Traditional oil spill recovery methods mainly rely on mechanical recovery, spraying of oil spill dispersants and controlled combustion. However, these methods have many technical defects and limitations when facing large-scale oil spills and complex sea conditions.

[0003] In addition, there are unmanned automatic towing devices, but the traction force is insufficient: although the existing unmanned automatic towing equipment (such as the automatic navigation and automatic recovery electric oil boom and its operation method disclosed in application number CN201910740094.9) can realize unmanned operation, it still has limitations in traction force and is difficult to meet the deployment and towing requirements of heavy oil booms.

[0004] There are also the following problems:

[0005] The traction of a single unmanned device is insufficient, and multiple devices need to work together. However, the existing technology has technical difficulties in multi-device collaborative control and error correction, making it difficult to achieve efficient collaborative work.

[0066] Figure 1 It is a schematic diagram of the system framework of the present invention. DETAILED DESCRIPTION

[0067] The following combination Figure 1 The present invention is described in further detail.

[0068] The present invention discloses an intelligent underwater power oil boom traction system based on multi-source collaboration, referring to Figure 1 , including a main controller, an environmental perception unit, a navigation and positioning unit, an adaptive adjustment unit, a dynamic modeling and intelligent decision-making unit, a redundant system unit, an intelligent control unit, a power management unit and multiple underwater power devices, among which,

[0069] The underwater power unit is connected to the power management unit, including a propeller, a control module, a power module and a communication module, and each underwater power unit is equipped with a local controller with autonomous decision-making capabilities;

[0070] Specifically, the underwater power unit is fixed to the oil boom through magnetic or mechanical connection, and the controller is a high-efficiency and low-noise electric thruster; the control module is equipped with a microprocessor and sensors to obtain the status of the underwater power unit, including speed, position and temperature; the power module uses a replaceable high-energy density lithium battery, and the communication module is used to communicate with other devices inside the system and an external control center, and is responsible for sending and receiving data, including status information, control instructions, environmental data, etc. At the same time, the information transmission between underwater power units adopts an anti-interference communication protocol to ensure the communication quality in complex underwater environments.

[0071] The main controller is connected to the environmental perception unit and is responsible for overall task allocation and coordination to ensure that multiple underwater power units work in coordination according to the predetermined strategy;

[0072] Specifically, the main controller includes a collaborative control strategy module, which adopts a consistency algorithm, such as the Leader-Follower algorithm, the Flocking algorithm, etc., to realize information exchange and collaborative actions among multiple underwater power devices. Through iteration, the state of each underwater power device gradually tends to be consistent, thereby realizing coordinated and consistent task execution. The real-time data provided by the environmental perception module is used as the input of the consistency algorithm;

[0073] Its working principle is:

[0074] Information exchange: Each underwater power device exchanges status information, such as position, speed, direction, etc., with other adjacent devices through the communication module;

[0075] State update: Each underwater power device uses a consensus algorithm to update its own state based on the neighbor information received. This process is usually implemented through first-order differential equations or difference equations;

[0076] Iterative convergence: Through multiple iterations, the states of all underwater power devices gradually converge to a common value or reach a predetermined coordination state;

[0077] The environmental perception unit is connected to the adaptive adjustment unit and the navigation and positioning unit, and is integrated with sonar, camera and flow meter, combined with machine vision technology, to identify and track the oil boom;

[0078] The navigation and positioning unit includes an acoustic sensor and an optical sensor to realize multi-source acoustic and optical fusion positioning. The acoustic sensor is used for long-distance positioning, and the optical sensor is used for short-distance precise positioning.

[0079] The adaptive adjustment unit is connected with the dynamic modeling and intelligent decision-making unit, including a decision-making system based on fuzzy logic or neural network, and a data fusion system based on Kalman filtering or multi-sensor data fusion algorithm;

[0080] The decision system based on fuzzy logic maps the input value to the fuzzy set, performs fuzzy operation and reasoning, and finally obtains the output value. The steps of implementing the decision system based on fuzzy logic in the present invention are as follows:

[0081] 1. Input variables: speed, position;

[0082] 2. Membership function: defines fuzzy sets of speed and position, such as "low", "medium", and "high";

[0083] 3. Rule base: define If-Then rules, such as "if the speed is high and the position is deviated, then slow down";

[0084] 4. Reasoning and defuzzification: Perform fuzzy reasoning based on the rule base to obtain the control signal and defuzzify it into a specific value;

[0085] In the decision-making system based on neural network, the neural network simulates the working principle of biological neurons, performs complex nonlinear mapping and pattern recognition, has adaptive learning ability, and can adjust its own parameters according to input data. The steps implemented in the present invention are:

[0087] 2. Training data: collect speed, position and corresponding control signals;

[0088] 3. Training process: Use the back-propagation algorithm to adjust the network weights and biases to make the output as close to the desired control signal as possible;

[0089] 4. Application: Output corresponding control signals according to new speed and position data.

[0090] In the data fusion system based on the Kalman filter algorithm, the Kalman filter is a recursive algorithm used to estimate the state of a dynamic system. By combining the dynamic model of the system and the sensor measurement data, an optimal estimate is provided. The steps implemented in the present invention are:

[0091] 1. State prediction: predict the speed and position at the next moment based on the dynamic model of the system;

[0092] 2. Covariance prediction: predict the covariance matrix at the next moment;

[0093] 3. Measurement update: Combine sensor measurement data to update estimates of speed and position;

[0094] 4. Iteration: Repeat the above steps to continuously update the estimates of speed and position

[0095] In a data fusion system based on a multi-sensor data fusion algorithm, multi-sensor data fusion improves the perception accuracy and reliability of the system by combining data from multiple sensors. The steps implemented in the present invention are:

[0096] 1. Data preprocessing: denoising and calibrating the data from sonar, camera and current meter;

[0097] 2. Data fusion: Use Kalman filtering to fuse the data from sonar, camera and flow meter to obtain the optimal speed and position estimate;

[0098] 3. State update: Update the system’s speed and position estimates based on the fused data;

[0099] 4. Feedback adjustment: adjust the operating parameters of the sensor according to the estimated results of speed and position;

[0100] The dynamic modeling and intelligent decision-making unit is connected with the redundant system unit and the intelligent control unit, including the deep learning model and the reinforcement learning agent, and uses the system recognition model to update the model parameters in real time;

[0101] Specifically, in the dynamic modeling and intelligent decision-making unit, the deep learning model extracts high-level features from the system operation data and provides them to the reinforcement learning agent and the system identification model. The reinforcement learning agent learns the optimal strategy based on the features extracted by the deep learning model, makes real-time decisions and controls the system behavior. The system identification model builds and updates the dynamic model of the system based on the input and output data of the system and provides it to the deep learning model and the reinforcement learning agent. The adaptive adjustment unit combines deep learning, reinforcement learning and system identification technologies to adjust the working state of the system in real time and improve the flexibility and adaptability of the system, including:

[0102] 1. Deep learning model training:

[0103] Collect sensor data and control signals during system operation, design a convolutional neural network (CNN) to extract spatial features from the data, train the CNN using the collected data, adjust the network weights through the back-propagation algorithm, deploy the trained CNN into the system, and predict the system status in real time;

[0104] 2. Reinforcement Learning Agent Strategy Optimization:

[0105] Define the system's state space (such as position, speed), action space (such as acceleration, deceleration) and reward function (such as minimizing energy consumption), design a deep Q network (DQN) to learn the optimal strategy, in the simulation environment, the agent continuously adjusts the strategy through trial and error to maximize the cumulative reward, uses the gradient descent algorithm to optimize the parameters of DQN, and deploys the trained DQN strategy to the system to make real-time decisions and control system behavior;

[0106] 3. System identification model update:

[0107] Collect the input and output data of the system, select a state space model to describe the dynamic behavior of the system, use the Kalman filter algorithm to estimate the model parameters, use an independent data set to verify the model performance, and update the model parameters in real time during the operation of the system to adapt to the dynamic changes of the system;

[0108] Redundant system units, which are divided into two types: hardware redundancy and software redundancy, are used to take over functions when some devices fail. When some devices fail, the backup components take over the functions of the failed components to avoid system downtime or performance degradation, and ensure system continuity and reliability;

[0109] Specifically, two controllers are configured in the system, one as the main controller, and a backup controller is set in the redundant system unit. The backup controller and the main controller are connected through a high-speed communication link. The main controller is responsible for normal operation, and the backup controller is in standby state. The main controller and the backup controller synchronize data in real time through a high-speed communication link to ensure that the backup controller can take over at any time; a master-slave switching algorithm is set in the control system. When the main controller fails, the backup controller automatically takes over its function, detects system failures in real time through sensors and monitoring systems, and isolates failed components to prevent the spread of failures;

[0110] The system is equipped with a fault detection module to monitor the status of the main controller in real time. When a fault is detected in the main controller, it will immediately switch to the backup controller. Multiple sensors are configured at key locations to ensure that the system can still obtain accurate data even if one sensor fails. Multiple power modules are configured to ensure that the system can still supply power normally even if one power module fails. Multiple communication paths are configured to ensure that data can still be transmitted through other paths even if one path fails.

[0111] The intelligent control unit is connected to the power management unit and adopts the improved SH adaptive federated filtering method to monitor the status of each underwater power device in real time and adjust the working status according to the actual situation to achieve coordinated control and error correction of multi-source underwater power devices.

[0112] Specifically, in the intelligent control unit, the SH adaptive federated filtering method is an algorithm for multi-source data fusion and error correction, and the implementation steps are:

[0113] 1. Model the underwater multi-source integrated navigation system and obtain each navigation sensor and its error model;

[0114] 2. Based on the error model, an improved SH adaptive filtering method is proposed;

[0115] 3. In the federated filter, an improved SH adaptive filtering method is used for time update and measurement update;

[0116] 4. Through the federated filter, the data of multiple sensors are fused to obtain the optimal state estimation;

[0117] The implementation steps of the intelligent control unit are:

[0118] 1. Each underwater power device is equipped with a sensor to collect data such as position, speed, and power in real time. The sensor data is transmitted to the intelligent control unit through the communication module. The intelligent control unit monitors the status of each underwater power device in real time, analyzes the data, and identifies abnormal situations;

[0119] 2. The intelligent control unit sends control instructions to each underwater power device to adjust the operating status of the thruster. Each underwater power device adjusts its own status according to the received control instructions and feeds back the new status information to the intelligent control unit to form a closed-loop control;

[0120] The specific process is:

[0121] 1. System modeling: Model the underwater multi-source combined navigation system to obtain each navigation sensor and its error model. The error model of the position sensor can be expressed as:

[0122] x k+1 =Ax k +Bu k +w k

[0123] In the formula, x k is the state vector, u k is the control input, w k is the process noise;

[0124] 2. Error correction: Use the improved SH adaptive filtering method to correct the sensor data errors, and use Kalman filtering for state estimation and error correction:

[0125]

[0126] In the formula, k k is the Kalman gain, z k is the measurement value, H is the measurement matrix;

[0127] 3. Collaborative control: Use a consensus algorithm to achieve collaborative control of multiple underwater power devices, using the Leader-Follower algorithm:

[0128]

[0129] In the formula, u i is the control input of the ith device, N i is the neighbor set of the ith device, a ij is the adjacency matrix element;

[0130] 4. Real-time monitoring and status adjustment: The intelligent control unit monitors the status of each underwater power device in real time, analyzes data, and identifies abnormal situations. Based on the calculation results, the intelligent control unit sends control instructions to each underwater power device to adjust the operating status of the thruster. Each underwater power device adjusts its own status according to the received control instructions and feeds back the new status information to the intelligent control unit to form a closed-loop control;

[0131] The power management unit monitors the power status of each underwater power device in real time.

[0132] In a further embodiment, the system of the present invention further comprises:

[0133] A data storage module, used for storing system operation data and sensor data;

[0139] The method for using the intelligent underwater power oil boom traction system based on multi-source collaboration includes the following steps:

[0140] S1, system initialization, the main controller assigns specific tasks to each underwater power device according to the preset mission plan, including initial position, path planning and working mode;

[0141] Specifically, when the system is started, each underwater power unit establishes a connection with the main controller through the wireless communication module to ensure the stability and real-time performance of data transmission. The main controller assigns specific tasks to each power unit according to the preset task plan, including initial position, path planning and working mode. The environmental perception module is started to collect surrounding environmental data (such as water flow speed, direction, temperature, etc.) in real time, and transmit the data to the navigation and positioning unit and the adaptive adjustment unit.

[0142] S2, deployment phase: during the deployment of the oil boom, operators or automatic equipment install underwater power units on the oil boom at predetermined intervals to ensure that the power units are evenly distributed. Each power unit exchanges information with the main controller and other power units through the communication module to ensure that the status and position of each device are synchronized. The environmental perception module monitors the position and status of the oil boom in real time and provides high-precision data to support the decision-making of the navigation and positioning unit and the adaptive adjustment unit.

[0143] S3, in the towing phase, each underwater power unit adjusts the thrust and direction of the propeller according to the instructions of the main controller, and cooperates to provide sufficient traction to ensure that the oil boom operates within the predetermined area. At the same time, the navigation and positioning unit combines the data of the acoustic sensor and the optical sensor to provide high-precision positioning information to ensure the accurate deployment and towing of the oil boom. The adaptive adjustment unit dynamically adjusts the working state of each power unit according to the real-time environmental data (such as water flow speed, direction, etc.) and task requirements to ensure the flexibility and adaptability of the system. The intelligent control unit adopts the improved SH adaptive federal filtering method to perform error correction on the state of each power unit to ensure the coordination and consistency of each device;

[0144] S4, charging and battery replacement, the power management unit monitors the power status and charge state of each underwater power device in real time through voltage, current and temperature sensors. When the power is lower than the set threshold, the power management unit starts the charging process and controls the charging equipment to perform constant current charging, constant voltage charging or pulse charging to ensure that the battery is charged within a safe range. When the battery charge state is lower than the set threshold, the power management unit prompts that the battery needs to be replaced and coordinates the battery replacement process, including battery removal, installation and initialization;

[0145] S5, fault handling and redundancy management, the redundant system unit monitors the status of each underwater power device in real time, and when a device failure is detected, the redundant system is immediately activated to take over its function;

[0146] S51, the intelligent control unit analyzes the sensor data on the underwater power device, such as voltage, current, temperature, position, speed, etc., and identifies abnormal conditions, such as low voltage, high temperature, or position deviation, etc. When an abnormal condition is detected, the system issues a fault alarm and records the fault information;
