[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention collects sound such as a horn outside the ship in the steering room of the ship, and makes it possible to recognize the presence of this external sound in the steering room, thereby determining whether or not another ship is approaching. The present invention relates to an external audible warning device for a ship, by which it is possible to easily confirm with the ears or eyes whether the ship is approaching from the left or right (or from the front or back).

[0002]

[Prior art]

 Conventionally, steering when a ship is not in sight, such as night navigation or fog navigation, is performed mainly by radar and visual inspection to determine whether another ship is approaching and from which direction it is approaching. Information such as whether or not it is obtained (generally, since the steering room of a ship is closed, almost no sound such as a horn from an approaching ship is heard).

[0003]

[Problems to be solved by the device]

 However, knowing the approach of another ship only by such radar or visual observation is not a problem if the radar is always being looked at, but while the ship is doing other work and not seeing the radar, the ship suddenly sees When approaching, it may not be enough in time to know it later by radar. Moreover, especially in recent ships, the one-man system has been adopted, and it is physically impossible for a single operator to keep a constant eye on the radar, because one operator has to perform all the operations. In addition, under the current situation where only the radar is used for confirmation, it is not possible for the operator to ignore the anxiety that the surrounding conditions cannot be confirmed by “ear”.

The present invention has been made by paying attention to such problems of the prior art. In steering when the visibility of a ship is not good, such as night navigation or fog navigation, an external whistle sound of an external vessel is generated. By issuing a warning in the wheelhouse based on sound (for example, reproducing external sound in real time), the operator can be alerted through his or her hearing, etc., and ship operation can be made safer. It is an object of the present invention to provide an external acoustic warning device for a ship that can be used.
