technical field

The invention relates to a treadmill, in particular to a speed control method and system of the treadmill.

Background technique

With the improvement of people's fitness awareness, the use of various fitness equipment is also increasing. Treadmill is a fitness equipment that everyone often chooses. The current treadmill needs to manually set the running speed of the treadmill through buttons, knobs, remote control or sliding screen before running, and then the treadmill is driven by the motor to run the running belt at the set speed. Can run at a set speed. If you need to change the running speed, you need to stop running and reset the running speed of the treadmill, or complete the operation of resetting the running speed of the treadmill during running, which is very inconvenient to use.

Chinese invention patent specification CN105999619B discloses a control method of an intelligent treadmill, which is characterized in that it includes the following steps: Step 1: Set the upper and lower limit values of the position in the holding area on the host computer; Step 2: Set the upper and lower limit values of the position in the host computer on the host computer Adjust the proportional value at a fixed speed; Step 3: The infrared array sensor obtains the position of the center of gravity of the human body; Step 4: The processor module detects whether the center of gravity of the human body is in the holding area. If the center of gravity of the human body is not in the acceleration area, the next step will be executed. If the center of gravity of the human body is in the acceleration area, the acceleration signal will be transmitted. To the motor driver, the motor driver accelerates the motor to complete the speed control of the treadmill, wherein, the acceleration adjustment amount = (the actual position of the center of gravity - the upper limit value of the position) * the speed adjustment ratio value; Step 6: The processor module detects the human body Whether the center of gravity is in the deceleration zone, if the body's center of gravity is not in the deceleration zone, go back to step 3, if the body's center of gravity is in the deceleration zone, transmit a deceleration signal to the motor driver, and the motor driver decelerates the motor to complete the speed of the treadmill control, wherein, the deceleration adjustment amount=(the lower limit of the position - the actual position of the center of gravity) * the speed adjustment ratio; wherein, the step 3 includes:

Step 31: The infrared array sensor acquires the human body footstep position data, and transmits it to the processor module for processing; Step 32: The processor module compares the current footstep position data with the previous footstep position data, if the current footstep position data is greater than the previous footstep position data Step position data, then return to step 31, if the current step position data is less than the last step position data, then execute the next step; Step 33: save the last step position data, and record it as the data maximum value X1, at this time, the human footsteps Closest to the front end of the treadmill; Step 34: The infrared array sensor continues to obtain the human footstep position data, and continues to transmit it to the processor module for processing; Step 35: The processor module compares the current footstep position data with the previous footstep position data. Compare, if the current step position data is less than the last step position data, then return to step 34, if the current step position data is greater than the last step position data, then execute the next step; Step 36: save the last step position data, and record as The minimum value of the data is X2. At this time, the human footsteps are closest to the rear end of the treadmill; Step 37: Calculate the position data X of the center of gravity of the human body, X=(X1+X2)/2. The speed control method of this treadmill divides the running belt into an acceleration area, a holding area, and a deceleration area. By calculating which area the center of gravity of the human body is in, the corresponding speed adjustment is made: if the center of gravity of the human body is in the acceleration area, then the If the center of gravity of the human body is in the holding area, the running belt will run at a uniform speed; if the center of gravity of the human body is in the deceleration area, then the running belt will be decelerated. It is inconvenient, the speed control process is complicated, and it is impossible to judge whether the speed needs to be adjusted when the center of gravity of the human body is located at the junction of the two zones. In the treadmill after partition, the design of the running belt is too complicated and the manufacturing cost is high.

Therefore, there is a need for a technique to control the speed of the treadmill.
