1、花式喷泉是近年来随着控制系统的发展,出现的一种控制技术与花式观赏相结合的一种产物。随着可编程控制器在我国的迅速发展,对花式喷泉的控制要求也越来越高,使得越来越多的控制部分需要可编程控制器来实现。本文结合毕业设计任务书的要求,以花式喷泉为研究对象,采用了 S7.300系列PLC作为变频器的控制器,变频器再控制电机输出功率。对花式喷泉的控制系统的总体功能进行了分析,阐述了可编程控制器的组成和工作原理。提出了喷泉硬件的各组成模块及详细的硬件模块设计方案,并对控制方式进行了设计和程序的编写。本设计采用变频器作为水泵的控制器,改善了喷泉系统的控制品质,并真正地达到了节能和实时控制的要求。音乐喷泉是在可编
2、程控制器控制的基础上加入音乐控制系统,计算机通过对音频信号的识别,进行译码和编码,音频信号一般通过音响等设备传递给PLC控制中心,伴随着信号模数和数模的转换,对需要的信号进行处理,再将输出信号传送给变频器,从而控制喷泉的喷射效果,使喷泉造型、灯光的变化和音乐的情绪保持同步,使喷泉表演更加生动更加富有内涵及水的艺术。关键词:音乐喷泉;可编程控制器;变频器;转换器;控制系统AbstractAbstractFancy control technology and the emergence of a fancy watch combination of aproduct.
