Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
FIG. 1A is a flow chart illustrating a method of determining an air pressure value according to an exemplary embodiment; fig. 1B is a view of a mobile terminal displaying an air pressure value according to the embodiment shown in fig. 1A, where the embodiment may be applied to a mobile terminal (e.g., a smart phone, a tablet computer), and a temperature sensor and an air pressure sensor may be disposed on the mobile terminal, as shown in fig. 1A, the air pressure value determining method includes the following steps:
in step 101, when an air pressure detection instruction is received, a first ambient temperature in a current state is determined.
In an embodiment, when a user needs to know the air pressure of a current position, an application program for detecting the air pressure on the mobile terminal may be opened, and the mobile terminal generates an air pressure detection instruction in response to the opening operation, so that the air pressure detection instruction may be received.
In another embodiment, the mobile terminal may determine an ambient temperature currently detected by the temperature sensor, and determine the ambient temperature as a first ambient temperature in a current state.
In step 102, a calibration value corresponding to a first ambient temperature is determined.
A description of how to determine the calibration value corresponding to the first ambient temperature may be found in any of the embodiments shown in fig. 2-4 described below, and will not be described in detail herein.
In step 103, a second air pressure value of the current environment is determined according to the calibration value and the first air pressure value currently acquired by the air pressure sensor.
Because the atmospheric pressure value collected by the atmospheric pressure sensor is not the actual atmospheric pressure value of the current environment due to the influence of the ambient temperature, further calibration is required after the atmospheric pressure sensor collects the atmospheric pressure value, that is, the second atmospheric pressure value determined according to the calibration value and the first atmospheric pressure value is the actual atmospheric pressure value of the current environment. It will be understood by those skilled in the art that the actual air pressure value of the current environment can be determined by related techniques based on the calibration value and the air pressure value currently acquired by the air pressure sensor, and the disclosure will not be described in detail herein.
In an exemplary scenario, as shown in fig. 1B, the first ambient temperature in the current state is-2 ℃, and the barometric pressure value indicated by the barometer pointer is the first barometric pressure value currently acquired by the barometric sensor: 992.5hPa, and by a calibration value corresponding to-2 ℃, the calibrated second air pressure value: 990.5hPa, it can therefore be determined that the actual barometric pressure value for the current environment is 990.5 hPa.
In this embodiment, when receiving the air pressure detection instruction, the mobile terminal may first determine a first ambient temperature in the current state, determine a calibration value corresponding to the first ambient temperature, and then determine a second air pressure value of the current environment according to the determined calibration value and a first air pressure value currently collected by the air pressure sensor. According to the method and the device, the air pressure value acquired by the air pressure sensor is calibrated through the calibration value corresponding to the environment temperature in the current state, the actual air pressure value of the current environment can be obtained, and the accuracy of measuring the air pressure value is improved.
In an embodiment, the step 102 may include:
determining a calibration relation between the first ambient temperature and the calibration value;
and determining a calibration value corresponding to the first environment temperature according to the calibration relation.
In an embodiment, the method may further include:
counting the calibration values corresponding to the set number of second ambient temperatures and each second ambient temperature;
and fitting the second environment temperature and the calibration value corresponding to each second environment temperature to obtain a calibration relational expression.
In an embodiment, the step 102 may further include:
determining a first relation list adopted by the first environment temperature, wherein the first relation list is used for recording the relation between the environment temperature and the calibration value;
and searching the calibration value corresponding to the first environment temperature from the first relation list.
In an embodiment, before the step 102, the method may further include:
determining a current altitude;
the step 102 may further include:
determining a second relation list corresponding to the altitude, wherein the second relation list is used for recording the relation between the ambient temperature and the calibration value under the sea wave height;
and searching the calibration value corresponding to the first environment temperature from the second relation list.
Please refer to the following embodiments for the details of how to determine the air pressure.
Therefore, the method provided by the embodiment of the disclosure can improve the accuracy of the measured air pressure value.
The technical solutions provided by the embodiments of the present disclosure are described below with specific embodiments.
FIG. 2 is a flow chart illustrating another method of determining an air pressure value according to an exemplary embodiment; in this embodiment, an example of determining a calibration value corresponding to the first ambient temperature is described by using the above method provided by the embodiment of the present disclosure, as shown in fig. 2, including the following steps:
in step 201, a calibration relationship between the first ambient temperature and the calibration value is determined.
In an embodiment, the mobile terminal may count the calibration values corresponding to the set number of second ambient temperatures and each second ambient temperature, and then fit the calibration values corresponding to the second ambient temperatures and each second ambient temperature to obtain the calibration relation.
The set number may be set according to practical experience, and those skilled in the art can understand that the set number may be set based on the accuracy of the calibration relation and the processing capability of the mobile terminal. The fitting algorithm may be a least squares fitting method, or may be other fitting algorithms, and the disclosure is not limited herein.
In step 202, a calibration value corresponding to the first ambient temperature is determined according to the calibration relation.
In an exemplary scenario, the calibration relation is k × x + b, and if the first ambient temperature is T, then T corresponds to the calibration value of k × T + b.
In this embodiment, the mobile terminal determines the calibration value corresponding to the first ambient temperature through the calibration relational expression between the first ambient temperature and the calibration value, and since the calibration value corresponding to each ambient temperature can be obtained through the calibration relational expression, the accuracy of the calibration value can be ensured, and the accuracy of the actual air pressure value is further improved.
FIG. 3 is a flow chart illustrating a method of determining an air pressure value according to an exemplary embodiment; in this embodiment, an example of determining a calibration value corresponding to the first ambient temperature is described by using the above method provided by the embodiment of the present disclosure, as shown in fig. 3, the method includes the following steps:
in step 301, a first relationship list for a first ambient temperature is determined, the first relationship list being used to record a relationship between the ambient temperature and a calibration value.
In an embodiment, a first relationship list recording a relationship between the ambient temperature and the calibration value may be configured in advance in the mobile terminal, so that after the first ambient temperature in the current state is determined, the corresponding calibration value may be directly found through the first relationship list. As shown in table 1, an exemplary first relationship list.
| Ambient temperature (. degree. C.) | -25 | -10 | 0 | 10 | 25 |
| Calibration value | A1 | A2 | A3 | A4 | A5 |
TABLE 1
In step 302, a calibration value corresponding to the first ambient temperature is looked up from the first relationship list.
In an embodiment, since the ambient temperatures recorded in the first relationship list are in intervals, in the search process, if the first ambient temperature is within a certain temperature interval range in the first relationship list, the calibration value corresponding to the ambient temperature closest to the first ambient temperature may be determined as the calibration value corresponding to the first ambient temperature; if the first ambient temperature is in the middle of a certain temperature interval, the mean value of the calibration values corresponding to the two end points of the temperature interval can be determined as the calibration value corresponding to the first ambient temperature.
In an exemplary scenario, as shown in Table 1 above, if the first ambient temperature is-20 deg.C, then-20 deg.C is between (-25, -10) and the ambient temperature closest to-20 deg.C is-25 deg.C, so the calibration value A1 corresponding to-25 deg.C may be determined as the calibration value corresponding to-20 deg.C; if the first ambient temperature is 5 ℃, then 5 ℃ is between (0, 10) and in the middle of (0, 10), so the calibration value A3 corresponding to 0 ℃ and the mean 0.5 (A3+ a4) of the calibration value a4 corresponding to 10 ℃ can be determined as the calibration value corresponding to 5 ℃.
In this embodiment, the mobile terminal determines the calibration value corresponding to the first ambient temperature by searching the first relationship list, and since the first relationship list records the correspondence between the ambient temperature and the calibration value, it is not necessary to calculate the calibration value in a time-consuming manner, and therefore the calibration value corresponding to the first ambient temperature can be determined quickly.
FIG. 4 is a flow chart illustrating yet another method of determining an air pressure value in accordance with an exemplary embodiment; in the present embodiment, an example is performed by taking the determination of the calibration value corresponding to the first ambient temperature as an example by using the above method provided by the embodiment of the present disclosure. As shown in fig. 3, the method comprises the following steps:
in step 401, the current sea wave height is determined.
In an embodiment, since the mobile terminal is at different altitudes and the calibration value corresponding to the same ambient temperature is different, the mobile terminal may determine the current altitude before determining the calibration value corresponding to the first ambient temperature.
In another embodiment, the mobile terminal may determine current location information and determine a current altitude based on the current location information.
The current location information may be obtained through a Global Positioning System (GPS) module in the mobile terminal. Then the mobile terminal can acquire the altitude high speed corresponding to the current position information through the network server. For example, the current position information is 40 ° 2 '5 "north latitude, 116 ° 18' 9" east longitude, and the corresponding altitude is 50 meters.
In step 402, a second relationship list corresponding to the altitude is determined, and the second relationship list is used for recording the relationship between the ambient temperature and the calibration value at the sea wave height.
In an embodiment, as described in step 401 above, the calibration values corresponding to the same ambient temperature are different at different altitudes, so the mobile terminal may pre-configure a second relationship list corresponding to each altitude interval for recording the relationship between the ambient temperature and the calibration value at the sea wave altitude interval. For example, in the case where the altitude interval is 0 to 50 meters, the second relationship list is as shown in table 2, and in the case where the altitude is 51 to 100 meters, the second relationship list is as shown in table 3.
| Ambient temperature (. degree. C.) | -25 | -10 | 0 | 10 | 25 |
| Calibration value | A1 | A2 | A3 | A4 | A5 |
TABLE 2
| Ambient temperature (. degree. C.) | -25 | -10 | 0 | 10 | 25 |
| Calibration value | B1 | B2 | B3 | B4 | B5 |
TABLE 3
In step 403, a calibration value corresponding to the first ambient temperature is looked up from the second relationship list.
How to find the calibration value corresponding to the first ambient temperature from the second relationship list can be referred to the above description of step 302, and is not described in detail here.
In this embodiment, since the calibration values corresponding to the same ambient temperature are different at different altitudes, the mobile terminal may first determine the second relationship list corresponding to the current altitude, and then search the calibration value corresponding to the first ambient temperature from the second relationship list, so as to further ensure the accuracy of the calibration value.
