DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fish signal detecting device for notifying a fisherman of a fish signal when a predetermined target fish is hooked on a hook.

[0002]

2. Description of the Related Art Generally, in the hands of a fisherman holding a former pole,
In addition to the vibration caused by the fish signal of the target fish, the vibration caused by the swing of the rod during the operation of the fishing rod, or the vibration generated from the natural environment such as water, waves, wind, and stones is combined and transmitted simultaneously. For this reason, considerable skill is required to sense only the vibration of the target fish due to the fish signal, and an amateur often loses the timing of matching with the fish message and misses the fish.

Therefore, conventionally, for example, Japanese Utility Model Application Laid-Open No. 62-94.
As disclosed in Japanese Patent Application Publication No. 780, an acceleration sensor is provided at the tip of the tip to detect vibration, a signal from the acceleration sensor is amplified, and a vibration generating member provided on the grip portion of the fishing rod is vibrated. Fishing rods have been developed in which a fish signal is sensed by vibration of a generating member. In such a fishing rod, even if the fish signal is small, the vibration generating member provided on the grip portion of the fishing rod vibrates sufficiently, so that the fish signal can be detected relatively easily.

[0004]

However, in such a fishing rod, vibration other than the vibration due to the fish signal is amplified simultaneously with the vibration due to the fish signal, so that it is difficult to reliably sense only the fish signal. There was a problem that is. The present inventor has conducted intensive studies to solve such a conventional problem, and as a result, if the type of fish is the same, the frequency of vibration generated in a fishing rod or a fishing line at the time of fish communication is substantially the same, and this frequency is And found that there is a specific dominant frequency depending on the type of fish and the type of fish.

[0005] That is, as shown in FIG.
When an acceleration sensor 13 is attached to 1 and the frequency of the fishing rod body 11 is measured when there is a fish signal, for example, in the case of a sweet fish, as shown in FIG.
The frequency measured by the acceleration sensor 13 is 10 Hz or less.
Becomes

The value of the dominant frequency 15 slightly varies depending on the size of the fish 17, the environment, and the like, but is substantially uniform depending on the type of the fish 17. For example, in the case of sweetfish, it is about 20 Hz.
It has been confirmed by the above-described experiments that the frequency is about 30 Hz for a fly and about 15 Hz for a carp, and is within the range of 10 to 40 Hz. The present invention has been made on the basis of such knowledge, and has as its object to provide a fish signal detecting device that can surely notify a fisherman of a fish signal of a predetermined target fish.

[0007]

A fish signal detecting device according to the present invention comprises a frequency detecting sensor for detecting the frequency of a fishing rod or a fishing line, and a frequency detected by the frequency detecting sensor. Is the dominant frequency of the target fish
It has a judging means for outputting a fish signal when it is within a predetermined frequency range nearby, and a notifying means for inputting the fish signal and notifying an angler that a target fish has been caught.

[0008]

In the fish signal detecting device of the present invention, when a fish hooks a fishhook, a fishing line and a fishing rod vibrate, and this vibration is detected by a frequency detection sensor, and the detected frequency is input to the determination means. Then, a preset type of target fish is
When hung, the fishing line and rods become dominant frequencies specific to the target fish
In order to vibrate , the frequency detected by the frequency detection sensor becomes a value within a set frequency range stored in advance in the determination means, a fish signal signal is output from the determination means to the notification means, by the notification means, The angler is notified that the target fish has been caught.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of a fish signal detecting device according to the present invention. In the figure, reference numeral 21 denotes a frequency detection sensor including, for example, an acceleration sensor. In this embodiment, the frequency detection sensor 21 is disposed in front of the grip 25 of the fishing rod 23 as shown in FIG.
The frequency of the is detected.

In FIGS. 1 and 2, reference numeral 27 denotes a judging means composed of, for example, a microcomputer. The judging means 27 inputs the frequency detected by the frequency detecting sensor 21 and outputs the frequency. Is within the predominant frequency of the fish signal of the target fish 29 and a predetermined set frequency range in the vicinity thereof. That is,
The determination means 27 stores the predominant frequency of the fish signal of the target fish 29 to be caught and a predetermined set frequency range in the vicinity thereof.

For example, when the target fish 29 is a sweet, as described above, since the dominant frequency of the sweet is about 20 Hz, 17 to 23 Hz is stored as the set frequency range. In FIGS. 1 and 2, reference numeral 31 denotes a notifying unit formed of, for example, a buzzer.
Inputs a fish signal to notify the angler 33 that the target fish 29 has been caught.

Hereinafter, the operation of the fish signal detecting apparatus will be described with reference to the flowchart shown in FIG. That is, when the fish hooks on the hook, the fishing line 35 and the fishing rod 23 vibrate, and the vibration is detected by the frequency detection sensor 21, and the detected frequency is input to the determining means 27 (step 1). Thus, it is determined whether the detected frequency is within the set frequency range (step 2).

When a target fish (for example, sweetfish) 29 of a preset type is hooked on the hook, the fishing line 35 and the fishing rod 23 are shifted to the predominant frequency (20 in the case of sweetfish).
(Around Hz), the frequency detected by the frequency detection sensor 21 becomes a value within a set frequency range (17 to 23 Hz for sweetfish) stored in advance in the judging means 27, and The fish signal is output to the notifying means 31 (step 3), the notifying means 31 operates, the buzzer sounds, and the angler 33 is notified that the target fish 29 has been caught.

In the fish signal detecting device configured as described above, the device includes a frequency detecting sensor 21 for detecting the frequency of the fishing rod 23, and a frequency detected by the frequency detecting sensor 21. Determining means 27 for inputting and outputting a fish signal when the frequency is within the predominant frequency of the fish signal of the target fish 29 and a predetermined set frequency range in the vicinity thereof;
The notification means 31 for inputting a fish signal and notifying the angler that the target fish 29 has been caught is provided.
It is possible to reliably notify the fisherman of the 9 fish signals.

In the embodiment described above, the target fish 29
Although, for example, an example in which the type is limited to one type such as sweetfish has been described, the present invention is not limited to such an example. 27-33Hz for 30Hz
Set frequency range, 1 for the prevailing frequency of Ayu 20Hz
Set frequency range of 7 to 23Hz, Carp dominant frequency 15H
A set frequency range of 11 to 17 Hz for z is stored, and, for example, in the case of a carp, a set frequency range of 11 to 17 Hz is selected according to the type of target fish to be caught, and the set frequency range is determined. By setting the frequency range of the means, it is possible to easily apply the present invention to a plurality of types of target fish.

Further, by making it possible to freely rewrite the set frequency range from the external input unit, it becomes possible to apply the set frequency range to more target fishes. Furthermore, in the above-described embodiment, an example in which the notification unit 31 is formed by a buzzer has been described. However, the present invention is not limited to this embodiment. For example, the notification may be performed by blinking a lamp. Of course, the gripping portion may be vibrated and notified, or of course, digitally displayed.

In the embodiment described above, an example in which the frequency detection sensor 21 is disposed on the fishing rod 23 has been described. However, the present invention is not limited to this embodiment.
For example, it goes without saying that a frequency detection sensor may be arranged on the fishing line 35.
