BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighthouse information identification device, and more particularly, to a lighthouse information identification device incorporated in a navigation device such as a GPS navigation device mounted on a ship or the like.

[0002]

2. Description of the Related Art A navigation device used in navigation of a ship is a GPS navigation system that receives signals from a plurality of artificial satellites, specifies the position of the ship, and displays the wake of the ship together with a chart on a display screen. Although devices and the like are well known, among these types of navigation devices, there is generally a device configured so that various information can be obtained by moving a cursor on a display screen. In this type of navigation device used in ships, the position of a lighthouse is displayed on a chart displayed on a display screen. This is because the basics of ship navigation are to confirm the position of the lighthouse and to identify the lighthouse even at the present when this type of navigation device has become widespread.

[0003]

The above navigation apparatus has a problem that the lighthouse cannot be identified even though the position of the lighthouse can be confirmed on the chart. One way to solve this problem is to store the identification information of the lighthouse in a memory that stores the chart, and when any lighthouse is specified on the display screen, identify the lighthouse. There is a way to display information in text, and such devices already exist. However, the lighthouse is conventionally identified by the intermittent light or radio waves transmitted by the lighthouse itself, and there is a problem that it is difficult for a boat operator who is used to this to use it sensuously. In addition, in the case of displaying in characters, it is necessary to display in a language that can be read by a ship operator, and therefore, there is a problem in that a device capable of displaying several languages is required.

The present invention has been made in order to solve such a problem, and an object of the present invention is to provide a lighthouse information identification device capable of obtaining identification information based on an intermittent sound that has been conventionally used.

[0005]

SUMMARY OF THE INVENTION A lighthouse information identification device according to the present invention is a lighthouse information identification device in which a map indicating the position of a lighthouse is called up on a display screen. Alternatively, use the intermittent signal of radio waves, use the location of each lighthouse on the map as an address, and store the intermittent signal identifying each lighthouse as data, and specify one of the lighthouses on the display screen. Means for calling the intermittent signal data of the designated lighthouse, converting the data into an audible signal, and emitting sound.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram for explaining an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a processing unit constituted by a CPU, and 2 denotes a current position information from a positioning device (not shown) such as GPS or Loran. Is an input port for inputting cursor position information and control information for operating the apparatus, 4 is a chart memory, and 5 is a display unit. The current position information of the ship is input from the input port 2 by a positioning device such as GPS, Loran, etc., and a nautical chart near the current position is called from the nautical chart memory 4 and displayed on the display screen of the display device 5.
The ship's position and wake are displayed along with the chart. Up to this point, it is the same as the conventional navigation device. Reference numeral 10 denotes a part constituting the lighthouse information identification device of the present invention, 6 denotes lighthouse identification information formed of binary signal data of “1” and “0” to be called, and 7 denotes data of the binary signal. ON / OFF
Is a tone generator, and 8 is a speaker.

Further, the position of the lighthouse is described on a chart on the display screen, and cursor position movement information is input from the input port 3 by operating a mouse (not shown), and the cursor position on the display screen is displayed. Move to the lighthouse position on the chart and operate the mouse buttons. When the mouse button is operated, the identification information 6 of the lighthouse is called from the chart memory 4, and the intermittent sound for identifying the lighthouse is emitted via the tone generator 7 and the speaker 8. That is, at the position (address) of the lighthouse in the chart memory 4, the lighthouse identification information 6 for identifying the lighthouse is stored, for example, as a binary signal of "1" and "0", and the lighthouse is designated by the cursor. When,
The binary signal for identifying the lighthouse is converted into a power ON / OFF intermittent signal by the tone generator 7, converted into a sound by the speaker 8, and emitted as an intermittent sound.

Therefore, the boat operator can identify the lighthouse by listening to the same intermittent sound as the conventional intermittent sound due to the received radio wave or the intermittent sound at the same interval as the intermittent light, and can identify the lighthouse as if he / she is familiar with the conventional art. Identification can be performed. Also,
Since the identification information can be recognized by the intermittent tones common to all nations, it is possible to easily recognize even if the language used by the operator is different from the language displayed on the device.

Note that the processing unit 1 always knows the cursor position information, and emits an intermittent sound for identifying the lighthouse closest to the cursor position by adding strength to the difference in distance, ie, closest to the cursor. The intermittent sound of the lighthouse is emitted from the speaker 8, but when the distance is long, the sound may be weak, and the sound may increase as the cursor is approached. Further, instead of the sound emission by the intermittent sound, the display of the mark indicating the position of the lighthouse on the nautical chart may be displayed by intermittent light and dark or intermittent by color. Further, it is needless to say that the lighthouse identification information is not limited to the binary signal of “1” and “0”, but any other information may be used as long as the intermittent information at the same interval as the conventional intermittent transmission can be transmitted. Further, in the above embodiment, the navigation of the ship is described, but it is naturally conceivable to use it on other transportation means such as an aircraft.

[0010]

[Effect of the Invention] As described above, the lighthouse information identification device of the present invention can obtain the identification information of the lighthouse with the same intermittent sound as before, even if the lighthouse is specified on the map on the display screen. There is an effect that even a successful boat operator or foreigner can easily and intuitively grasp.
