音乐控制的喷泉

Music Fountain Control Music fountain control states of water and lamps with musical characteristic. A good musical fountain is a wonderful artwork, which may make our environment more beautiful and joyful. And its control system is the key technique. Music Fountain Control System The Music Fountainemploys a kind of on-spot industrial control system that incorporates thelatest advanced scientific technologies prevailing around the world, includingmusic control, programmable control and intelligent control technologies. The master controlsystem of the music fountain consisting of multi-media industrial computers, iscapable to recognize the melody, rhythm, volume and frequency of the musicpieces and realize the real-time control of the whole system and thesynchronization of water and music. It is set up with the convenient operationinterfaces and has the function of programming music tracks. There are threekinds of MF control systems: centralized control, on-spot bus control and networkbus control. (1) Centralized Control System The centralized control system has aradiated cabling structure and is suitable for such small size MF as there areno too much water patterns and the control room is nearby the pools. Becausethe cost invested on cabling will increase if the pools are afar from thecontrol room. (2) On-spot Bus Control System On-spot bus is a serial data communicationlink which connects the basic local controls to its upper controls, i.e. 485bus and CAN bus. On-spot bus has the following advantages: One transmission line is able to controlmore than one equipment. The control system is thereby simplified, which leadsto the shorter construction period and easier installation and maintenance. On-spot bus employs the digitalcommunication technology which has the character of anti-jamming and highaccuracy. Its more reliable and flexible due to thelocal control function. (3) Network Bus Control System Network Bus Control System has anfundamental improvement in performance compared with On-spot Bus Control Systemthough they are quite similar in structure. a. Network Bus Control is a completelydistributed system. It speeds up the electrical system and satisfy thereal-time control need of music fountains. Also, it runs more stable. b. It can support the bus controlstructure, radiated structure as well as the mixed ones. c. The main difference between Network BusControl and Local Bus Control is that the former employs a special networkoperation system to ensure the operation of all equipment around the network.. d. The commissioning and maintenance of theelectrical system are more convenient. Programmable Fountain The control systemof the programmable fountain uses the timing routine to control the change ofwater patterns. The pumps can be either controlled by switches or by variablefrequency drive. When there are color lights to illuminate the water, thatsthe so-called "Colored Programmable Fountain". Special Fountains Entertainment fountain, waterfalls,super-high fountain and other specialty fountains as well all need specialcontrol system.Music Fountain ControlCabinet Music Fountain Control Cabinet adopts speical power system for musicfountain, which meets the demands better. Fountain cabinets allocate powercircut for each water pattern in accordance with the actual power allocationand equipment type. All cabinets are GGD standard products with certificatesfrom authorities. The electrical appliances are world-famous brands like Schneider and Siemens The system will be equiped with protection device for over-voltage,over-ampherage, Volt-shortage, phase-fault and short-circut, which guaranteesthe systems reliable ans safe operation.
