The control system is part of the musical fountain. Large-scale musical fountains are generally controlled by a programmable control system. For musical fountain designers, it is necessary to understand the control characteristics of large musical fountains in order to design a good plan.
The musical fountain works through a real-time control system. The larger the musical fountain control system, the more complex it is. However, whether it is a large-scale or general musical fountain system, the control program and music will be prepared in advance according to various music. Simultaneous playback, this is the most basic principle of the music fountain control system. Through the control system, you can control and output various water types, lights, etc. at will. The following will introduce the control characteristics of the large-scale music fountain.
Large-scale musical fountains are mainly found in some large squares, theme parks, and some broad lakes. Electrical equipment includes water pumps, lights, audio, frequency conversion, power distribution panels, etc. The total installed capacity is about thousands of kW. Intermittent change work, instantaneous voltage fluctuations and interference are particularly serious, especially the high frequency and high current of frequency conversion. Therefore, the upper computer and the lower computer are used in the real-time control of the music fountain, and the upper computer used for operation control is installed far away The equipment controls the computer room, and the place where the fountain can be observed is easy to monitor and control, and the lower-level computer that controls the power equipment is directly installed on the power distribution panel of the computer room. The upper computer generally adopts a computer, which can provide various operations of multimedia technology, text and graphics, and display interfaces to monitor the lower computer. The lower computer uses a single-chip microcomputer, PLC or industrial computer, but considering the anti-interference and harsh working environment and Better performance and price ratio generally use PLC.
The control methods of musical fountain mainly include real-time control and program control. Musical fountain has very low requirements for real-time control, because the combination of fountain lighting and water type is still limited, and many changes are regularly repeated. The program control method is actually a computer instead of manual operation to control the lower computer in real time. Therefore, the music to be played and the lighting to be matched with it should be arranged in time, and the control will be saved in the computer after the debugging is completed. Play music and the corresponding control sequence when it is officially played.
The control system of a large musical fountain is very complicated. With the continuous development of science and technology, the fountain control system is also constantly developing. I believe that the problem of music synchronization can be solved in the near future.
