Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
Embodiment one:
The present embodiment provides a kind of method of control terminal, the method is applied to as terminals such as smart mobile phone, panel computer, intelligent watch, intelligent glasses, these terminals at least have three power consumption states, i.e. the first power consumption state, the second power consumption state and the 3rd power consumption state, wherein, power consumption when terminal is in the first power consumption state is lower than the power consumption of end when the second power consumption state, and power consumption when terminal is in the second power consumption state is less than power consumption when terminal is in the 3rd power consumption state.
In the present embodiment, when terminal is in the first power consumption state, all processes in terminal, namely kernel state process and User space process all stop running, namely frozen, device quits work at least partially, wherein, this at least partially device can, for all devices except the device relevant to clocking capability except in terminal, also can be the part of devices in terminal except the device relevant to clocking capability; When terminal is in the second power consumption state, the kernel state process in terminal and Part I device are work, and User space process is still frozen, and other device at least partially in device still quits work; When terminal is in the 3rd power consumption state, kernel state process in terminal and User space process are normally run, Part II proper device operation, wherein, the quantity of Part II device is greater than the quantity of Part I device, and when entering the first power consumption state with terminal, out-of-work device at least partially can be the same or different.
Fig. 1 is the method flow schematic diagram of the control terminal in the embodiment of the present invention one, and shown in Figure 1, the method comprises:
S101: when terminal is in the first power consumption state, and when preset duration reaches, switch to the second power consumption state; Wherein, switch to the second power consumption state, comprising: the kernel state process running terminal and the Part I device waken up in terminal, and keep the User space process in terminating terminal to run, wherein, Part I device is used for realizing preset function;
Specifically, terminal is after being controlled by the user or being certainly advanced into the first power consumption state, according to preset duration, start timing, when preset duration reaches, namely when timing reaches, the kernel state process of terminal operating self and wake Part I device up, namely controls Part I devices function, now, User space process keeps stopping running, and namely User space process keeps freezing.
In specific implementation process, Part I device is the preset function that will carry out to terminal timing wake-up is corresponding.Such as, terminal timing wake-up is to communicate with server, and so, Part I device can comprise the radio-frequency module, baseband processor etc. of terminal; For another example, terminal timing wake-up is to upgrade display, and so, Part I device can comprise video-stream processor, display module etc., and the present invention does not do concrete restriction, is as the criterion with practical application.
More preferably, Part I device at least comprises a display module, and so, when terminal is in the first power consumption state, display module work also keeps display.Such as, terminal is intelligent watch, and display module is LCDs, so, when intelligent watch is in the first power consumption state, and the long bright and displaying time of LCDs.Certainly, display module can also be touch display screen, electronic ink screen, Electronic Paper etc., and the present invention is not specifically limited.
Further, above-mentioned wake Part I device up before, the method also comprises: according to preset function, determines corresponding Part I device.That is, terminal also needs according to preset function, determines which the Part I device needing to wake up has.
In another embodiment, before S101, user can control terminal, or terminal triggers voluntarily and enters the first power consumption state, and so, the method also comprises: obtain second system power consumption switching command; Perform second system power consumption switching command, stop User space process and the operation of kernel state process, and after termination kernel state process is run, control terminal enters the first power consumption state.
Specifically, user can pass through as screen locking in the process using terminal, the operations such as offline mode, control terminal enters the first power consumption state, certainly, terminal also automatically can trigger and enter the first power consumption state, now, terminal obtains second system power consumption switching command, and namely indicating terminal switches to the first power consumption state.So, terminal stops run user state process and kernel state process, and after kernel state procedure termination is run, control above-mentioned device at least partially and quit work, so, control terminal enters the first power consumption state, as dormant state.
Further, because User space process is run in the user space, kernel state process is run in kernel spacing, can think that User space process and kernel state process are separate, so, above-mentioned execution second system power consumption switching command, the step stopping User space process and the operation of kernel state process can also comprise: perform second system power consumption switching command, stop User space process and the operation of kernel state process successively, that is, terminal performs second system power consumption switching command, first stop the operation of User space process in the user space, then, the operation of kernel state process is stopped again in kernel spacing, and when stopping kernel state process and running, for timer setting preset duration, start timing.
Preset duration mentioned here refers to the timing duration of terminal timing wake-up, and can be 1 second, 5 seconds, 8 seconds, 10 seconds, 1 minute etc., be as the criterion with practical application, the present invention be not specifically limited.
In actual applications, as mentioned above, suppose that terminal is intelligent watch, Part I device at least comprises a display module, now, preset duration just can set according to the time showing mode of intelligent watch, if last position of the clock display of intelligent watch is minute, so, preset duration just can be set to 1 minute; If last position of the clock display of intelligent watch is second, so, preset duration just can be set to 1 second.
In such scheme, preset duration is fixing duration, preset, and in another case, preset duration can also adjust according to current system time by terminal system developer or manufacturer before terminal is dispatched from the factory.Such as, still suppose that terminal is intelligent watch, after the screen locking of intelligent watch 30 points of 45 seconds response users 9 time operates and enters the first power consumption state, according to current system time, preset duration can be configured to 15 seconds, then, after preset duration arrives, intelligent watch performs S101.And after this, intelligent watch still according to the preset duration that system development business or manufacturer preset before it dispatches from the factory, as 1 minute carries out timing.Certainly, in specific implementation process, can also there is other setting situation in preset duration, the present invention is not specifically limited.
Further, switch in the process of the second power consumption state in terminal by the first power consumption state, user also can thoroughly wake terminal up by such as unlocking, closing the wake operation such as offline mode, now, timer reset, waits for that terminal enters the first power consumption state again, again starts timing.
S102: perform preset instructions, call kernel state process and Part I device, after completing preset function, stops kernel state process and runs, and controls Part I device and quit work, and makes terminal again enter the first power consumption state.
Specifically, after terminal switches to the second power consumption state by S101, terminal performs preset instructions, calls kernel state process and Part I device to complete preset function.After preset function completes, control kernel state procedure termination and run, namely again freeze kernel state process, and control Part I device quits work again, like this, terminal enters the first power consumption state again.

S201: when terminal is in the first power consumption state, and when preset duration reaches, switch to the second power consumption state; Wherein, switch to the step of the second power consumption state, comprising: the kernel state process running terminal and the Part I device waken up in terminal, and keep the User space process in terminating terminal to run, wherein, Part I device is used for realizing preset function;
Specifically, terminal is after being controlled by the user or being certainly advanced into the first power consumption state, according to preset duration, start timing, when preset duration reaches, namely when timing reaches, the kernel state process of terminal operating self and wake Part I device up, namely controls Part I devices function, now, User space process keeps stopping running, and namely User space process keeps freezing.
In specific implementation process, Part I device is the preset function that will carry out to terminal timing wake-up is corresponding.Such as, terminal timing wake-up is to communicate with server, and so, Part I device can comprise the radio-frequency module, baseband processor etc. of terminal; For another example, terminal timing wake-up is to upgrade display, and so, Part I device can comprise video-stream processor, display module etc., and the present invention does not do concrete restriction, is as the criterion with practical application.
More preferably, Part I device at least comprises display module, and so, when terminal is in the first power consumption state, display module work also keeps display.Such as, terminal is intelligent watch, and display module is LCDs, so, when intelligent watch is in the first power consumption state, and the long bright and displaying time of LCDs.Certainly, display module can also be touch display screen, electronic ink screen, Electronic Paper etc., and the present invention is not specifically limited.
Further, above-mentioned wake Part I device up before, the method also comprises: according to preset function, determines corresponding Part I device.That is, terminal also needs according to preset function, determines which the Part I device needing to wake up has.
In another embodiment, before S201, user can control terminal, or terminal triggers voluntarily and enters the first power consumption state, and so, the method also comprises: obtain second system power consumption switching command; Perform second system power consumption switching command, stop User space process and the operation of kernel state process, and after termination kernel state process is run, control terminal enters the first power consumption state.

Further, because User space process is run in the user space, kernel state process is run in kernel spacing, can think that User space process and kernel state process are separate, so, above-mentioned execution second system power consumption switching command, the step stopping User space process and the operation of kernel state process can also comprise: perform second system power consumption switching command, stop User space process and the operation of kernel state process successively, that is, terminal performs second system power consumption switching command, first stop the operation of User space process in the user space, then, the operation of kernel state process is stopped again in kernel spacing, and when stopping kernel state process and running, for timer setting preset duration, start timing.
Preset duration mentioned here refers to the timing duration of terminal timing wake-up, and can be 1 second, 5 seconds, 8 seconds, 10 seconds, 1 minute etc., be as the criterion with practical application, the present invention be not specifically limited.
In actual applications, as mentioned above, still suppose that terminal is intelligent watch, Part I device at least comprises a display module, now, preset duration just can set according to the time showing mode of intelligent watch, if last position of the clock display of intelligent watch is minute, so, preset duration just can be set to 1 minute; If last position of the clock display of intelligent watch is second, so, preset duration just can be set to 1 second.
In such scheme, preset duration is fixing duration, preset, and in another case, preset duration can also adjust according to current system time by terminal system developer or manufacturer before terminal is dispatched from the factory.Such as, still suppose that terminal is intelligent watch, after the screen locking of intelligent watch 30 points of 45 seconds response users 9 time operates and enters the first power consumption state, according to current system time, preset duration can be configured to 15 seconds, then, after preset duration arrives, intelligent watch performs S201.And after this, intelligent watch still according to the preset duration that system development business or manufacturer preset before it dispatches from the factory, as 1 minute carries out timing.Certainly, in specific implementation process, can also there is other setting situation in preset duration, the present invention is not specifically limited.
Further, switch in the process of the second power consumption state in terminal by the first power consumption state, user also can thoroughly wake terminal up by such as unlocking, closing the wake operation such as offline mode, now, timer reset, waits for that terminal enters the first power consumption state again, again starts timing.
S202: perform preset instructions, call kernel state process and Part I device, after completing preset function, stops kernel state process and runs, and controls Part I device and quit work, and makes terminal again enter the first power consumption state.
Specifically, after terminal switches to the second power consumption state by S201, terminal performs preset instructions, calls kernel state process and Part I device to complete preset function.Such as, preset function is for upgrading display, and so, terminal calls kernel state process and display module, upgrades the displaying contents that display module is current.After preset function completes, control kernel state procedure termination and run, namely again freeze kernel state process, and control Part I device quits work again, like this, terminal enters the first power consumption state again.
For example, suppose that preset function is for upgrading display, so, terminal calls kernel state process and display module, upgrades the displaying contents that display module is current.Further, if terminal is intelligent watch, upgrading the current displaying contents of display module just can for upgrading the clock of display module display.

Specifically, because the first system power consumption switching command can be that user triggers at any time, so now terminal may be in the first power consumption state, also may the second power consumption state.When terminal is in the first power consumption state, terminal is waken up all processes and device with regard to needs, and when terminal is in the second power consumption state, terminal only needs to wake up Partial Process and device.
So in order to reduce the data processing amount of terminal, avoid repeatedly waking up, terminal, after receiving the first system power consumption switching command, performs this instruction, judges whether kernel state process is run, determine the current residing power consumption state of terminal thus.
S205a: when kernel state process off-duty, runs kernel state process and User space process, and wakes the Part II device in terminal up, make terminal enter the 3rd power consumption state;
Specifically, when terminal determination kernel state process off-duty, illustrate that terminal is in the first power consumption state, now, terminal operating kernel state process and User space process, and wake the Part II device in terminal up, make terminal enter the 3rd power consumption state.
S205b: when kernel state process is run, run user state process, and wake the Part III device in terminal up, make terminal enter the 3rd power consumption state.
