A method of supplementary copying of electric energy meter data based on mirror method

Abstract

The invention relates to a method for supplementary copying of electric energy meter data based on the mirror image method. The terminal makes a judgment on whether it has stored the time point of the last round of supplementary copying in the supplementary copying process, and obtains the terminal to perform the copying operation according to the detection and judgment situation The mirroring time point, and then according to the obtained mirroring time point and the historical stored electricity meter load data, determine the new supplementary reading time point again. When performing the supplementary copy operation, first supplement the meter load data at the nearest time point to the current time to ensure that the supplementary copied data is the latest, and then the ammeter load data stored in the terminal performing the supplementary copy operation is also the latest; the terminal executes For the supplementary reading of the electric meter load data, each round of supplementary reading operation can supplement the data of one time point at most, which can effectively reduce the normal meter reading process of the terminal to the electric meter data; All will be re-mirrored to prevent the terminal's supplementary copying process from going off track.

Description

technical field [0001] The invention relates to the field of electric energy meters, in particular to a method for supplementary copying of electric energy meter data based on a mirror image method. Background technique [0002] In the field of electric power, terminals and a certain number of electric energy meters form a data acquisition network. In this data acquisition network, the terminal is responsible for completing the collection of energy meter data in the station area. For example, the terminal generally collects the data of the energy meter managed in the jurisdiction through 485 communication, and then stores the response data information of the energy meter in the terminal middle. [0003] According to the technical requirements of the electric power field, the terminal needs to have the function of collecting the load curve of the electric meter, that is, the terminal can read the electric energy meter data of the electric energy meter at a fixed time, and us...

AI Technical Summary

Problems solved by technology

[0009] First of all, since the terminal is set to make up the meter reading data at a fixed time point, and there are usually a lot of meter data to be read, it is easy to affect the normal meter reading process of the terminal due to the supplementary reading process;

[0010] Secondly, the supplementary copy process performed by the terminal is not instant, but the supplementary copy will be started the next day after the terminal finds that there is missing data, which will also cause the supplementary meter data to be not timely
