labview--PMAC-Pcomm32

有关labview 的串口通信，实时显示数据，并且进行后台保存，输出文件(about labview serial com interfce communication ,diaplay data timely and save it behind )

labview internet connect tool(PC internet connect tool)

Labview常用板卡驱动，在厂家原有驱动上进行了二次包装，具体包括Agilent（3352X、 34970、DSO1012A）艾德克斯直流电源、凌华（PCI7256、PCI8554、PCI9113）神州飞航（AECCP32ADM、AECDAC8、AECIOC96、AECPDA32）本人水平有限，各位凑合着用。(Labview driver card used in the original manufacturers were driven on secondary packaging, specifically including Agilent (3352X, 34970, DSO1012A) ITECH DC power, Adlink (PCI7256, PCI8554, PCI9113) Shenzhou flight (AECCP32ADM, AECDAC8, AECIOC96, AECPDA32) I level is limited, you make do with.)

1．采用Labview设计一虚拟函数信号发生器， 通过数据采集卡输出波形信号，调节信号的相关参数，可观察示波器上波形的变化情况。 ⑴ 以NI MyDAQ数据采集卡作为输出接口； ⑵ 数据采集卡输出多种信号，至少完成三种波形：正弦波、三角波、方波(可调占空比)的输出，同时前面板上显示各输出波形； ⑶ 频率、幅值、初相位、直流偏移量和方波的占空比（0～100 ）等参数可以通过前面板控件调节。 ⑷ 前面板可显示输出波形。(1. Labview design using a virtual function signal generator, data acquisition card output waveform signal, adjust the relevant parameters of the signal can be observed on an oscilloscope waveform changes. ⑴ with NI MyDAQ data acquisition card as output interface ⑵ data acquisition card output a variety of signals, to complete at least three waveforms: sine wave output, triangle wave, square wave (adjustable duty cycle), while each of the output waveform is displayed on the front panel ⑶ frequency, amplitude, initial phase, the DC offset and duty cycle square wave (0 to 100 ) and other parameters via the front panel controls to adjust. ⑷ output waveform can be displayed on the front panel.)

labview实现对变压器局方数据的采集及后期处理，如根据局放数据实现局放定位等。(The labview achieve transformer Bureau data acquisition and post-processing, such as PD the data realization PD positioning.)

说明：  labview很重要的例程，适用于labview新手(it is very important for the new student of labview ,very usful)

labview串口的队列接收方式，有效解决labview串口接收时字节错乱问题(labview visa queue send and receive)

Webcam vi as an example

Dialog Config Timer with Serial port

说明：  基于.Net的DirectShow LIB包，可以用于Labview调用DirectShow，实现对相机的控制(The. Net-based DirectShow LIB package can be used to call DirectShow by Labview to control the camera.)
