Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in navigational aids in navigation aids.

From the 18th century to the present, navigational aid systems for ships at sea have been based on the visual sense of navigators throughout the night and night.

It is no exaggeration to say that ships rely on navigation aids using light waves, especially at night.

On the other hand, light wave or sound wave navigation aids mostly consist of independent devices and therefore have a limited amount of energy.

When using this limited amount of retained energy, there are ways to increase the effectiveness of the sign, such as focusing means using lenses to extend the range of light and make it more powerful, changing the color and quality of the light to increase the visibility effect, etc. Although all possible measures have been taken,
Not much consideration was given to how to use it rationally.

In other words, the light signals remained emitted in most cases even when the ship was not sailing, resulting in a large amount of wasted energy consumption.

The present invention limits the use of energy to a small output emission at all times, and when commanded by the navigator, releases a high output power for a predetermined short period of time, which is unimaginable for conventional light buoys, that is, an extremely large light power source. By using a system that works as a navigational beacon by turning on a light and returns to normal status once the demand command ceases, it achieves extremely efficient energy use and an extremely excellent beacon effect. The contents of the present invention will be explained in detail below with reference to the drawings.

Fig. 1 is a diagram showing the relative relationship between a sailing ship and a beacon according to an embodiment of the present invention, and Fig. 2 is a transmission and reception circuit diagram. It is.

Numeral 3 is a buoy with a high-output main light 4, a permanent light 5, and a fog horn 6 attached to the upper part, and a receiving part 7 at the lower part.
moored at 0.

The transmitter 2 provided on the ship 1 includes a command unit 11, a transmitter 12, and a transducer 13 as shown in the example in FIG. 2, and the receiver 7 provided on the buoy 3 includes a sensor 14, an amplifier 15, Power supply 16 via
Switching controller 17, lamp unit 18, main light 4 connected to
connected to.

The switching controller 17 is connected to the sunlight valve 2 via the lamp unit 19.
0 and the constant light 5 are connected.

In the above, the constant light 5 with a small output is always turned on by the lamp 19 in response to the operation of the sunlight valve 20,
It acts as a navigational aid for small ships that do not have a signal transmitter, and when it receives a command signal from a ship, the switching controller 1
7 is activated to open the lamp device 19, close the lamp device 18, and turn on the high-output main light 4 for a predetermined short time.

When the command signal is cut off, the switching controller 17 is restored, the lamp unit 18 is opened, the lamp unit 19 is closed, the main lamp 4 is turned off, and the regular lamp 5 is turned on, returning to the normal state.

In this example, the main light 4 and the permanent light 5 are configured in separate circuits, but a system may be adopted in which the main light 4 also serves as a permanent light and the light power can be adjusted in stages by voltage control based on commands.

Further, the main light 4 may be a high-output light that can be seen from a long distance.

If the fog horn 6 is connected in parallel to the circuit of the switching controller 17 (not shown) and the fog horn 6 is operated by changing the contents of the command signal, it can also be effective as a beacon during dense fog.

As the command signal, electromagnetic waves, light waves, sound waves, ultrasonic waves, etc. with relatively low power may be used.

As described above, according to the method of the present invention, energy that was always wasted in the conventional method is concentratedly released only when necessary, that is, for example, in a short period of time when a request command is issued from a navigating vessel approaching a strait or a port. By effectively operating the marker lights, energy consumption is extremely rational and economical.
Because it lights up for a short time, it can be used as a main light with a high output that was unimaginable with conventional light buoys, and the sign can be clearly distinguished from the harbor lights in the background, making it extremely easy to see. Furthermore, depending on the location, the response light quality, such as Morse code, can be used to further increase the recognition of the sign, which has an excellent feature that can further improve navigation safety.
