CIMS applied in water treatment

How to implement integration and optimal control is most important in CIMS (Computer Integrated Manufacturing System). In order to realize the integration, we must integrate the data, which are collected by many sensors, and the information, which exist in the heterogeneous systems with different software and hardware frameworks. The aim of the integration is to share the resources, and more importantly to optimize the control on the basis of the integration and achieve more benefit. In the light of the theory and technology of CIMS, combining the CIMS project which is conducted by the Changsha Water Supply Corporation, the author studies in great detail the integration and optimal control in the process of water treatment. Taking advantage of the technology of CORBA (Common Object Request Broker Architecture) and the multi-sensor information fusion, the author brings forward the common arithmetic in the integration and the new optimal control methods in the control of the alum dosages, and brings them to success in water treatment.
