高炉热状态专家系统知识库的研究

为了建立高炉热状态专家系统知识库，判断高炉热状态，阐明了知识库是高炉冶炼专家系统的核心和基础，介绍了高炉冶炼专家系统知识库的知识获取方法、知识表示方式和知识存储结构，探讨了高炉冶炼专家系统知识库的建立方法。在建立好的知识库的基础上构造了BP神经网络判断高炉热状态。离线测试结果表明，本系统建立的知识库对高炉热状态判断有很高的命中率。

Study on knowledge base of thermal state of blast furnace expert system

Aiming at building up of thermal state of blast furnace expert system knowledge base and determining the thermal state of blast furnace, a knowledge base which was the core and foundation of the smelting expert system for a blast furnace was pointed out. Then the knowledge acquisition, knowledge presentation as well as knowledge storage structure of the knowledge base were introduced. A way to build up a smelting expert system for blast furnace was discussed. The BP neural network structure was designed on knowledge base built up to determine the thermal state of blast furnace. Off-line test indicates that knowledge base built up in the system can improve the thermal state of the BF hitting rate.
