Embodiment

[0037] Such as figure 1 For the embodiment of the selection method of a kind of DQN-based ultrasonic repelling bird optimum frequency of the present invention, comprise the steps:

[0038] S1: Initialize the weight θ of the Q neural network of the bird protection device, the threshold of the number of iterations, prior knowledge, experience pool and number of iterations;

[0039] S2: Update the weight θ of the Q neural network;

[0040] S3: Use Doppler radar to detect and read the state of the bird within the detection range s t ;

[0041] S4: State s for the birdt Make a judgment, if the bird stays within the detection range, continue to step S5, if the bird does not stay within the detection range, repeat steps S3-S4;

[0042] S5: Judging whether there is prior knowledge of bird repelling in this area, including the more effective frequency of ultrasonic bird repelling in this area; if yes, then combine the prior knowledge to select the frequency with the largest Q value;...

Abstract

The present invention relates to the technical field of ultrasonic bird repelling, in particular to a DQN-based method for selecting the optimal frequency of ultrasonic bird repelling, which specifically includes the following steps: S1: Initialize the weight θ of the Q network of the bird protection device, the iteration threshold, Prior knowledge, experience pool and number of iterations; among them, the prior knowledge is based on the experience of bird damage protection in a certain area, including the birds with the most serious bird damage in a certain area and their most sensitive frequency range; S2: update Q The weight of the neural network θ; S3: use Doppler radar for detection, and read the state s of the bird within the detection range t ;S4: the state s of the bird t Make a judgment, if the bird stays within the detection range, continue to step S5, if the bird does not stay within the detection range, repeat steps S3-S4 and so on. The present invention overcomes the existing problems of single bird repelling frequency, randomly occurring ineffective bird repelling frequency, adaptation of bird repelling frequency by birds, and inability to drive away harmful birds in a targeted manner.

Description

technical field [0001] The invention relates to the technical field of ultrasonic bird repelling, in particular to a method for selecting the optimal frequency of ultrasonic bird repelling based on DQN. Background technique [0002] With the development of social production and people's living standards, power grid users have gradually increased their requirements for power supply quality and stability. In recent years, the transformation and upgrading of power equipment has greatly improved the quality of power supply, and the reliability and stability of power supply have been guaranteed. However, accidents of power outage and tripping also happen occasionally, which have a certain impact on life and production. Bird activity is one of the main causes of transmission line failures. [0003] Since the habits of the bird species involved in the transmission line are not considered, the frequency parameters of the bird repellent are designed in a generalized manner. Among ...
