In the context of the deep integration of information technology and manufacturing industry and the rapid development of industrial internet,how to use big data,cloud manufacturing and other new technologies to carry out information transformation is the key to achieve capacity breakthrough and improve quality and efficiency of high-end manufacturing.However,the discrete manufacturing mode of high-end hydraulic cylinder with multiple varieties and small batches brings huge and complex drawing process data,poor information transmission and complicated production time and other problems seriously restrict enterprises development.A whole life cycle control platform was constructed for the discrete manufacturing of high-end hydraulic cylinder as the core,which contained four key information technology,namely integrated whole life cycle management (PLM),enterprise resource planning management (ERP),manufacturing execution system (MES) and data acquisition and monitoring system (SCADA).Finally,some typical cases of the core technology modules application in a factory were introduced.
