Abstract
The invention relates to a power supply management method for a mobile device. A power supply management function only obtained by the mobile device hardware and an operating system is applied to an application software level and enters a dormant state through the application software in a manual or automatic manner, and all application executing programs are stopped and a screen is closed, so that the operation treatment and the screen power consumption of a central processing unit are reduced and effective power supply management can be made.
Description
Technical field
The present invention relates to the method for managing power supply of a kind of method for managing power supply, particularly a kind of mobile device.
Background technology
Although big again by present mobile device battery capacity, its stand-by time and service time are still unsatisfactory, mainly are that the growth of battery capacity fails to catch up with the step of changes of function all the time because the mobile device function is integrated to grow with each passing day.So mobile device manufacturer and operating system (operating system) manufacturer are devoted to the electricity saving method of mobile device invariably, in the hope of improving mobile device service time, and the effective electricity saving method that reduces the mobile device power consumption is to comprise good power management and promote two aspects of process technique (belonging to hardware partly owing to promote process technique, so not at the row of the present invention's discussion).
When general mobile device uses, there is time of 90% to be in standby mode (sleep mode) approximately; But still to show date on the screen, time, battery electric quantity, reception state, and this moment standby mode power consumption need whole screen support to show, so screen becomes mobile device power consumption greatest problem.Mobile device is to use TFT LCD as display mostly at present, and LCD belongs to passive demonstration, and backlight competence exertion display effect need be arranged, and backlight design is regulated drive current to change brightness in addition except that there being out (on) to close (off).And except screen is the power supply power consumption main cause, another one power consumption source promptly be radio frequency (Radio Frequency) block partly, central again with the power amplifier consumed power in the radio frequency spare part for.During mobile device (as mobile phone) is sought base station, conversation, network connections all is the radio frequency block the strongest time of consumed power.Also is one of power supply power consumption source as for other as mobile device message function (for example incoming ring tone, keypad tone, music are dialled and put), CPU (central processing unit) computing, interfacing equipment I/O (I/O).
Therefore; common mobile device method for managing power supply comprises adjusts screen brightness (backlight intensity of LCD); close screen protection (screen saver) function; the shut-in time Presentation Function; avoid using the animation tablecloth; the screen auto sleep; close infrared ray and link function; close blue bud (Bluetooth) function; close wireless network (Wi-Fi) function; close GPRS (General Purpose Radio Service integrates packet radio) function of surfing the Net; close keypad tone; turn down volume; close vibration function; close GPS (GPS) ... or the like allow the setting that the user can select voluntarily or system automatically performs.
And because mobile device hardware and operating system thereof provide the setting and the method for multinomial minimizing power supply power consumption, so general mobile device application software aspect does not just reduce power supply power consumption and does planning more, financial tape reading software for example.With regard to the mobile device financial tape reading software, its power consumption is partly main to be screen (handling the financial tape reading software picture shows), radio frequency block (processing network on-line), CPU (central processing unit) (deal with data computing), input media (as keyboard and Touch Screen).Common mobile device financial tape reading software is only partly done power management planning with regard to the radio frequency block, promptly can automatically network on-line not cut off when the user uses software idle (idle) a period of time (for example 3 minutes), and this moment, the power supply power consumption of radio frequency block promptly can reduce; Or when need not re-using financial tape reading software, the user can close software voluntarily, the power supply power consumption that is the reduction of radio frequency block at this moment.
The power supply power consumption of financial tape reading software aspect screen then is the power management that relies on mobile operating system, is two kinds of branch: 1. application software is left unused, and the screen operator system promptly enters operating system park mode (closing screen) automatically after a period of time; 2. the user can select screen to enter operating system park mode (closing screen) voluntarily.
The 1st kind again in two kinds of situation: a. screen is closed the back financial tape reading software still can continue running, and network is still online and receive data, and its process flow diagram is shown in Figure 1A; B. financial tape reading software promptly suspended running after screen was closed, and network also breaks and stops to receive data, and its process flow diagram is shown in Figure 1B.
The 2nd kind is detected on PDA (as the Windows Mobile PDA of Microsoft), the stock handset, because the shortcut (Microsoft's its power key of Windows Mobile PDA promptly has the function of closing screen concurrently) that this type of mobile device has the screen backlight of cutting out, the user presses and closes still normal operation of application software behind the screen shortcut, network keeps online and receives data, and its process flow diagram as shown in Figure 3.
See also Figure 1A, Figure 1A is common mobile device financial tape reading software still continues running after the operating system auto sleep a process flow diagram.The S1 person of being to use brings into use the mobile device financial tape reading software; S2 is the mobile device screen opening, and wait for that the button Thread promptly starts working this moment; S3 is that the picture that screen presents financial tape reading software is responsible for by the frame updating Thread; S4 sets up network on-line by the network on-line Thread; Treat that online back S5 data transmission Thread promptly begins to be responsible for receiving data, and be responsible for data processing by the data processing Thread; S6 frame updating Thread is the data of frame update with display update after the reception data; Then the S7 person of being to use operation and application software (for example change financial products, inquire about detailed quotation, inquire about real-time line chart ... etc.); S8 operating system auto sleep Thread judges whether idle (idle) time surpass the operating system setting-up time, for example: be made as standby time 3 minutes, if the user surpass 3 minutes not operating moving device be that S9 operating system is closed screen; Then return S5 continuation reception data if surpass setting-up time standby time; S10 waits for that the button Thread imports button with the user and transfer to application software and judge whether the user touches by waking key up after S9 closes screen, if being S13 unlatching screen, "Yes" then returns S5 continuation reception data, if "No" then S11 application software continues to receive data and S12 frame update, follow back S10 operating system and judge that whether the user is by waking key up.
The application Thread (work thread) of application software when S11 receives data includes network on-line Thread, data transmission Thread, data processing Thread, waits for the button Thread, these Threads can continue to use the calculation resources of CPU (central processing unit), and meaning is that CPU (central processing unit) still has power supply power consumption.Though the S12 frame update is in the flow process after S9 closes screen, but financial tape reading software is for upgrading the data after S11 receives, still can frame update, just screen can't show, this is the work of frame updating Thread, frame update is to utilize repaint program (method) in Java language, then be to utilize the onpaint program in Microsoft.Net, though being the user, meaning can't on the mobile device screen, check the S12 frame update of (screen is closed) in the dormancy, but CPU (central processing unit) still continues computing this moment, continue to consume power supply, can't do effective power management.
This kind dormancy function mode operating system when entering park mode and need reach setting-up time standby time can start automatically, and the user only utilizes the mobile device financial tape reading software to do a request for quote apace usually, be not long-time utilization and continual operation, therefore arrive the standby time of reducing power supply power consumption immediately and needless to say setting if will finish at user's data query, unique method is to close financial tape reading software, but need go through software when the user desires once more data query carries out, network on-line, login account ... etc. step, to frequent needs Query Information repeatedly, and each of short duration user of query time, can save power supply power consumption though close financial tape reading software after the inquiry immediately, the real inconvenience that belongs to is gone up in operation.
See also Figure 1B, Figure 1B is the common mobile device financial tape reading software process flow diagram that software promptly decommissions after the operating system auto sleep.The S20 person of being to use brings into use the mobile device financial tape reading software; S21 is the mobile device screen opening, and wait for that the button Thread promptly starts working this moment; S22 is that the picture that screen presents financial tape reading software is responsible for by the frame updating Thread; Then S23 sets up network on-line by the network on-line Thread; Treat that online back S24 data transmission Thread promptly begins to be responsible for receiving data, and be responsible for data processing by the data processing Thread; S25 frame updating Thread is the data of frame update with display update after the reception data; Then the S26 person of being to use function software (for example change financial products, inquire about detailed quotation, inquire about real-time line chart ... etc.); S27 system auto sleep Thread judges whether idle (idle) time surpasses the operating system setting-up time, for example be made as standby time 3 minutes, if the user surpass 3 minutes not operating moving device be that S28 operating system is closed screen, then return S24 and continue to receive data if surpass setting-up time standby time; S28 operating system is closed behind the screen then, and S29 data transmission Thread stops to receive data; S30 network on-line Thread stops network on-line; S31 waits for that the button Thread imports button with the user and transfer to application software and judge whether the user touches by waking key up, opens screen if "Yes" is then got back to S21, as if "No" S32 process ends then.This kind sleep mode is after S28 closes screen, this financial tape reading software also stops to receive data (S29), but network on-line Thread, data transmission Thread, data processing Thread all are ready (stand-by mode) with wait button Thread and really do not decommission fully, still take CPU (central processing unit) calculation resources to a certain degree.
In addition, though application software need not frame update again, but the frame updating Thread still continues running, after closing screen, stopping to receive data and stop network on-line, the user opens screen once more and promptly sees as shown in Figure 2 picture, and this is that representative picture is upgraded Thread still in running, so dialog box whether the visual inquiry user is online, and the financial tape reading software picture of background, so CPU (central processing unit) still continues computing under this pattern, do not reduce the power supply power consumption of CPU (central processing unit).And with the identical person of preceding paragraph park mode function mode, when the user only briefly does request for quote operation, end of operation must treat that idle setting-up time arrives and can start dormancy, during still waste the screen power supplies power consumption for some time.
See also Fig. 3, Fig. 3 is the process flow diagram that application software continues running behind the common mobile device financial tape reading software user manual-lock screen.The S40 person of being to use brings into use the mobile device financial tape reading software; S41 is the mobile device screen opening, and wait for that the button Thread promptly starts working this moment; S42 is that the picture that screen presents financial tape reading software is responsible for by the frame updating Thread; Then S43 sets up network on-line by the network on-line Thread; Treat that online back S44 data transmission Thread promptly begins to be responsible for receiving data, and be responsible for data processing by the data processing Thread; S45 frame updating Thread is the data of frame update with display update after the reception data; Then the S46 person of being to use operation and application software (for example change financial products, inquire about detailed quotation, inquire about real-time line chart ... etc.); S47 waits for that the button Thread imports button with the user and transfer to application software and judge whether the user touches by closing screen key, continues to receive data if "No" is then returned S44, as if "Yes" then S48 close screen; Be that S49 waits for that the button Thread imports button with the user and transfer to application software and judge whether the user touches by the unlatching screen key after screen is closed, if "No" then S50 data transmission Thread continues to receive data, and the data processing Thread continues deal with data, and S51 is by frame updating Thread frame update, then returns S49 again and waits for that the button Thread imports button with the user and transfer to application software and judge whether the user touches by the unlatching screen key; If S49 judges the user and touches by opening then S52 unlatching screen of screen key, then gets back to S44 and continue to receive data.This kind park mode is to control when close screen voluntarily by the user, compares with preceding two kinds of park mode function modes, and its advantage can be closed screen at once after the user briefly does request for quote operation, to reduce the waste of screen power supplies power consumption.But shortcoming pattern (S48) all application Threads after closing screen for this reason still continues running, comprise network on-line Thread, data transmission Thread, data processing Thread, frame updating Thread and wait for the button Thread, meaning is that CPU (central processing unit) still continues computing this moment, continues to consume power supply.
Because this pattern is when artificial control enters dormancy, so another shortcoming of pattern is to close screen as if forgetting behind user's data query, then the screen of mobile device will continue to consume power supply.Even the setting of the built-in auto sleep of mobile operating system is closed screen if the user forgets after using, close still gap for some time of screen automatically from operating system, during still waste the screen power supplies power consumption.This park mode function mode can control when enter park mode voluntarily by the user, but allows user's independence operation and application software, yet only partly mobile device is provided with and cuts out screen key, is not that all mobile devices all can use this mode of operation.
In sum, common mobile device financial tape reading software lacks electric power management mechanism, has the shortcoming of improving above-mentioned each mode only, and the user can prolong the financial tape reading software service time of existing mobile device.
Summary of the invention
