Software reliability and security test model of intelligent electric meters

Abstract

In recent years, smart grids have developed rapidly. As an important terminal of the smart grid, the reliability and safety of intelligent electric meters play an important role in the development of smart grids. However, in practical applications, intelligent electric meters have problems such as inconsistent software architecture, less penetration testing involved in software testing, and difficulty in finding vulnerabilities. In order to solve the above-mentioned problems, this paper analyzes the software architecture of intelligent electric meters and establishes a hierarchical system model. Then, actively analyzes the weaknesses, defects or vulnerabilities in the software to detect the design vulnerabilities and software defects in the intelligent electric meter, gives qualitative or quantitative test and verification results for its fault tolerance and ease of recovery, and establishes a complete software reliability and safety testing system, and develops a prototype system, which has good guiding significance and implementation value for the software reliability and safety testing of intelligent electric meters.
