In specific implementation, the first electronic product starts to be upgraded, and acquiring the power failure state in the upgrading process may include: and when the first electronic product starts to be upgraded, synchronously starting the thread to track the power-down state of the first electronic product. In the first electronic product upgrading process, the system can detect the progress in the upgrading process. If the power supply environment is normal, normal upgrading can be carried out, and the upgrading progress is from 0 to 100%. If the system suddenly encounters an adverse condition and the power is cut off in the upgrading process, the upgrading progress and the power-off state in the upgrading process are detected. If the power is lost in the upgrading process, the power-down state in the upgrading process can be set to true, otherwise, false can be set. The power-down state during the upgrade process may be saved in the uboot.
S3, judging the power failure state of the first electronic product in the upgrading process, if true, reading the software upgrading identification of the first electronic product when the first electronic product is electrified next time, starting uboot upgrading, downloading the software upgrading package from the second electronic product to the first electronic product, otherwise, normally starting the first electronic product.
