利用labview语言进行平均值的滤波分析，并得出分析的结果(use labview to achieve the average value filter)

5124采集程序，频谱显示，时域波形显示，存储，通道之间的相位差计算(5124 collection procedures, spectrum display, time-domain waveform display, storage, compute the phase difference between channels)

说明：  使用labview接收串口数据并显示出来，波特率可以设置。(Using LabVIEW to receive serial data and display it, the baud rate can be set.)

利用Labview平台，实现了指定格式的xml与xls文件的互转功能，其中xml端利用Labview内部函数，xls端利用下载的dll函数。虽然不是通用互转系统，但仍然对labvie环境下xml编程和excel编程很有帮助。(The the Labview platform to achieve a specified format xml with the xls file Huzhuan function, in which the xml end to using Labview internal function, xls to end the use of the downloaded dll function. Although not the Universal Huzhuan system, but still helpful the xml programming labvie environment and excel programming.)

说明：  故障检测，火车故障检测系统，labview实现(Fault detection, train fault detection system, LabVIEW implementation)

选择文件路径读取TDMS文件，选择是否校准，选择数据组名及通道名，对数据进行频谱分析(Spectrum analysis of the data from TDMS file.)

利用Labview采集8路信号数据，带注释(Using Labview to collect 8-channel signal data with annotations)

锁相技术在测控、通信、数字信号处理等众多领域得到了广泛的应用。虚拟锁相环成为锁相环发展趋势之一，根据锁相环路的基本组成及原理，利用LabVIEW软件提供的强大的数值计算和信号分析等能力对锁相环进行设计。实验和仿真结果表明该软件锁相环具有较好的捕获和跟踪性能。利用软件实现的锁相环比硬件锁相环具有更好的灵活性和通用性，同时具有结构简单、参数设计灵活等优点。(Lock-in technique in many areas of monitoring and control, communications, digital signal processing, has been widely used. Became one of the virtual phase-locked loop phase-locked loop trends, according to the basic principles of composition and phase-locked loop, using LabVIEW software provides powerful numerical calculation and signal analysis capabilities such as phase-locked loop design. Experimental and simulation results show that the software PLL has a better acquisition and tracking performance. Use of software than hardware locked loop PLL has better flexibility and versatility, but also has a simple structure, flexible design parameters, etc..)

创建一个vi，实现对按钮状态的指示和按钮“按下”持续时间的简单计算功能，按下按钮时，对应的指示灯亮，对应的数字量显示控件中开始计时。松开按钮时，指示灯灭，计时停止。(Create a VI to realize the instructions of the button state and the simple computing function of the button "press" the duration. When the button is pressed, the corresponding indicator lights up, and the corresponding digital quantity displays the timing in the control. When the button is loosened, the light is put out and the timing is stopped.)

该文件是labview实现例子，写入和读取二进制文件。(This file is an example of LabVIEW implementation, writing and reading binary files.)
