1 集散控制系统基本特征集散控制系统是现代化工业实现自动化不可缺少的工具。从整体逻辑结构上讲是一个分支树结构,按系统结构进行垂直分解,它分为过程控制级、控制管理级、生产调度级和经营管理级,贯彻既集中管理又分散控制的设计原则。DCS系统具有通用性强、系统组态灵活、控制功能完善、数据处理方便、显示操作集中、人机界面友好、安装简单规范化、调试方便、运行安全可靠的特点。它能够适应工业生产过程的各种需要,提高生产自动化水平和管理水平,提高产品质量,降低能源消耗和原材料消耗,提高劳动生产
A distributed control system basic features Distributed control system is an indispensable tool for modern industrial automation. From the overall logical structure is a branch tree structure, according to the vertical decomposition of the system structure, which is divided into process control level, control management level, production scheduling level and management level, implementing both centralized management and decentralized control design principles. DCS system has the characteristics of strong versatility, flexible system configuration, perfect control function, convenient data processing, centralized display, friendly man-machine interface, easy and standardized installation, convenient debugging and safe and reliable operation. It can adapt to the needs of industrial production process, improve the level of production automation and management, improve product quality, reduce energy consumption and raw material consumption, improve labor productivity
