Referring to Fig. 1, it is a kind of schematic flow diagram for the method for detecting abnormal power consumption provided in an embodiment of the present invention, should
Method comprises the following steps：
S101, if current time is default detection moment, obtain terminal dump energy and the current time it
History dump energy data of the preceding terminal in the default detection moment.
Using during mobile terminal, different users may have a different use habits, but same user
Terminal usage behavior can have certain regularity, and this causes the dump energy of terminal also to have certain regularity.Such as
In most cases, terminal is in some fixed time (such as daily 12:00) dump energy, does not have notable difference
Trend, both will not continuous rise, also will not continuous decrease, fluctuation also will not often occur.
In specific implementation, the default detection moment among one day is preset, for example, each integral point moment can be set as
Default detection moment, now preset between detection moment at intervals of 1 hour.It should be noted that default detection moment and
Interval between default detection moment can be by user's sets itself, and the present invention does not do specific restriction to this.During default detection
Interval between quarter is shorter, and the accuracy finally judged is higher, therefore in order to more meticulously observe terminal residual electric quantity data
Fluctuation situation, the interval of the dump energy data of acquisition can be sub-divided into minute.
When current time is default detection moment, the current dump energy of terminal is obtained, and before current time
Terminal presets the history dump energy data of detection moment at this.History dump energy data are included in terminal before current time
In the dump energy data that this presets detection moment.For example, it is assumed that default detection moment is 12:00, then history dump energy
Data are included in the same day 12:Before 00, terminal is 12:The dump energy data at 00 this moment.Specifically, it can be the same day
12:In all number of days before 00, terminal is 12:The dump energy data at 00 this moment, or be the same day 12:Before 00
Terminal is 12 in preset number of days:The dump energy data at 00 this moment.
S102, average residual of the terminal in the default detection moment is determined according to the history dump energy data
Electricity and the first difference threshold.
In specific implementation, the history dump energy data for presetting detection moment at this to terminal carry out statistical analysis, it is determined that
Terminal presets the average residual electricity and standard deviation of the history dump energy data of detection moment at this.Standard deviation, which represents, to be gone through
The fluctuation situation of history dump energy data, standard deviation is bigger, illustrates that the fluctuation of history dump energy data is bigger；Standard deviation is got over
It is small, illustrate that the fluctuation of history dump energy data is smaller.
First difference threshold represents that terminal when the dump energy of default detection moment is in normal range (NR), is put down with described
The maximum difference of equal dump energy.In the present embodiment, according to the average residual electricity and standard deviation of history dump energy data
To determine the first difference threshold.For example, when the standard deviation of history dump energy data is smaller, illustrate terminal in default detection
The probability that larger deviation occurs for the dump energy at quarter and average residual electricity is smaller, and now the first difference threshold can take one smaller
Value.When the standard deviation of history dump energy data is larger, illustrate dump energy of the terminal in default detection moment with being averaged
The possibility that larger deviation occurs for dump energy is larger, and now the first difference threshold can take a larger value.
S103, judges whether the dump energy and the absolute value of the difference of average residual electricity are more than first difference
Threshold value.
In specific implementation, the dump energy of comparison terminal and the absolute value and the first difference threshold of the difference of average residual electricity
The size of value, if the absolute value is not more than the first difference threshold, illustrate that the dump energy of terminal falls in the normal of dump energy
In the range of, now judge that the power consumption of the terminal is normal.
In another embodiment, abnormity point is determined by setting bound, by average residual electricity and the first difference
The difference of threshold value be set to lower limit (LCL), by average residual electricity and the first difference threshold and be set to the upper limit (UCL).Refer to figure
5, dump energy-time diagram it is four regions by two horizontal lines of the UCL upper limits and LCL lower limits, then falls within center line both sides
The sample point in two regions be normal point, the area sample fallen within beyond two horizontal lines of UCL and LCL is exactly exceptional value.
S104, if judged result, which is the dump energy and the absolute value of the difference of average residual electricity, is more than described first
Difference threshold, then judge that the power consumption of the terminal is abnormal.
If the absolute value is more than the first difference threshold, illustrate that the dump energy of terminal falls the normal range (NR) in dump energy
In addition, now judge that the power consumption of the terminal is abnormal.
In the present embodiment, the use habit according to user to terminal can be accurate in time by using the method for statistical analysis
Really differentiate whether the power consumption of terminal is abnormal, so as to take counter-measure in time, ensures the cruising time of terminal, avoids
User is absorbed among awkward situation caused by not enough power supply, improves the usage experience of user.
Referring to Fig. 2, it is a kind of exemplary flow of the method for detection exception power consumption that another embodiment of the present invention provides

S201, if current time is default detection moment, obtain terminal dump energy and the current time it
History dump energy data of the preceding terminal in the default detection moment.
Wherein, the terminal is described in the preset number of days before the history dump energy data are the current time
The dump energy data of default detection moment.
Using during mobile terminal, different users may have a different use habits, but same user
Terminal usage behavior can have certain regularity, and this causes the dump energy of terminal also to have certain regularity.Such as
In most cases, terminal is in some fixed time (such as daily 12:00) dump energy, does not have notable difference
Trend, both will not continuous rise, also will not continuous decrease, fluctuation also will not often occur.
In specific implementation, the default detection moment among one day is preset, for example, each integral point moment can be set as
Default detection moment, now preset between detection moment at intervals of 1 hour.It should be noted that default detection moment and
Interval between default detection moment can be by user's sets itself, and the present invention does not do specific restriction to this.
When current time is default detection moment, the current dump energy of terminal is obtained, and before current time
Terminal presets the history dump energy data of detection moment at this.In the present embodiment, history dump energy data decimation is to work as
Terminal presets the dump energy data of detection moment at this in preset number of days before the preceding moment, such as can choose current time
Terminal presets the dump energy data of detection moment at this in 90 days before.Enter by taking a more specifically default detection moment as an example
Row explanation, such as current time are 12：00, the moment is default detection moment, then historical data refers to 90 days in the past often
One day 12：The data acquisition system of dump energy corresponding to 00 is as history dump energy data.
Sample of the data in (such as 90 days) for the previous period at current time as analysis is chosen, can more embody user
In recent service condition, therefore it may be such that the result of judgement is more accurate.
S202, determine that the terminal is in the average of the dump energy data of the default detection moment in the preset number of days
And standard deviation.
In specific implementation, to terminal in the preset number of days before current time terminal preset the residue of detection moment at this
Electric quantity data carries out statistical analysis, determines that terminal terminal in the preset number of days presets the dump energy data of detection moment at this
Mean μ and standard deviation sigma.
S203, using the average as the average residual electricity, and determined according to the average and the standard deviation
Normal distribution and default first probable value determine first difference threshold.
In specific implementation, by terminal, terminal presets the dump energy data of detection moment at this in above-mentioned preset number of days
Average presets the average residual electricity of detection moment as terminal at this.
Fig. 4 is referred to, is fitted to obtain a normal distribution according to the mean μ and standard deviation sigma, can by the normal distribution
The dump energy for presetting detection moment at this to terminal is predicted.Such as the probability that dump energy falls at (μ-σ, μ+σ) is
68.26%th, the probability that dump energy falls at (μ -2 σ, μ+2 σ) is that 95.46% and dump energy fall in the general of (μ -3 σ, μ+3 σ)
Rate is 99.74%.
The normal probability of dump energy is preset in the present embodiment, then further according to the determine the probability dump energy just
Normal scope (midpoint of the scope is average residual electricity μ).
For example, the normal probability of dump energy is being set as 68.26%, as long as now terminal presets detection moment at this
Dump energy fall and think that the dump energy of terminal is normal in the range of (μ-σ, μ+σ), otherwise it is assumed that the dump energy of terminal
It is abnormal.Or the normal probability of dump energy is being set as 95.46%, as long as now terminal presets the surplus of detection moment at this
Remaining electricity falls thinks that the dump energy of terminal is normal in the range of (μ -2 σ, μ+2 σ), otherwise it is assumed that the dump energy of terminal is different
Often.
Afterwards, first difference threshold is determined according to the normal range (NR) of dump energy.Wherein, first difference threshold
Equal to the half of normal range (NR) length.
For example, when if the first probable value is set as 68.26%, the normal range (NR) of dump energy is (μ-σ, μ+σ), and first is poor
It is worth the standard deviation that threshold value is above-mentioned normal distribution；In probability setting 95.46% that dump energy is normal, dump energy is just
Normal scope is twice of the standard deviation that (μ -2 σ, μ+2 σ) first difference threshold is above-mentioned normal distribution.
It should be noted that by the normal probability of dump energy be set as between 68.26% to 95.46% certain without exception
During rate value, a certain value of first difference threshold between the standard deviation sigma and twice of σ of standard deviation 2, the tool of first difference threshold
