Damage caused by wild animals such as pheasants and magpies is a problem in rural areas. A bird repellent system based on sensing and repelling farm pest animals and birds is proposed herein. This system is equipped with a bird model part on a supporting platform and comprises a sound source generator, a system control user interface, and a sensor in the center. The sensor is composed of an illuminance sensor and a PIR sensor. The illuminance sensor distinguishes between day and night, whereas the PIR sensor detects birds or wild animals and outputs them from the sound generator. The entire system can be managed easily by the user interface and system control.

본 논문은 지향성 스피커를 이용한 유해조류 퇴치 시스템을 제안한다. 유해조류 퇴치를 위한 기존 사운드 시스템은 소음공해로 인한 문제와 단조로운 소리로 인하여 조류의 학습효과로 효과성이 저하되는 단점을 가진다. 본 논문에서는 지향성 스피커를 이용하여 주변의 소음을 최소화하고 스피커 구동 장치에 대해 상하 및 좌우 각도를 자유롭게 하여 활용성을 극대화하였다. 또한 다양한 스캐닝 패턴을 이용하여 학습효과로 인한 성능저하 문제를 해결하였다. 향후, 원격제어 기능과 조류 종류를 인식할 수 있는 딥러닝 모델을 적용하여 중앙통제가 가능한 플랫폼으로 발전시키고자 한다.

We improved the sound pressure of the speaker and allowed the speaker to rotate 360 degrees to improve the effectiveness of the acoustic type bird repellent system. The prototype of the bird repellent system was developed by evaluating sound pressure characteristics by distance and direction and installing orchards. As a result of the evaluation, the extermination sound pressure increased from a distance of about 30 m to a maximum of 60 m, and through the rotary speaker, the extermination distance could be widened in all directions without specific direction.

The epidemiological investigation of outbreak in korea confirmed that the inflow of avian influenza (AI) is related to the migration of migratory birds. In this study, avian repellents instrument were implemented and developed using the visual effects of lasers in accordance with the situation of small domestic fowl farms, and monitoring cameras were installed around each instrument to investigate the frequency of wild birds appearing and evaluate the performance of the instrument. Observation showed that the appreance ratio was reduced by 95%, and no significant reduction in the intrusion prevention effect by adaptation was observed on all fowl farms. In conclusion, it is expected that the outbreak of wild bird-borne infectious diseases such as avian influenza will be decreased if the device is installed on domestic fowl farms.
