[0054] In order to make the objects, technical solutions and advantages of the application clearer, the technical solutions in the application will be described clearly and completely below with reference to the drawings in the application. Obviously, the described embodiments are some embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative effort belong to the protection scope of the application.

[0055] In marine engineering and navigation, ballast water systems are critical to ensure the stability and safety of ships. Traditional ship ballast water management systems mainly rely on independently operated ballast water pumps, with each ballast water tank's water volume adjustment being handled by the corresponding water pump. Although this design is structurally simple, it has several shortcomings in practical application. First, cross-compartment water volume adjustment is difficult. Traditional ship ballast water systems lack an effective linkage mechanism between ballast water tanks. The water volume adjustment of each ballast water tank is handled by an independent water pump, which cannot achieve cross-compartment water volume transfer. This structure limits the overall balance of the ship when the water volume of a certain compartment needs to be adjusted, as it cannot be balanced by adjusting the water volume of other compartments. Second, the control system response is lagging. Traditional ballast water regulation systems often use manual or preset program control methods, which cannot meet the real-time changes in navigation requirements. Especially in harsh sea conditions or sudden changes in ship load, the system's adjustment often lags behind the actual needs, which can easily lead to unstable conditions such as ship pitch and roll, and even cause safety accidents. In addition, energy consumption and maintenance costs are high. Traditional ballast water systems usually have low operating efficiency, especially when the ballast water volume needs to be adjusted frequently, resulting in significant energy consumption. Moreover, due to the complex structure of the system, each water pump and pipe operates independently, making maintenance work tedious and costly. Long-term operation requires frequent maintenance and performance degradation, increasing the operating cost of the ship. Finally, the system has poor redundancy. Since the water pumps and pipes of the traditional ballast water system operate independently, there is no effective redundancy design. Once a ballast water pump or pipe fails, the water volume adjustment of the corresponding tank will be affected, seriously affecting the stability of the entire ship. This design flaw makes the traditional system unable to provide sufficient emergency response capability in the face of equipment failure or unexpected situations.

[0056] In recent years, with the development of ship automation control technology, ballast water management systems have gradually introduced automated control methods such as fuzzy control, neural network control, etc. However, these technologies still have many limitations in practical application. For example, fuzzy control systems perform well in handling nonlinear and complex dynamic environments, but their computational complexity is high, and they lack real-time performance, making it difficult to respond quickly in complex marine environments. Similarly, neural network control methods have self-learning capabilities, but their training process is complex and relies on a large amount of historical data, making them not flexible enough for plug-and-play applications.

[0057] To solve the problems in the prior art, the present invention proposes a dynamic adjustment method for ship ballast water to achieve intelligent adjustment of ship ballast water. The following describes the dynamic adjustment method for ship ballast water, as shown in Figure 1 including but not limited to the following steps:

[0058] Step 110, obtaining water level data set, attitude data set and water pressure data set through sensors arranged at preset positions of the ship, the water level data set including water level data at each preset position, the attitude data set including attitude data at each preset position, and the water pressure data set including water pressure data at each preset position.

[0059] In this step, various types of data related to the state of the ship are obtained through sensors arranged at preset positions of the ship, including water level data set, attitude data set and water pressure data set. The specific implementation is as follows:

[0060] The water level sensors are installed in each ballast tank to monitor the water level changes of each tank in real time, forming a water level data set. This data set contains water level data at each preset position (such as front tank, middle tank and rear tank) for subsequent analysis.

[0061] The attitude sensors are arranged on the centerline of the ship to monitor the trim angle and the roll angle of the ship, obtaining an attitude data set. This data set includes attitude data at each preset position, ensuring a comprehensive reflection of the inclination state of the ship.

[0062] The water pressure sensors are arranged in the pipeline network to monitor the water pressure flowing through the pipeline, forming a water pressure data set. This data set includes water pressure data at each connected pipeline position, providing an important basis for the water flow state.

[0063] All sensors transmit data to the central control system of the ship through wired or wireless means for real-time processing and analysis.

[0064] Step 120, determining whether the ship is in a balanced state according to the water level data set and the attitude data set, and when the ship is in an unbalanced state, determining a water quantity adjustment scheme through a ballast water allocation optimization model.

[0065] In step 120, whether the ship is in a balanced state is determined according to the water level data set and the attitude data set obtained in step 110. The specific implementation is as follows:

[0066] The water level data set is used to calculate the center of gravity coordinates of the ship in combination with the position coordinates of each ballast tank 、 、 . Then, the trim angle and the roll angle of the ship are calculated according to the center of gravity coordinates. If the center of gravity coordinates are within the preset range and the inclination angles are within the designed safety range, it is determined that the ship is in a balanced state; if not, it is determined that the ship is in an unbalanced state and needs to be adjusted by ballast water.

[0067] When the ship is in a non-equilibrium state, a water quantity adjustment scheme is determined by a ballast water distribution optimization model, and the aforementioned data is used to generate a water quantity adjustment scheme by the ballast water distribution optimization model. The scheme includes a specific amount of water transferred from one or more ballast water tanks to achieve equilibrium.

[0068] In step 130, water pump operation instructions and valve opening and closing instructions are generated according to the water quantity adjustment scheme to restore the ship to an equilibrium state.

[0069] The water pump operation instructions are used to control the water pump to control the water level of the ballast water tank, and the valve opening and closing instructions are used to control the valve of the pipeline network to control the water level of the ballast water tank, and each ballast water tank is connected through the pipeline network.

[0070] In step 130, water pump operation instructions are generated according to the water quantity adjustment scheme to control the start and stop of the water pump to adjust the water level of the ballast water tank. The instructions will specifically guide the operation of the water pump, such as "start water pump A and transfer water from compartment 1 to compartment 2". Valve opening and closing instructions are generated to control the valves in the pipeline network to adjust the water level of the ballast water tank. These instructions will specifically indicate the state of the valve, such as "open valve 1 and close valve 2". The above instructions are executed by the control system to adjust the water level of each ballast water tank and ultimately restore the ship to an equilibrium state.

[0071] The present application uses sensors to obtain data, accurately determines the equilibrium state of the ship, and generates corresponding adjustment instructions according to the optimization model to ensure the stability and safety of the ship under various navigation conditions.

[0072] As a further optional embodiment, the step of obtaining water level data set, attitude data set and water pressure data set by sensors specifically includes:

[0073] The water level data of the ballast water tank is obtained by the water level sensor arranged in the ballast water tank.

[0074] The attitude data of the ship is obtained by the attitude sensor arranged in the center axis of the ship.

[0075] The water pressure data of the pipeline is obtained by the pressure sensor arranged in the pipeline network.

[0076] In this embodiment, a water level sensor is arranged in each ballast water tank to monitor and collect real-time water level data of each ballast water tank. The water level change of each ballast water tank is a key monitoring parameter in the ballast water distribution process.

[0077] The water level data set is formed by the water level sensor, which includes the water level information of each water tank in the ballast water tank at different time points. This information is directly used for calculation of the center of gravity of the ship and subsequent water quantity adjustment scheme.

[0078] The attitude sensor is installed at the center axis of the ship to collect the pitch angle and roll angle of the ship. Since the center axis position can accurately reflect the overall attitude of the ship, the attitude sensor installed at this position can obtain more accurate data.

[0079] The attitude sensor monitors the attitude change of the ship in real time to form an attitude data set. This data set can be used to determine the inclination state of the ship to determine whether the ship is in a balanced state.

[0080] A pressure sensor is arranged in the pipeline network connected to the ballast water tank to monitor the pressure change of the water flow in real time. The pressure sensor can capture the flow state of the ballast water in each pipeline, especially during the water quantity adjustment process, and the pressure change is an important monitoring index.

[0081] The water pressure data in the pipeline is obtained by the pressure sensor to form a water pressure data set. This data set is used to optimize the distribution of water flow to ensure effective allocation of water flow between each ballast water tank.

[0082] As a further optional embodiment, the step of determining whether the ship is in a balanced state according to the water level data set and the attitude data set specifically includes:

[0083] According to the water level data set and the position coordinates of the ballast water tank, the center of gravity coordinates of the ship are determined.

[0084] When the center of gravity coordinates are within a preset center of gravity range and the attitude data of the ship are within a preset inclination angle range, the ship is in a balanced state; otherwise, the ship is in an unbalanced state.

[0085] In this embodiment, first, the water quantity in each ballast water tank is determined according to the water level data set. Combined with the specific position coordinates of each ballast water tank, including its transverse (X-axis), longitudinal (Y-axis) and vertical (Z-axis) coordinates relative to the centerline of the ship body, the center of gravity position of the entire ship is calculated.

[0086] A reasonable center of gravity range is set in advance according to the ship design and navigation requirements. The center of gravity range is the center of gravity coordinate interval of the ship in the normal balanced state, which is used to ensure the stability of the ship in the balanced state.

[0087] The current calculated center of gravity coordinates , , are compared with the preset range. If the center of gravity exceeds the range, the distribution of the ballast water of the ship is unbalanced, which may cause the ship to tilt or be unstable.

[0088] The pitch angle and roll angle provided by the attitude sensor Used to assess the ship's attitude. The degree of tilt of the ship is determined in real time using an attitude dataset.

[0089] The calculated tilt angle is compared with the preset safe tilt angle range. If the ship's heel angle... and tilt angle If all angles are within the preset tilt angle range and the ship's center of gravity coordinates are also within the preset center of gravity range, then the ship is in a balanced state.

[0090] If the center of gravity coordinates or tilt angle do not meet the above conditions, the ship is in an unbalanced state and ballast water needs to be adjusted to restore balance.

[0091] As a further optional embodiment, the step of determining the ship's center of gravity coordinates based on the water level dataset and the position coordinates of the ballast tanks specifically includes:

[0092]

[0093] in, , , Let be the coordinates of the ship's center of gravity in the X, Y, and Z directions at time t. , and It is the first The lateral and longitudinal coordinates of each ballast tank relative to the ship's centerline.

[0094] In this embodiment, firstly, water level data for each ballast water tank is acquired in real time using water level sensors installed in each ballast water tank. Based on the geometric dimensions and water level of each ballast water tank, the current water volume of each ballast water tank is calculated. ,in i This represents the i-th ballast water tank. t Indicates the current time.

[0095] Water volume data from ballast tanks and the position coordinates of each ballast water tank , and Calculate the coordinates of the ship's center of gravity in the X, Y, and Z directions. The specific calculation formula is as follows:

[0096]

[0097] in, For time Water volume, , , Let be the coordinates of the ship's center of gravity in the X, Y, and Z directions at time t. 、 and is the first transverse and longitudinal coordinates of the ballast water tank relative to the ship centerline, n represents the total number of ballast water tanks.

[0098] As the ballast water is deployed and the ship attitude changes, the center of gravity coordinates 、 、 will dynamically change over time t . Real-time calculation of the center of gravity can help determine the stability of the ship and trigger water adjustment in time to restore the balance of the ship.

[0099] Through the above steps, the change of the center of gravity of the ship during navigation can be accurately calculated, which helps to maintain the balance of the ship by adjusting the distribution of ballast water in real time, and ensures the safety and stability of the ship in complex navigation environment.

[0100] As a further optional embodiment, the ballast water deployment optimization model is constructed by the following steps:

[0101] Define the decision variables and state variables of the ballast water deployment optimization model;

[0102] Determine the objective function of the ballast water deployment optimization model;

[0103] Determine the constraint conditions of the ballast water deployment optimization model.

[0104] As a further optional embodiment, the objective function is as follows:

[0105]

[0106] wherein, is the water volume at time , represents the change in water volume from time to time , is the total length of time, is the total number of ballast water tanks.

[0107] As a further optional embodiment, the constraint conditions include center of gravity balance constraint, ship attitude stability constraint, water conservation constraint and ballast water tank capacity constraint;

[0108] The center of gravity balance constraint is as follows:

[0109]

[0110] wherein, , , Let be the coordinates of the ship's center of gravity in the X, Y, and Z directions at time t. and It is the first The transverse and longitudinal coordinates of each ballast tank relative to the ship's centerline;

[0111] The ship's attitude stability constraints are as follows:

[0112]

[0113] in, and Indicates the time of the ship The pitch and roll angles at any given moment;

[0114] The water conservation constraint is as follows:

[0115]

[0116] in, For time Water volume, Indicates water from the cabin Flow to the cabin Water flow rate Indicates water from the cabin Flow to the cabin Water flow rate;

[0117] The ballast water tank capacity constraints are as follows:

[0118]

[0119] in, Indicates the first Minimum capacity of each ballast tank, Indicates the first The maximum capacity of each ballast water tank.

[0120] In this embodiment, it is first necessary to define the decision variables and state variables of the ballast water allocation optimization model: Decision variables: Definition In time t arrive t During the +1 time period, from the ballast water tank i To the ballast water tank j The amount of water transferred.

[0121] State variables: Definition In time t Time of the first i The water volume of each ballast tank; and the time of the ship's operation. t The center of gravity of a moment , , and tilt angle and tilt angle , used to describe the attitude state of a ship.

[0122] Next, the objective function of the ballast water allocation optimization model is determined: the objective function aims to minimize the adjustment amount of ballast water to reduce unnecessary water volume changes and improve the efficiency and accuracy of allocation. Its specific expression is:

[0123]

[0124] in, For time Water volume, Represented as time Time Water volume changes The total length of time. This represents the total number of ballast water tanks.

[0125] Determine the constraints for the ballast water allocation optimization model: To ensure the feasibility of the model in actual operation and the stability of the ship, the following constraints must be imposed:

[0126] The center of gravity balance constraint is as follows:

[0127]

[0128] in, , , Let be the coordinates of the ship's center of gravity in the X, Y, and Z directions at time t. and It is the first The transverse and longitudinal coordinates of each ballast tank relative to the ship's centerline;

[0129] The ship's attitude stability constraints are as follows:

[0130]

[0131] in, and Indicates the time of the ship The pitch and roll angles at any given moment;

[0132] The water conservation constraint is as follows:

[0133]

[0134] in, For time Water volume, Indicates water from the cabin Flow to the cabin Water flow rate Indicates water from the cabin Flow to the cabin Water flow rate;

[0135] The ballast water tank capacity constraints are as follows:

[0136]

[0137] in, Indicates the first Minimum capacity of each ballast tank, Indicates the first The maximum capacity of each ballast water tank.

[0138] Through the above steps, a ballast water allocation optimization model that comprehensively considers the ship's center of gravity, attitude stability, and water conservation has been established. This model can dynamically allocate ballast water to achieve the ship's balance and stability under the premise of meeting the constraints.

[0139] The following describes the dynamic adjustment device for ship ballast water provided by the present invention, such as...
