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.)

基于labview平台，以弹簧-质量-阻尼系统为基础，做出二阶虚拟仪器实验平台。包括二阶系统的时域，频域响应动态分析。实现单位阶跃信号输入弹簧-质量-阻尼系统后的动画演示。 (Labview based platform to spring- mass- damper system based on virtual instrument to make second order experimental platform. Time domain including second-frequency-domain dynamic response analysis. Per unit step signal input spring- damping system after animation- quality.)

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.)

主要包含经纬高信息、北天东坐标系、地心坐标系之间的坐标转换，用labview实现的。(It mainly includes the coordinate transformation between the latitude and longitude information, the North East coordinate system and the geocentric coordinate system. It is realized by LabVIEW)

labview FX-3U modbus通信(labview FX-3U communication)

说明：  自己编程的，局部变量用于自锁，用的是虚拟仪器编程软件！(Self-programmed, local variables for self-locking with labview.)

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.)

说明：  文件为Labview的文件存储代码，用于TDMS格式文件存储(The file is the file storage code of Labview, used for file storage in TDMS forma)

使用labview实现中断访问串口，使用消息队列方式传递数据。(Use labview realize interrupt visit, use the message queue serial port style to deliver data. )

使用 labview 编写的控制界面，控制实验室的光谱仪，测量峰值的光功率(spectrum controller)
