13.LabVIEW-rs232

说明：  利用Labview编程调用函数库实现FFT快速傅里叶变换功能(FFT based on Labview)

本程序基于LABVIEW对能量谱进行了分析和计算，程序简单，实用(Used for the calculation of energy spectrum)

建议实现BP神经网络的Labview程序，主要还是用做学习，工程实际还有所欠缺(We recommend implementing programs Labview BP neural network, learning is mainly used in engineering practice are lacking)

USRP demo using labview

使用matlab直接读取tdms数据，不需要转换，没有错误。(TDMS reads matlab program)

本文主要论述了基于LabVIEW 的身份验证登录程序的设计与实现原理, 讨论了建立用户信息数据库以及LabVIEW与数据库的连接方式的选择,LabSQL工具的应用,实现了根据用户信息数据库进行身份验证的功能, 符合数据库信息的用户方能成功登录, 可以方便地嵌入已有的以LabVIEW 为开发工具的测控系统中。(This paper discusses the design and realization of the principle of identity validation based on LabVIEW login program, user information database as well as the choice of LabVIEW and database connections, LabSQL tool applications based on the user information database authentication user database information can be successfully logged and can be easily embedded the existing LabVIEW as the development tool measurement and control system.)

LABVIEW下实现自动的EMMD分解，广泛应用于故障诊断系统 (The LABVIEW under to achieve automatic EMMD decomposition, widely used in fault diagnosis system)

几个练习使用Labview编程的产物，主要包括：1.正弦扫频信号发生器，可选择频率变化规律（不变、线性、指数变化）以及幅度变化规律（不变、线性、指数变化），还可以通过MathScript节点自定义频率、幅度变化规律； 2.声卡数据采集及频谱分析；3.会说话的小圆点；4.十六进制数布尔数组显示；5.在字符串中显示多种字体；6.钢琴键盘模拟(Several products by practicing Labview programming, including: 1 Sine sweep signal generator, selectable frequency variation (constant, linear, exponential change) and amplitude variation (constant, linear, exponential changes), you can also customize the frequency and amplitude variation through MathScript Node 2 sound card data acquisition and spectrum analysis 3 talking dots 4 hexadecimal to boolean array display 5 display a variety of fonts in the string 6. Piano keyboard simulation )

模拟多种信号的产生，频率和幅值可调，并显示波形。(A variety of signals are simulated, the frequency and amplitude are adjustable, and the waveform is displayed.)

labview中实现前面板的打印，打印格式为PDF.通过设置VI的属性实现报表打印(achieve labview front panel printing, print format is PDF. realized by setting the properties of print statements VI)
