Treadmill with Man-Machine Interaction Speed Regulation and Control Method Thereof

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.
