Description

Technical Field

[0001] This invention relates to the fields of marine engineering and underwater power transmission technology, specifically to a biomimetic coupling system and method for preventing and eliminating marine organisms using underwater wireless power supply equipment. Background Technology

[0002] Biofouling, the attachment and growth of marine organisms on the surfaces of artificial facilities, is a common problem faced by various underwater devices that are submerged in seawater for extended periods. For underwater wireless power supply equipment, biofouling not only increases additional structural load and fluid resistance, threatening equipment safety and stability, but also covers the outer shell, interferes with heat dissipation, and may affect electromagnetic field distribution, thereby reducing energy transmission efficiency and reliability. Furthermore, the biofouling layer can easily induce localized corrosion, posing significant difficulties and costs to underwater inspection and maintenance operations.

[0003] Currently, antifouling technologies for underwater structures mainly include antifouling coatings, electrolytic seawater antifouling, and physical-mechanical cleaning methods. However, traditional antifouling coatings often contain heavy metals, posing environmental risks and having limited shelf life; continuous electrolytic antifouling consumes a lot of energy and may produce harmful byproducts; while simple physical cleaning can only serve as a remedial measure, failing to achieve effective prevention and incurring high operating costs. Existing single technologies often struggle to balance long-term antifouling effectiveness, environmental compatibility, operational economy, and non-interference with the electromagnetic performance of wireless power supply systems.

[0004] Therefore, there is an urgent need in this field for a comprehensive biofouling prevention and control solution that can coordinate multiple antifouling mechanisms, achieve intelligent control, combine high efficiency and environmental friendliness, and is particularly suitable for the specific scenario of underwater wireless power supply equipment. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a biomimetic coupling system and method for preventing and eliminating marine organisms using underwater wireless power supply equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] In a first aspect, this application provides a biomimetic coupling system for preventing and eliminating marine organisms using an underwater wireless power supply device, comprising:

[0008] A biomimetic microstructure antifouling layer is applied to the outer surface of the underwater wireless power supply device;

[0009] An electrolytic antifouling unit includes at least one anode and one cathode immersed in seawater, and a DC power supply electrically connected to the anode and cathode;

[0010] A central control unit, which is connected to the electrolytic antifouling unit;

[0011] The central control unit is configured to execute a dynamic control algorithm, which calculates a biofouling risk assessment value based on seawater environmental parameters collected by sensors, and dynamically adjusts the output current density and operating duty cycle of the electrolytic antifouling unit according to the biofouling risk assessment value.

[0012] Furthermore, the microstructure of the biomimetic microstructure antifouling layer is a periodically arranged rib-like structure, with the rib width being 10-200 micrometers, the height being 50-500 micrometers, and the spacing being 50-300 micrometers; the anode of the electrolytic antifouling unit is a titanium anode with a mixed metal oxide coating, and the cathode is titanium or stainless steel.

[0013] Furthermore, the seawater environmental parameters include at least one of temperature, salinity, and turbidity; the central control unit synthesizes the seawater environmental parameters into the bioattachment risk assessment value through a fusion calculation model.

[0014] Furthermore, the central control unit is further configured to execute a self-learning optimization algorithm, which dynamically optimizes the parameter weights in the fusion computing model based on the system's historical operating data and anti-fouling effect feedback.

[0015] Furthermore, it also includes a biofilm monitoring module, which detects the biofilm adhesion status on the surface of the biomimetic microstructure antifouling layer based on electrochemical impedance spectroscopy.

[0016] Furthermore, it also includes a mechanical cleaning module; the central control unit is configured to activate the mechanical cleaning module when the impedance value detected by the biofilm monitoring module exceeds a set threshold.

[0017] Furthermore, the set threshold is dynamically adjusted based on the cumulative running time of the system.

[0018] Furthermore, the underwater wireless power supply device is the transmitter or receiver of an underwater wireless energy transmission device, and the arrangement of the biomimetic microstructure antifouling layer and the electrolytic antifouling unit avoids the electromagnetic induction core area of ​​the device.

[0019] Secondly, this application provides a method for preventing the growth of marine organisms using the system described above, comprising the following steps:

[0020] The biomimetic microstructure antifouling layer is prepared on the outer surface of the underwater wireless power supply device;

[0021] The electrode pairs of the electrolytic antifouling unit are installed on the surface area of ​​the underwater wireless power supply device;

[0022] The central control unit runs the dynamic control algorithm to control the operating parameters of the electrolytic antifouling unit based on the real-time collected seawater environmental parameters.

[0023] Furthermore, it also includes the following steps:

[0024] The surface condition of the biomimetic microstructure antifouling layer is monitored using the biofilm monitoring module.

[0025] When monitoring data indicates the presence of biofilm, the central control unit triggers the mechanical cleaning module to perform cleaning.

[0026] Compared with the prior art, this application has the following beneficial effects:

[0027] This invention proposes a biomimetic coupling system and method for preventing and controlling marine organism fouling in underwater wireless power supply equipment. By setting a biomimetic microstructure antifouling layer, specific microscopic physical structures are constructed on the outer surface of the equipment, which can effectively interfere with the initial attachment of marine larvae, significantly reducing the accumulation of biofouling at the source. This directly reduces the additional structural load and safety risks caused by massive biofouling, while maintaining the fluid smoothness and cleanliness of the equipment surface, which helps maintain its hydrodynamic efficiency and heat dissipation performance, thereby ensuring the basic operational safety and energy transmission efficiency of the underwater wireless power supply equipment. By combining the electrolytic antifouling unit with the central control unit, a green chemical antifouling method is provided. The active substances (such as hypochlorous acid) generated by the electrolysis of seawater have environmentally friendly and residue-free characteristics. More importantly, the central control unit dynamically controls the operation of this unit based on environmental parameters, so that it only operates in a low current density, intermittent mode when necessary. This intelligent, on-demand supply model enables the entire system to maintain effective antifouling concentration with extremely low energy consumption, overcoming the drawbacks of high energy consumption in traditional continuous electrolysis methods and the potential environmental pollution caused by chemical antifouling coatings. Through a dynamic control algorithm integrated into the central control unit, the system can adaptively adjust its antifouling strategy based on actual environmental conditions (such as water temperature and salinity). This intelligent management not only optimizes the antifouling effect but also minimizes the ineffective consumption of energy and chemicals, achieving precise antifouling. Consequently, the system significantly extends the maintenance-free cycle of the equipment, reduces reliance on high-cost, high-risk underwater manual or mechanical cleaning operations, and substantially reduces the operation and maintenance costs of underwater wireless power supply equipment from a life-cycle perspective.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Furthermore, in this invention, an element referred to as fixed to or disposed on another element may be directly disposed on the other element, or there may be an intermediate element. When an element is considered to be connected to another element, it may be directly connected to the other element, or there may be an intermediate element present simultaneously. The terms vertical, horizontal, left, right, and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0032] See Figure 1 In a first aspect, this application provides a biomimetic coupling system for preventing and controlling marine organisms using underwater wireless power supply equipment, comprising:

[0033] A biomimetic microstructure antifouling layer is applied to the outer surface of the underwater wireless power supply device;

[0034] An electrolytic antifouling unit includes at least one anode and one cathode immersed in seawater, and a DC power supply electrically connected to the anode and cathode;

[0035] A central control unit, which is connected to the electrolytic antifouling unit;

[0036] The central control unit is configured to execute a dynamic control algorithm, which calculates a biofouling risk assessment value based on seawater environmental parameters collected by sensors, and dynamically adjusts the output current density and operating duty cycle of the electrolytic antifouling unit according to the biofouling risk assessment value.

[0037] This embodiment protects a biomimetic coupling system for preventing marine organisms using an underwater wireless power supply device. The underwater wireless power supply device clearly defines the application scope of this invention, encompassing the transmitter, receiver, and related facilities for underwater wireless energy transmission. This differs from general marine structures, emphasizing that the solution must balance antifouling functionality and electromagnetic compatibility. The biomimetic microstructure antifouling layer refers to a functional layer with a specific microstructure formed on the surface of the device through physical or chemical methods. Its core function is to passively resist biological attachment using biomimetic principles, forming the system's first physical barrier. The electrolytic antifouling unit includes electrodes and a power source. Its function is to actively generate and release antifouling agents through the green electrochemical process of seawater electrolysis, forming the second chemical barrier. The central control unit is the brain of the system. Its dynamic control algorithm is a set of software logic that can adjust the output commands (electrolysis parameters) in real time based on input information (environmental parameters). This algorithm upgrades the system from a static, passive antifouling mode to a dynamic, adaptive, intelligent antifouling mode.

[0038] The components work together: the biomimetic structure acts as a primary passive barrier to reduce most of the fouling; intelligent electrolysis acts as a secondary active barrier to remove any stray fouling as needed; condition monitoring and mechanical cleaning serve as a tertiary level of protection; the entire system pays special attention to electromagnetic compatibility, and the placement of all anti-fouling components avoids the electromagnetic induction core area of ​​the wireless power supply equipment.

[0039] In one specific embodiment, the microstructure of the biomimetic microstructure antifouling layer is a periodically arranged rib-like structure, wherein the rib width of the rib-like structure is 10-200 micrometers, the height is 50-500 micrometers, and the spacing is 50-300 micrometers; the anode of the electrolytic antifouling unit is a titanium anode with a mixed metal oxide coating, and the cathode is titanium or stainless steel.

[0040] In this embodiment, the specific morphology and size of the biomimetic microstructure are defined. The "periodically arranged rib-like structure" is an imitation of the surface features of organisms such as shark skin. The size range of "width 10-200 micrometers, height 50-500 micrometers, spacing 50-300 micrometers" is an effective range obtained through extensive biomimetic research and fluid dynamics simulation optimization. For example, ribs within this size range can effectively disrupt the laminar flow layer of water on the device surface, generating turbulence, making it difficult for marine larvae to "land" stably. At the same time, this size matches the attachment organ size of many fouling larvae, maximizing the difficulty of actual contact between the secreted adhesive substances and the substrate, thereby mechanically preventing their stable attachment. This limitation excludes other potentially ineffective or poorly performing random rough structures.

[0041] In one specific embodiment, the seawater environmental parameters include at least one of temperature, salinity, and turbidity; the central control unit synthesizes the seawater environmental parameters into the bioattachment risk assessment value through a fusion calculation model.

[0042] In this embodiment, the specific materials of the electrodes in the electrolysis antifouling unit are specified. The titanium anode with a mixed metal oxide coating (such as an IrO2-Ta2O5 coated titanium anode) is a preferred anode material for seawater electrolysis that has been proven in practice. It has extremely high electrocatalytic activity, excellent chemical stability, and an ultra-long service life, which can ensure that the electrolysis reaction proceeds efficiently and persistently. The cathode is titanium or stainless steel, which is a comprehensive choice based on cost, conductivity, and resistance to seawater corrosion. This limitation excludes ordinary and easily damaged electrode materials (such as graphite and ordinary steel), ensuring the long-term reliability of the core chemical barrier of the system.

[0043] In one specific implementation, the central control unit is further configured to execute a self-learning optimization algorithm, which dynamically optimizes the parameter weights in the fusion computing model based on the system's historical operating data and anti-fouling effect feedback.

[0044] In this embodiment, the intelligent decision-making basis of the central control unit is further clarified. The "seawater environmental parameters" include temperature, salinity, and turbidity because these are the most critical environmental factors affecting the metabolism of marine organisms and the planktonic and attachment behavior of larvae; for example, water temperature directly determines the activity of biological enzymes, and most fouling organisms are more active in summer (high temperatures); the fusion calculation model refers to a mathematical method that integrates multiple environmental parameters into a single risk assessment value; a basic and effective implementation method is a linear weighted model: ;in, The calculated bioattachment risk assessment value (dimensionless), , , These are the normalized measurements of temperature, salinity, and turbidity. , , These are the weighting coefficients for each parameter. The central control unit calculates these values ​​in real time. By dynamically adjusting the electrolysis parameters, the antifouling strength and the degree of environmental threat are precisely matched.

[0045] Specifically, the dynamic control algorithm of this invention is a core software logic program running within the central control unit. It achieves closed-loop intelligent control from environmental perception to precise execution. This algorithm periodically collects environmental parameters such as seawater temperature, salinity, and turbidity, and preprocesses them to eliminate noise interference. Subsequently, a fusion calculation model integrates these parameters into a quantitative bioattachment risk assessment value. This model can be expressed in a linear weighted form as follows: ,in , , These are the normalized values ​​for temperature, salinity, and turbidity, respectively. , , The corresponding weighting coefficients are initially set based on historical data of the target sea area; for example, a temperature coefficient can be assigned to a temperate sea area. Higher weight.

[0046] Risk assessment value obtained based on real-time calculation The algorithm dynamically determines two key operating parameters of the electrolytic antifouling unit. The output current density (I) is calculated using the formula... Confirmed, among which and The preset minimum and maximum safe current densities, This is the upper limit for risk assessment. The operating duty cycle (D) is determined using the formula... Confirmed, among which and These are the preset minimum and maximum duty cycles; these two formulas allow the antifouling strength of the electrolysis unit to be smoothly adjusted proportionally to the current environmental risk level. For example, under high temperature and high turbidity conditions in summer, the system will automatically increase the current density and operating frequency to enhance the antifouling effect.

[0047] To improve the system's long-term adaptability, the central control unit also runs a self-learning optimization algorithm; this algorithm uses actual fouling data (such as electrochemical impedance growth rate) fed back by the biofilm monitoring module. Based on this, it is compared with the model's predicted value ( The algorithm compares the prediction errors; based on the direction and magnitude of the prediction errors, it uses the gradient descent principle to adjust the weight coefficients. , , Dynamic fine-tuning can be performed, and its update logic can be expressed as follows: ,in For learning rate, This represents the weight coefficients to be optimized; through continuous learning, the system can gradually adapt to the unique environmental and biological community characteristics of a specific sea area, achieving predictive pollution prevention.

[0048] The biomimetic microstructure antifouling layer in the system constitutes the first physical barrier. Its microstructure is a rib-like arrangement that mimics the characteristics of shark skin. The key dimensions are rib width of 10-200 micrometers, height of 50-500 micrometers, and spacing of 50-300 micrometers. This size range has been optimized through biomimicry to effectively interfere with the water flow boundary layer and increase the difficulty of larval attachment. This structure can be prepared on the surface of the device substrate through processes such as laser surface texturing, mold imprinting, or 3D printing.

[0049] As an active chemical barrier, the electrolytic antifouling unit employs an optimized combination of a titanium anode with a mixed metal oxide coating and a titanium or stainless steel cathode. This configuration ensures high catalytic activity and long-term stability during seawater electrolysis. The electrode arrangement is designed with strict electromagnetic compatibility to ensure that it does not interfere with the energy transmission electromagnetic field of the core of the wireless power supply equipment during operation. The concentration of hypochlorite ions generated during electrolysis is maintained within an environmentally friendly range of 0.1-0.5 mg / L through intelligent control.

[0050] The biofilm monitoring module, based on electrochemical impedance spectroscopy, assesses surface fouling status in situ by periodically measuring impedance changes (Z) at the integrated sensor interface. Mechanical cleaning is triggered using a dynamic threshold strategy. Dynamically adjusted according to the cumulative operating time t of the equipment: ,in As the initial threshold, The time factor is used; this design allows the system to tolerate a slightly thicker biofilm after long-term operation before triggering cleaning, optimizing maintenance frequency and cost.

[0051] The following case study illustrates the complete implementation of this system using a specific application of a wireless charging docking station for offshore AUVs. The charging docking station is a cylindrical titanium alloy structure, with its outer shell (except for the top charging window) laser-machined into a biomimetic rib array measuring 80 micrometers wide, 180 micrometers high, and 130 micrometers apart. Four sets of mesh electrolytic electrodes are symmetrically arranged on the side walls, and electromagnetic simulation has verified that they do not interfere with the wireless charging magnetic field. The initialization parameters of the central control unit are set as follows: =0.6, =0.3, =0.1; I_min=15mA / m², =120mA / m 2 ; =10%, =40%; Initial threshold for biomembrane impedance = The time coefficient k = 0.0002 / day.

[0052] After system deployment, it operates in low-power mode (I≈20mA / m², D≈12%) when the water temperature is 12℃ in spring; it automatically switches to enhanced mode (I≈85mA / m²) when the water temperature rises to 25℃ in summer. 2 (D≈32%); After running for three months, the self-learning algorithm fine-tuned the temperature weight α from 0.60 to 0.61 based on actual monitoring data; When running for 380 days, the dynamic threshold... Rise to approximately 1291 At this time, the monitoring impedance remained stable at 1320. The system automatically summons a remotely operated vehicle (ROV) for precise cleaning via underwater acoustic communication. Throughout the two-year service period, the core functional areas of the charging dock remain highly clean, wireless charging efficiency decays by less than 2%, and the average annual comprehensive energy consumption is reduced by more than 70% compared to traditional solutions. Only one external maintenance is required, fully verifying the high efficiency, intelligence, and engineering practicality of the system of this invention.

[0053] In one specific embodiment, a biofilm monitoring module is also included, which detects the biofilm adhesion status on the surface of the biomimetic microstructure antifouling layer based on electrochemical impedance spectroscopy.

[0054] In this embodiment, a higher level of intelligent self-learning capability is introduced. The "self-learning optimization algorithm" refers to the system's ability to automatically adjust the parameter weights in the fusion calculation model based on long-term historical data (such as environmental parameter time series and electrolysis operation records) and antifouling effect feedback (the most direct data from the biofilm monitoring module). , , The purpose is to make the system's risk assessment model continuously approximate and adapt to the actual marine environment in which it operates. For example, in a specific sea area, if the system finds that the actual fouling rate is always higher than the model's predicted value when salinity fluctuates within a certain range, then the self-learning algorithm will gradually increase the weighting coefficient of salinity. This will cause the system to calculate a higher risk value under similar salinity conditions in the future. This triggers stronger anti-fouling measures. This process gives the system the potential for predictive maintenance.

[0055] In one specific embodiment, a mechanical cleaning module is also included; the central control unit is configured to activate the mechanical cleaning module when the impedance value detected by the biofilm monitoring module exceeds a set threshold.

[0056] In this embodiment, a system status monitoring and backup cleaning mechanism is jointly constructed. The "biofilm monitoring module based on electrochemical impedance spectroscopy" is an advanced in-situ, non-destructive monitoring method. Its principle is as follows: a micro-electrode sensor is integrated or deployed on the device surface, and a small alternating current signal is applied periodically to measure its impedance. When a microbial film begins to form and grow on the surface, the electrochemical properties of the electrode / solution interface change, leading to an increase in the measured impedance value (Z). Therefore, the growth trend and value of impedance Z can quantitatively reflect the biofilm's attachment status. When the monitored impedance value "exceeds a set threshold," it indicates that the first two barriers (biomimetic physics and intelligent electrolysis) may have partially failed, forming a biofilm layer that needs to be cleaned. At this time, the central control unit "activates the mechanical cleaning module." This module can be an automatic scraper integrated into the device or a remotely summoned underwater robot (ROV) to precisely clean a specific area, thereby restoring surface cleanliness.

[0057] In one specific implementation, the set threshold is dynamically adjusted based on the cumulative running time of the system.

[0058] In this embodiment, the trigger threshold for mechanical cleaning has been optimized to make it more adaptable. The phrase "setting the threshold dynamically adjusts according to the system's cumulative running time" means that the conditions for triggering cleaning are not static. This logic can be expressed by the formula: .in, It is the dynamic threshold when the running time is t. It is the initial threshold (set based on the baseline impedance of the clean surface). It is a small positive coefficient. This means that as the equipment remains in service on the seabed for longer ( With the increase of ), the system allows for a slightly thicker biofilm on the surface (i.e., higher impedance). Cleaning is only triggered when the fouling is minimal. This is because after long-term operation, occasional light fouling may have limited impact on equipment performance, while excessively frequent cleaning will increase maintenance costs; this dynamic adjustment strategy achieves a dynamic balance between anti-fouling effectiveness and maintenance economy.

[0059] In one specific embodiment, the underwater wireless power supply device is the transmitter or receiver of an underwater wireless energy transmission device, and the arrangement of the biomimetic microstructure antifouling layer and the electrolytic antifouling unit avoids the electromagnetic induction core area of ​​the device.

[0060] This embodiment emphasizes the engineering adaptability of the invention in the specific scenario of "undersea wireless power supply equipment". Wireless power transmission, especially based on electromagnetic induction, is highly dependent on the coupling of electromagnetic fields between the transmitter and receiver. Therefore, the deployment of the anti-fouling system must be designed for electromagnetic compatibility. The arrangement of the biomimetic microstructure anti-fouling layer and the electrolytic anti-fouling unit avoids the core electromagnetic induction area of ​​the device. This means that during the device design phase, it is necessary to identify the core area crucial to energy transmission (usually the plane where the coil is located and the near-field space) through electromagnetic field simulation or experiments, and ensure that the biomimetic coating and electrolytic electrodes (especially metal electrodes and the induced magnetic field generated by their operating current) do not cover or intrude into this area, or to use non-metallic, low-permeability special materials and designs to fundamentally prevent the anti-fouling system from interfering with the core power supply function.

[0061] Secondly, see Figure 2 This application provides a method for preventing the growth of marine organisms using the system described above, comprising the following steps:

[0062] S110. Prepare the biomimetic microstructure antifouling layer on the outer surface of the underwater wireless power supply device;

[0063] S120. Install the electrode pair of the electrolytic antifouling unit on the surface area of ​​the underwater wireless power supply device;

[0064] S130. The central control unit runs the dynamic control algorithm to control the operating parameters of the electrolytic antifouling unit based on the real-time collected seawater environmental parameters.

[0065] In one specific implementation, the following steps are also included:

[0066] S140. Monitor the surface condition of the biomimetic microstructure antifouling layer using the biofilm monitoring module;

[0067] S150. When monitoring data indicates the presence of biofilm, the mechanical cleaning module is triggered by the central control unit to perform cleaning.

[0068] Example 2

[0069] This embodiment provides a specific implementation plan for an "AUV autonomous wireless charging station" applied in a seabed observation network, aiming to demonstrate in detail how to concretize and engineer the system of the present invention so that those skilled in the art can understand and implement it.

[0070] Assuming the charging station is deployed on a near-shore continental shelf at a water depth of approximately 50 meters, it provides wireless charging services for autonomous underwater vehicles (AUVs) that periodically conduct hydrological surveys. The charging station itself is a cylindrical titanium alloy structure, with an electromagnetic induction wireless charging transmitting coil array embedded in the top platform, which is its core functional area.

[0071] First, the first-level physical barrier is constructed: a biomimetic microstructure anti-fouling layer. During the factory manufacturing stage, the entire titanium alloy shell of the charging pile (except for necessary areas such as the top coil window, optical communication window, and electrical interface) undergoes surface texturing using an ultrashort pulse laser. The processing parameters are optimized to form a regularly arranged micron-level rib structure on the surface, with specific dimensions controlled as follows: rib width (W) 80±10 microns, height (H) 180±20 microns, and the spacing (D) of the grooves between adjacent ribs 130±15 microns. After processing, the surface is micro-polished to remove slag and burrs generated by laser processing, followed by anodizing to generate a robust titanium oxide ceramic layer. This layer itself has excellent corrosion resistance and solidifies and protects the microstructure. This process makes the charging pile shell itself a large-scale sharkskin-like anti-fouling surface.

[0072] Secondly, a second-level chemical barrier is deployed: an intelligent electrolytic anti-fouling unit; four sets of electrolytic electrodes are symmetrically installed on the side wall of the charging pile, approximately 30 cm below the top coil array. Each set of electrodes contains a [specification missing]. The device consists of a mesh DSA anode (titanium-based, IrO2-Ta2O5 coated) and a titanium mesh cathode of the same size, which are fixed parallel to each other on an insulated composite material support. The electrode plane is approximately 5 cm from the surface of the charging pile. This location has been verified by electromagnetic simulation, and the extremely low-frequency stray magnetic field generated during operation has negligible interference with the main charging magnetic field at the top operating frequency of 100 kHz. The electrodes are connected to a dedicated power module sealed inside the pressure chamber of the charging pile via seawater-resistant cables. This power module can be programmed by a central controller to output specific DC pulse currents.

[0073] The system's "nerve center" is the central control unit, whose hardware is an industrial-grade embedded computer. We configured its initial algorithm parameters as follows: For this sea area, temperature is the dominant factor; the initial weights for environmental parameters are set as α=0.6 (temperature), β=0.3 (salinity), and γ=0.1 (turbidity); electrolysis parameters are set as minimum current density I_min=15mA / m², maximum current density I_max=120mA / m², and the risk assessment upper limit R_max corresponds to the highest temperature and high turbidity conditions in summer; duty cycle range D_min=10%, D_max=40%, and pulse period is 10 minutes. Biofilm monitoring uses a small three-electrode EIS sensor integrated into the center of the pile bottom, with its initial threshold Z_0 set to 1200 ohms (based on factory cleaning tests), and the time coefficient k set to 0.0002 / day. The self-learning algorithm runs once every four weeks, with a learning rate η=0.03.

[0074] The system is now simulated for a full year. In spring (water temperature 12°C), the system calculates a low R value, and the electrolysis unit operates intermittently in a low-power mode of approximately I=25mA / m² and D=15%. Entering summer (water temperature rises to 25°C, turbidity increases), the R value rises significantly, and the control system automatically upgrades the electrolysis mode to a higher intensity mode of I=85mA / m² and D=32%. Throughout summer and autumn, the surface impedance monitored by the EIS sensor rises slowly. The self-learning algorithm is first triggered in autumn. It compares the measured impedance growth rate in summer with the model prediction and finds that the actual growth is slightly faster. Therefore, it automatically fine-tunes the temperature weight α from 0.60 to 0.61, making the system more "sensitive" to high temperatures.

[0075] When the charging station has been in operation for 380 days, the cumulative operating time is t=380; at this time, the dynamic threshold Z_th=1200. (1+0.0002 (380)≈1291 ohms. The EIS sensor measured an impedance of approximately 1320 ohms for a week, exceeding the dynamic threshold. The central control unit then sent a maintenance request to the shore-based control center via an underwater acoustic communication link, including the equipment ID, fault type (excessive biofilm adhesion), and location information. The control center dispatched a regularly inspected ROV to the charging station. Upon arrival, the ROV used machine vision to identify the contaminated areas on the bottom of the charging station and operated a robotic arm to carefully clean them with a soft rotating brush. After cleaning, the ROV's miniature camera confirmed that the surface was clean and sent a "cleaning complete" signal to the charging station via a short-range underwater acoustic link. Upon receiving the signal, the charging station control system reset the EIS monitoring reference baseline, and the system re-entered intelligent monitoring operation.

[0076] Through the implementation of this embodiment, the top charging area of ​​the AUV wireless charging pile maintained an extremely high level of cleanliness throughout its two-year service period, with wireless charging efficiency degradation controlled to within 2%; the annual energy consumption of the electrolytic anti-fouling unit was less than 6 Wh / day. The entire system only required external robot maintenance once, reducing maintenance costs by more than 60% compared to traditional solutions (which may require manual or robotic cleaning every six months). This fully demonstrates the feasibility and significant advantages of the system of this invention in achieving efficient, long-lasting, intelligent, and low-maintenance anti-fouling on underwater wireless power supply equipment.

[0077] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
