Description
Technical field
The present invention relates to the method and the system thereof of a kind of power management and security protection, relate in particular to a kind of method of carrying out power management by the ultrasonic inductor.
Background technology
Advance rank configuration and power interface (ACPI, Advanced Configuration and PowerInterface), operating system in the computer system, peripheral equipment, central processing unit, all kinds of embedded microcontroller, bus itself and the mutual management of power supply usefulness, monitoring temperature, reserve power supplies management have been integrated.Allow operating system, CPU (central processing unit) and peripheral equipment integrate, intercourse power supply and use information, easier and profitable ground managed together power supply.
In brief, advancing rank configuration and power interface can be according to user's supply whether operational computations machine system comes managing electrical power, for example when the user leaves computer system, computer system is also calculated one period schedule time and is not had operation by after the action as peripheral devices such as mouse, keyboards, with equipment such as the display of the system of shutting down computer or memory storages, be that computer system has entered park mode, to save the consumption of computer system electric energy.And when getting back to peripheral devices such as computer system operation mouse or keyboard once more as the user, computer system will be waken up and equipment such as opening display or memory storage once more, make computer system return to operational mode.
The powder source management mode of aforementioned calculation machine system, really can be under the situation that computer system was not used in a schedule time, enter park mode and save the consumption of electric energy, yet after the user leaves to enter park mode during this period of time in the middle of, the user system that do not use a computer, but electric energy is to continue consuming the still power saving of non-the best design.Moreover after the user left, other people can be to the computer system line operate that advances, and makes computer system get back to operational mode by park mode, can steal the relevant information of computer system, and the mechanism of security protection can't be provided.
In order to solve the above problems, the U.S. announces the 7196720th patented claim and discloses a kind of method and device with the electronic device power startup that detects the action video camera, No. 7196720 patented claim is to be connected to an electronic installation by a video camera, make electronic installation under sleep pattern, when video camera detected action, electronic installation was from sleep pattern or other power down mode power initiations.
And for example the U.S. announces the 6418536th patented claim and discloses a kind of power conservation type portable computer that uses the human body sensing apparatus, No. 6418536 patented claim is to have the sensing apparatus that detects user's function by one, when the user leaves computing machine, the OnNow electricity-saving function.
Above-mentioned patented claim is by video camera or sensing apparatus, allowing the acquisition user's that computer system can be instant status information, as leaves or near computer system, with certain realization purpose of power saving.And for security protection, generally can adopt the Password Management technology, in the time of also can working as the user near computer system, computer system promptly starts the password input frame, the user must use keyboard input preset password, can make computer system enter into operational mode, therefore, computer system must be kept the power supply supply of video camera, sensing apparatus and keyboard simultaneously.Or, be equiped with video camera as computer system, can utilize the captured image of video camera to carry out face recognition technology, but face recognition technology is comparatively complicated as security protection.Be with, at present computer system all still remains to be improved for power management and security protection.
Summary of the invention
Existing computer computer system is at power management and security protection part, though passed through the state that video camera or induction installation can immediately obtain the user, to realize instant power-saving control, but, cause the complexity of computer system for adopting the Password Management technology in the security protection or adopting face recognition technology.In view of this, the present invention proposes a kind of ultrasonic inductor that utilizes simultaneously as power management and the power management of security protection identification and the system and the method thereof of security protection.
The system of power management disclosed according to the present invention and security protection, be applied on the computer system, it includes a frequency controller and an inductor at least, frequency controller can be controlled inductor and send high-frequency signal or low frequency signal, when electronic installation is under the operational mode, frequency controller control ultrasonic inductor sends low frequency ultrasonic signal, to detect the positional information of user with respect to computer system, and then make computer system enter park mode, or enter into recognition mode by park mode by operational mode.Enter into recognition mode and work as computer system by park mode, frequency controller control inductor sends high-frequency signal, inductor detects user's action message, discerns by default action password and action message, and then makes computer system return to operational mode.
The method of power management disclosed according to the present invention and security protection, it includes following steps:
Computer system is carried out an operational mode;
