本系统由欧姆龙CP1H型PLC作为控制核心,构建一个音乐喷泉控制系统。在CX-Programmer软件中对程序进行编译,并通过组态王软件将实时数据回传,从而实现对系统的监控。提出了一种新的方法来控制喷泉的变化,本设计将通过对音乐音频信号的实时采样,再通过变频器对潜水泵进行变频调速,利用各式喷头的喷射、摇摆、旋转来实现喷泉水柱高低、摇摆幅度、旋转速度来实时地展现音乐的频谱。
The system consists of Omron CP1H-type PLC as the control center to build a musical fountain control system. In the CX-Programmer software to compile the program, and through the Kingview software to real-time data back in order to achieve the monitoring of the system. This paper presents a new method to control the change of the fountain. This design realizes the fountain through the real-time sampling of the music audio signal, then the frequency conversion speed regulation of the submersible pump by the frequency converter, utilizing the spray, swing and rotation of various nozzles Water column height, swing amplitude, rotation speed to show the real-time music spectrum.
