[0014] [Figure 1] 1 shows a system 1 according to an embodiment. [Figure 2] The operation of device 3 is shown. [Figure 3] 1 shows a system 1A according to a modified example. [Figure 4] 22 illustrates an example computer 2200 in which aspects of the present invention may be embodied, in whole or in part. DETAILED DESCRIPTION OF THE INVENTION

[0015] The present invention will be described below through embodiments of the invention, but the following embodiments do not limit the scope of the invention according to the claims. Furthermore, not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0016] <1. System 1> FIG. 1 shows a system 1 according to this embodiment. The system 1 includes a plurality of generators 2 mounted on a ship (also referred to as the ship itself), and an apparatus 3. The ship itself may be any of a passenger ship, a cargo ship (for example, an LNG tanker or a container ship), a fishing ship (for example, a whaling ship or a trawler), a work boat (for example, a tugboat), a naval vessel, etc. In this embodiment, as an example, the ship itself may be a cargo ship equipped with a crane (not shown).

[0017] <1.1. Generator 2> Each generator 2 generates electricity to be used on the ship and supplies it to each part of the ship. A portion of the electricity generated by each generator 2 may be charged in a storage battery (not shown) and then supplied to each part of the ship, or it may be supplied directly to each part of the ship without going through a storage battery.

[0018] Each generator 2 may be any type of generator. The multiple generators 2 installed on the ship may be of the same type or different types. The operating state of at least some of the multiple generators 2 may be switchable between a power generating state and at least one of a stopped state and a standby state. The power generating state may be a state in which power is being generated, and the stopped state may be a state in which the generator is stopped. The standby state may be a state in which the generator is waiting while reducing fuel consumption so as to transition to the power generating state more quickly than the stopped state. The amount of power generated by at least some of the multiple generators 2 in the power generating state, i.e., the amount of power generated per unit time, may be variable. Each generator 2 may be independently controlled by the device 3.

[0019] <1.2.Device 3> The device 3 controls each generator, and includes an acquisition unit 30 and a control unit 31.

[0020] <1.2.1. Acquisition part 30> The acquisition unit 30 acquires a predicted value of the ship's power consumption. For example, the acquisition unit 30 may acquire a predicted value including the power consumption of a crane mounted on the ship as the predicted value of the ship's power consumption at the scheduled port arrival time. The power consumption may be the amount of power consumed on board the ship per unit time.

[0021] The acquisition unit 30 may acquire a predicted value of the amount of power consumption after a reference time. The reference time may be the time (e.g., 10 minutes) required for the generators 2 to transition from a stopped state to a power generating state. In this embodiment, as an example, the time required for the generators 2 to transition from a stopped state to a power generating state may be the same for each generator 2.

[0022] The acquisition unit 30 may predict the amount of power consumption. The acquisition unit 30 may include a first acquisition unit 301, a model 302, a supply unit 303, and a second acquisition unit 304.

[0023] <1.2.1-1.First acquisition part 301> The first acquisition unit 301 acquires status data indicating the status of the ship. The status data may indicate the current status of power consumption and power generation on the ship.

[0024] The status regarding power consumption may include at least one of the power consumption of each device on board the ship or the overall power consumption of the ship. The status regarding power generation may indicate at least one of the power generation amount of each generator 2, the operating status of each generator 2, or the overall power generation amount of the ship (also referred to as total power generation amount). The power generation amount of each generator 2 may indicate the power generation amount by the generator 2 by associating it with at least the identification information (also referred to as generator ID) of each generator 2 in its power generation status. The operating status of each generator 2 may indicate the operating status of the generator 2 by associating it with the generator ID of each generator 2.

[0025] The status data may further indicate a status that may affect the amount of power consumption, and may indicate, for example, at least one of the current time, the time elapsed since departure from port, the temperature and humidity inside the ship, the environment outside the ship, etc. The environment outside the ship may be at least one of weather (for example, temperature, air pressure, wind direction, wind speed, amount of precipitation (snowfall), etc.) or sea conditions (for example, sea wind, significant wave height, wind waves, ocean currents, etc.).

[0026] The first acquisition unit 301 may acquire the status data from an external device (not shown) of the apparatus 3, for example, from a sensor provided on the ship, from a server on land or the like via a communication device, or from a crew member via an input device. The first acquisition unit 301 may supply the acquired status data to the supply unit 303. The first acquisition unit 301 may supply the status data regarding each generator 2, that is, status data indicating at least one of the power generation amount of each generator 2 and the operating state of each generator 2, to the control unit 31.

[0027] <1.2.1-2. Model 302> The model 302 outputs a predicted value of the amount of power consumption after a reference time (in this embodiment, as an example, the time required for the generator 2 to transition from a stopped state to a power generating state) in response to input of the status data. The model 302 may be generated by a learning process. The learning process of the model 302 may use learning data that associates status data and power consumption obtained from the ship or a ship of the same type as the ship. The learning process may be performed using a known machine learning algorithm such as a neural network, a random forest, gradient boosting, logistic regression, or a support vector machine (SVM).

[0028] <1.2.1-3. Supply section 303> The supply unit 303 supplies the state data acquired by the first acquisition unit 301 to the model 302. As a result, the model 302 outputs a predicted value of the amount of power consumption.

[0029] <1.2.1-4.Second acquisition part 304> The second acquisition unit 304 acquires, as a predicted value of power consumption after a reference time, a predicted value of power consumption output from the model 302 in response to the supply unit 303 supplying the status data to the model 302. The second acquisition unit 304 may supply the acquired predicted value of power consumption to the control unit 31.

[0030] <1.2.2. Control unit 31> The control unit 31 controls each of the multiple generators 2 installed on the ship so that the amount of power generated by each of the generators 2 is within a reference range of the predicted value of power consumption acquired by the acquisition unit 30. The amount of power generated by the multiple generators 2 may be the total amount of power generated by the ship. The control unit 31 may control the total amount of power generated at a time predicted by the predicted value (for example, in this embodiment, a time a reference time later than the present) so that it is within a reference range of the predicted value of power consumption. The reference range may be any range, and may, for example, be a range whose lower limit is a value obtained by subtracting a reference fluctuation amount of power consumption from the predicted value of power consumption and whose upper limit is a value obtained by adding the reference fluctuation amount of power consumption to the predicted value of power consumption. The reference fluctuation amount may be the maximum amount of power consumption that can fluctuate within a reference time (for example, in this embodiment, the time required for the generator 2 to transition from a stopped state to a power generating state).

[0031] The control unit 31 may increase or decrease the total amount of power generation by transitioning the operating state of at least some of the generators 2 (in the present embodiment, as an example, each generator 2) among the multiple generators 2 between a stopped state and a power generating state. The control unit 31 may increase or decrease the amount of power generation of the generators 2 in the power generating state.

[0032] The control unit 31 may control each generator 2 based on the status data related to the generator 2 supplied from the first acquisition unit 301. For example, the control unit 31 may increase the amount of power generated by at least one generator 2 in a power generating state, or may transition at least one generator 2 in a standby state or a stopped state to a power generating state, in response to the current total amount of power generated being lower than the lower limit of the reference range. The control unit 31 may decrease the amount of power generated by at least one generator 2 in a power generating state, or may transition at least one generator 2 in a power generating state to a standby state or a stopped state, in response to the current total amount of power generated being higher than the upper limit of the reference range. The control unit 31 may maintain the state of each generator 2 in response to the current total amount of power generated being within the reference range.

[0033] The control unit 31 may store the rated output of each generator 2 and may control each generator 2 based on the rated output of the generator 2 currently in a power generating state. For example, the control unit 31 may transition at least one generator 2 in a standby state or a stopped state among the multiple generators 2 to a power generating state when the predicted power consumption value acquired by the acquisition unit 30 is greater than the rated output of each generator 2 currently in a power generating state. The rated output may be the maximum amount of power that can be stably output continuously. The control unit 31 may add the generators 2 in a standby state or a stopped state to the operating state transition candidates one by one, calculate the sum of the rated outputs of the transition candidate generators 2 and the sum of the rated outputs of the generators 2 already in a power generating state, and transition each of the transition candidate generators 2 to a power generating state when the sum exceeds the predicted power consumption value. The order of the generators 2 added to the transition candidate generators may be in descending order of rated output or in descending order. The order of the generators 2 added to the transition candidate generators may be in descending order of the total time that the generators 2 have been in a power generating state or in descending order. The order in which the generators 2 are added to the transfer candidates may be random.

[0034] According to the above-mentioned device 3, each generator 2 is controlled so that the amount of power generated by the multiple generators 2 falls within a standard range based on the predicted value of power consumption, thereby preventing power outages on the ship due to insufficient power generation and preventing fuel waste due to excessive power generation.

[0035] In addition, a predicted value that includes the power consumption of the crane installed on the ship is obtained as the predicted value of the ship's power consumption at the scheduled time of arrival, so that power can be secured to use the crane for loading or unloading, making work more efficient after arrival.

[0036] Furthermore, since a predicted value of the amount of power consumption after a reference time required for the generator 2 to transition from a stopped state to a power generating state is obtained, even if the generator is in a standby state or a stopped state, the generator 2 can be transitioned to a power generating state in accordance with the predicted amount of power consumption. Therefore, power outages due to power shortages can be reliably prevented.

[0037] Furthermore, in response to the predicted power consumption being greater than the rated output of each generator 2 currently in a power generating state, at least one generator 2 among the multiple generators 2 that is in a standby state or stopped state is transitioned to a power generating state, thereby reliably preventing power outages due to power shortages.

[0038] Furthermore, in response to status data indicating the state of the ship being supplied to the model 302, a predicted value of power consumption output from the model 302 is acquired as a predicted value of power consumption after a reference time. Therefore, by supplying status data indicating the state of the ship to the model 302, a predicted value of power consumption according to the state of the ship can be acquired.

[0039] <2. Operation> 2 shows the operation of the device 3. The device 3 may control each generator 2 by performing the processes of steps S11 to S19.

[0040] In step S11, the first acquisition unit 301 acquires status data indicating the status of the ship, and in step S13, the supply unit 303 supplies the acquired status data to the model 302. As a result, in step S15, the model 302 predicts the power consumption of the ship. The model 302 may predict the power consumption after a reference time based on the status indicated by the status data.

[0041] In step S17, the second acquisition unit 304 acquires the predicted value of the power consumption output from the model 302. Then, in step S19, the control unit 31 controls each of the multiple power generators 2 so that the amount of power generated by each of the power generators 2 falls within a reference range based on the predicted value of the power consumption acquired in step S17. When the processing of step S19 is completed, the processing may proceed to step S11.

[0042] <3. Modifications> Fig. 3 shows a system 1A according to a modified example. Components that are substantially the same as those in the system 1 shown in Fig. 1 are given the same reference numerals, and descriptions thereof will be omitted.

[0043] The device 3A of the system 1A acquires predicted values ​​of power consumption in a manner different from that of the system 1 in the above embodiment. The device 3A includes a storage unit 33A, an acquisition unit 30A, and a control unit 31A.

[0044] The memory unit 33A stores in advance predicted values ​​of the ship's power consumption at multiple times. The multiple times for which power consumption is stored may be set in advance within a period ranging from the ship's scheduled departure time to the ship's scheduled arrival time. For example, if the ship is scheduled to depart at 9:00 on January 1st and arrive at port at 21:00 on January 3rd, the multiple times may be set for each reference time (in this modified example, the time required for the generator 2 to transition from a stopped state to a power generating state) within the period from 9:00 on January 1st to 21:00 on January 3rd. Alternatively, the multiple times may be set in advance within a period of one day. For example, the multiple times may be set for each reference time within the period from 0:00 to 24:00. The predicted value of power consumption at each time may be calculated from the power consumption for each time during past voyages.

[0045] The acquisition unit 30A reads out from the storage unit 33A the predicted value of power consumption after a reference time from the current time. This acquires the predicted value of power consumption after the reference time. The acquisition unit 30A may acquire the current time from an external clock device (not shown) or the like, and may read out from the storage unit 33A the predicted value of power consumption associated with the acquired current time. The acquisition unit 30A may supply the read predicted value to the control unit 31.

[0046] The control unit 31A controls each of the multiple generators 2 installed on the ship so that the amount of power generated by each generator 2 falls within a reference range based on the predicted value of power consumption acquired by the acquisition unit 30A. The control unit 31A may differ from the control unit 31 in the above embodiment in that it acquires status data related to the generators 2 from outside the device 3A.

[0047] According to the above-mentioned device 3A, predicted values ​​of the ship's power consumption at multiple times are stored in advance, and the predicted value of power consumption from the current time to a reference time is read out, thereby simplifying the configuration for obtaining the predicted value of power consumption.

[0048] In addition, since the multiple times at which predicted power consumption values ​​are stored are set in advance within the period from the ship's scheduled departure time to the scheduled arrival time, predicted power consumption values ​​can be obtained that match the ship's condition at each time from departure to arrival.

[0049] In addition, since multiple times at which predicted power consumption values ​​are stored are set in advance within a one-day period, predicted power consumption values ​​can be obtained that are tailored to the state of the ship at each time within a one-day cycle.

[0050] In the above modification, the device 3A is described as having a memory unit 33A, but this is not necessary. In this case, the device 3A may be externally connected to a memory device that stores in advance predicted values ​​of the ship's power consumption at multiple times. The acquisition unit 30A may read the predicted values ​​of power consumption from the memory device.

[0051] <4. Other Modifications> In the above embodiment and modified example, the time required for each generator 2 to transition from a stopped state to a power generating state has been described as the same, but the time may be different. In this case, the acquisition unit 30, 30A may use a different time as the reference time depending on the generator 2 to be transitioned from a stopped state to a power generating state, and acquire a predicted value of the power consumption after the reference time. As an example, in response to being supplied with status data including the generator ID of the stopped generator 2, the acquisition unit 30, 30A may use the time required for the stopped generator 2 to transition to a power generating state as the reference time. When multiple generators 2 are stopped, the acquisition unit 30, 30A may use the longest time among the multiple times required for each generator 2 to transition to a power generating state as the reference time.

[0052] Furthermore, the reference time has been described as the time required for the generator 2 to transition from a stopped state to a power generating state, but it may also be the time required for the generator 2 to transition from a standby state to a power generating state.

[0053] Various embodiments of the present invention may also be described with reference to flowcharts and block diagrams, where the blocks may represent (1) stages of a process in which operations are performed or (2) sections of an apparatus responsible for performing the operations.

[0056] The computer-readable instructions may be provided to a processor or programmable circuitry of a general-purpose computer, special-purpose computer, or other programmable data processing apparatus, either locally or over a wide-area network (WAN) such as a local area network (LAN), the Internet, etc., which executes the computer-readable instructions to create means for performing the operations specified in the flowcharts or block diagrams. Examples of processors include computer processors, processing units, microprocessors, digital signal processors, controllers, microcontrollers, etc.

[0057] 4 illustrates an example of a computer 2200 in which aspects of the present invention may be embodied, in whole or in part. Programs installed on the computer 2200 may cause the computer 2200 to function as or perform operations associated with an apparatus or one or more sections of the apparatus according to embodiments of the present invention, and / or to perform a process or steps of a process according to embodiments of the present invention. Such programs may be executed by the CPU 2212 to cause the computer 2200 to perform specific operations associated with some or all of the blocks of the flowcharts and block diagrams described herein.

[0058] A computer 2200 according to this embodiment includes a CPU 2212, a RAM 2214, a graphics controller 2216, and a display device 2218, which are interconnected by a host controller 2210. The computer 2200 also includes input / output units such as a communication interface 2222, a hard disk drive 2224, a DVD-ROM drive 2226, and an IC card drive, which are connected to the host controller 2210 via an input / output controller 2220. The computer also includes legacy input / output units such as a ROM 2230 and a keyboard 2242, which are connected to the input / output controller 2220 via an input / output chip 2240.

[0059] The CPU 2212 operates according to programs stored in the ROM 2230 and RAM 2214, thereby controlling each unit. The graphics controller 2216 acquires image data generated by the CPU 2212 into a frame buffer or the like provided in the RAM 2214 or into the graphics controller 2216 itself, and causes the image data to be displayed on the display device 2218.

[0060] The communication interface 2222 communicates with other electronic devices via a network. The hard disk drive 2224 stores programs and data used by the CPU 2212 in the computer 2200. The DVD-ROM drive 2226 reads programs or data from the DVD-ROM 2201 and provides the programs or data to the hard disk drive 2224 via the RAM 2214. The IC card drive reads programs and data from an IC card and / or writes programs and data to an IC card.

[0061] The ROM 2230 stores therein a boot program or the like that is executed by the computer 2200 upon activation, and / or programs that depend on the hardware of the computer 2200. The input / output chip 2240 may also connect various input / output units to the input / output controller 2220 via a parallel port, a serial port, a keyboard port, a mouse port, etc.

[0062] The programs are provided by a computer-readable medium such as a DVD-ROM 2201 or an IC card. The programs are read from the computer-readable medium, installed in the hard disk drive 2224, RAM 2214, or ROM 2230, which are also examples of computer-readable media, and executed by the CPU 2212. Information processing described in these programs is read by the computer 2200, and brings about cooperation between the programs and the various types of hardware resources described above. An apparatus or method may be configured by realizing information manipulation or processing in accordance with the use of the computer 2200.

[0063] For example, when communication is performed between the computer 2200 and an external device, the CPU 2212 may execute a communication program loaded into the RAM 2214 and instruct the communication interface 2222 to perform communication processing based on the processing described in the communication program. Under the control of the CPU 2212, the communication interface 2222 reads transmission data stored in a transmission buffer processing area provided in the RAM 2214, the hard disk drive 2224, the DVD-ROM 2201, or a recording medium such as an IC card, and transmits the read transmission data to the network, or writes reception data received from the network to a reception buffer processing area or the like provided on the recording medium.

[0064] The CPU 2212 may also cause all or a necessary portion of a file or database stored on an external recording medium such as the hard disk drive 2224, the DVD-ROM drive 2226 (DVD-ROM 2201), an IC card, etc. to be read into the RAM 2214, and perform various types of processing on the data on the RAM 2214. The CPU 2212 then writes back the processed data to the external recording medium.

[0065] Various types of information, such as various types of programs, data, tables, and databases, may be stored on the recording medium and may undergo information processing. The CPU 2212 may perform various types of processing on data read from the RAM 2214, including various types of operations, information processing, conditional judgment, conditional branching, unconditional branching, information search / replacement, etc., as described throughout this disclosure and specified by the instruction sequences of the programs, and write the results back to the RAM 2214. The CPU 2212 may also search for information in a file, database, etc. on the recording medium. For example, if multiple entries each having an attribute value of a first attribute associated with an attribute value of a second attribute are stored on the recording medium, the CPU 2212 may search for an entry that matches a condition specified by the attribute value of the first attribute from among the multiple entries, read the attribute value of the second attribute stored in the entry, and thereby obtain the attribute value of the second attribute associated with the first attribute that satisfies a predetermined condition.

[0066] The above-described programs or software modules may be stored in a computer-readable medium on or near the computer 2200. A recording medium such as a hard disk or RAM provided in a server system connected to a dedicated communication network or the Internet can also be used as a computer-readable medium, thereby providing the programs to the computer 2200 via the network.

[0067] Although the present invention has been described above using embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments. It will be apparent to those skilled in the art that various modifications and improvements can be made to the above embodiments. It is clear from the claims that such modifications and improvements can also be included within the technical scope of the present invention.

[0068] It should be noted that the execution order of each process, such as operations, procedures, steps, and stages, in the devices, systems, programs, and methods shown in the claims, specifications, and drawings is not specifically stated as "before," "prior to," etc., and that the processes can be performed in any order unless the output of a previous process is used in a subsequent process. Even if the operational flow in the claims, specifications, and drawings is described using "first," "next," etc. for convenience, this does not mean that the processes must be performed in this order.
