根据机械不同异常状态出现的频率和危害度的大小,引入状态权值,建立了特征参数总体敏感性和稳定性的评价指标,采用专家系统设计思想,编写了机械状态监测特征参数评价与选取应用软件,实现了特征参数的自动选取以及对特征参数和机械状态数据的有效管理。 According to the frequency and the degree of harm occurring in different abnormal states of machinery, state weights are introduced to establish the evaluation index of the overall sensitivity and stability of the characteristic parameters. Based on the design idea of ​​expert system, the evaluation and selection of the characteristic parameters of mechanical condition monitoring Software, automatic selection of characteristic parameters and effective management of characteristic parameters and mechanical state data.
