Digital signal processor (DSP)-controlled single-board equipment and its remote update method and server

Abstract

The invention relates to digital signal processor (DSP)-controlled single-board equipment and its remote update method and server. The digital signal processor-controlled single-board equipment and its remote update method and server are utilized in a wind-powder conversion system. The remote update method comprises that: S1, a remote update command and machine code data for software version update are transmitted by a remote update server; and S2, an DSP-controlled single board receives the remote update command by a communication device, then receives the machine code data for software version update, and utilizes the machine code data for software version update to write on-chip FLASh so that configuration is finished. In the invention, the machine code data for software version update is directly transmitted to the DSP-controlled single board located at a remote port and is directly utilized for programming of on-chip FLASH of the DSP-controlled single board, wherein compared with programming adopting DSP project files, the direct programming of on-chip FLASH does not need special programming equipment and realizes that machine codes occupy a small on-chip FLASH space.

Description

technical field [0001] The present invention relates to the field of embedded devices, more specifically, to a DSP control single-board device and its remote upgrade method and server, especially the DSP control single-board device and its remote upgrade method and server applied to wind energy converters . Background technique [0002] DSP (digital signal processor, digital signal processor) is a unique microprocessor, a device that processes a large amount of information with digital signals. Not only is it programmable, but its real-time running speed can reach tens of millions of complex instruction programs per second, far exceeding that of general-purpose microprocessors. It is an increasingly important computer chip in the digital electronic world. [0003] At present, the DSP control single board has been widely used in various embedded devices, such as the control board of the wind energy converter. The DSP program of the DSP control single board is usually solidi...
