Embodiment 1
[0056] figure 1 A flow chart of a method for calculating pitch frequency provided by an embodiment of the present invention is shown, and the method includes:
[0057] Step S110: Obtain the pitch information according to the preset time interval;
[0058]Specifically, the setting of the time interval can be different according to different usage environments, but it should be noted that once the time interval is determined, the later calculation of the step frequency information will be updated based on this.
[0059] Specific ways to obtain cadence information include:
[0060] Get the starting step information step of the above time interval 1 And the end step information step of the above time interval 2 ;
[0061] The step information substep of the step frequency is obtained by subtracting the step information of the start end from the step information of the end end.
[0062] substep=step 2 - step 1
[0063] Take the time interval of 2 seconds as an example, step...
Embodiment 2
[0080] On the basis of Embodiment 1, this embodiment of the present invention provides a step frequency calculation method, which is executed by a processor. The difference from Embodiment 1 is that this embodiment of the present invention also provides a step frequency calculation method. The method of caching the cadence information, such as figure 2 shown. The method includes:
[0081] Step S1311: Compare the above-mentioned pitch information with the above-mentioned value range.
[0082] What needs to be explained here is that before obtaining the latest time interval stride frequency information and judging whether the above stride frequency information is abnormal, it also includes: setting the numerical interval freq of the above stride frequency information; setting the abnormal count threshold error.
[0083] Wherein, the numerical interval of the step frequency information is based on the fastest and slowest step frequency of normal people, usually in seconds, and...
Embodiment 3
[0108] Figure 4 A schematic structural diagram of a pitch calculation device provided by an embodiment of the present invention is shown. The unit includes:
[0109] The pitch information acquisition module 401 is used to obtain the pitch information according to the preset time interval;
[0110] A storage module 402, configured to store the above-mentioned pitch information of the latest n time intervals to the cache, n≥2;
[0111] The information judging module 403 is used to obtain the pitch information of the latest time interval, and judge whether the above-mentioned pitch information is abnormal,
[0112] If not, update the stride information in the above cache according to the order of the above time intervals;
[0113] If so, discard the above step frequency information;
[0114] The computing module 404 is configured to calculate the pitch information in the buffer to obtain the average pitch information.
[0115] The pitch calculation device provided by the em...
