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 ship display device comprising:

a position calculating module configured to acquire a positioning signal of a ship and to calculate a position of the ship;

a behavior calculating module configured to calculate a direction of the ship based on the positioning signal;

a position storage module configured to store a position in response to determining that the direction that has been calculated by the behavior calculating module changes by at least a predetermined angle within a predetermined period of time; and

a mark display processing module configured to display, in a display screen, a current travel mark at the position stored in the position storage module during a current travel of the ship, and a prior travel mark at a previously stored position, the previously stored position corresponding to the position stored in the position storage module during a previous travel of the ship prior to the current travel.

2. The ship display device of claim 1,

the position storage module being further configured to store a speed of the ship at the position;

and

the mark display processing module being configured to display the current travel mark in a different appearance according to the speed of the ship.

3. The ship display device of claim 1,

the position storage module being further configured to store a time associated with the position;

and

the mark display processing module being configured to display the current travel mark in a different appearance according to the stored time.

4. The ship display device of claim 1, the ship display device being configured to connect with a depth sounding module configured to detect a water depth;

and

the mark display processing module being configured to display the current travel mark in a different appearance according to the water depth detected at the stored time.

5. The ship display device of claim 1, wherein the ship display device is configured to prohibit storing of the position when a predetermined condition is satisfied.

6. The ship display device of claim 5, wherein the predetermined condition is satisfied when a previously stored ship position is within a prescribed range set based on the position of the ship.

7. The ship display device of claim 5, wherein the predetermined condition is satisfied when the ship is within a prescribed range set based on an inputted position set in advance, or when the inputted position set in advance is within a prescribed range set based on the position of the ship.

8. The ship display device of claim 5,

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

9. The ship display device of claim 5, wherein

the ship is a first ship;

the ship display device further comprises a communication device configured to connect with an identification information receiver for receiving identification information transmitted from a second ship; and

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

10. The ship display device of claim 1, the mark display processing module being configured to refrain from displaying the current travel mark on the display screen when a predetermined condition is satisfied.

11. The ship display device of claim 1, where a positioning change that satisfies a determination condition set includes a positioning change associated with a fish bite.
