Application of small nano-laser electronic fence combined with ultrasonic bird repellent device to monitor bird damage on power transmission lines

In order to improve the effect of bird damage monitoring on transmission lines, a bird damage monitoring technology for transmission lines based on small nano-laser electronic fences combined with ultrasonic bird repelling devices was studied. Determine the maximum monitoring range of laser signal monitoring of small nano-laser electronic fence; demodulate and preprocess the laser monitoring signal; determine the location of bird damage based on the laser signal, and monitor the cross- border bird damage; The frequency of the sound waves corresponding to the stay and flight of the flock realizes the ultrasonic vibration monitoring of the bird damage on the transmission line. The experimental results show that the researched bird damage monitoring technology reduces the false alarm rate and missed alarm rate, improves the recall rate of bird damage monitoring, effectively reduces the frequency of transmission line faults, and also increases the range of bird repelling, effectively improving the transmission line. Bird damage monitoring effect.
