基于STC89C52单片机音乐喷泉控制的设计

本文从系统方案、芯片选择、硬件电路搭建原理和软件设计原理等方面介绍了音乐喷泉的设计过程。通过A／D转换芯片对音频信号进行采样和处理，系统分级控制单相电动机，最终达到控制喷头流量的目的。还加以彩灯控制模块，实现音频信号对灯光的控制。实现在播放不同的音乐时，灯光色彩和喷泉水姿随音乐的节奏而变化。最后设计出一个采用单片杌作为以STC89C52单片机为主控制器的小型音乐喷泉控制系统。

The Design of Music Fountain Based on STC89C52 Single Chip

Abstract]In this paper, the design process of music fountain is introduced from the system program, chip select, hardware circuit structures principle and software design principles.The system hierarchical controls monophase machines by sampling and processing the audio signal through A/ D conversion chip, in order to control the nozzle flowing. The design also adds a control module of leds which can be regulated by the audio signal. The flowing and lighting can change with the rhythm of music. Finally, a control system as small musical fountain controller based on stc89c52 is designd.
