Abstract
The invention discloses a wind power generation controller failed remote upgrade recovery method based on ARM. The wind power generation controller failed remote upgrade recovery method comprises (1) sending an upgrade instruction to an ARM processor, entering a Bootloader after the upgrade instruction is received; (2) sending a jump instruction to the Bootloader and jumping to an upgrade application APP1; (3) controlling the APP1 to receive upgrade data, erasing the FLASH address of the application to be upgraded first, then starting to upgrade the FLASH write-in of data, and finally obtaining the upgraded application APP2; (4) sending an upgrade complete instruction to the APP1, entering the Bootloader, and verifying the size of the APP2, if the verification result is correct, jumping to the APP2 and completing the upgrade; if the verification result is incorrect, waiting for a host computer to send a new upgrade instruction. According to the invention, the problem that after the upgrade process is interrupted, the system cannot hang up the upgrade task again is solved.
Description
Technical field
The present invention relates to wind turbine power generation technology, more particularly, to a kind of wind power generation controller remote upgrade mistake based on ARM
Lose recoverable method.
Background technology
In order to rationally and effectively utilize wind energy, the blower fan of wind energy turbine set is scattered in the abundant area of each wind resource in wind energy turbine set
Domain, the distance between each wind power generating set farther out, even if in the case that weather is fine, completes patrolling and examining also extremely of whole wind field
Need less to drive more than a few hours, how easily the control system of wind power generating set to be carried out software upgrading be one very heavy
The problem wanted.The primary control program remote upgrade technology of existing domestic controller is occurring in the case that escalation process is interrupted, far
Journey upgrade function will be unable to hang up again, only goes to carry out manually upgrading on the spot to scene, not only wastes time and energy, also result in cost
Increase.
The prior art that China Patent No. is " 200810045426.3 " and " 201310155776. 6 " is separately had to disclose respectively
The remote upgrade method of wind power generating set, but above-mentioned prior art cannot be hung up after all there is remote upgrade failure and again rise
The problem of level.For this reason, in the urgent need to recoverable technology after a kind of failure of wind power generation controller remote upgrade.
Content of the invention
It is an object of the invention to overcoming the above-mentioned problems in the prior art, providing and a kind of being sent out based on the wind-force of ARM
The electric controller remote upgrade recoverable method of failure, the present invention solves that after being interrupted in program escalation process, system cannot
Hang up the problem of upgrading task again, so that remote upgrade operation is more stable.
For achieving the above object, the technical solution used in the present invention is as follows：
A kind of based on ARM wind power generation controller remote upgrade failure recoverable method it is characterised in that：Walk including following
Suddenly：
（1）Host computer sends upgrade command to arm processor, and arm processor enters Bootloader after receiving upgrade command；
（2）Host computer sends jump instruction to Bootloader, jumps to ROMPaq APP1；
（3）Control APP1 to receive upgrading data, after receiving success, first wipe the FLASH address of program to be upgraded, then start to upgrade
The FLASH write of data, finally obtains program APP2 after upgrading；
（4）Host computer is sent completely upgrade command to APP1, and arm processor enters Bootloader, right in Bootloader
The size of APP2 is verified, if check results are correct, jumps to APP2, upgrading completes；If check results are incorrect,
Wait host computer to send new upgrade command in Bootloader, and repeat the above steps are until upgrading completes.
Described step（3）In, after the completion of upgrading data write, whether first detection upgrading data is complete, if completely, then enters
Enter step（4）.
Described step（3）In, the size of write upgrading data after the completion of upgrading data write.
Using it is an advantage of the current invention that：
In the present invention, ROMPaq APP1 is written to FLASH, then no matter because power down or other reason are all without to ROMPaq
APP1 impacts.In addition, APP1 starts the erasing of program FLASH address to be upgraded again in the present invention after having received upgrading data
With the FLASH write of upgrading data, and write the size of upgrading data after the completion of upgrading data write again so that controller
Even if because the write operation that power down or other reason lead to does not complete the safety that yet will not jeopardize blower fan in escalation process.This
The size of APP2 being because detecting write in Bootloader and the size whether being stored in data of upgrading in FLASH
Cause, if unanimously just APP2 can be entered, if inconsistent, continue the upgrade command waiting host computer to send in Bootloader.Institute
So that the present invention solves controller power down, serial ports disconnecting, host computer closing during system remote upgrade and rise
After situations such as level computer is restarted cannot remote upgrade again problem.To the complexity reducing the upgrading of wind field master control system, plus
The reliability of strong remote update system, fan operation safety, the maintenance cost reducing wind field all makes great sense, so that
Obtain remote upgrade operation more stable.
Brief description
Fig. 1 is the logic chart of the present invention.
Specific embodiment
A kind of wind power generation controller remote upgrade recoverable method of failure based on ARM, comprises the steps：
（1）Host computer to arm processor send upgrade command, after arm processor receives upgrade command, arm processor restart into
Enter Bootloader.
（2）Host computer sends jump instruction to Bootloader at the appointed time, jumps to ROMPaq APP1.Its
In, if host computer does not send jump instruction to Bootloader at the appointed time then it represents that not needing to upgrade, automatically jump to
The normal operating conditions of wind power generation controller.
（3）Host computer first sends upgrading data to APP1, controls APP1 to receive, after APP1 receives success, host computer to
APP1 sends the instruction of the FLASH address wiping program to be upgraded, and APP1 treats the FLASH of ROMPaq after receiving erasing instruction
Address is wiped, and behind erasing FLASH address, host computer sends write instruction to APP1 again, and the FLASH starting upgrading data writes
Enter, program APP2 after APP1 completes the FLASH write of upgrading data, after being upgraded.Wherein, complete in upgrading data write
The size of upgrading data must be write afterwards.
In this step, after the completion of upgrading data write, to host computer, host computer sends inspection to APP1 feedback write result again
Survey instruction, whether complete for detection upgrading data, if upgrading data write is detected is complete, enter step（4）If, inspection
The upgrading data measuring write is imperfect, then host computer resends upgrading data.
（4）Host computer is sent completely upgrade command to APP1, and arm processor reboots into Bootloader,
In Bootloader, the size of program APP2 after upgrading is verified, to guarantee the data integrity of APP2, if verification knot
Fruit is correct, and that is, the size of APP2 and the in the same size of data of upgrading, then jump to APP2, represents that upgrading completes, wind-power electricity generation control
Device normal work processed；If check results are incorrect, that is, the cause not of uniform size of the size of APP2 and upgrading data, then exist
Wait host computer to send new upgrade command in Bootloader, and repeat the above steps are until upgrading completes.
The present invention adopts above-mentioned steps, solves and controller power down, serial ports connection during system remote upgrade
Interrupt, host computer close and upgrading computer situations such as restart after cannot remote upgrade again problem.To minimizing wind field master control
The complexity of system upgrade, strengthens the reliability of remote update system, fan operation safety, reduces the maintenance cost of wind field all
Make great sense, so that remote upgrade operation is more stable.
