In step S25, the average value (Gw), the maximum value (Gpeak), and the minimum value (G... calculated in step S24 are calculated as the acceleration signal G1(x, y, z) in the current time interval T1. The peak parameter Up_b0und and the valley parameter L〇w_b〇und of the two-component 匕 waveform, the specific operation equation is as shown in the above equation (丨), (u. Then proceeds to step S26. 110616 12 201017134 at step S26 Medium, dynamically adjusting the current cavitation valley parameter, the current peak parameter of the acceleration (4), and the value of the gossip and 〇唬匕1〇唬匕(x, y, z) in the vertical direction, and the minimum value, that is, in step S25* Calculated wave = =: P: b wide and trough parameter one. _ as current time = wave quart parameter and trough parameter, calculated by (4) S24 it: internal acceleration signal Gi(x, y, z) in vertical The component of the direction G; the large value and the minimum value respectively represent the maximum value and the minimum value of the current acceleration signal 1 〇 = straight direction. Then, the process proceeds to step S27 to analyze the acceleration signal in the current time interval n. ^ ( X, y, z ) The waveform of the component Q in the vertical direction Step S28. In step S28, the towel 'determines the accelerated calving in the current time interval T1, and the waveform characteristic of the component 匕 in the vertical direction (χ, γ'ζ) is: the peak and the trough of the connected, if yes, then Go to step S29, if no, return to step S21 to sense the acceleration signal & (x, y, z) generated by the up and down oscillation of the human body during the walking-time interval T2 (T2=T1=T〇) It should be noted that, in step 27, the waveform of the component Gz of the acceleration signal Gi(x, y, z) in the vertical direction within the current time interval 为 is detected in several bands to determine the input. Whether the waveform is a complete sinusoidal waveform, wherein the input waveform needs to be detected 5 times from state=〇 to State=4. State=0 is the initial state of waveform judgment, when the waveform rises above the above equation (1) Calculate the size of Up_b〇un°d Π0616 13 201017134 and enter state=l, indicating that the waveform has met the amplitude requirement of the sine wave Sin rising phase; the waveform is inverted to fall, and the gamma (four) is entered, indicating that the waveform has a peak , entering the sine wave Sin falling phase When the waveform falls more than the magnitude of L〇w-b〇und obtained by the above equation (2), entering the state 3 indicates that the waveform has met the amplitude of the sine wave Sin falling phase, and although the waveform is inverted, Enter state=4, indicating that the waveform has crossed, and enter the final rising phase of the sine wave Sin wave. When the waveform rises above the above Gavg, the acceleration signal ❹Q (x, y, z) in the current time interval τι can be judged. The waveform of the component ^ in the vertical direction is a complete sinusoidal waveform. In step S29, the number of steps taken by the human body is increased by j. Further, after the step S29, the step of displaying the result of the step of walking the human body is included. Compared with the prior art, the step counter processing system and method of the present invention mainly senses an acceleration signal generated by the human body up and down (4) during walking of the human body and transmits the sensed acceleration signal to the center of the earth. The gravitational direction is used as a projection operation to obtain a waveform of a component of the acceleration signal generated in the vertical direction when the human body walks, and analyze whether the waveform characteristic of the component of the acceleration signal in the vertical direction is a continuous peak and a trough, and The result of the analysis is used as the basis for accumulating the number of steps. Since the invention adopts the waveform characteristic of analyzing the component of the acceleration k in the vertical direction caused by the up and down oscillation of the human body during the walking process of the human body, it can be accurately stepped as a metering unit, and the mechanical system of the conventional wristwatch type is avoided. The pendulum sensor needs the user's arm to naturally swing, and the pedometer can be sensed by the pedometer.] 06] 6 14 201017134 The state of the swing is measured, and the function caused by the function of the illusion is achieved.
