数据采集编程指南 中篇

说明：  labview五子棋小游戏，可以来看看哦，、很不错(With the continuous improvement of living standards, people no longer sati-sfied with just material life, leisure time people will choose your favorite enter-t-ainment used for recreation.)

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..)

Labview的3D控件的功能介绍，还有三个例子程序：陀螺仪，2D魔方，3D魔方。(Function Labview 3D controls introduction, there are three examples: gyroscope, 2D Rubik' s Cube, 3D cube.)

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.)

一个简单的声音采集系统，有声音采集和声音回放功能，还可以将采集到的声音在时域频域进行分析(A simple voice acquisition system has the functions of voice acquisition and playback. It can also analyze the collected voice in time domain and frequency domain.)

齿轮箱故障诊断的一些集成程序 可以实现齿轮箱的常见分析(Gearbox Fault Diagnosis of some integration program can achieve a common analysis of the gearbox)

利用labview编程和数据库连接起来，实现对数据的存储与读取(ligner with labview)

说明：  LabView关于USRP开发例程，可以通过连接USRP进行简单的信号传输，并对IQ信号进行操作(LabVIEW about the USRP development routine.You can connect USRP for simple signal transmission and IQ signal operation)

LabVIEW环境下动态载入技术，个人编写的，在8.5版本下可以运行，很好的！(LabVIEW environment, dynamic loading technology, personal written version may be run at 8.5, very good!)

安捷伦频谱仪labview仪表控制代码，包括仪表面板上个按钮操作对应的控制子Vi和一个模拟仪表面板的主Vi(The Agilent spectrum instrument LabVIEW instrument control code, including the control sub Vi of the button operation on the instrument panel and the master Vi of an analog instrument panel)
