Fountains are not unfamiliar to us; we can see their presence in hotels, parks, and other places. There are various types of fountains, with musical fountains being particularly popular. They are often rhythmic and well-liked. Below, we analyze the reasons behind the rhythmic nature of musical fountains.
A typical musical fountain installed by fountain manufacturers is a combination of water or other liquids sprayed into specific shapes through nozzles under pressure. Nowadays, most fountains are artificial landscape fountains, primarily controlled by variable-frequency drives to achieve rhythm and melody. The water shapes in musical fountains are diverse, complemented by lighting to create a realistic and直观 sense of beauty. The various swaying movements in musical fountains evoke the graceful beauty of the water. The radial swaying is produced by a swinging mechanism below the water surface, making the water scene beautiful and captivating, offering a pleasant sensation, and reflecting the advancement of high-tech in the era.
The torque of motion depends on the motor's power voltage and the speed of movement before stopping, while the resistive torque is composed of the frictional force of the oscillating mechanism, the speed of water flow, and the surrounding wind force. It is evident that these are all factors that cannot be predetermined. Therefore, to achieve precise positioning, we alter the control parameters each time. Generally, for precise positioning using motor energy consumption braking, there are two control parameters: the size of the DC braking current and the start-braking time. A convenient method for computer control is to adjust the braking time.
In the control system, the braking time of the electric motor can be corrected by detecting the deviation from the到位 point. Based on the statistical data of the positioning deviation value of the swing mechanism, the braking time is determined through mathematical model calculations.
Our analysis of the rhythmic reasons behind musical fountains comes to a close here. As society progresses, the demand for musical fountains will continually increase. In the future, their various performance aspects will only improve, and there will be a growing variety of such products, expanding the range of choices significantly.
