Description

[0001] The present invention relates to a device for preventing intrusion of wild animals using a warning sound source,

The present invention relates to a device for preventing intrusion of wildlife using a warning sound source, and more particularly, to a device for preventing intrusion of a wild animal into a road or a track by radiating a high frequency warning sound source outside a human ' To a wildlife intrusion prevention apparatus using a warning sound source for a wildlife.

In general, the number of wild animals such as elk is rapidly increasing, which hinders the operation of trains. Hitherto, there have been hundreds of problems with the operation of (high speed) trains by animals (including birds).

In particular, mammals break down air hoses, lower panels, etc., and algae are in contact with catenary lines, causing a short-circuit failure.

For this purpose, a method of using a fence as a conventional device for preventing intrusion of wild animals has been used. The method of using such a fence physically prevents intrusion of wild animals, thereby preventing animals from moving to roads or tracks, .

However, in the case of the general line section, there are limitations in installation of facilities, and it is not easy to prepare a countermeasure, and there has been a problem that a fence or the like must be continuously installed in a place where animal intrusion is a concern.

In addition, the fence is subject to periodic inspection and maintenance costs as well as the initial installation cost, as well as the risk of shaking or breaking after being installed due to vibration and various impacts.

Therefore, in order to reduce the maintenance / repair cost, it is necessary to develop a new device which can not analyze the intrusion path of the animal and can not enter the track.

In order to solve the above-mentioned problems, there is provided an apparatus for preventing accidents caused by intrusion of wild animals and preventing wild animals from entering into wild animals by using a warning sound source capable of varying the output and frequency of sound sources according to the movement path of animals There is a purpose.

The present invention relates to a sound source generator for generating a sound source; A GPS module for generating current location information; A movement path DB for storing movement path data of a train; And a control unit for controlling the sound source output and the frequency of the sound generator by checking a movement path corresponding to the current position information in the movement path DB.

In one embodiment, the control unit includes: a sound source output variable module for controlling the output of the sound source to be variable; And a movement path module for confirming whether the frequent occurrence area of wild animals in the movement path DB overlaps with the current position generated in the GPS module and for transmitting an operation signal to the sound source output variable module when overlapped.

In one embodiment, the route path DB includes wildlife frequent occurrence area information or sound source output variable information.

In one embodiment, the control unit adjusts the frequency of the tone generator to be between 30 kHz and 100 kHz so as to exceed a human audible frequency.

In one embodiment, a directional speaker is connected to the tone generator.

According to the present invention, the maintenance / repair cost is reduced because it is mounted on a moving vehicle and the alarm sound is emitted to easily suppress intrusion of roads and lines of wild animals.

In addition, according to the present invention, it is possible to implement an environment-friendly wildlife intrusion prevention system that can replace wild fences by blocking wild animals moving at the same time and blocking animal moving paths at the same time.

FIG. 1 is a view showing the overall configuration of a wildlife intrusion prevention apparatus using a warning sound source according to an embodiment of the present invention.

For a better understanding of the present invention, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention may be modified into various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. The present embodiments are provided to enable those skilled in the art to more fully understand the present invention. Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that in the drawings, the same members are denoted by the same reference numerals. Further, detailed descriptions of well-known functions and configurations that may be unnecessarily obscured by the gist of the present invention are omitted.

The present invention utilizes the fact that the audio frequency band of an animal is much wider than that of a human being and has the function of shielding the entrance of a wild animal into a road or track by emitting a high frequency warning sound source outside the human's audio frequency band .

Table 1 below shows the audible frequency bands of humans and various animals.

These warning sources can be mounted on vehicles or installed on roads or railways. Since this warning sound source should not cause harmful environmental noise to humans / animals, it is necessary to turn off or attenuate the sound source output when the vehicle moves in a dense area such as a downtown area or a residential area, and in a region where wild animals such as mountainous areas are frequent, Is increased.

That is, the output of the warning sound source can be varied according to the moving path of the vehicle, thereby minimizing the environmental noise and effectively alerting the animal.

To this end, the present invention comprises a sound generator 40 for generating a sound source through a speaker 50, a GPS module 20 for generating current position information, a movement path DB 30 for storing movement path data of the train, And a control unit (10) for controlling the sound source output of the sound generator (40) and the frequency by checking the movement path corresponding to the current position information in the path DB (30).

The sound generator 40 generates a sound source having a frequency (30 kHz or more) outside the human audible frequency band according to an instruction from the control unit 10, adjusts the output, and is radiated through the speaker 50.

To this end, the control unit 10 is an essential device for varying the frequency and the output of a sound source according to the position where the vehicle passes. The control unit 10 includes a sound source output variable module 12 and a movement path module 14.

The sound source output variable module 12 is a module for controlling the output of the sound source to vary and controls the speaker 50 to generate a specific frequency through the sound source generator 40.

The movement route module 14 confirms whether the wild animal frequent occurrence area overlaps with the current position in the movement route DB, and transmits an operation signal to the sound output variable module when the overlap occurs, and the sound source generator 40 The frequency outside the frequency band is generated so that the appearance of the animal can be prevented in advance. Here, the current location is preferably generated by the GPS module 20, and wildlife frequent occurrence areas are stored in advance in a database or the like.

For example, according to an embodiment of the present invention, the controller 10 may adjust the frequency of the sound generator 40 to 30 kHz to 100 kHz so as to exceed the human audible frequency according to the operation signal, but is not limited thereto .

In addition, it is preferable that the movement path DB 30 includes wildlife frequent occurrence area information or sound source output variable information, and stores the variable source information of the sound source output according to the wild animal frequent occurrence area information as a specific numerical value.

Also, according to an embodiment of the present invention, a directional speaker may be connected to the sound generator 40 to generate the frequency of the sound generator 40 only in a specific direction, that is, a traveling direction of the vehicle.
