moving-average

歪度指标是描述信号概率密度函数的重要参数。在对非平稳信号进行时域分析时，利用歪度指标反映了振动信号的非对称性，用来判断轴承是否发生碰磨。本文件中将歪度指标独立制作了子VI，便于labview程序调用。(The skewness index is an important parameter to describe the probability density function of a signal. When the non-stationary signals are analyzed in time domain, the skewness index is used to reflect the asymmetry of the vibration signals, which is used to judge whether the bearings have been touched or not. This document will be independent of the index made a sub VI, easy for LabVIEW program calls.)

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.)

编辑波形，可以生成各种波形,比如方波，正弦，锯齿波等(wave editor)

说明：  电机控制器的串口通信界面,基于labview visa,德马克电机(Serial communication interface of motor controller based on LabVIEW visa, demarcation motor)

利用Labview软件编写读取二进制文件程序(The Labview program reads the binary file)

CRC16的9个LabVIEW算法CCITT,CCITT-KERMIT,CCITT-X25，CCITT-XMODEM,DNP,IBM,MAXIM,MODBUS,USB，开发环境LabVIEW2013(9 LabVIEW algorithm of CRC16: CCITT,CCITT-KERMIT,CCITT-X25，CCITT-XMODEM,DNP,IBM,MAXIM,MODBUS,USB The development environment version is LabVIEW 2013)

编写软件为labview2011，功能为读取txt文件中的值，并绘制电平图，设置了双游标，可以自动准确计算出两游标X轴时间差值。txt的内容为上升沿或下降沿的时间信息，首位0代表下降沿，1代表上升沿。后面位的值乘16代表沿的绝对时间(program software is the labview2011, functions is to read txt file values​ ​ , and draw level diagram, set up a dual cursors, you can automatically and accurately calculate the time difference between the two cursors X axis. txt contents of rising or falling time information, the first 0 represents falling, a representative of the rising edge. Followed by 16-bit value represents absolute time along)

基于LabVIEW软件编写，利用Hilbert变换实现回声信号的检测。(Hilbert transform echo signal detection)

说明：  在LabVIEW中Modbus应用编程实例(Modbus library usage)

labview实现对变压器局方数据的采集及后期处理，如根据局放数据实现局放定位等。(The labview achieve transformer Bureau data acquisition and post-processing, such as PD the data realization PD positioning.)
