[0003] With the development of electronic devices, users are paying more and more attention to their daily sports. Step counting devices can record steps of walking or running in the daily activities of users, so as to provide the users with information on the number of moving steps, which is convenient for the users to determine the amount of exercise and energy consumption according to the information on the number of moving steps.

[0004] In the existing step counting methods, an acceleration sensor is generally used to collect acceleration data of the user while walking, and when effective peaks in the acceleration data reach a certain number, the user's walking steps are updated. However, in real life, users may stop and go during the walking process, and in this case, the effective peaks collected by the step counting device may not reach a predetermined number, thus in the process, the step counting device may still judge that the user has not walked, so that the step counting device cannot accurately record the number of walking steps of the user, resulting in low step counting accuracy of the step counting device.

[0066] The present disclosure provides a step counting method, a step counting device and a computer readable storage medium.

[0067] Referring to FIG. 2, the method includes:

• • [0068] S100, obtaining acceleration data, the acceleration data including effective peaks.

[0069] Here, the step counting device includes an acceleration sensor, and the acceleration data is data collected by the acceleration sensor of the step counting device. Specifically, the acceleration data is waveform data that changes with time. When the user wears the step counting device to perform an action, the acceleration sensor receives a change of the acceleration caused by the user's movement, and represents it in the form of a waveform. During the user's movement, the user walks through an alternating swing of the left and right hands and a sequential movement of the left and right feet, and in the walking process, the acceleration data detected by the acceleration sensor changes periodically up and down, accordingly, the user's movement state can be determined according to the acceleration data. When the user performs other actions, a regular periodic change of the waveform cannot be maintained, so that the step counting device can determine the user's walking steps according to the change of waveform.

[0070] The method includes:

• • [0071] S200, obtaining a time interval between a current effective peak and an effective peak obtained last time.

[0072] Here, when it is determined that the acceleration data includes effective peaks, the continuity of the acceleration data may be determined according to the time interval between the current effective peak and the effective peak obtained last time. When the time interval between two adjacent effective peaks is greater than the preset interval, it means that the acceleration data is discontinuous data, so the effective peak obtained last time cannot be used to determine the current acceleration data. When the time interval between two adjacent effective peaks is less than or equal to the preset interval, it means that the user is in a state of continuous motion, so the step counting information of the user can be further determined according to the acceleration data.

[0073] The method includes:

• • [0074] S300, when the time interval is greater than a preset interval, obtaining a data area of the effective peaks until a next time interval is greater than the preset interval;

[0075] Here, when the time interval is greater than a preset interval, it means that a current motion state of the user has a lower motion frequency than an ordinary walking state. For example, when the use is jumping or moving irregularly, the time interval of the acceleration data recorded by the step counting device may be greater than the preset interval, and when a time interval obtained when the step counting device detects a next effective peak is greater than the preset interval, it is determined that the data area is data area for step counting.

[0076] The method includes:

• • [0077] S400, when the number of effective peaks within the data area is less than a preset value, determining feature information of the effective peaks within the data area; and

[0078] Here, when the number of effective peaks within the data area is less than the preset value, it means that the number of steps of the user has not reached a default step counting condition of the step counting device, such that the acceleration data corresponding to the number of effective peaks in the data area determined by the step counting device may be determined, and feature information of each of the corresponding effective peaks is determined according to the acceleration data.

[0079] When the number of effective peaks within the data area is greater than or equal to the preset value, it means that the effective peaks in the saved acceleration data of the user have reached the preset value, and steps can be counted in sequence based on the acceleration data according to a normal working mode.

[0080] The method includes:

• • [0081] S500, when the feature information of the effective peaks within the data area satisfies a preset condition, updating step counting data.

[0082] Here, when it is determined that the number of effective peaks within the data area is less than the preset value, it is determined first the feature information of the effective peaks, which corresponds to the acceleration data corresponding to the number of the effective peaks within the data area. Specifically, the feature information includes a characteristic value of the effective peak and a time interval with the effective peak obtained last time. In a specific implementation, the characteristic value of the effective peak is an amplitude of the effective peak. When both the amplitude and the time interval satisfy the preset conditions of the step counting device, the step counting data is updated according to the effective peaks.

[0083] The present disclosure provides a step counting method, the step counting method includes: obtaining acceleration data, the acceleration data including effective peaks; determining a time interval between a current effective peak and an effective peak obtained last time; when the time interval is greater than a preset interval, obtaining a data area of the effective peaks until a next time interval is greater than the preset interval; when the number of effective peaks within the data area is less than a preset value, determining feature information of the effective peaks within the data area; and when the feature information of the effective peaks within the data area satisfies a preset condition, updating step counting data. After the step counting device intermittently obtains the acceleration data, the acceleration data can be assessed, so as to assess the step counting data that does not meet the step counting condition, thereby improving the step counting accuracy of the step counting device, and solving the problem in the prior art that step counting devices cannot record the number of steps when the user moves for a short time, which leads to low step counting accuracy.

[0084] Referring to FIG. 3, after the step 200 in the first embodiment, the method further includes:

• • [0085] S600, when the time interval is less than the preset interval, incrementing the number of consecutive times by one, and switching to a next effective peak.

[0086] Here, when the time interval is less than the preset interval, it means that the user is currently in a state of continuous motion, so a current effective peak can be recorded, and the number of effective peaks in the data area is increased by one. Each time the time interval between one of the effective peaks and the effective peak obtained last time is less than the preset interval, the number of consecutive times is determined to be increased by one. When the time interval is greater than the preset interval, it means that the user has changed from the motion state to a static state, so the number of effective peaks in the data area updated by the step counting device may be determined, and the step counting state of the user in the acceleration data corresponding to the consecutive times is determined.

[0087] Referring to FIG. 4, the step 500 in the first embodiment includes:

• • [0088] S510, when the feature information of the effective peaks within the data area satisfies a preset condition, determining the number of counted steps according to the effective peaks; and
  • [0089] S520, resetting the number of effective peaks in the data area to an initial value, and switching to a next effective peak.

[0090] Here, when the comparison of the effective peaks corresponding to the number of effective peaks in the data area with the preset condition is completed, it means that the acceleration data corresponding to the number of effective peaks in the data area has been processed. Accordingly, the number of effective peaks in the data area is needed to be reset to an initial value, which is convenient for processing the subsequent acceleration data. In a preferred embodiment, after determining the acceleration data associated with the number of effective peaks in the data area, the number of effective peaks in the data area is reset to 0.

[0091] After resetting the number of effective peaks in the data area to the initial value, the step counting device completes the update of the step counting data for the effective peaks corresponding to the number of effective peaks in the data area, and a next effective peak may be switched to, so as to perform step counting processing on the subsequent acceleration data.

[0092] In a specific embodiment, a default step counting starting value of the step counting device is 10, and step counting device may start a step counting operation and update the step counting data when it is detected that the number of steps of the user exceeds 10 steps. When the number of effective peaks detected by the step counting device is 8, which is less than 10, the 8 effective peaks are required to be compared with the preset condition respectively, and when 6 effective peaks among the 8 effective peaks satisfy the condition, step counting data of the step counting device is updated to increase the number of recorded steps by 6.

[0093] Referring to FIG. 5, the step 200 in the first embodiment includes:

• • [0094] S210, determining a characteristic value of a current effective peak and a characteristic time point corresponding to the characteristic value of the current effective peak; and
  • [0095] S220, when the characteristic value satisfies a first preset condition and the characteristic time point satisfies a second preset condition, determining a time interval between a current effective peak and an effective peak obtained last time according to the characteristic time point.

[0096] Here, in order to determine the time interval between two adjacent effective peaks, it is necessary to first determine the characteristic values of the two effective peaks and the characteristic time points corresponding to the characteristic values. Specifically, the first preset condition is a preset threshold, the characteristic values of the two effective peaks are firstly compared with the preset threshold, when the characteristic values of the effective peaks are greater than or equal to the preset threshold, it means that the effective peaks can be used to update the step counting data, and after it is determined that the characteristic values of the effective peaks are greater than or equal to the preset threshold, the time interval between the two effective peaks is determined according to the characteristic time points corresponding to the characteristic values of the effective peaks.

[0097] In a specific embodiment, the acceleration data includes five effective peaks, and when comparing characteristic values of the five effective peaks and the preset threshold, it is determined that the first, the second, the third and the fifth characteristic values are greater than or equal to the preset threshold, and the fourth characteristic value is less than the preset threshold, such that when calculating the time interval, a time interval between the first effective peak and the second effective peak, a time interval between the second effective peak and the third effective peak, and a time interval between the third effective peak and the fifth effective peak are calculated respectively, and a time interval between the third effective peak and the fourth effective peak and a time interval between the fourth effective peak and the fifth effective peak are not calculated.

[0098] Referring to FIG. 6, the step 400 in the first embodiment includes:

• • [0099] S410, when the number of effective peaks within the data area is less than a preset value, determining an amplitude of each effective peak and a time interval between adjacent effective peaks;
  • [0100] S420, determining a first variance based on the amplitude and a second variance based on the time interval;
  • [0101] S430, assessing the first variance and a first sub-preset range and the second variance and a second sub-preset range; and
  • [0102] S440, when the first variance is within the first sub-preset range and the second variance is within the second sub-preset range, updating step counting data according to the number of effective peaks in the data area and switching to a next effective peak, wherein the preset condition includes that the first variance is within the first sub-preset range and the second variance is within the second sub-preset range.

[0103] Here, the feature information includes an amplitude of the current effective peak and a time interval between the current effective peak and the effective peak obtained last time; the preset condition includes a first sub-preset range and a second sub-preset range, after determining the amplitude corresponding to the effective peak and the time interval with the effective peak obtained last time, a first variance of a plurality of the effective peaks is determined, and after determining a second variance according to a plurality of the time intervals, it is determined whether the first variance is within the first sub-preset range and whether the second variance is within the second sub-preset range.

[0104] In a specific embodiment, the acceleration data includes five effective peaks, and the five effective peaks are respectively 0.9316, 1.3542, 0.924, 1.1373, and 0.9559; the time intervals between adjacent two of the five effective peaks respectively have 26, 27, 27, and 29 sample points; the calculated first variance is 0.1858, and the second variance is 1.2583. When the first sub-preset range is 0.4, the second sub-preset range is 2.25, the first variance is less than the first sub-preset range, and the second variance is less than the second sub-preset range. Therefore, the five effective peaks in the acceleration data can all update the step counting data set.

[0105] In an optional implementation, when the effective peak is a first effective peak, the time interval is a time interval between a characteristic time point of the effective peak and a reference time point. Specifically, for the first effective peak in a plurality of the effective peaks, since there is no effective peak before the first effective peak, the characteristic time point of the first effective peak and the reference time point are calculated to determine the time interval between the characteristic time point and the reference time point, so as to facilitate the determination of the first effective peak.

[0106] In an optional implementation, when any one of the first variances is not within the first sub-preset range, it means that the effective peak corresponding to the first variance does not meet the step counting requirement, so a next effective peak is switched to; when any one of the second variances is not within the second sub-preset range, it means that the effective peak corresponding to the second variance does not meet the step counting requirement, so a next effective peak is switched to.

[0107] Referring to FIG. 7, after the step 400 in the first embodiment, the method further includes:

[0108] S470, when the number of effective peaks in the data area is greater than the preset value, performing step counting operation on the acceleration data corresponding to the number of the effective peaks in the data area, and resetting the number of the effective peaks in the data area to the initial value.

[0109] Here, when the number of effective peaks in the data area is greater than the preset value, it means that the step counting device can continue to detect the acceleration data in a normal mode, and update the data according to the acceleration data. After the step counting data is updated by the acceleration data, the number of the effective peaks in the data area is reset to the initial value, so as to facilitate the determination of the subsequent acceleration data.
