Abstract

Abstract: This article analyzes the characteristics of power payment terminal operation. Grey model theory is used to predict the change trend and specific values of the multi-dimensional status information of the equipment. Firstly, the correlation analysis method is used to extract the core data with lower correlation degree from the massive state data. Secondly, the development trend of the data is predicted by the gray prediction model. Finally, the effectiveness of the gray model is verified by actual field data.
