介绍一个已用于焦化厂配煤过程实时控制和在线管理的具有两级结构的专家控制及集散控制系统。基于配煤和炼焦过程的统计数据及经验知识，建立了焦炭质量预测的数学模型和计算配煤比的规则模型。通过把数学模型和规则模型相结合，设计了计算配煤比的专家控制系统。采用S9000系列的集散控制系统，使实际的配煤比跟踪给定的配煤比。实际运行表明，配煤准确率、焦炭质量稳定率和预测精度分别达到了96％、90％和95％。
This paper presents a two-level expert control and distributed control system that has been used for real-time control and online management of coal blending process in coking plant. Based on the statistical data and experience of coal blending and coking process, a mathematical model for predicting coke quality and a rule model for calculating coal blending ratio are established. By combining the mathematical model with the rule model, an expert control system for calculating coal blending ratio was designed. Using S9000 series of distributed control system, so that the actual ratio of coal to keep track of a given coal blending ratio. The actual operation shows that the accuracy of coal blending, the stability of coke quality and the prediction accuracy reach 96%, 90% and 95% respectively.
