The location of the swinging music fountain and the change of fitness movement rate are the key factors that cause the swinging water type free and easy charm. The phase sensor of the swing organization of the music fountain should be moisture-proof and non-touching positioning equipment. Hall sensors induced by magnets, photoelectric switches correctly guided by optical fiber lines or servo motors at rotating parts attracted by magnets are often selected. For example, the positioning equipment for the swing organization of music fountain with the selected position servo motor includes the position servo motor installed on the swing motor shaft, the speed electronic counter, the operation electronic computer and its computer interface, etc. Because the crankshaft of swinging tissue generally has a large gap, so as to achieve accurate positioning, only when the swinging tissue reaches the selected point from one direction can its repeated precision be ensured. Therefore, when the swing organization must park, it must arrive at the selected point from one direction every time. The accuracy level of swinging tissue is endangered by the exercise torque and resistance torque. The exercise torque is determined by the power supply voltage of the motor and the exercise speed before parking, while the resistance torque is generated by the sliding friction of swinging tissue, the speed of running water, and the surrounding wind speed. It can be seen that all these elements cannot be clarified in advance. Therefore, in order to achieve the goal of accurate positioning, people must change its main parameters every time. There are generally two main parameters for precise positioning of the motor energy-consuming braking system, namely, the size of the current of the DC braking system and the time for starting the braking system. A convenient way to control the computer system is to change the braking system time.In the automatic control system, the motor braking system time can be adjusted by the error of inspection and time point. According to the data statistics of the precise positioning error value of the swing organization, the braking system time is finally determined through the calculation of the mathematical analysis model.
