摘要
在总结农村沼气工程故障原因和专家经验的基础上 ,采用 C/ S(用户 /中间件 /服务器 )三层结构 ,按照面向对象的知识表示方法 ,以农村沼气工程故障发生原因进行分类和知识整理抽取 ,并根据数据知识是否用于推理过程 ,分别建立知识库和数据库 ,通过采用人工补充的系统学习机制和正反向混合推理策略 ,研究和构建农村沼气工程故障诊断专家系统 ,代替高级沼气工程专家对农村沼气工程运行中的故障进行科学、准确的诊断。
Based on the valid data of biogas project and expert's experience, an expert system for diagnosis and consultation of rural biogas project was build up. A C/S (user/scratchpad/server) design and object-oriented information representation method were employed in this system. The needed information was selected and arranged according to the catalogue of the faults causes. Based on the information's action, repositories and databases were established. The veracity of the result and system practicability was guaranteed by a learning mechanism of manual appending and a positive and negative commix inference model. It could achieve effective and scientific diagnosis instead of some biogas project experts in practice.
