Abstract: In summer, it is very happy to sit by the lake and watch a beautiful musical fountain. So while watching, have you ever thought about how the musical fountain is controlled? Or what are the characteristics of musical fountains? First of all, the music fountain programs the music through the program control system and the music control system, so that the fountain performs according to the rhythm of the music. Secondly, the characteristics of musical fountains include popularization, comprehensiveness, technology, etc. For specific knowledge about musical fountains, hurry up and read the article! 1. How to control the musical fountain

The musical fountain changes with the music, adding a beautiful visual and auditory feast to the people in the city at night. It is an important part of the fast-paced urban life at night. A very romantic and leisurely entertainment project. So how is the musical fountain controlled?

Music fountains program music through program control systems and music control systems, so that the fountain shape, music melody, and lighting are synchronously combined to produce ever-changing waterscapes that reflect the connotation and theme of music.

Use the physical waveform of the music file to divide it into several segments with an accuracy of ten milliseconds, and automatically identify the basic emotions of the music such as shock, yearning, lyricism, joy, excitement, sadness, joy, and enthusiasm. characteristics, converted into control signals, and after synchronization processing, output to the peripheral specific control unit through the signal output card, that is, according to the water type configuration rules, the actuators such as submersible pumps, solenoid valves, underwater lanterns and frequency converters are controlled, and the visual experience Integrate with the auditory experience.

When people experience various sounds, they will unconsciously connect these auditory sensations with the sensations of other non-auditory organs. This phenomenon is called synesthesia, which is a kind of heterogeneous and multi-unit synaesthesia. state corresponding phenomenon. Generally speaking, notes in the high range are often associated with bright visual feelings, positive or happy modal feelings, etc., while notes in the low range are often associated with dim visual feelings, depressed or sad modal feelings, etc.; soothing A rhythm can easily make people feel an open space or a calmer mood, while a rapid rhythm can easily make people feel a narrow space, agitated emotions, etc.
