Embodiment
For let above-mentioned and other purposes of the present invention, feature and advantage can be more obviously understandable, the hereinafter spy enumerates preferred embodiment, and cooperates appended accompanying drawing, elaborates as follows.
Please earlier with reference to figure 1, the protection system 1 of hard disc data of the present invention is arranged in the portable electron device 2.As shown in Figure 1, portable electron device 2 comprises power supply device 21 and hard disk 22, and wherein the protection system 1 of hard disc data is arranged between power supply device 21 and the hard disk 22.Power supply device 21 is in order to provide working power to each the assembly running in the portable electron device 2, and wherein working power comprises the hard disk working power, and the hard disk working power supplies hard disk 22 runnings.The protection system 1 of hard disc data electrically connects with power supply device 21 and hard disk 22 respectively, and the protection system 1 of hard disc data comprises power switching module 11, standby power supply module 12, power supply detection module 13 and controller 14.In one embodiment of this invention, power switching module 11, standby power supply module 12, power supply detection module 13 are arranged on the motherboard (figure does not show) of portable electron device 2 with the form of circuit, but the present invention is not as limit; For instance, power switching module 11, standby power supply module 12, power supply detection module 13 also can be software, hardware or firmware.In one embodiment of this invention, portable electron device 2 is a notebook computer, and hard disk 22 is 2.5 inches hard disks that meet the SATA interface, but the present invention is not as limit; For instance, portable electron device 2 also can be flat computer or other have the portable electron device of hard disk.
Whether power switching module 11 transfers to hard disk 22 in order to control hard disk working power, and in one embodiment of this invention, power switching module 11 is field effect transistor (FET) switch, but the present invention is not as limit.In one embodiment of this invention, standby power supply module 12 comprises at least one electric capacity, just often can charge in the supply of hard disk working power.In a preferred embodiment of the present invention, standby power supply module 12 by two electric capacitys be 470 μ F (Farad) and three electric capacitys by 330 μ F parallelly connected electric capacity constituted, but the present invention is not as limit; In one embodiment of this invention, the electric capacity of above-mentioned power module 12 combination under the providing of no additional power supply, can provide hard disk 22 about 2 seconds running time again.In one embodiment of this invention, power supply detection module 13 is made up of voltage comparator and logic determines circuit, but the present invention is not as limit.Controller 14 is through connecting interface (such as SATA interface) transfer control instruction to the hard disk 22 of hard disk 22; In one embodiment of this invention; Controller 14 is embedded controller (embedded controller); Controller 14 is arranged on the motherboard of portable electron device 2 with the form of chip, but the present invention is not as limit.
Be example promptly below with the protection system 1 of hard disc data of the present invention shown in Figure 1; Specify each step of the guard method of hard disc data of the present invention; But it is noted that; As long as can reach the object of the invention, method of the present invention is not exceeded with the protection system 1 that is applied in hard disc data shown in Figure 1.
As shown in Figure 2, step S71 is at first carried out in the guard method of hard disc data of the present invention: receive the hard disk working power.
In one embodiment of this invention, the hard disk working power is provided the usefulness that operates to hard disk 22 by power supply device 21.
The present invention then carries out step S72: judge whether the hard disk working power is normal.
In one embodiment of this invention, hard disk 22 has WV, and WV is 5V, but the present invention is not as limit; For instance, the WV of hard disk 22 also can be 12V.
Under normal circumstances, the hard disk working power 5V that provides of power supply device 21 is to hard disk 22; In one embodiment of this invention; The voltage that detects the hard disk working powers when power supply detection module 13 and this WV in fact gap surpass this WV 5% the time (voltage of hard disk working power is greater than 5.25V or less than 4.75V), then power supply detection module 13 judgement hard disk working powers are undesired.
When power supply detection module 13 judged that the hard disk working power is undesired, then the present invention carried out step S73: cut-out hard disk working power is to the hard disk power supply and provide standby power supply that hard disk is supplied power.
In one embodiment of this invention; If power supply detection module 13 judges that the hard disk working power is undesired; Power supply detection module 13 control power switching modules 11 cut off the annexation of hard disk working powers and hard disk 22, and change by 12 pairs of hard disks 22 of standby power supply module and provide standby power supply to supply power.Embodiment about standby power supply module 12 is explained at the foregoing description, so do not give unnecessary details at this.
The present invention carries out step S74 at last: after the control hard disk is accomplished the access of hard disc data, close the running of hard disk.
In one embodiment of this invention; Hard disk 22 is when changing by the power supply of the standby power supply of standby power supply module 12; Power supply detection module 13 synchronization notice controllers 14 hard disk working powers are undesired, and controller 14 transfer control instructions are to hard disk 22, and control hard disk 22 (for example writes the data of the buffer zone of hard disk the disc of hard disk) behind the access operation of accomplishing existing hard disc data; Close the running of hard disk 22; The read/write head of hard disk 22 can be playbacked, prevent the loss of hard disc data by this, or even the damage of hard disk 22 intrawares.
To sum up institute is old, and no matter the present invention everywhere all shows it totally different in the characteristic of known technology with regard to purpose, means and effect, earnestly asks the auditor to perceive, and grants quasi patent early, makes Jiahui society, and the true feeling moral just.Only it should be noted that above-mentioned many embodiment give an example for the ease of explanation, the present invention's interest field required for protection should be as the criterion so that the scope of claims is said naturally, but not only limits to the foregoing description.
