振动信号数据采集

说明：  对excel文件进行读取，并用数组形式和图的形式进行显示。统计数据中的最大值，最小值，平均值，方差。采用中值滤波，滑动平均滤波等方法去除干扰。(The excel file is read and displayed in the form of array and graph. Maximum, Minimum, Average, Variance in Statistical Data. Median filter and sliding average filter are used to remove the interference.)

说明：  通过labview对BP神经网络进行训练，得到BP模型。(The BP neural network is trained by labview to obtain the BP model.)

用于labwindows CVI开发环境 可以完成对串口收发数据十六进制和字符型格式的转换(cvi serial port)

一个基于Labview的双路示波器，功能齐全，程序清晰，易于新手掌握(A two - way oscilloscope based on Labview, full of functions, clear program, easy to master)

labview文献，基于振动信号旋转机械故障诊断的研究文献(labview literature, literature-based fault diagnosis of rotating machinery vibration signals of)

LABVIEW 数据采集，和电机控制，通过板卡可以控制电机的转速，并且能采集电机的转速信号。程序比较简单，不是采用DAQ编写。(LABVIEW data acquisition, and motor control board can be controlled via the motor speed, and can collect the motor speed signal. Procedure is relatively simple, instead of using DAQ write.)

this is a vi for labview programming

峭度指标是非平稳信号故障诊断的重要参数。峭度指标对信号中的冲击成分十分敏感，冲击成分能量越大，其峭度值就会越大，在故障诊断的时域分析中十分重要。本文件中将其独立做成了一个子vi，便于程序直接调用。(Kurtosis index is an important parameter of non-stationary signal fault diagnosis. The kurtosis index is very sensitive to the impact component in the signal. The greater the energy of the shock component, the greater the kurtosis of the signal, and it is very important in the time domain analysis of the fault diagnosis. This document will be independent of a sub VI, to facilitate direct calls to the program.)

基于LabVIEW的时域分析_自相关函数(autocorrelation function)

说明：  对于无法实现硬件定时的数据卡来说，这个vi提供了软件定时的功能(For data cards that cannot achieve hardware timing, this VI provides software timing capabilities)
