Description
METHOD OF CONTROLLING RUNNING STATUS OF TREADMILL
Fieid of the Invention The present invention relates generally to a treadmill, and more particularly to a method of controlling the running status of a treadmill.
Background and Description of the Related Art
A conventional electrical treadmill has a motor to drive a belt, on which a user can run. The user also can adjust the speed of the belt by controlling the motor, such thai a user can choose a suitable condition to exercise on the treadmill.
For the safety of the user, the conventional electrical treadmill is provided with a safety apparatus to detect the speed of motor. If the speed of the motor is lower than a predetermined value, which indicate that the belt may be jammed, the safety apparatus will stop the motor automatically for the safety of user.
In case of a heavier user running on the belt of the treadmill in a lower running speed, and at the moment of the user stepping on the belt, the speed of the motor is lowered because of the suddenly greater loading. Al this condition, the safety apparatus may trigger a false alarm and stop the motor immediately to slop the exercise.
A feedback control system is provided to overcome the drawback described above.
The feedback control system has a sensor to detect the voltage and current of the motor and to control the speed of motor according to the voltage and current. For example, in the case of a heavier user running on the belt of he/she running faster that increase the loading of the motor, the sensor will detect that and increases the voltage and current supplying to the motor to increase the speed or torque of the motor that would approach the speed of the belt to the actual condition. For an opposite condition, the safety apparatus will decrease the voltage and current supplied to the motor to lower the speed or torque of the motor.
1 0 If the belt is jammed by extremities, a shoelace or clothes of user that increase the loading of the motor, the safety apparatus increases the voltage and current supplying to the motor after it detect that condition that would make the user in trouble to get out, and he/she might fall down and get injured in this condition. If the user get off the treadmill, the safety apparatus only detects the loading of the motor is lower and decreases the voltage and current supplying to the motor, in this condition, the belt keeps running with nobody on it. If the treadmill has not been turned off, and a child steps on it, the child would get injured.
In addition, if the treadmill is shown in an exhibition, and no one stands on the belt, the safety apparatus will restrict the belt running in a lower speed that might mistake the consumes that the treadmill only can run in a lower speed.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a method of controlling a running status of a treadmill, which provides a sensor detecting a motor whether it is an idle running condition or a loading running condition. The idle running condition indicates that nobody on the treadmill, so that the motor keeps a designated running speed. If the motor is in the loading running condition, it has to be determined whether it is in continuous loading condition or an intermittent loading condition. The intermittent loading condition indicates that user is running on the treadmill, so that the motor keeps a designated running speed. The continuous loading condition indicates that user has stopped running but still standing on the treadmill or the belt is jammed, so that the motor is shut. The method of the present Invention provides the treadmill to be shown and safety stopped.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG 1 is a block chart of the elements of a preferred embodiment of the present invention, and FIG. 2 is a flow chart of the preferred embodiment of the present invention.
DETAILED DESCRiPTION OF THE INVENTION
As shown in FIG 1 and FIG. 2, the FIGS. Only show a preferred embodiment of the present invention that does not restrict the scope of the present invention only.
A treadmill of the preferred embodiment of the present invention has a microprocessor 11, a power 12, a control panel 13, a motor 14 and at least a sensor 15.
Signals can be fed back between the sensor 15 and the microprocessor ii. The control panel 13 is manipulative to input signals to control the motor 14 via the microprocessor 11. The motor 14 drives a belt (not shown) of the treadmill running via a transmjssjon device 16. The sensor 15 detects an actual loading of the motor 14.
As shown in FIG. 2, a method of controlling the treadmill comprises the steps of: Turning on the power: To operate the control panel 13 to turn on the power.
Standby: The microprocessor 11, the motor 14 and the sensor 15 are tuned to standby conditions after the power is on.
Signal input: To input predetermined signals via the control panel 13.
Determination of a running status of the motor: The sensor 15 senses the motor for determination of the motor 14 running or not. If the motor 14 does not run, the microprocessor 11 makes a malfunction decision.
If the motor runs, go to next step.
Determination of attribution: The sensor 15 detects the motor 14 whether it is an idle running condition or a loading running condition. The variation of the voltage and current of the motor 14 are detected by the sensor 1 5 to determine the motor 14 in the idle running condition or the loading running condition, if the motor 14 is in the id]e running condition, the microprocessor 11 enters an idle running step; if the motor 14 is in the loading running condition, the microprocessor 11 enters a loading running step.
Idle running step: The idle running indicates that nobody runs on the treadmill, and the sensor keeps sensing the motor 14 for determination of attribution. If the motor 14 keeps in the idle running, the microprocessor turns the motor 14 off after a predetermined time.
The motor 14 is turned to the standby condition when it is off. If the motor 14 is detected that it has a loading, which means a user stands and runs on it, the mIcroprocessor ii enters the loading running step.
Loading running step: The motor 14 having loading indicates that a user stands and runs on it. The sensor 15 detects the motor 14 continuously, and the microprocessor 11 determines whether it is a continuous loading condition or an intermittent loading condition.
Continuous loading condition: If the motor 1 4 is detected to be the continuous loading condition, which indicate that user stops running and stands on the belt or the belt is jammed by extremities, a shoelace or clothes of user, the microprocessor 11 shuts the motor 14 to avoid accident, and the motor is turned to the standby condition.
Intermittent loading condition: The motor 14 is detected to be the intermittent loading condition that indicate that user is running or walking on the belt, and every steps provide loading to the motor 14, and the motor 14 is detected having loading intermittently and repeatedly. Such as, the motor 14 is detected having a loading, and the next loading is detected in a predetermined time (such as two second) after. In this condition, the sensor 15 detects the motor 14 continuously, and the microprocessor 11 controls the motor 14 for a designated running. Until the predetermined time is up, the microprocessor 11 shut the motor 14. The motor 14 is shut also when user operates the control panel 13 to stop the motor 14. If there is n another loading to the motor 14 in the predetermined time that indicate that there is nobody running or walking on the belt, the microprocessor ii shuts the motor 14 and turns it to the standby condition.
The method of the present invention provides the sensor 15 to detect the running status of the motor 14 at initial to determine whether the motor 14 is in the idle running condition or in the loading rwrning condition verify whether the treadmill is in use or it just put there for exhibition. If the treadmill is in the latter condition, the treadmill is taken care by people, and there is no safety issue, so that the microprocessor 11 controls the motor 14 running continuously according to the input signals to shows the performance of the treadmill until the time or the order is up.
If the treadmill is in the use condition, the sensor 15 and the microprocessor 11 determine whether the motor 14 is in the continuous loading condition or in the intermittent loading condition. If the motor 14 is determined in the intermittent loading condition that indicate someone is running on the treadmill, the microprocessor 11 controls the motor 14 rurming according to order until the time is up or the user stop it via the control panel 13.
If the motor 14 is determined in the continuous loading condition that indicates the user stops running or the belt is jammed, the microprocessor 11 shuts the motor. To compare with the conventional device, which the feedback control system increases the speed and torque of the motor while the motor is in the continuous loading condition, the present invention provides a safety condition in user.
If the motor is in the intermittent loading condition, and there is no further loading to the motor in the predetermined time that indicates user has left, the microprocessor 11 shuts the motor 14 to avoid accident.
In conclusion, the method of present invention not only identifies the shown condition and the actual use condition, but also automatically stops the treadmill when user leaves. The method of the present invention further can fully stop the treadmill whcn the belt is jammed to control the treadmill in both conditions of the shown condition and the actual use condition.
