摘要
通过对某工厂自动化测控系统构建要求的分析,提出了一种基于现场总线控制系统的结构,取代了通常情况下基于PLC的系统结构,并通过自主开发LonWorks现场总线通用节点,顺利完成了工程实施。实施过程及运行情况表明,基于LonWorks现场总线的工厂测控系统实时性好,可靠性高,并大幅降低了系统构建成本,提高了测控系统性价比。
Through the analysis of one factory＇s automation measurement and control system, a system architecture based on FCS is brought up, instead of common system architecture based on PLC. And through developing LonWorks field bus common interfacing node by self, the system is smoothly built. The process of construction and running case reveal that the factory measurement and control system based on Lonworks FCS has good real-time character, high reliability, and low system construction cost. measurement and control system cost perform- ance is improved.
