Hardware implementation of beam formed ultrasonic bird deterrent system

Abstract

Bird activities at the transmission line threatens the safety and stability of transmission lines which results in power disruption. Current available ultrasonic bird deterrent system is not effective in eliminating bird activity at transmission lines as the signals travel in omnidirectional. This results in waste of energy as the signal is transmitted to the places where the birds are absent. Hence, it creates a necessity in developing an improved ultrasonic method which utilizes beam forming method. This paper describes the hardware implementation of an ultrasonic bird deterrent system using beamforming method on transmission lines. This method is capable of focusing its wave on the birds and bird nests in a particular direction at the transmission lines where it creates discomfort to the birds and hence forcing the birds to evacuate the lines. © 2019 IEEE.
