基于LabVIEW的通用自动测试系统设计

labview实现网络摄像头的图像采集，通过TCP/IP协议采集摄像头的图像，这是我在实际监控安防项目中用到的，绝对可以使用。(The LabVIEW realizes the image acquisition of the network camera, and collects the image of the camera through TCP/IP protocol. This is what I used in the actual monitoring and security project. It can be used absolutely.)

labview生成随机数并且读取后存储显示出来(Labview generating random Numbers and read after the store display)

Labview，数据采集例程，带子VI，(Labview, data acquisition routines, have SubVI)

word、excel报表工具，适用于8.5以上所有版本，可实现word、excel读写。(word, excel reporting tools for all versions above 8.5 can be realized word, excel read and write.)

基于LABVIEW的虚拟频谱分析仪，可以对任意信号以及采集卡采集到的信号进行频域分析，同时还加入了时域分析，使功能更为强大。(LABVIEW-based virtual spectrum analyzer can be arbitrary signals and the signal acquisition card for frequency domain analysis, and also joined the time-domain analysis, so that more powerful.)

显示了对labview中FFT频谱、频响、和频谱测量三个vi的区别。(Shows the difference for labview in FFT spectrum, frequency response, and spectral measurements three of vi.)

VISA module 2 for serial communication

labview程序，可以接收和发送modbus rtu协议信息。“CRC VHL”为循环冗余校验(Labview program)

设置电源的电压值的控制程序，可以实现电源的任意给值，和开关控制(Setting the voltage value of the power supply control program, can achieve any of the power supply to the value, and a switch control)

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..)
