[0002] Dual-fuel bulk carriers refer to bulk carriers that can use two different types of fuels, usually ships that can use both traditional fuel and clean LNG fuel as fuel; such ships are usually equipped with dual-fuel engines and corresponding fuel storage facilities to achieve flexible fuel selection in different navigation situations to minimize emissions and improve energy efficiency; When dual-fuel bulk carriers are sailing, they are different from traditional heavy oil fuel transport ships. They are loaded with clean new energy LNG, which can reduce pollution emissions while achieving more lasting endurance support. At present, there are two modes of dual-fuel transport ships in sailing. One is the alternating and cyclic use of dual fuels, and the other is to introduce a small amount of traditional fuel mixed with LNG fuel for mixed combustion. However, although the alternating use of dual fuels can cope with more driving scenarios, it will affect the energy supply system of the hull when the fuel is switched, which poses a hidden danger in emergency scenarios. A small amount of traditional fuel mixed with LNG fuel can coordinate the use of two fuels, without the problem of switching fuels, and can cope with most driving scenarios, but the lack of dynamic and reasonable planning of the two fuels can easily cause unreasonable fuel ratios in normal scenarios, resulting in waste of resources or serious environmental pollution, and the lack of reasonable planning of fuel distribution in emergency scenarios can easily cause major hidden dangers to the safety of ship driving.

If the tracing result is There is a trend in the observed data, and The trend of observed data disappears at the interval is a relatively dynamic scene set; the remaining ship travel time intervals are relatively static scene sets; where a and b are integers; S302: In each scenario, extract the wind speed, wind direction, water flow speed and water flow direction data from the collected environmental data, and judge the angle between the wind direction, water flow direction and the ship's travel direction; if the angle between the wind direction and the ship's travel direction is , then the current wind direction is consistent with the forward direction of the hull, and the hull is not subject to wind resistance, which is propulsion; if , then the current wind direction has resistance in the direction perpendicular to the ship's travel direction, and there is propulsion in the ship's travel direction; if , then the wind resistance is the resistance in the vertical direction of the hull, and there is no propulsion force; if , then the current wind direction does not provide any propulsion force for the ship's forward movement, and there is resistance in the ship's travel direction and in the vertical direction; if , then the wind direction in the direction of the ship's travel is resistance, and there is no propulsion; If the angle between the water flow direction and the ship's travel direction is , then the current water flow direction is consistent with the forward direction of the hull, and the hull is not subject to water flow resistance, both are propulsion; if , then the current water flow has resistance in the direction perpendicular to the direction of the ship's travel, and there is propulsion in the direction of the ship's travel; if , then the water flow resistance is the resistance in the vertical direction of the hull, and there is no propulsion force; if , then the current water flow direction does not have any propulsion force on the forward movement of the hull, and it is resistance in the direction of the hull's travel and in the vertical direction; if , then the water flow direction is resistance in the direction of the ship's travel, and there is no propulsion; calculate the resistance data of wind direction and water flow direction on the ship's forward movement, among which the total resistance of wind resistance is The calculation formula is ,in, is the air density, is the wind-receiving area of ​​the hull, is the wind resistance coefficient, is the wind speed; the total resistance of water flow resistance The calculation formula is ,in is the density of water, S is the draft area of ​​the hull, is the water flow resistance coefficient, is the water flow velocity; when The actual resistance of the hull is is the component of wind resistance and water flow resistance, and its calculation formula is ; The actual propulsion force on the hull is another component of wind resistance and water flow resistance, and its calculation formula is: ; Since the wind direction generally affects the water flow direction, the wind direction and the water flow direction are normally consistent during the ship's travel, so the wind resistance and water flow resistance on the ship can be superimposed; similarly, the propulsion force on the ship is also the same; if the wind resistance and water resistance on the ship during travel are both the propulsion force of the ship, then , this scenario is a level 3 normal scenario; if the wind resistance and water resistance during the hull's travel have some propulsion force, then , this scenario is a secondary warning scenario; if the wind resistance and water resistance encountered by the ship during its travel are both resistance, then , this scenario is a first-level emergency scenario; because, when the resistance is all propulsion, the ship's driving state is relatively stable and resource consumption is low, it is a third-level normal scenario; when the resistance on the hull is divided into part of the force as resistance and part of the force as propulsion, the hull is still relatively easy in the driving direction, but the resistance in the vertical direction may hinder the hull's driving direction, causing the hull's driving direction to change, which is a second-level warning scenario; when the resistance on the hull is all resistance, the hull is hindered in both the driving direction and the vertical direction. In this case, the hull needs to overcome double resistance at the same time to travel, the hull's running state is not stable, and more resources are consumed, which is a first-level emergency scenario.

Depending on the direction of the resistance, the fuel consumption can be reduced when there is propulsion; The mass of greenhouse gases and harmful substances released by the combustion of unit volume of traditional fuels and LNG fuels in historical data is retrieved. and ; The unit volume is 1 cubic meter; then calculate the total mass of greenhouse gases and harmful substances released by the ship under the corresponding scenario , the calculation formula is ; Import the formula into the coordinate system as a function, and the function can be decomposed into Two linear functions, map the two linear functions in the same coordinate system, map the two linear functions in the same coordinate system, and use the limit method to solve the formula calculate , then Substitution The greenhouse gas and harmful substance emission line segments of the two fuels under the extreme case are obtained respectively, and then the two unconnected points of the two line segments are connected to obtain the actual greenhouse gas and harmful substance emission data value line segment of the dual-fuel mixed combustion, and the value corresponding to the midpoint of the actual dual-fuel mixed combustion greenhouse gas and harmful substance emission data value line segment is taken as , and its corresponding dual fuel consumption is , and its calculation formula is ; Then through the system of equations Calculated The consumption ratio W of LNG and traditional fuel is calculated based on the value of ;in The energy consumption of traditional fuels under extreme conditions. In extreme cases, the consumption of energy supplied by LNG fuel is completely output. is the minimum output value of traditional fuel in actual dual-fuel energy supply, is the maximum output value of LNG fuel in actual dual-fuel energy supply; the calculated amount of the two fuels is the total amount of fuel required for the ship to move forward at this time, and the calculation ratio is to better control the output of the two fuels and meet the current driving demand energy with the minimum pollution production; the limit solution method is to control the consumption of one fuel to 0 and calculate the consumption of the other fuel; S402: The ship driver calculates the optimal output of the dual fuel according to the ship's speed under different scenarios, and performs continuous output of the dual fuel according to the proportional calculation result to regulate the ship's travel.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention utilizes the multi-module function to realize the detection of the environment and the energy consumption and fuel of the hull during the voyage of the dual-fuel bulk carrier, and divides the environment in which the hull is traveling into levels through a comprehensive analysis of wind resistance and water resistance, and provides the best fuel output mode in different level scenarios, and calculates the real-time supply of the dual fuel according to the resistance data, hull energy consumption data and hull driving data in the corresponding environment, and calculates the best fuel ratio, which can achieve the best energy-saving and emission reduction effect while meeting the driving requirements of the hull, and secondly, calculating the best ratio can also help ship managers to better accurately control the continuous fuel supply; the present invention can make up for the risk of switching fuel gaps when the current dual fuels are used alternately, and also supplements the inaccurate fuel ratio existing in the current dual fuel mixed use.
