摘要
在综述DCS和现场总线技术的基础上,提出了多台智能仪表控制系统的概念,利用控制PC机通过串行通信接口卡、RS-485总线与智能仪表相连,构建多智能仪表DCS系统,分析了系统的结构,提出了系统的通信协议,其控制对象既可以是实际的工业过程对象,也可以是被控对象模型系统。监控软件提供了明确的控制接口,可以方便地实现各种控制算法的控制实验。
A multi-intellectual-instrument DCS(distributed control system) with PC, serial communication card, RS-485 bus and intellectual instruments is construct, which is based on summarizing DCS and locale bus technology. The system structure is analyzed in the paper and its communication protocol is put forward. It can control not only some real objects but also the model-object system. The monitor software has been offered a clear interface for control experiments.
