Real-time data stream analysis and entire process quality monitoring based on plant information

Abstract

This paper proposed a solution to do research on real-time data stream analyzing and entire process quality tracing based on PI(Plant information) in order to solve these problems that the production information was blocked and product quality was unable to be traced in the steel production.The proposed solution focused on real-time data stream partition and process monitoring,and presented statistical monitoring methods based on Statistical Quality Control(SQC) charts and process capability indices.Furthermore,a product technique and quality monitoring system was developed.The applied results indicate the implementation of real-time data stream analysis and product quality monitoring based on PI can efficiently monitor production process quality,the identification and improvement of key production technology as well.
