Abstract: A digital exercise equipment cluster system comprises a computation unit, a display unit, stereo equipment, environmental effects equipment and multiple pieces of exercise equipment installed with electronic control equipment. The computation unit is connected to the display unit, stereo equipment and environmental effects equipment, respectively, and is connected to the electronic control equipment on the exercise equipment through interface circuits. The exercise equipment is any one of a dynamic bicycle, a treadmill, an elliptical trainer, an indoor rower. The system may form multiple pieces of exercise equipment into one exercise equipment cluster system capable of general scheduling and independent operations, so as to provide a basic platform for group activities of multiple exercisers.

Abstract: A treadmill with man-machine interaction speed regulation and a control method thereof are presented. The treadmill includes an arm swinging detection unit for detecting an arm swinging amplitude or frequency. When a user runs on the treadmill, the arm swinging amplitude or frequency of the user can be detected by the arm swinging detection unit. In the situation that a variation of the arm swinging amplitude or frequency is greater than a preset threshold value, a new transmission speed of a treadmill belt is worked out according to a new arm swinging amplitude or frequency, and the speed of the treadmill is regulated to the new speed automatically. Otherwise, the treadmill belt keeps the former transmission speed. The treadmill speed is automatically regulated according to dynamically monitored arm swinging information, which allows the user to change the transmission speed of the treadmill belt in a natural way.
