[0048] 6, 7, and 9 are diagrams showing control flows of a display control device in some embodiments of the present disclosure. FIG. 8 is a diagram showing an example of a data configuration in some embodiments of the present disclosure. FIG. 6 shows an overall flow of the display control device 14. FIG. 7 shows details of STEP 1 in FIG. 6, and FIG. 9 shows details of STEP 2 in FIG. 6. In this embodiment, when providing information about screen display information to be displayed on the display device 40, a two-stage evaluation is performed in STEP 1 in FIG. 7 and STEP 2 in FIG. 9.

[0049] 6, an alarm occurs. When an alarm occurs, alarm information is input to the display control device 14, and the process proceeds to STEP 1 of step S102. In STEP 1, the priority determination unit 142 performs a determination.

[0050] 7 shows details of STEP 1 of step S102. When an alarm occurs in step S101, alarm information is input to the display control device 14, and the acquisition unit 141 acquires the alarm information (S201).

[0051] Next, in step S202, the priority determination unit 142 determines the importance of the generated warning based on the warning information acquired by the acquisition unit 141. In the display control device 14, the importance of the warning information, one or more pieces of warning screen information linked to the warning information, and the priority of displaying the warning screen information are registered in the database DB1 in advance, and the priority determination unit 142 can acquire the importance of the warning information acquired by the acquisition unit 141. The importance of the warning information is assumed to be divided into three levels, for example, high, medium, and low. If it is determined that the importance of the warning information is high (YES in S202), for example, if the importance is high, the process proceeds to step S203. On the other hand, if it is determined that the importance of the warning information is not high (NO in S202), for example, if the importance is medium or low, the process returns to step S101.

[0052] Fig. 8 shows an example of the data configuration of the database DB1 of the display control device 14. As shown in Fig. 8, the database DB1 registers, as information related to alarm information, an ID, an alarm name, an importance level of the alarm, a related screen, and a display priority in association with each other.

[0053] When it is determined that the importance of the alarm information is high, for example when the importance is high, a list of screens related to the generated alarm is acquired (S203 in FIG. 7). The priority determination unit 142 acquires, from the database DB1, one or more pieces of alarm screen information linked to the alarm information acquired by the acquisition unit 141. The one or more pieces of alarm screen information linked to the alarm information are acquired as a list together with the display priority.

[0054] Furthermore, the priority determination unit 142 acquires a plurality of pieces of screen display information currently being displayed on the display device 40 and their layouts (S204).

[0055] The priority determination unit 142 determines the display priority of each screen display information based on one or more pieces of warning screen information associated with the warning information and their display priority, and on the multiple pieces of screen display information currently displayed on the display device 40 and their layout (S205). The priority determination unit 142 determines whether warning screen information, which is a screen related to the generated warning, is included in the layout currently displayed on the display device 40, that is, by comparing the currently displayed screen display information with the warning screen information, whether warning screen information associated with the warning information is not included in the currently displayed screen display information, and whether there is warning screen information that should be prioritized for display over the currently displayed screen display information. If it is determined that the warning screen information is included in the screen display information, or there is no warning screen information that should be prioritized for display over the currently displayed screen display information (YES in S205), the currently displayed screen display information and layout are not changed, and the process returns to step S101. On the other hand, if it is determined that the alarm screen information is not included in the screen display information, or that there is alarm screen information that should be given priority for display over the currently displayed screen display information (NO in S205), the alarm screen information is to be replaced with the currently displayed screen display information, and the process transitions to STEP 2 in FIG. 9.

[0056] In step S205, if it is determined that the warning screen information is not included in the screen display information, or that there is warning screen information that should be given priority over the currently displayed screen display information, the warning screen information is replaced with the currently displayed screen display information, and the process proceeds to step S308 of STEP 2 (S103) in Fig. 9. Meanwhile, in STEP 2, a determination is made by the display determination unit 143. The display determination unit 143 performs each of the determinations of steps S301, S304, and S306 in parallel.

[0057] In step S301, the display determination unit 143 determines whether or not there is a monitor displaying an outside world image in the display device 40. If there is a monitor displaying an outside world image (YES in S301), the process proceeds to step S302. On the other hand, if there is no monitor displaying an outside world image (NO in S301), the process proceeds to step S308.

[0058] In step S302, the display determination unit 143 determines whether or not there is a target in the outside world image. The display determination unit 143 determines whether or not there is a target based on target information from an electronic chart, target information from an AIS (Automatic Identification System), a navigation radar, and the like. The display determination unit 143 sets the screen display information by a camera capturing a direction (relative direction) where there are many dangerous targets to be not a switching target based on the target information from the electronic chart, and sets the display of the target screen display information to be essential. Also, based on target information from the AIS, and the like, sets the screen display information by a camera capturing a direction (relative direction) where there are many targets to be not a switching target, and sets the display of the target screen display information to be essential. If the display determination unit 143 determines that there is a target (YES in S302), the process proceeds to step S303. On the other hand, if it determines that there is no target (NO in S302), the process proceeds to step S308. In this way, by determining whether or not it is necessary to display the screen display information depending on the presence or absence of a landmark, it is possible to optimize the content of the information provided (recommendation).

[0059] In step S303, the display determination unit 143 determines whether or not there is a risk of collision between the ship and the target determined to be "present" in step S302. If it is determined that there is a risk of collision with the target (YES in S303), the process proceeds to step S305. On the other hand, if it is determined that there is no risk of collision with the target (NO in S303), the process proceeds to step S308.

[0060] If it is determined in step S303 that there is a risk of collision with a target, the screen display information captured by a camera capturing the target or a direction in which there are many targets is not subject to switching, and the target screen display information is excluded from the target of information provision so that display of the target screen display information is required. The display determination unit 143 removes the monitor corresponding to the relevant screen display information from the monitors capable of switching the layout, changes the number of monitors capable of switching the layout (S305), and transitions to step S308.

[0061] 9, the display determination unit 143 acquires monitor failure information and determines whether or not there is a failed monitor. If it is determined that there is a failed monitor (YES in S304), the process proceeds to step S305. On the other hand, if it is determined that there is no failed monitor (NO in S304), the process proceeds to step S308.

[0062] If it is determined in step S304 that there is a faulty monitor, the faulty monitor is removed from the monitors for which layout switching is possible since it cannot be used, and the number of monitors for which layout switching is possible is changed (S305), and the process proceeds to step S308.

[0063] In step S306 of Fig. 9, the display determination unit 143 determines whether there is any screen information that cannot be currently displayed. The determination in step S306 is performed to check whether data that is the source of the screen information exists, for example, in the case where a malfunction has occurred in a device such as a camera for acquiring the screen information and the data itself does not exist. If it is determined that there is any screen information that cannot be currently displayed (YES in S306), the process proceeds to step S307. On the other hand, if it is determined that there is no screen information that cannot be currently displayed (NO in S306), the process proceeds to step S308.

[0064] If it is determined in step S306 that there is screen information that cannot be currently displayed, the screen information that cannot be displayed is not subject to switching since it is unusable, and is therefore excluded from the information provided (S307), and the process proceeds to step S308.

[0065] In step S308, the information providing unit 144 selects a group of screen information and warning screen information based on the determination result of the priority determination unit 142 in STEP 1 of Fig. 7 and the determination results of the display determination unit 143 in STEP 2 of Fig. 9, and further generates a layout for this group to be presented to the user. The information providing unit 144 acquires a doctrine for providing information from a database DB2 in which the doctrine is registered, and generates a layout of screen information for which switching is proposed based on the doctrine for providing information. The layout of the screen information for which switching is proposed includes warning screen information.

[0066] When the information providing unit 144 generates a layout of screen information for suggesting switching to be presented to the user in step S308, the process proceeds to step S104 in FIG.

[0067] 6, the layout of the screen information proposed to be switched is presented to the user, and the user (operator) selects whether to adopt the layout or reject the adoption of the layout. The layout of the screen information proposed to be switched is presented, for example, by displaying it on the table console 12. The user (operator) selects whether to adopt the layout proposed by the display control device 14 on the touch panel 12a. The user (operator) may also select whether to adopt the layout proposed by the display control device 14 on the consoles 22-1 to 22-3 and 32-1 to 32-17.

[0068] If the user selects to adopt the proposed layout in step S104, the process proceeds to step S105, where an instruction is given to the display control device 14 to change to the adopted layout.

[0069] In parallel with step S105, in step S106, the adoption or rejection of the layout proposed in step S104 is recorded in a log. After the processes of steps S105 and S106 are performed, the process returns to step S101.

[0070] To provide a display device 40 capable of displaying a plurality of screen information, in the case where the number of screen information is large and the screen information is diverse, a user must dynamically and manually select the screen information to be displayed on the display device 40 according to the situation, and instantaneous judgment is required for a huge amount of information. According to this embodiment, the optimal screen display information (alarm screen information) corresponding to the generated alarm is narrowed down and the information is provided (recommended), so that the user can easily select the screen information. In addition, when an irregular event occurs due to an alarm, the necessary screen display information is selected and presented, so that the effort and time required for the user to make a decision can be reduced.

[0071] According to this embodiment, a two-stage evaluation of priority judgment and display judgment is performed on screen display information, so that calculation resources can be optimized.

[0072] <Additional Notes> The display control device, the division command system, the ship, the display control method, and the display control program described in the above-described embodiments can be understood, for example, as follows.
