Make very simple, be very beneficial for the on-site maintenance of embedded system.
In a preferred embodiment of the invention, as shown in figure 4, being the maintenance system of embedded system of the embodiment of the present invention
Another structural representation, in the present embodiment, add the identification verification function for movable storage device 101, improve
The security of embedded system maintenance work.In the present embodiment, identity is also stored with the movable storage device 101 to test
Key is demonstrate,proved, reference picture 4, is also stored with identity authenticating unit 104 in the bootstrap 4, the identity authenticating unit 104 is set
For after the service mode opening unit 102 opens the service mode, according to the authentication key and the identity
The key that authentication unit 104 stores, judges whether the identity of the movable storage device 101 is legal.The software writes with a brush dipped in Chinese ink unit
103 in the case of it is determined that the identity of the movable storage device 101 is legal, and the new procedures are write with a brush dipped in Chinese ink into embedded system
In.
In the present embodiment, it is determined that opening service mode and carrying out between software writes with a brush dipped in Chinese ink, adding movable storage device
101 identity authenticating unit 104, maintenance workers are carried out so as to avoid after the movable storage device of unauthorized connects embedded system
Make, add the security of maintenance work.Specifically, identity authenticating unit 104 judges that the identity in movable storage device 101 is tested
Whether card key and the key that the identity authenticating unit 104 itself stores are consistent, and in the case of it is determined that both are consistent, it is determined that
The identity of movable storage device 101 is legal.Especially, the identity authenticating unit 104 judges the authentication key and institute
Whether identical state key, and it is determined that in the case of both identicals, the identity for determining movable storage device 101 is legal.
In a preferred embodiment of the invention, as shown in figure 5, being that software writes with a brush dipped in Chinese ink unit 103 in the embodiment of the present invention
Structural representation, the software, which writes with a brush dipped in Chinese ink unit 103, includes Maintenance Significant Items determining unit 201, file system maintenance unit 202, behaviour
Make system maintenance unit 203 and upper level applications maintenance unit 204.
Specifically, the Maintenance Significant Items determining unit 201, it is arranged to obtain the Maintenance Significant Items of user's selection.Here, user
The maintenance interface typically shown by touch display screen, dimension corresponding to this maintenance work is selected in Maintenance Significant Items drop-down menu
Shield project, in view of the object of maintenance work includes file system 2, operating system 3 and upper level applications 1, so specific dimension
Shield project includes following three kinds：File system maintenance, to situation about should be safeguarded to file system 2；Operating system is safeguarded, right
Situation about operating system 3 should be safeguarded；Upper level applications are safeguarded, to the feelings that should be safeguarded to upper level applications 1
Condition.
The file system maintenance unit 202, it is arranged to it is determined that the Maintenance Significant Items are the situation of file system maintenance
Under, judge whether include file system new procedures in the new procedures, and include the file system in the new procedures
In the case of new procedures, the file system new procedures are write with a brush dipped in Chinese ink in embedded system.Especially, file system maintenance unit
202 after judging that movable storage device 101 includes file system new procedures, it is also necessary to determines whether that this document system is new
Whether program is correct, and embedded system is write with a brush dipped in Chinese ink after confirming that file system new procedures are correct, then by this document system new procedures
In, further increase the security of maintenance work.The no correctly method of above-mentioned judgement file system new procedures is needed according to tool
The implementation process of body specifically determines, therefore no longer carries out expansion explanation herein.
The operating system maintenance unit 203, it is arranged to it is determined that the Maintenance Significant Items are the situation that operating system is safeguarded
Under, judge whether include operating system new procedures in the new procedures, and include the operating system in the new procedures
In the case of new procedures, the operating system new procedures are write with a brush dipped in Chinese ink in embedded system.Especially, operating system maintenance unit
203 after judging that movable storage device 101 includes operating system new procedures, it is also necessary to determines whether that the operating system is new
Whether program is correct, and embedded system is write with a brush dipped in Chinese ink after confirming that operating system new procedures are correct, then by the operating system new procedures
In, further increase the security of maintenance work.It is above-mentioned to judge that the whether correct method of operating system new procedures needs basis
Specific implementation process specifically determines, therefore no longer carries out expansion explanation herein.
The upper level applications maintenance unit 204, it is arranged to it is determined that the Maintenance Significant Items are tieed up for upper level applications
In the case of shield, judge whether include upper level applications new procedures in the new procedures, and include in the new procedures
In the case of the upper level applications new procedures, the upper level applications new procedures are write with a brush dipped in Chinese ink in embedded system.Especially
Ground, upper level applications maintenance unit 204 after judging that movable storage device 101 includes upper level applications new procedures,
