First embodiment
Shown in Figure 1 is method flow diagram according to the automatically switching power supply state of first embodiment of the invention.Please refer to Fig. 1, at first, in step S101, under electronic installation was in power down mode, system detected the present time and whether arrives wakeup time, and wherein wakeup time is before the execution time.If the present time is the no show wakeup time still, then electronic installation will continue to maintain power down mode, and with when the present time arrives wakeup time, execution in step S103 wakes electronic installation to duty up.For example, the user is set at 14:00 with the execution time in the timer, and wakeup time is set to 13:50.
When the present time arrives wakeup time, enter step S103, electronic installation is switched to duty, with arrival execution time time at present, automatically perform appointed function, for example the mechanism of pre-recording of videocorder.With the wakeup time is 13:50, and when timer turned round to 13:50, timer was the wake-up signal and is sent to power supply unit, makes power supply unit begin to provide power supply to each member of electronic installation, and electronic installation is waken up to duty.
At last, after appointed function is carried out end, shown in step S105, electronic installation is switched to power down mode, save power supply according to this.For example, self-starter can transmit a power saving announcement information to power supply unit after appointed function is carried out end, to suspend the power supply of partial component.
To possess the videocorder of pre-recording function, the user can be in advance in videocorder, the execution time of pre-recording function is set at 14:00, and be 1 hour the service time of pre-recording function, and being set in preceding 5 minutes of execution time wakes videocorder up (also can be electronic installation inner preset) in power down mode, at this moment, wakeup time is 13:55.In view of the above, when videocorder is under the power down mode, and timer just wakes videocorder up (switching) to duty when turning round to 13:55.Then, when timer turns round to 14:00, pre-recording function will automatically perform recording function.After video recording was through 1 hour, constipation bundle recording function.At last, by pre-recording function, videocorder is reverted to original power down mode.
In practical application, (power down mode of present embodiment is the S1-S5 state for example for Advanced Configuration andPower Interface, ACPI) standard, and duty for example is the S0 state according to advanced configuration and power interface.Be example promptly below, further specify the method for automatically switching power supply state with the ACPI standard.
Shown in Figure 2 is the method flow diagram of automatically switching power supply state under the ACPI standard according to first embodiment of the invention.Please refer to Fig. 2, in the present embodiment, suppose Basic Input or Output System (BIOS) (Basic Input Output System, BIOS) the support S1 and the S3 state of electronic installation.At first, in step S201, electronic installation enters S1 or S3 state, to reduce the consumption of power supply.At this, can select S1 state or S3 state by the user, so that electronic installation enters power down mode.
Then, in step S203, before the present time of timer arrives wakeup time, system will detect whether receive the input signal that the user triggers.And input signal is for example pushed the power supply starting signal that power button triggers for the user.If then execution in step S205 switches to electronic installation the S0 state at once, and when timer arrives the execution time, can automatically perform appointed function by self-starter system, and after appointed function is carried out end, electronic installation be continued to maintain under the S0 state; Otherwise if not, then execution in step S207 when the present time arrives wakeup time, wakes electronic installation up to S0 state.When electronic installation wakes up to the S0 state, shown in step S209, when timer arrives the execution time, system will automatically perform appointed function.
With practical application, suppose that wakeup time is 13:55.After user's electronic installation is set to enter power down mode, if the user when 13:00 just by depressing power button, electronic installation will start immediately to S0 state this moment, and need not wait until that 13:55 wakes electronic installation up again.At this moment, because electronic installation is waken up by the user, this measure represents that the user may need to use electronic installation, thereby electronic installation is continued to maintain under the S0 state.Certainly, electronic installation is being waken up to the S0 state, if arrival also can automatically perform appointed function during the execution time.In addition, if before 13:55, electronic installation does not receive any wake-up signal, just can just wake electronic installation up to S0 state when timer arrives 13:55.
After appointed function is finished, shown in step S211, in stand-by period (for example 2 minutes) after appointed function is carried out end, in can detecting from the wakeup time to the stand-by period, whether receive the input signal (being sent) that the user triggers by input-output units such as mouse, keyboards.If the present desire of expression user is used electronic installation, then execution in step S213 maintains electronic installation under the S0 state.If not, then execution in step S215 then switches to electronic installation S1 or S3 state.
For instance, with recording function, after video recording finished, if the user touches keyboard or mouse in from the wakeup time to the stand-by period, the expression user may prepare to use electronic installation, so electronic installation will remain under the S0 state.If surpass 2 minutes stand-by period, electronic installation does not receive input signal, just electronic installation is switched to original S1 or S3 state, its mode of reaching can be by after detecting the execution recording function, design a control program or cooperate the detection mode of timer, can be returned to original power down mode with a hardware.
It should be noted that under different power down modes because the difference of the degree of power supply supply, electronic installation is waken up to the needed time of duty also can be inequality.So, when if power down mode is hibernation-like state (S4 state) or soft-off state (S5 state), electronic installation can waken up to duty (S0 state), switch to again in the armed state (S1 or S3 state) that can wake up fast, reduce expending of power supply according to this.Below promptly describe when electronic installation is in the lower power down mode of power consumption each step of the method for automatically switching power supply state again in detail for an embodiment.
Second embodiment
Shown in Figure 3 is method flow diagram according to the automatically switching power supply state of second embodiment of the invention.Please refer to Fig. 3, at first, in step S301, be under first power down mode at electronic installation, whether system arrives the present time of first detection. electronics in first wakeup time, and wherein first wakeup time is before the execution time.If time no show first wakeup time then maintains electronic installation first power down mode at present, with when the present time arrives first wakeup time, execution in step S303.Described first power down mode is that power consumption is lower, and needs the long period to wake up to duty, for example is hibernation-like state or soft-off state.
In step S303, when the present time arrived first wakeup time, system woke electronic installation to duty up.Because after electronic installation is switched to duty, may be also for some time apart from the execution time, for power saving, in step S305, to one first stand-by period the time, just electronic installation is switched to second power down mode (for example holding state), reach the effect that continues power saving according to this, but still can take into account the demand that enters duty rapidly.
Then, in step S307, when the present time arrived second wakeup time, system woke electronic installation to duty up again, to automatically perform appointed function in time arrival at present during the execution time.Described second wakeup time is between the execution time and first wakeup time, and for example, the execution time is 14:00, and first wakeup time is 13:50, and second wakeup time is 13:55.
At last, after appointed function was carried out end, shown in step S309, system switched to first power down mode with electronic installation, saves power supply according to this.
In practical application, according to the ACPI standard, duty for example is the S0 state, and first power down mode for example is S4 or S5 state, and second power down mode for example is S1 or S3 state.Be example promptly below, further specify the method for automatically switching power supply state with the ACPI standard.
Shown in Figure 4 is the method flow diagram of automatically switching power supply state under the ACPI standard according to second embodiment of the invention.Please refer to Fig. 4, in the present embodiment, suppose that the BIOS of electronic installation supports S1 and S3 state.At first, in step S401, electronic installation enters S4 or S5 state, to reduce the consumption of power supply.
Then, in step S403, before the present time of timer institute timing arrives first wakeup time, system will detect whether receive the input signal that the user triggers, and for example, push the power supply starting signal that power button triggers by the user.If receive the input signal that the user triggers, then execution in step S405 switches to electronic installation the S0 state at once, and when the present time arrives the execution time, automatically perform appointed function, and after appointed function is carried out end, electronic installation is continued to maintain under the S0 state.
If step S403 is not for receiving the input signal that the user triggers, then execution in step S407 when the present time arrives first wakeup time, wakes electronic installation up to S0 state.
Afterwards, in step S409, in first stand-by period (for example 30 seconds), detect whether receive the input signal (being sent) that the user triggers by mouse, keyboard at first wakeup time.For example, in 30 seconds after first wakeup time, system detects whether receive the input signal that the user triggers.If then execution in step S425 can automatically perform appointed function in time arrival at present by self-starter system during the execution time, and after appointed function is carried out end, electronic installation be maintained under the S0 state.
If step S409 is not for to receive the input signal that the user triggers, then execution in step S411 switches to S1 or S3 state with electronic installation.At this, can enter S1 or S3 state by the systemic presupposition decision, also or by the user select, do not limit at this.
Then, step S413 and described step S403 are same or similar, so be not described in detail in this.In step S413, before the present time of timer institute timing arrived second wakeup time from first stand-by period, system still detected whether receive the input signal that the user triggers.If, execution in step S405 then; Otherwise if not, then execution in step S415 when the present time arrives second wakeup time, wakes electronic installation up to S0 state.
Briefly, because electronic installation is when S4 or S5 state wake up to the S1 state, required time is more of a specified duration, therefore, is waking up earlier before the execution time to the S0 state, switches to the S1 or the S3 state that can wake up rapidly again and comes standby.When near the execution time, can wake to S0 state fast up.
Then, in step S417, when the present time arrives the execution time, can automatically perform appointed function by self-starter system.After appointed function is finished, shown in step S419, after appointed function is carried out end, detect from second wakeup time in second stand-by period, whether receive the input signal (being sent) that the user triggers by input-output units such as mouse, keyboards.If the present desire of expression user is used electronic installation, then execution in step S421 maintains electronic installation under the S0 state.If not, then execution in step S423 then switches to electronic installation S4 or S5 state.
In actual applications, with media center version (Media Center Edition, MCE) " electronic programming forms " are example, and the user can preestablish the TV programme of desiring to record, and with the computer system settings TV programme that 14:00 to 16:00 automatic recording is preset in every day.In addition, suppose that computer system is under the S4 state, its first wakeup time decided at the higher level but not officially announced is preceding 10 minutes of execution time, and second wakeup time is preceding 5 minutes of execution time.
In view of the above, arrive 14:00 preceding 10 minutes (being 13:50) in the present time of computer system and just can enter to the S0 state by Auto Power On.After treating that start is finished, enter the S3 state immediately to continue power saving.Then,, wake state up by the S3 state again, begin video recording with wait to S0 in preceding 5 minutes of the execution time (being 13:55).When treating that the present time arrives 14:00, promptly record a video automatically.And after 16:00 video recording finished, computer system was convenient to 16:02 and is got back to previous power supply status (being the S4 state) automatically.
In the middle of described process, if the user presses power button, keyboard, remote controller buttons during 13:50-16:02, or rolling mouse, press mouse button etc., then computer system will judge automatically that the user has the demand of operational computations machine, and with system held in the S0 state.Certainly, when at present the time arrives 14:00, the computer system action of also can recording a video automatically.
In sum, in described embodiment, can when not using, electronic installation enter power down mode, before desire is carried out appointed function, again electronic installation is waken up automatically performing appointed function, and after complete, switch back power down mode, reach less electricity consumption according to this, also make lifetime of system prolong simultaneously.
