The invention discloses a method for realizing local maintenance of a centralized meter reading terminal by using a U disk. The method comprises the steps as follows: a programmer writes an instruction with a function expected to be realized in a script, then stores the script into a script file, and then copies the script file into the U disk; the U disk is inserted into a USB plug seat of the centralized meter reading terminal, and then by means of a button on the centralized meter reading terminal, the centralized meter reading terminal loads the script file in the U disk into a storage of the centralized meter reading terminal; and an MCU ( microprogrammed control unit) in the centralized meter reading terminal reads and executes the instruction of the script file in the storage by means of the button on the centralized meter reading terminal according to a prompt on a display of the centralized meter reading terminal, and/or transmits data in the centralized meter reading terminal ...
