A new life prediction method of Intelligent meters based on adaptive weighting coefficients

In order to achieve the purpose of predicting the batch life index of intelligent meters in using, this paper analyzes the history failure data of the products, comprehensively considers the stresses such as temperature and humidity, then proposes an improved Weibull distribution statistical analysis method based on adaptive weighting coefficient, which is applied to the batch life prediction of intelligent meters. The prediction error of stage failure rate is less than 0.0002 fit.
