[0038] As an illustrative example, Figure 5 It is the signal collected when a volunteer steps forward at the Fresnel lens 2 at a walking speed. Figure 5 Among them, the signal curve segment 17 is the signal when the human body is still, and the signal peak 18 and the signal valley 19 correspond to the signal when the human body walks 1 step and 2 steps respectively. Use the peak-seeking algorithm to obtain the number of actions N=20; Image 6 is true Figure 5 The signal spectrogram obtained by Fourier analysis of the time domain signal, from Image 6It can be seen that the signal frequency is 0.8Hz, and the obtained step frequency is F=60*0.8*2=96 steps / min. The exercise time is T=20 / 96=0.21min; the volunteer is a male, with a weight of 70kg and a height of 185cm; input these parameters into the calculation unit, according to the empirical formula:
[0039] Walking energy expenditure / kcal=0.53H+0.58W+0.37F+1.51T-145.03
[0040] =0.53×185+0.58×70+0.37×9...
