中药制药过程控制系统设计研究

Design studies of process control system in the process of Chinese traditional medicine pharmacy

本文以某中药制药厂生产过程控制系统为研究对象,分析了中药生产各工段的工艺设备和控制特点。针对控制系统设备集成化程度差,自动化水平低的缺点,设计了基于PROFIBUS-DP的现场总线控制网络,介绍了控制系统的硬件配置、系统组态、软件体系。利用PROFIBUS和工业以太网的结合,实现了对中药制药各工段的集中监控、分散控制,为先进智能控制在中药制药过程中的应用构建了平台。

Based on the control system of a Chinese pharmaceutical manufacturing process, the technical equipment＇ and control characteristics were analyzed in every section of Chinese pharmaceutical manufacturing process. Aiming at the shortcomings of the equipment＇s poor integration and low levels automation, A monitoring control networks was designed based on PROFIBUS-DP, and its hardware, system configuration, software system were presented. Making use of the union of PROFIBUS and industrial Ethernet, the centralized monitor and decentralize control, which in every section of Chinese pharmaceutical manufacturing process, were realized, and the platform, which for advanced intelligent control system in the process of Chinese pharmaceutical manufacturing, was built.
