[0049] Figure 2 It is a dynamic spray control flow chart of the dynamic spray adjustment system. DETAILED DESCRIPTION

[0050] This application provides a dynamic spray adjustment system that addresses existing spray system technical issues, such as mis-spraying in unoccupied areas and spray failure in strong winds, resulting in low spray accuracy, poor environmental adaptability, and significant energy waste. By employing multi-sensor data fusion, real-time edge computing, and dynamic parameter adjustment, the system intelligently adapts to the environment, achieving precise spray control, significantly improving spray efficiency, and reducing resource consumption.

[0051] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0052] Example 1: Basic implementation of the dynamic spray adjustment system

[0053] like Figure 1 and 2 As shown, the implementation steps are:

[0054] System initialization:

[0055] Start the main control unit and initialize the human infrared sensor, millimeter wave radar sensor, and wind speed sensor.

[0056] Set the initial parameters of the spray actuator: nozzle angle 0°, droplet size 50 μm, and spray range 1 m.

[0057] Data collection and processing:

[0058] The human infrared sensor detects human activity signals in the target area in real time and outputs the signal strength value.

[0059] Millimeter-wave radar sensors monitor the speed and direction of human movement and identify the location of environmental obstacles.

[0060] The wind speed sensor collects the current environmental wind speed and direction data.

[0061] The edge computing module receives sensor data and performs real-time fusion calculations.

[0062] Dynamic adjustment of spray parameters:

[0063] Crowd density calculation: Map crowd density (low / medium / high) based on infrared signal strength.

[0064] Wind resistance adjustment: If the wind speed is greater than 3m / s, increase the droplet size to above 150μm. The droplet size adjustment device changes the particle size by adjusting the diaphragm pump pressure (0.5-2MPa).

[0065] Coverage range adjustment: When the crowd density is high, the solenoid valve group is controlled to expand the spray range to 5m, when it is low, it is reduced to 1m, and when it is medium, it is adjusted to 3m.

[0066] Nozzle Angle Adjustment: The adjustable nozzles are arranged in a ring. Based on millimeter-wave radar data, a stepper motor drives the nozzle deflection to point in the direction of the crowd (accuracy ±1°). The nozzle angle is achieved by a stepper motor drive, which is a conventional technology and will not be described in detail here.

[0067] Energy-saving control:

[0068] If no human activity is detected for 5 minutes, the system enters sleep mode (only the sensor maintains low power consumption).

[0069] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0070] The spray accuracy is improved to ≥90%, and ineffective spray is reduced by more than 50%.

[0071] Under strong wind conditions (force 8 wind), the droplet deposition rate remains above 85%, and the effective spray coverage rate can still be maintained at above 90%.

[0072] The response time is shortened to 0.3s, achieving millisecond-level real-time control.

[0073] The dynamic synchronization deviation between the spray direction and the pedestrian movement direction is achieved <5°, the spray range (1-5m) is adaptively adjusted with the density, and the water saving rate reaches 60%.

[0074] By adopting the technical means of energy-saving mode (sleep when no one is around), the technical problem of high energy consumption of traditional systems around the clock has been effectively solved, and the power consumption in the unmanned state has been reduced from 100W to 5W, with an energy saving rate of 95%.

[0075] Example 2: Implementation of AI prediction and multimodal interaction

[0076] This embodiment adds an AI prediction module on the basis of the first embodiment, wherein the implementation steps of the AI ​​prediction include:

[0077] AI prediction module deployment:

[0078] Upload historical temperature, humidity, and UV data to the cloud via Wi-Fi to train the LSTM model.

[0079] The model is deployed to the edge computing module to predict environmental changes in the next hour in real time.

[0080] Predictive spray trigger:

[0081] When the predicted temperature is >35℃, start spraying 10 minutes in advance to form a 0.5mm thick protective water film.

[0082] When the UV intensity is > level 5, the spray system is controlled to output 15℃ cool mist.

[0083] Multimodal interactive response:

[0084] When the millimeter-wave radar detects a pedestrian approaching (distance ≤ 1m):

[0085] The lighting system was switched to 4000K white light.

[0086] The spray system starts with low-intensity cold mist (coverage 1m).

[0087] The sound system plays the sound effect of running water (volume 30dB).

[0088] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0089] Surface thermal radiation is reduced by 20-25%, solving the problem of delayed cooling.

[0090] The adoption of millimeter-wave radar-triggered multimodal interaction (light-fog-sound linkage) technology effectively solves the technical problem of functional fragmentation in traditional equipment, and enables an immersive scene that automatically switches to "4000K white light + cool fog + light music" when pedestrians approach, increasing user satisfaction by 40%.

[0091] Example 3: Product implementation of smart garden lights

[0092] This embodiment provides a garden lamp with light pollution prevention and control and healthy lighting, including a lamp pole body and a multifunctional integrated module integrated with the lamp pole body. The multifunctional integrated module includes a lighting system, an acoustic system, and the dynamic spray adjustment system of the second embodiment.

[0093] Among them, the specific structure of the lamp pole body is as follows:

[0094] Material: Aluminum alloy hollow structure, waterproof grade IP66.

[0095] Dimensions: Height 3m, Diameter 150mm.

[0096] Multifunctional integrated module:

[0097] Lighting system:

[0098] Basic lighting: Batwing LED modules (120° diffusion angle) utilize a double-refraction technology with striped glass to increase illumination along the trail edge by 80% and reduce dark areas by 80%, providing a healthier and more comfortable lighting experience. Millimeter-wave radar monitors pedestrian flow and automatically reduces brightness to 10% when no one is around, saving over 60% energy and reducing light pollution.

[0099] Ambient lighting: Hidden RGBW light strip (color temperature 2700K-6500K adjustable). Improves light pollution prevention and control.

[0100] Spray system:

[0101] Nozzle: Annular distribution (spacing 30°), elevation angle 15°.

[0102] Pipeline: Built-in waterproof design, connected to high-pressure diaphragm pump.

[0103] Acoustic system: embedded speakers (frequency response range 100Hz-20kHz).

[0104] Light-fog-sound linkage: After the radar senses the movement of pedestrians, it triggers the switching of RGBW full-color light sources (such as warm light → blue healing light), changes in spray shape (such as increase or decrease in fog volume), and background music playback (such as the sound of flowing water).

[0105] Installation and commissioning:

[0106] Fix the light poles on both sides of the trail with a spacing of 10m.

[0107] After power on, the system performs self-test and sensor calibration (such as adjusting the radar ranging accuracy to ±0.5m).

[0108] Set the working mode (such as energy saving / full function mode) through the mobile phone APP.

[0109] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0110] The illumination at the edge of the trail has increased from 30lx to 90lx, and the dark area has been reduced by 80%.

[0111] By adopting the technical means of integrated lamp pole design (lighting + spray + audio + sensing), the maintenance complexity caused by the scattered installation of multiple devices has been effectively solved, thereby reducing the equipment volume by 40% and the installation cost by 30% compared with traditional solutions.
