毕业设计（论文）-单片机花样音乐喷泉设计.doc

摘要
进入了21世纪,随着人们生活水平的提高和建立绿色城市的向往,音乐喷泉以其独特的魅力和特殊的功能,愈来愈成为休闲娱乐产业中的一项重要产品,音乐喷泉的兴建也越来越多。根据目前音乐喷泉的发展现状,完成了小型音乐喷泉系统硬件结构设计和控制系统设计。控制系统的原理是利用单片机控制喷泉的功能,分级控制单相电动机,最终达到控制喷头流量的方法。采用程序控制或人工按键控制电磁阀来控制喷泉。音频信号还影响灯光色彩和灯光光线明暗的变化。从而使灯光色彩、灯光的闪烁和喷泉随音乐节奏而变化。
音乐喷泉是利用播放或现场演奏或按照预先编辑的程序变换喷水造型和灯光色彩强弱变化的喷泉。音乐喷泉控制系统可以使喷水造型变化和灯光的变化随音乐的节奏、旋律的起伏变化而变化,美妙动人;编辑程序一般可以随时修改,也可储存多种程序,随意调用。其原理是利用 89C51 单片机通过 A/D 对语音信号进行采样, 然后通过控制步进电机来控制电磁阀, 实现对喷头流量的控制, 从而使喷泉水姿、灯光色彩随音乐节奏而变化。

Has entered the 21st century, with the improvement of the people's living standard and establishing the yearning of the green city ,the fountain of the music es an important product in the recreation amusement industry. With its unique glamour and special function, construction of the fountain of the music is e more popular. According to the current situation of the development of the fountain of the music at present, finishing small-scale music fountain systematic hardware structural design and control system to design. The principle of the control system is to utilize the one-puter to control the function of the fountain, controls the single-phase motor in grades, reach and control the flow method of the shower nozzle finally. Controlling or artificial button controls the ic valve to control the fountain to adopt the procedure. Audio frequency signal still influences light color and light and shade change of light .Thus make the light color, light glimmer and fountain water appearance change with music rhythm.
Music fountain to utilize, broadcast or play live or vary, spray water model and the intersection of light and the intersection of color and the intersection of power and fountain of change according to procedure that edit in advance. Music the intersection of fountain and control system can make, spray water the model is changed and the change of the light varies with rhythm of the music, wave of melody, wonderful and moving; The editor can generally revise procedure at any ti
