Abstract: With the complex structure of discrete manufacturing industry. The system is independent of each other and lack of data sharing. It leads to the existence of information island problem between various functional modules. Manufacturing execution system(MES) based on industrial data follow the bottom-up rules underlying (PCS) by OPC data acquisition . This method solves the problem of isomerism in the traditional method of data collection and pass through MES to the upper business system (such as ERP) and implement vertical integration of factory information. Forming abnormal information detection and fault intelligent processing module through processing of data information. The management layer can grasp the situation of the workshop in real time and discover the problems that affect the production in advance. With the input of this system it improve the plant scheduling and management efficiency. It has certain guiding significance for the practical production of the factory.
