Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.
Refer to Fig. 2, the schematic flow sheet of its a kind of system software backup and restore method provided for the preferred embodiment of the present invention.
As shown in Figure 2, after os starting (step S20), automatically starting backup detects boot (step S21) and reduction detects boot (step S26).The operating system of the present embodiment can be mounted in the operating system in the microprocessor module of embedded system, and be such as arranged on the Windows CE operating system in the arm processor module of embedded LED display screen control system, this is not restricted in the present invention.Preferably, after os starting, backup detects boot and detects boot startup prior to reduction.
Next, on the one hand, backup detection boot optionally carries out step S22, S23, S24 and S25 upon actuation.Be specially: backup detects boot and carries out digital finger-print verification (step S22) to the file that intended application software comprises, the digital finger-print file of the file that the intended application software that such as acquisition is stored in [the normal district] of storer comprises, and the digital finger-print that resolution digital file fingerprint stores in advance to obtain each file, the digital finger-print of each file in the file that the intended application software that calculating is stored in [the normal district] of storer comprises, and each digital finger-print of the digital finger-print of each file calculated and storage in advance is compared, judge digital finger-print verification whether failed (step S23) whereby, if had, file is few or digital finger-print contrast is not identical, then think that the file that the intended application software in [normal district] comprises exists loss or damages, also namely digital finger-print verifies unsuccessfully, otherwise, judge digital finger-print verification succeeds.If judge digital finger-print verification succeeds, then represent that backup detects boot and completes backup detection guiding function; If judge, digital finger-print verifies unsuccessfully, then start backup copy, the file that the intended application software of [backup area] of copy memories comprises is prepared to [reducing zone] (step S24) of storer for the restoring operation of succeeding target application software, and after copy completes, backup detects boot makes operating system restart (step S25) such as autoboot, so far completes backup and detects guiding function.It is worth mentioning that at this, making operating system restart reason is herein due to when backing up detection boot and starting, intended application software may run, if intended application software is in running status during reduction, may causes go back primary failure during reduction owing to taking.In addition, it should be noted that, [the normal district] of the present embodiment refers to the catalogue that intended application software normally runs, and [backup area] refers to the file directory of backup target application software, and [reducing zone] refers to the file directory of restore target application software; Above-mentioned storer is such as the nonvolatile memories such as flash memory; Above-mentioned digital finger-print verification is such as MD5 code check, can certainly be that other digital finger-print based on file content verifies; Above-mentioned intended application software is such as the LED display control software design being installed on embedded OS, but the present invention is not as limit.
On the other hand, reduction detection boot optionally carries out step S27, S28 and S29 upon actuation.Be specially: no matter be after the os starting of step S20 or the operating system of step S25 are restarted, detect after boot starts in reduction and can check whether storer [reducing zone] exists the application software (step S27) needing reduction.If there is no need the application software of reducing, then directly start intended application software (step S29); Such as, such as, otherwise if there is the application software needing reduction, being that [reducing zone] exists intended application software to be restored, then carrying out application software restoring operation (step S28), is carry out restoring operation to intended application software.After completing application software restoring operation, carry out step S29, also namely start intended application software.After startup intended application software, reduction detects boot and namely completes reduction detection guiding function.
In the above-described embodiments, the detection that backup detected and reduce is divided into two software programs and realizes, also likely damage, so one of them can not be relied on completely to complete startup and the detection of whole software because be backed up detection boot with reduction detection boot; And, backup-and-restore is realized respectively by using two software programs, reduction can be made to detect boot can automatically close after completing its work, to reduce the damage that long-play may cause, and the program making backup detect boot is run simple, the associated documents of access are less, to reduce the possibility of damage.
In addition, it is worth mentioning that, with the microprocessor module of embedded system as an example, it generally includes hardware layer, OEM (Original Equipment Manufacturer, original equipment manufacturer) layer, operating system layer and application layer, and above-mentioned backup detects boot and reduction detection boot belongs to application layer software.
Refer to Fig. 3, it is the module diagram of a kind of system software backup and reduction device of the preferred embodiment of the present invention.As shown in Figure 3, the microprocessor module that system software backup and reduction device 30 is such as applied to embedded system is as the arm processor module etc. of embedded LED display screen control system, and it comprises: backup detects bootstrap module 31 and reduction detects bootstrap module 33.In the present embodiment, backup detects bootstrap module 31 and reduction and detects bootstrap module 33 and can backup as shown in Figure 2 detect boot and reduction and detect boot and realize respectively, each step that its concrete function can detect boot with reference to aforesaid backup and reduce performed by detection boot, does not repeat them here.
It is worth mentioning that in addition, the system software backup and restore method of the previous embodiment of the above embodiment of the present invention and device are not limited to and are applied to embedded LED display screen control system, also LCD display control system etc. can be applied to, even be not confined to be applied to embedded system, can be applied to the equipment of the miniature tape operation systems such as microcomputer yet.
In sum, the embodiment of the present invention can make system reboot when application software fault appears in the system of detecting, carry out self-recoverage and without the need to depot repair, therefore can reduce maintenance cost and maintenance cycle, also can improve the stability of system such as embedded LED display screen control system.
So far, apply specific case herein and set forth the principle of system software backup and restore method of the present invention and device and embodiment, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping; Meanwhile, for one of ordinary skill in the art, according to thought of the present invention; all will change in specific embodiments and applications; in sum, this description should not be construed as limitation of the present invention, and protection scope of the present invention should be as the criterion with appended claim.
