The ultrasonic device of driving birds based on the infrared sensor

To reduce and avoid bird damage accidents, a driving-bird device with infrared sensors and ultrasonic generator is designed. Pulse infrared sensor induction principle is analyzed, and several factors, such as the distance and number of infrared transceiver, size and flight speed of the birds, which influences the sensing distanc are considered. The high frequency with low intensity ultrasonic bird driving system is introduced, and the ultrasonic transmission distance and sound intensity attenuation phenomenon are analyzed. The experimental results show that the proposed system has achieved good driving effect with the characteristics of simple hardware circuit, strong disturbance to the light, far emission distance and no environmental pollution.
