Analysis on the Maintainability of Smart Meter Software for Full Lifetime

Abstract

Abstract With the deepening of Internet concept and electricity marketization reform, more requirements are put forward for metering equipment, and the scale and complexity of software also increase. The new generation of intelligent electricity meters meet the IR46 standard and adopt the multi-core modular design scheme, which also puts forward higher requirements for the maintainability of software. This paper starts from the key control points of the whole life cycle of intelligent electricity meters and combines the characteristics of software testing, so as to analyze and evaluate the maintainability of the software. Firstly, the factors that influence the maintainability of watt-hour meter products are analyzed, and the software key data is considered from the perspective of software development and design. Then, the index system of the maintainability of the intelligent software is established, and the key points of the maintainability test and the weight of each index are analyzed in combination with the testing technology of the intelligent meter software and the analytic hierarchy process.
