[0001] The present invention relates to the field of intelligent propulsion for a ship's main propulsion manipulator, and in particular to an intelligent propulsion system for a ship's main propulsion manipulator. Background Art

[0002] With the continuous growth of global trade and the continuous advancement of marine resource development, the shipping industry plays a vital role in the world economy. Traditional ship propulsion systems gradually reveal some limitations in the face of increasingly complex shipping needs. In order to improve competitiveness, shipping companies are in urgent need of improving the operating efficiency of ships, including increasing navigation speed and reducing navigation time. Traditional propulsion systems are often difficult to achieve precise control of output power, resulting in energy waste and inefficiency. Ships face various risks and challenges when sailing at sea. Traditional propulsion systems may not respond quickly and accurately when dealing with emergencies and failures, affecting the safety performance of ships. High-precision sensors can monitor various operating parameters and surrounding environmental information of ships in real time, such as speed, heading, wind speed and obstacles. These sensors provide a rich source of data for intelligent control modules, making it possible to accurately adjust the output power of propellers. The technical background of the present invention is the demand for the development of the shipping industry, the promotion of technological progress and the influence of the trend of intelligence. Under such a background, it is of great practical significance and application value to develop a system that can intelligently adjust and control the output power of ship propellers according to the received signals. Summary of the invention

[0003] In order to solve the technical problems raised by the above background technology, the present invention provides an intelligent propulsion system for a main propulsion manipulator of a ship.

[0004] The purpose of the present invention can be achieved through the following technical solutions: The present invention is an intelligent propulsion system for a ship's main propulsion manipulator, comprising a security login module, a power supply module, a data acquisition module, an intelligent propulsion analysis module, an intelligent control module, a remote monitoring module and a data center.

[0005] The security login module pairs the set personnel biometric information with the intelligent propulsion system and unlocks the ship's intelligent propulsion system. The specific acquisition process is as follows: The output end of the security login module is connected to the input end of the data center. Each person sends personal information to the data center through the security login module. The personal information includes name, ID number and fingerprint image. The data center receives the personal information, divides the personal information into a personal information set, and marks the person corresponding to the personal information set as an authorized person. Each authorized person captures the fingerprint screenshot information of the current authorized person through the ship control display screen, extracts the fingerprint image corresponding to the data center, and matches the fingerprint screenshot information of the current authorized person with the fingerprint image. If the match is successful, the control interface of the authorized person is entered. If the match fails, the information interface is exited. The security login module determines that the current person is not an authorized person and generates an abnormal signal and sends it to the sound and light alarm device. The sound and light alarm device receives the abnormal signal and sends a reminder alarm.

[0006] The power supply module dynamically adjusts power distribution according to the load changes and propulsion requirements of each connected ship. The specific acquisition process is as follows: The input end of the power supply module is connected to the output end of the ship's main power grid. A load sensor is installed on the ship's main power grid to monitor the power demand of various devices on the ship in real time. The devices include intelligent propulsion systems, lighting, communication and navigation equipment, etc. When the load sensor obtains the current startup status of the device and consumes current, the device is marked as a load device, and the running number of each load device is collected in real time, marked as GF, and the running number of each load device is divided into multiple load device number intervals. The current parameter values ​​corresponding to the multiple load device number intervals are collected in real time. Each load device number interval corresponds to a current parameter value, and the current parameter values ​​of each load device number interval are obtained. The average value of each current parameter value obtained is calculated to obtain the current average value of each load device, marked as , arrange the obtained current parameter values ​​from large to small, obtain the maximum current value and the minimum current value, subtract the minimum current value from the maximum current value to obtain the current difference value, marked as , obtain the current monitoring time point corresponding to the maximum current value, marked as the maximum monitoring time point, obtain the current monitoring time point corresponding to the minimum current value, marked as the minimum monitoring time point, connect the maximum monitoring time point and the minimum monitoring time point to obtain the current difference monitoring period, marked as GS, calculate by obtaining the number of load devices running, current average value, current difference value and current difference monitoring period, and use the formula The total operating energy value GFD of each load device is obtained, wherein B1, B2, B3 and B4 are preset proportional coefficients, j represents the serial number of each load device, and n represents the total number of load devices. The preset total operating energy threshold of the data center is extracted, and the total operating energy value is compared with the preset total operating energy threshold. If the total operating energy value is greater than the preset total operating energy threshold, an over-energy signal is generated and sent to the ship's main power grid. The ship's main power grid receives the over-energy signal and generates an auxiliary instruction and sends it to the power storage device. The power storage device includes an auxiliary motor and a storage battery pack. The power storage device receives the auxiliary instruction and starts the operating state, and sends the generated electricity to the ship's main power grid for distribution.

[0007] The data acquisition module collects data information in real time according to each sensor and sends the data information to the intelligent propulsion analysis module. The specific acquisition process is as follows: The output end of the data acquisition module is connected to the input end of the intelligent propulsion analysis module. The ship load sensor is installed at the bottom of the cargo hold and the deck of the ship. The weight information of the current cargo is collected in real time through the ship load sensor to obtain the cargo weight parameters of the current ship. Install a wind speed sensor on the hull to collect wind speed information outside the hull in real time and obtain current wind speed parameter information; The acquired ship cargo weight parameter and wind speed parameter information are sent to the intelligent propulsion analysis module.

[0008] The intelligent propulsion analysis module performs analysis based on the parameter information sent by the receiving data acquisition module. The specific acquisition process is as follows: The output end of the intelligent propulsion analysis module is connected to the input end of the intelligent control module. The intelligent propulsion analysis module analyzes the received ship cargo weight parameter and wind speed parameter information, collects images of the ship cargo in various directions through a high-definition camera, and obtains images of the ship cargo in various directions, thereby constructing a three-dimensional image corresponding to the ship cargo, and then obtains the total cargo volume corresponding to the ship cargo through analysis. The cargo weight and total cargo volume corresponding to the ship cargo constitute the ship immersion depth corresponding to the current ship cargo, which is marked as , monitor the current ship wind speed parameter information, obtain the wind speed intensity value and the wind vector direction, each wind vector direction includes forward wind, side wind and reverse wind, match each wind speed intensity value with each wind vector direction, obtain each wind speed intensity value corresponding to each wind vector direction, calculate the average wind speed intensity value corresponding to each wind vector direction, and mark it as , It is represented by each wind direction, and the duration of each wind direction is monitored. The time point when the ship starts running is marked as the start time point, and the time point when the ship receives the change of the wind direction is marked as the end time point. The start time point and the end time point are connected to obtain the operation time period of the current wind direction. The operation time period of each wind direction is obtained by statistics and marked as Similarly, the running distances of each wind vector direction are obtained and marked as , calculate the operating time periods, operating distances, average wind speed intensity values ​​and ship immersion depth corresponding to the wind direction, and use the formula The propulsion compensation value BK of each wind vector direction is obtained, where C1, C2, C3 and C4 are preset proportional coefficients. If the propulsion compensation value obtained is side wind and head wind, a reverse signal is generated and sent to the intelligent control module. Otherwise, a forward signal is generated and sent to the intelligent control module.

[0009] The intelligent control module adjusts and controls the ship's engine output power according to the received signal. The specific acquisition process is as follows: The intelligent control module receives the reverse signal, generates an enhanced compensation instruction according to the propulsion compensation value, and sends it to the engine processing terminal. The engine processing terminal receives the enhanced compensation instruction, increases the current engine output power to adjust the ship's speed; the intelligent control module receives the forward signal, generates a reduced compensation instruction according to the propulsion compensation value, and sends it to the engine processing terminal. The engine processing terminal receives the reduced compensation instruction, reduces the current engine output power to adjust the ship's speed.

[0010] The remote safety monitoring module monitors surrounding obstacles in real time based on radar sensors and automatically adjusts the propulsion strategy. The specific acquisition process is as follows: Radar sensors are installed around the ship, with the ship as the center point and the radar sensor sensing as the radius to form a circular sensing range, and information data of obstacles within the circular sensing range is obtained in real time. The obstacles include reefs, shipwrecks and marine life. The obstacle data information is obtained, the obstacle data information is integrated, noise and interference are removed, and processed obstacle information is obtained. The position and size of the obstacle in the processed obstacle information are extracted, the current ship position and the obstacle position are connected to obtain the distance value between the ship and the obstacle, the current ship speed is obtained, and the remaining collision time is calculated according to the ship speed and the distance value. The preset collision time range of the data center is extracted, and the remaining collision time is compared with the preset collision time range. If the remaining collision time is greater than the preset collision time range, a mitigation signal is generated and sent to the intelligent propulsion system. The intelligent propulsion system receives the mitigation signal and slowly reduces the current driving speed and changes the driving direction. If the remaining collision time is less than the preset collision time range, an emergency signal is generated and sent to the intelligent propulsion system. The intelligent propulsion system receives the emergency signal, stops the current engine operation state and urgently changes the driving direction.

[0011] Compared with the prior art, the beneficial effect of the present invention is that the intelligent control module can adjust the propeller output power in real time and accurately according to various signals. This enables the ship to operate with the most optimized power under different navigation conditions, avoids the situation of excess or insufficient power, improves the energy utilization efficiency, and thus improves the overall operation efficiency of the ship, and can quickly respond to changes in the surrounding environment, wind speed and obstacles, etc. When encountering adverse environmental factors, the power can be adjusted in time to ensure the stable navigation of the ship, reduce the speed fluctuation and energy consumption increase caused by environmental changes, and enable the ship to maintain a high operating efficiency in various complex environments. The remote monitoring module dynamically monitors the operating status of the ship. Once an abnormal situation is found, the propeller power can be quickly adjusted, and corresponding safety measures can be taken to reduce the risk of accidents. Accurate power adjustment can significantly reduce the energy consumption of the ship, adjust the propeller power according to actual needs, and avoid energy waste. As time goes by, the system will become more and more adapted to different navigation conditions and mission requirements, providing continuous optimization and improvement for ship operations.
