Automatic fishing system and automatic fishing method

1. An automatic fishing system comprising:

a plurality of fishing machines each of which has rotation drums capable of winding fishing lines and capable of rotating in a reeling direction and an unreeling direction, a drive motor for driving said rotation drums in the reeling direction and the unreeling direction, and an electromagnetic clutch for transmitting rotation of said drive motor to said rotation drums;

a central control unit that is configured to communicate with each of the plurality of fishing machines;

a hooking detection means for detecting hooking of fish at any one of the plurality of fishing machines and for transmitting a fish hooking signal to the central control unit, when the central control unit receives the fish hooking signal, it sends a second signal to the other fishing machines that did not hook the fish; and

a fishing machine control means for controlling operations of the plurality of fishing machines in accordance with the second signal transmitted from said central control unit,

wherein said fishing machine control means is configured to control the drive motors of the plurality of fishing machines, when the second signal is received from the central control unit, to rotate the rotation drums of other fishing machines that hook no fish in the reeling direction, and

reeling direction so as to control hooks of said other fishing machines that hook no fish in the reeling direction by winding up the fishing lines with the hooks of said other fishing machines to a water surface or near the water surface when the other fishing machines receive the second signal.

2. The automatic fishing system as claimed in claim 1 , wherein each of the plurality of fishing machines comprises a rotation sensor means for detecting a rotational speed and a rotational direction of said rotation drums, and wherein said hooking detection means has an unreeled length calculation means for calculating, in accordance with the result of detection of said rotation sensor means, an unreeled length of the fishing line per unit time in case that said rotation drums rotate in the unreeling direction, and judges that a fish or fishes are hooked when the unreeled length of the fishing line per unit time calculated by said unreeled length calculation means becomes equal to or more than a predetermined length per unit time.

3. The automatic fishing system as claimed in claim 1 , wherein each of the plurality of fishing machines comprises a current detection means for detecting a current of said drive motor, and wherein said hooking detection means judges that, in accordance with the result of detection of said current detection means, a fish or fishes are hooked when the current of said drive motor detected by said current detection means becomes equal to or more than a predetermined value.

4. An automatic fishing method for controlling a plurality of fishing machines each of which has rotation drums capable of winding fishing lines and capable of rotating in a reeling direction and an unreeling direction, a drive motor for driving said rotation drums in the reeling direction and the unreeling direction, and an electromagnetic clutch for transmitting rotation of said drive motor to said rotation drums,

said method comprising:

a step of communicating with each of the plurality of fishing machines;

a step of detecting hooking of fish at any one of the plurality of fishing machines and for transmitting a fish hooking signal to a central control unit, when the fish hooking signal is received, it sends a second signal to the other fishing machines that did not hook the fish;

a step of controlling operations of the plurality of fishing machines in accordance with the second signal transmitted from said central control unit;

a step of controlling the drive motors of the plurality of fishing machines, when the second signal is received from the central control unit, to rotate the rotation drums of other fishing machines that hook no fish in the reeling direction; and

fishing machines that hook no fish in the reeling direction so as to control hooks of said other fishing machines that hook no fish in the reeling direction are to be wound up to a water surface or near the water surface when the other fishing machines receive the second signal.

5. The automatic fishing method as claimed in claim 4 , wherein said method further comprises a step of detecting a rotational speed and a rotational direction of said rotation drums, a step of calculating, in accordance with the detected rotational speed and the detected rotational direction of said rotation drums, an unreeled length of the fishing line per unit time in case that said rotation drums rotate in the unreeling direction, and a step of judging that a fish or fishes are hooked when the calculated unreeled length of the fishing line per unit time becomes equal to or more than a predetermined length per unit time.

6. The automatic fishing method as claimed in claim 4 , wherein said method further comprises a step of detecting a current of said drive motor in case that said rotations drum rotate in the reeling direction, and a step of judging that a fish or fishes are hooked when the detected current of said drive motor becomes equal to or more than a predetermined value.
