The number of steps is 1.0. Similarly, when the user steps one step, if the bump 321 does not pass all the photoelectric sensing counters, that is, when the second transmission shaft 32 is less than one turn, the number of turns of the speaker that can be rotated by the voice prompt is less than 1 or the number of prompt steps. If it is greater than 1, the step processing module increases the number of steps displayed by the step display screen 38 by 0.X (X is an integer from 1 to 9), thereby prompting the user to adjust the control knob 37 to the display screen every time one step or one step is taken. The number of steps displayed is 1.0, which enables accurate step counting without the use of expensive servo motors and distance sensors. Due to the main use of mechanical transmission sensing, the reliability is high and the user's excessive or too small steps can be corrected. It can be used for step counting when switching to mechanical running mode. The main motor can realize accurate step counting without opening, vibration, low noise, energy saving and environmental protection.
