Patent ID: 7048676

Claim:
A method of controlling a treadmill running, which the treadmill has a microprocessor, a power, a control panel, a motor and at least a sensor, wherein signals are inputted from the control panel to order the microprocessor controlling the motor, and the motor drives a belt running via a transmission device, and the sensor senses an actual loading of the motor, comprising the step of: turning on the power: operating the control panel to turn on the power; standby: turning the microprocessor, the motor and the sensor to standby conditions respectively after the power is turned on; single input: inputting singles from the control panel; determination of a running status of the motor: the sensor detecting the motor to determining whether the motor is running or not, wherein if the motor 14 does not run, the microprocessor makes a malfunction decision, and if the motor runs, go to a following step of the present invention; determination of attributions: the sensor detecting the motor whether it is an idle running condition or a loading running condition, wherein if the motor is in the idle running condition, the microprocessor enters an idle running step, and if the motor is in the loading running condition, the microprocessor enters a loading running step; the idle running step: wherein the idle running indicates that nobody runs on the treadmill, and the sensor keeps sensing the motor for determination of the attributions, and if the motor keeps in the idle running, the microprocessor controls the motor running until a predetermined setting time is up or the control panel is operated to stop the motor, and then turns the motor to the standby condition after the motor has been stopped; the loading running step: wherein the motor 14 having loading indicates that a user stands and runs on the treadmill; the sensor detecting the motor continuously, and the microprocessor determining whether the motor is in a continuous loading condition or an intermittent loading condition; the continuous loading condition: wherein the motor in the continuous loading condition indicates that user stops running and stands on the belt or the belt is jammed; the microprocessor shutting the motor to avoid accident, and turning the motor to the standby condition; the intermittent loading condition: wherein the motor in the intermittent loading condition indicates that user is running or walking on the belt, and every steps provide the motor a loading respectively; the microprocessor and the sensor detecting the motor 14 having the loading intermittently and repeatedly in a predetermined time that indicates user is running on the treadmill, and the sensor keeping sensing the motor, and the microprocessor controlling the running until the predetermined time is up or the control panel is operated to stop the motor; wherein no loading to the motor in the predetermined time indicates that there is nobody running or walking on the treadmill; the microprocessor shutting the motor and turning the motor to the standby condition.
