Easy drive GT200 series frequency converter in the music fountain application

I. Introduction

Musical fountain is a computer-controlled sound, light and nozzle combination of different shapes, different colours, with the rhythm of the music and the composition of the integrated water features. Musical fountain water, light, colour and shape are beautiful. Often used as the theme of landscape garden. With the development of the national economy and people's living standards, people pay more and more attention to the improvement of the environment and beautification, musical fountains in the community, parks, leisure plaza has been widely used. Musical fountain control system is the core of the musical fountain design. Musical fountain control system mainly consists of audio control signal, frequency converter, water pump, multi-function valve, universal nozzle and water pipe. The fountain pump adopts frequency conversion speed control technology to achieve stepless speed control of the pump, according to the strength of the audio signal at any time to adjust the speed of the pump. Multi-function valve and universal nozzle by the fountain special controller control, according to the programme time limit of various patterns and shapes. We use the audio signal of the music to control the frequency converter, the audio model of the music itself is a very small power voltage signal, relatively speaking, the signal is very weak and then through the power amplification of the signal, can output 0-10V standard DC voltage signal, can achieve both the audio signal to the frequency converter control, both the pump wave control, so as to realise the music to the control of the fountain wave.
