| Abstract: | MES system is being implemented extensively in PetroChina. As the core module of MES, real-time database system PHD （Process History Database） is the most fundamental and most important component, its implementation and deployment will determine whether the whole MES system implementation is successful or not. We mainly introduce the methods of realizing interface docking and information integration for real-time database in DCS, PLC and SCADA, and the principle, function and characteristics of real-time database PHD. Meanwhile, the effect of implementing is shown, and the practical problems met in deploying and implementing, and corresponding solution are discussed in detail. |
