专家系统在循环流化床锅炉状态诊断中的应用

Expert System for State Diagnosis of Circulating Fluidized Bed Boilers

从循环流化床锅炉自身特性、系统要求出发,设计了一套循环流化床锅炉状态诊断专家系统。在分析循环流化床锅炉专家系统的基础上,详细阐述了循环流化床锅炉状态诊断专家系统中的知识表示方法、面向对象分析、置信度计算与匹配、知识库校验、软件实现、系统功能等,并经现场实践验证。

With the introduction of expert system knowledge expressing method and reasoning mechanism are studied. The knowledge expressing method of state includes method based on rule, method based on frame, on procedure and on model. The expert system for state diagnose of circulating fluidized bed boiler (CFBB) can be used to diagnose the performance state, equipment, instrument and hardware of computer in boiler system. It integrates rule maintenance, model maintenance, symptom maintenance, fault maintenance, dictation maintenance, reasoning test and explanation. Practice indicated that our method and thought are feasible and available means to keep boiler security and economy.
