Electric energy meter software upgrading file reliability test method

Abstract

The invention discloses an electric energy meter software upgrading file reliability test method. The method comprises the steps of judging whether an import check value of an upgrading import file isconsistent with a preset check value of an upgrading source file or not; judging whether the storage unit upgrading file is consistent with the upgrading source file or not; judging whether the identifier of the upgraded electric energy meter software is consistent with the identifier before upgrading or not; and judging that the electric energy meter software is upgraded successfully. Comparingwith the related art, according to the method, the check value of the upgrade import file is compared with the check value of the source file; the storage unit upgrading file is directly compared withthe upgrading source file; the upgraded identifier is directly compared with the identifier before upgrading, so that the situation that the upgrading file of the storage unit stored in the electricenergy meter memory is inconsistent with the upgrading source file due to a communication channel, and consequently the software upgrading of the electric energy meter fails can be avoided, the accuracy of the upgrading file is ensured, and the success rate of the software upgrading of the electric energy meter is increased.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a method for testing the reliability of electric energy meter software upgrade files. Background technique [0002] In recent years, as China Southern Grid / State Grid has vigorously promoted the transformation of smart grids, hundreds of millions of smart meters have been installed on the grid. According to statistics, 20% of the faults produced by the electric energy meter are software faults. When the electric energy meter fails, the meter can only be replaced, resulting in a waste of resources. The new-generation smart energy meter proposes an online software upgrade function, and the reliability of the software upgrade file directly affects the online operation quality of the energy meter. [0003] At present, the reliability test of the software upgrade file of the electric energy meter mainly judges whether the software upgrade is successful by reading the hash value a...
