Reliability evaluation technology research for smart meters software

Smart meters software is an important basis for realizing the functions of the intelligent electric energy meter measurement, data storage, event recording, communication, display, charge control and step price. By studying the software reliability evaluation technology and the hierarchical analysis model, this paper proposed the intelligent electric energy meter reliability evaluation system based on the analytic hierarchy process. Two schemes are proposed, one is used to analyze and evaluate the performance comparison among different functions in the same meter, and the other is to compare the different meters of different manufacturers. In this system, the performance of different types of smart meter software and different modules in the same smart meter can be analyzed quantitatively by combining the two schemes.
