Studies In Integrated Oxidation Ditch DCS (Distributed Control System) CAN-Based

This thesis introduces a new method for the development of the control problems in the biology processing system of integrated oxidation ditch. It presents the DCS (Distributed Control System) practical model based CAN and adopts field controller based ADAM?000/CAN series and JPC to construct specific, practical scheme. The system includes construction of control module of the integrated oxidation ditch, usage of the CAN, design of kinds of control device and match of the terminal intellectual instruments. Also, it contains the user programs for the application of DeviceNet protocol and usage of the DLL driver in order to realize the control system. The system that adopts ADAM?000/CAN in the field has multi-aster structure, real-time capability and high reliability communication. Besides, the IPC that integrates monitor with control has rich resource. Thus, at the end the DCS (Distributed Control System) owns reliable open system architecture, quality real-time capability, high reliability, expedient operability.
