Method for upgrading firmware based on terminal state

The invention relates to a method for upgrading firmware based on a terminal state. The method comprises the following steps: S10, actively or passively triggering a terminal to check whether matched upgrading package information exists to a cloud; S20, if so, acquiring resources information of the terminal, and judging whether the resources information of the terminal meets resources requirements required by the upgrade package or not; S30, if so, downloading the upgrade package, and if not, regenerating a new upgrade package according to the resources information of the terminal and downloading the new upgrade package; S40, judging whether the source version matches the new upgrade patch or not according to verification information in the downloaded upgrade patch; and S50, if so, executing upgrading and reporting an upgrading result to the cloud, otherwise, directly reporting the upgrading result to the cloud. The idle prediction of the terminal resources during upgrading can be given to the maximum extent
