摘要: 本文研究了生产系统监控中的故障发现问题,建立了具有学习功能的故障发现系统。该系统基于模式识别理论与模糊理论解决了模式不可分情况下的故障发现决策问题。另外提出了故障发现有效性的评价方法。该方法可用于评价不同随机过程及不同故障严重程度故障发现的有效性。文末通过仿真实验,验证了故障发现系统的有效性,并给出了有关监控者工作特性的研究结果。

Abstract: This paper deals with the failure detection of manufacturing systems. A learnable failure detection system has been proposed. Based on the pattern recognition theory and fuzzy theory the decision problem of failure detection has been solved for the case that two pattern can not be separated clearly. And an evaluation method for failure detection effectiveness has been proposed, which can be used for evaluation effectiveness of failure detection of different random processed and different failure grade. Finally, the effectiveness of failure detection system is validate by computer simulation. The results of human performance in monitoring are given in this paper as well.
