The most critical technology in the music fountain is automatic control technology

1. High-level music signal processing system

Using the internationally leading technology in language recognition where the Chinese Academy of Sciences automation is located, a music signal 32-bit computer processing system (MUCS) was developed to perform spectrum analysis and delay processing of the music signal, extract the effective components of the music signal suitable for fountain control and send it to the host Control the machine, and can delay the music signal arbitrarily, so that the fountain and music are synchronized.

Second, centralized decentralized control system　　The fountain is directly controlled by the main control machine, which has the following characteristics:

1. Music signal collection function, extract effective components according to frequency characteristics.

2. Diagnose the fault of the fountain equipment, and can diagnose the running state of the host, the leakage and the working state of the drive cabinet.

3. The Chinese menu operating system enables the operator to learn to operate in a short time. It has various dynamic modeling and pattern change display functions of the music fountain, allowing the operator to observe various changes of the fountain through the computer screen. The earth facilitates the use of music tunes and operators.

4. Open structure, friendly man-machine interface, communication interface and programming skills are open to users, only two keys of the mouse can complete the music fountain’s music composition, so that it is easy to make the music fountain music library constantly enriched. Gives a refreshing feeling.

5. Direct control of the music fountain, directly drive the pump, inverter or server.

6. The swing speed and direction control of the swing motor, the maximum control amount is 1024 or more. The fountain controller adopts the MUCS system, which can be connected to any sound source (CD player, recorder, live performance, etc.), and the music is completely synchronized with the fountain under the condition that the music signal is not distorted.

3. Safety and reliability

1. Each channel controlled equipment is installed with over-voltage, over-current and leakage protection devices. Once a failure occurs, it can automatically cut off the power supply, reliably protect the fountain equipment of this channel from loss and ensure personal safety.
