Method for realizing multiple upgrading tasks through upgrading file package

The invention provides a method for realizing multiple upgrading tasks through an upgrading file package. The method comprises the steps of packaging upgrading files into a pkg file at a local end; and then sending the pkg file to a remote monitoring terminal for enabling the remote monitoring terminal to perform checking, decompression and updating, thereby realizing upgrading of an original system of the remote monitoring terminal. According to the method, the multiple tasks are synthesized into the upgrading file package by utilizing the local end, and then the upgrading file package is copied through an SD card or sent to the remote monitoring terminal for performing upgrading through a remote monitoring platform, so that the upgrading can be executed by one-key decompression and manual intervention is greatly reduced; and the time for manually upgrading one remote monitoring terminal is 5 minutes, and the upgrading time can be reduced to be within 1 minute by utilizing the method for realizing the multip
