Electric energy meter data management method

Abstract

The invention discloses an electric energy meter data management method. The method comprises the steps of establishing a data list, a protocol list, an object list, a DL / T698.45 protocol method listand a recording type protocol object list; and managing the data of the electric energy meter by using the established list. According to the electric energy meter data management method provided by the invention, a design architecture idea that the data, the protocol and the object are separated and a protocol data object management implementation method are adopted, so that the stability and thereliability of the electric energy meter when the DL / T698.45 protocol is used can be improved, and the coupling between the protocol of the electric energy meter and the object and the data is reduced.

Description

technical field [0001] The invention specifically relates to a data management method of an electric energy meter. Background technique [0002] With the development of economy and technology and the improvement of people's living standards, electric energy has become an indispensable secondary energy source in people's production and life, bringing endless convenience to people's production and life. The energy meter is an important metering component in the power system. It undertakes important tasks such as energy measurement, data, and data storage. Therefore, the importance of the energy meter is self-evident. The energy meter not only stores a large amount of electricity consumption data of the user, but also stores various types of data and resources during the development of the energy meter. [0003] In 2016, State Grid announced the latest object-oriented DL / T698.45 protocol. The DL / T698.45 protocol will be used in the latest electric meters, and will be used in ...

AI Technical Summary

Problems solved by technology

In this solution, because the DL / T645 protocol is relatively simple, and in order to consider all objects and functions, the protocol and the data object stored in the meter are defined in a table. The protocol and the data object are closely related and coupled, which is equivalent to completing a table at the same time. The functions of the three modules of protocol management, object management and data management have been expanded, and the function of freezing record and event record protocol data has been expanded. The form of the host computer is relatively large and complex.

In the specific implementation, whether it is the development of the host computer software or the program of the electric meter, the logic is relatively complicated, and it is not easy to develop and maintain
