Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.
The embodiment of the application provides a method and a device for collecting ephemeris information, a storage medium and a mobile terminal.
Referring to fig. 1, fig. 1 is a schematic flow chart of an ephemeris information collecting method according to an embodiment of the present application, where the ephemeris information collecting method is applied to a mobile terminal, and the mobile terminal is any intelligent electronic device with a mobile communication function, such as a smart phone, a tablet computer, and a smart watch. As shown in fig. 1, the ephemeris information collecting method provided in this embodiment mainly includes steps S101 to S103, which are described as follows:
step S101: when the positioning function of the mobile terminal is not started, if the mobile terminal is detected to be in a preset motion state, determining a motion scene of the mobile terminal.
The terminal positioning function is a function of positioning a terminal by using a GPS positioning technology or a base station positioning technology, wherein the positioning mode based on the GPS positioning technology is to use a GPS positioning module on a mobile phone to send a position signal of the terminal to a positioning background to realize positioning, and the positioning mode based on the base station positioning technology is to use a base station to measure and calculate the distance between the base station and the mobile phone to determine the position of the terminal. However, in the process of using the terminal by the user, the GPS function is not always turned on, which causes that when the user starts the GPS function next time, if the distance is far from the last positioning position, all ephemeris information needs to be downloaded again to complete positioning, which directly causes that the time for first positioning after the GPS positioning function is turned on is too long, which affects the experience of the user.
In some embodiments, before the step "detecting that the mobile terminal is in the preset motion state", the method further includes: acquiring the acceleration and the angular velocity of the mobile terminal; and if the acceleration is greater than the preset acceleration and the angular velocity is greater than the preset angular velocity, determining that the mobile terminal is in a preset motion state.
The preset acceleration and the preset angular velocity are values determined by statistically considering a minimum velocity of the mobile terminal user in the occurrence of motion (e.g., walking, running). Specifically, when the acceleration is greater than the preset acceleration and the preset angular velocity is greater than the preset angular velocity, the mobile terminal may be considered to be in the preset motion state, that is, the position of the mobile terminal may change.
Specifically, the mobile terminal may continuously detect acceleration and angular velocity of the mobile terminal through built-in motion sensors, such as G-sensors and gyroscopes.
In some embodiments, the step of "determining a motion scene of the mobile terminal" may mainly include: acquiring the acceleration and the angular velocity of the mobile terminal; and determining the motion scene of the mobile terminal according to the acceleration and the angular velocity.
Specifically, the motion scene of the mobile terminal can be mainly divided into a walking scene, a running scene and a riding scene, and through statistics, the up-and-down shaking degrees of the mobile terminal in the walking scene, the running scene and the riding scene are different, specifically as follows:
(1) a walking scene: the speed of the mobile terminal is 3-5 km/h, the up-down shaking is 0.1-0.2 m, and the shaking frequency is 1-3 times/second.
(2) A running scene: the speed of the mobile terminal is 5-10 km/h, the up-down shaking is 0.2-0.5 m, and the shaking frequency is 3-6 times/s.
(3) A riding scene: the moving speed is more than 40 km/h, the up-and-down shaking is less than 0.1 m, and the shaking frequency exceeds 10 times/s (calculating the slight shaking of the jolt during the riding).
According to the up-and-down shaking degree of the mobile terminal in different motion scenes and the variation range of the acceleration and the angular speed corresponding to the up-and-down shaking degree, the motion scene of the mobile terminal can be determined, and it needs to be explained that the specific value ranges of the acceleration and the angular speed are not limited due to the fact that the G-sensors of different models and gyroscopes have different accuracies and measurement standards.
Step S102: determining a period of time according to the motion scene.
Specifically, if the position of the terminal is far from the last positioning position when the GPS positioning function is currently started, the GPS system needs to download all the satellite ephemeris information again to perform positioning, so that when the mobile terminal moves, by downloading the real-time ephemeris information before the maximum distance when all the satellite ephemeris information needs to be downloaded again is exceeded, the real-time ephemeris information can be maintained, and the situation that the time for downloading all the satellite ephemeris information is too long, which causes the too long time for first positioning after the GPS positioning function is started is avoided.
Because the speed corresponding to the mobile terminal is different in different motion scenes, the time duration for reaching the maximum distance when all the satellite ephemeris information needs to be downloaded again is different, for example, a period of time corresponding to a walking scene may be 10 minutes, and a period of time corresponding to a riding scene may be 40 minutes. It should be noted that the determined period of time may be less than the time that exceeds the maximum distance when all the satellite ephemeris information needs to be downloaded again in the motion scene, so as to improve the fault tolerance rate, and even if the speed of the mobile terminal in the motion scene is higher than the speed in the statistical data, the situation that the mobile terminal needs to download all the ephemeris information every time will not occur.
In some embodiments, step S102 may generally include:
acquiring a preset time corresponding to a motion scene;
acquiring a current electric quantity value of the mobile terminal;
if the current electric quantity value is smaller than the preset electric quantity value, prolonging the preset time length to a target time length, and determining the target time length as a period of time length;
and if the current electric quantity value is not less than the preset electric quantity value, determining the preset time length as a period of time length.
It is easy to understand that, the process of turning on the GPS system to download the ephemeris information will certainly increase the power consumption of the mobile terminal, and in order to avoid that the power consumption of the mobile terminal is increased by downloading the ephemeris information in the background under the condition of low power, the frequency of turning on the GPS system by the mobile terminal to download the ephemeris information under the condition of low power should be reduced. Specifically, the preset electric quantity value may be a maximum electric quantity value of the mobile terminal in a low electric quantity state, or may be set by a user in a customized manner. When the current electric quantity value of the mobile terminal is not greater than the preset electric quantity value, the mobile terminal can be considered to be in a low-electric-quantity state, so as to avoid the occurrence of a situation that the power consumption of the mobile terminal is increased in the process of downloading the ephemeris information, so that the mobile terminal is shut down and user experience is affected, therefore, the number of times that the mobile terminal opens the GPS system to download the ephemeris information should be reduced, and correspondingly, the time interval for the mobile terminal to open the GPS system each time to download the ephemeris information should be properly increased.
It should be noted that the target time duration is shorter than the time duration that the mobile terminal reaches the farthest distance when all the satellite ephemeris information needs to be downloaded again in the motion scene.
Step S103: and collecting the ephemeris information at intervals by taking the determined period of time as the interval time for collecting the ephemeris information, and storing the ephemeris information in the mobile terminal for the positioning system to read.
In some embodiments, the step of "collecting ephemeris information at intervals with the determined period of time being a period of time between collecting ephemeris information" may mainly include:
recording the duration of the mobile terminal in a continuous preset motion state;
when the duration reaches the interval duration, starting a positioning system and downloading ephemeris information;
after the ephemeris information is downloaded, closing the positioning system, and resetting the duration;
and returning to the step of recording the duration of the mobile terminal in the preset motion state.
Specifically, the determined period of time is a period of time that the mobile terminal is about to reach a maximum distance beyond a time when all satellite ephemeris information needs to be downloaded again, and if the duration of the mobile terminal continuously presetting the motion state reaches the determined period of time, that is, the interval time, it can be considered that the mobile terminal is about to move to the maximum distance when all satellite ephemeris information needs to be downloaded again, at this time, the positioning system is started and the ephemeris information is downloaded, only part of the real-time ephemeris information needs to be downloaded, and all the ephemeris information does not need to be downloaded, so that the downloading time is saved, and the power consumption of the mobile terminal is reduced.
Furthermore, after the ephemeris information is collected, the positioning system is turned off and timing is performed again to collect the next ephemeris information, so that the ephemeris information is collected by starting the positioning system at intervals in the motion continuous state of the mobile terminal, the real-time performance of the ephemeris information can be ensured, the power consumption of the positioning system can be reduced to the maximum extent, and the electric energy of the mobile terminal is saved.
In this embodiment, the step "storing ephemeris information in the mobile terminal" may mainly include: and replacing or updating the last collected ephemeris information with the ephemeris information collected this time.
Specifically, the ephemeris information may be stored in an internal memory of the terminal, and in order to not affect the storage capability of the terminal, in each time of storage, the ephemeris information collected this time may be used to replace or update the ephemeris information collected last time, so as to save the storage space of the terminal.
In this embodiment, in the process of "collecting ephemeris information at intervals by using the determined period of time as an interval time for collecting ephemeris information", if it is detected that the mobile terminal terminates the preset motion state, the collection of ephemeris information is stopped.
As can be seen from the above, the ephemeris information collecting method provided in this embodiment is applied to a mobile terminal, and when a positioning function of the mobile terminal is not started, if it is detected that the mobile terminal is in a preset motion state, a motion scene of the mobile terminal is determined, a period of time is determined according to the motion scene, and then the ephemeris information is collected at intervals with the determined period of time as an interval time for collecting the ephemeris information, and is stored in the mobile terminal for a positioning system to read, so as to maintain real-time property of the ephemeris information.
Referring to fig. 2, fig. 2 is another flow chart of the ephemeris information collection method according to the embodiment of the present application, where the ephemeris information collection method is applied to a mobile terminal, and mainly includes steps S201 to S206, which are described as follows:
s201: when the positioning function of the mobile terminal is not started, if the mobile terminal is detected to be in a preset motion state, determining a motion scene of the mobile terminal.
Specifically, the specific implementation of step S201 can refer to the embodiment of step S101, and is not described herein again.
S202: and determining a period of time according to the motion scene, wherein the determined period of time is used as the interval time for collecting the ephemeris information.
Specifically, since the speeds corresponding to different motion scenes are different, the time that exceeds the maximum distance when all the satellite ephemeris information needs to be downloaded again is different, for example, a period of time corresponding to a walking scene may be 10 minutes, and a period of time corresponding to a riding scene may be 40 minutes. It should be noted that the determined period of time may be less than the time that exceeds the maximum distance when all the satellite ephemeris information needs to be downloaded again in the motion scene, so as to improve the fault tolerance rate, and even if the speed of the mobile terminal in the motion scene is higher than the speed in the statistical data, the situation that the mobile terminal needs to download all the ephemeris information every time will not occur.
S203: and recording the duration of the continuous motion state of the mobile terminal.
The mobile terminal may be in a preset motion state for a short time, for example, the mobile terminal user moves for a short distance, or the mobile terminal may be in a preset motion state for a long time, for example, the mobile terminal user drives for a long distance. Whether the maximum distance for downloading all the satellite ephemeris information again is about to be achieved by the mobile terminal can be judged by recording the duration of the mobile terminal in the continuous preset motion state.
S204: and when the duration reaches the interval duration, starting the positioning system and downloading the ephemeris information.
Specifically, when the duration reaches the interval duration, it can be considered that the distance from the current position of the mobile terminal to the position before the motion of the mobile terminal is the farthest distance when all the satellite ephemeris information needs to be downloaded again, at this time, the positioning system is started and the ephemeris information is downloaded, only part of the real-time ephemeris information needs to be downloaded, and all the ephemeris information does not need to be downloaded, so that the downloading time is saved, and the power consumption of the mobile terminal is reduced.
S205: and after the ephemeris information is downloaded, replacing or updating the last collected ephemeris information with the ephemeris information collected this time.
Specifically, the ephemeris information may be stored in an internal memory of the terminal, and in order to not affect the storage capability of the terminal, in each time of storage, the ephemeris information collected this time may be used to replace or update the ephemeris information collected last time, so as to save the storage space of the terminal.
S206: and (5) closing the positioning system, clearing the duration and returning to the step of S203.
Specifically, after the ephemeris information is collected, the positioning system is turned off and timing is performed again to collect the next ephemeris information, so that the ephemeris information is collected by starting the positioning system at intervals in the motion continuous state of the mobile terminal, the real-time performance of the ephemeris information can be guaranteed, the power consumption of the positioning system can be reduced to the maximum extent, and the electric energy of the mobile terminal is saved.
As can be seen from the above, the ephemeris information collecting method provided in this embodiment is applied to a mobile terminal, and when a positioning function of the mobile terminal is not started, if it is detected that the mobile terminal is in a preset motion state, a motion scene of the mobile terminal is determined, then a period of time is determined according to the motion scene, the determined period of time is an interval time for collecting ephemeris information, and a duration time of a continuous motion state of the mobile terminal is recorded, when the duration time reaches the interval time, a positioning system is started, and ephemeris information is downloaded to maintain real-time property of the ephemeris information, so that when the positioning function is started for positioning, it is not necessary to download all ephemeris information, but only partial real-time information is downloaded, and a time for first positioning after the positioning function is started is shortened, and then, after the ephemeris information is downloaded, the last collected ephemeris information is replaced or updated, the storage method only needs to occupy a little memory and does not affect the storage capacity of the terminal, then the positioning system is closed, the duration is reset, and the step of executing the duration of the continuous motion state of the mobile terminal is returned, so that the power consumption of the GPS system and the power consumption of the mobile terminal can be reduced to the maximum extent.
According to the methods described in the foregoing embodiments, this embodiment will be further described in terms of an ephemeris information collection apparatus, which may be specifically implemented as an independent entity or integrated in a mobile terminal.
