Problems solved by technology

However, the disadvantage of this technology is that the bird repellent device cannot distinguish what kind of birds are invading, and different birds are sensitive to sound waves. The sound waves that drive one bird may not be applicable to another bird. Therefore, the effect of repelling birds is not ideal
Chinese patent CN101422145B discloses an ultrasonic intelligent bird repelling device, but this device does not have the function of providing a targeted transmission frequency, and needs to continuously adjust the transmission frequency to realize bird repelling, so the bird repelling efficiency is not high

Embodiment 1

[0036] The present invention provides a bird repelling device based on bird feature recognition, such as Figure 1-2 As shown, a speaker 600 is installed on the pan / tilt 110, and the speaker 600 is provided with a radar 700, an infrared transmitter 800 and a camera 200. The pan / tilt 110 can rotate 360° in the horizontal angle range and 180° in the altitude angle range. , the horn 600 rotates with the pan / tilt 110, and the outgoing direction can be adjusted in all directions. At the same time, the horn 600, radar 700, infrared emitter 800 and camera 200 are oriented in the same direction, so that the working direction of each component is kept consistent, so that a high degree of coordination of each component is achieved and work efficiency is improved.

[0037] like figure 2 As shown, the recognition device 300 includes a feature extraction module 310 and a classifier 320 connected to each other, and the camera 200 is connected to the controller 100 through the feature extr...

Embodiment 2

[0044] A bird-repelling method based on bird feature recognition bird-repelling device, such as image 3 shown, including the following steps:

[0045] Step 1. When performing bird repelling work during the day, the radar 700 rotates with the pan / tilt 110 to scan and detect the surrounding space area. If a target bird is detected entering the detection area, the controller 100 controls the camera 200 to directly scan the target bird. Take a picture, and transmit the image information of the target bird to the identification device 300; when the bird repelling work is carried out at night, the controller 100 controls the infrared transmitter 800 to emit an infrared signal to the target bird, and after installing a filter on the camera 200 Carry out infrared imaging and photographing of the target bird, and transmit the image information of the target bird to the recognition device 300; Control the infrared transmitter and camera to work, and stop working at other times to redu...

Abstract

The invention discloses a bird repelling device based on bird feature recognition, which includes a cloud platform, on which a horn is installed, and a radar, an infrared transmitter and a camera are arranged on the horn; Bird genus information; signal selector, which outputs the peak frequency of the pain threshold curve of the target bird and the pain threshold sound pressure corresponding to the peak frequency according to the input bird genus information; the drive module, which passes a power The amplifier is connected to the speaker, and the driving module drives the speaker according to the peak frequency and the pain threshold sound pressure; and the controller is respectively connected to the identification device, the radar, the signal selector and the driving module in communication; wherein, the output sound frequency of the speaker and the peak frequency Equal, the sound pressure of the outgoing sound wave is not less than the pain threshold sound pressure. The invention provides targeted sound wave emission frequency and emission power by identifying birds, so that the bird repelling process is targeted, and the bird repelling effect is improved.

Description

technical field [0001] The present invention relates to a bird repelling device, more specifically, the present invention relates to a bird repelling method based on bird feature recognition. Background technique [0002] With the progress and development of human society, human beings' awareness of the protection of natural ecological environment has been continuously enhanced. Birds, as friends of human beings, have been listed as protection objects. For example, aircraft carriers, aircraft, power grids and other places clearly prohibit bird activities. Since birds cannot distinguish these local areas that will cause serious consequences to human activities, measures are usually taken to drive birds away on the premise of preventing damage to the lives of birds. out of these areas. [0003] At present, most of the devices on the market adopt high-intensity sound waves to drive away birds. However, the disadvantage of this technology is that the bird repellent device cann...
