Abstract

This invention is a hard disk protection system by detecting three dimensional moving status of the disk to judge for shut down. The system includes a detecting module to check disk's three dimensional moving distance, a control module to calculate the three dimensional moving distance for indication of whether to shut down, a process module to shut down upon receiving the signal. Without an out linked simulating/digital exchanger, the system makes it available for fast judgment of dangerous status of hard disk and automatically shut down for protection.

Description

Hardisk protecting system

Technical field

The present invention relates to a kind of protection system, particularly relate to a kind of Hardisk protecting system.

Background technology

The fast development of science and technology makes notebook computer popularize gradually, for busy modern, carries notebook computer and can assist us on the automobile, carry out the work at any time on the train even on the aircraft, and is very convenient.Yet, when on car, using, often, cause the magnetic head of hard disk ceaselessly to beat magnetic track, to such an extent as to damage hard disk because road jolts.For the better protection hard disk, research and development one cover protection mechanism is very urgent.

Please refer to Fig. 1, be the prior art system Organization Chart, all is to utilize three-dimensional analog signal at present, converts digital signal earlier to, and then utilizes bus notice control chip with the action of control hard disk.

At first, detect the acceleration of hard disk 150 when moving by detecting device 110, this moment, detected signal was a simulating signal.Analog signal conversion by analog/digital converter self-detector 110 in 120 future becomes digital signal then.Afterwards, the digital signal after the conversion is delivered to controller 130, judge by controller 130 computings whether hard disk 150 is in a dangerous vibrating state, promptly whether arrive essential shut-down operation otherwise the critical point of damage.If be judged as shut-down operation, then controller 130 can send a look-at-me and give interrupter 140, activating interrupter 140, and stops the continuation operation of hard disk 150.

Yet in the prior art, what comprise is an external analog/digital converter 120, and it is in order to become analog signal conversion digital signal to carry out digital operation.If can directly utilize the simulating signal that receives to do computing, then more can accelerate discriminating speed, in time to stop the hard disk operation, avoid hard disk injured.

Summary of the invention

Technical problem underlying to be solved by this invention is to provide a kind of Hardisk protecting system; it does not need an external analog/digital converter, and directly utilizes simulating signal notice control module, just can determine whether to stop hard disk operation; with rapid discriminating precarious position, the protection hard disk avoids damaging.

For finishing above-mentioned purpose, the invention discloses a kind of Hardisk protecting system, it interrupts the read operation of hard disk by detecting the three-dimensional mobile status of hard disk.This Hardisk protecting system includes:

One detection module in order to detecting X-axis amount of movement, y-axis shift momentum and the Z axle amount of movement of hard disk, rocks or during mobile status, just can detect and learn three-dimensional amount of movement when hard disk is in;

Whether one control module in order to the computing through an algorithm of X-axis amount of movement, y-axis shift momentum and Z axle amount of movement, sends a look-at-me with decision.By the amount of movement of three of computings, can learn whether hard disk is in a utmost point vibrating state.When needing shut-down operation with the protection hard disk, control module just can send look-at-me to processing module; And

One processing module is in order to receive the look-at-me that control module is sent, to interrupt the read operation of hard disk.

The present invention does not need an external analog/digital converter, but directly three-dimensional analog signal is converted to digital signal, sends control module again to and does computing, and control module just can be learnt the state of hard disk from row operation.Promptly judge hard disk more rapidly and whether be in and acutely rock etc. in the unsafe condition, and in time interrupt hard disk operation to guarantee safety.For providing, the user uses by bus or antidetonation service during the accidental fall notebook.

Below in embodiment, be described in detail detailed features of the present invention and advantage, its content is enough to make any those of ordinary skill in the art to understand technology contents of the present invention and implements according to this, and according to content, claim and the accompanying drawing that this instructions provided, any those of ordinary skill in the art can understand purpose and the advantage that the present invention is correlated with easily.

Embodiment

For purpose of the present invention, structure, feature and function thereof are had further understanding, now cooperate embodiment to be described in detail as follows.More than about the explanation of the explanation of content of the present invention and following embodiment in order to demonstration with explain principle of the present invention, and provide patent claim of the present invention further explained.

See also Fig. 2, be Hardisk protecting system Organization Chart of the present invention.By detecting three mobile statuss of hard disk 150, through computing, judge whether to interrupt the action of reading of this hard disk 150, this system includes a detection module 210, a control module 220 and a processing module 230.

Detection module 210, in order to detect X-axis amount of movement, y-axis shift momentum and the Z axle amount of movement of hard disk 150, the unit of these three amount of movements is volt (voltage), and detection module 210 sends this three axis signal to control module 220, and transmits with analog signaling.

Control module 220, three simulating signals that reception is transmitted by detection module 210 are in control module 220 inside, after this three simulating signals computing through a conversion and an algorithm, whether the value of rocking of judging hard disk 150 has reached interruption hard disk critical value, is then to send look-at-me.

Processing module 230 is in order to receive the look-at-me that control module 220 is sent, to interrupt the read operation of hard disk 150.

Wherein, also include an analog/digital conversion unit 222, a computing unit 224 and a judging unit 226 in the control module 220.

Analog/digital conversion unit 222 is in order to be converted to digital signal with X-axis amount of movement, y-axis shift momentum and Z axle amount of movement.

Computing unit 224, be connected with analog/digital conversion unit 222, calculate corresponding X-axis gravity value, Y-axis gravity value and Z axle gravity value in order to X-axis amount of movement, y-axis shift momentum and Z axle amount of movement, or calculate corresponding each accekeration digital signal.

Judging unit 226, be connected with computing unit 224, in order to according to algorithm, whether judgement one has reached and has interrupted the hard disk critical value, promptly according to the resulting judgment value of algorithm according to the judgment value that X-axis gravity value, Y-axis gravity value and Z axle gravity value are calculated, whether decision stops the hard disk operation, when judgment value reaches interruption hard disk critical value, promptly send look-at-me to processing module 230, this interrupts hard disk critical value and has been pre-set in judging unit 226 inside.

This system also is provided with a disk interface 240 between processing module 230 and hard disk 150, out of service with notice hard disk 150 in order to transmit interrupting information, is a serial hard-disk interface (SATA) or a parallel hard-disk interface (PATA).

Though the present invention with aforesaid embodiment openly as above, it is not in order to limit the present invention.Without departing from the spirit and scope of the present invention, change of being made and modification all belong to scope of patent protection of the present invention.See also appending claims about the protection domain that the present invention defined.
