The present invention protects hard disk to avoid the method for shock damage, comprises the steps:
1. monitor hard disk and be subjected to earthquake situations condition record;
2. check that the hard disk that is monitored is subjected to earthquake situations condition record;
3. be subjected to earthquake situations condition record according to the check hard disk that monitors, the control hard disk rotates or stall.
The present invention protects hard disk to avoid the method for shock damage, wherein:
The hard disk that described step monitors in 1. is subjected to earthquake situations condition record, when hard disk remains static, is that hard disk is shaken historical record in a period of time; When hard disk is in rotary state, be hard disk current be subjected to earthquake situations condition record.
Described step checks that the hard disk that is monitored is subjected to earthquake situations condition record in 2., when hard disk remains static, is to be checked by the moment of stationary state before rotary state changes that at hard disk the hard disk that monitored is shaken record in rotation moment in for the previous period; When hard disk is in rotary state, be check the hard disk that monitored current shaken record;
Described step 3. in the control hard disk rotate or stall, be that the hard disk that control will be rotated continues the maintenance stationary state, perhaps controls the hard disk stall of rotating, and gives a warning when the check hard disk that monitors is subjected to the earthquake situations condition to be recorded as vibrations to occur; When the check hard disk that monitors was subjected to the earthquake situations condition to be recorded as shockproof the appearance, control remained static and the hard disk that should rotate is transformed into and is in rotary state, and perhaps the hard disk that rotating of control is rotated further.
The present invention protects hard disk to avoid the method for shock damage, and wherein said a period of time was 10 seconds.
The described protection hard disk of the invention process is avoided the device of the method for shock damage; the X-axis that it is included in three directions monitorings of X, Y and Z hard disk shock conditions is quickened inductor, Y-axis and is quickened inductor, Z axle and quicken inductor, three A/D converters and microcontroller; described three acceleration inductors wherein are electrically connected with an A/D converter respectively, and three A/D converters are electrically connected with microcontroller again.
The present invention protects hard disk to avoid the method for shock damage and the advantage of device is: easy, effective, reliable; be specially adapted to the portable hard disk rotation reading of data of leaning on and come among the cutting apparatus of system works, the most suitable with the digital camera of MP3 player and band hard disk especially.Because the time that the hard disk of these two kinds of devices rotates is short, the static time is long, be convenient to quicken inductor and monitor its state in a period of time, and they is generally all carried, no matter be placed in pocket, the bag or in hand held, its probability that is given a shock is all bigger.But, using under the situation of the present invention, when hard disk is static, monitor the historical record that it is shaken, occur if any vibrations, then just can not change, and give a warning during this rotation; When hard disk rotated, the monitoring current state occurred if any vibrations, then hard disk stall at once, and give a warning.Therefore, can be being reduced to minimum level owing to shake the infringement that brings to hard disk.
Description of drawings is described further device of the present invention below in conjunction with accompanying drawing.
Fig. 1 is the connection block diagram of the ingredient of device of the present invention.
Embodiment as shown in Figure 1, device of the present invention comprises that X-axis quickens inductor, Y-axis and quicken inductor, Z axle and quicken inductor, three A/D converters and microcontroller, wherein said three acceleration inductors are electrically connected respectively with three A/D converters, and three A/D converters are electrically connected with microcontroller again.
When using device of the present invention, described three are quickened inductors and want the hard disk of protective device to carry out mechanical connection in X-axis, Y-axis and three directions of Z axle, microcontroller is electrically connected with hard disk.Like this, when hard disk was given a shock, its speed can change, by described acceleration inductor, the monitoring hard disk is subjected to the earthquake situations condition X, Y and three directions of Z axle, passes through A/D converter then, the analog signal conversion of velocity variations is become digital signal, pass to microcontroller again and handle.Microcontroller sends rotation or stall that different signals is controlled hard disk according to different situations.According to actual user mode, can monitor hard disk in X, Y and any one direction of Z axle, both direction or three directions is subjected to the earthquake situations condition arbitrarily.
