Problems solved by technology

The invention with the patent number CN106718386A only provides an observation method for bird damage in orchards, but does not provide corresponding solutions
And the patent No. is CN202773895U utility model patent numerical control optical bird damage prevention and control equipment, though can propose a kind of measure of intelligent solution bird damage, application environment is limited, and cost is too high, it is difficult to universal application; However, it cannot effectively judge the position of the bird and the distance from the fruit forest.
[0004] In the prior art, there is a lack of a device that can effectively recognize the sound of birds, discriminate and drive away birds within the range of fruit forests, and a method for realizing bird positioning

Embodiment 1

[0090] The present invention is realized through the following technical solutions, as Figure 1-Figure 5 As shown, a kind of intelligent fruit forest bird pest control equipment comprises a control module, a microphone array module, a loudspeaker, a wireless network module and a terminal connected with the wireless network module; connect.

[0091] It should be noted that through the above improvements, the microphone array module transmits the collected sound source signal to the control module, and the control module processes and analyzes the sound source signal, and transmits it to the terminal through the wireless network module. drive away.

[0092] The output end of the speaker is electrically connected with the audio decoder. The loudspeaker plays the corresponding audio output from the audio decoder, which is used to drive the birds away.

[0093] Other parts of this embodiment are the same as those of the foregoing embodiments, so details are not repeated here. ...

Embodiment 2

[0095] This embodiment is further optimized on the basis of the above embodiments, such as Figure 1-Figure 5 As shown, further, in order to better realize the present invention, it also includes a V3S processor connected to the control module, and the speaker and the wireless network module are respectively connected to the control module through the V3S processor.

[0096] It should be noted that, through the above improvements, the V3S processor controls network connection and sends and receives data, and queries node information through communication between devices for device feedback.

[0097] V3S processor and FPGA module are connected by SPI.

[0098] Other parts of this embodiment are the same as those of the foregoing embodiments, so details are not repeated here.

Embodiment 3

[0100] This embodiment is further optimized on the basis of the above embodiments, such as Figure 1-Figure 5 As shown, further, in order to better realize the present invention, a strobe light connected with the V3S processor is also included.

[0101] The strobe light adopts LED light-emitting diodes, the strobe light is externally connected to a 3.3V power supply, and the V3S processor can directly control its PWM wave to change the flickering form of the strobe light, thereby realizing driving.

[0102] Further, in order to better realize the present invention, the control module includes an FPGA module and a storage module connected to the FPGA module; the V3S processor and the microphone array module are respectively connected to the FPGA module.

[0103] It should be noted that, through the above improvements, the strobe light is electrically connected to the V3S processor. The strobe light adopts LED light-emitting diodes, which has high efficiency and low power consu...

Abstract

The invention discloses an intelligent fruit-bearing forest bird control device. The intelligent fruit-bearing forest bird control device comprises a control module, a microphone array module, a loudspeaker, a wireless network module and a terminal, wherein the terminal is connected with the wirelss network module; the microphone array module, the loudspeaker and the wireless network module are connected with the control module. The positioning method comprises the following specific steps that the control module collects a signal, and then the signal is filtered and denoised through a filter,so that the resolution of the signals is improved; by using the short-time Fourier transform time-frequency analysis technology, sound source information is extracted and identified. The intelligentfruit-bearing forest bird control device has the advantages that in a large-range environment, an orchard is supervised in real time through cooperative interaction of information between devices, thevoice of birds passing through a fruit-bearing forest can be identified, the birds within the fruit-bearing forest range are expelled in real time, and meanwhile, early warning is provided for a user.

Description

technical field [0001] The invention relates to the technical field of fruit forest prevention and control, in particular to an intelligent fruit forest bird pest prevention device and a bird positioning method thereof. Background technique [0002] The development of agriculture has always been the top priority of ensuring people's livelihood, especially the development of high-quality agricultural products to improve agricultural production efficiency. In fruit production, the harm of birds to fruit forests is increasing. The main reason is that with the promulgation of relevant laws and regulations on bird protection, people's awareness of bird protection has been continuously enhanced, and the number of bird species and populations has increased sharply; secondly, the number of pests on farmland and trees has been effectively controlled by pesticides, and birds Third, there are more and more types of fruit trees and larger planting areas, which provide fresh food source...
