  Next, embodiments of the present invention will be described with reference to the drawings. First, the overall configuration of the BNWAS according to the present embodiment will be described with reference to FIGS. 1 to 3. FIG. 1 is a block diagram showing an overall configuration of a BNWAS 1 according to an embodiment of the present invention. FIG. 2 is a front view of the bridge alarm device 11. FIG. 3 is a front view of the reset device 12 and the cabin alarm device 13.

  The BNWAS (Navigation Watch Warning Device) 1 keeps confirming that the operations are being performed by the officer of the duty on duty, and if the confirmation cannot be taken for a certain period of time due to the sleepiness of the officer on duty or poor physical condition, etc. It is a device for generating an alarm and notifying other navigators. In addition to the duty officer on duty, the officer includes a navigator as a substitute (back up officer) and a navigator taking a break. An alternative officer is an officer who performs steering instead of when the duty officer on duty is complaining of poor physical condition. In addition, based on the work schedule or the like, at which time which navigator becomes the substitute navigator is preset in BNWAS1.

  When it is not possible to confirm that the duty officer on duty is performing the work for a certain period of time or longer, an alarm is first generated in the cabin of the substitute officer (cabin) and the canteen. After that, if the confirmation cannot be taken for a certain period of time, an alarm is also generated in the cabin of the officer who is taking a break. In this way, the BNWAS 1 gradually increases the places where alarms are generated. In the following description, this stage is referred to as a stage.

  In addition, the BNWAS 1 of the present embodiment can select three types of modes: MANUAL ON, MANUAL OFF, and AUTO. MANUAL ON is a mode in which the watch officer on duty is always monitored, and MANUAL OFF is a mode in which the watch officer on duty is not always monitored. The AUTO is a mode in which the watch officer on duty is monitored when steering by the automatic steering device is performed, and the supervisor on duty is not monitored when steering by the automatic steering device is not performed. This is because when the steering is being performed by the automatic steering device, there is little work for the officer on duty and it is easy to fall asleep.

  As shown in FIG. 1, the BNWAS 1 includes a bridge alarm device (notification device) 11 and a reset device (external device) 12 installed in a bridge (steering cabin), and a cabin alarm device (installed in each navigator's cabin) ( An alarm device 13 and a public alarm device (alarm device) 14 installed in a common area such as a cafeteria and a corridor are provided as main components. These components are connected via the alarm control unit 10 and can transmit and receive various signals such as an alarm signal for generating an alarm. Further, an automatic steering device (external device) 15 and a radar device (external device) 16 are connected to the BNWAS 1 via the alarm control unit 10. In FIG. 1, only one cabin alarm device 13 and one public alarm device 14 are shown, but a plurality of cabin alarm devices are actually arranged. Hereinafter, each configuration connected to the BNWAS 1 will be described.

  As shown in FIGS. 1 and 2, the bridge alarm device 11 includes a control unit 31, an operation unit 32, a display unit 33, and an alarm buzzer 34. The control unit 31 mainly controls the stage, and includes a stage control unit 311, a count unit 312, a reset unit 313, and a display control unit 314.

  The counting unit 312 counts the time from when it can be confirmed that the officer is performing business, and outputs a signal to the stage control unit 311 when this count exceeds a predetermined number. Receiving this signal, the stage controller 311 advances the stage to the next stage. Further, the stage control unit 311 sends an alarm signal to the alarm device set according to the stage among the reset device 12, the cabin alarm device 13 and the public alarm device 14 via the transmission / reception unit (transmission unit) 35. Configured to send. The reset device 12, the cabin alarm device 13, and the public alarm device 14 that have received this warning signal generate a warning. The display control unit 314 performs control to change the display content of the display unit 33 when the stage proceeds to the next stage.

  In addition, when it is confirmed that the officer is performing work, the reset unit 313 transmits a reset signal to the stage control unit 311 and the count unit 312. The stage control unit 311 that has received the reset signal is configured to return (reset) the stage to the initial stage (stage where no alarm is generated). The count unit 312 that has received the reset signal is configured to return the count to 0 (reset). In the following description, a process in which the reset unit 313 transmits a reset signal to cause the stage control unit 311 and the count unit 312 to perform the above reset may be referred to as a “reset process”. The specific stage set in the stage control unit 311 and the control performed by the display control unit 314 according to this stage will be described later.

  As shown in FIG. 2, the operation unit 32 includes six keys and a cross key. By operating these keys according to the display on the display unit 33, various settings of the BNWAS 1 can be performed. When the operation unit 32 is operated, it is determined that the officer on duty is performing the business, and reset processing is performed.

  As shown in FIG. 2, the display unit 33 includes a header unit 331, a transmission destination display unit 332, a footer unit 333, and a timer display unit 334. The display color in the display unit is assumed to be displayed with a black background color (white in the figure) and a white character color (black in the figure) unless otherwise specified.

  From the left side of FIG. 2, the mode, power supply state, and operation confirmation mark set in BNWAS 1 are displayed on the header portion 331. As the mode, a mode selected from the above-described three modes (AUTO in FIG. 2) is displayed. The power status indicates which DC or AC power source is connected to BNWAS 1 (both DC and AC power sources are connected in FIG. 2). The operation confirmation mark is a display for displaying whether or not BNWAS1 is operating normally. When BNWAS1 is operating normally, eight points shown in FIG. 2 are rotated.

  In the transmission destination display section 332, the name of the navigator is displayed. And the underline is displayed on the name of the officer set as an alternative officer. The display unit 33 in FIG. 2 displays that the chief officer has been set as an alternate officer. As described above, in the control unit 31 included in the BNWAS 1, it is set which navigator is to be an alternative navigator at which time, and the display control unit 314 determines which navigator is based on this setting. It automatically switches whether the name is underlined.

  The footer unit 333 displays system malfunctions, operation guides, alarm messages, and the like according to the situation. In addition, when it becomes necessary to display a plurality of messages at the same time, only high priority information can be displayed, or a plurality of messages can be displayed alternately.

  The timer display unit 334 displays time (remaining time) using a bar-shaped symbol (bar) until the stage switches to the next stage. The bar is shortened as the remaining time decreases. The color of the bar is changed according to the stage under the control of the display control unit 314.

  The bridge alarm device 11 can generate an alarm message by the footer unit 333 of the display unit 33 and can generate an alarm sound by the alarm buzzer 34.

  Next, the reset device 12 will be described. As shown in FIGS. 1 and 3A, the reset device 12 includes a reset button 41 for performing a reset process, an alarm lamp 42, and an alarm buzzer 44. The reset device 12 is connected to the control unit 31 via the transmission / reception unit 45, the alarm control unit 10, and the transmission / reception unit 35, and can transmit and receive signals.

  The officer on duty can perform the reset process not only by the operation unit 32 of the bridge alarm device 11 but also by the reset button 41 of the reset device 12. Thereby, it is not necessary to move to the vicinity of the bridge alarm device 11 every time in order to perform the reset process. Further, when the reset processing is performed by the bridge alarm device 11, it is necessary to operate the key while looking at the bridge alarm device 11 so as not to change the setting by mistake. On the other hand, since only the reset button 41 is installed in the reset device 12 as an operable configuration, the reset process can be performed without looking at the reset device 12.

  The alarm lamp 42 and the alarm buzzer 44 can generate an alarm when an alarm signal is received from the stage control unit 311.

  As shown in FIGS. 1 and 3 (b), the cabin alarm device 13 includes an alternative officer display lamp 51, a warning lamp 52, and a warning buzzer 54. The cabin alarm device 13 is connected to the control unit 31 via the transmission / reception unit 55, the alarm control unit 10, and the transmission / reception unit 35, and can transmit and receive signals.

  The cabin alarm device 13 is installed in the cabin of each navigator as described above. Further, in the cabin alarm device 13 of the aviator who is set as the substitute aviator, the substitute aviator display lamp 51 is lit. Thereby, the officer can confirm whether he is an alternative officer or not.

  The alarm lamp 52 and the alarm buzzer 54 can generate an alarm when an alarm signal is received from the stage control unit 311.

  As shown in FIG. 1, the public alarm device 14 includes a warning lamp 62 and a warning buzzer 64. Note that the appearance of the public alarm device 14 is the same as the appearance of the cabin alarm device 13 in which the substitute officer display lamp 51 is removed, and thus the illustration is omitted. The public alarm device 14 is connected to the control unit 31 through the transmission / reception unit 65, the alarm control unit 10, and the transmission / reception unit 35, and can transmit and receive signals.

  The alarm lamp 62 and the alarm buzzer 64 can generate an alarm when an alarm signal is received from the stage control unit 311. In addition, a device used as the cabin alarm device 13 (the device shown in FIG. 3B) can be used as the public alarm device 14. In this case, since the substitute officer display lamp 51 is not required, a configuration in which the alternate officer display lamp 51 is always turned on or a configuration in which it is always turned off may be used. Thereby, the kind of components can be reduced.

  The automatic steering device 15 maintains the traveling direction of the ship toward a set destination even under the influence of disturbances such as waves and winds, and automatically navigates a preset route. Is to do. When an operation such as a setting change is performed on the automatic steering device 15, it is determined that the officer on duty is performing a task, and a reset process is performed.

  The radar device 16 can radiate a transmission signal, and is configured to receive a reflected wave from a target (for example, land or other ship on the sea) around the ship as a reception signal. The radar device 16 can display the position and shape of the target using the received signal. It should be noted that even when an operation such as a setting change is performed on the radar device 16, it is determined that the officer on duty is performing the work, and the reset process is performed.

  As described above, the reset unit 313 performs the reset process (the stage of the stage control unit 311) based on the operation performed by the duty officer on the external devices such as the reset device 12, the automatic steering device 15, and the radar device 16. And a process of resetting the count of the count unit 312).

  Next, details of the stage set in the stage control unit 311 and display contents of the display unit in each stage will be described. First, an outline of each stage will be described with reference to FIGS. 4 and 5. FIG. 4 is an explanatory diagram showing the relationship between the elapsed time after the reset process and the stage. FIG. 5 is a table showing the operation status of each alarm device in each stage.

  As shown in FIG. 4, the stage control unit 311 is set with a normal stage, an alarm notice stage, a first alarm stage, a second alarm stage, and a third alarm stage. Then, the stage advances to the next stage when the time (set time) shown below each stage in FIG. 4 has elapsed without performing the reset process. The third alarm stage is the last stage, and since the next stage is not set, this time is not shown.

  Moreover, the alarm device etc. which operate | move in each stage are shown in FIG. The above stage is described in the first line in FIG. On the other hand, the alarm device provided in BNWAS 1 is described in the first column in FIG. 5, and the configuration provided in the alarm device is described in the second column. In each stage, a configuration for performing an alarm or the like is indicated by a circle. In FIG. 5, two cabin alarm devices 13 are displayed. However, in the cabin alarm device 13 that is displayed as an alternative aviator, an alternative aviator is set, and the cabin of the alternative aviator is displayed. is set up. On the other hand, the cabin alarm device 13 that is displayed as “other” is not set as a substitute aviator, and is installed in the cabin of the officer on duty or resting. In order to notify that the cabin alarm device 13 installed in the cabin of the alternate officer is an alternate officer, the alternate officer display lamp 51 of the cabin alarm device 13 is always lit.

  Next, the operation of each alarm device in the normal stage will be described with reference to FIG. FIG. 6 is a diagram showing the display contents of the display unit 33 in the normal stage.

  The normal stage is a stage indicating that there is no abnormality, and as shown in FIG. 4, 12 minutes after the reset process is performed becomes the normal stage. At this normal stage, as shown in FIG. 5, no alarm is generated.

  Immediately after the reset process is performed, the remaining time until switching from the normal stage to the next stage is 12 minutes, and the display unit 33 in this case is displayed as shown in FIG. In the normal stage, the display unit 33 is controlled by the display control unit 314 so that the bar displayed by the timer display unit 334 is blue.

  Further, from the time shown in FIG. 6 (a), the control unit 31 when about 5 minutes have passed without the reset process and the remaining time becomes a little as 7 minutes is as shown in FIG. 6 (b). Become. Thus, in order to show that the remaining time has decreased, the display control unit 314 shortens the bar from the upper side, but this is reminiscent of an hourglass. You can intuitively understand that it will decrease. If the remaining time in the normal stage becomes 0 without performing the reset process, the stage proceeds to the warning notice stage.

  Next, the operation of each alarm device in the warning notice stage will be described with reference to FIGS. 4, 5, and 7A. FIG. 7A is a diagram showing the display content of the display unit 33 immediately after the stage has advanced to the warning notice stage.

  The warning notice stage is a stage for notifying that a full-scale warning will occur, and as shown in FIG. 4, 15 seconds after the remaining time in the normal stage becomes zero becomes the warning notice stage. In this warning notice stage, as shown in FIG. 5, a warning is generated by the display unit 33 of the bridge alarm device 11 and the warning lamp 42 of the reset device 12. In other words, at the warning notice stage, only a visual warning in the bridge is generated. Thereby, it is possible to notify the officer on duty that the reset process has not been performed.

  FIG. 7A shows the display content of the display unit 33 immediately after proceeding to the warning notice stage. In FIG. 7A, a bar indicating the remaining time of 15 seconds is displayed on the timer display unit 334 and an alarm message is displayed on the footer unit 333. In the warning notice stage, the display unit 33 is controlled by the display control unit 314 so that the bar and the warning message are yellow. Then, when the remaining time in the warning notice stage becomes 0 without performing the reset process, the stage proceeds to the first warning stage.

  Next, the operation of each alarm device in the first alarm stage will be described with reference to FIG. 4, FIG. 5, and FIG. 7 (b). FIG. 7B is a diagram showing the display content of the display unit 33 immediately after the stage has advanced to the first alarm stage.

  After the first alarm stage, a full-scale alarm is generated. As shown in FIG. 4, the first alarm stage is 15 seconds after the remaining time in the alarm notice stage becomes zero. In the first alarm stage, as shown in FIG. 5, an alarm is generated by the alarm buzzer 34 of the bridge alarm device 11 and the alarm buzzer 44 of the reset device 12 in addition to the alarm generated at the alarm notice stage. That is, in the first alarm stage, an audible alarm is generated in addition to the visual alarm in the bridge. Thereby, even when the duty officer on duty is asleep, it is possible to wake up and notify that the reset process has not been performed.

  The display content of the display unit 33 immediately after proceeding to the first alarm stage is shown in FIG. In FIG. 7B, a bar indicating the remaining time of 15 seconds is displayed on the timer display unit 334 and an alarm message is displayed on the footer unit 333. Further, from the first alarm stage to the third alarm stage, the display unit 33 is controlled by the display control unit 314 so that the bar and the alarm message are red.

  In this way, the display colors of blue, yellow, red and bars and characters are changed as the level of urgency of the stage increases. This change in display color is very similar to the color change of traffic lights, etc. Yes. In this way, since the image that a person normally has is taken into consideration for the color, the degree of urgency can be intuitively grasped. Then, when the remaining time in the first alarm stage becomes 0 without performing the reset process, the stage proceeds to the second alarm stage.

  Next, the operation of each alarm device in the second alarm stage will be described with reference to FIG. 4, FIG. 5, and FIG. FIG. 8A is a diagram showing the display content of the display unit 33 immediately after the stage has advanced to the second alarm stage.

  As shown in FIG. 4, the second alarm stage is 180 seconds after the remaining time in the first alarm stage becomes zero. In this second alarm stage, as shown in FIG. 5, in addition to the alarm generated at the time of the first alarm stage, the alarm by the alarm lamp 52 and the alarm buzzer 54 of the cabin alarm device 13 in which an alternative officer is set The alarm by the alarm lamp 62 and the alarm buzzer 64 of the public alarm device 14 is generated. In other words, in the second alarm stage, the cabin alarm device 13 notifies the alternate officer, and the public alarm device 14 also issues an alarm in consideration of the presence of the alternate officer in a common space for meals and the like. Is generated. As a result, even when the on-duty officer becomes unable to steer due to poor physical condition or the like, the alternate officer can be called to the bridge to perform steering correction and reset processing.

  The display content of the display unit 33 immediately after proceeding to the second alarm stage is shown in FIG. In FIG. 8A, a bar indicating the remaining time of 180 seconds is displayed on the timer display unit 334 and an alarm message is displayed on the footer unit 333. In the second alarm stage and the third alarm stage, the reset process can be performed only by the reset key of the operation unit 32 of the bridge alarm device 11, and this is also displayed in the alarm message. Then, when the remaining time in the second alarm stage becomes 0 without performing the reset process, the stage proceeds to the third alarm stage which is the final stage.

  As described above, the second warning stage also generates a warning for the substitute officer. Since the control unit 31 of this embodiment is set with which navigator to be the substitute navigator at which time, the control unit 31 issues an alarm to which navigator at the second alarm stage. It is automatically switched according to the time.

  Next, the operation of each alarm device in the third alarm stage will be described with reference to FIG. 4, FIG. 5, and FIG. FIG. 8B is a diagram showing the display content of the display unit 33 in the third alarm stage.

  As shown in FIG. 4, the third alarm stage is from when the remaining time in the second alarm stage becomes zero until the reset process is performed. In this third alarm stage, as shown in FIG. 5, in addition to the alarm generated at the second alarm stage, the alarm by the alarm lamp 52 and the alarm buzzer 54 of the cabin alarm device 13 in which no substitute aviator is set. Will occur. That is, in the third alarm stage, notification is made to all navigators. As a result, even when the alternate officer cannot respond to the alarm, the resting officer can be called to the bridge and the steering correction and reset processing can be performed. In addition, even when the substitute officer is heading for the bridge in response to the alarm, if the taking-over officer can go to the bridge more quickly, the steering correction and reset processing can be performed more quickly. it can.

  The display content of the display unit 33 in the third alarm stage is shown in FIG. In the third stage, since there is no concept of remaining time, no bar is displayed on the timer display unit 334.

  In this way, by using the BNWAS 1 of the present embodiment, when the duty officer on duty is falling asleep, it is possible to notify other officers in an appropriate order, and to the officer who has seen the display unit 33. It is possible to instantly grasp the current urgency level and the remaining time until the next stage.

  As described above, when the mode is AUTO and the steering by the automatic steering device 15 is not performed, and when the mode is MANUAL OFF, the watch officer on duty is not monitored. That is, the stage does not progress. The display at this time is shown in FIG. FIG. 9A is a diagram illustrating the display contents of the display unit 33 when the mode is AUTO and the steering by the automatic steering device 15 is not performed. FIG. 9B is a diagram showing the display content of the display unit 33 when the mode is MANUAL OFF.

  Further, in the bridge alarm device 11 of the present embodiment, the stage control unit 311 generates a normal stage indicating normality, an alarm notice stage indicating a pre-stage of a full-scale alarm, and an alarm. First to third alarm stages indicating stages are set. The display control unit 314 uses a blue display color for the normal stage, yellow for the warning notice stage, and red for the warning stage, and displays the change status (specifically, the remaining time until proceeding to the next stage) and the warning message. It is displayed on the display unit 33.

  Thereby, since the display color of the change situation is set in consideration of the color image normally recognized by a person, the navigator who has seen the display unit 33 can intuitively know the current urgency level. Also, by displaying the remaining time, it is possible to know the time until the next stage alarm occurs, so it is possible to grasp the urgency more accurately than the configuration that displays the elapsed time at the current stage. Can do.

  In the bridge alarm device 11 of the present embodiment, the reset unit 313 resets the stage and the count based on the operations of the reset device 12, the automatic steering device 15, and the radar device 16.

  As a result, the reset process can be performed by the reset button 41 of the reset device 12, so that the officer on duty can perform the reset process from other than the place where the bridge alarm device 11 is installed. In addition, since the reset process can be performed by the automatic steering device 15 and the radar device 16, it can be confirmed that the supervisor on duty is not taking a nap without performing a special operation.

  Further, the bridge alarm device 11 of the present embodiment includes a transmission / reception unit 35 that transmits an alarm signal for operating the alarm lamps 42, 52, 62 and the alarm buzzers 44, 54, 64. The display unit 33 displays the name of the cabin navigator to whom the warning signal is transmitted.

  As a result, when the duty officer on duty is asleep and does not steer for a while, other officers can be notified. Moreover, the officer on duty who has seen the display unit 33 can know who is another officer who can be notified.

  In the bridge alarm device 11 of the present embodiment, the transmission destination of the alarm signal is changed for each stage.

  As a result, when a long time has passed since the officer on duty has fallen asleep, it is possible to promptly bring the officer to the bridge by operating many alarms and notifying many officers. Therefore, the course can be corrected and obstacles can be avoided quickly.

  Moreover, in the bridge alarm device 11 of the present embodiment, the display unit 33 displays a plurality of names of navigators to which an alarm signal is transmitted in any stage, and among the navigators, the second alarm stage Underline and highlight the name of the substitute officer who will send the warning signal.

  As a result, the officer on duty who looks at the display unit 33 can immediately confirm which officer is the substitute officer. Therefore, if another officer is mistakenly set as an alternative officer, the on-duty officer can quickly notice and correct the setting.

  Further, in the bridge alarm device 11 of the present embodiment, the transmission destination of the alarm signal is automatically switched according to the time.

  Thereby, it is not necessary to manually switch the transmission destination of the alarm signal by setting the duty status of the on-board officer and the substitute officer in advance, and the processing performed by the user can be reduced.

  Next, a first modification of the above embodiment will be described with reference to FIGS. FIG. 10 is a diagram illustrating display contents of the display unit 33 in the normal stage and the warning notice stage according to the first modification. FIG. 11 is a diagram illustrating display contents of the display unit 33 in the first alarm stage and the second alarm stage according to the first modification. In the following description of the modified examples, the same or similar members as those in the above-described embodiment may be denoted by the same reference numerals in the drawings, and the description thereof may be omitted.

  In the configuration of the above embodiment, the time indicated by one scale on the timer display unit 334 is the same throughout each stage. However, in this modification, the time indicated by one scale on the timer display unit 334 can be changed for each stage. It is configured. In addition, the display control unit 314 of this modification is configured to be able to change the number displayed beside the scale of the timer display unit 334. Then, the time indicated by one scale of the timer display unit 334 and the numbers displayed beside the scale are changed for each stage.

  This will be specifically described below. As shown in FIG. 10A, in the normal stage, the display is the same as that in the above embodiment except that “min” is displayed beside the display of 0 on the timer display unit 334. This min indicates minute. Then, when the stage becomes the warning notice stage, as shown in FIG. 10 (b), the min changes to sec, and the place where 5 is displayed in the normal stage is 10 and 10 is displayed. Changes to 20. This sec indicates second (second). That is, in the normal stage, one scale on the timer display unit 334 indicates 1 minute, but in the alarm notice stage, one scale on the timer display unit 334 indicates 2 seconds.

  Similarly, as shown in FIG. 11A, in the first alarm stage, one scale on the timer display unit 334 indicates 2 seconds. In addition, as shown in FIG. 11B, in the second alarm stage, one scale on the timer display unit 334 indicates 15 seconds.

  With this configuration, the remaining time in each stage can be displayed in an easily viewable manner.

  Next, a second modification of the above embodiment will be described with reference to FIG. FIG. 12 is a diagram illustrating display contents of the display unit 33 according to the second modification.

  In the above embodiment and the first modification, the remaining time is displayed with a different bar for each stage, but in this modification, the remaining time is displayed with one bar through the stage. In the present modification, the bar positioned above 0 on the scale of the timer display unit 334 indicates the remaining time in the normal stage, and the bar positioned below 0 indicates the remaining time in the other stages. .

  That is, when the reset process is not performed, the blue bar shown in FIG. 12 becomes shorter. When the bar becomes shorter than 0 on the scale of the timer display unit 334 (the blue portion of the bar disappears), the warning notice stage is set. Thereafter, when the yellow portion of the bar disappears, the first alarm stage is set, and when the bar length becomes a predetermined length or less, the second alarm stage is set. The third alarm stage is performed after the bar is not displayed.

  The preferred embodiments and modifications of the present invention have been described above, but the above configuration can be modified as follows, for example.

  In the above-described embodiment and the modification, the timer display unit 334 displays the time until switching to the next stage as the current stage change state, but instead of this, it has elapsed since switching to the current stage. The timer display unit 334 may display the measured time.

  In the said embodiment and modification, blue, yellow, and red were used as a display color which shows remaining time, However, The effect of this invention can be exhibited even if it uses colors other than these colors. In particular, green may be used instead of blue. Further, although black is used as the background color and white is used as the character color, other colors may be used as the background color and the character color.

  As the time until the stage proceeds to the next stage, the values used in the embodiment and the modification are examples, and an appropriate time can be used. In particular, the time from the normal stage to the warning notice stage can be selected from 3 minutes to 12 minutes, or the time from the second alarm stage to the third alarm stage can be selected from 90 seconds to 180 seconds. Can be made selectable.

  In the above embodiment and the modification, five stages are set, but the number of stages is arbitrary, and can be, for example, three stages and four stages. Further, FIG. 5 shows a correspondence relationship between a stage and an alarm performed at the stage, but what alarm is performed at any stage is arbitrary.

  In the above embodiment and the modified example, when the mode is AUTO, it is configured to switch whether or not to monitor the watch officer on duty depending on the operation status of the automatic steering device 15, but instead, the following A configuration can be used. That is, the alarm control unit 10 includes a device (navigation device or the like) that stores position information (longitude and latitude, etc.) of the port and a device (GPS device or the like) that can acquire the current location (longitude and latitude, etc.) of the ship. When the ship is determined to be close to the port by these devices, the system is switched so that the watch officer on duty is not monitored. Moreover, it is good also as a structure which equips with a ship speedometer and switches so that a supervisor on duty may be monitored when a ship speed becomes a value more than predetermined.

  In the above embodiment and the modification, the example in which the notification device is applied to the BNWAS has been shown. However, in addition to the BNWAS as long as the check is required every predetermined time and the notification is performed when the check is not performed. The present invention can be applied.
