JP 2016-120767 A

  Here, the need for providing information indicating the operating state of the ship to the user is increasing. Therefore, it is conceivable to display the graph created in Patent Document 1 as described above to the user. However, the operational state of the ship varies depending on the sea state during the operation of the ship (the state of the sea that affects the speed of the ship). Therefore, the user may not be able to correctly grasp the state of the ship simply by displaying the detected operating state of the ship to the user. That is, it has been demanded to increase the value of ship information provided to the user.

  The present invention has been made to solve such a problem, and can provide a ship information providing device, a ship information providing program, a storage medium, a ship information providing method, and a ship information providing apparatus that can increase the value of ship information provided to a user. And a ship information providing system.

  The ship information providing apparatus according to the present invention is a ship information providing apparatus that provides information related to a ship, and obtains ship information including at least operation information relating to the operation of the ship and sea state information relating to the sea state during operation of the ship.

  In this ship information providing device, the information classification unit divides the sea state into a plurality of sea state ranks based on the sea state information, and separates the operation information for each sea state rank. Therefore, the information classification unit considers the sea conditions that affect the operational state of the ship, sets the sea state rank ranked based on the magnitude of the influence of the sea state, and then sets the operation information for each sea state rung.

  In the ship information providing device, the adjustment unit creates a first approximate line for each sea rank for a graph in which the relationship between the first parameter and the second parameter of the operation information is plotted. The second approximate line may be created for each sea rank by adjusting the first approximate line based on the relationship with the first approximate line. For example, when the number of plots for a certain sea state rank is too small, the accuracy of the information indicated by the first approximate line decreases. On the other hand, the adjustment unit creates the second approximate line by adjusting the first approximate line based on the relationship with the first approximate line of another sea state rank. The second approximate line is an approximate line that reflects the overall tendency in consideration of approximate lines of other marine ranks. Therefore, the user can confirm more accurate information that is physically consistent.

  In the ship information providing device, the adjustment unit extracts the coefficient of the approximate expression of the first approximate line created for each sea state rank, smoothes and adjusts the coefficient based on the relationship with the coefficient of the other sea state rank, The second approximate line may be created by introducing the adjusted coefficient into the approximate expression.

Alternatively, the transmission / reception unit 12 may transmit the ship information acquired by the information acquisition unit 11 to the server 20 when the ship information is accumulated to some extent. For example, the transmission / reception unit 12 may transmit information to the server 20 during a predetermined time of the day. Moreover, the transmission / reception part 12 may transmit information every hour. However, the transmission timing of the transmission / reception unit 12 is not particularly limited. Moreover, the transmission / reception part 12 receives the information which shows the relationship between the sea state of the own ship and other several ship, and an operation state.

  The user terminal 30 is a terminal that a user who uses a service provided by the ship information providing system 100 according to the present embodiment has. The user terminal 30 may be a terminal installed in an onshore building or the like instead of the ship 40. The user terminal 30 includes a processor, a memory, a storage, a communication interface, and a user interface, similar to the ship control unit 10 described above. The processor controls the memory, storage, communication interface, and user interface, and realizes the function of the user terminal 30 described later. The user terminal 30 may be composed of a plurality of computers.

  The user terminal 30 includes an information acquisition unit 31, a display unit 32, an information input unit 33, and a transmission / reception unit 34.

  The information acquisition unit 31 acquires display information provided from the server 20 via communication from the server 20. The information acquisition unit 31 acquires driving information (details will be described later) whose display mode has been adjusted by the adjustment unit 23 of the server 20. The information acquisition unit 31 also acquires other information from the server 20 via communication.

  The transmission / reception unit 34 transmits / receives various information to / from the server 20. The transmission / reception unit 34 transmits / receives various information to / from the server 20 via wired / wireless communication via the Internet.

  The administrator terminal 60 is a terminal owned by an administrator who manages services provided by the ship information providing system 100 according to the present embodiment. The manager terminal 60 may be a terminal installed in a land building or the like instead of the ship 40. The administrator terminal 60 includes an information acquisition unit 61, a display unit 62, an information input unit 63, and a transmission / reception unit 64. These components include the information acquisition unit 31, the display unit 32, the information input unit 33, and the transmission / reception unit 34 of the user terminal 30, which have the same concept.

  The server 20 includes a processor, a memory, a storage, a communication interface, and a user interface, similar to the ship control unit 10 described above. The processor controls the memory, storage, communication interface, and user interface, and realizes the function of the server 20 described later. The server 20 may be composed of a plurality of computers. The server 20 may be a cloud server.

  The server 20 includes an information acquisition unit 21, an information separation unit 22, an adjustment unit 23, a transmission / reception unit 24, and a storage unit 26. In the present embodiment, the server 20 includes a ship information providing device 150 that includes an information acquisition unit 21, an information sorting unit 22, an adjustment unit 23, and a transmission / reception unit 24.

  The information acquisition unit 21 acquires ship information including at least operation information and sea state information of the ship 40 from a plurality of ships 40 via communication. The information acquisition unit 21 also acquires other information from the plurality of ships 40 via communication. The information acquisition unit 21 can acquire various types of information acquired by the information acquisition unit 11 of the ship control unit 10. If the information acquisition part 21 acquires ship information from each ship 40, it will transmit the said information to the memory | storage part 26, and will store it. The storage unit 26 stores driving information and sea state information in association with each other at each information acquisition time. For example, as shown in FIG. 3, the storage unit 26 stores information acquisition time when information is acquired and “wind speed”, “(ship) speed”, “(main) associated with the information acquisition time. Engine output) is stored in the data table.

  Note that the information acquisition unit 21 may acquire the information acquired from the ship control unit 10 in a state where the information is processed. For example, when the ship information from the ship control unit 10 includes operation information and sea state information acquired at a short time interval, the data becomes large and the subsequent processing load increases. Therefore, the information acquisition part 21 may acquire the average value in a predetermined time interval as ship information. For example, when acquiring the wind speed, the speed of the ship 40, and the output, the information acquisition unit 21 may calculate an average value of the wind speed, speed, and output every 20 minutes and use it for the subsequent calculation. However, the calculation may be performed by the ship control unit 10.

  The information classification unit 22 divides the sea state into a plurality of sea state ranks based on the sea state information, and separates the operation information for each sea state rank. Sea rank is ranked according to the magnitude of the influence on the operation of the ship 40. For example, “Beaufort wind class” or the like can be used as a sea state. As described above, when the wind speed is employed as the sea state rank, the acquired sea state information includes information on the magnitude of the wind speed. Therefore, the information classification unit 22 prepares a marine state rank by performing a plurality of ranks in advance on the magnitude of the wind speed. Then, the information sorting unit 22 sorts the data in the data table of the storage unit 26 into sea state ranks.

  For example, a case where the information sorting unit 22 sorts the driving information in the data table of FIG. 3 will be described. Further, the sea state rank is assumed to have 13 ranks “sea state 0 to 12” in order from the lowest wind speed. The information classification unit 22 refers to the wind speed of data No1 and determines which marine rank the wind speed corresponds to. When the wind speed is large and belongs to “sea state 8”, the information classification unit 22 separates the speed and output of data No. 1 into “sea state 8”. Similarly, the information classification unit 22 refers to the wind speed of data No. 2 and determines which marine rank the wind speed corresponds to. When the wind speed is an intermediate value and belongs to “sea state 4”, the information separation unit 22 separates the speed and output of data No. 2 into “sea state 4”. Similarly, the information sorting unit 22 sorts the operation information in the data table into any sea state rank of “sea state 0 to 12”.

  Examples of the operation information thus sorted are shown in FIGS. 4 and 5. 4 and 5, when one parameter of the operation information is “(ship) speed” and the other parameter is “(main engine) output”, the horizontal axis is the speed, and the vertical axis Is a graph in which the classified driving information is plotted for each sea state rank. FIG. 4 shows a graph of operation information classified into “sea conditions 1 to 4”, and FIG. 5 shows a graph of operation information classified into “sea conditions 5 to 8”. In addition, the curve shown with the continuous line in each graph is a curve of the plan output planned beforehand. The planned output is a relationship between the design speed and the output calculated in consideration of the specifications and performance of the target ship 40.

  The adjustment unit 23 adjusts the display mode so that the driving information sorted by the information sorting unit 22 is displayed so as to be distinguishable for each sea state rank. That is, the adjustment unit 23 visually displays which driving information is classified into which marine rank when the information sorting unit 22 displays the driving information sorted according to the marine rank on the display units 47, 32, and 62. The display information is adjusted so that it can be distinguished.

  The adjustment unit 23 may prepare a graph for each sea state rank, and plot the relationship between the first parameter and the second parameter of the operation information on each graph. Specifically, as shown in FIGS. 4 and 5, the adjustment unit 23 prepares a graph for each sea state rank (sea state 1 to 8), and plots the operation information corresponding to the sea state rank in the graph. You may display on the display part 47,32,62. In the example of FIGS. 4 and 5, the speed is the first parameter and the output is the second parameter. The vertical axis may be speed and the horizontal axis may be output.

  Moreover, the adjustment part 23 may create a 1st approximate line with respect to the graph which plotted the relationship between the 1st parameter of driving information, and a 2nd parameter. The adjustment unit 23 may create a first approximate line for each sea state rank. For example, as shown in FIGS. 4 and 5, a large number of relationships between the first parameter and the second parameter are plotted in the graph at each sea state rank. Therefore, the adjustment unit 23 creates a first approximate line for such a large number of plots. When the adjustment unit 23 creates the first approximate line, any approximate line creation method may be employed, for example, power approximation, polynomial approximation, exponential approximation, linear approximation, logarithmic approximation, moving average, etc. Any method may be adopted. Further, the order when polynomial approximation is adopted is not particularly limited.

For example, FIG. 6 shows an example in which a first approximate line is created for the plots of the sea state rank graphs shown in FIG. 4 and FIG. As shown in FIG. 5D, the number of plots of “sea state 8” is one and an approximate line cannot be created. Therefore, in FIG. 6, the first approximate line corresponding to the sea state 8 is not described. The adjustment unit 23 may cause the display units 47, 32, and 62 to display the first approximate line created for each sea state rank (sea state 1 to 8) as shown in FIG. In order to create the first approximate line in FIG. 6, the following equation (1) is used. In equation (1), “P” indicates the output (of the main engine) and “V” indicates the speed (of the ship). The coefficient (a, b, p) in the formula (1) is applied with a different value for each sea state rank.

P = a + bV ^p (1)

  Here, the accuracy of the first approximate line depends on the number of plots of each sea state rank. Therefore, when the number of plots is significantly smaller than other sea state ranks, the accuracy of the first approximate line for the sea state rank is lowered. For example, as shown in FIG. 6, the first approximate line for “sea state 6, 7” having a small number of plots has an extremely small inclination compared to the other first approximate lines.

  Therefore, the adjustment unit 23 may create the second approximate line for each sea state rank by adjusting the first approximate line based on the relationship with the first approximate line of another sea state rank. That is, when a plurality of first approximate lines are created, an overall tendency is observed to some extent in the shape of the approximate lines. However, when the number of plots of the sea state rank is too small, the first approximate line for some sea state ranks deviates extremely from the tendency. Therefore, the adjustment unit 23 adjusts the first approximate line that is extremely deviated to match the tendency of the first approximate line of another sea state rank.

Specifically, the adjustment unit 23 extracts the coefficient of the approximate expression of the first approximate line created for each sea state rank. Next, the adjusting unit 23 adjusts the coefficient by smoothing the coefficient based on the relationship with the coefficient of other sea state rank. Thereafter, the adjusting unit 23 creates a second approximate line by introducing the adjusted coefficient into the approximate expression. For example, as described above, when the first approximate line as shown in FIG. 6 is created, a coefficient (a, b, p) is extracted for each sea state rank. Any one of the three coefficients extracted for oceanographic 1-7 are plotted in the graph shown in FIG. 8 (a). In this case, the coefficients of the sea scenes 6 and 7 with a small number of plots are greatly deviated from the coefficients of the other sea rank ranks. Therefore, the adjustment unit 23 smoothes the coefficients of the sea conditions 6 and 7 based on the relationship with the coefficients of the sea conditions 1 to 7.

Although the smoothing method is not particularly limited, the adjustment unit 23 smoothes each coefficient by performing fairing on the coefficient of each sea state rank. Although the fairing method is not particularly limited, for example, the adjustment unit 23 may create an approximate line for each coefficient, and may employ a value on the approximate line as a coefficient after adjustment. As a method for creating the approximate line, the method exemplified in the first method for creating the approximate line may be used. For example, the adjustment unit 23 may fair the coefficients using a quadratic approximation as shown in the following formula (2). It should be noted that any coefficient of (a, b, p) to be approximated is entered in “Y” of Equation (2). “X” is the sea state rank (for example, X = 6 for sea state 6).

Y = αX * X + βX + γ (2)

  In the example illustrated in FIG. 8B, the approximate line L1 created by the adjusting unit 23 based on the coefficients of the sea conditions 1 to 7 is illustrated. For the sake of explanation, in FIG. 8B, the portion corresponding to the sea conditions 6 and 7 in the approximate line L1 is enlarged and conceptually shown. Then, the value on the approximate line L1 at the position of “6, 7” on the horizontal axis is used as the coefficient for the sea conditions 6, 7. In FIG. 8 (a), the coefficients of sea conditions 6 and 7 are significantly different from the coefficients of other sea conditions. On the other hand, as shown in FIG. 8B, by adopting the value of the approximate line L1 as a new coefficient for the sea conditions 6 and 7, the coefficient can be adjusted to a value that takes into account the tendency of other sea conditions. it can. Note that the adjustment unit 23 may use a value on the approximate line L1 as a new coefficient not only for the sea conditions 6 and 7, but also for other sea condition rank coefficients. Thereby, the whole coefficient of sea conditions 1-7 can be adjusted to the value which considered the tendency of other sea conditions. After extracting and fairing the coefficient “a” of the sea conditions 1 to 7, the coefficient “b” and the coefficient “p” are similarly faired. In this way, the adjustment unit 23 acquires (a ｀, b ｀, p ｀) as smoothed coefficients for each sea state rank. The adjustment unit 23 substitutes the smoothed (a ｀, b ｀, p ｀) into the above-described equation (1) to create a second approximate line. The second approximate line thus obtained is shown in FIG. The adjustment unit 23 may display the second approximate line after fairing on the display units 47, 32, and 62 as shown in FIG.

  Next, processing contents executed by the server 20 will be described with reference to FIG. FIG. 9 is a flowchart of processing contents executed by the server 20. Moreover, the following processes are processes which the ship information providing program causes the ship information providing apparatus 150 to execute. Such a ship information providing program may be stored in a non-transitory computer-readable storage medium.

  First, the information acquisition unit 21 performs information acquisition step S10 for acquiring ship information including at least operation information related to the operation of the ship 40 and sea state information related to the sea condition during operation of the ship 40 from a plurality of ships 40 via communication. Execute.

  The information classification unit 22 performs an information classification step S20 that divides the sea state into a plurality of sea state ranks based on the sea state information and separates the operation information for each sea state rank. Next, the adjustment part 23 performs the adjustment step (S30-S60) which adjusts a display mode so that the driving information classified by information classification step S20 is displayed so that distinction for every sea state rank.

  Specifically, the adjustment unit 23 creates a first approximate line for each sea state rank with respect to a graph in which the relationship between the first parameter and the second parameter of the driving information is plotted. The creation step S30 is executed. In this case, the adjustment unit 23 uses the plots as shown in FIGS. 4 and 5 to create a first approximate line as shown in FIG. 6 for each sea state rank.

  The adjustment unit 23 executes a coefficient extraction step S40 for extracting the coefficient of the approximate expression of the first approximate line created for each sea state rank. The adjustment unit 23 extracts (a, b, p) obtained by the above-described equation (1) for each sea state rank. Next, the adjustment unit 23 executes a smoothing step S50 that smoothes and adjusts the coefficient based on the relationship with the coefficient of another sea state rank. The adjustment unit 23 smoothes the coefficient (a, b, p) for each sea state rank by performing fairing using the above-described equation (2). The adjusting unit 23 executes the second approximate line creating step S60 for creating the second approximate line by introducing the adjusted coefficient into the approximate expression.

  The operation and effect of the ship information providing apparatus 150, the ship information providing program, the storage medium, the ship information providing method, and the ship information providing system 100 according to the present embodiment will be described.

  In this ship information providing device 150, the information classification unit 22 divides the sea state into a plurality of sea state ranks based on the sea state information, and separates the operation information for each sea state rank. Therefore, the information classification unit 22 considers the sea conditions that affect the operational state of the ship and sets the sea state ranks that are ranked based on the magnitude of the influences of the sea conditions. Each can be separated. Moreover, the adjustment part 23 adjusts a display mode so that the driving information classified by the information classification part is displayed so that it can be distinguished for each sea state rank. Thereby, the user can easily understand to which marine rank the displayed driving information belongs. That is, the user can confirm the operational state of the ship after taking into account the influence of sea conditions. As described above, the value of the ship information provided to the user can be increased.

  In the ship information providing apparatus 150, the adjustment unit 23 creates an approximate line for a graph in which the relationship between the first parameter and the second parameter of the operation information is plotted, and creates an approximate line for each sea state rank. It's okay. This makes it easier for the user to grasp the operational state of the ship for each sea state rank.

  In the ship information providing apparatus 150, the adjustment unit 23 creates a first approximate line for each sea state rank with respect to the graph in which the relationship between the first parameter and the second parameter of the operation information is plotted. The second approximate line may be created for each sea state rank by adjusting the first approximate line based on the relationship between the sea rank and the first approximate line. For example, when the number of plots for a certain marine rank is too small, the accuracy of the information indicated by the first approximate line is reduced (for example, sea states 6 and 7 in FIG. 6). On the other hand, the adjusting unit 23 creates the second approximate line by adjusting the first approximate line based on the relationship with the first approximate line of another sea state rank. The second approximate line is an approximate line that reflects the overall tendency in consideration of approximate lines of other marine ranks. Therefore, the user can confirm more accurate information that is physically consistent.

  In the ship information providing apparatus 150, the adjustment unit 23 extracts the coefficient of the approximate expression of the first approximate line created for each sea state rank, and smoothes and adjusts the coefficient based on the relationship with the coefficient of other sea state ranks. Then, the second approximate line may be created by introducing the adjusted coefficient into the approximate expression. In this case, the user can confirm highly accurate information that is more physically consistent.
