说明：  本项目是以 LabVIEW 为开发平台的环境监控与预警系统，实现了对温度，烟雾和电压电流等信号的实时采集、记录、存储和回放等功能程序的模块化设计，从而达到环境监控的目的。(This project is an environmental monitoring and early warning system based on LabVIEW. It realizes the modular design of functions such as real-time acquisition, recording, storage and playback of signals such as temperature, smoke and voltage and current, thus achieving the purpose of environmental monitoring.)

说明：  该文件是labview实现例子，写入和读取二进制文件。(This file is an example of LabVIEW implementation, writing and reading binary files.)

FOR循环计算0——99偶数的和，用到for循环以及移位寄存器(FOR loop calculates the sum of 0-99 even numbers, using for loop and shift register)

基于LABVIEW软件采集电压电流信号，运用DAQmx建立任务(Acquisition of voltage and current signals)

labview实现双通道数据采集回访系统，能够对采集到的数据进行回放分析(LabVIEW dual-channel data acquisition reciprocal system can playback analysis of the data collected)

优点：1，PPI协议通讯速度快，比OPC ，PCAccess，Modbus 快4-5倍左右。(就这一条优点就足了，呵呵) 2，PLC端无需编写任何通讯程序。 3，可以直接对PLC进行，RUN STOP等操作。 4，本程序全部采用LABVIEW底层程序框图，没用调用任何的DLL ，API等。这点对你学习还是修改程序功能都很有帮助，方便。 (Advantages: 1, PPI protocol communications faster than OPC, PCAccess, Modbus about 4-5 times faster. (On which an advantage on the feet, huh, huh) 2, PLC-side without writing any communication program. 3, can be carried out directly on the PLC, RUN STOP operation. 4, the procedure used in all LABVIEW underlying the block diagram, useless to call any DLL, API, etc. This is for you to learn or modify the program features are very helpful and convenient.)

利用DAQ助手实现的基于LABVIEW的示波器，可通过数据采集卡实现各种波形显示和尺度调节(Use the DAQ Assistant to achieve based on the LABVIEW the oscilloscope, data acquisition card to a variety of waveform display and adjust the scale)

This program compute the average filter of an image using the vision assistant

欢迎学习Matlab和Simulink的控制教程。它们旨在帮助您学习如何使用Matlab和Simulink来分析和设计自动控制系统。它们涵盖了Matlab和Simulink的基础知识，最常见的经典控制设计技术（PID、根轨迹和频率响应），以及一些现代（状态空间）控制设计和数字控制。教程的流程由主页上的图像映射给出：每个教程都是一个位于左侧的框。还有七个示例，这些示例将贯穿教程（每个示例页在图像地图中用一个点表示）。在整个教程中，您将在每个页面的底部找到指向所有教程的链接，以及指向类似示例的链接。还提供了返回主页、完整索引以及matlab命令和simulink块列表的链接。(Welcome to the Control Tutorials for MATLAB and Simulink. They are designed to help you learn how to use MATLAB and Simulink for the analysis and design of automatic control systems. They cover the basics of MATLAB and Simulink, the most common classical control design techniques (PID, root locus, and frequency response), as well as some modern (state-space) control design and digital control. The flow of the tutorials is given by the image map on the home page: each tutorial is a box along the lefthand side. There are also seven examples which are followed through the tutorials (each example page is indicated in the image map by a dot). Throughout the tutorials, you will find links at the bottom of each page to all of the tutorials as well as links to similar examples. Links are also given to come back to the home page, to the complete index, and to the list of MATLAB commands and Simulink blocks.)

.用产生三种不同波形，分别计算并显示它们的单边频谱及功率谱，显示低通、带通、带阻、高通四种不同的滤波效果，体会滤波器的使用。(Three different waveforms are produced, and their single side spectrum and power spectrum are calculated and displayed respectively, which show four different filtering effects, such as low pass, bandpass, band resistance and high pass, and realize the use of the filter.)
