LABVIEW prepared by the NI timing synchronization control card, control the camera synchronized shooting

In this program we put any temperature and the program will show us with booleans if there is a problem about the temperature

在LabVIEW环境下实现全景照相。在手动转动摄像头前提下，程序实现图像拼接，照片保存。(BASED on LabVIEW the program can achieve the function which panoramic camera can do,besides, it can also let you save your photos in your hardwire while your camer is connect with the computer)

在NI LabView平台上结合TCP/IP协议进行数据传输的工作方法，并给出对工业现场数据采集传送与监控的仿真实例(NI LabView platform combined with TCP/IP protocol for data transmission methods, and simulation examples are given on the transmission and monitoring of industrial field data collection)

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..)

本文主要介绍了利用国产普通数据采集卡，基于美国 NI 公司提供的虚拟仪 器软件开发平台 LabVIEW 和实验室原有发动机硬件平台自行开发的一套气缸压 力采集模块和数据分析模块(This thesis primarily introduced software about cylinder pressure and crank angle acquisition and data analysis module. It is designed by using a general data acquisition board, which is based on Virtual Instrument LabVIEW offered by NI and laboratory engine. )

字符串转十六进制的labview源程序vi,可以作为子VI加入到自己的程序中去。(LabVIEW source string to hexadecimal vi, can be used as a sub-VI added to the program to go.)

将摄氏度转化为华氏度。用户给出一个摄氏度温度数值，程序自动将其转化为华氏度值。(Degrees Celsius into Fahrenheit. The user is given a degree Celsius temperature value, the program will automatically convert to Fahrenheit value.)

利用LABVIEW开发环境，实现GPIB串口通讯(无)

labview中用程序去产生一个触发事件是个难点，相关的介绍和例子并不多，本程序使用值属性信号结点改变的方法去产生一个事件，实现程序控制产生触发事件的功能，labview开发版本8.2。(labview using the program to generate a trigger event is difficult, relevant examples of the introduction are not many,here we use the value change of the node attribute of the signal to generate an event, the realized the program control functions to generate trigger events, the version of labview development is 8.2 .)
