The manager terminal 60 may be a terminal installed in a building on land 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 have the same configuration as 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.

The server 20 includes a processor, a memory, a storage, a communication interface, and a user interface, similarly to the ship control unit 10 described above. The processor controls the memory, storage, communication interface, and user interface, and realizes the functions of the server 20, which will be 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 sorting unit 22, an adjusting 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 including an information acquisition unit 21, an information sorting unit 22, an adjusting unit 23, and a transmitting / receiving unit 24.

The information acquisition unit 21 acquires ship information including at least operation information and sea condition 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 vessels 40 via communication. The information acquisition unit 21 can acquire various information acquired by the information acquisition unit 11 of the ship control unit 10. When the information acquisition unit 21 acquires ship information from each ship 40, the information acquisition unit 21 transmits the information to the storage unit 26 and stores the information. The storage unit 26 stores the operation information and the sea condition information in a linked state for each information acquisition time. For example, as shown in FIG. 3, the storage unit 26 has the information acquisition time when the information is acquired, and the "wind speed", "(ship) speed", and "(main)" associated with the information acquisition time. The "output" of the engine is stored in the data table.

The information acquisition unit 21 may acquire the information acquired from the ship control unit 10 in a state of being calculated. For example, when the ship information from the ship control unit 10 includes the operation information and the sea condition information acquired at short time intervals, the data is large and the subsequent arithmetic processing load is large. Therefore, the information acquisition unit 21 may acquire the average value at a predetermined time interval as ship information. For example, when the information acquisition unit 21 acquires the wind speed, the speed and the output of the ship 40, the information acquisition unit 21 may calculate the average value of the wind speed, the speed and the output every 20 minutes and use it for the later calculation. However, the calculation may be performed by the ship control unit 10.

The information sorting unit 22 divides the sea elephant into a plurality of sea elephant ranks based on the sea elephant information, and separates the driving information by the sea elephant rank. The sea elephant 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 image. When the wind speed is adopted as the sea elephant rank in this way, the acquired sea elephant information includes information on the magnitude of the wind speed. Therefore, the information sorting unit 22 prepares the sea elephant rank by ranking the wind speed in a plurality of stages in advance. Then, the information sorting unit 22 sorts the data in the data table of the storage unit 26 into sea elephant ranks.

For example, a case where the information sorting unit 22 sorts the operation information in the data table of FIG. 3 will be described. In addition, the sea elephant rank shall have 13 ranks of "sea elephant 0 to 12" in order from the one with the lowest wind speed. The information sorting unit 22 refers to the wind speed of the data No. 1 and determines which sea condition rank the wind speed corresponds to. When the wind speed is high and belongs to "sea elephant 8", the information sorting unit 22 separates the speed and output of the data No. 1 into "sea elephant 8". Similarly, the information sorting unit 22 refers to the wind speed of the data No. 2 and determines which sea condition rank the wind speed corresponds to. When the wind speed is an intermediate value and belongs to "sea elephant 4", the information sorting unit 22 separates the velocity and output of the data No. 2 into "sea elephant 4". Similarly, the information sorting unit 22 sorts the operation information in the data table into any of the sea elephant ranks of "sea elephants 0 to 12".

Examples of the operation information separated in this way are shown in FIGS. 4 and 5. In FIGS. 4 and 5, when one parameter of the operation information is "speed (of ship)" and the other parameter is "output (of main engine)", the horizontal axis is speed and the vertical axis is vertical axis. Is a graph in which the sorted operation information is plotted for each sea elephant rank with the output of. FIG. 4 shows a graph of driving information sorted into “sea elephants 1 to 4”, and FIG. 5 shows a graph of driving information sorted into “sea elephants 5 to 8”. The curve shown by the solid line in each graph is a curve of the planned output planned in advance. The planned output is the relationship between the design speed and the output, which is calculated in consideration of the specifications and performance of the target ship 40.

The adjusting unit 23 adjusts the display mode so that the operation information sorted by the information sorting unit 22 is displayed in a distinguishable manner for each sea elephant rank. That is, when the information sorting unit 22 displays the driving information sorted by the sea elephant rank on the display units 47, 32, 62, the adjusting unit 23 visually indicates which driving information is sorted into which sea elephant rank. Adjust the display information so that it can be distinguished from each other.

The adjusting unit 23 may prepare a graph for each sea elephant 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 adjusting unit 23 individually prepares a graph for each sea elephant rank (sea elephant 1 to 8), and plots the operation information corresponding to the sea elephant rank in the graph. The displayed items may be displayed on the display units 47, 32, 62. In the examples of FIGS. 4 and 5, velocity is the first parameter and output is the second parameter. The vertical axis may be speed and the horizontal axis may be output.

Further, the adjusting unit 23 may create a first approximate line for a graph plotting the relationship between the first parameter and the second parameter of the operation information. Further, the adjusting unit 23 may create a first approximate line for each sea elephant rank. For example, as shown in FIGS. 4 and 5, many relationships between the first parameter and the second parameter are plotted in the graph for each sea condition rank. Therefore, the adjustment unit 23 creates a first approximation line for such a large number of plots. When the adjusting unit 23 creates the first approximation line, any approximation line creation method may be adopted, for example, a power approximation approximation, a polynomial approximation, an exponential approximation, a linear approximation, a logarithmic approximation, a moving average, or the like. Any method may be adopted. Further, the degree when the polynomial approximation is adopted is not particularly limited.

For example, FIG. 6 shows an example in which a first approximation line is created for the plots of the graphs of each sea elephant rank shown in FIGS. 4 and 5, and the graphs are combined into one graph. As shown in FIG. 5D, the number of plots of "sea elephant 8" is one, and an approximate line cannot be created. Therefore, in FIG. 6, the first approximation line corresponding to the sea elephant 8 is not shown. The adjusting unit 23 may display the first approximate line created for each sea elephant rank (sea elephant 1 to 8) on the display units 47, 32, 62 as shown in FIG. The following equation (1) is used to create the first approximation line in FIG. In equation (1), "P" indicates the output (of the main engine) and "V" indicates the speed (of the ship). Different values are applied to the coefficients (a, b, p) in the equation (1) for each sea elephant rank.

P = a + bV ^p ... (1)

Here, the accuracy of the first approximation line depends on the number of plots of each sea elephant rank. Therefore, when the number of plots is significantly smaller than that of other sea elephant ranks, the accuracy of the first approximation line for the sea elephant rank becomes low. For example, as shown in FIG. 6, the first approximation line for "sea elephants 6 and 7" having a small number of plots has an extremely small slope as compared with the other first approximation lines.

Therefore, the adjusting unit 23 may create a second approximate line for each sea elephant rank by adjusting the first approximate line based on the relationship with the first approximate line of another sea elephant rank. That is, when a plurality of first approximation lines are created, there is a certain degree of overall tendency in the shape of the approximation lines. However, if the number of plots of sea elephant rank is too small, the first approximation line for some sea elephant ranks deviates significantly from this tendency. Therefore, the adjusting unit 23 adjusts the first approximation line that is extremely deviated to match the tendency of the first approximation line of another sea elephant rank.

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

The method of smoothing is not particularly limited, but the adjusting unit 23 smoothes each coefficient by performing fairing on the coefficient of each sea condition rank. The fairing method is not particularly limited, but for example, the adjusting unit 23 may create an approximate line for each coefficient and adopt the value on the approximate line as the adjusted coefficient. As the method for creating the approximate line, the method exemplified in the above-mentioned method for creating the approximate line may be used. For example, the adjusting unit 23 may fair the coefficients using a quadratic approximation formula as shown in the following formula (2). In addition, any coefficient of (a, b, p) to be approximated is entered in "Y" of the formula (2). The sea elephant rank is entered in "X" (for example, in the case of sea elephant 6, X = 6).

Y = αX * X + βX + γ… (2)

In the example shown in FIG. 8B, the approximation line L1 created by the adjusting unit 23 based on the coefficients of the sea objects 1 to 7 is shown. For the sake of explanation, in FIG. 8B, the portion of the approximate line L1 corresponding to the sea conditions 6 and 7 is enlarged and conceptually shown. Then, as the coefficient for the sea conditions 6 and 7, the value on the approximate line L1 at the position of "6, 7" on the horizontal axis is used. In FIG. 8A, the coefficients of the sea elephants 6 and 7 deviate greatly from the coefficients of the other sea elephants. On the other hand, as shown in FIG. 8B, by adopting the value of the approximation line L1 as a new coefficient of the sea elephants 6 and 7, the coefficient can be adjusted to a value considering the tendency of other sea elephants. can. The adjusting unit 23 may use the value on the approximation line L1 as a new coefficient not only for the sea elephants 6 and 7 but also for the coefficients of other sea elephants rank. As a result, the entire coefficient of the sea elephants 1 to 7 can be adjusted to a value in consideration of the tendency of other sea elephants. After extracting and fairing the coefficients "a" of the sea objects 1 to 7, the fairing is performed in the same manner for the coefficients "b" and the coefficients "p". In this way, the adjusting unit 23 acquires (a ｀, b ｀, p ｀) as a smoothed coefficient for each sea elephant rank. The adjusting unit 23 substitutes the smoothed (a ｀, b ｀, p ｀) into the above-mentioned mathematical expression (1) to create a second approximation line. The second approximate line thus obtained is shown in FIG. The adjusting unit 23 may display the second approximate line after fairing on the display units 47, 32, 62 as shown in FIG. 7.

Next, the processing contents executed by the server 20 will be described with reference to FIG. FIG. 9 is a flowchart of the processing content executed by the server 20. Further, the following processing is a processing to be executed by the ship information providing device 150 by the ship information providing program. Such a ship information providing program may be stored in a non-temporary computer-readable storage medium.

First, the information acquisition unit 21 performs an information acquisition step S10 for acquiring at least ship information including driving information regarding the operation of the ship 40 and sea image information regarding the sea image during operation of the ship 40 from a plurality of ships 40 via communication. Run.

The information sorting unit 22 executes the information sorting step S20 in which the sea elephant is divided into a plurality of sea elephant ranks based on the sea elephant information and the operation information is separated for each sea elephant rank. Next, the adjusting unit 23 executes an adjusting step (S30 to S60) for adjusting the display mode so that the operation information sorted in the information sorting step S20 can be displayed distinguishably for each sea elephant rank.

Specifically, the adjusting unit 23 creates a first approximate line for each sea elephant rank with respect to a graph plotting the relationship between the first parameter and the second parameter of the operation information. The creation step S30 is executed. In this case, the adjusting unit 23 creates a first approximate line as shown in FIG. 6 for each sea elephant rank by using the plots shown in FIGS. 4 and 5.

The adjusting unit 23 executes the coefficient extraction step S40 for extracting the coefficient of the approximate expression of the first approximate line created for each sea elephant rank. The adjusting unit 23 extracts (a, b, p) obtained by the above-mentioned mathematical formula (1) for each sea elephant rank. Next, the adjusting unit 23 executes a smoothing step S50 for smoothing and adjusting the coefficients based on the relationship with the coefficients of other sea elephant ranks.
