Detailed Description
Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
Fig. 1 shows a distributed self-inspection bird repelling system for a substation according to a preferred embodiment of the present invention, which includes:

The central processing unit controls the bird repelling instruction to only have a single variable of ultrasonic frequency, and counts the number of bird activities under the condition of the single variable within a period of time to obtain the optimal bird repelling ultrasonic frequency. Specifically, a frequency is randomly generated at the initial working stage of the ultrasonic bird repelling device, the bird repelling instruction is kept unchanged within a set time, the set time can be one day or several days, so that differences caused by work and rest activities of birds in different time periods are eliminated, and the bird activity times under the ultrasonic frequency within the set time are counted. And in the next same set time, the central processing unit only changes the ultrasonic frequency in the bird repelling instruction of the same bird repelling unit, ensures that the working conditions of other bird repelling devices except the ultrasonic bird repelling device in the bird repelling unit and the working time of the ultrasonic wave sent each time are not changed, and counts the bird activity times under the changed ultrasonic frequency in the set time.
