[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1 like Figure 1-6 As shown, the shock and explosion expulsion device of rare earth special ceramic combined with cicada wing diaphragm includes a shell 1, the lower end of the shell 1 is connected to the base 4 through the upper and lower angle adjustment components and the horizontal angle adjustment components, and the middle part of the front end surface of the shell 1 is provided with a piezoelectric buzzing sound body 5, and the piezoelectric buzzing sound body 5 includes a buzzing tube 50, one end of the buzzing tube 50 is provided with a piezoelectric buzzing element 51, and the other end of the buzzing tube 50 is provided with a speaker channel 53, and a resonance cavity 52 is formed inside the buzzing tube 50.

The directional transmission of high-energy sound waves is achieved through the sound wave directional expulsion technology, so that the target can be dispersed at a farther distance. At the same time, due to the directional transmission of sound waves, the noise pollution to the environment is reduced. The sound wave directional dispersal technology can be used to drive birds in airports and farmlands, thereby solving the global problem that there is currently no effective bird-driving means.

[0030] The piezoelectric buzzer element 51 includes a piezoelectric ceramic laminate 511 and a diaphragm 512. The piezoelectric ceramic laminate 511 is located on the side of the diaphragm 512 away from the resonance cavity 52. ​​The piezoelectric ceramic laminate 511 is composed of a first double-sided copper electrode lead, a first piezoelectric ceramic sheet 5111, a middle copper electrode lead, a second piezoelectric ceramic sheet 5112, and a second double-sided copper electrode lead from top to bottom. Two piezoelectric ceramic sheets with the same polarity are glued together and connected in parallel under the action of an alternating electric field V. When one sheet is extended, the other sheet is shortened, thereby causing the ceramic sheets to generate bending vibration.

[0031] A plurality of piezoelectric buzzer elements 51 are provided, and the plurality of piezoelectric buzzer elements 51 are evenly distributed in a honeycomb shape.

[0032] The 360-degree image acquisition component 6 includes a camera seat 61, and eight camera seats 61 are arranged in a circular array and are evenly arranged on the side of the shell 1. A camera 62 is arranged in each camera seat 61, and the field of view of each camera is not less than 45 degrees. By setting a 360-degree image acquisition component and an image processing module, real-time acquisition of all-round image data can be achieved. Real-time image acquisition is performed through a multi-spectral camera, and bird features are identified and data is acquired. At the same time, the pixel-level geographic coordinate assignment submodule realizes the assignment of bird geographic coordinates, and provides coordinates for the directional expulsion of sound waves from the piezoelectric buzzing sounder.

[0033] The up-down angle adjustment assembly includes a U-shaped seat 21 and a base 22. The base 22 is located at the lower end of the housing 1. The left and right ends of the base 22 are connected to the upper two side surfaces of the U-shaped seat 21 through a rotating shaft and a bearing, respectively. A servo motor 23 for driving the rotating shaft to rotate is also provided on the outer surface of the U-shaped seat 21. The rotation of the servo motor can drive the rotating shaft and the base to rotate up and down at a certain angle.

[0034] The horizontal angle adjustment assembly includes a steering gear 3 , the lower end of which is horizontally arranged on the upper end surface of the base 4 , and the output end of the steering gear 3 is connected to the lower end of the U-shaped seat 21 .

[0035] The image processing module includes an image correction submodule, an image registration submodule, an image interpretation submodule and a pixel-level geographic coordinate assignment submodule.

[0036] The pixel-level geographic coordinate assignment submodule obtains the GPS coordinates of the center point of the image through the image POS data, and then analyzes the geographic coordinates of each corner point through the photographic geometry relationship, and then assigns geographic coordinates to each pixel of the image.

[0037] The image correction submodule includes multi-spectral camera spectrum calibration, image vignetting correction, and lens distortion correction.

[0038] The image registration submodule realizes information fusion between images through a registration algorithm.

[0039] The specific implementation of the image registration submodule includes the following steps: A, feature detection, automatically detects feature objects in the image, and represents the features through points, which are called control points; the feature objects include closed boundary areas, edges, contours, intersections, and corner points; B. Feature matching, establishes the correlation between the features of the scene image and the reference image, using multiple feature descriptors and similarity measures, together with the spatial correlation of the features; C, Transformation Model Estimation, which calculates the type and parameters of the so-called mapping function that aligns the sensed image and the reference image. The parameters of the mapping function are calculated by feature correlation; D. Image resampling and conversion, the sensed image is transformed using a mapping function, and the image values ​​of non-integer coordinates are calculated using interpolation techniques.

[0040] The image interpretation submodule recognizes the remote sensing image through a computer and finally realizes the remote sensing image understanding. The computer realizes the classification of the remote sensing image through a supervised classification or an unsupervised classification method.

[0041] Taking image acquisition, image correction, image registration and image interpretation as the technical route, the efficiency of image data processing and interpretation is improved by changing the original technical path and appropriately reducing the accuracy of image results.

[0042] The class D power amplifier module directly amplifies the modulated square wave signal processed by the DSP processor through an approximate square root algorithm.

[0043] Different from the traditional D-class power amplifier that generates a modulated square wave signal by comparing the input signal with a triangular wave or an oblique wave, the D-class power amplifier designed in the present invention does not use a comparator to perform PWM square wave conversion of the input signal, but directly amplifies the final modulated square wave signal, which is completed by the DSP inside the processor through an approximate square root algorithm or other algorithms. Relatively speaking, this modulation method can reduce signal distortion through algorithm optimization and distortion compensation, and can also perform signal equalization, special sound effects, frequency domain compensation and other processing during the processing process. However, the traditional D-class power amplifier uses hardware to complete signal modulation, which requires repeated debugging and improvement of hardware. It is difficult to achieve the same sound effect and low distortion, and the cost is also high. The modulated square wave signal output by the DSP is delayed by the dead time control circuit and then given to the full-bridge driver chip. The full-bridge driver chip controls the conduction and shutdown of the H-bridge circuit MOSFET tube to amplify the square wave signal, and the transducer array after matching the inductor filters the amplified square wave signal and performs electroacoustic conversion, and finally outputs the attack sound wave.

[0044] Example 2 like Figure 7-9As shown, on the basis of Example 1, an electromagnet 7 is arranged at the top of the shell 1, a sliding cavity 8 is opened in the shell below the electromagnet, a piston plate 9 which can slide longitudinally is sealed in the sliding cavity, a magnetic plate 10 is arranged on the upper end surface of the piston plate 9, and an alternating current is passed into the electromagnet during operation to generate an alternating magnetic field, which drives the magnetic plate and the piston plate 9 to reciprocate up and down through the magnetic force, a plurality of air inlet holes 11 are opened in the shell, and a one-way air inlet valve is respectively arranged in each of the air inlet holes, the air inlet holes are connected to the sliding cavity 8, and two air outlet pipes 12 which are connected to the outside are also arranged at the lower end of the sliding cavity 8, and one-way air outlet valves are respectively arranged in the air outlet pipes 12, and a plurality of ventilation holes 13 are opened on the left and right side walls of the shell.

[0045] When working, alternating current is simultaneously supplied to the electromagnet, causing the electromagnet to generate periodic alternating magnetic force, constantly attracting and repelling the magnetic plate, causing the magnetic plate to continuously reciprocate up and down, sucking the air inside the shell into the sliding cavity, and then spraying it out through the outlet pipe. At the same time, the outside air enters the shell through the ventilation holes, forming air flow, providing good heat dissipation inside the shell, and preventing its internal temperature from being too high.

[0046] A rainproof component is also provided in the shell 1, and the rainproof component includes a top plate 20, and a water-absorbing sponge 22 is provided at the upper end of the top plate 20, and the lower end of the top plate is connected to the upper end of the shell through a spring member 21, and the left and right ends of the lower end surface of the top plate are respectively provided with sealing plates 18 vertically downward, and the lower end of the sealing plate is provided with a magnetic plate 16 vertically downward, and the left and right ends inside the shell 1 are respectively provided with sealing grooves 15 vertically matched with the sealing plate 18 and the magnetic plate 16, the sealing plate 18 is provided with a second through hole 19 connected to the air outlet pipe 12, and the magnetic plate 16 is provided with a first through hole 17 connected to the ventilation hole 13.

[0047] The rainproof component also includes a pump air hole 23, which is connected to the slide cavity 8. The pump air hole 23 extends to the outside through a second air outlet pipe 25. A pressure relief valve 24 is provided at one end of the second air outlet pipe 25 close to the slide cavity. A corrugated water cooling pipe 26 is provided at the other end of the second air outlet pipe. The lower end of the corrugated water cooling pipe is connected to an air inlet pipe 27. The other end of the air inlet pipe 27 is connected to the lower end of the shell 1 through a reflux hole 28.

[0048] On rainy days, the absorbent sponge absorbs water, and the gravity increases, driving the sealing plate and the magnetic plate downward through the top plate to block the air outlet pipe and the air exchange hole 13. At this time, the pressure inside the sliding cavity increases until it increases to the critical value of the pressure relief valve 24. The pressure relief valve opens, and the gas inside the shell enters the corrugated water-cooling pipe through the pump air hole. The external rainwater contacts the corrugated water-cooling pipe to cool the gas inside the corrugated water-cooling pipe, and the cooled gas returns to the inside of the shell through the reflux hole 28, thereby cooling the inside of the shell with the help of rainwater on rainy days.

[0049] The lower surface of the piston plate 9 is fixedly connected with an electrostatic generator 14, and the outlet pipe 12 is arranged vertically downward at one end of the outer side. During ventilation, the electrostatic generator on the piston plate will generate negative charge and release it, so that the inhaled air has negative charge and is ejected through the outlet pipe, so that the dust in the outside world has negative charge and is subjected to the Lorentz force under the magnetic field of the magnetic plate 16, and is deflected in the direction away from the shell, effectively preventing the dust around the shell from entering the shell through the ventilation hole and damaging the internal components.

[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-mentioned embodiments only express the implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
