Abstract
The method includes following steps: using inductor to provide signal of inducing movement of hard disc; based on intensity of induced signal, processor of induction signal determines whether dropped out hard disc reaches to the preset endured intensity; if yes, cutting off control circuit for hard disc, and power supply for hard disc; if no, retaining control circuit for hard disc, and power supply for hard disc.
Description
Technical field
The present invention is meant a kind of hard-disc drop protection method especially about a kind of hard disk protecting method.
Background technology
Along with the development of infotech, various electronic products are widely applied in daily life and the work, for example computing machine.And hard disk also uses widely because of a kind of typical information storage equipment as electronic product.The transmission of data information for convenience with carry, portable hard drive also becomes the instrument that a lot of business people or research staff use always.Usually portable hard drive is made up of traditional hard disk and hard-disk cartridge, and hard-disk cartridge provides the conversion of the connecting interface of conventional hard, and portable hard drive can be connected with computing machine with the realization plug and play by USB interface, thereby improves the ease of use of conventional hard.
Yet, because mostly portable hard drive is on computers external, normally be placed on certain position temporarily, it is not fixed yet, this makes the accident that hard disk drops that is moved sometimes in using the portable hard drive process, because this moment, the magnetic head and the video disc distance of hard disk were very near, make magnetic head be easy to bump against video disc, directly cause the breaking-up of portable hard drive, and its data that has stored is lost, this brings direct economic loss and inconvenience greatly to the user, even causes bigger indirect economic loss, such as the loss of vital data that other file is not arranged etc.
Therefore, be necessary to strengthen the protection of dropping of portable hard drive when work.
Summary of the invention
Therefore; the object of the present invention is to provide a kind of hard-disc drop protection method; it is detected the motion of hard disk by inductor; when hard disk drops; cut off hard disk control circuit and hard disk power supply; force the magnetic head of hard disk to get back to position of readiness, bump against video disc, thereby prevent that hard disk is damaged to avoid magnetic head.
For being implemented in above-mentioned purpose, the invention provides a kind of hard-disc drop protection method, the induced signal that provides hard disk to move by inductor is provided; But judge according to the intensity of induced signal whether hard disk falls to by the induced signal processor and set bearing strength; If cut off hard disk control circuit and hard disk power supply; If not, keep hard disk control circuit and hard disk power supply.
Described hard-disc drop protection method; wherein; judge according to the intensity of induced signal but but whether hard disk falls to the step that sets bearing strength and comprise shake intensity and the drop height setting one default bearing strength value that can bear according to hard disk by the induced signal processor; but and the induced signal intensity that inductor is sent here with should default bearing strength value compare, thereby but judge whether hard disk falls to and set bearing strength.
Described hard-disc drop protection method, wherein, the step of cutting off hard disk control circuit and hard disk power supply comprises induced signal output signal of processor cut-out hard disk control circuit and hard disk power supply, forces the magnetic head of hard disk to get back to position of readiness.
Described hard-disc drop protection method wherein, keeps the step of hard disk control circuit and hard disk power supply further to comprise: but in induced signal intensity during much smaller than this default bearing strength value, the induced signal processor is not done further processing to this induced signal; And when but induced signal intensity is slightly less than this default bearing strength value, then show that by graphoscope warning prompt is to remind the user.
Hard-disc drop protection method of the present invention is detected the motion of hard disk by inductor; when hard disk drops, cut off hard disk control circuit and hard disk power supply, force the magnetic head of hard disk to get back to position of readiness; can effectively avoid magnetic head to bump against video disc, thereby prevent that hard disk is damaged.
In order further to understand feature of the present invention and technology contents, see also following about detailed description of the present invention and accompanying drawing, yet appended graphic only provide with reference to and the explanation usefulness, be not to be used for the present invention is limited.
Brief description of drawings
Below in conjunction with accompanying drawing,, will make technical scheme of the present invention and other beneficial effects apparent by the specific embodiment of the present invention is described in detail.
In the accompanying drawing,
Fig. 1 is the process flow diagram of hard-disc drop protection method of the present invention.
Embodiment
For further setting forth technological means and the effect that the present invention takes for the predetermined purpose of realization, see also following about detailed description of the present invention and accompanying drawing, believe purpose of the present invention, feature and characteristics, should obtain thus going deep into and concrete understanding, yet accompanying drawing only provides reference and explanation usefulness, is not to be used for the present invention is limited.
Consult Fig. 1, the induced signal that provides hard disk to move by inductor is provided hard-disc drop protection method of the present invention; But judge according to the intensity of induced signal whether hard disk falls to by the induced signal processor and set bearing strength; If cut off hard disk control circuit and hard disk power supply; If not, keep hard disk control circuit and hard disk power supply.
Judge according to the intensity of induced signal but but whether hard disk falls to the step that sets bearing strength and comprise shake intensity and the drop height setting one default bearing strength value that can bear according to hard disk by the induced signal processor, but and the induced signal intensity that inductor is sent here with should default bearing strength value compare, thereby but judge whether hard disk falls to and set bearing strength.
The step of cutting off hard disk control circuit and hard disk power supply comprises induced signal output signal of processor cut-out hard disk control circuit and hard disk power supply, forces the magnetic head of hard disk to get back to position of readiness.
Keep the step of hard disk control circuit and hard disk power supply, also can further comprise: but in induced signal intensity during much smaller than this default bearing strength value, the induced signal processor is not done further processing to this induced signal; And when but induced signal intensity is slightly less than this default bearing strength value, then can show that warning prompt is to remind the user by graphoscope.
Hard-disc drop protection method of the present invention is detected the motion of hard disk by inductor; when hard disk drops, cut off hard disk control circuit and hard disk power supply, force the magnetic head of hard disk to get back to position of readiness; can effectively avoid magnetic head to bump against video disc, thereby prevent that hard disk is damaged.
The above; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to technical scheme of the present invention and technical conceive, and all these changes and distortion all should belong to the protection domain of accompanying Claim of the present invention.
