摘要
随着现场总线技术的日益成熟,基于现场总线技术的DCS控制系统在化工装置应用越来越普遍,以20万吨/年产量的碳酸二苯酯装置控制系统的优化扩建为例,阐述基于艾默生DeltaV控制系统,广泛采用FF、Profibus DP现场总线技术智能执行设备、智能传感器、变送器等总线技术仪表组建碳酸二苯酯装置自动化系统的过程,并对现场总线控制技术应用的要求进行了说明和探讨。列举了基于工厂管控网技术的控制网结构,利用现场总线技术、OPC、工业以太网以及内嵌于控制系统的资产管理系统等技术,构建生产操作、设备状态监控、资产管理、经营及市场管理一体化工厂的全过程。
With the development of fieldbus technology,more and more chemical factories use the DCS based on fieldbus technology as the control system. This thesis takes the 200kt/y diphenyl carbonate plant which implements process optimization and extension as the example to present the process how the Emerson DeltaV system,the smart actuator,smart sensor,transmitter and other smart instrument devices based on FF,Profibus DP,and Hart fieldbus technology set up the automatic control system of the plant. The requirement of fieldbus application is specialized. Based on the control network structure,fieldbus technology,OPC,industry Ethernet and the embedded asset management system, etc. are used to realize the combined process control of device status supervision,asset management,production and market management.
