5 can still slide or slightly rotate within the second detection sphere 4, ensuring proper operation of the second sensor. This free movement helps maintain the accuracy of the second sensor, especially when the sensor relies on precise position and angle to measure wind speed and direction. Under the influence of ocean winds or waves, the second detection sphere 4 may move or sway. The presence of the hollow cavity 401 reduces the possibility of external forces being directly transmitted to the inner float 5, thereby reducing the risk of misoperation and damage.

[0045] In any of the above-described embodiments, the interior of the hollow cavity 401 is filled with a first counterweight. The first counterweight circumferentially surrounds the inner float 5 and is eccentrically disposed with respect to the second detection ball 4 to prevent rotation of the inner float 5 when the connecting rod 9 swings. The provision of the first counterweight not only increases the bottom counterweight, contributing to overall stability, but also prevents or reduces steady-state disturbances to the inner float 5 caused by the swing of the connecting rod 9, thereby improving the accuracy of detecting the swing of the connecting rod 9.

[0046] In this embodiment, by adding a counterweight at the bottom, the stability of the entire second detection ball 4 is enhanced, especially when it is affected by wind and waves on the sea surface, it can better maintain its balance and positioning; the first counterweight is effectively blocked and reduced by its eccentric setting. The direct impact of the swinging of the connecting rod 9 on the internal float 5 reduces the impact of external disturbances on the steady state of the internal float 5.

[0047] The first counterweight circumferentially wraps around the center of the inner float 5 but is eccentrically positioned relative to the second detection ball 4. This design not only increases the overall downward force of the counterweight but also helps adjust and control the dynamic behavior of the inner float 5 through its strategic placement. The first counterweight fills the interior of the hollow cavity 401 and surrounds the inner float 5. This filling increases the density of the overall structure and lowers the center of gravity, helping to stabilize the entire device. When the connecting rod 9 swings due to wind force, the eccentric setting of the first counterweight effectively prevents the inner float 5 from excessive rotation or swinging. This is achieved by increasing static friction or creating a damping effect, relying on physical contact between the first counterweight and the inner walls of the inner float 5 and the second detection ball 4. By limiting irrelevant movement of the inner float 5, the first counterweight ensures that all dynamics transmitted by the connecting rod 9 are direct responses to wind swings, rather than non-target movements caused by waves or other environmental factors. This makes the swing data captured by the connecting rod 9 and the second sensor more accurate, directly reflecting the effects of wind. Because the movement of the internal float 5 is effectively controlled, the sensor can more accurately detect the swing of the connecting rod 9, thereby improving the quality and reliability of the data. When processing this data, we can be more confident that it reflects the actual environmental conditions, rather than misinterpretations caused by internal structural instability.

[0048] Furthermore, the first counterweight may be liquid, and its density is lower than that of seawater, so as to provide buoyancy while filling the interior of the hollow cavity 401. The liquid may be mineral oil, silicone oil or vegetable oil.

[0049] From the above, it can be seen that using a liquid with a density less than that of seawater as a counterweight can provide the necessary buoyancy while increasing the sinking weight, which helps to adjust the floating and sinking balance of the entire device; the liquid counterweight can flexibly fill the interior of the hollow cavity 401 and adapt to the shape and volume changes of the internal space, which is particularly effective for dimensional changes caused by temperature.

[0050] Because the liquid has a lower density than seawater, it provides a certain amount of buoyancy for the second sensing ball 4, helping to maintain the device's stability and proper buoyancy depth on the water surface. Furthermore, because the liquid has its own weight, it can also serve as a counterweight, helping to maintain the device's bottom center of gravity and enhancing stability. The liquid exhibits excellent adaptability to thermal expansion and contraction, flowing freely to accommodate changes in the shape and volume of the internal container. When temperature fluctuations cause the materials of the second sensing ball 4 and the internal float 5 to expand or contract, the liquid naturally adjusts its distribution to avoid stress on the internal structure. This self-regulating property helps maintain the freedom of movement of internal mechanical components and prevent damage or malfunction due to excessive pressure. The liquid's fluidity allows it to provide a liquid cushion between the internal float 5 and the second sensing ball 4. This effectively reduces mechanical friction and resistance, especially when the internal float 5 needs to make minor adjustments or rotations relative to the second sensing ball 4. This cushioning layer also absorbs some external vibration or impact, reducing the potential impact of these factors on the accuracy of the second sensor. The fluidity of the liquid counterweight provides a more sensitive response when the connecting rod 9 swings due to wind. It allows the internal float 5 to adjust its position more smoothly to adapt to the dynamic changes of the connecting rod 9, thereby improving the response speed and measurement accuracy of the entire system to wind changes.

[0051] Furthermore, a second counterweight 8 is installed on the bottom outer wall of the second detection ball 4 through a connecting chain 7 .

[0052] As can be seen from the above, the second counterweight 8 increases the total weight of the second detection ball 4, especially at its bottom, which helps to lower the center of gravity of the device and make it more stable in the marine environment; reduces shaking caused by wind and waves: the lowering of the center of gravity and the increased mass help to reduce shaking caused by wind or waves, and improve the measurement accuracy and reliability of the measuring equipment; the heavier bottom can reduce the impact of ocean currents on the position of the second detection ball 4, maintaining its relatively fixed monitoring position.

[0053] By adding a second counterweight 8 to the bottom, the center of gravity of the second detection sphere 4 is effectively lowered. A lower center of gravity makes the entire structure more stable underwater, especially when subjected to upper-level wind or current disturbances. This lower center of gravity helps keep the device upright and prevent it from tipping over or swinging excessively in turbulent ocean conditions. The connecting chain 7 allows the second counterweight 8 to move freely within a certain range, increasing the stability of the system without sacrificing flexibility. Under the influence of waves or wind, the dynamic adjustment of the second counterweight 8 helps the entire device maintain balance and reduce unnecessary shaking. This free-hanging design allows the second counterweight 8 to adjust its position as needed to maximize resistance to unstable swings caused by external forces. By reducing the overall device sway, the internal second sensor can more accurately record data. When the device remains relatively stationary, the data recorded by the second sensor better reflects the actual environmental conditions rather than the device's own dynamics. The added weight of the second counterweight 8 also helps anchor the device in a specific area. This is crucial for long-term monitoring or collecting data in a specific area, preventing the device from being carried away from its original location by currents or strong winds.

[0054] In any of the above embodiments, the second sensor is a piezoelectric sensor 3. Each piezoelectric sensor 3 includes a piezoelectric sheet disposed within an inner groove. A first gap is formed between the piezoelectric sheet and the outer wall of the connecting rod 9. All of the first gaps form an annular cavity along the circumference of the connecting rod 9. The annular cavity formed by the first gaps creates a gap between the piezoelectric sheet and the connecting rod 9, preventing detection results from even slight swings, reducing the number of detections of subtle ocean winds, and lowering power consumption within the device.

[0055] The annular cavity is used for the first detection part to drive the connecting rod 9 to swing, and the wind force detection will be triggered only when the connecting rod 9 crosses the annular cavity, contacts the piezoelectric piece and applies a force.

[0056] In this embodiment, the piezoelectric sheet can very sensitively detect the pressure changes caused by the wind acting on the connecting rod 9, and this change is used to calculate the wind speed and direction; by setting the annular cavity formed by the first gap, a gap is formed between the piezoelectric sheet and the connecting rod 9, which reduces the response to small or insignificant wind forces, thereby reducing the number of false triggers and overall energy consumption; the gap in the design helps prevent false detection due to non-target movement of the connecting rod 9 (such as shaking caused by waves).

[0057] A piezoelectric plate is a material that converts mechanical pressure into an electrical signal. When the connecting rod 9 moves or bends due to wind, this force acts on the piezoelectric plate, generating a voltage change. This change is captured by the sensor and converted into wind speed and direction data. The first gap ensures a certain physical distance between the piezoelectric plate and the connecting rod 9, sufficient to prevent the piezoelectric plate from being activated by every small swing of the connecting rod 9. Only when the swing reaches a certain force and range will the piezoelectric plate sense sufficient pressure change to react. All the first gaps are combined to form an annular cavity along the circumference of the connecting rod 9. This structural design enhances overall balance and responsiveness to environmental changes. The presence of the annular cavity ensures that the piezoelectric plates are evenly distributed around the connecting rod 9, fully capturing the wind's impact on the connecting rod 9. Thanks to the presence of the first gap, the system can filter out insignificant wind effects and only respond to winds of sufficient strength. This reduces frequent data recording and transmission, thereby reducing the device's energy consumption; in the absence of significant wind, the system does not generate unnecessary data processing and power consumption, which helps improve the overall system's efficiency and endurance.

[0058] The annular cavity provides the necessary physical space for connecting rod 9, allowing it to swing freely when subjected to wind without immediately contacting the piezoelectric plate, thus preventing it from reacting to slight or insignificant wind forces. The annular cavity is sized so that only when the connecting rod 9 swings a certain amount can it contact and apply force to the piezoelectric plate, thereby triggering wind detection. This design essentially sets a natural "threshold" for the system, ensuring that only wind of sufficient strength triggers a reaction, reducing the risk of false triggers.

[0059] When wind forces act on the first detection unit, this force is transmitted through connecting rod 9, causing it to oscillate. The annular cavity provides ample space for connecting rod 9 to oscillate freely before reaching a threshold, without contacting the piezoelectric patch. This design allows connecting rod 9 to move within a certain range without triggering any secondary sensor response, which is crucial for preventing data recording from being disrupted by slight wind forces or other non-target interference (such as waves or ship motion). Only when the swing of connecting rod 9 is large enough for one end to pass through the annular cavity and contact the piezoelectric patch will sufficient force be applied to the piezoelectric patch to generate an electrical signal. This applied force indicates sufficient wind force to be recorded and analyzed by the system. The pressure sensed by the piezoelectric patch is converted into an electrical signal, which is then transmitted to a data processing unit for wind speed and direction calculation. Through this mechanism, the system can more accurately measure significant wind events and reduce unnecessary data processing caused by ambient noise or minor swings. Once triggered, the electrical signal generated by the piezoelectric patch is immediately analyzed, ensuring real-time and accurate data, thereby providing reliable information for meteorological monitoring.

[0060] In any of the above embodiments, when the connecting rod 9 applies pressure to at least one piezoelectric sheet, the piezoelectric sheet acquires pressure data applied by the connecting rod 9 .

[0061] The pressure data is used to generate the second wind speed data and wind direction data. By detecting different pressure data through the piezoelectric plate, the direction of the ocean wind can be determined, and the specific pressure data can be used to summarize the wind force in the current direction.

[0062] In this embodiment, the piezoelectric patch directly measures the pressure exerted by the connecting rod 9. This pressure is typically caused by the swinging of the connecting rod 9 due to wind, and the piezoelectric patch's response is used to calculate the strength and direction of the wind. The piezoelectric patch converts the detected physical pressure into electrical signals, which can be quantified and used for further data processing and analysis.

[0063] Piezoelectric plates operate based on the piezoelectric effect, a property of certain materials (such as quartz, certain ceramics, and plastics) that generates a voltage when subjected to mechanical stress. When these piezoelectric materials are compressed or stretched, changes in their internal structure cause a redistribution of charge, generating a voltage. In the system, when the connecting rod 9 swings and contacts the piezoelectric plate, the applied force compresses the piezoelectric plate, causing a voltage change. The piezoelectric plate senses the pressure and generates an electrical signal proportional to the applied force. These signals are transmitted to the system's data processing unit, which converts them into digital data reflecting the intensity of the pressure, which is used to calculate wind speed and direction. The data processing unit analyzes the received data to determine wind behavior characteristics, such as wind speed and direction. These analysis results are very important for weather forecasting, environmental monitoring and related decision-making. The system also includes software tools that can visualize data and provide a user-friendly interface to display information such as wind speed and direction. The system design can include threshold settings. The piezoelectric piece will only respond when the applied pressure exceeds the preset threshold, which helps to reduce the impact of background noise and minor interference. In this way, the system ensures that only significant wind events are recorded and analyzed, improving the efficiency and accuracy of overall monitoring.

[0064] By detecting the pressure applied by connecting rod 9 to the piezoelectric patch in different directions, the direction of the wind can be determined. Different piezoelectric patches correspond to different sides of connecting rod 9, so by comparing the pressure received by these patches, the specific direction of the wind can be determined. The magnitude of the pressure is proportional to the wind speed. By measuring the pressure applied to the piezoelectric patch, the wind speed can be calculated. Greater pressure means stronger wind.

[0065] When wind forces act on the device, causing the connecting rod 9 to swing, the connecting rod 9 compresses specific piezoelectric plates in the direction of the wind. When compressed, the piezoelectric effect causes the movement of internal charge to generate a voltage. This voltage signal is captured and converted into a digital signal for subsequent data processing. The piezoelectric plates are evenly distributed along the circumference of the connecting rod 9, and each piezoelectric plate can independently detect pressure changes in its location. By analyzing which piezoelectric plate receives the greatest pressure, the primary direction of the wind can be determined. Comparing the pressure differences between the piezoelectric plates allows for further precision, and even detects changes in wind direction. Wind speed is estimated based on the relationship between the voltage generated by the piezoelectric plates and the wind pressure. During the system calibration phase, a quantitative relationship between pressure and voltage is established for real-time wind speed calculation. A digital signal processor converts the received voltage into wind speed values, relying on a previously established pressure-wind speed conversion model, either experimentally or theoretically.

[0066] In any of the above embodiments, the first detection part also includes a first detection ball 1 connected to the connecting rod 9, and the first sensor is installed inside the first detection ball 1; the first sensor is a sound sensor 101, and the sound sensor 101 is used to obtain noise data when the ocean wind flows through the first detection ball 1.

[0067] Noise data is used to generate the first wind speed data and correct the second wind speed data. The current wind force can be directly obtained from the sound level in the noise data and used as the first wind speed data. Because the swing amplitude of the connecting rod 9 under different forces does not show a cumulative relationship, or the swing amplitude after long-term use is different from the swing amplitude during initial use under the same wind force, this increases the cumulative measurement error. The noise data can be used to directly correct the second wind speed data detected by the swing of the connecting rod 9.

[0068] In this embodiment, the sound sensor 101 is used to capture noise data generated by ocean wind as it passes around the first detection sphere 1. This noise data may include the sound of wind blowing against the surface of the detection sphere, or the sound produced by wind impacting other objects in the area. By analyzing the characteristics of the captured sound (such as frequency, intensity, and duration), the wind speed and direction can be indirectly inferred.

[0069] The sound sensor 101 typically includes one or more microphone elements that convert sound waves into electrical signals. When sound waves strike the sound sensor 101, they cause physical vibrations in its internal components (such as a membrane or plate). These vibrations are then converted into electrical signals that represent the sound wave's characteristics, such as amplitude (volume), frequency (pitch), and waveform (texture or color). When wind flows over the first detection sphere 1, it produces specific sound patterns on the sphere's surface and in the surrounding space. These sound patterns vary depending on wind speed, direction, and stability. By accurately analyzing this noise data (using methods such as spectrum analysis and sound recognition technology), the system can identify specific wind characteristics.

[0070] Wind speed is directly estimated by analyzing the intensity of the sound produced when wind passes through the first detection ball 1. The sound intensity (amplitude) is proportional to wind speed and can therefore be used as a direct measurement of the first wind speed data. However, since the swing amplitude of the connecting rod 9 may change with long-term use or varying wind forces, directly using the swing of the connecting rod 9 to measure wind speed may introduce errors. Noise data provides an independent measurement method for verifying and calibrating the second wind speed data, reducing cumulative errors.

[0071] A sound sensor 101 is located inside the first detection sphere 1 to capture the sound produced by the passing wind. The greater the wind speed, the greater the force exerted on the first detection sphere 1, and the correspondingly greater the sound amplitude. The sound intensity (amplitude) is converted into an electrical signal by the sound sensor 101. This electrical signal is then quantified into a sound intensity value, which is used to estimate wind speed. The captured sound signal is amplified, filtered, and digitized, converting it into data that can be directly analyzed. A specific algorithm calculates the first wind speed data based on the sound intensity. This algorithm is based on a predefined relationship (a curve between sound intensity and wind speed) established during system calibration. The second wind speed data, measured by the swing amplitude of the connecting rod 9, may accumulate errors due to mechanical wear, external interference, or nonlinear response. By comparing the first wind speed data (sound measurement) with the second wind speed data (connecting rod 9 swing measurement), any inconsistencies can be identified and corrected. If there is a significant difference between the first and second wind speed data, the system can automatically adjust the calibration parameters to ensure the accuracy of the second wind speed data. This dual measurement method (sound and physical swing) allows the system to continuously optimize itself and adjust the measurement strategy and calibration standards through real-time feedback. In long-term operation, the system can automatically adapt to environmental changes and the impact of equipment aging through continuous data comparison and analysis, maintaining high accuracy and reliability of measurement data.

[0072] Specifically, the steps of adjusting the calibration parameters of the system include: Data comparison: Periodically or continuously, the first wind speed data (usually collected by a sensor that directly measures wind speed, such as an acoustic sensor) is compared with the second wind speed data (measured by the swing of the connecting rod and the piezoelectric piece).

[0073] Analyze the differences between the two to determine if there is a significant deviation.

[0074] Deviation threshold setting: Set an acceptable deviation threshold, such as 5%. When the deviation between the two sets of data exceeds this threshold, the calibration procedure is triggered. The threshold can be adjusted according to the specific application and accuracy requirements.

[0075] Automatic calibration is performed: If the deviation between the second wind speed data and the first wind speed data exceeds a threshold, the system automatically adjusts the calibration parameters. This may include modifying the sensor's sensitivity settings, the calibration algorithm, or dynamically adjusting the position of the piezoelectric piece relative to the connecting rod; Adjustment of calibration parameters is based on a preset calibration curve or the optimal solution obtained through a machine learning algorithm.

[0076] Feedback mechanism: After adjustment, the system collects data again and compares the new first wind speed data with the second wind speed data to verify the calibration effect; If the data still shows deviations, the system can further fine-tune calibration parameters or perform more in-depth diagnostics.

[0077] Record and learn: The system records the parameters and results of each calibration for future calibration process optimization; Leveraging historical data and results, machine learning techniques are employed to optimize the calibration process, making the system more intelligent and adaptive.

[0078] Furthermore, a through hole is opened on the top of the second detection ball 4 for the connecting rod 9 to pass through, and a bellows 2 is connected between the first detection ball 1 and the second detection ball 4. The bellows 2 covers the through hole and is sleeved on the part of the connecting rod 9 located outside the second detection ball 4. The bellows 2 is made of flexible material.

[0079] As can be seen from the above, the bellows 2 covers the connecting rod 9, protecting the connecting rod 9 from direct exposure to the marine environment, such as salt water corrosion, marine organism attachment or mechanical damage; the flexible material of the bellows 2 allows the connecting rod 9 to move freely without restriction under the action of wind, while maintaining good sealing to prevent moisture and impurities from entering the interior of the detection ball; the bellows 2 can absorb part of the impact and vibration caused by wind or waves, reducing the impact of these external forces directly acting on the connecting rod 9 and the detection ball.

[0080] When the connecting rod 9 passes through the top hole of the second detection sphere 4, the bellows 2 covers the hole and extends to the outside of the connecting rod 9. This configuration forms a continuous protective layer, preventing seawater and impurities from directly contacting the connecting rod 9 and the hole. The flexible structure of the bellows 2 allows the connecting rod 9 to undergo necessary movement under wind forces, such as bending or slight displacement, without excessive physical constraints. The corrugated design provides a high degree of flexibility, allowing the tube to withstand the movement of the connecting rod 9 without breaking. This design also maintains a good seal, preventing water and other external elements from penetrating the interior of the second detection sphere 4, which is crucial for maintaining the function of the second sensor inside. In addition, the bellows 2 can buffer the vibration caused by the swinging of the connecting rod 9, reducing the potential interference of such vibration with the detection equipment's accuracy. The bellows 2 is typically made of corrosion-resistant and high-strength plastic or rubber, which can withstand the harsh conditions of the marine environment, including UV radiation, salt spray, and extreme temperature fluctuations. By simplifying maintenance requirements and extending the system's service life, the bellows 2 improves the reliability and cost-effectiveness of the overall equipment.

[0081] In any of the above embodiments, all the piezoelectric sheets are connected to the inner wall of the inner groove through a support portion to ensure that each swing of the connecting rod 9 can be measured by the piezoelectric sheets at the same height, and the connecting rod 9 is connected to the inner wall of the inner groove through an elastic portion, and the bendable and deformable portion is realized through the elastic portion at the bottom, which can avoid the connecting rod 9 from being deflected during the swing and ensure that the rod body can be straightened when force is applied to the piezoelectric sheet.

[0082] The supporting portion includes a connecting ring 10 fixedly assembled with the piezoelectric sheet, and the connecting ring 10 is located between the piezoelectric sheet and the elastic portion, thereby preventing the deformation of the elastic portion from interfering with the pressure measurement of the piezoelectric sheet.

[0083] In this embodiment, all the piezoelectric sheets are connected to the inner wall of the inner groove through the support part, ensuring that no matter how the connecting rod 9 swings, the piezoelectric sheets are always at the same height, thereby ensuring the consistency of each measurement; the connecting rod 9 is connected to the inner wall of the inner groove through the elastic part. This elastic part allows the connecting rod 9 to deform flexibly when subjected to wind force, while preventing the connecting rod 9 from deflecting or twisting during swinging, ensuring that the connecting rod 9 can remain upright when force is applied to the piezoelectric sheets.

[0084] The support portion secures all piezoelectric elements in a specific position within the inner groove. This securement ensures that, regardless of how the connecting rod 9 moves or oscillates, all piezoelectric elements receive pressure applied by the connecting rod 9 at the same height. This consistent positioning is crucial for measurement accuracy, as it eliminates measurement deviations caused by varying piezoelectric element positions. The elastic portion is typically made of silicone, rubber, or other flexible materials that provide sufficient elasticity without disrupting connectivity. When the connecting rod 9 is subjected to external forces, this elastic portion deforms appropriately, absorbing some of the force and reducing the direct pressure on the piezoelectric elements. The design of the elastic portion not only protects the piezoelectric elements from damage caused by excessive pressure but also ensures that the connecting rod 9 is properly aligned when force is applied, avoiding measurement errors caused by deflection of the connecting rod 9. This structural design ensures that the system maintains high stability and responsiveness even in strong winds. The piezoelectric elements can accurately measure pressure changes caused by wind, and these measurements reflect the actual characteristics of the wind. Furthermore, the use of the elastic portion helps extend the life of the device by reducing mechanical wear and stress concentration.

[0085] The connecting ring 10 acts as a structural isolation component, shielding the piezoelectric element from direct mechanical interference caused by deformation of the elastic portion. This ensures that the piezoelectric element only measures wind-related pressure changes applied by the connecting rod 9. The connecting ring 10 securely supports the piezoelectric element, maintaining its stability while allowing it to accurately respond to the pressure from the connecting rod 9.

[0086] The connecting ring 10 securely holds the piezoelectric element in its designed position, preventing it from shifting or misaligning due to movement of other system components (such as deformation of the elastic element). This securement ensures consistent position and orientation of the piezoelectric element, which is crucial for ensuring repeatable and reliable measurements. When the connecting rod 9 oscillates under wind force, the elastic element may deform. Without the isolation provided by the connecting ring 10, this deformation could be directly transmitted to the piezoelectric element, resulting in erroneous pressure readings. The connecting ring 10 effectively prevents this interference, ensuring that the piezoelectric element only responds to pressure changes directly caused by wind force. The design and material selection of the connecting ring 10 are generally intended to optimize the force transmission path. The connecting ring 10 transmits the pressure received from the connecting rod 9 to the piezoelectric element in the most direct and uninterrupted manner, minimizing signal loss and errors caused by deformation. The connecting ring 10 not only provides structural support but also plays a critical role in the responsiveness and sensitivity of the entire detection system. By maintaining the piezoelectric element in its optimal position and condition, the connecting ring 10 helps the system respond quickly and accurately to changes in wind force in the environment.

[0087] In any of the above embodiments, the support portion also includes a plurality of support rods 11 for connecting the connecting ring 10 and the inner groove; all support rods 11 are retractably arranged so that the piezoelectric piece can correspond to the connecting rod 9 at different axial heights along the connecting rod 9, thereby achieving a change in the torque of the wind on the piezoelectric piece within different ocean wind force ranges, and at least one support rod 11 is an electric telescopic rod, which adjusts the corresponding axial position of the annular cavity and the connecting rod 9 by extending the length, so as to perform automatic adaptation within different wind force ranges.

[0088] In this embodiment, the retractable design of the support rod 11 allows the piezoelectric sheet to move to different heights along the axial direction of the connecting rod 9, so that the position of the piezoelectric sheet relative to the connecting rod 9 can be adjusted according to different wind conditions; the electric telescopic rod can automatically adjust its extension length according to the wind speed data to change the position of the piezoelectric sheet to adapt to different wind force ranges; by changing the height of the piezoelectric sheet, the torque applied by the wind on the piezoelectric sheet can be adjusted, which helps to optimize the sensing efficiency and measurement accuracy of the piezoelectric sheet.

[0089] The data processing unit is located inside the controller 6, which receives data from the wind speed sensor and calculates the ideal position of the piezoelectric piece based on this data. Depending on the strength of the wind, the controller 6 will instruct the electric telescopic rod to adjust its length, thereby raising or lowering the position of the piezoelectric piece. The adjustment process of the electric telescopic rod is automatic, ensuring that the piezoelectric piece is always in the best position to respond to the current wind conditions; all support rods 11, including the electric telescopic rod, work together to ensure that the piezoelectric piece can be accurately positioned along the axis of the connecting rod 9. These support rods 11 not only support the piezoelectric piece, but also ensure that it remains stable under the action of wind. The design of the retractable support rods 11 allows the system to dynamically adjust the height of the piezoelectric piece to adapt to the torque changes caused by different wind speeds; the piezoelectric piece will experience different torques at different heights of the connecting rod 9, which affects its ability to generate electrical signals. By precisely controlling the position of the piezoelectric plate, the system can optimize the torque and ensure that each wind action is effectively converted into a measurable electrical signal. This fine adjustment function enables the system to more accurately measure wind speed and direction, reducing errors caused by improper positioning. By automatically adjusting the height of the piezoelectric plate, the system can quickly adapt to changes in the environment and provide real-time and accurate wind data. This design increases the reliability and effectiveness of the system in complex marine environments and reduces the need for manual adjustment and maintenance costs.

[0090] In any of the above embodiments, the ocean wind speed and direction sensor mechanism further includes a controller 6, and the controller 6 is installed on the inner wall of the inner groove.

[0091] The controller 6 is connected to the first sensor and the electric telescopic rod, respectively, to adjust the extension length of the electric telescopic rod based on the first wind speed data. By correcting the extension length of the electric telescopic rod based on the first wind speed data detected during non-oscillation, the axial height of the piezoelectric plate relative to the connecting rod 9 can be adjusted automatically, eliminating the need for manual intervention.

[0092] In this embodiment, controller 6 receives wind speed data from the first sensor (sound sensor 101). This data provides direct information about the current wind speed, providing basic data for the control system. Based on the received wind speed data, controller 6 automatically adjusts the extension length of the electric telescopic rod to change the axial height of the piezoelectric plate relative to the connecting rod 9, thereby adapting to winds of varying strengths. By precisely adjusting the position of the piezoelectric plate, controller 6 ensures that the measurement equipment measures wind speed at the optimal height, improving data accuracy and system response speed.

[0093] The microprocessor within controller 6 analyzes wind speed data received from the first sensor. Based on this data, controller 6 calculates the ideal height of the piezoelectric disc for most accurate wind measurement. Using a pre-set algorithm or model, controller 6 dynamically adjusts the length of the motorized telescopic rod to change the axial position of the piezoelectric disc based on changes in wind speed. The motorized telescopic rod receives commands from controller 6 and adjusts its length accordingly. This length adjustment directly affects the position of the piezoelectric disc, moving it to the optimal measurement position for the current wind speed. This automatic adjustment mechanism eliminates the need for manual repositioning, enabling the system to respond quickly and accurately to environmental changes. The control system is designed to monitor and respond to changing environmental conditions in real time, ensuring maximum measurement efficiency and accuracy under any given wind condition. By adjusting the height of the piezoelectric disc, the system maximizes the impact of wind forces on the disc and reduces measurement errors caused by improper positioning. The automatic adjustment function of controller 6 reduces the system's reliance on external intervention, enhancing the device's availability and reliability in harsh or unpredictable marine environments. This automated capability not only improves operational efficiency but also reduces the complexity and cost of long-term maintenance and operation.

[0094] Furthermore, the controller 6 includes a battery 601 arranged axially along the connecting rod 9. The battery 601 is installed on the inner wall of the inner groove and is used to supply power to the controller 6, the first sensor, the second sensor and the electric push rod.

[0095] As can be seen from the above, the battery 601 provides the necessary power for the controller 6 and its connected sensors and electric telescopic rods, ensuring that the system can operate normally even without an external power supply; through the built-in battery 601, the system can operate independently in remote marine environments without being restricted by power supply, thereby improving the application range and flexibility of the system; in the process of continuous monitoring and data recording, an uninterrupted power supply is indispensable, and the battery 601 ensures the continuity of data acquisition and processing, avoiding data loss.

[0096] Battery 601 stores energy through electrochemical reactions. When system components, such as sensors or the telescopic pole, require power, battery 601 provides the required power through circuits. Controller 6 typically includes a battery management system (BMS), which monitors the battery's charge status, voltage, temperature, and other parameters to ensure safe and optimal operation. Controller 6 distributes power from battery 601 based on the power needs of each component. For example, when the telescopic pole needs to adjust its position to accommodate wind speed fluctuations, controller 6 instructs battery 601 to provide power. Controller 6 is also responsible for reducing power consumption when the system is idle, such as by switching sensors to low-power mode to extend battery life. When an external power source is available (such as charging from a solar panel), controller 6 manages the charging process for battery 601, ensuring efficient charging and maintaining a healthy state of battery health. Controller 6 also monitors battery performance and, if it detects a decrease in battery capacity or other performance issues, can make necessary adjustments or issue maintenance warnings.

[0097] Furthermore, the controller 6 also includes a charging plate 602 installed on the top of the first detection ball 1, and the charging plate 602 is a solar charging plate.

[0098] As can be seen from the above, the charging panel 602 charges the battery 601 by capturing sunlight and converting it into electrical energy, ensuring that the system can continue to operate even in remote marine environments or where it is inconvenient to access conventional power sources; using solar energy as an energy source reduces dependence on fossil fuels and improves the environmental friendliness and sustainability of the system; because the charging panel 602 provides a reliable energy supply method, the system's maintenance requirements are reduced because there is no need to frequently replace batteries or perform other energy supply operations.

[0099] The charging panel 602 is composed of multiple photovoltaic cells, typically made of silicon-based materials such as monocrystalline or polycrystalline silicon. These photovoltaic cells convert sunlight into electricity through a process known as the photovoltaic effect. When sunlight strikes the charging panel 602, electrons within the photovoltaic cells are excited and flow, generating an electric current. This current is then collected and transmitted through circuitry to the battery 601 for storage. The controller 6 includes a battery management system (BMS), which monitors the power received from the charging panel 602 and safely and efficiently stores it in the battery 601. The BMS regulates the charging process to prevent overcharging and over-discharging, protecting the battery's health and extending its lifespan. It also ensures that power can be drawn from the battery 601 when needed to supply other system components. The controller 6 automatically adjusts the charging strategy based on environmental conditions (such as light intensity) and system requirements to optimize energy utilization. When sunlight is sufficient, the controller 6 prioritizes solar charging to meet the system's immediate power needs. When sunlight is insufficient, the controller manages the power provided by the battery 601 to ensure continuous system operation.

[0100] In any of the above embodiments, the elastic part is a junction box 902, which is hollow and has a bypass hole on the side for the power supply line to pass through. The connecting rod 9 has a connecting hole 901 axially opened, and the connecting hole 901 connects the inner cavity of the junction box 902 and the inner cavity of the first detection ball 1 to obtain the first wind speed data of the first sensor and to connect and power the first sensor.

[0101] In this embodiment, the junction box 902 houses electrical connections and wiring through its hollow design, protecting these sensitive components from the influence of the external environment (such as seawater, moisture, corrosion, etc.); the wires in the junction box 902 enter and exit through bypass holes, which not only provide a clear path for the wires, but also reduce the risk of mechanical damage to the wires; the junction box 902 simplifies and protects the wire connection from the first sensor to the controller 6, ensuring the stability of power supply and data transmission.

[0102] The interior of the junction box 902 communicates with the connecting rod 9 and the inner cavity of the first detection ball 1 through a connection hole 901. This arrangement allows wires from sensors (such as the acoustic sensor 101) in the first detection ball 1 to be safely routed through the connecting rod 9 and transmitted to other components of the system, such as the battery 601 and the controller 6. The space within the junction box 902 provides adequate physical protection for the wires, preventing damage from external physical forces (such as vibration or vibration). Wires enter and exit the junction box 902 through side bypass holes. These bypass holes are designed to be large enough to accommodate multiple wires while being tight enough to prevent the ingress of water and moisture. These holes are also designed with waterproof seals, enhancing the durability and reliability of the entire system in marine environments. The junction box 902 not only provides physical protection but also ensures clear and interference-free transmission of electrical signals and power. The orderly organization of the wires reduces the possibility of electromagnetic interference and signal loss. Furthermore, the design of the junction box 902 generally considers electrical safety, including short-circuit protection and easily maintainable interfaces.

[0103] Furthermore, the junction box 902 is made of rubber, so that when the ocean wind drives the first detection ball 1 and the connecting rod 9, one end of the connecting rod 9 can move circumferentially around the other end and realize the swing of the connecting rod 9.

[0104] As can be seen from the above, the rubber material gives the junction box 902 good elasticity and flexibility, allowing the connecting rod 9 to swing naturally under the action of wind while maintaining the integrity and safety of the wire connection; rubber has excellent waterproof properties and can effectively block seawater and moisture to prevent them from corroding wires and electrical components, making it particularly suitable for marine environments; the rubber junction box 902 can absorb and cushion the impact caused by the swinging of the connecting rod 9, protecting the internal wires from excessive stretching or compression.

[0105] The elasticity of the rubber material allows the junction box 902 to physically withstand the swinging and twisting of the connecting rod 9 without breaking or permanently deforming. This elasticity also allows the junction box 902 to conform to the movement of the connecting rod 9 as it swings, reducing the mechanical stress on the wires. When the first detection ball 1 moves under the influence of the wind, the junction box 902 allows the connecting rod 9 to rotate or bend limitedly around its fixed point without affecting the structural integrity of the wires. The rubber material is naturally waterproof, and the design of the junction box 902 includes seals for the interfaces and through-holes to prevent moisture from entering. This is particularly critical for marine applications, as seawater can quickly corrode and damage electrical systems. The sealed design of the junction box 902 also prevents the intrusion of salt and other corrosive substances, extending the service life of the equipment. The rubber material of the junction box 902 can absorb some of the vibration and impact force generated by the swinging of the connecting rod 9, helping to protect the internal wires and electrical components from damage.
