(Structure of aquatic organism induction system 10)
FIG. 3 is a diagram showing the configuration of the aquatic organism induction system 10 according to the first embodiment of the present invention. As shown in FIG. 3, the aquatic organism guidance system 10 includes a plurality of aquatic organism induction devices 100, a water tank 20, a power supply 140, a control device 150, a foot switch 160, and an indicator lamp 170.

The water tank 20 is configured to have an outer peripheral wall portion 22 and a bottom portion 24, and has a container shape with an upper opening. Water 40 and aquatic organisms 30 are housed in the aquarium 20. For the water tank 20, for example, a metal material (for example, stainless steel) is used. However, the present invention is not limited to this, and the water tank 20 may be made of other conductive material (for example, aluminum, copper, etc.), and other insulating material (for example, glass, FRP, etc.) is used. It may be a thing. Further, in the example shown in FIG. 3, the water tank 20 has an elliptical shape when viewed from above in a plan view, but the water tank 20 is not limited to this. For example, the water tank 20 may have a rectangular shape, a circular shape, another polygonal shape, or the like when viewed in a plan view from above.

The plurality of aquatic organism guidance devices 100 are installed along the inner peripheral surface of the outer peripheral wall portion 22 of the aquarium 20 in the vicinity of the inner peripheral surface. In the example shown in FIG. 3, a part of the inner peripheral surface of the outer peripheral wall portion 22 of the aquarium 20 so that a plurality of (14) aquatic organism induction devices 100 surround a predetermined part of the region 20A in the aquarium 20. It is installed over the range of. Not limited to this, the plurality of aquatic organism induction devices 100 may be installed over the entire inner peripheral surface of the outer peripheral wall portion 22 of the aquarium 20 so as to surround the entire area in the aquarium 20.

The power supply 140 supplies electric power (DC power) to the control device 150. In this embodiment, an AC power source (for example, a commercial power source) is used as the power source 140. Not limited to this, a DC power source (for example, a battery or the like) may be used as the power source 140.

The control device 150 is an example of "control means". The control device 150 is electrically connected to each electrode 104 of the plurality of aquatic organism induction devices 100 via the wiring 152. The control device 150 can apply electric power to each electrode 104 of the plurality of aquatic organism induction devices 100 by using the electric power supplied from the power source 140. For example, the control device 150 uses the AC-AC converter included in the control device 150 to output AC power of the first voltage (for example, 100V) supplied from the power supply 140 to a second voltage (for example, 30V). ) Convert to AC power. Then, the control device 150 applies an AC power of a second voltage to each electrode 104 of the plurality of aquatic organism induction devices 100.

The control device 150 classifies the plurality of aquatic organism induction devices 100 into a plurality of combinations, with the two aquatic organism induction devices 100 facing each other as one combination. Then, the control device 150 applies AC power having different voltage polarities to each combination of the one aquatic organism induction device 100 and the other aquatic organism induction device 100. For example, when the control device 150 applies an AC power of a positive polarity voltage to one aquatic organism induction device 100, the control device 150 applies an AC power of a negative polarity voltage to the other aquatic organism induction device 100. On the contrary, when the control device 150 applies the AC power of the negative polarity voltage to one aquatic organism induction device 100, the control device 150 applies the AC power of the positive polarity voltage to the other aquatic organism induction device 100. .. As a result, the control device 150 propagates electricity between one aquatic organism induction device 100 and the other aquatic organism induction device 100 in the water, whereby one aquatic organism induction device 100 and the other aquatic organism are aquatic. An electric field can be formed in the region between the bioinduction device 100 and the bioinduction device 100.

Here, the control device 150 applies electric power based on power setting values (for example, voltage, current, frequency, duty ratio, etc.) suitable for controlling a specific aquatic organism 30, to each of the plurality of aquatic organism induction devices 100. Can be applied to the electrode 104 of.

For example, the control device 150 can set a relatively small voltage value when the size of the aquatic organism 30 to be guided is relatively small. Further, for example, the control device 150 can set a relatively large voltage value when the size of the aquatic organism 30 to be guided is relatively large. Further, for example, the control device 150 can set a frequency and a duty ratio that are sensitive to the aquatic organism 30 to be guided.

In particular, the control device 150 is designed to set a voltage value (for example, 30 V or less) that does not cause the organism to die or be damaged while enabling the aquatic organism 30 to be electrically stimulated. Thereby, the aquatic organism guiding device 100 of the present embodiment can guide the aquatic organism in a predetermined direction by electrical stimulation in the aquarium 20 without killing and damaging the aquatic organism. Therefore, the aquatic organism induction device 100 of the present embodiment can induce aquatic organisms alive.

The control device 150 may be able to change the power setting (for example, voltage, current, frequency, duty ratio, etc.) of the power applied to each electrode 104 of the plurality of aquatic organism induction devices 100. In this case, the control device 150 can target a wider variety of aquatic organisms 30 by changing the power setting of the electric power applied to each electrode 104 according to the aquatic organism 30 to be guided. It will be possible. Further, in this case, the control device 150 has each electrode 104 so that the electric field strength becomes suitable according to various fluctuation factors of the electric field strength such as the size of the water tank 20 and the arrangement interval of the aquatic organism induction device 100. It is also possible to change the power setting of the power applied to.

Further, the control device 150 may be capable of selectively switching the aquatic organism guidance device 100 that applies electric power to the electrode 104 among the plurality of aquatic organism guidance devices 100. In this case, the control device 150 can change the region where the electric field is formed in the water tank 20 by selectively switching the aquatic organism induction device 100 that applies electric power to the electrode 104.

For example, the setting of the control device 150 may be changed by a changing means (for example, a DIP switch or the like) provided in the main body of the control device 150. Further, for example, the setting of the control device 150 may be changed from an external device (for example, a personal computer, a smartphone, a tablet terminal, etc.) that can be connected to the control device 150.

The AC power applied to each electrode 104 may be a rectangular wave or a sine wave. Further, the frequency of the AC power applied to each electrode 104 may change in time series with a predetermined frequency (for example, 1 KHz) as the center frequency. Thereby, the aquatic organism induction device 100 can induce various aquatic organisms 30 having various peak frequencies of sensitivity to electric power by the electric field formed by each electrode 104. In this case, the frequency of the AC power applied to each electrode 104 may be sequentially switched to a plurality of predetermined frequencies, or may be randomly switched.

The foot switch 160 is electrically connected to the control device 150. The foot switch 160 is an example of a “manual switch”, and the control device 150 switches on and off the power applied to each electrode 104 of the plurality of aquatic organism guidance devices 100. For example, when the foot switch 160 is not pressed, the control device 150 does not apply power to each of the electrodes 104 of the plurality of aquatic organism induction devices 100. On the other hand, when the foot switch 160 is pressed, the control device 150 applies electric power to each of the electrodes 104 of the plurality of aquatic organism induction devices 100.

The indicator lamp 170 lights up according to the operating state of the aquatic organism guidance system 10. For example, the indicator lamp 170 is configured to include a green lamp, a yellow lamp, and a red lamp. In this case, for example, when the power of the aquatic organism guidance system 10 is turned on and the electrode 104 of each of the plurality of aquatic organism induction devices 100 is not applied, the green lamp lights up. Further, for example, the indicator lamp 170 is a green lamp and a green lamp when the power of the aquatic organism guidance system 10 is turned on and is applied to each electrode 104 of the plurality of aquatic organism induction devices 100. The yellow lamp lights up. Further, for example, the indicator lamp 170 has a red lamp that lights up when the aquatic organism guidance system 10 is in a state of failure.

That is, each of the plurality of aquatic organism induction devices 100 is installed so that the second surface 102B of the case 102, which is covered with the electrode 104, faces the inner peripheral surface of the outer peripheral wall portion 22 of the aquarium 20. To.

As a result, even when a conductive material (for example, stainless steel) is used for the water tank 20, electricity propagated from the electrode 104 in each of the plurality of aquatic organism induction devices 100 is transmitted to the outer peripheral wall of the water tank 20. It is possible to prevent the transmission to the unit 22. Further, in each of the plurality of aquatic organism induction devices 100, the protective unit 105 provided on the first surface 102A provides external contact (contact with the aquatic organism 30, contact with the worker, etc.) to the electrode 104.

For example, when the number of aquatic organisms 30 staying in a predetermined part of the area 20A in the aquarium 20 is relatively small, the operator does not press the foot switch 160. Therefore, the control device 150 does not apply electric power to each of the electrodes 104 of the plurality of aquatic organism induction devices 100. Therefore, as shown in FIG. 5A, no electric field is formed in the region 20A, and the aquatic organism 30 can stay in the region 20A.

On the other hand, FIG. 5B shows a state in which electric power is applied to each electrode 104 of the plurality of aquatic organism induction devices 100.

Then, AC power having different voltage polarities is applied. As a result, as shown in FIG. 5 (b), a plurality of electric fields e (electric fields e for each combination of the aquatic organism induction device 100) are formed in the region 20A, and the aquatic organism 30 staying in the region 20A has an electric field. Upon receiving the electrical stimulation by e, the region 20A is retracted (that is, guided) to the outside.
