The Realization Method of Music Fountain Automatic Control Technology

Automatic control technology is the most critical technology in music fountain. Its main characteristics are as follows:

I. High Level Music Signal Processing System

Using the international advanced technology of language recognition in CAS Automation Institute, a 32-bit computer processing system (MCUS) for music signals is developed. The system performs spectrum analysis and delay processing of music signals, extracts the effective components of music signals suitable for fountain control and sends them to the main computer. The fountain can be delayed arbitrarily to make the fountain work. Synchronize with music.

II. Centralized and decentralized control system The fountain is directly controlled by a master computer, which has the following characteristics:

1. Music signal acquisition function, extracting effective components according to frequency characteristics.

2. Fault diagnosis of fountain equipment can diagnose the running status of main engine, leakage and working status of driving cabinet.

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

4. Open structure, friendly man-machine interface, open communication interface and programming skills to users, only two keys through the mouse can complete music fountain matching, so it is easy to make music fountain matching library constantly enriched, always give people a fresh feeling.

5. Direct control of music fountain, direct drive pump, frequency converter or server.

6. Swing speed and direction control of the swing motor, maximum control 1024 or more. The fountain controller adopts MUCS system, which can connect with any sound source (CD player, tape recorder, live performance, etc.) and synchronize the music and fountain completely without distortion of the music signal.

III. Safety and reliability

1. Over-voltage, over-current and leakage protection devices are installed in each controlled equipment. Once a fault occurs, it can automatically cut off the power supply, reliably protect the fountain equipment of this road from loss and ensure personal safety.
