The music program-controlled fountain is designed for entertainment and appreciation
is a movable fountain invented for entertainment and appreciation. It is designed according to aesthetics and often produces 3D effects. This effect is caused by sound waves or light waves passing through water particles. The core equipment of music program-controlled fountain control system is programmable controller, analog input and output module, frequency converter, etc. The use of physical waveform files can be divided into several parts, accuracy of 10 ms, basic functions and emotional impact of automatic recognition, lyric, happy, cheerful and other music, to a control signal, which is output to a specific peripheral control unit, visual and auditory perception after the signal output card synchronizes the process.
How to control the music program-controlled fountain? The control is divided into two parts: one is the fixed program operation, the other is the music control part. Music control part: when you need to use it, you can press this button to analog input and output module to capture and play back audio intensity music, a / D conversion, compare operation, and output the results to analog input port converter, control the output frequency of converter, control the speed of pump, and achieve the purpose of controlling the height of fountain. In practical application, attention should be paid to the characteristics of various nozzles. Generally, water film nozzles have poor wind resistance and are not suitable for outdoor wind; and sprays such as cedar sprays are more sensitive to changes in water level. Not only should we pay attention to changes in water level, but also suppress waves in corresponding pool design measures. For example, build a longer weir or underwater wall.
However, it is also conducive to the resonance of waves, hydraulic phenomena, the formation of pulsating fountains, and common wave surges, making the water jet regularly jump, high and low changes. At present, there are many high-tech fountain equipment, which can also be used for water art landscape. The bright spring and spring jump jet are very stable, looking like a glass rod, which can fall under the water accurately; the spring jump can be controlled by the length change of the water jet generated by the computer; the spring jump can smooth the control of the size of the fountain water ball. They are very interesting and unforgettable. Various high-tech nozzles and underwater motion machines and control components used in large-scale music nozzles and underwater music fountains also have a wide range of styles and availability.
In our opinion, the suitable water depth is 0.2 ~ 0.4m. Another advantage is that when the water turbidity is slightly higher, the impression is still clear. The top wall of the pool wall should be provided for tourists to sit and rest. The top of the pool wall is 0.30 to 0.45M from the ground. Besides artificial lakes, the surface of water should be higher than the ground. If the water level is low, it will feel like a deep pool. From the perspective of hydrophilicity, the more appropriate scale is the water surface, and the top wall of the pool is 0.2m, which is more reasonable.
