Wherein, description of reference numerals is following:
110～160 steps
Embodiment
Fig. 1 is the process flow diagram of the method for managing power supply of a kind of mancarried device among the present invention, and it comprises the following step:
Step 110: carry out an application program.
Step 120: judge when carrying out this application program whether need adjust the power supply that is supplied to a specific hardware module in the mancarried device: if, execution in step 130; If not, execution in step 150.
Step 130: judge the historical behaviour in service when this specific hardware module had before been carried out this application program.
Step 140: supply the power supply of specific hardware module so far according to historical behaviour in service adjustment.
Step 150: judge whether to continue executive utility: if, execution in step 110; If not, execution in step 160.
Step 160: close and supply the power supply of specific hardware module so far.
The present invention can be used on mancarried devices such as smart mobile phone, notebook computer, palm PC, and one or more hardware modules capable of using are carried out different application in step 110.For instance; When the application program that is relevant to photograph/photography was installed by institute in carrying out mancarried device, the user can browse photo through a display module, play audio-visual grade through a playing module; Through a GPS (global positioning system; GPS) module indicates the spot for photography of photo, or through a Wireless Fidelity (wireless fidelity, WiFi) module with photo/uploading films to network.Perhaps, during the movie application program of in carrying out mancarried device, being installed, the user can play film through a playing module, in the process of ornamental film, also can receive incoming call through a conversation module at any time.
In step 120, whether the present invention can judge when carrying out this application program, need adjust and supply the power supply of specific hardware module so far.For instance, when step 110 began to carry out the application program that is relevant to photograph/photography, mancarried device possibly only opened display module; When carrying out the movie application program, mancarried device possibly opened playing module and conversation module simultaneously.
According to personal like or use habit, be not that all users need all functions at every turn when executive utility.For instance, when execution was relevant to the application program of photograph/photography, some user possibly seldom use camera function, and some user possibly never open positioning function or function of surfing the Net; When carrying out the movie application program, some user maybe be mostly at the ornamental film at midnight, so incoming call is seldom arranged during the course.Therefore in step 130; The present invention can judge the historical behaviour in service when this specific hardware module had before been carried out this application program: the utilization rate of all hardware module when the application program that is relevant to photograph/photography is carried out in the inherence to a scheduled period; Display module may be judged as the hardware module of a high utilization rate, and playing module, GPS module and WiFi module may be judged as the hardware module of low utilization rate; The utilization rate of all hardware module during to inherent execution of scheduled period movie application program, playing module may be judged as the hardware module of a high utilization rate, and the conversation module may be judged as the hardware module of a low utilization rate.
Mancarried device is when running, and the operating mode of each hardware module roughly is divided into normal mode, battery saving mode and " shut " mode".Under normal mode, preset power supply can be provided, let hardware module be in normal operating conditions at any time, this moment, electrical source consumption was maximum.Can close power supply fully in that " shut " mode" is next, this moment can electric consumption, but needs one section wakeup time just can return back to normal operating conditions when restarting.According to different system or manufacturer's definition; Different titles such as battery saving mode can be awaited orders, dormancy or sleep pattern; But its principle all is only to provide to preserve the required minimum power supply of data; Therefore the power consumption of battery saving mode is lower than normal mode, and when restarting required wakeup time than " shut " mode" for short.
In step 140, the present invention can the historical behaviour in service according to each hardware module adjust its power supply when executive utility.Suppose in step 130 display module is judged to be the hardware module of a high utilization rate, and playing module, GPS module and WiFi module are judged to be the hardware module of low utilization rate.When execution was relevant to the application program of photograph/photography, if only display module is arranged in running, the power supply that is supplied to playing module, GPS module and WiFi module was closed in meeting of the present invention in step 140; If only playing module is arranged in running, meeting of the present invention reduces the power supply that is supplied to display module in step 140, and closes the power supply that is supplied to GPS module and WiFi module.In like manner; When carrying out the movie application program; If playing module with the foreground mode operating module of conversing with the backstage mode operating; The power supply that is supplied to the conversation module is closed in meeting of the present invention in step 140: if playing module is with the backstage mode operating with the foreground mode operating for the conversation module, meeting of the present invention reduces the power supply that is supplied to playing module in step 140.
As previously mentioned, if when executive utility, do not need to use, the power supply that is supplied to low utilization rate hardware module is closed in meeting of the present invention fully, to reach best power saving effect.According to the historical behaviour in service of hardware module, the probability that the user need use low utilization rate hardware module afterwards is not high, even receive the indication that minority restarts, the odd word wakeup time can't significantly influence the usefulness of mancarried device.
On the other hand, if when executive utility, do not need to use, the present invention can reduce the power supply of the paramount utilization rate hardware module of supply, to reach the part power saving effect.According to the historical behaviour in service of hardware module, the user very likely can use high utilization rate hardware module afterwards, therefore through providing minimum power supply to shorten wakeup time, to take into account power saving and system effectiveness simultaneously.
To each hardware module in the mancarried device; The present invention can judge the historical behaviour in service when it had before carried out an application program; And when carrying out this application program, come adjustment automatically to be supplied to the power supply of corresponding hardware module according to historical behaviour in service; In the time need not using, close the power supply that is supplied to low utilization rate hardware module fully, and reduce the power supply of the paramount utilization rate hardware module of supply, therefore can take into account power saving and system effectiveness simultaneously.
The above is merely the preferred embodiments of the present invention, and all equalizations of doing according to claim of the present invention change and modify, and all should belong to covering scope of the present invention.
