摘要：为实现基于嵌入式ARM的音乐喷泉控制系统，采用三星公司以S3C2440微处理器为核心的架构，以Linux操作系统为平台，完成了音乐喷泉控制系统的软、硬件设计，并通过对音乐信号的预处理提取声音中的音量和音调，利用嵌入式系统有效地控制了音乐喷泉的喷水高度、灯光和水型变换。实验结果表明，该系统能实现全程实时音控，能自行识别乐曲旋律、节奏、乐感和音频强弱度，并有效地解决了传统音乐喷泉由于受到音乐特征的限制只能演奏几首曲目的问题。

Abstract: Aiming at realizing embeddedARM control system on musical fountain, the design of software and hardware of this system was completed by Linux operating system with the frame of SAMSUNGs S3C2440 microprocessor. After extracting the sounds volume and tonality by dealing with the music signal in advance, the musical fountains spraying height, light and shape of water were controlled efficiently by embedded system. The experiment results show that, this system could achieve real time voice operation, recognize musics cantus, rhythm, musicianship and the intensity of frequency by itself, and also solves the problem efficiently that the traditionalmusical fountain only can play several songs for the restriction of the musics character.
Key words: musical fountain; ARM; Linux; tonality recognition; Ethernet
