August 26 news: According to information from the National Intellectual Property Administration, Shandong Shanda Electric Power Technology Co., Ltd. has applied for a patent titled “A Remote Upgrade Method and System for Power Equipment Based on ARM and FPGA.” The application publication number is CN122633217A, the application number is CN202611122770.2, the application publication date is August 25, 2026, and the application date is July 28, 2026. The inventors are Meng Lingjun, Sun Chaoyue, Shi Lei, Song Chunliang, Ren Liuyan, Zhang Sichao, Wu Xiuqun, and Wu Baosheng. The patent agency is Jinan Shenda Intellectual Property Agency Co., Ltd., and the patent agent is Zhang Qingqian. Classification numbers are G06F8/654, G06F16/16, and G06F16/172.

Patent abstracts indicate that this invention relates to the field of power equipment technology. To solve the problem that existing solutions only support fixed frame-length transmission and have poor adaptability, it provides a remote upgrade method and system for power equipment based on ARM and FPGA. The remote upgrade method for power equipment based on ARM and FPGA includes: the power monitoring terminal receiving and parsing remote upgrade instruction frames; after the power monitoring terminal receives each partitioned upgrade file, performing a CRC check for each partitioned upgrade file based on partition parameters and recording the overall package data CRC check sum I; if the verification is correct, integrating and storing the corresponding upgrade files in an external Flash storage module; the power monitoring terminal determining the upgrade targets as ARM/FPGA, responding to the corresponding upgrade start instruction, and initiating the ARM/FPGA upgrade process accordingly. This enables independent, precise, automated upgrading of ARM/FPGA, ensuring upgrade stability and compatibility with the master station.
