LabVIEW-bao-dian

基于Labview的数字电压表的设计,可用(ji yu LABview de shuzi dianya biao de she ji )

此程序是基于labview的tcp/ip控件设计的多功能聊天软件，类QQ，可以进行文本、图片、文件等传输，可以在局域网、广域网内进行传输，具有很好的适用性，可以进行课程设计或毕业设计(This procedure is based on the labview tcp/ip control design versatility chat software, classes QQ, can be text, images, documents, etc. transfer, can be transmitted within a LAN, WAN, with good applicability and can be curriculum design or graduation)

用LabVIEW编制一个完整应用软件，完成以下功能： 1、产生一个正弦波，叠加一个噪声信号，从界面上可以调整噪声和信号的幅度、频率等参数，此信号作为后续分析的信号源； 2、显示信号的时域波形，点击按钮可以显示信号的幅度谱、功率谱 3、图形上可以显示光标，具有峰值跟踪功能，同时将峰值频率、幅度显示在界面上。 4、点击按钮可以计算显示信号的失真度（THD）、信噪比（SNR）、各次谐波的频率和幅度；(Preparation of a complete application using LabVIEW software, perform the following functions: 1, generates a sine wave, the superposition of a noise signal, the interface can be adjusted from the noise and the signal amplitude, frequency and other parameters, this signal as a follow-up analysis of the signal source 2. time-domain signal waveform display, click the button to display the signal amplitude spectrum, power spectrum 3, you can display a cursor on the graph, with a peak tracking, while the peak frequency, amplitude displayed on the screen. 4, click the button to display the calculated distortion (THD) signal to noise ratio (SNR), each harmonic frequency and amplitude )

LabVIEW里实现服务器功能，后面还有客户机(server)

说明：  用于读取txt文本文件，并显示在labview中(Used to read the numbers in the txt file and display them in LabVIEW)

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.)

本系统开发采用NI公司的LabWindows/CVI开发环境编写（Windows操作系统），本系统完成基于ANSI C标准来编写。可以实现虚拟温度的采集与回放。(The system development using NI s LabWindows/CVI development environment, (Windows operating system), this system was completed to prepare based on the ANSI C standard. Allows the collection and playback of virtual temperature.)

说明：  关于图像采集和处理的实际例子，适合新手学习学习(grab image and processing)

labview环境下实现emd分解，而且是无密码的版本(labview environment to achieve emd decomposition , and is the version without a password )

说明：  登陆界面，能够实现对用户的注册，以及管理员能够对数据进行操作(The login interface enables users to register and administrators to manipulate data.)
