A method for smart meter to record events

Abstract

The present invention is a method for recording events occurring in a smart meter. There are three types of events. The first type is an event with a time stamp, no delay, and no judgment record flag, and the second type is an event with a time scale, no delay, and Events with judgment record flags. The third type is events with time stamps, delays, and judgment record flags. The recording method is as follows: first, create an event parameter structure, and make a table about the occurrence of events according to the structure, and then The corresponding methods are enabled according to three different events. The above methods can systematically and completely record the events, record the events in real time, and make the event information into a table according to the structure. Through the table lookup method, only one event of the same type can be realized. Recording in one method avoids using one method for one event, which reduces code redundancy. Repeated recording of the same event can be avoided by judging the record flag, and subsequent maintenance and expansion only need to pay attention to the maintenance of the table, which is flexible and convenient.

Description

technical field [0001] The invention relates to the technical field of electric energy meters, in particular to a method for recording events by a smart electric meter. Background technique [0002] With the increase of global energy demand, in order to achieve environmental protection and reduce energy consumption, governments of different countries have begun to introduce smart grid technology and use other available energy sources to improve the demand of regions outside the grid, including China, Italy, India and the United States. All countries have developed relevant plans. In addition to the traditional functions of electricity metering and billing for power customers and power companies, smart meters are also an effective tool for communication of electricity consumption information and interaction of power supply services, and are the basis of smart grids and smart electricity consumption. [0003] Smart meters generally have an event recording function for real-ti...

AI Technical Summary

Problems solved by technology

In the smart electric meter in the prior art, if the electric energy meter has no event recording function or the event recording function is not perfect and not systematic enough, then when the meter breaks down, the on-site maintenance personnel will not be able to know the real-time status of the meter in time, and will not be able to Solve the failure of the electric energy meter in the first time, causing losses
