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 maturing of fieldbus technology, DCS control system based on fieldbus technology is becoming more and more popular in chemical plant. Taking the optimization and expansion of the control system of 200,000 t / y diphenyl carbonate plant as an example, DeltaV control system, extensively using FF, Profibus DP field bus technology intelligent implementation of equipment, smart sensors, transmitters and other bus technology instrumentation to establish the process of automated system of diphenyl carbonate device, and the field bus control technology application requirements are described And explore. The control network structure based on factory control network technology is listed. The technologies of field bus, OPC, industrial Ethernet and asset management system embedded in the control system are used to build production operation, equipment condition monitoring, asset management, operation and market management The whole process of integrated factory.
