The music fountain is a music control system based on the program control fountain. The computer decodes and encodes the audio and MIDI signals, and finally outputs the signal to the control system to make the shape and lighting of the fountain and music. Keeping in sync to achieve the perfect combination of fountain water, lighting and color changes and musical mood, making fountain performance more vivid and rich. Musical fountain: It can change according to the level of music. Users can write their favorite music programs in the editing interface.
Changing the frequency changes the speed of the motor, which changes the pressure of the pump. The different frequencies of the music are sent to the control end of the variable frequency motor by the single-chip microcomputer, so that the motor speed changes with the pitch, rhythm, and strength of the music. With the change, the water of the sneeze has a high and low change, and it is a pump that is controlled by several sets of equipment to control the fountains of multiple sets of nozzles.
The rhythm and intensity of the music is converted into a control signal, which in turn controls a voltage control device. After the power supply passes through the voltage control device, the output voltage also changes with the music, and then the water pump motor is controlled.
The music fountain control system, the software uses the physical waveform of the music file, divides it into several sections with an accuracy of ten milliseconds, and automatically recognizes the basic emotional characteristics of the music such as shock, miss, lyric, joy, passion, sadness, joy, and warmth. , converted into control signal, after synchronous processing, output to the peripheral specific control unit through the signal output card, that is, control the submersible pump, solenoid valve, underwater lantern and inverter and other actuators according to the water type configuration rules, and the visual perception and The auditory feelings are integrated.
