Abstract
A power-off protector for computer data is used to protect computer data automaticlaly in case of power-off. A chargeable battery is used to power the computer so that the computer system can back up the present state in hard disc automatically. After the power supply restores to its normal state, the computer system can stores the state just before power-off with the protected data.
Description
The present invention relates to a kind of protective device of computer data, can be applicable to various data processing equipments, protect the device of pc data during particularly a kind of the outage automatically.
Computing machine has become indispensable instrument in the daily life, because it not only can provide the working clan help on working, file editor or drawing, program design etc., also can use for general individual, playing computer game, surfing the Net, see a film or listen to the music or the like, can be described as indispensable instrument on a kind of quite general life appliance and the public place of entertainment no matter be.
General desktop PC, unless install uninterrupted power supply (ups) Unity additional, otherwise in a single day powering-off state takes place, the data of handling all can disappear in a flash, and accumulate over a long period, and can cause huge injury to the part of computing machine.Uninterrupted power source has the function of temporary transient power supply when electric power takes place by undesired the interruption.Need uninterrupted power source to keep the stable of electric current especially in the area of electric current less stable, its maximum benefit is to be unlikely and has little time to store the data of keying in, and makes data to keep consistency, and the expensive main frame of protection.Usually after outage, uninterrupted power source can also be kept the power-on time more than ten minutes, so that perform the action of storage.
Generally speaking, uninterrupted power source also can't be powered the time for a long time, but has been enough to allow the user deal carefully with or storage data; But uninterrupted power source must additionally be bought and be not cheap, and this expense is not that common people are ready to bear.
Fundamental purpose of the present invention provides a kind of power-off protection apparatus of computer data, can protect computer data automatically in when outage, makes it can be because of outage does not cause loss, and cost is quite cheap.
Power-off protection apparatus according to computer data disclosed by the invention utilizes a rechargeable battery; by power supply unit it is charged at ordinary times; and power supply state through a detecting unit detection computations machine; when computer circuit breaking; the notice rechargeable battery is to computer power supply; and storing recovery unit notice system for computer by one is equipped with present shape on hard disk automatically; when the electric power regular supply; when reopening system; read the state backup that stores in the hard disk by storing the recovery unit reporting system again; thereby system recovery to the preceding state of outage, is reached the purpose of protection computer data.
For making purpose of the present invention, architectural feature and function thereof there are further understanding, describe in detail below in conjunction with accompanying drawing:
Fig. 1 is a synoptic diagram of the present invention; And
Fig. 2 is a process flow diagram of the present invention.
Power-off protection apparatus according to computer data disclosed by the invention, as shown in Figure 1, utilize a rechargeable battery 12, electric power supply at ordinary times just often, interfaces such as system's 14 process buses are (such as the I2C bus, or the like), join with electric supply installation 12, judge whether its charging (to be charged by 11 pairs of rechargeable batteries of power supply unit 12 at ordinary times certainly by power supply unit 11, when electric power is saturated, system 14 learns through interfaces such as buses and notifies power supply unit 11 to stop its charging), through a detecting unit 16, the power supply state that the detection computations machine is current; When computer circuit breaking, notice rechargeable battery 12 pairs of computer power supplies store recovery unit 17 and can learn also and be off-position at present that the state that notice computer system 14 automatically will be present backs up at hard disk 15 (SuspendTo Disk through detecting unit 16; STD); When learning that through detecting unit 16 electric power recovers to supply once more; when once more system 14 being started; store recovery unit 17 and can read the state Backup Data that stores in the hard disk 15 by reporting system 14, system 14 is returned to the preceding state of outage automatically, and then reach the purpose of protection computer data.
Because during outage; the action of system's 14 states backup; be " to handle " (backuping to hard disk) automatically by system 14; so BACKUP TIME can be quite short, and notify battery 12 only to need, and do not need screen 13 and peripherals 10 etc. is powered system 14 and hard disk 15 power supplies; so the capacity of electric supply installation 12 does not need very big; can reduce cost significantly, that is to say and utilize cheap cost, can reach the purpose of the protection computer data identical with uninterrupted power source.
The actual situation of carrying out, as shown in Figure 2, electric power supply is normal at ordinary times, computing machine can just be operated, and when detecting unit 16 detects system's 14 outages (step 20), through 12 discharges (step 21) of detecting unit 16 notice electric power systems, just to system 14 and hard disk 15 power supplies, and, the state of present system 14 is stored to hard disk 15 (step 22) again through storing recovery unit 17 reporting systems 14; When storing recovery unit 17 and detect the normal and system 14 of power recovery and start once more (step 23) through detecting units 16; store recovery unit 17 reporting systems 14 and read the state backup that stores in the hard disk 15; thereby system 14 can be returned to the state (step 24) before the outage; so; can be through the very little rechargeable battery 12 of a capacity; equal to utilize the original protection system 14 of very little one-tenth, can not disappear because of abnormal outage causes user's computer data.
The situation of outage when taking place in the power-off protection apparatus of computer data of the present invention; automatically the state with system is stored in the hard disk; can power supply power recover just often to recover its state; avoid the disappearance or the destruction of computer data; and only utilize a rechargeable battery to realize the effect of computer data protection, reduce cost significantly.
The above for the preferred embodiment among the present invention, is not to be used for limiting practical range of the present invention only; Be all equivalent changes and improvements of doing by claims of the present invention, all cover for claim of the present invention.
