摘　　要：通过深入分析大屏幕投影系统的工作原理,根据专家经验和系统运行记录总结得出的故障模式,提出了将基于粗糙集理论的诊断规则自动提取方法应用于大屏幕投影系统故障诊断的专家系统,有效地化简了故障特征与诊断结果映射中的冗余信息,解决了传统专家系统在知识获取方面的"瓶颈",实现了诊断规则的自动获取。By going deep into the working way of large-screen system, and according to experts experience and failure mode which summarized by the system records,an expert system which applied rules automatic extraction methods based on the theory of rough set to large-screen system fault diagnosis, the expert system effectively simplified the fault features and the redundant information in the diagnosis results, solved the ＂bottleneck＂ of expert systems in the traditional knowledge acquisition, so the automatic obtainment of the diagnosis rules has been realized.
