and 106, processing the third air pressure data based on the data processing mode to obtain processed target air pressure data.
In the embodiment of the application, the electronic equipment such as the mobile phone acquires the air pressure data through the built-in air pressure sensor, and the calculation and the measurement of the altitude can be realized through the air pressure data, so that the electronic equipment has the function of measuring the current altitude.
Wherein, for satisfying waterproof dirt-proof needs, electronic equipment such as cell-phone all has good gas tightness generally, between its inner space and the outside, except the balancing hole that is used for balanced inside and outside atmospheric pressure of cell-phone of independent design, other positions all keep sealed, and in order to satisfy waterproof demand, still be provided with waterproof ventilative membrane in the balancing hole.
Because the aperture of the balance hole can not be designed to be large and the ventilation efficiency is limited, when the mobile phone body, such as a screen, a battery cover and the like, is extruded by external force, the screen and the battery cover can deform to a certain extent, so that the space inside the mobile phone is reduced, and the internal air pressure is increased. The reading of the air pressure sensor will then change abruptly.

In the embodiment of the application, the reading change trend of the air pressure sensor is judged based on the first air pressure data, the second air pressure data and the third air pressure data, so that whether the reading data of the air pressure sensor generates sudden change or not is judged.
Specifically, high-pressure air inside the mobile phone can be exhausted to the external environment through the balance hole, fig. 4 shows a schematic diagram of internal air pressure change when the electronic device receives extrusion according to the embodiment of the application, and as shown in fig. 4, in the process that the mobile phone is extruded to balance the internal air pressure and the external air pressure, the internal air pressure of the mobile phone can be suddenly increased and then decreased.
The data _ source is used for expressing the reading of the original air pressure value collected by the air pressure sensor, wherein the first air pressure data _ source n Is the reading of the original air pressure value collected by the air pressure sensor at the current time, namely the first air pressure data, data _ source n-1 And the historical air pressure value reading acquired by the air pressure sensor at the time before the current time is the second air pressure data.
The processed air pressure data, specifically the air pressure data after the influence caused by the sudden change of the air pressure due to the external force extrusion is suppressed, is expressed by data _ dest, so that the air pressure data is closer to the actual air pressure data compared with the original air pressure value reading. Wherein, data _ dest n-1 Is to data _ source n-1 That is, the third air pressure data after the second air pressure data is processed.
According to the first air pressure data _ source n And third air pressure data _ dest n-1 Determines a first value, denoted as date1, i.e. there is date1= data _ source n -data_dest n-1 . The first value date1 is used for measuring the variation of the air pressure in unit time, and whether the air pressure has sudden change can be judged according to the first value.
According to the first air pressure data _ source n And second air pressure data _ source n-1 Determines a second value, denoted as date2, i.e. there is date2= data _ source n -data_source n-1 . The second numerical value date2 is used to measure the trend of the air pressure change, wherein date2 indicates an upward trend of the air pressure when it is an integer, and indicates a downward trend of the air pressure when date2 is a negative number.
Whether sudden change occurs in the air pressure reading and the change trend can be accurately judged based on the comparison results of the first numerical value date1, the second numerical value date2 and the preset first threshold, the data processing mode is determined according to the judgment results, the current air pressure reading is processed, the influence of sudden change of the air pressure on the reading of the air pressure sensor caused by external force extrusion can be inhibited, the problem that the reading of the air pressure sensor is inaccurate is solved, and the measurement accuracy of the altitude of the electronic equipment is improved.

In the embodiment of the present application, based on the first value date1 being greater than the first threshold, it can be determined that the increment of the air pressure reading in the unit time exceeds the set threshold, and it is determined that the read air pressure reading has a sudden change. If the second value date2 is greater than 0 at this time, the air pressure is in a rising state, and at this time, the data processing mode is determined to adopt a linear tracking of the rising of the actual air pressure according to a set first preset variation amount deta _ up, that is, the rising of the air pressure in the current time period is set to deta _ up, specifically, the rising of the air pressure reading is deta _ up in each preset time unit (from the previous time to the current time), so that sudden change of the air pressure is suppressed.
The method specifically comprises the following steps: when the beta 1 is satisfied>a and deta2>0, the processed third air pressure data _ dest n ＝data_dest n-1 +deta_up。
Where a is a first threshold, the first threshold a and the first preset variation amount deta _ up may be empirically set values, and exemplarily, the first threshold may be 2.5m/s and the first preset variation amount may be 1m/s, with the altitude change rate as a unit of the first threshold and the first preset variation amount.
Since the deta _ up is constant, when the deta1 is satisfied>a and deta2>0, the processed third air pressure data _ dest n Is the amount of linear increase in air pressure data relative to the last time instant.
Based on the opposite number of the first numerical value date1 being smaller than the first threshold, it can be determined that the decrement of the air pressure reading per unit time exceeds the set threshold, and it can be determined that the read air pressure reading has a sudden change. If the second value date2 is smaller than 0 at this time, the air pressure is in a descending state, and at this time, the data processing mode is determined to be that the ascending of the actual air pressure is linearly tracked according to the set second preset variation amount deta _ down, that is, the descending amount of the air pressure in the current time period is set to be deta _ down, specifically, the descending amount of the air pressure reading is deta _ down in each preset time unit (from the previous time to the current time), so that the sudden change of the air pressure is inhibited.
The method specifically comprises the following steps: when the amount of deta1 < -a and deta2 are satisfied>0, data _ dest n ＝data_dest n-1 -deta_down。
The second preset variation amount deta _ down may be a value set empirically, and may be 1m/s, for example, with the altitude change rate as a unit of the second preset variation amount.
Since deta _ down is constant, when deta1 < -a and deta2 are satisfied>0, the third air pressure data _ dest after processing n Is the amount of linear decrease relative to the air pressure data at the previous time.

wherein, the third processing mode comprises: processing the third air pressure data according to a first preset function corresponding to the third processing mode so as to enable the target air pressure data to increase in a nonlinear mode based on the first preset function;
the fourth processing mode comprises the following steps: processing the third air pressure data according to a second preset function corresponding to the fourth processing mode so as to enable the target air pressure data to be nonlinearly reduced based on the second preset function;
the first preset function and the second preset function are both curve function first preset functions.
In the embodiment of the present application, based on the first numerical value date1 being greater than the first threshold, it can be determined that the increase amount of the air pressure reading in the unit time exceeds the set threshold, and it is determined that the read air pressure reading has a sudden change. If the second value date2 is less than or equal to 0, the air pressure is in a decreasing state, and in order to prevent the linear tracking from causing excessive increment, a quadratic curve fitting mode of linear tracking rising is adopted to process the air pressure data (the nonlinear tracking is distinguished by the same change amount of each data relative to the linear tracking, and the nonlinear tracking is in a curve shape and is similar to a quadratic function).
The method specifically comprises the following steps:
when the deta1 > a and the deta2 is less than or equal to 0, the data _ dest n ＝data_dest n-1 +Conic_fitting_up；
Wherein, the configured _ fitting _ up is a first preset function, and the first preset function can be a quadratic curve fitting nonlinear ascending function, the first preset function, configured _ fixing _ up, can be empirically set as a three-segment piecewise function, and exemplarily, the first preset function, configured _ fixing _ up, is:
that is, when the absolute value of the deta2 is equal to or greater than 0.16m/s, the value of Conic _ fixing _ up is 0m/s, when the absolute value of the deta2 is less than 0.16m/s and greater than 0.1m/s, the value of Conic _ fixing _ up is 0.1m/s, and when the absolute value of the deta2 is less than 0.1m/s, the value of Conic _ fixing _ up is 0.1m/s.
Since the Conic _ fitting _ up is a fitted curve function, when the deca 1 > a and the deca 2 is less than or equal to 0, the processed third air pressure data _ dest n Is the amount of non-linear increase relative to the barometric pressure data at the previous time.

determining a second preset function according to the absolute value of the second numerical value;
and determining target air pressure data according to the difference between the third air pressure data and the second preset function.
In the embodiment of the present application, based on the opposite number of the first numerical value date1 being smaller than the first threshold, it can be determined that the decrease amount of the air pressure reading in unit time exceeds the set threshold, and it is determined that the read air pressure reading has a sudden change. If the second value date2 is greater than or equal to 0, the air pressure is in an increasing state, and in order to prevent the decrease due to the linear tracking from being excessive, the air pressure data is processed by adopting a quadratic curve fitting mode of linear tracking decrease.
The method specifically comprises the following steps:
when the deta1 is less than-a and the deta2 is more than or equal to 0, the data _ dest n ＝data_dest n-1 -Conic_fitting_down；
Wherein, conic _ fitting _ Down is a first predetermined function, which may be a quadratic curve fitting nonlinear rising function, the first preset function, config _ fixing _ down, may be empirically set as a three-segment piecewise function, and is exemplarily:
that is, when the absolute value of the deta2 is 0.16m/s or more, the value of Conic _ fixing _ Down is 0m/s, when the absolute value of the deta2 is less than 0.16m/s and more than 0.1m/s, the value of Conic _ fixing _ Down is 0.1m/s, and when the absolute value of eta2 is less than 0.1m/s, the value of Conic _ fixing _ Down is 0.1m/s.
Since the Conic _ fitting _ down is a fitted curve function, when the deca 1 is less than-a and the deca 2 is more than or equal to 0, the processed third air pressure data _ dest n Is the amount of non-linear decrease relative to the air pressure data at the previous time.
