利用labview语言进行功率谱分析，并得出分析的结果和图形(use labview to analysis Power spectrum )

一个labview的小程序，控制风扇转速的PID控制算法，包括完整的前面板和后面板，和数据采集，采用6008采集板采集数据(Labview a small program, PID control algorithm to control fan speed, including complete front and rear panels, and data collection, using 6008 data acquisition board collection)

说明：  关于labview的一些程序，用于了解机器视觉的(Some programs about LabVIEW)

说明：  用于labview数据库编程，相关指导资料(Used for LabVIEW database programming, related guidance materials)

将需要保存的数据，保存在EXCEL文档或者TXT文档中。(save you need data for excel or txt file,in NI labview entironment.)

利用Labview编写的画圆程序，小巧实用，确定半径和圆心即可(Circle program written with Labview, compact and practical)

对信号进行采集和保存，其采样率默认为信号频率的10倍，并将采集到的信号数据保存到电子表格中(Save signal data acquisition and preservation of the signal, the default sampling rate is 10 times the signal frequency, and collected into a spreadsheet)

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.)

LabVIEW TCP通信实现远程波形通信,可以进行网络控制传输锯齿波、正弦波等。(LabVIEW TCP communication realizes remote waveform communication. It can carry out network control transmission sawtooth wave, sine wave and so on.)

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(Labview design using a virtual function signal generator, data acquisition card output waveform signal,)
