In order to realize above-mentioned first purpose, the invention provides a kind of embedded system, comprise main system and standby system, described standby system is used for the upgrading part of backup operation system and application software, and starts auto-update and recovery embedded system to realize embedded system in the main system escalation process behind the generation fatal error.
According to described embedded system, described standby system can not be wiped free of.
According to described embedded system, described main system comprises operating system and application software, and can be wiped free of and upgrade.
In order to realize above-mentioned second purpose, the invention provides a kind of Implementation of Embedded System method, described embedded system comprises: main system and standby system, this method comprises as follows:
The upgrading part of A, standby system backup operation system and application software;
After in B, the main system escalation process fatal error taking place, start auto-update and the recovery embedded system of described standby system to realize embedded system.
According to described implementation method, described standby system can not be wiped free of.
According to described implementation method, described main system comprises operating system and application software, and can be wiped free of and upgrade.
In order to realize above-mentioned the 3rd purpose, the invention provides a kind of embedded device, comprise main system module and standby system module, described standby system module is used for the upgrading part of backup operation system and application software, and starts auto-update and recovery embedded system device to realize embedded system device in main system module upgrade process behind the generation fatal error.
According to described embedded device, backup operation system that described standby system module is stored and the upgrading of application software part can not be wiped free of.
According to described embedded device, described main system module comprises operating system and application software, and described operating system and application software can be wiped free of and upgrade.
The upgrading part of standby system backup operation system of the present invention and application software, and in the main system escalation process, take place to start behind the fatal error, can in the system recovery function after finishing the system upgrade failure, significantly reduce taking of storage space thus, and lower the embedded device cost greatly.
Description of drawings
Fig. 1 is embedded device construction module figure provided by the invention;
Fig. 2 is an Implementation of Embedded System method flow diagram provided by the invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Basic thought of the present invention is, the upgrading part of standby system backup operation system and application software, and in the main system escalation process, take place to start behind the fatal error with the auto-update of realizing embedded system and recover embedded system.
Embedded device 100 provided by the invention comprises main system module 101 and standby system module 102 as shown in Figure 1, wherein:
Particularly, in case in the main system escalation process in the main system module 101 fatal error takes place, embedded device 100 can restart, after embedded device 100 starts, the standby system of guiding standby system module 102 starts, standby system will be finished upgrading automatically afterwards, the normal use of restorer 100.
Because a standby system backup operation system of this standby system module 102 and the upgrading part of application software, compare with application software with the complete backup operation system of prior art, the storage space that takies memory device FLASH is little, and FLASH occupies larger specific gravity in embedded device 100 design costs, lowers embedded device 100 costs thus greatly.
Fig. 2 is the implementation method process flow diagram of embedded system provided by the invention, and this embedded system comprises main system and standby system, and this embedded system is positioned at embedded device 100 as shown in Figure 1, and described implementation method comprises as follows:
Step S201, the standby system backup operation system of standby system module 102 and the upgrading part of application software, this standby system can not be wiped free of.
Fatal error takes place in the main system escalation process of main system module 101 in step S202, restarts the embedded system of embedded device 100.
Step S203, the embedded system of embedded device 100 starts the standby system of standby system module 102.
Step S204, the standby system auto-update of standby system module 102, and the embedded system of recovery embedded device 100.
In sum, the upgrading part of standby system backup operation system of the present invention and application software, and in the main system escalation process, take place to start behind the fatal error, can in the system recovery function after finishing the system upgrade failure, significantly reduce taking of storage space thus, and lower the embedded device cost greatly.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
