The West Lake Music Fountain time is 19:00 and 20:00 every day, with 2 performances. The length of the West Lake Music Fountain is about 126 meters, and the width of the arc part is about 2 meters. There are seven main types of nozzles in the entire musical fountain, including two-dimensional nozzles, fountain nozzles, high nozzles, secondary nozzles, rainbow nozzles, air explosion nozzles, and pneumatic water film nozzles. The fountain lights use underwater LED lights that can change into several different colors. After careful design, the fountain nozzle can rotate 360 ??degrees and, in conjunction with music, can spray various shapes of water columns, water mist, and water balls. The music used in the fountain mainly includes West Lake characteristic songs, Chinese classical music and pop music, foreign classical music and pop music, etc. Scale of West Lake Musical Fountain: The West Lake Musical Fountain was built in 2003 during the West Lake Comprehensive Protection Project. There are nearly 400 nozzles, 224 of which can rotate 360 ??degrees to create more than 600 water shapes. The large nozzle in the middle can spray the water column to a height of more than 60 meters. Music fountain is a music control system based on program-controlled fountain. The computer decodes and encodes the audio and MIDI signals, and finally outputs them to the control system, so that the changes in the fountain and lights are synchronized with the music, thereby achieving the perfect combination of the fountain water shape, lighting, color changes and the musical conception, making the fountain performance more vivid Makes sense. When playing music, the new music arranged in the computer is processed by software to form different pulse signals, and the water pump is controlled by the frequency converter to eject water columns of different heights and sizes; the water column then passes through the rotating nozzle, forming different transformations of swaying or unrestrained; as the The music, it feels like the fountain is dancing.
