[0042] This disclosure provides a marine photovoltaic support system with condition monitoring capabilities, such as... Figures 1-5As shown, the system includes a photovoltaic support 300, a data acquisition module 11, and an image acquisition module. The photovoltaic support 300 includes a photovoltaic panel base 330, a mounting frame, and multiple piles 310. One end of each pile 310 is fixed in the sea, and the other end extends above the sea surface. The mounting frame is fixedly installed via the multiple piles 310. The mounting frame includes multiple vertical supports 323, horizontal supports 321, and connecting rods 322. The vertical supports 323 are fixedly connected to the piles 310, and the horizontal supports 321 and connecting rods 322 are fixedly installed via the vertical supports 323. The horizontal supports 321 and connecting rods 322 are connected to form an installation part for installing the photovoltaic panel 400. The data acquisition module 11 is mounted on the photovoltaic support 300 and includes multiple tilt sensors 110 configured to acquire tilt information of the photovoltaic support 300. The image acquisition module is mounted on the photovoltaic support 300 and includes a camera 140 configured to acquire image information of the photovoltaic support 300.

[0043] The offshore photovoltaic (PV) support structure with condition monitoring provided in this disclosure includes a data acquisition module 11 and an image acquisition module on the PV support 300. The tilt sensor 110 in the data acquisition module 11 can acquire the tilt angle information of the PV support 300 in real time. By monitoring the tilt angle, it is possible to promptly detect tilting deformation of the PV support 300 caused by wind and wave impact, foundation settlement, etc., providing key data for assessing the stability of the PV support 300. The camera 140 of the image acquisition module acquires image information of the PV support 300, intuitively displaying the appearance status of the PV support 300, which facilitates maintenance personnel to quickly identify whether there are any visible abnormalities such as structural damage or loose parts. The two monitoring methods complement each other, realizing the preliminary monitoring of the condition of the PV support 300.

[0044] Specifically, the photovoltaic support 300 is fixed to the pile foundation 310, one end of which is located below the sea surface, and the other end extends above the sea surface to secure the photovoltaic support 300. Multiple pile foundations 310 can be arrayed on the sea surface to form a stable support for the photovoltaic support 300. The photovoltaic panel 400 is mounted on the photovoltaic support 300, for example, fixed to the photovoltaic panel base 330 of the photovoltaic support 300.

[0045] In one embodiment, the data acquisition module 11 further includes multiple vibration sensors 120, which are configured to acquire vibration information of the photovoltaic support 300. The continuous action of sea waves causes the photovoltaic support 300 to vibrate. The vibration sensors 120 can monitor the vibration information of the support in real time, including parameters such as vibration frequency and amplitude. By analyzing this vibration data, the stress state of the support under the action of sea waves can be determined, and abnormal vibrations can be detected in a timely manner. Abnormal vibrations often indicate potential problems such as loosening or damage to the support structure. Early detection of this information helps maintenance personnel take measures to reinforce or repair the structure, preventing further deterioration of the photovoltaic support 300's faults and ensuring the safe and stable operation of the photovoltaic power station.

[0046] In one embodiment, the data acquisition module 11 further includes multiple corrosion sensors 130, which are configured to acquire corrosion information of the photovoltaic support 300. The high salinity of seawater and humid air can cause corrosion of the metal materials of the photovoltaic support 300, affecting its structural strength and service life. The corrosion sensors 130 can acquire corrosion information of the support in real time, such as corrosion rate and degree of corrosion. By monitoring and analyzing this data, the corrosion status of the photovoltaic support 300 can be grasped in a timely manner, and the corrosion development trend can be predicted, providing a scientific basis for formulating a reasonable anti-corrosion maintenance plan. Taking effective anti-corrosion measures before the corrosion becomes severe, such as recoating the anti-corrosion coating or replacing corroded parts, can extend the service life of the photovoltaic support 300, reduce the risk of damage to the photovoltaic support 300 due to corrosion, and ensure the long-term stable operation of the photovoltaic power station.

[0047] Multiple tilt sensors 110, vibration sensors 120, and corrosion sensors 130 can be distributed on the horizontal support rods 321, connecting rods 322, vertical support rods 323 of the photovoltaic support 300, as well as the end connectors 340 of the photovoltaic panel base 330 and the pile foundation 310 to form a monitoring network. The end connectors 340 of the pile foundation 310 can be pre-embedded connectors at the end of the pile foundation 310 to be fixedly connected to the vertical support rods 323 of the photovoltaic support 300, thereby achieving a fixed connection between the pile foundation 310 and the photovoltaic support 300.

[0048] A tilt sensor 110 is installed on the horizontal support rod 321, horizontally positioned to obtain the horizontal tilt angle of the horizontal support rod 321. A tilt sensor 110 is also installed on the vertical support rod 323, vertically positioned to obtain the vertical tilt angle of the vertical support rod 323. By installing the tilt sensor 110 horizontally on the horizontal support rod 321 and the tilt sensor 110 vertically on the vertical support rod 323 to obtain the vertical tilt angle, the tilt changes of the horizontal support rod 321 and the vertical support rod 323 in different directions can be accurately monitored, providing a comprehensive understanding of the tilt state of the photovoltaic support 300.

[0049] Specifically, such as Figure 4 As shown, the photovoltaic support 300 may also be equipped with a data processing module 12 and a fault diagnosis and early warning module 13. The data processing module 12 is connected to the data acquisition module 11. The data processing module 12 is configured to receive tilt angle information, vibration information and corrosion information acquired from the data acquisition module 11, and determine the attitude data of the photovoltaic support 300 through the tilt angle information, the vibration data of the photovoltaic support 300 through the vibration information, and the corrosion data of the photovoltaic support 300 through the corrosion information. The fault diagnosis and early warning module 13 is connected to the data processing module 12. The fault diagnosis and early warning module 13 is configured to receive the attitude data of the tilt angle of the photovoltaic support 300, vibration data and corrosion data determined by the data processing module 12, and determine whether there is abnormal data in the attitude data, vibration data and corrosion data; if there is abnormal data, an early warning signal is output.

[0050] Specifically, if abnormal data is detected, a corresponding early warning signal is output, making the early warning system more accurate and targeted. When the system detects an anomaly, it does not simply issue a uniform alarm, but rather outputs specific early warning signals based on different types of abnormal data, such as abnormal tilt angle, abnormal vibration, or abnormal corrosion. Maintenance personnel can quickly determine the nature and possible causes of the fault based on the type of early warning signal, and take targeted maintenance and handling measures, improving the efficiency of fault handling and reducing unnecessary waste of manpower and resources.

[0051] Specifically, when attitude data, vibration data, or corrosion data are missing or exceed preset value ranges, data anomalies are identified. This provides a clear standard and basis for the system to determine whether data is abnormal. Data loss may be due to sensor malfunctions, communication line interruptions, etc. Timely detection of data loss helps maintenance personnel quickly locate and repair problems, ensuring the integrity of data collection. Data exceeding preset value ranges directly reflects abnormalities in the operating status of the photovoltaic support 300. By setting reasonable value ranges, abnormal changes in the photovoltaic support 300 under the influence of factors such as wind, waves, and corrosion can be accurately captured, providing a reliable basis for fault diagnosis and early warning.

[0052] One approach is to use a dynamic threshold adjustment method, which automatically adjusts the preset value range based on factors such as sea conditions, season, and operating time. For example, during typhoon season, due to larger waves, the threshold range for tilt angle and vibration data can be appropriately widened; during the initial operation of the photovoltaic support 300, due to the material break-in period, the threshold for corrosion data can be specially processed to better reflect actual operating conditions.

[0053] The attitude data includes the trend, magnitude, and frequency of the tilt angle change of the photovoltaic support 300. The tilt angle change trend reflects the direction of the tilt change of the photovoltaic support 300 over a period of time, helping maintenance personnel to determine whether the photovoltaic support 300 is gradually tilting, so as to take reinforcement measures in advance; the magnitude of the change reflects the magnitude of the tilt angle change of the photovoltaic support 300, which can promptly detect severe tilting of the photovoltaic support 300 under the influence of factors such as wind and waves; the frequency of change reflects the frequency of external excitation of the photovoltaic support 300, which helps to analyze the sea environment and stress conditions in which the photovoltaic support 300 is located, providing comprehensive information for accurately judging the attitude status of the photovoltaic support 300 and predicting potential failures.

[0054] The vibration data includes the vibration amplitude and frequency of the photovoltaic support structure 300. Vibration amplitude reflects the severity of vibration when the support structure is subjected to external excitation (such as wind and wave impact). Large vibration amplitudes can lead to structural fatigue, loosening of connectors, and other problems, directly affecting the stability and service life of the support structure. Vibration frequency is closely related to the natural frequency of the support structure. When the external excitation frequency approaches the natural frequency, resonance can easily occur, causing serious damage to the support structure. Monitoring the vibration amplitude and frequency allows for the timely detection of abnormal vibrations during operation, providing crucial information for fault diagnosis and prevention.

[0055] The corrosion data includes the corrosion rate of the photovoltaic support structure 300. The corrosion rate is a key indicator for measuring the degree of corrosion of the photovoltaic support structure 300 in the high-salinity, humid marine environment. By monitoring the corrosion rate, the corrosion status of the support structure can be understood in a timely manner, the remaining service life of the support structure can be predicted, and a basis for formulating a reasonable anti-corrosion maintenance plan can be provided. When the corrosion rate exceeds a certain threshold, it indicates that the corrosion of the support structure is relatively severe, and anti-corrosion measures need to be taken in a timely manner, such as recoating the anti-corrosion coating and replacing corroded components, to prevent the structural strength of the support structure from decreasing due to corrosion, thus affecting the safe operation of the power generation system.

[0056] Among them, a high-precision MEMS (Micro-Electro-Mechanical Systems) tilt sensor 110, combined with a multi-axis design, can more comprehensively monitor the tilt changes of the photovoltaic support 300 in different directions, improving the accuracy and reliability of tilt information acquisition. Meanwhile, sensors are rationally distributed in key parts of the photovoltaic support 300, such as support joints and support rods.

[0057] The vibration sensor 120 can be a piezoelectric vibration sensor with wide frequency response characteristics, which can effectively capture various vibration signals from low frequency to high frequency and adapt to the complex and ever-changing wind and wave frequencies at sea. In addition, in order to improve the anti-interference capability of the vibration sensor 120, shielding technology and filtering circuits can be used to reduce the impact of electromagnetic interference on vibration signal acquisition.

[0058] Among them, the corrosion sensor 130 can be a corrosion monitoring sensor based on the principle of electrochemistry, which can accurately calculate the corrosion rate of the photovoltaic bracket 300 by measuring the change of current or potential between electrodes in real time.

[0059] Specifically, such as Figure 5 As shown, the automated monitoring system also includes a demodulation substation 230, a fiber optic ring network 220, a switch, and a monitoring host 210. The demodulation substation 230 includes a tilt decoder, a vibration decoder, and a corrosion decoder. The tilt decoder is connected to the tilt sensor 110, the vibration decoder is connected to the vibration sensor 120, and the corrosion decoder is connected to the corrosion sensor 130. The tilt decoder, vibration decoder, and corrosion decoder are connected to the switch through the fiber optic ring network 220. The switch is connected to the monitoring host 210 through the fiber optic ring network 220 to upload the data interpreted by the tilt decoder, vibration decoder, and corrosion decoder to the monitoring host 210. The monitoring host 210 can determine the attitude data, vibration data, and corrosion data of the photovoltaic support 300 based on the data interpreted by the tilt decoder, vibration decoder, and corrosion decoder.

[0060] The tilt decoder, vibration decoder, and corrosion decoder in demodulation substation 230 are connected to their respective sensors to decode and process the data collected by the sensors. The decoded data is uploaded to the monitoring host 210 via a data transmission network composed of fiber optic ring network 220 and a switch, ensuring the stability and accuracy of data transmission. Based on the received data, the monitoring host 210 determines the attitude, vibration, and corrosion data of the photovoltaic support 300, forming a complete data acquisition, transmission, and processing link. This architecture not only ensures reliable data transmission in complex marine environments but also provides the hardware foundation for centralized monitoring and management of the system, facilitating real-time monitoring of the photovoltaic support 300's operating status by maintenance personnel.

[0061] The tilt angle data is decoded and uploaded to the monitoring host 210. The monitoring host 210 is configured to perform data cleaning and filtering on the data interpreted by the tilt angle decoder, and then determine the attitude data of the photovoltaic support 300. The marine environment is complex and variable, and the data collected by sensors is easily affected by noise, resulting in inaccurate and incomplete data. Data cleaning removes duplicate, erroneous, or invalid data; filtering removes noise signals and improves data quality. The processed data more accurately reflects the actual tilt state of the support, thus ensuring the reliability of the determined attitude data. This provides a precise basis for subsequent fault diagnosis and early warning based on attitude data, improving the accuracy and reliability of the entire monitoring system.

[0062] The corrosion data includes the corrosion rate. Periodic corrosion data is acquired by corrosion sensor 130. The monitoring host 210 determines the current corrosion rate based on this data, and the fault diagnosis and early warning module 13 compares the current corrosion rate with a standard corrosion rate. The corrosion sensor 130 acquires periodic corrosion data, and the monitoring host 210 calculates and analyzes this data to determine the current corrosion rate. By comparing the current corrosion rate with a standard corrosion rate, the corrosion status of the photovoltaic support 300 can be promptly assessed, and its remaining service life can be predicted, providing a scientific basis for developing a reasonable anti-corrosion maintenance plan. When the corrosion rate exceeds the standard value, an early warning is issued, prompting maintenance personnel to take anti-corrosion measures to prevent the structural strength of the photovoltaic support 300 from decreasing due to corrosion, thus ensuring the safe and stable operation of the offshore photovoltaic power station. For example, real-time monitoring data can be transmitted to the data acquisition unit via a 4mA to 20mA control signal, and then transmitted to the computer. The decoder and the monitoring host 210 work together to test the uniform and local corrosion of different materials in seawater corrosive media in real time. The data is updated every 7 minutes, and the operator can compare the previous corrosion rate with the current corrosion rate.

[0063] The system can establish a dynamic adjustment model for the standard corrosion rate based on various marine environmental parameters (such as salinity, humidity, and temperature), the material characteristics of the photovoltaic support 300, and operating time. For example, in high-salinity sea areas or during hot and humid seasons, the standard corrosion rate threshold can be appropriately lowered to increase sensitivity to corrosion. Furthermore, when an abnormal corrosion rate is detected, not only is an early warning signal issued, but a detailed corrosion cause analysis report is also provided. This report analyzes environmental data and historical corrosion data to determine whether the cause is environmental factors or the failure of the photovoltaic support 300's own anti-corrosion measures, providing a reference for maintenance personnel to develop targeted anti-corrosion maintenance plans.

[0064] In one embodiment, the photovoltaic support 300 is also equipped with a communication module, which is connected to the monitoring host 210. The communication module is configured to send monitoring information acquired by the monitoring host 210. The communication module enables remote transmission of monitoring information, allowing maintenance personnel to obtain real-time operating status information of the photovoltaic support 300 through mobile phones, computers, and other terminal devices without going to the site, facilitating remote monitoring and management.

[0065] The communication module can use 4G / 5G mobile communication technology to achieve high-speed data transmission, meeting the needs of rapid uploading and downloading of real-time monitoring data; at the same time, it is equipped with a satellite communication module as a backup communication method, so that reliable transmission of monitoring information can be ensured through satellite communication when mobile communication signal coverage is insufficient or malfunctions occur at sea.

[0066] In one embodiment, the image acquisition module includes multiple cameras 140, which acquire image information from different areas of the photovoltaic support 300. The arrangement of multiple cameras 140 enables comprehensive, multi-angle monitoring of the photovoltaic support 300, eliminating blind spots in image monitoring. Cameras 140 in different areas can focus on key parts of the support, such as the connection points of the photovoltaic panels 400, welded joints, and the portion of the pile foundation 310 above the water surface, enabling timely detection of abnormalities such as damage, deformation, and corrosion in these areas. By reviewing images captured by different cameras 140, maintenance personnel can gain a comprehensive understanding of the photovoltaic support 300's status, quickly locate faults, and improve the efficiency and accuracy of fault diagnosis.

[0067] In addition to basic functions such as high definition, night vision, and wide-angle, the camera 140 can also be equipped with intelligent analysis capabilities, such as a smart camera 140 with target recognition and behavior analysis functions. This smart camera 140 can automatically identify abnormal targets in images, such as detached parts or cracks, and analyze the target's behavior, such as the movement trajectory of parts, further improving the intelligence level of fault detection. Furthermore, the camera 140 is equipped with a waterproof, dustproof, and salt spray-proof protective shell to ensure its normal operation in harsh marine environments.

[0068] In one embodiment, the offshore photovoltaic support 300 also includes a power module, which is mounted on the photovoltaic support 300 and connected to the data acquisition module 11 and the image acquisition module. The power module provides power to the data acquisition module 11 and the image acquisition module, ensuring the continuous and stable operation of each monitoring module. In the marine environment, the stability of the power supply is crucial. The power module ensures that sensors, cameras, and other equipment can operate normally under various conditions, preventing data loss due to power outages, guaranteeing the continuity and reliability of the monitoring system, and providing a fundamental guarantee for real-time monitoring of the photovoltaic support 300's status.

[0069] The power module utilizes photovoltaic power generation to supply electricity to the system, making full use of the abundant solar energy resources at sea to achieve green and sustainable power supply. Simultaneously, it is equipped with batteries as a backup power source, automatically switching power supply when sunlight is insufficient or solar power fails, ensuring uninterrupted system operation.
