摘要
该文以空气开关在操作过程中的声音信号为对象,根据G-P算法阐述了空气开关声音信号关联维数的计算方法,并定量地分析了不同的噪声强度对计算关联维数的影响。通过计算表明,关联维数能够有效分辨空气开关机械机构的正常与异常状态,可以充当空气开关状态检测的特征参量。
Voice signals in operation of air switch are the objects of this paper.According to the G-P computational method,the calculation of correlation dimension of air switch voice signals was conducted,and quantitative analyze the influence of noise on the calculation of correlation dimension.The results show that the correlation dimension can tell the differences between the normal and abnormal operating conditions of a air switch,and it can be used as a characteristic parameter in detection of condition of air switch to some extent.
