step (2), the host (23) monitors the temperature of the springs (35) in real time through the temperature sensor (43), when the temperature of all the springs (35) reaches a specified value, the host (23) controls the display screen to display a ready window, and after a counting button is started under an observer point, the athlete can jump the rope;

step (3), in the process of rope skipping of the athlete, the processing module (11) monitors the numerical value of the angle sensor (10) in real time, and when the input shaft of the angle sensor (10) rotates 360 degrees in the same direction, the processing module (11) instructs the first partition in the storage module (12) to count for one time;

step (4), when the baroreceptor (3) is impacted once, the processing module (11) instructs a second partition in the storage module (12) to count once;

step (5), when the athlete jumps once, the pressure rod (22) at the bottom of the supporting plate (19) hits the piezoelectric crystal plate (21) once, so that the piezoelectric crystal plate (21) sends out a pulse current, and the host (23) calculates the jumping times of the athlete by monitoring the times of the pulse current sent out by the piezoelectric crystal plate (21) in real time;

and (6) when the rope skipping of the athlete is finished, the host (23) counts and analyzes the counting results of the step (3), the step (4) and the step (5), and then outputs and displays the counting results on the touch display screen (24).
