| 摘 要： | 在故障诊断中,故障通常表现为输出信号发生突变,因而对突变点的检测有非常重要的意义.鉴于传统信号处理方法的局限性,小波分析以其具备时频局部特性,成为解决此类问题的一个重要方法.推导了小波分析与奇异信号检测的之间的关系,并对某压力传感器的信号进行了奇异值的检测.

| Abstract: | In fault diagnosis research,the fault is usually accompanied with signal discontinuity.So it is of great importance to detect the signal discontinuity.The wavelet analysis is a key method to solve this kind of the problem because of its unique time-frequency localization characteristic,compared with traditional methods.The relationship between wavelet analysis and singular signal detecting is deduced,and the example of a pressure sensor singular signal detecting is presented. |
