Optionally, the first preset time may be 1 millisecond, 2 millisecond, 3 millisecond, and the like, in order to implement real-time monitoring of the acceleration of the mobile terminal, the first preset time is in the order of milliseconds, and the shorter the first preset time is, the shorter the cycle interval for acquiring the acceleration of the mobile terminal is, the closer the cycle interval is to the specific motion state of the mobile terminal, the more accurate the analysis result is, and the like, which is not limited herein.
S202: analyzing the motion state of the mobile terminal;
in this embodiment, a first preset time is taken as an interval, a first acceleration and a second acceleration of the mobile terminal are obtained, a vector difference between the first acceleration and the second acceleration is obtained, if the vector difference between the first acceleration and the second acceleration is greater than a preset acceleration difference, the mobile terminal is in an abnormal motion state, and if the vector difference between the first acceleration and the second acceleration is not greater than the preset acceleration difference, the mobile terminal is in a normal motion state.
Optionally, the vector difference between the first acceleration and the second acceleration is obtained by taking a three-dimensional coordinate system as a reference system, that is, a vector subtraction operation is performed on the first acceleration and the second acceleration, the preset acceleration difference includes a preset acceleration absolute value difference and a preset acceleration direction difference, after the vector subtraction operation is performed on the first acceleration and the second acceleration, the absolute value of the obtained vector difference is compared with the preset acceleration absolute value difference, and the acceleration direction change of the obtained vector difference is compared with the preset acceleration direction difference (mainly comparing the angle of the change of the acceleration direction), after the vector subtraction operation is performed on the first acceleration and the second acceleration, the absolute value of the obtained vector difference is greater than the preset acceleration absolute value difference and/or the acceleration direction change of the obtained vector difference is greater than the preset acceleration direction difference, for example, the first acceleration is 9m/s, after the first preset time, the acceleration of the mobile terminal is a second acceleration of-6 m/s, the absolute value of the vector difference is 15m/s, which is greater than the preset acceleration absolute value difference, and the acceleration direction change of the first acceleration and the second acceleration is greater than 90 degrees, which is greater than the preset acceleration direction difference, then the mobile terminal is determined to be in an abnormal motion state, otherwise, the mobile terminal is determined to be in a normal motion state.

Judging whether the second absolute value is larger than a preset temperature difference value: if the second absolute value is greater than the preset temperature difference value and the mobile terminal is in a normal motion state, it is indicated that the temperature rise of the mobile terminal is caused by heat generated by the mobile terminal during operation, and therefore a temperature curve at a corresponding temperature needs to be selected as temperature curve information of the mobile terminal, that is, the temperature curve corresponding to the second temperature value is the temperature curve information of the mobile terminal; if the second absolute value is larger than the preset temperature difference value and the mobile terminal is in an abnormal motion state, the abnormal situation such as large-amplitude vibration or falling of the mobile terminal is caused, so that the temperature of the mobile terminal is abnormally increased, and therefore, a temperature curve corresponding to the first temperature value is selected as temperature curve information of the mobile terminal; if the second absolute value does not exceed the preset temperature difference value, the second difference value can be considered as the normal temperature rise of the mobile terminal, and therefore the temperature curves corresponding to the first temperature value and the second temperature value can be both used as the temperature curve information of the mobile terminal.
Of course, as will be understood by those skilled in the art, a plurality of sets of temperature values of the mobile terminal may be obtained at intervals of a third preset time, and are used for analyzing the motion state of the mobile terminal, so as to obtain the temperature curve information of the battery of the mobile terminal, where the more the sets of temperature values of the mobile terminal are obtained, the more accurate the analysis result is, and the present embodiment analyzes the temperature values of the two sets of mobile terminals, which is only an example, and does not limit the sets of temperature values of the mobile terminal obtained in the present embodiment.
Optionally, the third preset time may be 1 millisecond, 2 milliseconds, 3 milliseconds, and the like, in order to implement real-time monitoring of the temperature of the battery of the mobile terminal, the third preset time is in the order of milliseconds, and the shorter the third preset time is, the shorter the cycle interval for acquiring the temperature of the battery of the mobile terminal is, the closer the cycle interval is to the specific temperature change condition of the mobile terminal, the more accurate the analysis result is, and the method is not limited herein.
Optionally, the preset temperature difference may be 1 ℃, 2 ℃, 3 ℃, and the like, and certainly, as understood by those skilled in the art, the preset temperature difference includes but is not limited to the above situations, and the determination of the preset temperature difference needs to reflect that the mobile terminal has abnormal conditions such as large amplitude vibration or drop, and the temperature of the battery of the mobile terminal is abnormally increased, and the preset temperature difference satisfying the above conditions may be the preset temperature difference set forth in this embodiment, and is not limited herein.
