数据采集编程指南 下篇

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.)

232串口通信实例，简单的模仿USB界面显示，实质做的是一个简单的232串口(232 serial communication)

包络检波的小程序，基于labview的程序(Envelopment analysis Applets do withThe research trend of fiber-optic sensing based on BOTDR technology has been introduced with particular attention to signal processing. The sensing principle using Brillouinscattering has been analyzed and the dependences of Brillouin shift and intensity on temperature and strain have been founded.)

说明：  Labview使用OPC和其他PLC通讯配置方法步骤。(LabVIEW uses OPC and other PLC communication configuration method steps.)

说明：  Stanford Research 830 Acquire Measurement 用于锁相放大器的单个参数，多个参数，多点的测量(Stanford Research 830 Acquire Measurement for single parameter, multiple parameter, multi-point measurement for PLA)

说明：  虚拟示波器的设计， 基于LabVIEW的虚拟示波器设计 (Virtual Oscilloscope)

说明：  利用labview实现登录和修改密码（账号密码在txt文本文件中）(To sign in and change password)

虚拟仪器高级应用全书例子，用的C语言开发环境Labwindows/CVI，有各种高级应用的例子，非常值得学习参考。(Virtual instrument advanced application book example, using the C language development environment Labwindows/CVI, there are a variety of advanced application examples, it is worth learning reference.)

利用Labview采集8路信号数据，带注释(Using Labview to collect 8-channel signal data with annotations)

用LabView制作的一个可乐售卖机小程序。(A small program of Coke vending machine made by LabView.)
