基于数据库的燃煤锅炉事故诊断专家系统的设计与实现

DESIGN AND IMPLEMENTATION OF THE FAULT DIAGNOSIS EXPERT SYSTEM FOR THE FUEL COAL BOILER BASED ON THE DATABASE

采用MSSQLServer 7.0设计知识库 ,VisualBasic 6.0编程实现了燃煤锅炉事故诊断专家系统。本系统知识表示采用了基于概率逻辑的产生式规则形式 ,并用数据库的方法存储管理知识库。推理机采用规则值的方法 ,并应用主观Bayes理论建立了不确定性推理模型。实现了一种较为理想的不精确推理。

In the paper,the knowledge base is designed by MS SQL Server 7.0 and the fault diagnosis expert system for the fuel coal boiler is implemented by Visual Basic 6.0.The method of knowledge representation is genetic algorithm based on probability logic,and the database method to store and manage the knowledge base is used.The method of rule value is used in inference,and the uncertain inference model based on subjective Bayes method is build up.The reasoning under uncertainty is implemented in the expert system.
