Description

Technical Field [0001] The present invention relates to an intelligent fish-fighting apparatus and a fish-

The present invention relates to an apparatus and a method for eliminating fish by generating an evasive sound that a fish dislikes. More particularly, the present invention relates to an apparatus and method for automatically recognizing and recognizing the size of a fish species and a fish school, The present invention relates to an intelligent fish-fighting device and an intelligent fish-fighting method that can effectively prevent a fish from being introduced into a take-in part of a facility by automatically generating sound selectively.

In facilities such as power plants and factories, necessary water is taken from the sea or river. When the fish approach to the water intake part for taking the water, the intake part becomes clogged and it becomes difficult to take water. Which impedes the flow of water, thereby damaging the facilities and causing the fish to die.

Korean Patent Laid-Open Publication No. 2001-0001048 discloses a prior art in which a fish generates a disgusting signal in order to prevent a fish from approaching or entering the intake port of a nuclear power plant.

 The fish have different frequencies and sizes of acoustic signals (hereinafter referred to as "avoiding acoustic signals") that they dislike depending on their types. Therefore, in order to effectively eliminate the fish approaching from the fish to the protection point requiring protection such as the withdrawal sound signal by using the avoidance acoustic signal, it is necessary to grasp the type of the fish to approach and generate the avoidance acoustic signal having the frequency that the fish dislikes . If the acoustic signal is not the avoidance frequency of the frequency that the fish dislikes, the fish will continue to approach the withdrawal point despite the acoustic signal generation, and the effect of the fish is not exerted.

It is also important to control the size of the evasive acoustic signal in accordance with the number of fishes approaching the intake, that is, the size of the fishery, in order to effectively prevent fishes and to prevent unnecessary killing of fishes. Even if only a small number of fish are approaching, an excessively large avoiding acoustic signal causes problems such as the death of a fish rather than the eradication of fish. On the contrary, when a large number of fish are approaching, Avoiding loudness If only acoustic signals are generated, it is not possible to eradicate the fish approaching the intake.

However, only the vague concept of eliminating the fish by generating the evasive acoustic signal that the fish dislikes in the prior art that has hitherto been known has been disclosed, and only the evasive acoustic signal suitable for the fish species approaching the protection point of the intake port In addition to the concept of selective generation, the concept of controlling the volume of the evasive acoustic signal is not presented at all in consideration of the size of the fish group to be approached, and no specific means for implementing it is available .

The fish approach detection sensor 11 detects the movement of the fish by sensing the approach of the fish to the protection point. For example, the fish approach detection sensor 11 detects a movement of a fish by using a fish motion approach It can be used as the detection sensor 11. Since the motion sensor itself capable of recognizing the motion of the object is known, a detailed description thereof will be omitted. The fish image acquisition sensor 12 may be constituted by a photographing device such as an infrared camera. When it is recognized by the fish approach detection sensor 11 that the fish approaches the protection point, the fish image acquisition sensor 12 ) Acquires the image of the fish by photographing the approaching fish. The fish approach sensor 11 and the fish image acquisition sensor 12 may be implemented as a single device. The fishery scale detection sensor 13 is to acquire data on the size (scale) of the fishery to be approached when it is recognized by the fishery approach sensor 11 that the fish is approaching the protection point.

The fishery scale evaluation module 33 may also be implemented in the form of a program, i.e., software, running on a computer.

The sound source selection module 4 selects the avoidance acoustic signal that the fish species dislikes based on the fish species discriminated by the fish species classification module 3. [ Specifically, the sound source selection module 4 receives evaluation results of the fish species and the fish scale through the control module 2, and selects the avoidance acoustic signals. 4 shows a schematic configuration diagram of the sound source selection module 4. As shown in the figure, the sound source selection module 4 is provided with a sound source database 41 for the avoidance sound signal, And a sound source extraction module 42 for automatically extracting the avoidance acoustic signal corresponding to the species identified by the sound source database 41 from the sound source database 41.

First, the fish approach detection sensor 11 detects the movement of the fish and senses that the fish approaches the protection point (step S1-fish approach detection step). If it is recognized that the fish approaches the protection point, the approaching fish is acquired using the fish image acquisition sensor 12 (step S2-fish image acquisition step). At this time, a process of acquiring data on the size of a fishery group to be accessed using the fishery scale sensor 13 may be performed together.

After the fish image is acquired and data on the fish scale is acquired as needed, the fish image data of the fish is compared with the fish image stored in the fish image database 31 to find the fish species of the fish S3-species determination step). At this time, it is also possible to perform a process of evaluating the fish scale based on the fish scale data acquired by the fish scale sensor 13.

Subsequently, on the basis of the information on the fish species, the avoidance acoustic signal that the fish species dislikes is determined, and the sound source is extracted from the sound source database 41 (step S4-avoiding acoustic signal determination step). At this time, the size of the sound volume according to the fish scale can also be determined. In other words, it is also possible to carry out a step of determining the magnitude of the sound volume suitable for eradicating the fish group according to the size of the fish group.

When the sound source of the avoiding acoustic signal is extracted and the magnitude of the sound volume is also determined, the fish is allowed to react with the avoiding acoustic signal so that the avoiding acoustic signal is transmitted through the avoiding acoustic signal generator 5 (Step S5-avoiding acoustic signal generating step).

As described above, in the intelligent fish-fighting apparatus 100 according to the present invention and the intelligent fish-fighting method using the same, a fish which approaches the protection point by generating an evasive acoustic signal responds to such evasive acoustic signals, This is achieved by choosing a suitable acoustic signal suitable for the type of fish to be approached, that is, the fish species to be accessed, as much as possible. In other words, according to the present invention, the type of fish approaching the protection point is detected and the avoidance acoustic signal having a frequency disliked by the fish is generated. Accordingly, the fish avoids the avoidance acoustic signal, , Thereby effectively exterminating the fish approaching the protection point.

In particular, according to the present invention, it is possible to increase or decrease the magnitude of the evasive acoustic signal according to the size of the fishery. In this case, when a small number of fish approach, the evasive acoustic signal of a small volume is generated, It is possible to prevent excessive consumption of energy in the generation of the evasive acoustic signal, and conversely, when a large number of fish are approaching, a large volume of evasive acoustic signal is generated, It is possible to maximize the effect of eliminating the fish by exercising the eradication.
