UPGRADING CONTROL DEVICE AND TERMINAL, TERMINAL UPGRADING METHOD AND SYSTEM, AND STORAGE MEDIUM

摘要

Disclosed are an upgrading control device and terminal, a terminal upgrading method and system, and a storage medium. During the upgrading process of a terminal, an upgrading control device acquires a current software version currently running in the terminal to be upgraded, compares the difference between the current software version and a new software version to be upgraded of the terminal to be upgraded to obtain a comparison result and controls the terminal to be upgraded to complete the upgrading according to the difference comparison result and corresponding data to be upgraded. The terminal to be upgraded in the embodiments of the present invention can be selectively upgraded according to the difference between the currently running software version and the new software version to be upgraded in the upgrading process, thus being different from an existing terminal which is required to directly upgrade the whole original software version when upgrading, hence, the number of erasing times of the terminal to be upgraded on a flash in the upgrading process can be markedly decreased, thus the time required for upgrading the terminal can be reduced, the terminal upgrading efficiency is increased, the production period of the terminal is shortened, and the production costs are decreased.
