Embodiment
Describe the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, computer electric power management device of the present invention comprises: detecting unit, judging unit, computer control unit.Wherein, before said detecting unit is used to detect the user and whether is positioned at computing machine, and testing result sent to judging unit; Said judging unit is used to obtain the state of operating system, and according to the User Status that the state and the detecting unit of operating system sends over, sends corresponding control signal to computer control unit; Said computer control unit is used to receive the control signal that judging unit sends over, and only when said control signal is effective control signal, computing machine is carried out corresponding operating, makes computing machine get into the powder source management mode that the user sets.
The implementation of computer electric power management device of the present invention is:
Step 101, detection user sends to judging unit with testing result before whether being positioned at computing machine;
Step 102, judging unit are obtained the state of operating system, and according to the User Status that the state and the detecting unit of operating system sends over, send corresponding control signal to computer control unit;
Step 103, computer control unit receives the control signal that judging unit sends over, and only when said control signal is effective control signal, computing machine is carried out corresponding operating, makes computing machine get into the powder source management mode that the user sets.
Wherein: only be not positioned at before the computing machine for the user and the state of said operating system when being idle condition when said User Status, the control signal that said judging unit sends is effective control signal.
Below be that example is carried out detailed explanation to the present invention with the notebook computer, it is understandable that this embodiment is a preferred embodiment of the present invention, and the present invention is not limited to the application on notebook computer.
As shown in Figure 2, detecting unit is a camera module, and this camera module comprises imageing sensor and data processing chip.Imageing sensor comprises camera lens and sensor chip two parts (figure does not show), and optical signallings such as the brightness that sensor chip will obtain from camera lens, color convert corresponding electric signal to, and electric signal is sent to data processing chip.Data processing chip is handled the image information that receives, and the signal such as the USB differential signal that convert computer general-purpose to send to computing machine.Simultaneously, the driving of data processing chip combining image information and camera is discerned the back to image and is sent the high-low level signal to judging unit.
Below in conjunction with Fig. 3 the Identification of Images flow process of camera module is described.
Step 301, imageing sensor are obtained external image information, and convert thereof into electric signal and send to data processing chip;
Whether comprise figure information in the image information that step 302, data processing chip inspection receive from imageing sensor, like the profile of the particular color of the profile of portrait, portrait, some key positions of human body face and color etc.;
Step 303, when not comprising figure information in the image information, data processing chip output high level is to judging unit.
Further, judging unit comprises logic gates and system status register.System status register is used to obtain the state of operating system, and the status information of operating system is sent to logic gates; The status information of the operating system that logic gates is used for system status register is sended over and the user state information that detecting unit sends over are handled, and send corresponding control signal to computer control unit.Specifically, when operating system is before idle condition and user are not positioned at computing machine the time, two inputs of logic gates are high level; At this moment; It is output as low level, and this is effective control signal, and logic gates is all exported high level in other cases.
Computer control unit comprises embedded controller (EC), timer and power management module.EC is used to receive the control signal that judging unit sends over, and the timing message of triggering timing device and reception timer, sends corresponding signal and gives power management module.The control signal that only sends over when judging unit is effective control signal when being low level signal, after EC triggering timing device, timer run to the time that the user sets; Send message to EC; EC judges whether control signal remains valid, and in the time of effectively, sends corresponding signal and gives power management module.
Timer is used for the setting of various times of line related management mode, is triggered by EC, and clocking information is sent to EC.
Power management module is used to receive the information of EC, and computing machine is carried out corresponding operating, makes computing machine get into the management mode that the user sets.Power management module comprises control signal relevant with power management on the computer motherboard and power management software, and software can read hardware signal and make corresponding action.The user can set the timing of powder source management mode and timer in power management module, powder source management mode wherein comprises that computing machine gets into holding state, computing machine gets into dormant state, CPU frequency reducing or cuts out associated peripheral.
Said computer control unit also can not comprise timer, after the control signal that EC reception judging unit sends over, directly sends corresponding signal and gives power management module.
For those of ordinary skills; It is understandable that; This part work of EC can be accomplished by the partial circuit of chipset south bridge in desktop computer, therefore the invention is not restricted to notebook computer, in the foregoing description EC just can be applicable to desktop computer with the partial circuit replacement of chipset south bridge.Difference only is that code all has been solidified into hardware in the partial circuit of chipset south bridge, cannot upgrade, and EC is more flexible, can upgrade when its code needs, but these does not influence and realize power management function of the present invention.
Treatment scheme when introducing computer electric power management method of the present invention and in notebook computer, use below in conjunction with Fig. 2 and Fig. 4:
Those skilled in the art should understand and realize easily; As long as detecting unit also can be infrared facility, ultrasonic unit or other can detect the device before whether the user is positioned at computing machine; These devices can both send to judging unit with user state information, thereby realize power management purpose of the present invention.
