Fig. 1 is a kind of flow chart of energy-saving mode open method shown according to an exemplary embodiment, the energy-saving mode Open method be applied to smart machine in, smart machine said here can be smart mobile phone, tablet computer, smart television, Multimedia player etc..As shown in Figure 1, the energy-saving mode open method includes the following steps.
In a step 101, the current voltage of battery in smart machine is obtained.
In a step 102, if current voltage is less than the first predetermined voltage and battery is in discharge condition, battery is put Electric current is monitored.
In step 103, if monitoring, the discharge current that continuously predetermined sampling obtains is all higher than predetermined current threshold, The energy-saving mode of open system grade chip, the system level chip under energy-saving mode execute power save function.
In conclusion the energy-saving mode open method provided in the embodiment of the present disclosure, by being less than the first predetermined voltage Discharge current be monitored, when the discharge current for monitoring that continuously predetermined sampling obtains is all higher than predetermined current threshold, The energy-saving mode of open system grade chip;Intelligence can be made even lower than preset minimum voltage suddenly by solving cell voltage The problem of energy equipment is shut down suddenly;Reach when preventing cell voltage suddenly even lower than preset minimum voltage, has caused The effect that smart machine shuts down suddenly.
Fig. 2A is a kind of flow chart of the energy-saving mode open method shown according to another exemplary embodiment, the economize on electricity mould Formula open method is applied in smart machine, and smart machine said here can be smart mobile phone, tablet computer, intelligence electricity Depending on, multimedia player etc..As shown in Figure 2 A, which includes the following steps.
In step 201, the current voltage of battery in smart machine is obtained.
The current voltage of battery mentioned here is the current residual electricity of battery in smart machine, and smart machine is in and opens When opening state, cell voltage can be gradually decreased with the time.
In step 202, if current voltage is less than the first predetermined voltage and battery is in discharge condition, battery is put Electric current is monitored.
If smart machine because the remaining capacity of battery is forced to close after exhausting, may accelerate smart machine hardware for a long time Loss, in order to avoid such case a, it is generally the case that predetermined voltage can be arranged in smart machine in manufacturer, when battery electricity After pressure drops to predetermined voltage, smart machine can be automatically closed.Smart machine suddenly falls to predetermined electricity because of voltage in order to prevent Pressure is following to make smart machine shut down suddenly, and first predetermined voltage, the first predetermined voltage can be set in smart machine Higher than scheduled voltage, once the current voltage of battery is less than the first predeterminated voltage in smart machine and battery is in electric discharge shape State is then monitored the discharge current of battery.
In step 203, if monitoring, the discharge current that continuously predetermined sampling obtains is all higher than predetermined current threshold, The energy-saving mode of open system grade chip, the system level chip under energy-saving mode execute power save function.
Under normal conditions, when smart machine opens the larger program of one or more power consumptions, which can be in Busy condition, the current value of the smart machine discharge current and amplitude of variation can be bigger at this time, and are waited for when smart machine is in When machine state, the current value and amplitude of variation of the smart machine discharge current can be smaller, therefore " scheduled current mentioned here Threshold values " is usually arranged as that the current value of busy condition is in standby and be in less than smart machine higher than smart machine.
After smart machine starts to be monitored the discharge current of battery, discharge current is adopted every scheduled duration Sample then starts the current value to sample rate current when monitoring that the current value of present sample electric current is more than predetermined current threshold Number more than predetermined current threshold is counted, i.e., number is added to 1 from initial value 0, current per continuously monitoring later The current value of sample rate current is more than predetermined current threshold, and number adds 1;When monitoring that the current value of present sample electric current is less than or waits In predetermined current threshold, number restores initial value.That is, the current value that number here is the electric current that continuous sampling is arrived is more than in advance The sampling number of constant current threshold value.
When continuous sampling to electric current current value be more than predetermined current threshold sampling number reach predetermined value when, open The energy-saving mode of system level chip, after energy-saving mode unlatching, System on Chip/SoC can carry out a series of economize on electricitys to cell phone intelligent equipment Operation, such as:Smart machine central processor CPU frequency is reduced, smart machine part core cpu is closed, reduces smart machine Background light brightness, shortening screen stand-by time, closing running background program etc., this programme can be to cell phone intelligent to System on Chip/SoC The battery saving mode that equipment is taken does not limit.
Fig. 2 B are referred to, are the schematic diagrames of the continuous discharge current sample result shown in an exemplary embodiment, are such as schemed Shown in 2B (1), Is is predetermined current threshold, if the number that the current value of sample rate current is more than predetermined current threshold is opened when reaching 8 The energy-saving mode of starting system grade chip starts pair when current voltage is in discharge condition less than the first predetermined voltage and battery The discharge current of battery is monitored.When monitoring that the discharge current of T3 moment batteries is more than Is, start to sample rate current The number that current value is more than predetermined current threshold is counted, secondary when detecting that the discharge current of T4 moment batteries is more than Is Number plus 1, when detecting that the discharge current of T5 moment batteries is more than Is, number adds 1 again, and so on, when count value reaches 8, That is the energy-saving mode of T10 moment open systems grade chip.
As shown in Fig. 2 B (2), Is is time of the current value more than predetermined current threshold that predetermined current threshold sets sample rate current The energy-saving mode of open system grade chip when number reaches 8, when current voltage is less than the first predetermined voltage and battery is in electric discharge shape When state, start to be monitored the discharge current of battery.When monitoring that the discharge current of T2 moment batteries is more than Is, start pair The number that the current value of sample rate current is more than predetermined current threshold is counted, when detecting that the discharge current of T6 moment batteries is small When Is, number restores initial value, when monitoring that the discharge current of T7 moment batteries is more than Is, restarts to sample rate current Current value be more than the number of predetermined current threshold and counted, therefore, at the T10 moment, count not up to 8, therefore be not turned on The energy-saving mode of system level chip simultaneously continues to monitor to the discharge current of battery.
In one possible implementation, predetermined if monitoring that discharge current that continuously predetermined sampling obtains is all higher than Current threshold when control system grade chip being needed to enter energy-saving mode, can control universal input/output in smart machine Mouth GPIO exports the first level, and the first level of GPIO outputs can be used for control system grade chip and enter energy-saving mode, saves System level chip under power mode executes power save function.
It should be noted that the first level of GPIO outputs can be one kind in 0 or 1.
In step 204, monitoring system level chip enters the duration of energy-saving mode, and length reached scheduled duration at that time, then controlled System level chip processed restores default mode of operation, and the system level chip under default mode of operation forbids power save function.
After system level chip enters energy-saving mode, the system level chip under energy-saving mode will execute power save function, if The economize on electricity time is not controlled, smart machine will always be in energy-saving mode state, and the intelligence under electricity-saving state is set The standby smooth operation that may influence certain programs, in order to avoid such case is opened after system level chip enters energy-saving mode The duration that record monitoring system grade chip enters energy-saving mode is opened, when the duration of record reaches scheduled duration, then control system grade Chip restores default mode of operation, and the smart machine under operating mode, which executes, restores smart machine central processor CPU frequency Rate opens smart machine part core cpu, restores the brightness of smart machine background light, restoring the operations such as screen stand-by time, and System level chip under operating mode forbids power save function.
In one possible implementation, monitoring system level chip enters the duration of energy-saving mode, and length reached pre- at that time Timing is long, that is, when control system grade chip being needed to revert to default mode of operation, can then control general defeated in smart machine Enter/delivery outlet GPIO output second electrical levels, second electrical level restores default mode of operation for control system grade chip, gives tacit consent to work System level chip under pattern forbids power save function.
It should be noted that when GPIO output the first level be 0 or 1 in it is a kind of when, GPIO output second electrical level Can be another in 0 or 1.
In step 205, if battery is switched to charged state from discharge condition or cell voltage is more than the second predetermined voltage, Then stop being monitored the discharge current of battery, which is more than the first predetermined voltage.
After the system level chip in smart machine enters energy-saving mode, smart machine can show a prompt message, should Prompt message can prompt the current electric quantity of battery in user's smart machine relatively low, and user is reminded to charge immediately.If user It is charged to smart machine when system level chip is under energy-saving mode, then the state of battery can switch from discharge condition For charged state.
In the case where battery is switched to charged state from discharge condition, due to smart machine battery charge rate often Faster than discharge rate, i.e., when charging to the smart machine under busy condition, charged amount is maintaining smart machine just Often while operation, also has extra electricity and store into battery, and storing the extra electricity to battery can be effectively ensured Smart machine continues to run with other programs, therefore, after detecting that battery is switched to charged state from discharge condition, even if currently Smart machine cell voltage is also possible to be less than the first predeterminated voltage, can also be without the discharge current sampling to not carrying out battery Smart machine carries out current sample, or may not need the smart machine sampled to the discharge current for having carried out battery and continue Current sample, therefore smart machine stopping is monitored the discharge current of battery.
In a kind of application scenarios, even if being charged to battery, the voltage of battery still may in initial charge Can be relatively low, at this time still it is necessary to control in a power saving mode system level chip, and when the voltage of battery is more than second in advance When constant voltage (second predetermined voltage is more than the first predetermined voltage), then show that the voltage of battery at this time is unlikely because prominent The larger application program of right unlatching process and the case where cause to shut down suddenly, therefore can stop carrying out the discharge current of battery Monitoring.
In another application scenarios, after Control System of Intelligent grade chip enters energy-saving mode, system can be to intelligence Energy equipment carries out a series of power save function, and the smart machine cell voltage after power save function has small size rising, at this time It may also can detect the case where smart machine cell voltage is higher than the second predetermined voltage, in this case, smart machine Stopping is monitored the discharge current of battery, and in this case, in order to avoid the rising of cell voltage is voltage wave movable property It gives birth to and not virtual voltage rising, the second scheduled voltage here is higher than the first scheduled voltage.
In step 206, whether detection system irrespective of size chip is energy-saving mode.
In step 207, if system level chip is energy-saving mode, control system grade chip restores default mode of operation.
When smart machine detects that system level chip is energy-saving mode, illustrate system level chip be smart machine into Row power save function.When battery is switched to charged state from discharge condition, since the charge rate of smart machine battery is than electric discharge Rate is fast, and charged amount also extra electricity while maintaining smart machine operation is stored into battery, can be effectively ensured Smart machine has sufficient electricity to continue to run with other programs, therefore can restore default mode of operation with control system grade chip; Alternatively, when cell voltage is more than the second predetermined voltage, since current battery level does not open energy-saving mode in system level chip Voltage conditions in, therefore can also control system grade chip restore default mode of operation.
In conclusion the energy-saving mode open method provided in the embodiment of the present disclosure, by being less than the first predetermined voltage Discharge current be monitored, when the discharge current for monitoring that continuously predetermined sampling obtains is all higher than predetermined current threshold, The energy-saving mode of open system grade chip;Intelligence can be made even lower than preset minimum voltage suddenly by solving cell voltage The problem of energy equipment is shut down suddenly;Reach when preventing cell voltage suddenly even lower than preset minimum voltage, has caused The effect that smart machine shuts down suddenly.
In addition, when battery is switched to charged state or cell voltage more than the second predetermined voltage from discharge condition, explanation Charged amount also extra electricity while maintaining smart machine operation is stored into battery, and smart machine can be effectively ensured There is sufficient cell voltage to continue other operation programs or current battery level and does not open energy-saving mode in system level chip It in voltage conditions, can stop being monitored the discharge current of battery at this time, and control system grade chip is restored into acquiescence work Operation mode.
