The Working Principle of The Musical Fountain

The working principle of the musical fountain:

1. Music signal processing

The control system of the musical fountain first needs to process the music signal and convert it into control instructions. This process usually includes the following steps:

Audio acquisition: through the audio input device (such as MP3 player, microphone, etc.) to collect music signals.
Signal analysis: Using Digital Signal Processing (DSP) technology, the music signal is analysed spectrally to extract audio information in different frequency bands.
Generate control commands: According to the results of audio analysis, generate the corresponding control commands for controlling the actions of water pumps, sprinkler heads and lighting systems.

2. Water pump and fountain nozzle control

Water pump system and nozzle system is the core of the music fountain, responsible for the formation of a variety of water effects. Control system according to the music signal spectrum analysis results, adjust the start and stop of the pump and nozzle spray angle, to achieve synchronous with the music rhythm of the water dance performance. For example, the low-frequency band music signal can control the large nozzle jet high water column, while the high-frequency band music signal can control the small nozzle jet fine water, forming a rich variety of water effects.

3. Lighting system control

The lighting system creates dynamic light and shadow effects by adjusting the colour and brightness of the lights to match the water flow and music. The control system uses PWM (Pulse Width Modulation) technology to adjust the colour and brightness of the LED lights in real time according to the changes in the music signal, so that the lighting effect fits perfectly with the water flow and music. For example, in the climax of the music, the lights can suddenly become brighter, creating a shocking visual effect.

4. Synchronised control

Synchronised control is the key to the musical fountain, to ensure that the water flow, lighting and music in the time of the exact same. Control system through the PLC (programmable logic controller) or special music fountain controller, real-time coordination of all parts of the work, to ensure smooth and coordinated water dance performance.
