Abstract

This disclosure provides a moving body display device, which includes a position calculating module for acquiring a positioning signal of a target moving body and calculating a position of the moving body, a behavior calculating module for calculating a positional change of the moving body based on the positioning signal, and a position storage module for storing a position where the positional change is detected when the positional change that satisfies a determination condition set is detected.

Claims

1. A moving body display device, comprising:

a position calculating module for acquiring a positioning signal of a target moving body and calculating a position of the moving body;

a behavior calculating module for calculating a positional change of the moving body based on the positioning signal; and

a position storage module for storing a position where the positional change is detected when the positional change that satisfies a determination condition set is detected.

2. The moving body display device of claim 1, wherein the behavior calculating module calculates a speed or a direction;

and

wherein the position storage module stores, when it detects that the speed calculated by the behavior calculating module changes by a predetermined amount of change or more within a predetermined period of time, or when the direction calculated by the behavior calculating module changes by a predetermined angle or more within the predetermined period of time, a position where the change is occurred.

3. The moving body display device of claim 2, wherein at least one of the conditions of the predetermined period of time, the predetermined amount of change, and the predetermined angle is changed according to a speed of the moving body.

4. The moving body display device of any one of claims 1 to 3, further comprising a mark display processing module for displaying in a display screen a mark at a position where the positional change is occurred.

5. The moving body display device of claim 4, wherein the position storage module stores the position where the positional change is occurred and stores a speed of the moving body;

and

wherein the mark display processing module sets the mark of a different appearance according to the speed.

6. The moving body display device of claim 4, wherein the position storage module stores the position where the positional change is occurred and stores a time at which the position is stored;

and

wherein the mark display processing module displays the mark in a different appearance according to the time.

7. The moving body display device of claim 4, wherein the moving body display device is configured to connect with a depth sounding module for detecting a water depth;

and

wherein the mark display processing module displays the mark in a different appearance according to the water depth at the time of storing the position where the positional change is occurred.

8. The moving body display device of claim 1, wherein the moving body display device has a prohibiting function to prohibit storing of the position where the positional change is occurred when a predetermined condition is satisfied.

9. The moving body display device of claim 4, wherein the mark display processing module does not display the mark on the display screen when a predetermined condition is satisfied.

10. The moving body display device of claim 8, wherein the predetermined condition is satisfied when the position stored in the past where the positional change was occurred exists within a prescribed range set based on the position of the moving body.

11. The moving body display device of claim 8, wherein the predetermined condition is satisfied when the moving body exists within a prescribed range set based on an inputted position set in advance, or when the inputted position set in advance exists within a prescribed range set based on the position of the moving body.

12. The moving body display device of claim 8, wherein the moving body is a ship;

and

wherein the predetermined condition is satisfied when the ship exists within a prescribed range set based on a coastline, or when the coastline exists within a prescribed range set based on the position of the ship.

13. The moving body display device of claim 8, wherein the moving body is a first ship;

and

wherein the moving body display device is configured to connect with an identification information receiver for receiving identification information on a second ship; and

wherein the predetermined condition is satisfied when the second ship that transmitted the identification information exists within a prescribed range set based on the position of the first ship, or when the first ship exists within a prescribed range set based on the position of the second ship.
