Embodiment 1
[0052] Example 1, such as figure 2 As shown, the ultrasonic ranging probe is used to detect the position and inclination angle of the upper body of the moving human body. Ultrasonic sensors use the echo time to precisely calculate the distance between the sensor and reflective objects. By continuously monitoring distance changes, the speed of movement can also be calculated. The distance detected by multiple position sensors can comprehensively calculate the inclination angle of the object reflecting the sound wave.
[0053] Using the distance information, the driving motor can be controlled to continuously adjust the rotational speed, so that the moving body can be kept in the middle section of the running device. When the moving body runs faster and the upper body approaches the detector, the motor of the treadmill rotates faster; when the running speed of the moving body decreases and gradually moves away from the detector, the machine can slow down. If the movement of ...
Embodiment 2
[0060] Example 2, such as image 3 , Figure 4 As shown, on the basis of Embodiment 1, pedal signal detection can be added. The time difference of the signals between multiple vibration detection probes can be calculated by using the vibration sensor signals, so as to determine the approximate position of the foothold on the pedal. If the two adjacent footholds evenly fall in the safe interval, it indicates that the moving body is in a stable state. If there is a sudden confusion in the stride length or the step interval, it is likely that a motion imbalance has occurred and the control system needs to slow down or stop as soon as possible.
[0061] The calculation of the time difference of the vibration signal is completed by the CPU (single chip microcomputer) of the intelligent control system. After the vibration waveform signal is collected by the AD port, it is obtained through mathematical calculations such as correlation operations.
