A fountain is a combination of specific shapes sprayed out of a sprinkler through a certain pressure when water or other liquids pass through a certain pressure. Nowadays, fountain is generally a fountain that relies entirely on fountain equipment. Mainly through the control of frequency converter to achieve rhythm and rhythm, music fountain in the form of water change is rich, with lighting to give people the real and intuitive sense of beauty. All kinds of swings in music fountain can make people feel the beauty of fountain. The emergence of radial swing is due to the swing mechanism under the surface of the water, making the scenery beautiful and moving, pleasing to the eyes and giving people a magical feeling, which is the expression of the development of the high technology in the times.
The change of position and speed of swing fountain is an important factor to produce swaying water style. The position sensor of fountain swinging mechanism should be waterproof and non contact location device. Holzer sensors, magnetic sensors, optical fiber sensors or magnets attracting rotary positions are often used. For example, the positioning device for a fountain swing mechanism using a position encoder includes a position encoder, a high speed counter, a control computer, and a communication interface, which are mounted on the swing motor axis. The connecting rod of the swing mechanism usually has a large gap. In order to achieve accurate positioning, the swing mechanism can only reach the positioning point from one direction to ensure its repetition precision. Therefore, when the wobble mechanism needs to stop, it must arrive at the location point from one direction at a time.
The positioning accuracy of the swing mechanism is affected by the torque and the torque. The motion moment is determined by the power supply voltage of the motor and the speed of the motion before parking, while the resistance moment is composed of the friction force of the swing mechanism, the speed of the water flow, and the wind around it. It can be seen that these factors are not predetermined. Therefore, in order to achieve the goal of precise positioning, we must change its control parameters every time. Generally speaking, there are two control parameters for the precise location of motors, namely, the magnitude of the DC braking current and the start-up and braking time. A more convenient way to control computer is to change the braking time.
In the control system, the motor braking time can be corrected by detecting the deviation of the point of arrival. According to the statistical data of the location deviation value of the swing mechanism, after the calculation of the mathematical model, the braking time is finally determinedA fountain is a combination of specific shapes sprayed out of a sprinkler through a certain pressure when water or other liquids pass through a certain pressure.
