基于单片机的音乐喷泉控制系统的设计与制作.doc

摘 要 音乐喷泉作为自然景观和人文景观相结合的产物，已经深受广大民众喜爱。所以，有关音乐喷泉的研究也就丰富了起来。 目前,我国的大型音乐喷泉技术已日趋成熟,但对小型音乐喷泉的研究较少。控制系统是喷泉工程的关键部分,其余部分和普通类型的喷泉基本上一致。音乐喷泉的控制系统可采用可编程序控制器PLC作为控制核心，也可采用工控机作控制核心。但是对于小型音乐喷泉最适合的应是单片机作为控制核心。适合于一般城市小广场和普通住宅小区的小型音乐喷泉，由于其控制要求简单，使用单片机完全可以满足要求，而且因其成本低则更易于普及，是未来音乐喷泉的发展趋势。 本课题主要研究用单片机作为控制核心，设计出一种控制简单，成本较低且易于推广使用小型音乐喷泉的控制系统。系统原理：是用单片机根据音乐的强弱对电机，水泵或阀门进行控制，以便控制喷泉水柱的高低。输入为音乐成正比的电压信号，输出为对水泵转速或阀门的控制量。 期间本文还作出了硬件系统结构图，软件系统结构图以及部件连接和信号流程图等。 本系统由单片机，键盘，显示和输出驱动电路等组成。 关键词：AT89C51，74HC373，LED数码管...... Abstract The musical fountain takes the product which the natural landscape and the humanities landscape unify, was already deep the general populace is liked. Therefore, the related musical fountains research also enriched has come. At present, our countrys large-scale musical fountain technology already day by day mature, but are few to the small musical fountains research. The control system is the eruptive fountain project essential part, other part and the ordinary types eruptive fountain is basically consistent. Musical fountains control system may use programmable controller PLC to take the control core, may also pick employing labor to control machine makes the control core. But most suitable to be the monolithic integrated circuit takes the control core regarding the small musical fountain. Suits in the general urban small square and the ordinary residential district small musical fountain, because its control request is simple, uses the monolithic integrated circuit definitely to be possible to satisfy the request, because moreover its cost is low, then changes in the popularization, will be the future musical fountain trend of development. This topic main research takes the control core with the monolithic integrated circuit, designs one kind of control to be simple, the cost is low and easy to promote the use small musical fountain the control system. System principle: Is with the monolithic integrated circuit basis music strong and the weak
