AI Technical Summary

Technical Problem

Existing artificial rainfall devices lack real-time feedback and dynamic compensation capabilities during the simulation of natural rainfall, resulting in frequent fluctuations in rainfall intensity, an inability to achieve precise control, and phenomena such as over-dense or blind spots, which affect the simulation accuracy and system lifespan.

Method used

The system employs a rainfall intensity module, an initial control module, a feedback module, a water pressure fluctuation module, and a dynamic control module. By collecting rainfall intensity values ​​and hydraulic information from the spraying unit in real time, it generates adjustment strategies to achieve dynamic control of the water supply pipeline, eliminate unstable operation of the spraying unit, and precisely regulate water pressure and flow.

Benefits of technology

It achieves rapid and precise switching between spraying units, avoids system vibration, reduces energy consumption, has rapid response and adaptive capabilities, can converge to the target intensity in a short time, and features a modular design for flexible adjustment.
