本文研究的是利用奇异性指数实现对设备状态监视和故障预警功能。首先用LabVIEW 采集传感器电信号,然后对采集到的电信
号进行小波变换得到信号包络奇异点的奇异性指数,即设备运行状态的特征值(In this research project, we use LabVIEW to do wavelet-transformation to the signal collected by sensors in order to get singularity
index from the singular points of the particular signal’s envelope. Through comparing this eigenvalue to the figures in a standard database, we can
know the functional status of the instruments. Not only the diagnoses are continuously displayed, but alarms about signs of dysfunction will also be
raised in a proper way. In other words, both the supervision of the instrument and warning of dysfunction can be achieved)

ConstructWaveBaseFunction
说明: 紧支撑小波基的构造。
以Daubechies小波滤波器系数为例,推导出小波函数及尺度函数,并画出其图像.
void Convolution(double* pShortData, int nShort, double* pLongData, int nLong)
int CalcScaleFunction(double* pOutData)
int CalcWaveletFunction(double* pOutData)
Convolution()不是通用的离散卷积代码,而是简单地实现了后面两个函数需要的离散卷积,它要求输入的前一个数组长度小于后一数组长度,而且卷积结果就直接覆盖存储在后一数组中。CalcScaleFunction()计算尺度函数,CalcWaveletFunction()计算小波函数。
(Compactly supported wavelet bases constructed. To Daubechies wavelet filter coefficients as an example, the derived wavelet function and scaling function, and draw their images. Void Convolution (double* pShortData, int nShort, double* pLongData, int nLong) int CalcScaleFunction (double* pOutData) int CalcWaveletFunction ( double* pOutData) Convolution () instead of generic discrete convolution code, but simply the realization of a function behind the need for two discrete convolution, which requires input before an array length is less than the array length of the latter, but the result of convolution directly covered by the latter is stored in the array. CalcScaleFunction () calculated scaling function, CalcWaveletFunction () calculation of wavelet function.)
