摘要
音乐喷泉是近几年来出现的一种园林建筑与音乐欣赏相结合的产物。随着计算机软件硬件技术的飞速发展,新型喷泉与计算机的交互应用越来越广泛,音控喷泉也越来越复杂,越来越精密,使得越来越多的控制部分需要计算机来完成。因此,计算机控制音控喷泉成为必然趋势。但喷泉工程还存在一些技术难题,主要表现为明显的水声滞后效应。本文采用PWM变频调速、预处理、预测补偿控制和基于数据库的软件信号提前控制方法,提出了一种新的先进的音乐喷泉设计方案和控制途径,并与传统设计方案进行了分析比较,用面向对象的编程方法完成了对当今较为流行的MP3音频格式的解码,同时实时提取了音频信号。仿真分析证明该设计方案改善了传统控制方法的水声滞后效应,改善了喷泉系统的控制品质,,巩固学到的理论知识所开拓的视野,弥补课堂不足的目的,同时在实****过程中熟悉单片机的使用或者制作流程,为这次进行毕业设计搜集了所需的资料,增强了这次作业的责任心和对作业的严谨要求的态度。设计的内容主要是用单片机制作一个声控喷泉,对象为直流机控制的一个水泵。应能进行喷泉的喷水高度进行动态的设定,或按音量高低进行同步的变化。能更早的适应于社会。开发我们的创新能力。
关键字:变频调速、数据库系统、计算机控制、补偿控制。
Based on SCM music fountain design
ABSTRACT
Musical fountain there in recent years as a landscape architecture and music to enjoy a product of bination. With puter software of the rapid development of hardware technology, the new interactive fountain with puter more and more extensive applications, audio and control fountain also plex, more and more sophisticated, making more and more control over some of the needs of puter plete. Therefore, computer-controlled fountain sound control has e an inevitable trend. Fountain works but there are still some technical problems, mainly the water is clear hysteresis effect. In this paper,PWM frequency control pre-processing, forecasting pensation control signal based on the database software in advance of the control method, a new advanced design of the musical fountain and control means, and with the traditional designs are analyzed pared, using object-oriented programming methods for today's more popular MP3 audio format decoding, at the same time extract the audio signal in real time. Simulation analysis proves that the design of traditional control methods to improve the water hysteresis effect, the fountains to improve the quality control system in order to really achieve the requirements of
