In the music fountain, some companies use the current international most advanced distributed computer control system based on WINDOWS NT. The system has five characteristics: advanced, open, practical and safe. Automatic control technology is the most important technology in the music fountain:
The music signal processing system, a high level of use of international advanced technology of Chinese Academy of Sciences Institute of automation language recognition, developed a 32 bit computer music signal processing system (M UCS), music signal spectrum analysis and time delay processing to the main control machine to extract the effective components for the music fountain control signal, and the music any delay synchronizing signal, and music fountain.
Two, centralized decentralized control system of the fountain by the main control machine direct control, the main control machine has the following characteristics:
1 music signal acquisition function, according to the frequency characteristics of the extraction of active ingredients.
2 to diagnose the fault of the fountain equipment, it can diagnose the running state of the host, the leakage current and the working state of the driving cabinet. 3 Chinese menu type operating system, so that the operator can learn to operate in a short period of time, a variety of dynamic modeling with the musical fountain and the pattern change display function, make the operation personnel to observe the changes of the fountain through the computer screen can greatly facilitate the music fountain with music and operating personnel.
4 open structure, friendly man-machine interface, communication interface and programming skills are open to users, only through the two button mouse to complete the music fountain with music, so it is easy to make the music fountain with music library enriched, always give a person find everything fresh and new feeling. 5 direct control of music fountain, direct drive pump, inverter or server.
6 swing motor speed and direction control, maximum control of 1024 or more. The fountain controller uses the MUCS system can be connected with any audio (CD, tape recorders, live performances, music etc.) to ensure signal without distortion, the complete synchronization of music and fountain. Three, the safety and reliability of each of the 1 way control equipment are installed over voltage, over current, leakage protection device, once fault occurs, can automatically cut off the power supply, reliable protection of the road fountain equipment without loss, ensure the safety of the people.
