TABLE 3 application name and working scenario correspondence table

Fig. 2 shows a flow chart of a power management method 200 according to one embodiment of the invention. Method 200 is suitable for execution in computing device 100, and method 200 may include steps 210 through 240.

By the method 200, a method for automatically managing power is provided, a user does not need to learn a setting mode, and user experience is improved. Specifically, the resource working mode suitable for the working scene is adjusted under different working scenes, so that the normal operation of the process under the current working scene is ensured, the occupation of resources is reduced as much as possible, the use of electric quantity is reduced, and the power supply endurance of the computing equipment is improved.

The implementation executes step 210 to determine the current working scenario, which is any one of a daily office scenario, an entertainment scenario, and a game scenario, that is, the current working scenario corresponds to only one working scenario. In some embodiments, the working process of determining the current working scenario is as follows:

first, process information of all started processes is scanned, where the process information includes process name, process state information and resource usage information, and the resource usage information may be set according to an actual application scenario, which is not limited by the present invention, and for example, the resource usage information includes CPU utilization. The process state information includes values of the process state and state, and can also be understood as state codes corresponding to the process state and the process state, where the corresponding relationships of the process state, the state meaning and the corresponding state codes are shown in table 4.

TABLE 4 correspondence table of process states, state meanings, and corresponding state codes

As can be seen from Table 4, the process states include run (indicating running or waiting in a run queue, indicated by state code R), interrupt (indicating dormant, blocked, waiting for the formation of a condition or receiving a signal, indicated by state code S), non-interruptible (indicating that the received signal is not awake and non-operational, the process must wait until an interrupt occurs, indicated by state code D), dead (indicating that the process has terminated, but the process descriptor exists, until the parent process invokes wait4 () system call, indicated by state code Z), and stopped (indicating that the process stops running after receiving SIGTOP, SIGSTP, SIGTOU signal, indicated by state code T).

After the process information of the started process is determined, the started application name is determined according to the process name of each process, and the working scene corresponding to each application name is matched from the corresponding relation between the application name and the working scene to serve as a target scene. And then according to the resource utilization information of each process, calculating the total utilization rate of resources, wherein the specific mode for calculating the total utilization rate of resources can be set according to the actual application scene, and the invention is not limited to the specific mode. For example, the sum processing is performed on the values of the resource usage information of each process, and the sum processing result is taken as the total usage rate of the resources, and taking the resource usage information as the CPU usage rate as an example, the specific way of calculating the total usage rate of the resources is as follows: and carrying out summation processing on the CPU utilization rate of each process, and taking the summation processing result of the CPU utilization rate as the total utilization rate of resources.

After determining the total utilization rate of resources, judging whether the target scene is a combined scene, if so, determining the type of the combined scene, and determining the current working scene according to the type of the combined scene and the total utilization rate of resources, otherwise, setting the current working scene as the target scene, and specifically:

if the combined scene type is the first type (the combined scene corresponding to the daily office scene and the entertainment scene), judging whether the total utilization rate of the resources is smaller than a first preset value, if so, setting the current working scene as the daily office scene, and if not, setting the current working scene as the entertainment scene.

If the combined scene type is the second type (the combined scene of the daily office scene and the game scene), judging whether the total utilization rate of the resources is smaller than a first preset value, if so, setting the current working scene as the daily office scene, otherwise, setting the current working scene as the game scene.

If the combined scene type is the third type (the combined scene corresponding to the entertainment scene and the game scene), judging whether the total utilization rate of the resources is between a first preset value and a second preset value, if so, setting the current working scene as the entertainment scene, otherwise, setting the current working scene as the game scene.

If the combined scene type is the fourth type (the combined scene corresponding to the daily office scene, the game scene and the entertainment scene), judging whether the total utilization rate of the resources is lower than a first preset value, if yes, setting the current working scene as the daily office scene, if not, continuously judging whether the total utilization rate of the resources is between the first preset value and a second preset value, if so, setting the current working scene as the entertainment scene, otherwise, setting the current working scene as the game scene.

The first preset value and the second preset value can be set according to the actual situation and the actual application scene of the equipment in the computing equipment, which is not limited by the invention. For example, the first preset value may be 30% and the second preset value may be 50%.

After determining the current operating scenario, step 220 is continued with determining resources that support power consumption optimization, i.e. resources that can adjust the operating mode. In some embodiments, step 220 comprises:

firstly judging whether a power node exists in the resource, if so, determining that the resource supports power consumption optimization, otherwise, determining that the resource does not support power consumption optimization. Under the condition that the resources support power consumption optimization, a power consumption optimization list is generated, and the power consumption optimization list comprises resource identifiers capable of performing power consumption optimization, so that which resources can be subjected to power consumption optimization can be determined according to the power consumption optimization list. If the resource does not support power consumption optimization, execution of the program is ended. For example, the power consumption optimization list includes the resource CPU, the independent graphics card and the hard disk, that is, in this case, in the computing device, only the CPU, the independent graphics card and the hard disk support power consumption optimization, and other devices do not support power consumption optimization.

In order to reduce consumption of electricity caused by occupation of resources by the inactive process, when determining that the target scene is a combined scene, in some embodiments, the present invention further freezes the inactive process, which specifically includes:

first, the correspondence between the combined scene and the black-and-white list is traversed, for example, the correspondence table between the combined scene and the black-and-white list shown in table 1 is traversed, and the black-and-white list corresponding to the target working scene is determined. And determining an active process and an inactive process according to the process state information of each process. After determining an active process and an inactive process according to the process state information, according to the determined process processing rules in the black-and-white list, performing dormancy processing on the inactive processes except the social application process and the preset application process, and reserving the active process.

For example, as can be seen from table 1, when the target working scenario is a combined scenario of the first type and the second type, inactive processes except for the social application process in all started processes of the computing device are subjected to dormancy processing, and active processes are reserved. And when the target working scene is a combined scene of the third type and the fourth type, performing dormancy processing on inactive processes except for the social application process and the music player process in all started processes of the computing device, and reserving the active processes.

In the present invention, as the process state shown in table 4, a process whose process state is running (i.e., state=r) is set as an active process, and the other processes are all set as inactive processes. Therefore, by freezing the inactive process, the electric quantity is saved, and the power supply endurance of the computing equipment is further improved.

After determining the resource supporting the power consumption optimization, step 230 is continuously executed, and the resource power consumption optimization information corresponding to the current working scenario is matched from the corresponding relation between the working scenario and the resource power consumption optimization information, so as to serve as the target power consumption optimization information, specifically:

and matching the resource power consumption optimization information corresponding to the current working scene from the corresponding relation table of the working scene and the resource power consumption optimization information, and taking the resource power consumption optimization information as target power consumption optimization information. Taking the current working scenario as a daily office scenario as an example, the resource power consumption optimization information which can be matched from table 2 and corresponds to the daily office scenario is: the independent display card is closed, the working mode of the CPU is an energy-saving mode, the hard disk is a low-power consumption mode, and the working mode of the PCI bus enabling equipment is an automatic mode.

After the resource power consumption optimization information corresponding to the current working scenario is matched, step 240 is executed finally, and the working mode of each supported power consumption optimization resource is updated to the optimized working mode corresponding to each supported power consumption optimization resource in the target power consumption optimization information. Specifically, the working modes of the resources in the power consumption optimization table are updated to the optimized working modes corresponding to the supported power consumption optimization resources in the target power consumption optimization information.

For example, the determined power consumption optimization list includes a resource CPU, an independent display card and a hard disk, and the resource power consumption optimization information matched from table 2 and corresponding to the daily office scenario is: the independent display card is closed, the working mode of the CPU is an energy-saving mode, the hard disk is a low-power consumption mode, and the working mode of the PCI bus enabling equipment is an automatic mode. Then, at this time, the working mode of the CPU of the computing device is set to be an energy-saving mode, the hard disk is set to be a low-power mode, and the independent graphics card is turned off, so that the working mode of each resource in the power consumption optimization table is updated to be an optimized working mode corresponding to each supported power consumption optimization resource in the target power consumption optimization information.

Therefore, the working mode of adjusting resources through the current working scene is realized, so that the power consumption is reduced. Steps 210 through 240 are performed each time it is desired to extend the power endurance of the computing device.

Fig. 3 shows a block diagram of a power management apparatus 300 according to an embodiment of the invention. The apparatus 300 includes a work scenario determination module 310, a support power consumption optimization resource determination module 320, a power consumption optimization information determination module 330, and a power management module 340, which are coupled in sequence.

The working scenario determination module 310 is adapted to determine a current working scenario.

The power consumption optimization supporting resource determining module 320 is adapted to determine resources supporting power consumption optimization.

The power consumption optimization information determining module 330 is adapted to match the resource power consumption optimization information corresponding to the current working scenario determined by the working scenario determining module 310 from the corresponding relation between the working scenario and the resource power consumption optimization information, as target power consumption optimization information.

The power management module 340 is adapted to update the operation mode of each supported power consumption optimization resource determined by the supported power consumption optimization resource determining module 320 to the optimized operation mode corresponding to each supported power consumption optimization resource in the target power consumption optimization information determined by the power consumption optimization information determining module 330.
