Description
Technical Field
The present invention relates to a fuel supply control device, a fuel supply control method, and a recording medium having a fuel supply control program recorded thereon.
Background
In recent years, there has been a development of automatic driving for automatically navigating a ship on a predetermined route. During a normal voyage including automatic driving, automatic control of the fuel supply amount according to the load of the power plant is performed so as to keep the rotation speed of the power plant constant (for example, see patent document 1).

Disclosure of Invention
Problems to be solved by the invention
A power plant of a ship is generally widely controlled to keep a constant rotation speed. For example, when the rudder turns, the resistance of the rudder or the entire hull to water increases. As a result, the load on the power plant increases and the rotational speed decreases. Therefore, control is performed to increase the amount of fuel supplied to the power plant during steering. The output of the power unit is thereby increased and the rotational speed is kept constant.
Hereinafter, the angle with respect to the center position of the rudder when steering the ship is referred to as "rudder angle". In general, the steering of a ship is performed for the purpose of changing the heading direction for traveling on a determined route, or temporarily for the purpose of correcting a deviation from the correct heading direction due to a tidal current, wind, or the like. The latter has the following features compared to the former: (1) the rudder angle is small; (2) the steering time is short; (3) the change speed of the rudder angle is high; (4) the steering and return steering are repeated periodically. The latter, that is, the temporary steering for returning to the correct heading direction by correcting the deviation of the ship from the correct heading direction, is hereinafter referred to as "steering".
Since the rudder press has the above-described feature, the rotation speed of the power unit does not significantly decrease even if the rudder press is performed. In addition, even if the rotational speed of the power unit decreases, the recovery is performed in a relatively short time. Therefore, even if an increase in the amount of fuel supplied to the rudder press is suppressed, the efficiency of the power plant is not greatly affected. In contrast, if the fuel supply amount is increased more than necessary every time the rudder press is switched, the fuel consumption rate is rather decreased.
The engine control device described in patent document 1 predicts a variation in the rotation speed of the power plant based on information on the steering angle, and corrects the fuel supply amount to prevent the variation in the rotation speed. However, in this technique, control is not performed to adjust the fuel supply amount based on whether or not it is rudder control.
The present invention has been made in view of the above problems, and an object thereof is to improve fuel consumption of a ship.
Means for solving the problems
In order to solve the above problem, a fuel supply control device according to an aspect of the present invention includes: a press steering determination unit that determines whether steering is press steering based on at least one of steering angle information of the ship and a fuel supply amount to the power plant; and a fuel supply control unit that, when the steering pressure determination unit determines that the steering is the steering pressure, suppresses a variation in the fuel supply amount as compared to a case where the steering pressure is not determined. Here, the increase or decrease in the amount of fuel supply occurring from the start of steering until the ship returns to the correct heading direction is referred to as "variation in the amount of fuel supply" (the same applies hereinafter).
Another embodiment of the present invention is a fuel supply control method. The method comprises the following steps: a press steering determination step of determining whether or not steering is press steering based on at least one of steering angle information of the ship and a fuel supply amount to the power plant; and a fuel supply control step of, when it is determined that the steering is press steering, suppressing variation in the fuel supply amount as compared with a case where the steering is not press steering.
Still another embodiment of the present invention is a recording medium on which a fuel supply control program is recorded. The program causes a computer to execute fuel supply control including: a press steering determination step of determining whether steering is press steering based on information including steering angle information of the ship and a fuel supply amount to the power plant; and a fuel supply control step of, when it is determined that the steering is press steering, suppressing variation in the fuel supply amount as compared with a case where the steering is not press steering.
In addition, any combination of the above-described constituent elements or a mode in which constituent elements or expressions of the present invention are substituted for each other among a method, an apparatus, a system, and the like is also effective as a mode of the present invention.

Detailed Description
The present invention will be described below based on preferred embodiments with reference to the accompanying drawings. The same or equivalent components, members and processes shown in the respective drawings are denoted by the same reference numerals, and overlapping descriptions are appropriately omitted.
[ first embodiment ]
Fig. 1 is a block diagram showing the configuration of a fuel supply control device 1 according to a first embodiment of the present invention. The fuel supply control device 1 is connected to a control target 12 such as a fuel injection system or a power plant. The fuel supply control device 1 includes a rudder press determination unit 10 and a fuel supply control unit 11.
Hereinafter, information on the steering angle, for example, the magnitude of the steering angle, the steering time, the speed of change of the steering angle, the periodic change of the steering angle, and the like will be referred to as "steering angle information". The rudder angle information and the fuel supply amount to the control target 12 are input to the rudder press deciding unit 10.
The press steering determination unit 10 determines whether or not the steering is press steering based on at least one of the input steering angle information and the fuel supply amount to the control target 12. The rudder press determination unit 10 outputs the determination result to the fuel supply control unit 11.
For example, the press steering determination unit 10 determines that the steering is press steering when: (1) the size of the rudder angle is smaller than a specified value; (2) the time to steer is shorter than a prescribed value; (3) the speed of change of the rudder angle is faster than a prescribed value; (4) the rudder angle is periodically changed more than a predetermined number of times.
When the steering is a press steering, the variation in the amount of fuel supply by the fuel supply control is relatively small. Therefore, the press steering determination unit 10 can determine that the steering is the press steering even when the variation in the fuel supply amount is smaller than the predetermined value.
Hereinafter, the preset rotation speed of the power unit is referred to as a "set rotation speed", the actual rotation speed of the power unit is referred to as an "actual rotation speed", and the difference between the set rotation speed and the actual rotation speed is referred to as a "rotation speed deviation". The determination result of the rudder pressure determining unit 10 and the rotation speed deviation are input to the fuel supply control unit 11. The fuel supply control unit 11 determines the fuel supply amount based on the rotational speed deviation and the determination result from the rudder press determination unit 10. Specifically, the fuel supply control unit 11 determines the fuel supply amount so that the absolute value of the rotational speed deviation is reduced by varying the fuel supply amount. The fuel supply control unit 11 outputs the determined fuel supply amount to the control target 12.
Here, when the determination result input from the rudder suppression determination unit 10 is rudder suppression, the fuel supply control unit 11 suppresses the variation in the fuel supply amount as compared with the case where the rudder suppression is not performed. For example, when the fuel supply amount is controlled by PID Control (Proportional-Integral-Derivative Control), the fuel supply Control unit 11 reduces the gain of the PID Control as compared with the case where the steering is not performed, thereby suppressing the variation in the fuel supply amount.
The control target 12 operates at the actual rotation speed in accordance with the fuel supply amount input from the fuel supply control unit 11. The control target 12 feeds back the actual rotation speed to the input side of the fuel supply control portion 11. The rotation speed deviation is obtained by subtracting the fed-back actual rotation speed from the set rotation speed. As described above, the rotational speed deviation is input to the fuel supply control unit 11.
According to the present embodiment, since fluctuations in the amount of fuel supply are suppressed when steering is pressure steering, the fuel consumption rate of the ship can be improved.
[ second embodiment ]
Fig. 1 is a block diagram showing a configuration of a fuel supply control device 1 according to a second embodiment of the present invention. When the steering determination unit 10 determines that the steering is the steered steering, the fuel supply control unit 11 of the fuel supply control device 1 of the second embodiment strongly suppresses the increase in the fuel supply amount as the steering angle is smaller. The other configurations and operations are common to those of the fuel supply control device 1 of the first embodiment. For example, in the case of performing the control of the fuel supply amount by the PID control, the fuel supply control unit 11 strongly suppresses the variation of the fuel supply amount by reducing the gain of the PID control more greatly than the case of steering by a large steering angle.
The smaller the rudder angle at the time of steering, the smaller the load on the power plant. Therefore, even if the variation in the fuel supply amount is more strongly suppressed when the steering angle is small, the efficiency of the power plant is not greatly affected. In this case, the fuel consumption rate is reduced more greatly by suppressing the variation in the fuel supply amount more strongly.
According to the present embodiment, since the fuel supply control is performed more precisely when the steering is the press steering, the fuel consumption rate of the ship can be further improved.
[ third embodiment ]
Fig. 2 is a block diagram showing the configuration of a fuel supply control device 2 according to a third embodiment of the present invention. The fuel supply control device 2 includes an operation condition determination unit 13 in addition to the configuration of the fuel supply control device 1 shown in fig. 1.
The rudder angle information and the fuel supply amount to the control target 12 are input to the rudder press deciding unit 10. The press steering determination unit 10 determines whether or not the steering is press steering based on at least one of the input steering angle information and the fuel supply amount to the control target 12. The rudder press determination unit 10 outputs the determination result to the fuel supply control unit 11.
The set rotation speed, the rotation speed deviation, and the fuel supply amount to the control target 12 are input to the operating condition determination unit 13. The operating condition determining unit 13 determines whether or not at least one of the set rotation speed, the actual rotation speed, the rotation speed deviation, and the fuel supply amount satisfies a predetermined condition. The operating condition determining portion 13 outputs the determination result to the fuel supply control portion 11.
For safety reasons, it is preferable that the power plant of the ship operates at a fixed rotation speed or more. Therefore, it is preferable that, when the set rotation speed or the actual rotation speed is smaller than a predetermined value, control in the direction of increasing the fuel supply amount is not inhibited even if steering is press steering. Therefore, for example, when the set rotation speed or the actual rotation speed is equal to or greater than a predetermined value, the operation condition determination unit 13 determines that the predetermined condition is satisfied.
It is undesirable that the actual rotational speed deviates greatly from the set rotational speed in view of sailing. That is, the absolute value of the rotational speed deviation is preferably a fixed value or less. Therefore, it is preferable that, when the absolute value of the rotation speed deviation is larger than a predetermined value, the control in the direction of increasing the fuel supply amount is not inhibited even if the steering is the press steering. Therefore, for example, when the absolute value of the rotation speed deviation is equal to or less than a predetermined value, the operation condition determination unit 13 determines that the predetermined condition is satisfied.
The fuel supply control unit 11 receives the rotation speed deviation, the judgment result of the rudder pressure judging unit 10, and the judgment result of the operating condition judging unit 13. The fuel supply control unit 11 determines the fuel supply amount based on the rotation speed deviation, the determination result from the rudder control determining unit 10, and the determination result from the operating condition determining unit 13. Specifically, the fuel supply control unit 11 determines the fuel supply amount so as to reduce the absolute value of the rotational speed deviation by varying the fuel supply amount. The fuel supply control unit 11 outputs the determined fuel supply amount to the control target 12.
Here, the fuel supply control unit 11 suppresses the variation in the fuel supply amount as compared with the case where the steering is not performed, only when the steering pressure determination unit 10 determines that the steering is the steering pressure and the operation condition determination unit 13 determines that the predetermined condition is satisfied.
According to the present embodiment, since the operating condition determining unit 13 determines the appropriate operation, the fuel consumption rate of the ship can be improved without hindering safety or navigation.
[ fourth embodiment ]
Fig. 2 is a block diagram showing the configuration of a fuel supply control device 2 according to a fourth embodiment of the present invention. The operating condition determining unit 13 of the fuel supply control device 2 according to the fourth embodiment determines that the predetermined condition is satisfied only when the actual rotation speed decreases and the fuel supply amount increases. The other configurations and operations are common to those of the fuel supply control device 2 according to the third embodiment.
As described above, the fuel supply control unit 11 determines the fuel supply amount so as to reduce the absolute value of the rotational speed deviation by varying the fuel supply amount. For example, when the actual rotation speed is reduced, the load of the power plant is increased, and therefore the fuel supply control portion 11 performs control for increasing the fuel supply amount. In contrast, since the load of the power plant is reduced when the actual rotation speed is increased, the fuel supply control portion 11 performs control to reduce the fuel supply amount.
When the steering is the press steering, the control for suppressing the increase in the fuel supply amount is preferable because the fuel consumption rate is increased. In contrast, control to suppress the fuel supply amount in the direction of decreasing the fuel supply amount is undesirable because it adversely causes deterioration in the fuel consumption rate.
According to the present embodiment, since the determination criterion of the operating condition determining unit 13 is appropriately determined, the fuel consumption rate of the ship can be more reliably improved.
[ fifth embodiment ]
Fig. 3 is a flowchart of a fuel supply control method according to a fifth embodiment. The method includes a rudder press determining step S1 and a fuel supply control step S2.
In the press steering determination step S1, the method determines whether or not the steering is press steering based on at least one of the steering angle information of the ship and the fuel supply amount to the power plant.
For example, in the press-steering determination step S1, it is determined that the steering is press-steering in the following cases: (1) the size of the rudder angle is smaller than a specified value; (2) the time to steer is shorter than a prescribed value; (3) the speed of change of the rudder angle is faster than a prescribed value; (4) the rudder angle is periodically changed more than a predetermined number of times.
When the steering is the press steering, the variation in the amount of fuel supply by the fuel supply control is relatively small. Therefore, in the press-steering determination step S1, for example, when the variation in the fuel supply amount is smaller than a predetermined value, it may be determined that the steering is press-steering.
In the case where the determination result in the rudder press determining step S1 is affirmative, the process proceeds to a fuel supply control step S2. On the other hand, if the determination result in the steering depression determination step S1 is negative, the flow ends and the normal fuel supply control is continued.
In the fuel supply control step S2, the method suppresses the variation in the fuel supply amount as compared with the case where the rudder control is not performed. For example, when the fuel supply amount is controlled by the PID control, the gain of the PID control is reduced in the fuel supply control step S2 as compared with the case where the steering is not performed, thereby suppressing the variation in the fuel supply amount.
According to the present embodiment, since fluctuations in the amount of fuel supply are suppressed when steering is pressure steering, the fuel consumption rate of the ship can be improved.
[ sixth embodiment ]
Fig. 4 is a flowchart of a fuel supply control method according to a sixth embodiment. The present method includes an operating condition determining step S3 in addition to the fuel supply control method of the fifth embodiment.
In the press steering determination step S1, the method determines whether or not the steering is press steering based on at least one of the steering angle information of the ship and the fuel supply amount to the power plant.
If the determination result in the steering depression determination step S1 is affirmative, the process proceeds to an operation condition determination step S3. On the other hand, if the determination result in the steering depression determination step S1 is negative, the flow ends and the normal fuel supply control is continued.
In the operation condition determination step S3, the method determines whether or not at least one of the set rotation speed, the actual rotation speed, the rotation speed deviation, and the fuel supply amount satisfies a predetermined condition. For example, when the set rotation speed or the actual rotation speed is equal to or greater than a predetermined value, it is determined that the predetermined condition is satisfied. For example, when the absolute value of the rotational speed deviation is equal to or less than a predetermined value, it is determined that the predetermined condition is satisfied.
In the case where the determination result in the operating condition determining step S3 is affirmative, the process shifts to a fuel supply control step S2. On the other hand, if the determination result in the operating condition determination step S3 is negative, the flow ends and the normal fuel supply control is continued.
In the fuel supply control step S2, the method suppresses the variation in the fuel supply amount as compared with the case where the rudder control is not performed.
According to the present embodiment, since the proper operation determination is performed in the operation condition determination step S3, the fuel consumption rate of the ship can be improved without hindering safety or navigation.
The present invention has been described above based on several embodiments. It will be understood by those skilled in the art that these embodiments are illustrative, and various changes and modifications can be made within the scope of the claims of the present invention, and that such changes and modifications are also within the scope of the claims of the present invention. Accordingly, the description and drawings in this specification are to be regarded in an illustrative rather than a restrictive sense. In particular, the above-described embodiment has been described mainly as an application example to an automatically steered ship, but the present invention is not limited to this, and can be widely applied to a manually steered ship, for example.
[ seventh embodiment ]
The seventh embodiment is a recording medium on which a fuel supply control program is recorded. The program causes a computer to execute the fuel supply control of the fifth embodiment. The specific fuel control is the same as that described in the fifth embodiment, and therefore, a detailed description thereof is omitted.
According to the present embodiment, a program for improving the fuel consumption rate of a ship can be installed in computer software.
[ eighth embodiment ]
The eighth embodiment is also a recording medium on which a fuel supply control program is recorded. The program causes a computer to execute the fuel supply control of the sixth embodiment. The specific fuel control is the same as that described in the sixth embodiment, and therefore, a detailed description thereof is omitted.
According to the present embodiment, a program for improving the fuel consumption rate of a ship without interfering with safety or navigation can be installed in computer software.
Next, a modified example will be explained. In the description of the modified examples, the same or equivalent constituent elements and members as those of the embodiment are denoted by the same reference numerals. The description overlapping with the embodiment is appropriately omitted, and the description is repeated for the configuration different from the embodiment.
[ modification 1]
In the third embodiment, a state in which the predetermined condition is satisfied and the control for suppressing the variation in the fuel supply amount is performed is referred to as a "rudder-pressing mode", and a state in which the predetermined condition is not satisfied is referred to as a "non-rudder-pressing mode". The operating condition determining unit 13 may determine to shift from the non-steered system mode to the steered system mode based on at least one of the past fuel injection mode, the periodic change in the steering angle, the set rotation speed, the rotation speed deviation, and the fuel supply amount. On the other hand, the operating condition determining unit 13 may determine that the steering mode is to be switched to the non-steering mode based on at least one of the rotation speed deviation, the magnitude of the steering angle, and the change speed of the steering angle. According to the present modification, the criteria for determining the transition from the non-steered mode to the steered mode and the transition from the steered mode to the non-steered mode can be clarified.
[ modification 2]
When the steering pressure determination unit 10 determines that the steering is the steering pressure, and the actual rotation speed increases and the fuel supply amount decreases, the fuel supply control unit 11 may promote the variation in the fuel supply amount. Since the load on the power plant is reduced when the actual rotation speed increases, the fuel supply control unit 11 performs control for reducing the fuel supply amount. According to the present modification, the fuel consumption rate can be further improved by suppressing the fuel amount supply when it is determined that the steering is being pressed when the rotation speed decreases and the fuel supply amount is in the increasing direction.
Any combination of the above-described embodiments and modifications is also useful as an embodiment of the present invention. The new embodiment resulting from the combination has the respective effects of the combined embodiments and modified examples.
