Control system of an electric treadmill

Abstract

The present invention provides an auto-control system of an electric treadmill, which includes at least a speed control unit, a slope control unit and a calorific capacity setting unit. After the value of calorific capacity setting unit is set, the speed control unit and slope control unit allow for automatic matching of an operational value according to the set-value. When either the speed control unit or slope control unit is activated with varying values, the other one will be automatically adjusted. A predefined value of energy consumption through the calorific capacity setting unit can be set, while the control system enables automatic matching of the speed and slope, so that the user achieves the preset energy consumption within a preset period of time. Moreover, if either speed or slope is manually adjusted, the other option will be automatically adjusted to maintain the preset value of energy consumption.

1 . An auto-control system of an electric treadmill, the control system comprising:
 a speed control unit;   a slope control unit; and   a calorific capacity setting unit;   having a set value, said speed control unit and slope control unit automatic matching an operational value according to said set value;   said speed control unit or said slope control unit being activated with a varying value, each other being automatically adjusted.   
   
   
       2 . The system defined in  claim 1 , wherein said set value of said calorific capacity setting unit is a set-value of the control system, or a value manually set by a user.
