[0054] As Figure 1 shown, it is an architecture diagram of an intelligent acoustic wave rainfall excitation system provided by an embodiment of this application. The intelligent acoustic wave rainfall excitation system includes: an air compression device 100, an acoustic wave generator 200, an intelligent control device 300, and an energy supply device 400, where:

[0055] The air compression device 100 is used to pressurize air and output the pressurized air through the gas outlet of the air compression device.

[0056] In this application, the air compression device 100 is used to compress air to a high-pressure state.

[0057] The following gives an example of the detailed structure of the air compression device 100. As Figure 2 shown, it is a schematic diagram of an implementation manner of the air compression device 100 provided by an embodiment of this application.

[0058] As Figure 2 shown, the air compression device 100 includes: an air compressor 101, a power mechanism, and a transmission mechanism. Among them, the power mechanism is connected to the transmission mechanism through a low-speed coupling 104, and the transmission mechanism is connected to the transmission shaft of the air compressor through a high-speed coupling 102.

[0059] The power mechanism includes a driving member 105 and a controller 106. The controller 106 is used to control the driving state of the driving member 105. Therefore, the rotation speed of the driving member 105 can be controlled through the controller 106, thereby adjusting the rotation speed of the air compressor. As an example, the driving member 105 can be a motor, an internal combustion engine, a ground gas turbine, an aviation turboshaft, or a turboprop engine. The controller 106 can adopt a frequency converter to adjust the rotation speed of the variable-frequency motor by adjusting the frequency of the frequency converter, thereby achieving the purpose of adjusting the rotation speed of the air compressor, and further adjusting the pressure ratio and gas flow rate of the air compressor. The driving member 105 can be fixed to the motor support through bolts, and the motor support can be fixed to the test platform through anchor bolts.

[0060] The transmission mechanism includes a speed increaser 103 and couplings. The couplings include a high-speed coupling 102 and a low-speed coupling 104. The input shaft of the speed increaser 103 is connected to the low-speed coupling 104, and the output shaft of the speed increaser 103 is connected to the transmission shaft of the air compressor through the high-speed coupling 102.

[0061] The power mechanism is connected to the input shaft of the speed increaser 103 of the transmission mechanism through the low-speed coupling 104, thereby driving the speed increaser 103 to rotate. The speed increaser 103 increases the rotational speed of the input shaft according to a certain transmission ratio through several internal gear transmissions, and outputs the increased rotational speed from the output shaft. The output shaft of the speed increaser 103 is connected to the transmission shaft of the air compressor through the high-speed coupling 102, so that the air compressor can be driven to rotate. By driving the transmission mechanism through the power mechanism to increase the rotational speed, the air compressor can be driven to rotate at a high speed, which plays a role in increasing the air flow pressure.

[0062] In addition, during the operation of the transmission mechanism, the gears in the speed increaser 103 need to be lubricated and cooled, and the bearings also need lubricating oil. Therefore, in the embodiment of the present application, a lubricating oil station is provided for the speed increaser 103 to provide lubricating oil for lubrication and cooling. The speed increaser 103 and the lubricating oil station of the speed increaser 103 are connected to the test platform through supports and bolts. If the lubricating oil grades and lubrication parameters of the lubricating oil stations of the air compressor and the speed increaser are the same or similar, the air compressor and the speed increaser can use the same lubricating oil station.

[0063] The above air compression device is composed of an air compressor, a power mechanism and a transmission mechanism. The power mechanism is connected to the transmission mechanism through the low-speed coupling 104, and the transmission mechanism is connected to the transmission shaft of the air compressor through the high-speed coupling 102. By driving the transmission mechanism through the power mechanism to increase the rotational speed, the air compressor can be driven to rotate at a high speed, which plays a role in increasing the air flow pressure. Thus, by adjusting the rotational speed, the flow rate and the air pressure ratio can be adjusted. The higher the rotational speed, the greater the gas flow rate and the higher the air pressure ratio. It can realize the real-time adjustment of the air pressure intensity, the gas flow rate and the air pressure ratio, improve the conversion efficiency of high-pressure air in the supercharging system, and meet the requirements for high-pressure gas in different specific scenarios. And the structure of the air compression device is reliable and has high stability. It can be applied to some scenarios with strict requirements on the volume of acoustic equipment, with a wide application range and strong mobility.

[0064] The structure of the air compressor will be described by way of example below.

[0065] As Figure 3 shown, it is a schematic diagram of a structure of the air compressor provided by the embodiment of the present application. The air compressor includes a rotor dynamic balance assembly 1, a bearing housing assembly 2, an intake cap 13, an intake valve assembly 3, a diffuser valve assembly 4 and an exhaust volute 5.

[0066] The bearing housing assembly 2 and the intake cap 13 are respectively located at both ends of the rotor dynamic balance assembly 1, and the intake valve assembly 3, the diffuser valve assembly 4 and the exhaust volute 5 are respectively connected and matched outside the rotor dynamic balance assembly 1.

[0067] The rotational motion of the rotor dynamic balance assembly 1 causes the intake valve assembly 3 to suck air from the atmosphere, and the rotor dynamic balance assembly 1 can do work on the air flow by means of the blades, and then the air flow enters the diffuser valve assembly 4. In the diffuser valve assembly 4, the air flow is decelerated and diffused, so that the velocity of the air flow can be converted into a static pressure rise, further increasing the gas pressure, and pressurized gas can be obtained. Finally, the pressurized gas can be collected by the exhaust volute 5 and discharged into the acoustic wave generator 200. The air compressor is supported by the exhaust volute and the volute base and is installed on the test platform.

[0068] In an alternative implementation, the air compressor further includes: an outer casing 6 and a centrifugal casing 7, wherein the outer casing 6 and the centrifugal casing 7 are arranged outside the rotor dynamic balance assembly 1. The intake valve assembly 3, the outer casing 6, the centrifugal casing 7, the diffuser valve assembly 4 and the exhaust volute 5 are arranged in sequence.

[0069] In an alternative implementation, the air compressor 100 further includes a guide basin 8 and an intake filter assembly 9. A guide basin 8 is arranged on the outer wall of the end of the rotor dynamic balance assembly 1 close to the intake cap 13, so that an intake passage is formed between the guide basin 8 and the intake valve assembly 3, and the intake filter assembly 9 is located at the intake port of the intake passage. Among them, the guide basin 8 is used for guiding, so as to improve the intake effect. The intake filter assembly 9 is used for filtering impurities in the air, preventing them from entering the air compressor along with the gas, and reducing other influencing factors.

[0070] The inlet of the acoustic wave generator 200 is connected to the gas outlet of the air compression device 100, and the acoustic wave generator 200 is used to generate acoustic wave beams.

[0071] The acoustic wave beams generated by the acoustic wave generator 200 can form an acoustic wave field that stimulates the condensation of water vapor in the clouds.

[0072] The intelligent control device 300 is respectively connected to the air compression device and the acoustic wave generator, and is used to control the air compression device and the acoustic wave generator to be in the working state if it is detected that the current environmental conditions meet the preset rainfall excitation conditions.

[0073] Exemplarily, if it is detected that the current environmental conditions do not meet the preset rainfall excitation conditions, the air compression device and the acoustic wave generator are controlled to be in the non-working state.

[0074] In the embodiments of the present application, the acoustic wave generator 200 and the air compression device 100 work together. The acoustic wave beams are disturbed and the air in the high-pressure state is ejected to promote the condensation of water vapor in the clouds into raindrops. The ejection of the air in the high-pressure state can significantly increase the speed and efficiency of water vapor condensation, and act together with the acoustic wave beams to enhance the rainfall excitation effect.

[0075] The energy supply device 400 is respectively connected to the air compression device 100, the acoustic wave generator 200 and the intelligent control device 300, and is used to supply energy to the air compression device, the acoustic wave generator and the intelligent control device.

[0076] An embodiment of the present application provides an intelligent acoustic wave rainfall excitation system. The acoustic wave rainfall excitation technology is a new physical rainfall method. The acoustic wave rainfall excitation technology does not use chemical agents and is environmentally friendly, meeting the requirements of sustainable development. Acoustic waves can quickly spread and act on a large area of clouds, and the effect of stimulating rainfall is significant and rapid. If the intelligent control device detects that the current environmental conditions meet the preset rainfall excitation conditions, it controls the air compression device and the acoustic wave generator to be in a working state. The air compression device in the working state is used to pressurize the air; the acoustic wave beam generated by the acoustic wave generator in the working state can form an acoustic wave field that stimulates the condensation of water vapor in the clouds. The acoustic wave generator and the air compression device work together, and the acoustic wave beam disturbs and the injection of high-pressure air promote the condensation of water vapor in the clouds into raindrops. The injection of high-pressure air can significantly increase the speed and efficiency of water vapor condensation, and act together with the acoustic wave beam to enhance the rainfall excitation effect.

[0077] The acoustic wave generator will be described below.

[0078] In an optional implementation manner, the acoustic wave generator includes: a high-frequency acoustic wave generator for generating high-frequency acoustic waves higher than or equal to a first frequency; a low-frequency acoustic wave generator for generating low-frequency acoustic waves lower than or equal to a second frequency, and the second frequency is lower than the first frequency; an acoustic wave director disposed at the air outlet of the acoustic wave generator for concentrating the high-frequency acoustic waves and the low-frequency acoustic waves to a target area to be rained.

[0079] Exemplarily, the range of the high-frequency acoustic waves can be from 10 kHz to 50 kHz, that is, the first frequency can be 10 kHz.

[0080] Exemplarily, the range of the low-frequency acoustic waves can be from 20 Hz to 200 Hz, that is, the second frequency can be 200 Hz.

[0081] Wherein, the high-frequency acoustic wave generator and the low-frequency acoustic wave generator are respectively connected to the intelligent control device 300.

[0082] The high-frequency acoustic waves and the low-frequency acoustic waves act together to generate an acoustic wave field that can stimulate the condensation of water vapor in the clouds. The high-frequency acoustic waves are used to disturb the water vapor molecules and stimulate the water vapor in the clouds by changing the frequency and amplitude. The low-frequency acoustic waves assist the high-frequency acoustic waves in water vapor condensation and increase the condensation effect.

[0083] Exemplarily, the acoustic wave director can be a horn-shaped director to improve the directivity and intensity of the acoustic wave beam.

[0084] Exemplarily, the target area can be the area where rainfall is needed. Exemplarily, the target area includes longitude and latitude.

[0085] The structure of the high-frequency acoustic wave generator will be described below. Exemplarily, the high-frequency acoustic wave generator includes, but is not limited to: a piezoelectric ceramic oscillator, an oscillation circuit, and an acoustic wave director. The oscillation circuit generates an electrical signal of a third frequency and transmits it to the piezoelectric ceramic oscillator through a wire. After receiving the electrical signal, the piezoelectric ceramic oscillator uses the piezoelectric effect to convert it into mechanical vibration and generate high-frequency acoustic waves. The acoustic wave director collects and focuses the high-frequency acoustic waves emitted by the piezoelectric ceramic oscillator, making them face the target area and increasing the penetration and effective coverage area of the acoustic waves.

[0086] The piezoelectric ceramic oscillator, as the core component, is used to convert electrical energy into high-frequency acoustic waves. The piezoelectric ceramic oscillator is composed of multiple independent units arranged in an array to increase the coverage range of the acoustic waves. Each oscillator is made of high-strength ceramic material and has high-frequency vibration characteristics. The oscillation circuit is used to provide a high-frequency electrical signal to drive the piezoelectric ceramic oscillator to work. The oscillation circuit includes an oscillator, an amplifier, and a filter to ensure a stable high-frequency output. The acoustic wave director is a horn-shaped tubular structure used to focus and guide the acoustic waves to propagate towards the target area. Exemplarily, the acoustic wave director is made of heat-resistant and corrosion-resistant materials, and an acoustic wave reflection structure is designed inside.

[0087] Exemplarily, the direction of the acoustic wave director can be adjusted by an electric servo motor or a stepper motor.

[0088] Exemplarily, the third frequency can be the same as the first frequency. Exemplarily, the third frequency can be different from the first frequency.

[0089] The structure of the low-frequency acoustic wave generator will be described below.

[0090] The low-frequency acoustic wave generator includes an electromagnetic oscillator, a low-frequency oscillation circuit, and an acoustic wave amplifier; among them, the electromagnetic oscillator is used to convert electrical energy into low-frequency acoustic waves and is usually composed of a coil and a magnet. The coil is made of heat-resistant material and can work under a strong magnetic field. The low-frequency oscillation circuit is used to generate an electrical signal of a fourth frequency, which is lower than the third frequency, to drive the electromagnetic oscillator. The low-frequency oscillation circuit includes a low-frequency oscillator, an amplifier, and a filter to ensure a stable output of the low-frequency acoustic waves. The acoustic wave amplifier is used to enhance the intensity of the low-frequency acoustic waves so that they can be more effectively propagated into the clouds. The acoustic wave amplifier is composed of high-power semiconductor devices and can provide high-power output.

[0091] Exemplarily, the fourth frequency may be the same as the second frequency. Exemplarily, the fourth frequency may be different from the second frequency.

[0092] Low-frequency acoustic waves assist high-frequency acoustic waves in water vapor condensation, which is a technology that utilizes the characteristics of acoustic waves to promote the condensation of water vapor into droplets. The low-frequency acoustic waves have a longer wavelength and stronger penetration ability, and can affect a large area of the air region. Through large-scale low-frequency vibrations, the low-frequency acoustic waves can disturb the water vapor molecules in the clouds and the air. By vibrating the low-frequency acoustic waves, the water vapor molecules in a large area of the air region are disturbed. This large-scale vibration can increase the kinetic energy of the water vapor molecules and the probability of their collision, making it easier for the water vapor molecules to come into contact and collide. The energy of the high-frequency acoustic waves is more concentrated and can provide a stronger local disturbance. The high-frequency acoustic waves provide a higher energy density in a local area, further enhancing the kinetic energy and collision intensity of the water vapor molecules, thereby promoting the initial formation of water droplets.

[0093] When the low-frequency acoustic waves and high-frequency acoustic waves propagate in the air, standing waves may be formed. The pressure changes in the standing wave nodes and abdominal regions can further promote the condensation of water vapor. The standing wave effect will cause local high-pressure regions and low-pressure regions to appear in the air. This pressure change helps the aggregation and growth of water droplets. The low-frequency acoustic waves can cause large pressure fluctuations in the air. These fluctuations cause the water vapor molecules to continuously move between the pressure peaks and valleys, thereby increasing the collision opportunities. The low-frequency acoustic waves provide more favorable conditions for the high-frequency acoustic waves. By increasing the contact frequency of the water vapor molecules, the promotion effect of the high-frequency acoustic waves on water droplet condensation is enhanced. Through the synergistic effect, the low-frequency acoustic waves and high-frequency acoustic waves jointly improve the efficiency of water vapor condensation in the air, making it easier to form water droplets, and thus increasing the possibility of rainfall.

[0094] The structure of the energy supply device 400 will be described below.

[0095] As Figure 4 shown, it is a schematic diagram of an implementation manner of the energy supply device provided by the embodiment of the present application. The energy supply device includes but is not limited to: a solar panel 401, a control device 402, and an energy storage device 403.

[0098] The solar panel 401 converts solar energy into electrical energy. The MPPT solar controller optimizes the energy utilization. The energy storage device 403 stores electrical energy to ensure that the intelligent acoustic rainfall excitation system can continue to be powered when there is no sunlight. Using the solar panel 401 for energy supply is energy-saving and environmentally friendly.

The monocrystalline silicon or polycrystalline silicon solar cell is a high-efficiency energy conversion component, covered under the protective glass and installed on a bracket with an adjustable angle. Therefore, the solar panel 401 can be driven by the bracket to be adjusted in real time according to the illumination angle.

As the maximum power point tracking controller, the MPPT solar controller realizes the maximum power output by monitoring and adjusting the working point in real time to improve the energy utilization rate of the solar panel 401.

[0113] The working principle of the intelligent control device 300 will be described below.

[0114] The current environmental conditions of the current environment are detected by the sensor 302, such as humidity, temperature, atmospheric pressure, wind speed, and wind direction, and the detected current environmental conditions are transmitted to the data processing device 303 in real time. The current environmental conditions are processed by the data processing device 303 to obtain a processed data signal, and then the processed data signal is transmitted to the main controller 301.

Exemplarily, the main controller 301 can achieve remote data transmission and receive control instructions through the wireless communication module 304.

[0120] The wireless communication module 304 can achieve remote data transmission and receive control instructions, the signal amplifier 305 is used to enhance the signal strength, and the antenna ensures long-distance stable transmission of the signal.

[0121] Exemplarily, the wireless communication module 304 is connected to the main controller 301 of the intelligent control device 300 through a data line. Exemplarily, the signal amplifier 305 is connected to the wireless communication module 304 through a coaxial cable.

[0122] Exemplarily, the wireless communication module 304 includes a LoRa module, a Wi-Fi module, and an antenna. Among them, the LoRa module, as a long-range and low-power wireless communication module, is used for data transmission. The LoRa (Long Range Radio) module has the characteristics of low power consumption and long transmission distance, and is suitable for remote monitoring.

The signal amplifier 305 includes high-power RF components and has the characteristics of high gain and low noise.

[0123] The process of the intelligent control device 300 monitoring whether the current environmental conditions meet the preset rainfall excitation conditions will be exemplified below.

[0124] Exemplarily, the preset rainfall excitation conditions include: preset humidity conditions, preset temperature conditions, preset air pressure conditions, and preset wind speed conditions. The current environmental conditions include: current environmental humidity, current environmental temperature, and current environmental air pressure.

[0125] Exemplarily, the preset humidity conditions include that the current environmental humidity is greater than or equal to the preset humidity threshold. It can be understood that a certain level of humidity, such as 60%-80%, is required to effectively promote the condensation of water droplets. Exemplarily, the preset humidity threshold is 75%.

[0126] Exemplarily, the preset temperature conditions include that the current environmental temperature belongs to the preset temperature range. Exemplarily, the preset temperature range can be between 0°C and 30°C. Because too low or too high temperatures may affect the formation of water droplets or the propagation of acoustic wave beams.

[0127] Exemplarily, the preset air pressure conditions include that the current environmental air pressure belongs to the preset air pressure range. Exemplarily, the preset air pressure range can be from 980 hPa to 1020 hPa.

[0128] Exemplarily, the preset wind speed conditions include that the current environmental wind speed is lower than or equal to the preset wind speed threshold. It can be understood that too high a wind speed will interfere with the acoustic wave beam and the air jet effect.

[0129] Exemplarily, the preset wind speed threshold can be 10 m / s.

[0130] Exemplarily, if the current environmental humidity is greater than or equal to the preset humidity threshold, and the current environmental temperature belongs to the preset temperature range, and the current environmental air pressure belongs to the preset air pressure range, and the current environmental wind speed is lower than or equal to the preset wind speed threshold, it is determined that the current environmental conditions meet the preset rainfall excitation conditions; otherwise, it is determined that the current environmental conditions do not meet the preset rainfall excitation conditions.

[0131] In an alternative implementation, before the air compression device and the acoustic wave generator work, it is necessary to prepare and check the entire intelligent acoustic wave rainfall excitation system to ensure that each device is in good condition.

[0132] Exemplarily, it is necessary to detect the power of the energy storage device 403 through the main controller 301 of the intelligent control device 300 to ensure that there is sufficient power to support subsequent operations. If the power is insufficient, the intelligent acoustic wave rainfall excitation device can be charged through the solar panel 401 until the power is sufficient.

[0133] Exemplarily, it is necessary to determine whether the sensor 302 is in a working state because the working sensor 302 can detect the current environmental conditions.

[0134] Exemplarily, the main controller 301 will detect whether the current environmental conditions meet the preset rainfall excitation conditions; if not, it will continue to obtain the current environmental conditions through the sensor 302; if so, it will activate the air compression device and the acoustic wave generator to be in a working state.

[0135] The acoustic wave generator 200 and the air compression device 100 work together to focus and direct the acoustic wave beam to the target area, and the water vapor in the cloud is excited to condense into raindrops by the disturbance of the acoustic wave beam and the injection of compressed air.

[0136] Specifically, the main controller 301 issues a control command to start the air compression device 100 and the acoustic wave generator 200. The piezoelectric ceramic oscillator of the high-frequency acoustic wave generating device generates high-frequency acoustic waves under the drive of the oscillation circuit, and the acoustic waves are focused and guided into the cloud through the acoustic wave director. The electromagnetic oscillator of the low-frequency acoustic wave generating device generates low-frequency acoustic waves under the drive of the low-frequency oscillation circuit, and the intensity of the acoustic waves is enhanced through the acoustic wave amplifier and transmitted into the cloud. Under the combined action of the high-frequency acoustic waves and the low-frequency acoustic waves, the water vapor molecules in the cloud are disturbed, making it easier for them to condense into water droplets.

[0137] It is understandable that the sensors in the intelligent acoustic wave rainfall excitation system continuously monitor the current environmental conditions, which may change over time. The main controller 301 compares in real time whether the current environmental conditions meet the preset rainfall excitation conditions. If not, it controls the air compression device and the acoustic wave generator to be in a non-operating state. Exemplarily, the main controller 301 controls the operating states of the air compression device 100 and the acoustic wave generator 200 according to the real-time analysis results, and dynamically adjusts parameters such as the frequency of the acoustic wave beam, the power of the acoustic wave beam, and the air injection intensity. For example, if it is found that the current environmental conditions change, the frequency and power of the acoustic wave beam output by the acoustic wave generator 200 can be adjusted, and / or the air injection intensity of the air compression device can be adjusted to ensure the effect of rainfall excitation.

[0138] Exemplarily, the main controller can obtain the distribution state of water vapor molecules based on the current environmental conditions, so as to determine the meteorological conditions and atmospheric stability in the target area, and thus can select appropriate acoustic wave parameters and air injection intensity.

[0139] Exemplarily, the acoustic wave parameters include but are not limited to: low-frequency acoustic wave parameters and high-frequency acoustic wave parameters. Among them, the low-frequency acoustic wave parameters include: low-frequency acoustic wave frequency, low-frequency acoustic wave amplitude, and low-frequency acoustic wave wavelength. Among them, the high-frequency acoustic wave parameters include: high-frequency acoustic wave frequency, high-frequency acoustic wave amplitude, and high-frequency acoustic wave wavelength.

[0140] The method for determining the low-frequency acoustic wave frequency includes: determining the low-frequency acoustic wave frequency of the low-frequency acoustic wave according to the current environmental humidity and the cloud thickness of the current environment in the target area.

[0141] For example, the low-frequency acoustic wave frequency is between 20 Hz and 200 Hz. In the case of high humidity and thick clouds, a lower frequency is selected to enhance the penetration and vibration effects.

[0142] Exemplarily, the corresponding relationship between the environmental humidity, the cloud thickness and the low-frequency acoustic wave frequency can be set, and the low-frequency acoustic wave frequency corresponding to the current environmental humidity and the cloud thickness of the current environment in the target area can be found from this corresponding relationship.

[0143] The method for determining the low-frequency acoustic wave amplitude includes: determining the low-frequency acoustic wave amplitude according to the current environmental pressure and the current environmental wind speed. Usually, a higher amplitude is set when the wind speed is low and the air pressure is normal to ensure a wide range of effects.

[0144] Exemplarily, the corresponding relationship between the environmental pressure and the environmental wind speed and the low-frequency acoustic wave amplitude can be set, and the low-frequency acoustic wave amplitude corresponding to the current environmental pressure and the current environmental wind speed can be found from this corresponding relationship.

[0145] The method for determining the wavelength of low-frequency sound waves includes: calculating the wavelength using the formula λ = c / f, where c is the speed of sound and f is the frequency of the low-frequency sound wave. Exemplarily, ensure that the wavelength of the low-frequency sound wave is long enough to cover the target area, usually between several meters and dozens of meters.

[0146] The method for determining the frequency of high-frequency sound waves includes: determining the frequency of high-frequency sound waves based on the current ambient humidity and the current ambient temperature.

[0147] Exemplarily, the frequency of high-frequency sound waves is usually between 10 kHz and 50 kHz. In the case of high water vapor density, i.e., high humidity and moderate temperature, a higher frequency is selected to increase the energy density and condensation effect.

[0148] Exemplarily, the corresponding relationship between ambient humidity, ambient temperature, and the frequency of high-frequency sound waves can be set, so that the frequency of high-frequency sound waves corresponding to the current ambient humidity and the current ambient temperature can be found from this corresponding relationship.

[0149] The method for determining the amplitude of high-frequency sound waves includes: determining the amplitude of high-frequency sound waves based on the current ambient temperature and the current ambient pressure. Usually, a higher amplitude is set when the temperature is moderate and the pressure is normal to ensure local sound pressure changes.

[0150] Exemplarily, the corresponding relationship between ambient temperature, ambient pressure, and the amplitude of high-frequency sound waves can be set, so that the amplitude of high-frequency sound waves corresponding to the current ambient temperature and the current ambient pressure can be found from this corresponding relationship.

[0151] The method for determining the wavelength of high-frequency sound waves includes: calculating the wavelength using the formula λ = c / f, where c is the speed of sound and f is the frequency of the high-frequency sound wave. Exemplarily, ensure that the wavelength is short enough to form an effective standing wave, usually between a few millimeters and a few centimeters.

[0152] Exemplarily, the acoustic wave parameters can be dynamically optimized through fuzzy logic control, PID (proportional-integral-derivative control) control, or other algorithms.

[0153] Exemplarily, the initial low-frequency sound wave parameters set initially are as follows: the low-frequency sound wave frequency is 100 Hz (medium frequency, suitable for environments with lower clouds and higher humidity), the low-frequency sound wave amplitude is 0.8 Pa (sufficient to cause significant air vibrations in a large range), and the low-frequency sound wave wavelength is 3.4 meters (calculated using the speed of sound 343 m / s).

[0154] Exemplarily, the initial high-frequency acoustic wave parameters set initially are as follows: the high-frequency acoustic wave frequency is 25 kHz (with a higher energy density in a high-humidity environment, suitable for condensation), the high-frequency acoustic wave amplitude is 0.4 Pa (the local sound pressure is sufficient to promote water vapor condensation), and the high-frequency acoustic wave wavelength is 13.7 mm.

[0155] Exemplarily, after the intelligent acoustic wave rainfall excitation system has excited rainfall, the relationship between the change in rainfall, the current environmental conditions, and the acoustic wave parameters can be obtained every preset duration, such as 10 minutes. Assuming that under the configuration of the initial low-frequency acoustic wave parameters and the initial high-frequency acoustic wave parameters, after 1 hour of excitation, the rainfall significantly increases to 5 mm. Analysis shows that under the 25 kHz high-frequency acoustic wave, the water droplet formation efficiency is significantly improved. If the current environmental conditions (such as the current environmental wind speed increases to 8 m / s), then the low-frequency acoustic wave frequency is adjusted to 150 Hz to enhance the penetration. The high-frequency acoustic wave frequency is fine-tuned to 30 kHz to adapt to the local temperature change (27°C). After adjusting the acoustic wave generator and the air compression device, the rainfall further increases to 7 mm.

[0156] Exemplarily, the wireless communication module 304 can transmit real-time data to the remote monitoring center, and technicians can monitor the working state of the acoustic wave rainfall excitation system through a remote terminal communicatively connected to the monitoring center. Control instructions can also be sent through the remote monitoring center for necessary adjustments and optimizations to improve the flexibility and operational convenience of the system.

[0157] Exemplarily, when the preset rainfall is reached or the current environmental conditions no longer meet the preset rainfall excitation conditions, the intelligent acoustic wave rainfall excitation system will automatically stop working and enter the standby state, waiting for the next start instruction.

[0158] Specifically, the main controller 301 determines whether the preset rainfall excitation conditions are met or whether the current environmental conditions have changed according to the real-time current environmental conditions detected by the sensor 302. If the preset rainfall excitation conditions are not met, or the preset rainfall amount has been reached, the main controller 301 issues a stop instruction, and the acoustic wave generator 200 and the air compression device 100 stop working. The intelligent acoustic wave rainfall excitation system enters the standby state, and the intelligent control device 300 continuously monitors the current environmental conditions, ready to start the next rainfall excitation operation at any time. The energy supply device 400 continues to charge the energy storage device 403 through the solar panel 401 to ensure that the intelligent acoustic wave rainfall excitation system always has sufficient power to support the next operation.

[0159] Exemplarily, the change in the current environmental conditions and the rainfall effect during the process of the intelligent acoustic wave rainfall excitation system exciting rainfall can be monitored in real time through the sensor 302.

The inlet end of the acoustic wave generator is cooperatively connected to the outlet of the air compression device, and an acoustic wave field for exciting the condensation of water vapor in the cloud is generated by the acoustic wave generator. The energy supply device is communicatively connected to the air compression device and the acoustic wave generator respectively, and provides driving energy for the air compression device and the acoustic wave generator through the energy supply device. The intelligent control device is communicatively connected to the air compression device and the acoustic wave generator respectively, and intelligently controls the working states of the air compression device and the acoustic wave generator. Combining the dual excitation methods of acoustic waves and air compression, the acoustic wave generator and the air compression device work together, and the condensation of water vapor in the cloud into raindrops is promoted through acoustic wave disturbance and the injection of compressed air.
