Jet Principle

Behind the water curtain wall of the southernmost viewing platform of the musical fountain, a huge and mysterious control center is hidden inside. This is the "brain" that controls the normal operation of the fountain system. ".

There are 101 control cabinets neatly arranged in the underground control center. When you open the cabinet door, there are densely packed inverters inside. This is the frequency conversion cabinet that controls the fountain. Each frequency conversion switch controls a fountain nozzle independently. There are 1,024 ground nozzles in the Big Wild Goose Pagoda Fountain. Each ground nozzle is connected to a water pump, which is controlled by a frequency converter. During the performance, after the main control computer sends instructions to the frequency converter, the water pump will 'pull out' varying amounts of water from the pool according to the power of the frequency converter, and then spray it out through the nozzle.
