Voices that respond to reports from (eg high, yes, o
(K, understanding, etc.) is input to the headphone type microphone 11, the work monitoring device 6 is wirelessly notified,
Employment status is monitored based on this report confirmation.

[0020] Usually, the shift staff is set up to check the ship's position while the ship is sailing, and to monitor obstacles (ships, shallows, etc.) to prevent grounding and collisions. Route maintenance work to maintain geographical position and time schedule according to the route, when it is necessary to change the course and ship speed, vessel operation when dangerous areas such as dangerous ships and shallows are found by monitoring work The work at Funabashi, such as work, is diverse and always busy.

In the work monitoring device 6 of the navigation support system according to the present embodiment, data of a collision / grounding hazard report or scheduled report with the watchman (nautical officer) and a response to each report are wirelessly transmitted and received. By using the voice input method through the headphone type microphone 11, the working confirmation can be performed anytime and anywhere.

Next, the operation of the navigation support system in this embodiment will be described with reference to the flowchart shown in FIG. 1. Output of information on dangers such as grounding or collision to shift staff (collision / grounding hazard report).

ARPA (collision preventive device) 1 measures TCPA (closest approach time) and DCPA (closest approach distance) between another ship and the ship in flight, and there is a risk of collision with another ship. Is notified of the collision risk information to the work monitoring device 6.

On the other hand, the grounding prevention device 5 compares the heading from the gyro 2, the ship speed from the speedometer 3, and the own ship position from the positioning device 4 with the route database 7 to determine the risk of grounding. If there is a grounding risk , the worker monitoring device 6 is notified of the grounding danger information .

When the work monitoring device 6 receives the collision danger information from the ARPA 1 or the grounding danger information from the grounding prevention device 5 (step S2), the report contents as shown in FIG. The grounding danger information or the collision danger information according to the report, the report on the collision risk ship, the report on the grounding danger area) is transmitted to the voice output device 9 and the information display device 8 (step S6).

The voice output device 9 outputs a voice (contents of the voice output shown in FIG. 2) according to the electrically prepared report contents in accordance with the grounding danger information or the collision danger information transmitted from the work monitoring device 6. Output.

The information display device 8 is the work monitoring device 6
The danger information is displayed on the display screen in accordance with the grounding danger information or the collision danger information transmitted from. When the shift officer (the officer) is in the control room in which the information display device 8 and the voice output device 9 are installed, he / she can also respond by operating buttons on the device (step S8).

Further, even when the shift officer (nautical officer) leaves the control room, since the wireless headphone type microphone 10 is attached, the grounding danger information or the collision danger information is reported in the control room. The notification is made by a voice having the same content as that of the voice output device 9 in the inside.

When the watchman (a navigator) who listens to the voice of the report contents from the work monitoring device 6 through the headphone type microphone 11 responds with a voice (high, yes, OK, OK, etc.), the report confirmation is wirelessly transmitted. Accordingly, the work monitoring device 6 receives it.

That is, even if the shift officer (nautical officer) cannot check the display of the information display device 8 and operate the button when he / she is not in the control room or is busy with other work, he / she speaks a voice. You can easily notify the confirmation of the report just by doing.

The work monitoring device 6 continues to perform the same monitoring as described above when the report confirmation of the report of the grounding danger information or the collision danger information is received. On the other hand, the work monitoring device 6 uses the loudspeakers 10a and 10b in the control room, cockpit, captain's cabin, etc., when there is no report confirmation due to the absence of work by the shift attendant due to sudden illness, dozing, accident, etc. An abnormal working alarm is output to notify a person other than the on-duty member of the risk of collision / grounding (step S10).

As described above, by making it possible for the shift officer (navigation officer) to reliably notify the collision / grounding danger report wherever, it is possible to avoid the danger of grounding / collision due to negligence in the watch operation. In addition, even if there is a situation in which the staff does not confirm the report due to a sudden illness, dozing, an accident, etc., an alarm for working abnormality will be issued to other persons in the control room, cockpit, captain's room, etc. Therefore, it is possible to avoid the danger of grounding and collision.

2. Providing information to shift staff at regular intervals (annual report). The work monitoring device 6 provides information (regular report) at regular time intervals (β). The work monitoring device 6 is a grounding prevention device 5
2 based on the heading from the gyro 2 and the ship speed from the speedometer 3, as well as the current route data from the route database 7 and various information obtained from the position of the ship from the positioning device 4, as shown in FIG. Such report contents (scheduled report start report,
Information of the navigation status report, the next change point arrival schedule report, the off-course / off-track report) is transmitted to the voice output device 9 and the information display device 8 (step S7). That is, the work monitoring device 6 regularly sets the distance to the next change point, the estimated arrival time at the next change point, the off-use (unit: degree) indicating the deviation from the current route, the off-track (unit: mile) value, etc. Audio output as a report.

In response to the information provided in the scheduled report, the shift staff receives a voice report through the headphone type microphone 11 as in the case of the collision / grounding hazard report described above, and also reports this report by voice. It can be confirmed (step S8).

When there is a report confirmation for the regular report, the work monitoring device 6 continues to monitor the same as the above while measuring the regular report output interval (steps S9, S4, S5).

On the other hand, when the watch staff does not confirm the report from the headphone type microphone 11, the work monitoring device 6 judges that there is some abnormality in the work status of the shift staff, and the control room, cockpit, captain's room, etc. In step S10, an abnormal working alarm is output to notify a person other than the on-duty staff of the risk of collision / grounding (step S10).

In this way, the work monitoring is performed by using the voice input format of the headphone type microphone 11 to check the position of the own ship in the bridge and the obstacles to prevent the grounding / collision in advance. Ships and shallows)
Lookout work to monitor ships, route maintenance work to maintain geographical position and time schedule according to the set route, and when it is necessary to change the course and ship speed, the monitoring work will help to monitor dangerous ships and shallow water. The on-duty staff, who are constantly busy in a wide variety of operations, such as when maneuvering when a dangerous area is found, can easily confirm employment anytime and anywhere, rather than the conventional manual operation confirmation on the screen. The burden can be reduced and the working status can be monitored reliably.

[0038]

As described above in detail, according to the present invention, it is possible to confirm the screen display or press the button by the manual operation in order for the shift officer (the officer) who is the target of the work monitoring to perform other duties. Even in situations where it is not easy to do, the work monitoring device can reduce the work load on the shift attendant because the information provided from the work monitoring device (various reports) can be notified by voice and the report confirmation can be notified by voice response. Labor monitoring becomes possible.
