Description

  The present invention relates to a ship performance evaluation system that manages ship operation data and evaluates ship performance based on these operation data.

Conventionally, for example, when operating a main engine of a ship (diesel main engine, etc.), the output performance of various devices constituting the main engine is detected, and the operation is performed so as to be optimized while collating those information with an intended performance diagram. Setting the state is done.
For example, in Patent Document 1, a main engine shaft twist amount, an engine shaft rotation speed, a fuel supply flow rate to the engine, and the like are measured in real time, and based on these measurement results, performance analysis and comparison with expected performance are performed. A technique is disclosed in which the setting of the main engine operation is quickly and appropriately performed by automatically performing.
JP-A-8-285732 (FIG. 1)

By the way, in ship operation management, in addition to what is used for real-time main engine operation during operation as described above, operation data over a long period is accumulated, and the propulsion performance of the ship based on these accumulated operation data. It is necessary to comprehensively evaluate the state of the ship such as ship speed, horsepower, propeller rotational speed, etc.
In the evaluation of such propulsion performance, it is necessary to use long-term operation data. However, since this operation has been performed manually, the burden on the operator is large and the ship's There was a problem that the evaluation could not be performed quantitatively. For example, when one hour of measurement data is saved in one file, 24 files are created in one day. For this reason, the operation data for one month becomes enormous, and the work is extremely complicated, and a large amount of labor is imposed on the worker.

  The present invention was made in order to solve the above-described problems, and while reducing the burden on the operator, a ship performance evaluation system capable of quantitatively performing ship performance evaluation easily and in a short time, and The purpose is to provide a navigation information file creation method and program.

In order to solve the above problems, the present invention employs the following means.
The present invention provides operation data storage means storing a plurality of operation data files in which navigation operation data is recorded at predetermined time intervals, and the plurality of operation data stored in the operation data storage unit. There is provided a ship performance evaluation system including a voyage information file creating means for creating a voyage information file by grouping files for each voyage.

  According to such a configuration, by analyzing each operation data of a plurality of operation data files stored in the operation data storage means, operation data files related to one voyage are grouped into one voyage information file. It is put together. As described above, since a plurality of operation data files stored in the operation data storage means are automatically grouped for each voyage, it is possible to reduce the labor of the operator.

  In the ship performance evaluation system, the operation data includes data recording time and position information, and the voyage information file creation means identifies departure and entry from the port based on the position information in each operation data. The navigation data file may be created by grouping operation data files corresponding to the voyage time until entering the port.

  According to such a configuration, by analyzing each operation data of a plurality of operation data files stored in the operation data storage means, the departure and entry are specified based on the location information where the operation data is recorded. Then, the time at that time is also specified, and the operation data file acquired from the departure time to the arrival time is determined to be an operation data file for one voyage, and is collected into one voyage information file. As described above, since a plurality of operation data files stored in the operation data storage means are automatically grouped for each voyage, it is possible to reduce the labor of the operator.

  In the ship performance evaluation system, the operation data includes a ship speed, an engine speed, and a time, and the voyage information file creation means is based on the ship speed or / and the engine speed of each of the operation data, The departure time and the arrival time of each voyage may be determined, and the voyage information file may be created by grouping operation data files corresponding to the voyage time from the departure time to the arrival time.

  According to such a configuration, by analyzing each operation data of the plurality of operation data files stored in the operation data storage means, the departure time and the arrival time of each voyage can be obtained from the ship speed or / and the engine speed. It is determined that the operation data file acquired from the departure time to the arrival time is an operation data file relating to one voyage, and is compiled into one voyage information file. As described above, since a plurality of operation data files stored in the operation data storage means are automatically grouped for each voyage, it is possible to reduce the labor of the operator.

  The voyage information file creation means, when determining the entry / exit time based on the ship speed, for example, determines that the ship has departed when the ship speed is equal to or higher than a preset ship speed threshold, and its operation data The time when is acquired is determined as the departure time. Further, the voyage information file creation means determines, for example, that the port has entered the port when the boat speed is equal to or lower than a preset port entry boat speed threshold, and determines the time when the operation data is acquired as the port entry time.

The voyage information file creation means determines the departure / departure when determining the entry / exit time based on the engine speed, for example, when the engine speed becomes equal to or higher than a preset departure speed threshold, The time when the operation data is acquired is determined as the departure time. The voyage information file creation means determines that the port has entered when, for example, the engine speed is less than or equal to a preset port speed threshold value, and determines the time when the operation data is acquired as the port entry time.
As described above, since the entry / exit is determined based on the engine speed, even when the position information by GPS cannot be acquired and the ship speed cannot be obtained, the entry / exit time can be determined.

  Also, by determining the port entry / exit time using both the ship speed and engine speed, the engine speed is taken into account even when the reliability of the ship speed being measured is reduced due to the effect of dynamic pressure. Thus, it is possible to accurately detect entry / exit. Thereby, it becomes possible to improve the determination accuracy of the port entry / exit time.

In the ship performance evaluation system, the voyage information file creation means creates a voyage information file for this voyage when the voyage time from the departure time to the entry time is less than or equal to a preset voyage threshold. It is good not to do.
Alternatively, in the ship performance evaluation system, the voyage information file creation means may determine that the number of the operation data files constituting one voyage is less than or equal to a preset file number threshold. It is good also as not creating the voyage information file in a voyage.

  For example, when a ship enters the port, there may be a case where “off the sea” is instructed to temporarily go offshore and enter the port again in relation to another ship. When such “Oki Dashi” is performed, there is a possibility that it will be determined as one voyage because the operation of entering port-departing-entering port is taken once. Even in such a case, when the voyage time is less than or equal to the preset voyage threshold, or when the number of operation data files constituting one voyage is less than or equal to the preset file number threshold Therefore, since the navigation information file is not created in this voyage, it is possible to avoid a false detection in which a series of actions due to “offshore” is counted as one voyage.

  In the ship performance evaluation system, based on one or more of the voyage information files, drawing means for creating image data for visualizing ship information relating to voyage, and an image created by the drawing means are output. It is good also as providing an output means.

  Since ship information related to the voyage is visualized and output based on the voyage information file, the operator can easily grasp the state of the voyage and the state of the ship by looking at the output result. . The output means is, for example, a display means such as a liquid crystal display or a CRT monitor, or a printing means such as a printer. Furthermore, by visualizing the contents of the voyage information file, the operator can easily confirm whether or not there is any omission or abnormality in the operation data of the voyage information file.

  The ship performance evaluation system may further include file editing means that allows an operator to modify, add, or delete the voyage information file created by the voyage information file creating means.

  Since it has file editing means that enables the operator to modify, add, and delete the voyage information file created by the voyage information file creation means, the operator modifies the contents of the automatically created voyage information file, It becomes possible to add and delete. For example, when the GPS mounted on the ship does not function normally temporarily, information such as the ship speed, latitude, and longitude is not temporarily acquired. Even if the operation data file has operation data that has not been completely created, the operator himself / herself considers the operation data before and after the operation data, the data of other items in the operation data, etc. By adding it to the voyage information file, it becomes possible to use more operation data effectively. As described above, since the file editing means that enables editing by the operator is provided, the operation data can be used more effectively, and the reliability of ship performance analysis described later can be improved.

  The ship performance evaluation system includes basic information storage means storing basic information unique to a ship, operation data of the voyage information file, and basic information unique to the ship stored in the basic information storage means. And performance evaluation means for evaluating the performance of the ship in each voyage.

  Since the performance evaluation means for evaluating the performance of the ship in each voyage is provided, the performance evaluation of the ship can be automatically performed. As a result, the burden on the operator can be reduced.

  The present invention is a navigation information file creation method for creating a navigation information file by grouping a plurality of operation data files in which navigation operation data including data recording time and position information are recorded at predetermined time intervals for each navigation. A voyage information file creation method for creating a voyage information file by specifying departure and entry based on position information in each of the operation data, and grouping operation data files corresponding to voyage times from the departure to entry I will provide a.

  According to the present invention, it is possible to reduce the burden on the operator by automatically managing and analyzing the operation data. Moreover, according to this invention, there exists an effect that the performance evaluation of a ship can be performed quantitatively easily in a short time.

An embodiment of a ship performance evaluation system according to the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing a schematic configuration of a ship performance evaluation system according to the present embodiment.
The ship performance evaluation system 1 according to the present embodiment is an operation data storage in which a plurality of operation data files including a plurality of operation data acquired by various instruments mounted on the ship are stored during the navigation of the ship. A unit (operation data storage means) 2, a basic information storage unit (basic information storage means) 3 in which basic information of the ship is stored, a calculation result storage unit 4 for storing calculation results by the processing unit 6 described later, An input unit 5 in which an input operation is performed by an operator, a processing unit 6 that performs various calculations, and a display unit (output unit) 7 that outputs a calculation result or the like by the processing unit 6 are provided.

  The operation data is data acquired at regular time intervals during the voyage of the ship. For example, the speed of the ground ship, engine speed, time, latitude, longitude, course, main engine speed, fuel rack position, fuel consumption , Fuel oil temperature, supply air temperature, cooling water temperature, main engine speed, engine room temperature, shaft horsepower, shaft speed, bow draft, stern draft, relative wind speed, relative wind direction, water speed, snake angle, hull motion, Examples include acceleration and wave height.

  The said operation data are put together into one operation data file for every arbitrary time (for example, 1 hour) for the data measured for every arbitrary measurement time interval (for example, 20 seconds). For example, in the case of a 24-hour voyage, 24 operation data files are created. Thus, since a plurality of operation data are created in one voyage, an enormous number of operation data files are accumulated in the operation data storage unit 4 throughout the year.

  The operation data may be transmitted from the ship in real time during the voyage, or the operation data is stored in a recording device mounted on the ship, and the stored operation data is stored for a certain period. It is also possible to transfer them in batches. Thus, in the present invention, the method for storing the operation data in the operation data storage unit is not particularly limited.

  The basic information storage unit 3 is operated by the performance evaluation system such as the latitude and longitude of each port where the ship enters and exits, map information, ship-specific basic performance information possessed by the shipyard, and functional expressions for calculating various characteristics. Various information necessary for data management and performance evaluation is stored.

The input unit 5 is a man-machine interface such as a keyboard and a mouse.
The display unit 7 is, for example, a CRT monitor or a liquid crystal display.

As shown in FIG. 2, the processing unit 6 groups the enormous number of operation data accumulated in the operation data storage unit 2 described above for each voyage, and collects the operation data related to one voyage as one voyage information file. A voyage information file creation unit (voyage information file creation means) 11 is provided.
Further, as shown in FIG. 2, the processing unit 6 creates image data for visualizing ship information related to voyage based on one or more voyage information files created by the voyage information file creating unit 11. A drawing section (drawing means) 12, a file editing section (file editing means) 13 that enables the operator to modify, add, and delete the voyage information file created by the voyage information file creation section 11, and a voyage information file; Based on the basic information stored in the basic information storage unit 3, a performance evaluation unit (performance evaluation unit) 14 that performs ship performance evaluation in each voyage or a plurality of voyages is provided.

  The processing unit 6 has a configuration in which, for example, software necessary for realizing the functions of the respective units is included in hardware mainly including a computer. Specifically, the processing unit 6 includes a CPU (Central Processing Unit) (not shown), a main storage device such as a RAM, and a computer-readable recording medium on which various data are recorded.

A series of processing procedures for realizing the functions of the respective units described above are recorded in a computer-readable recording medium in the form of a program, and the CPU reads the program into a RAM or the like to perform information processing / arithmetic processing. By executing the functions, the navigation information file creation unit 11, the drawing unit 12, the file editing unit 13, the performance evaluation unit 14, and the like are realized.
Here, the computer-readable recording medium means a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, or the like. Alternatively, the computer program may be distributed to the computer via a communication line, and the computer that has received the distribution may execute the program.

  The voyage information file creation unit 11 creates a voyage information file by grouping the operation data files for each voyage based on, for example, port information of each operation data stored in the operation data storage unit 2. When the voyage information file creation unit 11 creates a voyage information file in which operation data files for each voyage are collected, the voyage information file creation unit 11 stores the voyage information file in the calculation result storage unit 4. Thereby, the operation result storage unit 4 stores a plurality of voyage information files in which operation data files are grouped for each voyage.

  The drawing unit 12 has a function of creating various characteristic diagrams for confirming the state of the voyage based on the voyage information file. For example, the drawing unit 12 has a characteristic diagram creation function that shows the state of the ship speed, course, engine speed, fuel consumption, etc. in time series, correlation between engine speed and ground speed, pod torque and pod speed. And a correlation map creation function showing the correlation between the shaft horsepower and the shaft rotation speed, a wake map creation function showing the route on one map on a map, and the like.

  For example, based on a plurality of voyage information files, the file correcting unit 13 displays an operation calendar that shows the operation state of a ship in a predetermined period such as one month in association with port entry / exit information and port entry / exit times in time series. By displaying on the display unit 7, the navigation information file can be corrected, added, or deleted by the operator on the operation calendar. The editing work by the operator is reflected in the voyage information file, and the updated voyage information file is stored in the calculation result storage unit 4.

  The performance evaluation unit 14 performs performance evaluation on the ship using the voyage information file stored in the calculation result storage unit 4 and the ship-specific basic information stored in the basic information storage unit 3. For example, the performance evaluation unit 14 analyzes speed characteristics, fuel characteristics, horsepower characteristics, and the like, and outputs the analysis results to the display unit 7.

Next, the operation of each part of the ship performance evaluation system 1 having the above configuration will be specifically described.
First, when the ship performance evaluation system 1 is activated, an initial screen is displayed on the display unit 7.
For example, as shown in FIG. 3, the initial screen includes a file creation instruction button 21 for instructing automatic creation of a voyage information file, a file edit instruction button 22 for instructing editing of a voyage information file, and ship performance based on the voyage information file. A performance evaluation instruction button 23 for instructing evaluation and first to third drawing instruction buttons 24 to 26 for instructing drawing are provided.

  In this initial screen, when the operator operates the input unit 5 (see FIG. 1) and the file creation instruction button 21 is selected, as shown in FIG. 4, operation data from which a navigation information file is created is generated. A file range specification screen for specifying the file range is displayed. In this file range specification screen, when an operator operates the input unit 5 and an operation data file in a predetermined range is specified from among the enormous operation data files stored in the operation data storage unit 2, The navigation information file creating unit 11 automatically creates a voyage information file using the operation data file corresponding to the specified range.

FIG. 5 is a diagram showing extracted components related to the creation of the navigation information file.
First, when the range of the operation data file is designated by the operator, the navigation information file creation unit 11 extracts the operation data file from the operation data storage unit 2. Subsequently, by analyzing all the operation data of the extracted operation data file, the operation data recorded at the time of departure from the port and the operation data recorded at the time of arrival at the port are specified.
Specifically, the voyage information file creation unit 11 arranges the extracted operation data files in time series, then analyzes the longitude / latitude information in all the operation data, and the longitude / latitude information and the basic information storage unit 3 The operation data having the position information matching the latitude and longitude of the port is extracted by checking the longitude and latitude of the port registered as the initial setting file.

Subsequently, by analyzing the speed and engine speed in the operation data, it is determined whether the port is entering or leaving the port. For example, regarding departure from a port, operation data in which the speed is equal to or lower than a preset departure speed threshold and the engine speed is equal to or lower than the departure speed is extracted. Is judged to be leaving the port.
In addition, with regard to entry into the port, operation data in which the speed is less than or equal to a preset entry speed threshold and the engine speed is less than or equal to the entry speed is extracted. If the number seems to drop gradually, it is judged that the port has entered.

  In addition, the specific method of the operation data at the time of the above-mentioned entrance / exit is not limited to the said method. For example, when an initial setting file includes a voyage schedule in which the port entry date / time and port location information, and the port departure date / time and port location information are registered, the operation data is close to the port entry date / time. In addition, by extracting operation data whose position information matches the position information of the port, the operation data at the time of entering the port is specified, the operation data is close to the departure date and time, and the position information is the position of the port. By extracting operation data that matches the information, the operation data at the time of departure is identified.

  In this way, when the operation data relating to the time of departure and entry of the port is specified, the departure time and the entry time are specified from the recording time of these operation data, and the operation data corresponding to the voyage period from the specified departure time to the entry time is determined. Is identified as operation data relating to this voyage. Then, the navigation data file is created by grouping the operation data corresponding to the navigation period, identification information is given to the created navigation information file, and the result is stored in the calculation result storage unit 4.

In this case, the voyage information file creation unit 11 may not create the voyage information file for this voyage when the voyage time is less than or equal to a preset voyage threshold.
For example, when a ship enters the port, there may be a case where “off the sea” is instructed to temporarily go offshore and enter the port again in relation to another ship. When such “Oki Dashi” is performed, there is a possibility that it will be determined as one voyage because the operation of entering port-departing-entering port is taken once. Even in such a case, if the voyage time is less than or equal to the preset voyage threshold, a series of actions by “Oki Dashi” is not performed for one voyage by not creating a voyage information file for this voyage. Can be avoided.

  In addition, instead of the method based on the voyage period as described above, when the number of operation data files constituting one voyage is equal to or less than a preset file number threshold, the voyage information in this voyage It is also possible not to create a file. In this way, it is possible to avoid erroneous file creation due to the above-mentioned “Oki Dashi” also depending on the number of operation data files constituting one voyage information file.

  FIG. 6 is a diagram showing an example of a voyage information file created by the voyage information file creation unit 11. As shown in FIG. 6, in the voyage information file N, it can be seen that 15 operation data files are grouped to create one voyage information file.

Further, when the voyage information file creation unit 11 creates the voyage information file, it creates image data for visualizing the voyage information file and outputs the image data to the display unit 7. Thereby, information such as grouping of the voyage information file is displayed on the display unit 7.
FIG. 7 is a diagram showing an example of a screen on which the contents of the voyage information file are displayed. FIG. 7 shows the contents of a voyage information file for 22 voyages carried out during the period from January 9, 2005 to January 30, 2005. On this screen, for each voyage information file, the departure name, departure time, arrival name, arrival time, voyage period, number of operation data files constituting the voyage information file, folder name of the voyage information file, and The names of the operation data files that make up the cruise information file are displayed.

  In this way, the contents of the voyage information file are visualized by displaying the contents of the voyage information file on the display unit 7, so that the operator can confirm how this screen is displayed by checking this screen. It is possible to easily confirm whether a voyage has been made.

  Next, a case where the first drawing instruction button 24 for instructing drawing is selected by operating the input unit 5 (see FIG. 1) on the initial screen shown in FIG. 3 will be described. When the first drawing instruction button 24 is selected, a file selection screen for selecting a navigation information file to be displayed is displayed as shown in FIG. In this file selection screen, when a predetermined navigation information file is specified from among a plurality of navigation information files stored in the calculation result storage unit 4 by the operator operating the input unit 5, the specified navigation information is displayed. Drawing using the information file is executed by the drawing unit 12.

FIG. 9 is a diagram showing extracted components related to drawing.
First, when the navigation information file is designated by the operator, the drawing unit 12 extracts the designated navigation information file from the calculation result storage unit 4. Subsequently, a navigation chart, a characteristic chart, and a correlation chart are created by analyzing all the operation data files that constitute the extracted navigation information file.

  For example, as shown in FIG. 10, the drawing unit 12 creates a time series diagram showing how the speed, course, engine room temperature, turbocharger rotational speed, etc. have changed during the voyage. The figure is displayed on the display unit 7. In FIG. 10, a speed characteristic diagram, a course characteristic diagram, an engine room temperature, and a time series diagram of the turbocharger rotational speed are shown in order from the top. In each characteristic diagram, the horizontal axis indicates time. By browsing this time-series diagram, the operator can easily grasp how the speed, course, engine room temperature, turbocharger rotation speed, and the like are changing.

  Further, as shown in FIG. 11, the drawing unit 12 creates a correlation diagram between the speed and the engine room temperature in the voyage, a correlation diagram between the engine room temperature and the sea water temperature, and the like, and displays the created correlation diagram on the display unit 7. To display. Thereby, the operator can easily grasp the correlation between the parameters in the voyage.

  Further, as shown in FIG. 12, the drawing unit 12 creates a wake map showing the route in the voyage on a map, and displays the created wake map on the display unit 7. This wake map is created based on position information consisting of longitude and latitude of operation data. Thus, since the wake map is displayed on the display unit 7, the operator can easily grasp the actual route in the voyage.

  Next, a case will be described in which the file editing instruction button 22 for instructing editing of the navigation information file is selected by operating the input unit 5 (see FIG. 1) on the initial screen shown in FIG. . When the file editing instruction button 22 is selected, a file selection screen for selecting a voyage information file for file editing is displayed as shown in FIG. In this file selection screen, when the input unit 5 is operated by the operator, a predetermined voyage information file is designated from among a plurality of voyage information files stored in the calculation result storage unit 4. The editing function of the navigation information file is executed by the file editing unit 13.

FIG. 13 is a diagram showing extracted components related to file editing.
First, when a cruise information file is designated by the operator, the file editing unit 13 extracts the designated cruise information file from the calculation result storage unit 4. For example, when a plurality of voyage information files are specified, the specified voyage information files are extracted. Subsequently, the port entry / exit time and the port entry / exit name of the extracted voyage information file are extracted, and an operation calendar is created based on these information.

  For example, the file editing unit 13 displays an operation calendar as shown in FIG. In FIG. 14, the horizontal axis indicates the date and time, and the vertical axis indicates the position of entry / exit. Here, the open squares indicate departures, and the black squares indicate arrivals. In FIG. 14, it turns out that the said ship is going back and forth between A port, B port, and C port. For example, it can be seen that in the early morning of January 20, the port C was departed and entered the port A that night. Furthermore, it can be seen that a few hours later, port A was departed and sailed toward port B. In this way, since the operation calendar showing the state of the voyage in time series is displayed on the monitor, the operator can easily check for missing or abnormal voyage information files.

  For example, in the operation calendar shown in FIG. 14, it can be seen that there is no corresponding voyage information file between the night of January 18 and the early morning of January 20. At this time, on the night of January 18th, we entered port B, and in the early morning of January 20th we left port C, so between January 18th and January 20th At least, it is understood that there is no information about the voyage from port B to port C. When the operator finds such a missing navigation information file, the operator operates the input unit 5 to designate the missing portion as an editing range. Thereby, as shown in FIG. 15, the edit range of the said operation | movement calendar will be designated.

When the editing range is designated by the operator in this way, the file editing unit 13 searches the operation data storage unit 2 for an operation data file corresponding to the editing range. For example, it is searched whether or not there is an operation data file having operation data recorded at the date and time designated as the editing range. As a result, if there is an operation data file having operation data recorded at the date and time designated as the editing range, all the operation data files are extracted from the operation data storage unit 2. FIG. 16 is a diagram showing a part of the contents of the operation data extracted from the operation data storage unit 2 by the file editing unit 13. In FIG. 16, the operation data recorded on the night of January 19 is shown as an example.
The file editing unit 13 creates a characteristic diagram and a wake map based on the extracted operation data, and displays the created characteristic diagram and wake map on the display unit 7. As a result, the characteristic diagram shown in FIG. 17 and the wake map shown in FIG. 18 are displayed on the display unit 7.

  The operator browses these characteristic maps and track maps and designates data to be added to the editing range designated earlier. For example, the operator designates a section to be added to the editing range in the characteristic diagram shown in FIG. As described above, when the operator gives an additional instruction, the file editing unit 13 groups the operation data files belonging to the designated section to create one voyage information file, and adds identification information to the voyage information file. The result is stored in the calculation result storage unit 4. Further, when the navigation information file is reorganized by the file editing unit 13, the operation calendar shown in FIG. 15 is updated based on the navigation information file after the organization.

  Thus, since it has an editing function by the operator, it is excluded from the creation of the navigation information file by the navigation information file creation unit 11 due to, for example, a defect in the data referred to when creating the navigation information file. If there is any operation data, the operation data can be added to the navigation information file at the discretion of the operator. Thereby, subsequent performance evaluation can be performed using more operation data.

  Next, on the initial screen shown in FIG. 3, the operator operates the input unit 5 (see FIG. 1) to select the performance evaluation instruction button 23 for instructing ship performance evaluation based on the voyage information file. The case will be described. When the performance evaluation instruction button 23 is selected, a file selection screen for selecting a voyage information file for performance evaluation is displayed as shown in FIG. In this file selection screen, when the input unit 5 is operated by the operator, a predetermined voyage information file is designated from among a plurality of voyage information files stored in the calculation result storage unit 4. The performance evaluation unit 14 executes the performance evaluation of the ship based on the voyage information file.

FIG. 19 is a diagram showing components extracted for performance evaluation.
First, when the navigation information file is designated by the operator, the performance evaluation unit 14 extracts the designated navigation information file from the calculation result storage unit 4. For example, when a plurality of voyage information files are specified, the specified voyage information files are extracted. Subsequently, the performance evaluation unit 14 reads data related to performance evaluation from the initial setting file of the basic information storage unit 3. And the performance evaluation of the said ship is performed using the data regarding these performance evaluations, and the operation data of each voyage information file.

  For example, the performance evaluation unit 14 determines evaluation values such as total output, fuel consumption, fuel rate, horsepower, draft, horsepower, flat water horsepower, draft trim drainage, draft drainage, T / C turbocharger horsepower, and the like in each voyage. calculate. The function formula, initial value, correction value, and various coefficients for calculating these various evaluation values are set in the initial setting file of the basic information storage unit 3.

As described above, the first time-series characteristic diagram showing the various measurement elements constituting the operation data in the designated navigation information file in time series is displayed on the monitor. Although FIG. 22 shows a single measurement element, a plurality of measurement elements can be displayed in an overlapping manner.

  Further, in the initial screen shown in FIG. 3, when the operator operates the input unit 5 (see FIG. 1) and the third drawing instruction button 26 for instructing drawing is selected, FIG. As shown, a file selection screen for selecting a navigation information file to be displayed is displayed. When a predetermined navigation information file is designated from among a plurality of navigation information files stored in the calculation result storage unit 4 by the operator operating the input unit 5 on this file selection screen, it is shown in FIG. As described above, the second time-series characteristic diagram showing the measurement elements (for example, ship speed) of the operation data in the designated navigation information file in time series is displayed on the monitor. In FIG. 23, speed and the like are shown as measurement elements.

  As described above, according to the ship performance evaluation system according to the present embodiment, by analyzing each operation data of a plurality of operation data files stored in the operation data storage unit 2, it is related to one voyage. Since the navigation information file creation unit 11 that automatically creates a navigation information file by grouping operation data files is provided, it is possible to reduce the labor of the operator.

  The voyage information file creation unit 11 does not create a voyage information file for this voyage when the voyage time from the departure time to the entry time is less than or equal to a preset voyage threshold. It is possible to avoid the creation of a navigation information file for “Oki-dashi”. Thereby, it is possible to improve the creation accuracy of the navigation information file.

  In addition, a drawing unit 12 that creates image data for visualizing ship information related to a voyage based on one or a plurality of navigation information files, and a display unit 7 that displays an image created by the drawing unit 12 are provided. Therefore, it is possible to visualize ship information related to navigation based on the navigation information file. As a result, the operator can easily grasp the state of the voyage and the state of the ship. In addition, the operator can easily confirm whether or not the navigation information file is missing or abnormal.

  In addition, since the voyage information file created by the voyage information file creation unit 11 is provided with a file editing unit 13 that can be modified, added, and deleted by the operator, the operator can edit the automatically created voyage information file. The contents can be modified, added, or deleted. For example, when the GPS mounted on the ship does not function normally temporarily, information such as the ship speed, latitude, and longitude is not temporarily acquired. Even if the operation data file has operation data that has not been completely created, the operator himself / herself considers the operation data before and after the operation data, the data of other items in the operation data, etc. By adding it to the voyage information file, it becomes possible to realize performance evaluation based on more operation data.

Further, using the basic information storage unit 3 in which basic information unique to the ship is stored and the operation data in the navigation information file and the basic information specific to the ship stored in the basic information storage unit 3, the ship in each voyage Since the performance evaluation unit 14 for performing the performance evaluation is provided, the performance of the ship can be automatically obtained. This makes it possible to evaluate the performance of the ship without bothering the operator.
In addition, since the operator can designate a voyage information file to be subjected to performance evaluation, it is possible to perform ship performance evaluation in a desired range.

As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the specific structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.
