Specifically, user will assign firmware upgrade order by input equipment when needing to upgrade firmware, it is main
After thread receives firmware upgrade order, can check whether the firmware version of current mounted firmware is in current planning
Due firmware version is to newly establish because portion firmware may individually carry out equipment corresponding to update or the firmware
Standby, firmware version has been newest, so distinguishing consolidating of needing to update in main partition by detecting to save renewal time
Part avoids carrying out repeating update to the firmware for being latest edition.
It is understood that main partition includes multiple a variety of different firmwares, each firmware has respective firmware version, needs
Otherwise same update packet is upgraded.
S13: being that the inconsistent firmware of firmware version distributes corresponding sub thread using main thread.
Specifically, play multithreading effect to save update time, no longer firmware is sequentially updated by main thread,
But be changed to main thread and distribute the more new task of each firmware at most a sub thread, each sub thread is responsible for the liter of a firmware
Grade, it is mutually indepedent between each sub thread, it is independent of each other, forms the asynchronous upgrade of multiple threads, accelerate updating speed.
S14: firmware upgrade is carried out to firmware corresponding in main partition using each sub thread is independent respectively.
Specifically, each sub thread respectively obtains firmware update packet corresponding with the firmware of distribution, individually to institute
The firmware of distribution is upgraded, can be mutually internally inconsistent with the upgrading progress of then asynchronous upgrade, each sub thread, certainly, can also
To there is the identical situation of progress, further, even if failing in some sub thread escalation process, it will not be influenced
The upgrading progress of its sub thread.
S15: if sub thread sends firmware upgrade using sub thread and complete information to main thread to firmware upgrade success；
S16: after completing information using the firmware upgrade that main thread receives whole sub thread feedbacks, to what is all upgraded successfully
Firmware initiates to reset operation, completes upgrading.
It is understood that after sub thread upgrades, in order to feed back to main thread upgrading ending message, so as to main thread
Subsequent operation is carried out, after sub thread upgrades, firmware upgrade is sent and completes information to main thread, main thread receives sub thread hair
After information is completed in the firmware upgrade sent, it will the whether whole sub threads of statistics complete upgrading, if whole sub threads complete upgrading,
Main thread can execute reset operation, and newest firmware version after updating system operation completes entire escalation process.
Specifically, executing reset operation by main thread again after all upgradings is because user is when designing upgrading task, meeting
In view of the compatibling problem between each firmware, if in the case where portion firmware upgrades successfully portion firmware upgrading failure, it is still right
The firmware upgraded successfully carries out reset operation, and the firmware that may cause upgrading and the firmware not upgraded successfully generate compatibling problem,
Lead to not carry out communication cooperating, makes system failure, so, only after whole firmware upgrades, main thread just meeting
Same execution resets operation.
It should be noted that the case where being not in upgrading failure when system is normal due to firmware upgrade, when certain
There is upgrading failure in one sub thread, then is likely to show that the firmware breaks down, for example, stuck or corresponding hardware communication occurs
Mistake etc. needs to safeguard, therefore, once there is mistake, then terminates upgrading.
As it can be seen that the embodiment of the present invention gives up the method for single thread upgrading, the upgrading task for the firmware for needing to upgrade is distributed
At most a sub thread, each sub thread upgrade a firmware, asynchronous upgrade between sub thread, realize multi-threaded parallel liter
Grade, improves updating speed, portion firmware is not avoided to upgrade, compatibility issue caused by portion firmware upgrading failure, only complete
Main thread can just execute reset operation after the completion of portion's firmware upgrade, it is ensured that the stability of system.

S26: after completing information using the firmware upgrade that main thread receives whole sub thread feedbacks, to what is all upgraded successfully
Firmware initiates to reset operation, completes upgrading；
S27: if sub thread fails to firmware upgrade, carrying out firmware upgrade to corresponding firmware again using sub thread,
Until upgrading number reaches preset threshold value again, then upgrading failure information is sent to main thread；
S28: using main thread according to upgrading failure information, upgrading is terminated.
Specifically, can initiate upgrading again again if sub thread fails for the first time in firmware upgrade process and appoint
The problem of self-elimination upgrading fails is attempted in business, if still failed after repeatedly reattempting to, is upgraded again until reaching preset
Threshold value can then abandon continuing to upgrade, show not solving the problems, such as by way of voluntarily upgrading again for example, 5 times, this
