Abstract

The utility model provides a power source self-locking means of information processing system, comprising a self-locking unit and a trigger unit. The self-locking unit and the trigger unit cooperate with the Basic Input Output System (BIOS) to control the self locking of the power supply. When the information processing system is activated, the BIOS can drive the trigger unit, and the trigger unit can trigger the self-locking unit so that the purpose of self locking of the work power supply is attained.

Description

The power supply self-locking device of information handling system

Technical field

The utility model relates to a kind of power supply self-locking device, is meant a kind of power supply self-locking device that is applied to the working power of self-locking information handling system especially.

Background technology

In science and technology today at a tremendous pace, information handling system has been widely used in each field, and along with the continuous progress of science and technology, the also more and more polynary change of the function of information handling system, relative information handling system function is strong more, people are then extensive more to the field of its application, so formed a kind of inseparable relation between the mankind and the information handling system.

And information handling system is behind activating power, then entering duty starts working, because the content of work is complicated and loaded down with trivial details, so electronic installation (as: TV, mobile phone or general consumer electronics device) that information handling system is unusual, for activation work and power cut-off reaction is rapidly arranged, information handling system is usually before powered-down, and need a period of time to allow information handling system finish work miscellaneous, and after the content do one record storage with this task, can powered-down.

Summary of the invention

But general user is when using information handling system, can in work, make power-off by the error shock source switch occasionally, like this then can cause the interruption of work even data is run off, such situation also can form the infringement to information handling system simultaneously, also causes greatest inconvenience for the user.

In view of this, the utility model provides a kind of power supply self-locking device of information handling system, its purpose is the working power self-locking in addition with information handling system, with the power-off that prevents that false touch from being caused, the power supply self-locking device of the utility model information handling system, include from lock unit and trigger element, ROM-BIOS (BIOS) in the mating information disposal system is controlled the power supply self-locking simultaneously, when information handling system after activating, ROM-BIOS (BIOS) then drives trigger element, and trigger element triggers from lock unit, and reaches the purpose with the working power self-locking.

Relevant detailed content of the present invention and technology, existing conjunction with figs. is described as follows:

Embodiment

Please refer to Fig. 1, be the power supply self-locking device calcspar of the utility model information handling system.

The power supply self-locking device of information handling system of the present utility model, be arranged in the information handling system, more include ROM-BIOS 30 (BIOS) in this information handling system, this power supply self-locking device includes from lock unit 10, trigger element 20 and testing mechanism, wherein testing mechanism is arranged in the ROM-BIOS 30 (BIOS), be used to detect a power supply status, this power supply status is the power supply status of information handling system start, and present in this power supply status and to send a self-locking signal when stablizing and be sent to trigger element 20, trigger element 20 reaches with ROM-BIOS 30 (BIOS) and joins from lock unit 10, promptly send a trigger signals behind the trigger element 20 reception self-locking signals and make the action that is able to self-locking power switch SW from lock unit 10, switching-on and switching-off state PW can't be spread out of.

Next enumerate an embodiment with regard to the utility model, do further describing in detail, please refer to Fig. 2, for the power supply self-locking device of the utility model information handling system is implemented illustration.

Reverse assembly 11 and the logic module 12 of in lock unit 10, more including of the present utility model, wherein this reverse assembly 11 can be a reverser (Inverter), and logic module can be one with the door (an AND gate), oppositely the input end and the power switch SW of assembly 11 join, also join simultaneously with pre-stand-by power source SP, when normality, present " H " state, through reverse assembly 11 oppositely after then for " L " and state be sent to the input end of logic module 12, but when power switch SW is activated, oppositely the input end of assembly 11 then presents " L " state, the output terminal of reverse assembly 11 is then presented " H " state (activation signal) be sent to logic module 12, logic module 12 another input ends then connect trigger element 20 and pre-stand-by power source SP, when normality, present " H " state, if this moment logic module 12 two input ends be all " H " and state (be that trigger element does not trigger, and receive activate signal), then with output terminal by " L " state transfers to " H " and state.

Receive when trigger element 20 detecting unit the self-locking signal after, then send a trigger signals, make the pre-stand-by power source SP on logic module 12 input ends guide to trigger element 20, one input end normality of logic module 12 is rendered as " L " state, like this then output normality effectively steering logic assembly 12 is " L " state, can not be subjected to the influence of the action of power switch SW, reach the purpose of power supply self-locking.

Do a detailed description with regard to detecting unit of the present utility model and execution flow process at last, please refer to Fig. 3, be the power supply self-locking device flowchart of the utility model information handling system.

Active information disposal system (flow process 300) at first, begin to detect power supply status (flow process 310) by testing mechanism then, this flow process promptly utilizes testing mechanism to detect the start power supply status of information handling system, when presenting when stablizing, this power supply status sends a self-locking signal (flow process 320) by testing mechanism, and the self-locking signal is sent to trigger element (flow process 330), trigger from lock unit power switch self-locking (flow process 340) by trigger element at last.

Though the aforesaid preferred embodiment of the utility model discloses as above; so it is not in order to limit practical range of the present utility model; be not to be used for limiting practical range of the present utility model; anyly know this field skill person; the equalization of being done in not breaking away from spirit of the present utility model and claim changes and modifies; be all the utility model claim and contain, so scope of patent protection of the present utility model must be looked this instructions and the claim person of defining is as the criterion.
