Application of FGI FD100 low voltage frequency converter in music fountain

1. Overview

Chinese fountain is a vibrant art form with a long history. In recent years, because of the progress of science and technology, and the implementation of the reform and opening policy, the urban construction of our country has been rapidly developed, with the help of modern science and technology, fountain art has been unprecedented development.

Many fountains have been built in major, middle and small towns in China, especially hotels and tourist attractions.

Fountain waterscape art is an indispensable content. Because of its beautifying environment, beautifying landscape, creating atmosphere, attracting tourists, regulating microclimate and other effects, it is favored by the general public and becomes a good place for tourists to linger.

2. Implementation plans

The music fountain device converts the rhythm and intensity of the received music into a control signal, and then transmits it to the industrial controller, which separately controls each frequency converter through the bus.

On the PC, using the MODBUS Music fountain bus protocol, each PC is connected to dozens of frequency converters. The frequency converter uses the MODBUS protocol to control it so that its frequency changes and the pressure of the pump also changes. When the tone, rhythm and intensity of the music change, the pressure of the pump will also change, thus achieving better results.

3. Application advantages
