[embodiment]
The present invention mainly discloses a kind of automatic energy-saving method of computer, and more specifically, this computer refers to notebook computer or the panel computer etc. of powering by battery, but is not limited.By method of the present invention, can automatically adjust according to user's demand the consumed power of this computer, reach energy-conservation object, and extend the running time of this computer under battery mode, to make the running time of this computer can meet user's expectation.
Head refers to Fig. 2, is the setting process figure of a preferred embodiment of the present invention.First, this computer need be preset with the consumed power (step S10) of at least two groups, wherein the consumed power of each group is neither identical, and each group consumed power is made up of the usefulness power of at least one main usefulness assembly and the power of some perimeter components respectively.This at least one main usefulness assembly mainly can comprise a CPU (central processing unit) 2 and an image process unit 3 as shown in Figure 4, these some perimeter components can comprise backlight mode 41,3G module 42, LAN (Local Area Network as shown in Figure 4, LAN) module 43, bluetooth module 44 and CD-ROM module 45 etc., but be not limited.
Then, this computer is further set the electric source modes of at least two groups, and allow the electric source modes of this at least two group correspond to respectively the consumed power (step S12) of this at least two group, that is to say, if this computer is set with the electric source modes of N group, just must preset at least consumed power of N group, correspond to respectively the electric source modes of this N group, the rest may be inferred.
More specifically, the electric source modes available energy of this at least two group point, therefore corresponding this at least two groups consumed power also have size divide.For instance, the electric source modes of this at least two group can be set to an efficiency mode and a battery saving mode, for example, for example, and the corresponding consumed power of this efficiency mode (peak power) can be greater than the corresponding consumed power of this battery saving mode (average power).But, the foregoing is only preferred embodiments of the present invention, should be as limit.
In the time that user will carry out energy-conservation setting to this computer, this computer mainly can receive a selection instruction of user's input, by this selection instruction, user can select one of them (step S14) of this at least two groups electric source modes, and this selecteed electric source modes can correspond to a selecteed consumed power simultaneously.For example, in the time that user has selected this above-mentioned efficiency mode, will select corresponding this peak power of this efficiency mode simultaneously.
Then, this computer can further receive user's and set instruction, and wherein this setting instruction can at least comprise the expectation running time that user is required, and the on-off mode of these some perimeter components of this computer (step S16).For instance, user can pass through this setting instruction, setting wishes that the running time of this computer can reach 6 hours, whether set the perimeter components such as this 3G module 42, this LAN module 43, this bluetooth module 44 and this CD-ROM module 45 can automatically be adjusted and close by energy conserving system, and whether the brightness that further, also can set this backlight module 41 can be adjusted by energy conserving system etc. automatically.In this, the on-off mode of these some perimeter components, the energy conserving system that refers to computer inside receives after this setting instruction, can learn whether user allows this energy conserving system can have authority automatically to adjust the on off state of those perimeter components (as automatically transferred to and being closed by unlatching, or transfer unlatching to by closing), further automatically to adjust consumed power in subsequent step.
After this step S16, this computer can be by an inner energy conserving system (figure indicate), according to selecteed this electric source modes and corresponding consumed power thereof, the running whether battery of this computer of automatic decision enough maintains this computer reaches this expectation running time (step S18).In the present embodiment, this energy conserving system can be an application software, is executed among this computer, but is not limited.It is worth mentioning that, this computer also can pass through this energy conserving system, the running time in upper this computer of demonstration of a screen (figure does not indicate) under various electric source modes (as this efficiency mode and this battery saving mode), whereby, user can be with reference to this computer the running time under those electric source modes, coordinate actual required carrying out after comprehensive consideration, further set again this expectation running time, and authorize this energy conserving system the on off state of these part or all of some perimeter component 41-45 is adjusted.
Reach this expectation running time if the battery of this computer enough maintains the running of this computer, this energy conserving system makes this computer directly operate on selected this electric source modes of user (step S20).Moreover, if being not enough to maintain the running of this computer, the battery of this computer reaches this expectation running time, the authority that this energy conserving system is authorized according to user, adjust this selecteed consumed power (being mainly the consumed power that downgrades this computer entirety), so as to making the running time of this computer can meet this expectation running time (step S22).
For instance, if user selects this efficiency mode in this at least two groups electric source modes, and the running time of this computer under corresponding this peak power of this efficiency mode is 5 hours, now, if user's the expectation running time is 4 hours, this energy conserving system just can be complied with this step S20, allows this computer directly operate on this efficiency mode.But, if user's the expectation running time is 6 hours, the adjustment authority of the on off state to those perimeter components that this energy conserving system can be authorized according to user, automatically adjust this peak power and (for example close this 3G module 42, and turn down brightness of this backlight module 41 etc., to reduce power), to make the running time of this computer after adjustment, can meet this expectation running time.
In order to judge whether the running time of this computer can meet this expectation running time, this energy conserving system need first be estimated the execution power of each assembly in this computer, and, then according to battery electric quantity, estimate out the running time of this computer under the corresponding consumed power of various electric source modes.Refer to Fig. 3, for the running time of a preferred embodiment of the present invention estimates process flow diagram.As shown in Figure 3, first, this computer is introduced into one of this energy conserving system and measures the page (step S30), and then, in this measurement page, this energy conserving system is estimated the execution power (step S32) of each assembly in this computer.
More specifically, this energy conserving system is estimated this CPU (central processing unit) (CentralProcessing Unit of this computer, CPU) 2 execution power under different executing states, for example: idle (Idle) state, usefulness running with 50% power (step S340) during with usefulness running with 100%; Estimate the execution power of this image process unit (Graphics Processing Unit, GPU) 3 under different executing states, for example: the power (step S342) when idle state, execution playing program add translator with execution; Estimate the execution power consumption of this backlight module 41 under different executing states, for example: minimum value, power (step S344) with the running of 50% usefulness during with usefulness running with 100%; And, the power (step S346) when the some perimeter component 42-45 that estimate this computer divide other to open and close.
Thus, the numerical value that this energy conserving system just can be estimated according to above-mentioned steps S340-S346, calculates this peak power, this average power and a minimum power (step S36) of this computer.But in the present embodiment, take the consumed power of the Three Estates such as peak power, average power and the minimum power of this computer as example, but the real visual reality of this energy conserving system is required, calculates three kinds of above consumed powers, should not be limited.
In the present embodiment, power when execution power when execution power, this backlight module 41 when execution power, this image process unit 3 when this energy conserving system mainly operates with 100% usefulness with this CPU 2 carried out and added translator operates with 100% usefulness and this some perimeter component 42-45 all open, adds the General Logistics Department as this peak power; Power when execution power when execution power when execution power, this image process unit 3 while running with 50% usefulness with this CPU 2 carried out playing program, this backlight module 41 operate with 50% usefulness and this some perimeter component 42-45 all open, adds the General Logistics Department as this average power; And, take this CPU 2 as idle state, this image process unit 3 is the totalling of idle state, this backlight module 41 power during with minimum value running and this some perimeter component 42-45 Close All, as this minimum power.Wherein, this average power is less than this peak power, and this minimum power is less than this average power and this peak power.
It is worth mentioning that, in this computer, also include the assembly that other needs normality to carry out, for example internal memory or embedded controller (Embodied Controller, EC) etc., this energy conserving system is in the time calculating above-mentioned this peak power, average power and minimum power, need the execution power calculation of the assembly of simultaneously these normalities being carried out interior, then calculate according to the general power that all adds the General Logistics Department running time that battery can maintain.But, the foregoing is only preferred embodiments of the present invention, the different numerical value of the real capable of regulating of this energy conserving system, or add up respectively this peak power, average power and minimum power according to different estimation modes, should, depending on actual required and set, should not be limited with above-mentioned data.
In above-mentioned this step S36, calculate after those consumed powers, this energy conserving system is further obtained the battery electric quantity (step S38) of this computer, and according to battery electric quantity, estimate respectively the running time (step S40) of this computer under this peak power, this average power and this minimum power.It is worth mentioning that, this minimum power is the power minimum that this computer can reach, and therefore, the running time of this computer under this minimum power, is the longest running time that this computer can reach under battery mode.That is to say, user set after this expectation running time, whether this energy conserving system can this expectation running time of automatic decision be greater than the running time of this computer under this minimum power, if this expectation running time is greater than the running time of this computer under this minimum power, represent that this expectation running time can not be reached, therefore this computer can show that an information warning is to inform user, and requires user to reset the rational expectation running time.
Continuous please refer to Fig. 4 and Fig. 5, be respectively the hardware structure figure of a preferred embodiment of the present invention and measure cell schematics.As shown in Figure 4, this computer expert crosses a supply socket 1 (DC jack) and is connected battery (figure does not indicate) with charging line related, and this supply socket 1 is connected to a measurement unit 5, by this measurement unit 5, can learn the electric weight of this battery, and the general power that can supply of the electric weight of this battery that converts according to this.In the present embodiment, borrow the numerical value that provides of this measurement unit 5 indirectly to push away to obtain this battery general power of being supplied, but when actual enforcement, also can learn the general power that this battery is supplied from the battery management chip of inside battery (gauge integratedcircuit), embodiment is not limited with above-mentioned.
As shown in Figure 4, these 5 rear ends, measurement unit can the multiple voltage conversion unit 61-67 of tap, and in the present embodiment, those voltage conversion units 61-67 can be pressure drop unit, for example DC voltage changer (DC/DCConverter), but be not limited.By those different voltage conversion unit 61-67, the voltage that this battery can be provided (can be generally for example 19V, but not as limit), be converted to respectively the applicable magnitude of voltage of each assembly in this computer.Example as shown in Figure 4, can pass through those voltage conversion units 61-67, the voltage transitions that this battery provides respectively becomes the multiple different magnitudes of voltage such as cpu power, GPU power supply, backlight module power supply, 3G modular power source, LAN modular power source, bluetooth module power supply, CD-ROM module power supply, but is not limited with above-mentioned.
It is worth mentioning that, different assemblies may be applicable to identical magnitude of voltage, for example Winchester disk drive (figure does not indicate), this CD-ROM drive 45 and the general voltage applicable to 3V of this 3G module 42, in this situation, those assemblies can be connected to same voltage conversion unit, to use the 3V voltage of this voltage conversion unit output.
As shown in Figure 4, those voltage conversion units 61-67 rear connects respectively one or more assembly, in the present embodiment, comprise aforesaid this CPU 2, this GPU 3, this backlight module 41, this 3G module 42, this LAN module 43, this bluetooth module 44 and this CD-ROM module 45, but be not limited.Wherein, this CPU 2 and this GPU 3 can be considered the main usefulness assembly of this computer inside, and this backlight module 41, this 3G module 42, this LAN module 43, this bluetooth module 44 and this CD-ROM module 45 can be considered the perimeter component of this computer inside.And, between those voltage conversion units 61-67 and those assemblies, be connected respectively this measurement unit 5, so as to, measure unit 5 by those, the power while estimating respectively those main usefulness assemblies 2,3 and those perimeter components 41-45 running.
Consult Fig. 5, in the present embodiment, this measurement unit 5 is mainly example with the parallel circuit of a resistance 51 and a microprocessor (MicroProcessor, μ P) 52, but is not limited.In the time that electric current flows through this resistance 51, can be by analog digital conversion (the Analogy-Digital Convertor on this microprocessor 52, ADC) function is learnt pressure drop, and then learns current value, and by bringing in and obtain magnitude of voltage behind these resistance 51 two ends.Thus, just can learn the respectively execution power of this assembly by the computing formula of W=I*V.But, the foregoing is only a preferred embodiments of the present invention, this measurement unit 5 can be realized by various embodiment in fact, should be as limit.
In this step S18 of above-mentioned Fig. 2, the electric source modes that this energy conserving system is selected according to user, adopts corresponding consumed power, and for instance, if user selects this efficiency mode, this energy conserving system can adopt this corresponding peak power; If user selects this battery saving mode, this energy conserving system can adopt this corresponding average power.If user selects this efficiency mode, and this expectation running time of setting while being less than the running time of this computer under this peak power, can make this computer directly operate under this efficiency mode; And if user selects this battery saving mode, and this expectation running time of setting while being less than the running time of this computer under this average power, can make this computer directly operate under this battery saving mode.
But, if user selects this efficiency mode, and this expectation running time is greater than the running time of this computer under this peak power, or user selects this battery saving mode, and this expectation running time is while being greater than the running time of this computer under this average power, this energy conserving system just need to be adjusted the power of this computer, to make the running time of this computer can meet user's demand.
Consult Fig. 6, for the power of a preferred embodiment of the present invention is adjusted process flow diagram.If user selects this efficiency mode by this selection instruction, and this expectation running time is while being greater than the running time of this computer under this peak power, the adjustment authority of the on off state to those perimeter components 41-45 that this energy conserving system is authorized according to user, carries out the adjustment (step S50) of on off state automatically to those perimeter components 41-45.This energy conserving system, by above-mentioned adjustment, reduces this peak power, and again estimates the running time (step S52) of this computer.For instance, under this efficiency mode, default this CPU 2 operates with 100% usefulness with this GPU 3, this backlight module 41 of this computer operates with 100% usefulness, and these some perimeter component 42-45 all open, if user is in this setting instruction, setting this energy conserving system has the authority of the brightness of automatically adjusting this backlight module 41, and setting this energy conserving system has the authority (be adjusted to and close or open) of the on off state of those perimeter components 42-45 of automatic adjustment member, the brightness that this energy conserving system can downgrade this backlight module 41 according to this authority (, reduce power), and automatic closed portion or these whole some perimeter component 42-45, to reduce this default peak power, and extend the running time under the power of this computer after adjusting.
After this step S52, this energy conserving system judges whether this expectation running time is greater than the running time (step S54) after again estimating, if this expectation running time is still greater than the running time after again estimating, get back to this step S50, continue this backlight module 41 to adjust (as downgraded once again the brightness of this backlight module 41 and/or further closing not yet pent these some perimeter component 42-45) with these some perimeter component 42-45.Otherwise, if this expectation running time is less than the running time after again estimating, represent that this expectation running time can be reached, therefore this energy conserving system can make this computer operate on the setting (step S56) after adjustment.
It is worth mentioning that, in order to possess the efficiency of computer in energy-conservation, therefore, in this efficiency mode, the execution usefulness of those usefulness assemblies (, this CPU 2 and this GPU 3) of default this computer can not be restricted.More specifically, refer to that those usefulness assemblies can adjust and carry out usefulness along with the load of executive routine (Loading) size, and its unit usefulness is the highest can reach 100% operational effectiveness.That is to say, under this efficiency mode, be the restriction that the execution usefulness of default those usefulness assemblies can not be subject to this energy conserving system, therefore under the not confined prerequisite of usefulness, the execution power of those usefulness assemblies cannot limit.Illustrate further, if user selects this efficiency mode, this energy conserving system is being adjusted after the on off state of those perimeter components 41-45 according to this authority, if still cannot meet this expectation running time, just be illustrated under this efficiency mode, this expectation running time cannot be reached (because under efficiency mode, do not limit the usefulness of those usefulness assemblies, so cannot by the adjustment of those usefulness assemblies is reduced to overall power).Now, this energy conserving system can require user to reset controlled this authority of those perimeter components 41-45, allows more perimeter component to be adjusted by this energy conserving system; Or require user to reset this expectation running time; Moreover this energy conserving system can require user to change into and select this battery saving mode (because of under this battery saving mode, allowing this energy conserving system to limit the usefulness of those usefulness assemblies).
As mentioned above, under this efficiency mode, in order to keep the efficiency of this computer, the execution usefulness of those usefulness assemblies cannot be limited, but under this battery saving mode, this energy conserving system, except can automatically adjusting the on off state of those perimeter components 41-45 according to this authority, also can be adjusted the usefulness of those usefulness assemblies in rational scope, under usefulness can confined prerequisite, the execution power of those usefulness assemblies can be controlled effectively.As shown in Figure 6, if user selects this battery saving mode by this selection instruction, and this expectation running time, while being greater than the running time of this computer under this average power, this energy conserving system can sequentially be adjusted (step S58) to those perimeter components 41-45, this GPU 3 and this CPU 2.For instance, this energy conserving system is optionally closed those perimeter components 41-45, downgrades the brightness of this backlight module 41, is downgraded the frequency of this GPU 3 and CPU 2, or this GPU 3 is carried out to the adjustment actions such as frequency elimination with CPU 2.This energy conserving system moves to limit the overall efficiency of this computer by above-mentioned adjustment, and then reduces this default average power, and again estimates the running time (step S60) of this computer.
After this step S60, this energy conserving system judges whether this expectation running time is greater than the running time (step S62) after again estimating, if this expectation running time is still greater than the running time after again estimating, this energy conserving system is got back to this step S58, continues those perimeter components 41-45, this GPU 3 to carry out usefulness adjustment with this CPU 2.Otherwise, if this expectation running time is less than the running time after again estimating, represent that this expectation running time can be reached, therefore this energy conserving system can make this computer operate on the setting (step S56) after adjustment.It is worth mentioning that, under this battery saving mode, this energy conserving system is only carrying out adjusting (for example reducing backlight or stopping device) to all perimeter component 41-45 according to this authority, but still cannot meet this expectation running time time, just can carry out usefulness adjustment to this GPU 3; And, this GPU 3 is being carried out to rational usefulness restriction, but still cannot meet in the situation of this expectation running time, just can further carry out usefulness restriction to this CPU 2.
For instance, this CPU 2 that under this battery saving mode is default this computer operates with 50% usefulness, this GPU 3 carries out playing program, this backlight module 41 operates with 50% usefulness, and these some perimeter component 42-45 all open, if user is in this setting instruction, the brightness of setting this backlight module 41 can be adjusted, these some perimeter component 42-45 of part can be closed, this energy conserving system can first be closed according to this authority some perimeter component 42-45 of this part, and downgrade the brightness of this backlight module 41, to reduce this average power, and then extend the running time under the power of this computer after adjusting.But, if the perimeter component 42-45 that this energy conserving system can be closed according to this authority closes all, and the brightness of this backlight module 41 is downgraded after minimum value, still cannot meet this expectation running time, this energy conserving system can be followed the execution usefulness that limits this GPU3 in the reasonable scope; If reasonably having limited the execution usefulness of this GPU 3 in scope, but running time again estimating still cannot meet this expectation running time time, this energy conserving system just can in the end limit the execution usefulness of this CPU 2.
It is worth mentioning that, if reasonably limited after the execution usefulness of this CPU 2 in scope, the running time that this energy conserving system estimates again still cannot meet this expectation running time, represent that this expectation running time cannot be reached, therefore this energy conserving system can send information warning, and request user resets this expectation running time.
By the present invention, user not only can set and allow this computer operate on (for example this efficiency mode and this power saving module) under which kind of pattern, and setting section or whole those perimeter components 41-45 allow this computer automatically adjust according to this authority voluntarily, and this required expectation running time.Whereby, this computer can calculate automatically by this energy conserving system, with in rational scope, adjusts each assembly of this computer, allows the running time of this computer can meet this expectation running time.Therefore, the present invention not only can provide the pattern of formulation to allow user select, and also can allow user assess according to reality is required, and sets voluntarily the required expectation running time, allows whereby the power save mode of computer have more elasticity.
