使用labview编写的灰色预测程序，判断设备故障的类型，程序已经调试通过。(LabVIEW prepared using gray prediction procedure to determine the type of equipment failure, procedures have been debug through.)

说明：  基于Labview的声音信号的采集与存储，小玩意儿(Collection and storage of sound signals)

在labview中取字符串的低八位 操作简单(Take the low eight bits of the string in LabVIEW)

通过一个例子演示如何逐张显示一个文件夹内所有的图片(An example shows how to display all the pictures in a folder by one by one.)

m文件，用于读取Labview以TDMS格式存储的数据。(m files for reading the Labview data to the TDMS format.)

自功率谱是分析非平稳信号频谱的重要手段。对于非平稳信号来说，利用自功率谱分析能够更容易找到信号中能量聚集区域，对信号中的频率分布有更好的了解。本文件中将其制作成独立子VI方便程序直接调用。(Self power spectrum is an important method to analyze the spectrum of non-stationary signals. For non-stationary signals, it is easier to find the energy accumulation region in the signal by using self power spectrum analysis, and better understand the frequency distribution in the signal. This document will be made into an independent sub VI convenience program to call directly.)

电机转速模拟，包含进度，数据记录，上下限设置，存储文件在桌面test(Motor speed simulation, including progress, data recording, set upper and lower limits, storing files on the desktop test)

利用labvIEW实现串口接收数据并实时显示波形的简单功能。(Use labvIEW Serial receive data and real-time waveform display a simple function.)

说明：  本代码编制测距传感器的串口通讯接口VI；通过波形图表显示连续读取的测距-时间曲线，并将有效测量范围外的数据滤除。(This code compiles the serial communication interface VI of ranging sensor, displays the continuous read ranging-time curve through waveform chart, and filters out the data outside the effective measurement range.)

说明：  labview写的串口调试助手，已经调试通过，使用事件驱动编写的(RS232 debuger by labview)
