摘  要
         
隨著人們生活水平的提高和建立綠色城市的向往，音樂(lè)噴泉以其獨(dú)特的魅力和特殊的功能，愈來(lái)愈成為休閑娛樂(lè)產(chǎn)業(yè)中的一項(xiàng)重要產(chǎn)品,音樂(lè)噴泉的興建也越來(lái)越多。
根據(jù)目前音樂(lè)噴泉的發(fā)展現(xiàn)狀，完成了小型音樂(lè)噴泉系統(tǒng)硬件結(jié)構(gòu)設(shè)計(jì)和控制系統(tǒng)設(shè)計(jì)。控制系統(tǒng)的原理是利用8051單片機(jī)匯編音樂(lè)程序或者通過(guò)A/D對(duì)音頻信號(hào)進(jìn)行采樣和處理，分級(jí)控制單相電動(dòng)機(jī)，最終達(dá)到控制噴頭流量的方法。采用程序控制或人工按鍵控制電磁閥來(lái)控制花型。音頻信號(hào)還影響燈光色彩和燈光光線明暗的變化。從而使燈光色彩、燈光的閃爍和噴泉水姿隨音樂(lè)節(jié)奏而變化。

ABSTRACT                     
With the improvement of people's living standard and yearn for building green city, music fountain is more and more popular for its unique charm and special function large numbers of music fountain is increasingly built.
The hardware construction of small music fountain system and the design of controller system were completed according to the present situation of music fountain now. Its principle is that using the 8051 microcontroller to compilation Music program or to sample musical signals with A/D and doing its data and grade controlling single-phase electric motor, finally it implements the control of the flow out of nozzles. The flower shapes are controlled by program controlling or man-made keystroke controlling electromagnetic valves. The color、the light and shade of ray are changed by musical signals. So that the color、the light and shade of ray、the spring form is changed with music’s rhythm when music is played．
