Embodiment

[0014] In this embodiment, the specific process steps for realizing the parameter setting of the smart electric energy meter are as follows:

[0015] (1) Generate executable code from the source code through the software compilation process, and file for the executable code to be generated through the State Grid;

[0016] (2) Convert the structured parameter files arranged in the order of storage addresses into binary parameter files through a binary conversion tool;

[0017] (3) After the binary parameter file is converted into a parameter file in the same format as the executable code generated during the compilation process, the parameter file in the same format as the executable code and the executable code file are combined into an executable program;

[0018] (4) Download the synthesized executable program to the data storage space corresponding to the MCU main chip of the electric energy meter, and the download time is 10‐90 seconds;

[0019] (5) The energy meter is st...

Abstract

The invention belongs to the technical field of watt-hour meter parameter setting, and relates to an intelligent watt-hour meter parameter setting method. Executable codes are first generated from source codes by a software compilation process, and the executable codes to be generated are filed via the state grid; after structured parameter documents which are arranged according to the sequence of memory addresses are then converted into binary parameter documents by a binary conversion tool, the binary parameter documents are converted into parameter files which have the same format as that of the executable codes generated by the compilation process, and the parameter files with the same format as that of the executable codes and the executable code file are then integrated into an executable program; the integrated executable program is then downloaded into a data storage space corresponding to an MCU (microprogrammed control unit) master chip of a watt-hour meter, the watt-hour meter is started, and the program loads parameters from the corresponding data storage space. According to the intelligent watt-hour meter parameter setting method, the principle is reliable, the technical process is simple, operation is convenient, the parameter setting time is short, and the production efficiency is high.

Description

Technical field: [0001] The invention belongs to the technical field of electric energy meter parameter setting, and relates to a process method for setting electric energy meter parameters, in particular to a method for setting intelligent electric energy meter parameters. Background technique: [0002] At present, there are two ways to set the parameters of the electric energy meter: one is to integrate the specific parameters and the parameter setting process into the executable program file, burn the executable program file into the main chip of the electric energy meter MCU, start the electric energy meter, and set the parameters The process loads specific parameters, and every time there is a new parameter change, a new program version needs to be issued; second, during the start-up process of the electric energy meter, the program opens up a corresponding size storage space, and the production personnel operate the automatic parameter setting software of the electric e...
