Application of Optical Bus Control System in Polysilicon Project
To solve the design and construction problems caused by large scale for control system and difficulty of cable laying in polysilicon project,based on the advantages of optical bus control technology and the characteristics of polysilicon project control system,the design scheme of optical bus control system is proposed.Taking one polysilicon project as the case,the detailed design scheme for the signal transmission,power supply and grounding of the system,and the installation protection scheme of data optical treatment unit are introduced.The advantage of the control system comparing with conventional DCS is expounded.The application results indicate the control system can simplify the engineering design,and efficiently reduce the project construction cost,and increase the automation control.
