Electric energy meter data supplementary reading method based on mirror image method

Abstract

The invention relates to an electric energy meter data supplementary reading method based on a mirror image method. According to the method, a terminal judges whether the terminal stores a last roundof supplementary reading time point in a supplementary reading process or not, a mirror image time point of the terminal for executing the reading operation is obtained according to the detection judgment condition, and then a new supplementary reading time point is determined again according to the obtained mirror image time point and the historical storage electric meter load data condition. When the supplementary reading operation is executed, the electric meter load data at the time point closest to the current time is supplemented and read firstly, so that it is guaranteed that the supplemented and read data is latest, and then the electric meter load data stored in the terminal executing the supplementary reading operation is also latest. When the terminal executes the supplementaryreading for the load data of an electric meter, each round of supplementary reading operation can supplement the data of at most one time point, so that the normal meter reading process of the terminal on the data of the electric meter can be effectively reduced. During the reading process, mirror images can be made again under the condition of zero crossing every day, and the deviation of the supplementary reading process of the terminal is prevented.

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
