The working principle of the musical fountain is to control the water column according to the played music to achieve the effect of synchronization with the music. The water column is controlled by a water pump, and the water pump is composed of a three-phase asynchronous motor. If the speed of the phase asynchronous motor is connected to the industrial frequency power supply, the speed will not change. The frequency converter is a device specifically designed for motor speed regulation. The frequency converter controls the speed of the motor to change the water column.

Changing the frequency changes the speed of the motor, and also changes the pressure of the water pump. The different frequencies of the music are processed by the microcontroller and sent to the control end of the variable frequency motor, so that the motor speed changes with the tone, rhythm, and frequency of the music. As the strength changes, the pressure of the water pump changes accordingly, and the sprayed water changes in height.

The Highest Fountain

At 19:58 on August 1, 2007, a 100-meter-high water column spewed out from the Hunjiang River in Tonghua City, creating a spectacular sight. It is understood that this is the musical fountain with the highest eruption in the three northeastern provinces, and it is also one of the components of the landscape belt construction project along the Hunjiang River in Tonghua. At the completion ceremony of the project that night, it was not the main leaders who cut the ribbon, but citizen representatives.

According to reports, this is the musical fountain with the highest eruption in the three northeastern provinces, with a total investment of more than 20 million yuan. At the same time, it is also part of the construction project of the landscape belt along the Hunjiang River in Tonghua, becoming a new landscape in Tonghua City.
