normalization

说明：  使用labview进行设计，里面内含粉尘采集，气压采集，温度采集，适度采集等子程序及其集合(Design with LabVIEW, which contains dust collection, air pressure collection, temperature collection, moderate collection and other subroutines and their collection)

Labview下的Keithlley 2000电流表驱动 适用于破解版Labview2015(Driver of Keithley 2000 under LAbview)

说明：  在嵌入式开发和单片机开发，串口是必不可少是外设设备，串口可以用于调试程序的正确性，同样他可以运用于你的整个开发平台，因而知道如何利用串口调试助手是十分重要的。(In embedded development and MCU development, serial port is essential peripheral equipment, serial port can be used to debug the correctness of the program, also he can be used in your entire development platform, so know how to use the serial port debugging assistant is very important.)

使用labview的计数器功能，实现4分频编码器的测量(Using the counter function of LabVIEW to realize the measurement of 4-frequency encoder)

说明：  事件状态机(Event state machine)

本vi用于读取excel文件并将所需数据做快速傅里叶变换（FFT）处理。(This VI is used to read the excel file and to process the required data by fast Fourier transform (FFT).)

关于列车故障诊断振动信号分析研究系统的开发(Fault Diagnosis of train vibration signal analysis system development)

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.)

labview中usb raw设备的读取和写入程序 非常有用(labview usb raw device in the read and write process is very useful)

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.)
