Embodiment Construction

[0016] A method for resuming failure of remote upgrade of ARM-based wind power generation controller, comprising the following steps:

[0017] (1) The upper computer sends an upgrade command to the ARM processor. After the ARM processor receives the upgrade command, the ARM processor restarts and enters the Bootloader.

[0018] (2) The host computer sends a jump command to the Bootloader within the specified time, and jumps to the upgrade program APP1. Wherein, if the host computer does not send a jump command to the Bootloader within the specified time, it means that no upgrade is required, and the wind power generation controller automatically jumps to the normal working state.

[0019] (3) The upper computer first sends the upgrade data to APP1, and controls APP1 to receive it. After APP1 receives it successfully, the upper computer sends an instruction to APP1 to erase the FLASH address of the program to be upgraded. After APP1 receives the erase instruction, the FLASH add...

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 [0001] The invention relates to wind power generation technology, in particular to an ARM-based method for resuming remote upgrade failure of a wind power generation controller. Background technique [0002] In order to utilize wind energy reasonably and effectively, the wind turbines of the wind farm are scattered in areas with abundant wind resources in the wind farm, and the distance between the wind turbines is relatively long. How to easily upgrade the software of the control system of the wind turbine is a very important issue. If the upgrade process of the existing domestic controller’s main control program remote upgrade technology is interrupted, the remote upgrade function will not be suspended again, and only the on-site manual upgrade is required, which is not only time-consuming and labor-intensive, but also leads to increased costs. . [0003] Another Chinese patent No. is " 200810045426.3 " and " 201310155776. 6 " in the prior art respectivel...
