1.Overview

As a dynamic art landscape, fountain has a long history in China. In recent years, with the development of science and technology and the implementation of reform and opening up, urban construction has developed rapidly, and the art of fountain has also achieved unprecedented development with the help of modern science and technology. Large and medium-sized cities and even some small towns across the country have built a lot of fountain projects, especially hotels and tourist attractions. The art of fountain waterscape has almost become an indispensable content. They not only beautify the environment, embellish scenery, foil the role of the atmosphere and attract customers, adjust the microclimate and other functions play a very good role, so widely loved by people, become an attractive place, make people stay to forget to return.

2.Implementation plans

The music fountain equipment is to change the rhythm and intensity of the received music into control signals, and then transmit them to the industrial controller, which controls each frequency inverter separately through the bus.

Through upper machine using MODBUS music fountain dedicated bus protocol, each upper machine connected to dozens of frequency inverter, frequency inverter using MODBUS protocol,frequency inverter control, change frequency change the motor speed, also changed the pressure of the pump, the motor speed with the music tone, rhythm, and strength change, and the pump pressure change, spray file water has a change, achieve the effect of beautiful.

3. Application advantages

(1)FGI FD100 low voltage frequency inverter without speed sensor flux vector control, high speed accuracy, fast response speed;

(2)FGI FD100 low voltage frequency inverter phase protection, under voltage protection, overload protection, a variety of intelligent protection;

(3)The FGI FD100 low voltage frequency inverter has a new speed tracking function in the 0-80Hz range, speed tracking takes only 0.5 seconds, and SVC torque control is more flexible;

(4)FGI FD100 low voltage frequency inverter has excellent weak magnetism.
