Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
For convenience to the following description, first the technology related to the embodiment of the present invention is illustrated, have
The terminal of low-voltage auto-off function, can be set a voltage threshold, generally, voltage threshold is permissible when dispatching from the factory
It is arranged to 3.5v.During using terminal, the running voltage of battery can be gradually lowered, when the running voltage of battery
When being reduced to predetermined voltage threshold, terminal can automatic shutdown.It should be noted that the running voltage of battery is reduced to predeterminated voltage
Threshold value, the running voltage not representing battery is zero, now, and still some dump energy in battery, generally, remain
Remaining electricity is the 5%-10% of battery Full Charge Capacity.But, these dump energies may be not enough to support that terminal turns back on, because
For when user needs to reuse terminal, if starting normal starting procedure, the battery in terminal being made to produce bigger
Discharge current, cause the voltage of battery in terminal again below or be equal to predetermined voltage threshold, lead to terminal to be shut down again.As
Fruit is not charged to terminal, and user then cannot reuse the application in this terminal all the time or obtain information in this terminal,
Cause the user is greatly inconvenient.
And the discharge current phase in fact, the voltage of battery is not only related to the dump energy of battery, also with battery generation
Close, the load decision of the terminal that the discharge current that battery produces mainly is located by this battery, load is bigger, and this battery produces
Discharge current bigger, bigger with respect to the voltage drop that when the terminal airspace that this battery is located, the voltage of this battery produces.Under
When face lists the terminal airspace that a Battery pack is located, the voltage of battery, the battery voltage in the case of 500ma constant-current discharge
Test data with the relation of battery dump energy.
The voltage 500ma constant-current discharge voltage of battery during battery dump energy terminal airspace
100%--------4.20v--------4.20v
90%---------4.06v---------3.97v
80%---------3.98v---------3.87v
70%---------3.92v---------3.79v
60%---------3.87v---------3.73v
50%---------3.82v---------3.68v
40%---------3.79v---------3.65v
30%---------3.77v---------3.62v
20%---------3.74v---------3.58v
10%---------3.68v---------3.51v
5%----------3.45v----------3.42v
0%----------3.00v----------3.00v
If by above-mentioned test data it is known that terminal is in the state of 500ma constant-current discharge, when voltage drops to
During 3.79v, battery is considered there remains 40% electricity, and in fact, battery there remains 70% electricity, when terminal is located again
In small current holding state, that is, under Light Condition, the voltage of battery can rise to 3.92v, now, corresponding battery dump energy
For 70%, the electricity of the remaining battery of terminal occurs rebound phenomenon.Similarly, if terminal is still in 500ma constant-current discharge
State, and when reaching voltage threshold 3.51v, terminal can automatic shutdown, if but in fact, now terminal be in Light Condition,
The corresponding voltage of battery is 3.68v, and corresponding dump energy is 5-10%, and terminal can work one section in the case of little load
Time, meet the demand of user.
Turn back on the user leading in order to solve terminal no after low battery automatic shutdown it is impossible in the case of low battery
The problem of method using terminal.The embodiment of the present invention proposes a kind of method turning back on, and is applied in terminal, as shown in figure 1,
The method includes:
Step 101, the start-up command of receiving user's input.
Wherein, start-up command can be the operation of user's Touch screen, pressing key or input fingerprint.
The magnitude of voltage of the battery in step 102, detection terminal.
When receiving the start-up command of user input, the magnitude of voltage of battery in detection terminal, to determine the electricity in terminal
Whether pond magnitude of voltage now is enough to support the normal work of terminal.
Step 103, when magnitude of voltage be less than or equal to predetermined voltage threshold when, limit predetermined number cpu (central
Processing unit, central processing unit) core starts and reduces the frequency of cpu to predeterminated frequency, so that the magnitude of voltage of battery
More than predetermined voltage threshold.
Wherein, predetermined voltage threshold is to make terminal start low-voltage auto-off program to protect the electricity of the battery in terminal
Pressure marginal value.When battery voltage value terminal is detected is less than or equal to predetermined voltage threshold, then can determine now terminal
Be in low battery state, now, if still make terminal be in load larger in the case of, the process turning back on can make electricity
Pond produces larger discharge current, so that the magnitude of voltage of battery is under predetermined voltage threshold it is impossible to turn back on it is possible to
The cpu core limiting predetermined number starts and reduces the frequency of cpu to predeterminated frequency (frequency of cpu refers to the clock frequency of cpu), with
Reduce the load of terminal, and then make the battery in terminal produce less discharge current, with reducing energy consumption, make the remaining electricity of battery
Amount turns back on process enough to maintain terminal.
It should be noted that the frequency that the cpu core limiting predetermined number starts and reduce cpu simply reduces to predeterminated frequency
The performance of terminal, but can ensure that terminal is turned back on, make the user in case of emergency can reuse terminal.
And, the cpu core of predetermined number and predeterminated frequency all can according to actual needs and the concrete condition of terminal be entered by user
Row setting.
Step 104, execution power-on operation.
It is understood that after execution step 103, terminal has possessed the ability turning back on.
The method turning back on provided in an embodiment of the present invention, by the start-up command detection terminal of receiving user's input
Battery magnitude of voltage, when magnitude of voltage be less than or equal to predetermined voltage threshold when, limit predetermined number cpu core start and reduce
The frequency of cpu, to predeterminated frequency, so that the magnitude of voltage of battery is more than predetermined voltage threshold, and executes power-on operation, and existing
In technology, the process turning back on can make battery produce bigger discharge current, and the magnitude of voltage making battery is again below default electricity
Pressure threshold value, leads to terminal cannot be started up, so that user cannot in case of emergency using terminal be compared, be in low battery weight in terminal
During new start, the cpu core that can limit predetermined number starts and reduces the frequency of cpu to predeterminated frequency, thus, reduces
The load of terminal, and then make the battery in terminal produce less discharge current, reduce the energy consumption of battery, make the surplus of battery
What remaining electricity be enough to maintain terminal turns back on process.It is in the terminal during turning back on and is equivalent to and enter a simplification
Boot system, in the boot system of this simplification, the battery in terminal will not produce lead to that terminal shuts down again larger and put
Electric current, user can in case of emergency turn back on and using terminal.
If it is understood that the magnitude of voltage battery in terminal is detected is higher than preset voltage value, need not reduce
The load of terminal also can make terminal normal boot-strap, so in another kind implementation provided in an embodiment of the present invention, above-mentioned
After the magnitude of voltage of the battery in step 102, detection terminal, when magnitude of voltage is higher than predetermined voltage threshold, execute power-on operation.
It is understood that now, the dump energy of the battery in terminal is not reduced to predetermined voltage threshold, and terminal is permissible
According to the start-up command start of user, enter normal working condition, to ensure the normal use of terminal.
In order to reduce the loading condition of terminal further it is ensured that user in case of emergency can be with using terminal, in step
103rd, the cpu core limiting predetermined number starts and reduces the frequency of cpu to after predeterminated frequency, can also limit normal further
The startup of the larger load of operating current, based on this, as shown in Fig. 2 step 104, execution power-on operation, comprising: step 1041
To step 1042.
Step 1041, basis are default to start authority startup function hardware.
Wherein, preset startup authority to include: allow to start and No starting, preset and start the function that authority is that permission starts
Hardware is less than the functional hardware of predetermined current for operating current, presets and starts the functional hardware that authority is No starting for work electricity
Stream is more than the functional hardware of predetermined current.
It should be noted that the execution sequence of the embodiment of the present invention not conditioning step 1041 and step 1042, the present invention is real
Apply example to first carry out step 1041, illustrate as a example rear execution step 1042.
It should be noted that terminal be in the Default Value stage or the process that turns back at this before, in user
When terminal is configured, operating current when each hardware normally runs in detection terminal should be distinguished, and determine each respectively
Whether operating current when hardware normally runs is higher than predetermined current, and the default of hardware that operating current is higher than predetermined current is opened
Dynamic priority assignation is No starting, and default startup priority assignation operating current being less than the hardware of predetermined current is to allow to open
Dynamic.
Wherein, hardware can be radio-frequency module, display screen, audio-frequency module, power amplifier.
It should be noted that when the electricity of the battery in terminal is higher than predetermined threshold value, that is, terminal is in normal start stream
When in journey, the default authority that starts still can start for the hardware of No starting.
For example: the electric current producing during the high-definition camera detecting is 800ma, SD shooting when the electric current that produces be 600ma,
When user uses 4g network data service, the electric current of generation is 500ma, when user sees e-book when screen intensity is higher
When, the electric current of generation is 300ma, when user sees e-book when screen intensity is relatively low, the electric current of generation be 150ma it is assumed that
Predetermined current is 500ma, then when voltage battery is detected is less than predetermined voltage threshold it is allowed to the hardware starting is to support to use
The hardware of e-book is watched at family when screen intensity is higher or lower, and the default startup authority of remaining hardware above-mentioned is forbids opening
Dynamic.
1042nd, starting the default authority that starts is the software application allowing to start.
Wherein, software application can be Games Software or video software, address list, memorandum etc..
Larger operating current can be produced during because of Games Software or video software normal work, increase the energy consumption of battery, then
The software application of No starting is the larger softwares of operating current such as game class software.
And the operating current that produces during the software normal work such as address list, memorandum is less, and in case of emergency, user
Need the probability of the software of the standby record important information such as address list, memorandum larger, then allow the software application starting to be memorandum
The software of record class.
It is understood that after low battery automatic shutdown each time, when user needs to reuse terminal immediately, because
User needs use immediately applying and differing, so, terminal can point out user to select, after this turns back on, to use
Family needs to apply using those, based on this, in another kind implementation provided in an embodiment of the present invention, as shown in figure 3, above-mentioned
Step 1041, basis are default to start authority startup function hardware, specifically can be implemented as step 10411, or is embodied as step
10412 to step 10414.
10411st, starting the default authority that starts is the functional hardware allowing to start.
It is understood that because operating current when allowing the functional hardware starting normally to run is less than predetermined current,
So starting the default authority that starts is the functional hardware allowing to start, terminal will not be made again to shut down because electric current is excessive, user
Terminal can be reused and complete user's operation the most urgent, such as: send note, check message registration, address list, check account
Meeting schedule in this etc..
10412nd, hint instructions are exported.
Wherein, hint instructions are used for pointing out user to be to allow to choose the functional hardware starting to need to prohibit from the default authority that starts
The functional hardware only starting.
It should be noted that after low battery automatic shutdown each time, when user needs to reuse terminal immediately, user
Need the application using not necessarily identical, for example: after certain terminal low battery shutdown, user needs to call, another
After terminal low battery shutdown, user needs to check minutes；Then less in order to ensure that terminal load now is in
State, with support user can within the relatively long time using terminal, terminal is defeated with forms such as dialog box or voice messages
Go out hint instructions, point out user to be to allow selection the functional hardware starting to need the function of No starting hard from the default authority that starts
Part.
10413rd, the selection instruction of receiving user's input.
Wherein, selection instruction is used for the functional hardware of the No starting that instruction user is chosen.
10414th, starting the default authority that starts is in the functional hardware allow startup, except the work(of the No starting that user chooses
Functional hardware outside energy hardware.
It should be noted that because the default startup authority of remaining hardware is permission and starts, then prohibiting certain in user
A bit after the startup of unwanted functional hardware, during execution power-on operation, remaining hardware all can start.
Embodiments of the invention the cpu core limiting predetermined number start and reduce the frequency of cpu to predeterminated frequency after,
Also limit the startup of the larger hardware of operating current, software and the application not needed by user, further reduce again
The discharge current that battery in terminal during start produces, more fully make use of the dump energy of battery, to support
User completes most important operation the most urgent, decreases the charging times of battery meanwhile, extends the service life of battery.
