说明：  labview中常常需要显示曲线，并需要制作缩放，设置，浮动游标等功能。本Xcontrol集成了这些功能，这样就不用每次都去写麻烦的曲线操作了！(LabVIEW often needs to display the curve, and needs to make zoom, set, floating cursor and other functions. This XControl integrates these functions, so you don't have to write troublesome curve operations every time!)

本设计采用NI PCI-6221数据采集卡，运用虚拟仪器及其相关技术于多通道数据采集系统的设计。该系统具有数据同时采集、采集数据实时显示、存储与管理、报警记录等功能，最后使用Web技术实现了采集数据的远程访问(This project use NI PCI-6221 DAQ(data acquisition) card,ingeniously applyes VI technology in the development of a Multi-channel data acquisition develoment and finally achieves a solution which can provide many functions including multi-channel and multi-parameter signal acquisition,huge measurement information storage and management,Alarm record, and Collecting data show that real-time.Finally the use of Web technology to achieve the Acquisition of data remote access.)

基于LabVIEW设计的绘制任意系统的Nyquist曲线和Bode图，适合学习控制理论的同学巩固和复习理论知识。(Nyquist and Bode diagram based on LabVIEW curve design draw any system for learning control theory to consolidate and review the students theoretical knowledge.)

利用LabVIEW的Active X模块以及STK的Connect 模块实现两种软件交互的方法，通过LabVIEW 的Active X功能连接STK，利用Connect模块中的指令驱动STK产生卫星的相关数据，最终将有关数据返回至Lab VIEW中并显示出来，实现了Lab VIEW与STK的无缝连接(Design of a Satellite Orbit Prediction Visualization Platform Based on Lab VIEW and STK A method of designing a satellite orbit prediction visualization platform based on a hardware-in-loop validated simulation system of small satellite is introduced． Satellite Tool Kit is an analysis software widely used in simulating orbit system for satellite ， but STK can’t accomplish the relevant function that acquired by the hardware- in-loop validated simulation system mentioned． Based on this requirement ， a method of using Active X technology in Lab VIEW and STK/Connect module to interact the two kinds software is introduced． Through calling STK and u- sing Connect module in STK to obtain the relevant data ， finally all the datas in need within a window synchronously can be displaied ， which realized the connection between Lab VIEW and STK ， also accomplished the relevant func- tion and has a applied value． )

labview的pid控制程序数据库资源。内容丰富(LabVIEW pid control procedures database resources. Rich in content)

labview与OPC通讯以欧姆龙NJ501PLC为例，希望能对大家有帮助。(Labview communicates with OPC)

LV6例如为高级扫描2700，2701，2750（使用IVI驱动程序）(LV6 example for Advanced Scanning with 2700, 2701, 2750 (uses IVI driver) )

说明：  LABVIEW的BP神经网络曲线拟合程序(the BP ANN exe based on LABVIEW )

基于LABVIEW虚拟仪器设计的多通道数据采集系统，利用DAQ助手编译，可实现PC机上的数据实时监控及记录(labview daq)
