With the development of smart grid, electric energy meters develop gradually to intelligent and multi-functional direction, which put forward higher requirements about the quality of the embedded software. For features of smart meter, combined with the method of Analytic Hierarchy Process (AHP), based on the expertise of each test item of function types using pairwise comparison method to determine the weight of each type of project, this paper realizes to evaluate the smart meter software quality based on the weight. The method has a certain reference value to evaluate the reliability and power meter software fault tolerance.
