轴承信号分析
共振解调的过程如下:首先对采集到的信号进行傅里叶变换,然后利用传感器自身的谐振频率进行分析,对滤波后的信号进行包络,包络以后去除了高频部分,得到包络信号,再对改进的包络信号进一步进行低通滤波,最后对最终得到的信号进行傅立叶变换求其频谱图。共振解调的原理及其过程可以用图2 来进行表述。(The process of resonance demodulation is as follows: First, Fourier transform is performed on the collected signal, and then the resonance frequency of the sensor is used for analysis. The filtered signal is enveloped, and the high frequency part is removed after enveloping to obtain an envelope. The signal is further subjected to low-pass filtering on the improved envelope signal. Finally, the spectrum of the resulting signal is Fourier-transformed. The principle of resonant demodulation and its process can be expressed in Figure 2.)

createButtonLabel
buttonIcon = createButtonLabel(string,PVs,figOpt)
Have you ever been frustrated by an inability to label a vertically oriented pushbutton or uicontrol with a string? This function is for you!
All valid Parameter-Value pairs, INCLUDING TEXT ROTATION, are supported. Note that this function requires the Image Processing Toolbox, and that it triggers the creation of a temporary figure, which will be momentarily visible during button-label creation.
