[0002] In a wearable device, it is necessary to provide a cumulative climbing value of a user in mountain climbing and the like. A sensor for calculating such a value is a barometer. The height value corresponding to a certain barometer can be calculated using the barometric height formula, and the climbing value of this section can be simply calculated by calculating the height difference corresponding to the initial and end barometric pressures. The cumulative climbing value is obtained by accumulating the climbing values of multiple sections.

[0003] However, in the actual process, the barometer itself has noise. If the relative height difference update threshold is set too small, the static deviation is easily accumulated, resulting in an abnormally large climbing value in a static state. At the same time, in the actual mountain climbing and the like, there are ups and downs. If the relative height difference update threshold is set too large, the climbing in this case is completely ignored. In addition, the initial height needs to be updated to calculate the climbing value in this case. SUMMARY

[0044] Embodiment 1

[0045] Reference Figure 1 For an embodiment of the present application, a cumulative climbing height calculation method is provided, comprising:

[0046] S100: Obtain the height average deviation value △H under static condition;

[0047] Further, the height average deviation value under static condition is obtained, and the step comprises:

[0048] Read the air pressure value in the static period to obtain the height value average H in the static period m And the standard deviation H s ;

[0049] The height average deviation value is three times the standard deviation H s in the static period.

[0050] It should be noted that the barometer reading can be converted to height value using the air pressure-height formula, i.e. H = 44300 * (1-(P / P0)^(1 / 5.256)); In the formula: H is the altitude, P0 is the atmospheric pressure (0℃, 101.325kPa).

[0051] At the same time, in the normal distribution, according to the nature of the standard deviation: the data within 1, 2, 3 standard deviations from the mean accounts for 68.2%, 95.4%, 99.6% respectively, therefore the height average deviation value △H = 3*H s , representing the height offset error of the barometer itself under static condition.

[0052] Preferably, the static period is greater than thirty minutes.

[0053] S200: Obtain the environment air pressure value at the initial motion, to obtain the first height value H0;

[0054] S300: Obtain the real-time air pressure value at a certain time during the motion, to obtain the second height value H1;

[0055] S400: Obtain the real-time difference value dh according to the difference between the first height value and the second height value;

[0056] That is: dh = H1-H0.

[0057] S500: judging by the calculation between the real-time difference dh and the height average deviation value AH and the motion updating threshold, and updating the first height value H0.

[0058] Further, the motion updating threshold includes an ascending updating threshold UR and a descending updating threshold UD.

[0059] Further, the ascending updating threshold UR is 2.5 m, and the descending updating threshold UD is 3 m.

[0060] Further, the step of judging by the calculation between the real-time difference and the height average deviation value and the motion updating threshold, and updating the first height value includes:

[0061] When the real-time difference is greater than or equal to the sum of the height average deviation value and the ascending updating threshold, the real-time difference is accumulated to the climbing value, and the current first height value is updated to the current second height value.

[0062] Further, the step of judging by the calculation between the real-time difference and the height average deviation value and the motion updating threshold, and updating the first height value includes:

[0063] When the real-time difference is less than or equal to the negative of the sum of the height average deviation value and the descending updating threshold, the current first height value is directly updated to the current second height value.

[0064] It should be noted that the purpose of this step is to track and update the effective fluctuation of the height in real time, which is beneficial to calculate the climbing value of the ascending segment in the process of descending and ascending again.

[0065] Further, the step of judging by the calculation between the real-time difference and the height average deviation value and the motion updating threshold includes:

[0066] When the real-time difference is less than the sum of the height average deviation value and the ascending updating threshold,

[0067] or, when the real-time difference is greater than the negative of the sum of the height average deviation value and the descending updating threshold;

[0068] or, after the first height value is updated to the second height value,

[0069] then, the above steps after obtaining the initial environmental air pressure value of the motion are executed in a loop.

[0070] The above is a schematic scheme of the cumulative climbing height calculation method of the embodiment. It should be noted that the technical scheme of the cumulative climbing height calculation device belongs to the same concept as the technical scheme of the cumulative climbing height calculation method described above. The technical scheme of the cumulative climbing height calculation device in the embodiment is not described in detail, and the details can be referred to the description of the technical scheme of the cumulative climbing height calculation method described above.

[0071] The cumulative climbing height calculation device in the embodiment comprises:

[0072] The acquisition module is configured to acquire the height average deviation value in a static condition, acquire the environment air pressure value at the initial stage of the movement to obtain a first height value, and acquire a real-time air pressure value at a certain moment during the movement to obtain a second height value.

[0073] The calculation module is configured to obtain a real-time difference value according to the difference between the first height value and the second height value.

[0074] The judgment and update module is configured to compare and judge through the calculation between the real-time difference value, the height average deviation value, and the movement update threshold, and update the first height value.

[0075] The embodiment further provides a computing device suitable for cumulative climbing height calculation, comprising:

[0076] The memory is configured to store computer executable instructions, and the processor is configured to execute the computer executable instructions to implement the cumulative climbing height calculation method proposed in the above embodiment.

[0077] The embodiment further provides a storage medium having a computer program stored thereon, and the program is executed by the processor to implement the cumulative climbing height calculation method proposed in the above embodiment.

[0080] Embodiment 2

[0081] Referring to Table 1-2, for an embodiment of the present application, a cumulative climbing height calculation method is provided, and in order to verify its beneficial effects, the comparison results of two schemes are provided.

[0082] Table 1 Comparison test of cumulative climbing value under static state

[0083]

[0084]

[0085] From the above Table 1, it can be seen that in the traditional scheme, the cumulative climbing value also appears under static state, and accumulates with time; using the present application, since the static error of the sensor has been considered, the cumulative climbing value is always zero under static state.

[0086] Table 2 Comparison test of cumulative climbing value under static state

[0087] Conventional scheme cumulative climb value Cumulative climb value according to the invention Cumulative climb value Cumulative climb value 940m 1222m

[0088] Table 2 is the data when climbing an altitude of 943m with many ups and downs of mountains, in the traditional scheme, the relative height is generally used to replace the cumulative climbing value, and in the actual situation, the cumulative climbing value contains the ups and downs of the rising section, so the cumulative climbing value calculated by the traditional scheme has a large error. The cumulative climbing value calculated by the present application is closer to the actual cumulative climbing value.

[0089] It should be noted that the above examples are only used to illustrate the technical solutions of the present application but not to limit the present application. Although the present application is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced, without departing from the spirit and scope of the technical solutions of the present application, and all of them should be covered in the scope of the claims of the present application.
