Study on Management System of Energy Information in Manufacturing Processes

In order to manage energy utilization precisely in discrete manufactures and realize energy saving, energy information models were proposed firstly aiming at dispersive energy consumption and the problem of product energy consumption calculation. Secondly an energy information management system including an energy management tool, an energy consumption accounting tool and an energy consumption analysis tool was developed based on these models. Then the corresponding energy databases in discrete manufactures were designed to manage energy utilization precisely and efficiently in discrete manufactures. Thirdly some key technologies were adopted to realize multi-user information interaction and ensure security, stability, and interoperability of the information. Feasibility and effectiveness of the system were verified by a case of enterprise application.
