[0026] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, in which the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0027] The weather warning method, device, electronic device and storage medium of the embodiments of the present application are described below with reference to the accompanying drawings.

[0028] Figure 1 A flowchart of a weather warning method provided by an embodiment of the present application is shown in the figure.

[0029] The embodiments of the present disclosure are exemplified by the weather warning method being configured in a weather warning device, which can be applied to any electronic device, so that the electronic device can perform a weather warning function.

[0030] The electronic device can be any device with computing capability, for example, a mobile terminal, a mobile terminal such as a mobile phone, a tablet computer, a personal digital assistant, a wearable device, etc. hardware device with various operating systems, touch screens and / or display screens.

[0031] As shown in the figure, the method can include the following steps: Figure 1

[0032] Step 101, obtaining first air pressure data collected by an electronic device at at least one time and positioning data of the electronic device.

[0033] As an implementation manner, the first air pressure data at each time is collected by an air pressure gauge, and the type of the air pressure gauge is not limited in the present embodiment.

[0034] As an implementation manner, the positioning data of the electronic device at each time is obtained by a global navigation satellite system (GNSS) or a network, a base station, etc. The positioning data can be screened according to signal quality, i.e. the GNSS data is screened according to horizontal dilution of precision and horizontal accuracy, so as to improve the quality of the positioning data. The positioning data includes three-dimensional position (longitude, latitude, height) and time information of the electronic device. The height can be altitude data.​

[0035] It should be understood that the positioning data and the first air pressure data can be filtered to filter out interference signals and improve signal quality.

[0036] In step 102, for each time, target altitude data of the time is determined according to the positioning data and / or the first air pressure data of the time.

[0037] In an implementation of the embodiment of the application, for each of the plurality of times, second standard air pressure data corresponding to a position in the positioning data of the time is obtained, wherein the positioning data of the time includes a position (longitude and latitude) of the electronic device, and the standard air pressure data of a region corresponding to the position where the electronic device is located is obtained through a network where the electronic device is located, and is referred to as second standard air pressure data. Further, the first altitude value of the time is determined according to the first air pressure data and the second standard air pressure data of the time, and the first altitude value of the time is taken as the target altitude data of the time.

[0038] The first altitude value H1 can be determined by the following method:

[0039]

[0040] P1 is the first air pressure data of the time, and P 0_2 is the second standard air pressure data of the time. It should be noted that 5.256 is

[0041] Therefore, the altitude data can be determined according to the first air pressure data of the time. Since the positioning data also includes the altitude data, the altitude data determined based on the air pressure data and the altitude data in the positioning data cooperatively determine the target altitude data of the time, and the accuracy of the determination of the altitude data is improved.

[0042] ​In another implementation manner of the embodiment of the application, the altitude data can be determined according to the first air pressure data of the moment. Since the positioning data also includes the altitude data, in one scenario, if the accuracy of the altitude data determined based on the first air pressure data of the moment is greater than a first threshold, and the accuracy of the altitude data included in the positioning data of the moment is less than a second threshold, wherein the first threshold is greater than the second threshold, that is, if the accuracy of the altitude data determined based on the first air pressure data of the moment is higher, and the accuracy of the altitude data included in the positioning data is lower, the altitude data determined by the first air pressure data of the moment is taken as the target altitude data of the moment. In another scenario, if the accuracy of the altitude data determined based on the first air pressure data of the moment is less than the second threshold, and the accuracy of the altitude data included in the positioning data of the moment is greater than the first threshold, wherein the first threshold is greater than the second threshold, that is, if the accuracy of the altitude data determined based on the first air pressure data of the moment is lower, and the accuracy of the altitude data included in the positioning data is higher, the altitude data in the positioning data of the moment is taken as the target altitude data of the moment, thereby improving the accuracy of the determination of the altitude data.

[0043] In step 103, the abnormal weather warning is performed according to the target altitude data and the first air pressure data of at least one moment.

[0044] In the embodiment of the application, based on the target altitude data of at least one moment, the altitude change condition or trend in the corresponding period can be determined, for example, whether to increase rapidly or decrease rapidly. And based on the at least one first air pressure data, whether the air pressure changes rapidly in the corresponding period can also be determined, for example, the air pressure drops sharply, which usually means that the storm is coming soon. In the embodiment of the application, the possibility of abnormal weather occurrence is judged according to the trend of altitude change and the trend of air pressure change, and part of the movement scenarios can be filtered, for example, the movement scenarios of climbing a mountain or downhill, in which the altitude data will increase or decrease rapidly, and the air pressure data will also change greatly. In these scenarios, the possibility of abnormal weather occurrence is small, and no warning prompt is needed, thereby improving the accuracy of the warning prompt. Wherein, the abnormal weather usually refers to severe weather, for example, storm, blizzard, etc.

[0045] Wherein, at least one moment corresponds to a period of time, for example, half an hour, 1 hour, 2 hours or 4 hours, etc.

[0046] In the weather warning method of the embodiment of the present application, the first air pressure data collected by the electronic device at at least one time and the positioning data of the electronic device are acquired, for each time, the target altitude data of the time is determined according to the positioning data and / or the first air pressure data of the time, and the weather warning is performed according to the target altitude data and the first air pressure data of at least one time. The target altitude data of each time is determined based on the air pressure data and the positioning data, the accuracy of the determination of the altitude data is improved, the misjudgment rate of the abnormal weather warning is reduced based on the at least one target altitude data and / or the at least one first air pressure data, and the accuracy of the warning is improved.

[0047] Based on the above embodiment, Figure 2 The flowchart of another weather warning method provided by the embodiment of the present application is shown in FIG. 2, which comprises the following steps: Figure 2 As shown in FIG. 2, the method comprises the following steps:

[0048] In step 201, the first air pressure data collected by the electronic device at at least one time and the positioning data of the electronic device are acquired.

[0049] In step 201, the first air pressure data collected by the electronic device at at least one time and the positioning data of the electronic device are acquired.

[0050] In step 202, for each time, the second altitude value of the first historical time before the time is acquired.

[0051] The first historical time is any historical time before the time, and as an example, the first historical time is the previous time of the time.

[0052] In step 203, the second altitude value is corrected to determine the target corrected altitude value of the time.

[0053] In the embodiment of the present application, the user will not have a large displacement in a short time, that is, the air pressure data may not have a large change, and there is a problem of low accuracy in directly calculating the altitude data according to the air pressure data. In the embodiment of the present application, the historical determined altitude data is corrected to determine the altitude data of the current time. Since the correction is made on the historical altitude data, the accuracy is improved. Therefore, for each time, the altitude value of the previous historical time is corrected to improve the accuracy. The following two correction methods are used for illustration:

[0054] As an implementation manner, the second air pressure data collected at the first historical moment is acquired, and a first altitude correction value is determined according to a difference between the first air pressure data and the second air pressure data and a set first mapping relationship, wherein the first mapping relationship includes a mapping relationship between the difference of each measured air pressure data and the altitude correction value, and is set based on an experience value. Further, the second altitude value is corrected according to the first altitude correction value to obtain a first corrected altitude value, that is, the first altitude correction value and the second altitude value are superimposed to obtain the first corrected altitude value, and the target corrected altitude value is determined according to the first corrected altitude value. As an implementation manner, the first corrected altitude value is taken as the target corrected altitude value.

[0055] As another implementation manner, an area where the electronic device is located is determined according to the position in the positioning data at the first historical moment, the size of the area can be set based on the requirement of accuracy, the first standard air pressure data of the area corresponding to the position is acquired through the network, and the second standard air pressure data corresponding to the position is acquired according to the position in the positioning data at the moment. A second altitude correction value is determined according to a difference between the first standard air pressure data and the second standard air pressure data and a set second mapping relationship, wherein the second mapping relationship includes a mapping relationship between the difference of each standard air pressure data and the altitude correction value, and is set based on an experience value. Further, the second altitude value is corrected according to the second altitude correction value to obtain a second corrected altitude value, and the target corrected altitude value is determined according to the second corrected altitude value. As an implementation manner, the second corrected altitude value is taken as the target corrected altitude value.

[0056] The second air pressure data can be determined according to the calculation method of the first air pressure data, which will not be described here. It should be noted that the first air pressure data, the second air pressure data, and the third air pressure data and the fourth air pressure data in the subsequent steps are used to identify different air pressure data.

[0057] In step 204, the target altitude value at the moment is determined according to the target corrected altitude value at the moment and the altitude value in the positioning data at the moment.

[0058] In the embodiment of the application, two altitude values are determined at the same moment, that is, the target corrected altitude value based on the air pressure data and the altitude value in the positioning data, and the target corrected altitude value based on the air pressure data and the altitude value in the positioning data are compared to determine whether the accuracy of the target corrected altitude value based on the air pressure data meets the requirement. If it meets the requirement, the target altitude value at the moment is determined according to the target corrected altitude value at the moment, otherwise, the barometer needs to be calibrated and the air pressure data is measured again, and the altitude value is determined according to the air pressure data measured again, and the target altitude value at the moment is determined according to the re-determined altitude value.

[0059] At step 205, the abnormal weather warning is determined according to the target altitude data at the at least one time and the first air pressure data at the at least one time.

[0060] In an implementation form of the embodiment, the at least one time includes a plurality of times, and the altitude difference between the first time and the last time in the plurality of times is determined according to the target altitude data at the plurality of times, so that the altitude change amount in the time period between the first time and the last time can be determined, i.e., the altitude difference, which indicates the altitude change trend. If the altitude difference is greater than the altitude change threshold, it is considered that the user has a large position movement, for example, the user climbs a mountain or reaches a lower place from a high place, resulting in a large altitude change trend. In the case of a large altitude difference, the air pressure usually also changes greatly, but such change usually does not lead to severe weather. Therefore, in the present application, the case of large air pressure change caused by position movement needs to be filtered out. Thus, the altitude difference is compared with the altitude change threshold, and in response to the altitude difference being less than the altitude change threshold, the air pressure difference between the first time and the last time in the plurality of times is determined according to the first air pressure data at the plurality of times, the warning prompt information of the abnormal weather is determined according to the air pressure difference, and the electronic device is controlled to display the warning prompt information. As an implementation form, the corresponding relationship is obtained, wherein the corresponding relationship includes the air pressure difference and the corresponding relationship of the abnormal weather, the corresponding relationship is queried, the abnormal weather corresponding to the air pressure difference is determined, the warning prompt information of the abnormal weather is generated, and the electronic device is controlled to display the warning prompt information.

[0061] As another implementation form, the air pressure difference is compared with the set air pressure change threshold, and in response to the air pressure difference being greater than the set air pressure change threshold, the warning prompt information of the abnormal weather is determined. For example, the air pressure difference is the air pressure difference in 2 hours, the air pressure difference is 500 Pa, and the set air pressure change threshold is 400 Pa. Since the measured air pressure difference 500 Pa is greater than 400 Pa, it is determined that there is a possibility of a storm, and the warning prompt information of the storm is generated and displayed on the interactive interface of the electronic device to remind the user using the electronic device that the abnormal weather may occur and needs to be transferred to a safe area as soon as possible to improve safety.

[0062] In the embodiment, since the air pressure change caused by the user carrying the electronic device to climb high or downhill does not lead to the occurrence of abnormal severe weather, such a scenario needs to be excluded, so that in the case where the altitude difference is less than the altitude change threshold, it is determined that the air pressure change of the electronic device is not caused by the user climbing high (such as climbing a mountain) or downhill, thereby improving the accuracy of the abnormal weather determination and reducing the misjudgment rate.

[0063] In the weather warning method of the embodiments of the present application, the first air pressure data collected by the electronic device at at least one time and the positioning data of the electronic device are acquired, for each time, the target altitude data of the time is determined according to the positioning data and / or the first air pressure data of the time, and the weather warning is performed according to the target altitude data and the first air pressure data of at least one time. The target altitude data of each time is determined based on the air pressure data and the positioning data, which improves the accuracy of the determination of the altitude data. The abnormal weather warning is performed based on at least one target altitude data and / or at least one first air pressure data, which reduces the misjudgment rate of the abnormal weather warning and improves the accuracy of the warning.

[0064] Based on the above embodiments, Figure 3 The flowchart of another weather warning method provided by the embodiments of the present application is shown in FIG. 4, which includes the following steps: Figure 3

[0065] In step 301, the first air pressure data collected by the electronic device at at least one time and the positioning data of the electronic device are acquired.

[0066] In step 302, for each time, the second altitude value of the first historical time before the time is acquired.

[0067] In step 303, the second altitude value is corrected to determine the target corrected altitude value of the time.

[0068] In steps 301 to 303, the related explanations and descriptions in the foregoing embodiments can be referred to, and the principles are the same, which will not be described here again.

[0069] In step 304, the altitude change rate is determined according to the target corrected altitude value of the time and the altitude value in the positioning data of the time, and the altitude change rate is compared with the set change rate threshold.

[0070] As an implementation manner, the target corrected altitude value of the time is H1, and the altitude value in the positioning data of the time is H2, then the altitude change rate ΔH = |H1-H2| / H1 is determined, and the altitude change rate ΔH is compared with the set change rate threshold to determine the change of the target corrected altitude value of the time relative to the altitude value in the positioning data of the time. For example, the set altitude change rate threshold is 0.8.

[0071] In step 305, the target corrected altitude value is taken as the target altitude value in response to the altitude change rate being less than or equal to the change rate threshold.

[0072] ​In the embodiment of the present application, if the target corrected altitude value obtained based on the air pressure data and the altitude value in the positioning data are relatively small, that is, the altitude change rate is less than or equal to the change rate threshold, it is considered that the target corrected altitude value obtained based on the air pressure data has higher accuracy, and calibration of the air pressure gauge for collecting the at least one first air pressure data is not needed, that is, the target corrected altitude value is taken as the target altitude value.

[0073] In step 306, in response to the altitude change rate being greater than the change rate threshold, calibration of the air pressure gauge for collecting the at least one first air pressure data is performed.

[0074] In the embodiment of the present application, if the target corrected altitude value obtained based on the air pressure data and the altitude value in the positioning data are relatively large, that is, the altitude change rate is greater than the change rate threshold, it is considered that the target corrected altitude value obtained based on the air pressure data has lower accuracy, and calibration of the air pressure gauge for collecting the at least one first air pressure data is needed to improve the accuracy of the air pressure gauge, wherein the calibration method can adopt any calibration method in the prior art, and the embodiment is not limited.

[0075] In step 307, the third air pressure data collected by the calibrated air pressure gauge and the second standard air pressure data at the moment are obtained.

[0076] In step 308, the third altitude value is determined according to the third air pressure data and the second standard air pressure data, and the third altitude value is taken as the target altitude value at the moment.

[0077] In the embodiment of the present application, the third air pressure data is re-collected by the calibrated air pressure gauge, and the second standard air pressure data at the moment is obtained, and the third altitude value at the moment is re-calculated, and the re-calculated third altitude value is taken as the target altitude value, the third altitude value at the moment is re-determined by calibrating the air pressure gauge, and the third altitude value at the moment is taken as the target altitude value at the moment, and the accuracy of the target altitude value determination is improved.

[0078] As an implementation manner, the third altitude value is calculated according to the altitude calculation formula in step 102, which is not repeated here.

[0079] As another implementation manner, the third altitude value is determined by the above steps 201 to 203, that is, the third altitude value is a correction result relative to the historical data, so as to improve the accuracy, and the specific implementation manner is not repeated here.

[0080] In step 309, abnormal weather warning is performed according to the target altitude data at the at least one moment and the first air pressure data.

[0081] In step 309, the related explanation and description in the foregoing embodiments can be referred to, and the principle is the same, which is not repeated here.

[0082] In the weather warning method of the embodiment, the first air pressure data collected by the electronic device at at least one time and the positioning data of the electronic device are acquired, for each time, target altitude data of the time is determined according to the positioning data and the first air pressure data of the time, and abnormal weather warning is performed according to the target altitude data and the first air pressure data of the at least one time. The target altitude data of each time is determined based on the air pressure data and the positioning data, which improves the accuracy of the determination of the altitude data. The abnormal weather warning is performed based on the at least one target altitude data and the at least one first air pressure data, which reduces the misjudgment rate of the abnormal weather warning and improves the accuracy of the warning.

[0083] Based on the above embodiment, in the embodiment, if the positioning data cannot be acquired, the altitude data of the corresponding time is directly calculated according to the air pressure data collected by the barometer in the case that the network signal is poor or the positioning module is abnormal. If the positioning data cannot be acquired and the air pressure data also cannot be acquired, the output of the barometer and the altitude data of the last time are maintained, so as to avoid that the electronic device cannot display the air pressure data and / or the altitude data collected at the current time and cannot perform the abnormal weather warning according to the air pressure data and the altitude data collected at the current time.
