Problems solved by technology

However, this method of using an optical sensor to control the state of the walking belt has a problem that the control speed is inaccurate because the use of the optical sensor only detects the position of the user's foot regardless of whether it is a left foot or a right foot, and then controls the speed
In addition, there is also a problem in this device that when the light emitted by the light emitting unit is weak, for example, because the light emitting unit 15a and the light receiving unit 15b are installed on the left and right sides of the walking belt respectively, while the light emitting unit 15a and the light An excessively large distance is formed between the receiving units 15b, and at this time, the position of the user's footsteps cannot be accurately detected.

Abstract

The present invention relates to an automatic speed-controlled treadmill using a pressure sensor array and a method of operating the same. The automatic speed-controlled treadmill includes a walking belt, a pressure sensor array including pressure sensors for detecting loads of the exerciser's feet and outputting the detected loads of the feet as load detection signals, a pace speed status storage unit for storing a pace speed and variation in pace speed of the exerciser, and a control unit provided with an algorithm for calculating a pace speed of the exerciser using the load detection signals, calculating a difference between a previous pace speed and a current pace speed as the variation in pace speed, calculating the exercise center of the exerciser, and proportionally accelerating / decelerating a driving speed of the walking belt in consideration of the variation in pace speed and the exercise center.

Description

technical field [0001] The present invention relates to an automatic speed control treadmill using a pressure sensor array and its operating method, and has the technical characteristics of being able to detect the load of the exerciser, calculate the change of the pace and the position of the exercise center, and then automatically control the driving speed of the walking belt . Background technique [0002] Generally, a treadmill is a kind of exercise equipment that enables running or walking to be performed indoors. Such as figure 1 As shown in (a), the treadmill includes a walking belt 12, a driving device for moving the walking belt 12, and a control device for controlling the driving device. The driving device includes rollers for supporting the walking belt 12 and a motor for driving the rollers. The control device controls the drive device connected to the motor. According to this typical treadmill, the exerciser drives the motor through the input module 11 to mo...
