Description
Technical field
The invention relates to a kind of protection mechanism of electronic installation, particularly a kind of multiple protection method of boot program of the portable electric device that is applied to have storage element.
Background technology
Traditional being applied to hard disk is that the start process flow diagram of device of main storage data medium is referring to Fig. 1, when start, carry out the boot-strap program code (boot code) (step 110) in the flash memory (Flash), so that the operating system kernel software (T-kernel) in the hard disk is loaded random access memory (Random Access Memory; RAM) (step 120) follows executive operating system kernel software (step 130), after the operating system kernel software startup is finished, again with (the Graphic User Interface of the graphic user interface in the hard disk as the usefulness of startup in; GUI) load in the random access memory (step 140), then carry out graphic user interface (step 150), after the execution graphic user interface is finished, just can again the application master routine in the hard disk be loaded in the random access memory (step 160), use master routine (step 170) to carry out, the application master routine is the program in order to display frame, and afterwards, the user just can see the key frame after the start.
Under normal circumstances, it is no problem to carry out in order, but in the start flow process, any part is made mistakes and maybe can't be finished, might cause serious consequence, for example: boot-strap program code is wrong, may be that flash memory is impaired or be subjected to factors such as electromagnetic interference (EMI), cause and complete operation system core software loading to move, or operating system kernel software leaves in the hard disk and damages, may be because hard disk is subjected to bump, undesired instant cut-off or other software and hardware factor, and can't start execution after making operating system kernel software load smoothly.
The archives that also might be graphic user interface (GUI) are damaged, cause reason identical with the possible cause that can't start the executive operating system kernel software, after starting smoothly, the system that makes but can't enter graphic user interface, also or use the master routine archives and damage, cause system successfully to enter graphic model, but can't carry out the application master routine, make the user can't see the key frame after the start.
Obdurability (robustness) for strengthening system; usually can add detection during the course and restart device; just in the total system operation; if find problematic words; just can over and over again repeat; not only in start process; after start, during the system normal operation too because systemic-function is numerous and complicated; have the state that pawns or can't successful execution unavoidably; detection and restart mechanism have been arranged, can restore at once, or damage control has been arrived minimum once said circumstances takes place; Windows operating system as Microsoft; if program mal takes place, then have only this program to carry out, can't feed through to the whole operation system; so, allow complete imperceptible this program of user pawn.
This mode, the degree of stability of strengthening system significantly, even work as machine, also can recover automatically under the most situation, can not allow the user that the sensation of working as machine is at the drop of a hat arranged, what but this mode was taken precautions against is the machine of working as of not knowing reason in the System Operation process, if archives itself are damaged or made mistakes, so constantly repeated priming mechanism can cause substantial risk.
Because hard disk is the mechanical type rotation, action constantly for a long time can produce high heat, if cause the startup failure because of the cause of archives itself, then system can think and is not activated success, and repeated attempt constantly, but each the trial all still is failure, therefore caused system to stop, hard disk is in user mode always, if the system of adding there is no outage mechanism, even the user perceives this situation and also can't shut down and allow system stop, must repeat the power drain up to system, the high temperature that this moment, hard disk produced might damage other assembly in hard disk itself or the device, if be placed in the confined space, also might because of overheated cause on fire or the blast, once also relevant for mobile phone be placed in the bag on fire without reason or the blast news report.
Even if all software and hardware actions are all normal, when power shortage, also can cause danger, when electric power supply is hanged down to a certain degree, (reset) can be restarted automatically in system, and the inreal pass plane mechanism that cuts off the power supply of existing design, so in case restart, then re-execute boot-strap program code, again carry out start-up routine, find just that after system start-up present power shortage repeats above-mentioned circulation again, because the electric current that the executive operating system kernel software is consumed is bigger, the power consumption of only carrying out boot-strap program code is less, so electric power is also enough in the time of very might carrying out boot-strap program code, yet in the time of will writing operating system kernel software in the random access memory, because the relation of power shortage, can't smoothly operating system kernel software be write, therefore when electric power is not enough, can cause the situation that constantly repeats to start shooting and can't close, because this moment, the electric power of battery was surplus few, was unlikely to allow system produce high heat constantly though constantly repeat start, can accelerate the rate of decay of device, and under some occasion, can produce legal liabilities, for example: when takeoff and landing, the electronic installation that the passenger carries constantly repeats start but can't be turned off, and will bring danger to flight.
Therefore the above incident institute probability of happening of carrying is all little, does not also cause enough attention of people, and still, above-mentioned incident is in case take place, and the consequence that is caused can be very serious, also might cause injury on life or the property to the user.
Summary of the invention
At the existing the problems referred to above of background technology; the objective of the invention is to; a kind of multiple protection method of boot program is provided; this method can be applied to portable electric device; this portable electric device is main storage data medium with a storage element; by the error count function and in advance with the not use zone of required program backup, with the purpose that hits pay dirk and repair and protect in hard disk.
In order to realize above-mentioned task, the technical solution that the present invention taked is as follows:
A kind of multiple protection method of boot program is applied to handheld electronic device, and this portable electric device system is main storage data medium with a storage element, stores the application master routine in order to display frame in storage element.

Embodiment
Below content in embodiment be enough to make any those skilled in the art of knowing to understand technology contents of the present invention and can implement, and according to technical scheme and the accompanying drawing that this instructions provides, any those skilled in the art of knowing can understand purpose and the advantage that the present invention is correlated with easily.
Consult Fig. 2 A; this figure is the multiple protection method process flow diagram of boot program of the present invention; be applied to portable electric device; as mobile phone; and portable electric device comprises a storage element at least; as hard disk, be used for wanting the storage data medium, and the application master routine in order to display frame need be deposited in storage element inside.
Therefore, the main step of method of the present invention has: at first, need the not use zone (step 202) of back-up application master routine to storage element, then, the user just carries out boot-strap program code (step 204) after pressing the start button, afterwards, with the present magnitude of voltage of portable electric device and default safe voltage value compare (step 205), and whether force the portable electric device outage according to comparison result decision, if do not need the portable electric device outage is not just connect executive operating system kernel software (step 210).
If when operating system kernel software is carried out failure, just need counting operation system core software to carry out unsuccessful number of times (step 211), according to the number of times of counting, whether decision forces the portable electric device outage; If the words that operating system kernel software runs succeeded, then carry out and use master routine (step 226), when the execution of application master routine is unsuccessful, need counting to use master routine and carry out unsuccessful number of times (step 227), and whether read the application master routine of backup so that cover original application master routine according to count results decision, yet, at the application master routine that reads backup with before covering original application master routine, the application master routine that needs counting to back up covers the number of times (step 231) of original application master routine, and according to counting the number of times that covers, whether force the portable electric device outage with decision, or the application master routine that reads backup is covering original application master routine, and continues to carry out and upgrade application master routine later.
See also Fig. 2 B again; this figure is the multiple protection method process flow diagram of another boot program of the present invention; be applied to equally with a storage element is the portable electric device of main storage data medium; this storage element can be hard disk; and in storage element inside except depositing application master routine in order to display frame; also deposit the graphic user interface in order to display frame, this graphic user interface was carried out before carrying out the application master routine.
At first, with the not use zone (step 202) of back-up application master routine to storage element, to back up the not use zone (step 203) of graphic user interface then to storage element, then, the user just carries out boot-strap program code (step 204) after pressing the start button, afterwards, with the present magnitude of voltage of portable electric device and default safe voltage value compare (step 205), and whether force the portable electric device outage according to comparison result decision, if do not need with portable electric device outage, just executive operating system kernel software (step 210).
When if operating system kernel software is carried out failure, just need counting operation system core software to carry out unsuccessful number of times (step 211), number of times according to counting, whether decision forces the portable electric device outage, if operating system kernel software runs succeeded, then carry out graphic user interface (step 216).
If graphic user interface is carried out unsuccessful words, just count graphic user interface and carry out unsuccessful number of times (step 217), whether the result according to counting reads the graphic user interface of backup to cover original graphic user interface with decision, yet, the graphic user interface of backup covers before the original graphic user interface, the graphic user interface that needs counting to back up covers the number of times (step 221) of original graphic user interface, and according to counting the number of times that covers, whether force the portable electric device outage with decision, or the graphic user interface that reads backup is covering original graphic user interface, and continues to carry out and upgrade graphic user interface later.
If graphic user interface runs succeeded, then continue to carry out and use master routine (step 226); When the execution of application master routine is unsuccessful, need counting to use master routine and carry out unsuccessful number of times (step 227), and whether read the application master routine of backup to cover original application master routine according to count results decision, yet, at the application master routine that reads backup with before covering original application master routine, the application master routine that needs counting to back up covers the number of times (step 231) of original application master routine, and according to counting the number of times that covers, whether force the portable electric device outage with decision, or the application master routine that reads backup is covering original application master routine, and continues to carry out and upgrade application master routine later.
Because the hard drive space of using is much older with respect to graphic user interface and application master routine at present; therefore can lose a little inappreciable space a little protects and repair mechanism; except that original program; in another catalogue or disk carry district, also put into same program; once original program start failure; then the program with another backup is copied to original block; and execution starts once more; like this; not only can double to ensure the fiduciary level of important archives; significantly promote to start successful probability, and have and to damage the function of archives reparation.
With reference to Fig. 2 C, Fig. 2 D and Fig. 2 E, these figure are first embodiment of the present invention process flow diagrams, as shown in the figure, at first, with the not use zone (step 202) of back-up application master routine to hard disk, then, the backup graphic user interface is to the not use zone (step 203) of storage element, then, the user just carries out boot-strap program code (step 204) after pressing the start button, afterwards, is the present magnitude of voltage that must compare portable electric device less than default safe voltage value? (step 206) is if the brownout of portable electric device, be that present magnitude of voltage is less than the safe voltage value, then force portable electric device outage (step 208), do not start down-stream, can solve light current repeated priming problem like this.
If the voltage of portable electric device also is not less than default safe voltage value, then can complete execution boot-strap program code, afterwards, follow executive operating system kernel software (step 210), need decision operation system core software to run succeeded then? (step 212), if operating system kernel software is carried out unsuccessful, need counting operation system core software to carry out unsuccessful number of times and reach first critical value? (step 214), this first critical value is default value, if operating system kernel software is carried out number of times no show still first critical value of failure, executive operating system kernel software (step 210) repeatedly so still, the number of times of carrying out failure up to operating system kernel software arrives first critical value, just force portable electric device outage (step 208), can solve the operating system kernel software error like this and the problem of repeated priming always.
If the words that operating system kernel software runs succeeded, basically, total system successfully is transferred to operating system kernel software and controls, then just carry out graphic user interface (step 216), similarly, need to judge that graphic user interface runs succeeded? (step 218), if graphic user interface is carried out unsuccessful words, need the counting graphic user interface to carry out the frequency of failure and reach second critical value? (step 220), this second critical value is suitable default value, if graphic user interface is carried out number of times no show still second critical value of failure, so still must carry out graphic user interface (step 216) repeatedly, the number of times of carrying out failure up to graphic user interface arrives second critical value, does the number of times that the graphic user interface that then needs counting to back up covers original graphic user interface reach the 3rd critical value? (step 222), the 3rd critical value is similarly suitable default value, if number of times no show still the 3rd critical value that covers, the graphic user interface that then reads backup is to cover original graphic user interface (step 224), after finishing, covering just continues to carry out graphic user interface (step 216), if the graphic user interface of backup covers the words that the number of times of original graphic user interface has reached the 3rd critical value, just force portable electric device outage (step 208), the graphic user interface of this expression backup may be wrong, solve like this that the graphic user interface archives damage and the problem of repeated priming again and again, not only quick-recovery also can be avoided endless repeated priming to prevent to work as machine soon.
If the words that graphic user interface runs succeeded, then carry out and use master routine (step 226), need to judge that using master routine runs succeeded? (step 228), if run succeeded, promptly finished whole boot program, need reach four critical value? if carry out the unsuccessful application master routine execution frequency of failure of then counting (step 230), the 4th critical value is similarly suitable and default value that assessed, do not reach the 4th critical value if use the master routine execution frequency of failure, then need continue to repeat application master routine (step 226), reached the 4th critical value if use the number of times of master routine execution failure, does the number of times that the application master routine that needs counting to back up covers original application master routine reach the 5th critical value? (step 232), if number of times no show still the 5th critical value that covers, the application master routine that then reads backup is to cover original application master routine (step 234), after finishing, covering just continues to carry out the application master routine (step 226) after covering, if the application master routine of backup covers the words that the number of times of the application master routine of original place has reached the 5th critical value, just force portable electric device outage (step 208), application master routine of this expression backup may be wrong, and above measure is to prevent the danger that constantly repeats to start shooting and cause.
Please refer to Fig. 3 A again; this figure is the thin portion of the multiple protection method of a boot program of the present invention process flow diagram; as shown in the figure; with the not use zone (step 202) of back-up application master routine to hard disk; and the backup graphic user interface to the not use zone (step 203) of storage element afterwards; also can back up boot-strap program code and operating system kernel software not use zone (step 2021), make that the obdurability of system significantly promotes, also reduce the risk that system can't start simultaneously to hard disk.
And carrying out boot-strap program code (step 204) afterwards, if carry out unsuccessful, need the counting boot-strap program code to carry out unsuccessful number of times (step 2040), whether the result according to counting reads the boot-strap program code of backup to cover original boot-strap program code with decision, yet, before the boot-strap program code of backup covers original boot-strap program code, the boot-strap program code that needs counting to back up covers the number of times (step 2045) of original boot-strap program code, and according to counting the number of times that covers, whether force the portable electric device outage with decision, or the boot-strap program code that reads backup is to cover original boot-strap program code, and continue execution and upgrade boot-strap program code later, if boot-strap program code runs succeeded, just continue with the present magnitude of voltage of portable electric device and default safe voltage value compare (step 205).
In addition, carry out unsuccessful number of times (step 211) afterwards at counting operation system core software, the operating system kernel software of count enable backup covers the number of times (step 2140) of original operating system kernel software, according to the number of times that covers, whether force the portable electric device outage with decision, or the operating system kernel software that reads backup is covering original operating system kernel software, and continues to carry out and upgrade operating system kernel software later.
Please continue to consult Fig. 3 B and Fig. 3 C, Fig. 3 B and Fig. 3 C are second embodiment of the present invention process flow diagram, as shown in the figure, with the not use zone (step 202) of back-up application master routine to hard disk, and the backup graphic user interface to the not use zone (step 203) of storage element afterwards, also can back up boot-strap program code and operating system kernel software not use zone (step 2021), make that the obdurability of system significantly promotes, also reduce the risk that system can't start simultaneously to hard disk.
After carrying out boot-strap program code (step 204), can do you judge earlier that boot-strap program code runs succeeded? (step 2041), if carry out unsuccessful, need the counting boot-strap program code to carry out the frequency of failure and reach the 6th critical value? (step 2042), if do not reach the words of the 6th critical value as yet, just continue to repeat boot-strap program code (step 204), if boot-strap program code is carried out the words that the number of times of failure has reached the 6th critical value, does the number of times that the boot-strap program code that then needs counting to back up covers original boot-strap program code reach the 7th critical value? (step 2043), if the words of number of times no show still the 7th critical value that covers, the boot-strap program code that then reads backup is to cover original boot-strap program code (step 2044), after finishing, covering just continues to carry out boot-strap program code (step 204), if the boot-strap program code of backup covers the words that the number of times of the boot-strap program code of original place has reached the 7th critical value, the program of expression backup also has problem, just forces portable electric device outage (step 208).
When the executive operating system kernel software, also can strengthen its obdurability, when if the unsuccessful number of times of counting operation system core software execution reaches first critical value, before forcing the portable electric device outage, does the number of times that the operating system kernel software that can count backup earlier covers original operating system kernel software reach the 8th critical value? (step 2141), if the words of number of times no show still the 8th critical value that covers, the operating system kernel software that then reads backup is to cover original operating system kernel software (step 2142), after finishing, covering just continues executive operating system kernel software (step 210), if the operating system kernel software of backup covers the words that the number of times of the operating system kernel software of original place has reached the 8th critical value, the operating system kernel software of expression backup also has problem, forces portable electric device outage (step 208) again.
At last; please refer to Fig. 4; this figure is the structural representation of portable electric device; to thoroughly solve the risk that may exist and to carry out multiple improvement simultaneously to the software and hardware of portable electric device; the improvement of software aspect is at the above-mentioned complete description that carried out; and at hardware aspect; the power-supply unit 410 of portable electric device 400; as the power source of battery as portable electric device 400; if can artificially manually substitute; or increase a gauge tap 420 that directly is connected with power-supply unit 410; be really to accomplish outage and nonvolatile stops or dormant state when portable electric device 400 outage; increase gauge tap and can reach strick precaution under the situation that the user discovers, hand-operated forced outage is with the function of protective device.
