音乐喷泉工程是一种集美感和音乐于一体的一种现代的广场景观和休闲娱乐设施，从最原始的单纯喷泉发展成为现在的音乐喷泉，再到后来的电影喷泉，它走过了一个不断发展的路程，在今天变得更加美观和新潮。今天将带给大家一个音乐喷泉产生的原理和喷泉工程中怎样设计高水平的音乐信号处理系统。

Music fountain project is a collection of beauty and music in the integration of a modern square landscape and recreational facilities, developed from the original pure fountain become now the music fountain, fountain to the later films, it has come a growing way, today has become more beautiful and fashionable today will bring you a music fountain of principle and how to design a high level of music fountain engineering signal processing system

音乐喷泉工程的原理是怎么样的呢？：简单得来说其实就是将音频信号转换成电频信号电频信号通过变频器控制水泵使水泵的压力随音乐的节奏的变化。根据播放的音乐来控制水柱，达到与音乐同步的效果。

How does the music fountain project work? : to put it simply is to convert audio signal into electrical frequency signal electrical frequency signal through inverter control water pump so that the pressure of the water pump with the change of the rhythm of the music according to the music to control the water column, to achieve the effect of synchronization with the music

喷泉的水柱是由水泵来控制的，而水泵是由三相异步电动机组成的，三相异步电动机的转速如果通入工频电源，转速是不变化的，变频器是专门针对电机调速的装置。由变频器控制电机的转速，使水柱发生变化。改变频率就改变了电机的转速，也就改变了水泵的压力，音乐的不同频率经单片机处理送到变频电机的控制端，使电机转速随音乐的音调，节奏，和强弱变化，水泵的压力随之变化，喷岀的水就有了高低变化。而且是由几套设备对多组喷嘴实施控制喷泉的形成是水泵。将音乐的节奏和强度转变为控制信号，此信号再控制一个电压控制器件，电源经过这个电压控制器件后，输出电压也随音乐的变化而改变，然后控制水泵电机。

Fountain of the water column is controlled by the water, and water pump is composed of three phase asynchronous motor, three-phase asynchronous motor speed if the power supply, power frequency speed is not changing, frequency converter is designed for motor speed control device is controlled by a frequency converter speed, the water column change change frequency to change the speed of the motor, also changed the pump pressure, music of different frequency by single-chip microcomputer to the control end of the frequency conversion motor, the motor speed with the tones of music, rhythm, and the strength change, pump pressure changes, spray water has a high and low change file Moreover, several sets of equipment control multiple sets of nozzles. The formation of the fountain is that the water pump transforms the rhythm and intensity of music into a control signal, which then controls a voltage control device. After the power supply passes through the voltage control device, the output voltage also changes with the change of music, and then controls the pump motor

怎样设计高水平的音乐信号处理系统呢？音乐喷泉工程是通过千变万化的喷泉造型，结合五颜六色的彩光照明，来反映音乐的内涵及音乐的主题，一座好的音乐喷泉，水形的变化应该能够充分地表现乐曲。是在程序控制喷泉的基础上加入了音乐控制系统，计算机通过对音频及MIDI 信号的识别，进行译码和编码，最终将信号输出到控制系统，使喷泉的造型及灯光的变化与音乐保持同步，从而达到喷泉水型、灯光及色彩的变化与音乐情绪的完美结合，使喷泉表演更加生动更加富有内涵及体现水的艺术。音乐喷泉：可以根据音乐的高低起伏变化。用户可以在编辑界面编写自己喜爱的音乐程序。播放系统可以实现音乐、水、灯光气氛统一，播放同步。

How to design a high level music signal processing system? Music fountain project is ruled by fountain modelling, in combination with colourful colour light illumination, to reflect the connotation of music and music theme, a good music fountain, changes in water to form should be able to fully reflect the music is on the basis of program control fountain joined the music control system, computer based on audio and MIDI signal identification, decoding and encoding of the final output signals to the control system, make the modelling of the fountain and the change of light and music, so as to achieve the fountain water type The change of light and color and the perfect combination of music emotion, the fountain show more vivid and more rich connotation and reflect the art music fountain of water: can vary according to the ups and downs of the music users can write their favorite music program broadcast in the edit interface system can realize music light atmosphere water, broadcast synchronization

简

集中分散式控制系统

本喷泉由主控机直接控制，主控机具有如下特征：

1．音乐信号采集功能，按频率特征抽取有效成分。

2．对喷泉设备进行故障诊断，可以对主机运行状态、漏电及驱动柜工作状态进行诊断。

3．中文菜单式操作系统，使操作者能够在短时间内学会操作，具有音乐喷泉的各种动态造型和花样变化显示功能，使操作人员通过计算机屏幕就能观察到喷泉的各种变化，极大地方便了音乐喷泉的配曲和操作人员使用。

4．开放式结构，人机界面友好，通讯接口及编程技巧对用户开放，只需通过鼠标的两个键即可完成音乐喷泉的配曲，这样就容易使音乐喷泉配曲库不断丰富，总给人耳目一新的感觉。

The fountain is directly controlled by the main control machine, which has the following characteristics: 1. Music signal acquisition function, according to the frequency feature extracting effective components (2) the fountain equipment fault diagnosis, can run on the host state working condition diagnosis 3. Leakage and drive ark type operating system with the Chinese menu, make the operator can learn in a short time, has a music fountain of various dynamic modelling and pattern change display function, make the operation personnel through the computer screen can be observed the changes of the fountain, bringing great music fountain cake-cutting and operating personnel 4. Open structure, friendly human-machine interface, communication interface and programming skills are open to users, only through the two keys of the mouse can complete music fountain music library, so it is easy to make music fountain music library constantly rich, always give a new and refreshing feeling
