1. 一个完整数据采集系统的基本组成部分 2. NI 提供了基于哪些平台的数据采集硬件产品，它们分别适用于什么样的应用领域 3. 数据采集设备硬件选型过程中应该关注哪些重要参数(Introduction of NI data acquisition hardware 1. Basic components of a complete data acquisition system 2. NI provides data acquisition hardware products based on which platforms and which application areas they are suitable for respectively. 3. What important parameters should be paid attention to in the process of hardware selection of data acquisition equipment)

基于labview串口保存数据 下位机发送的数据经过labview自动保存。 实测可用(Based on the data stored labview serial data sent through the next crew labview automatically saved.)

通过labview控制信号发生器和锁相放大器进行共振频率检测的程序。freq test.vi实现信号发生器的频率扫描，lockin test.vi 实现锁相放大器的参数设定，数据采集.vi实现锁相数据的采集，waveform arrays to file实现波形数据到文件数据的转换。共振频率测试.vi实现晶振等共振频率的测试(Resonance frequency detection procedures performed by labview control signal generator and lock-in amplifier. freq test.vi achieve frequency sweep signal generator, lockin test.vi setting parameters to achieve lock-in amplifier, a data acquisition. vi achieve phase lock data acquisition, waveform arrays to file converted waveform data to achieve document data. The resonance frequency of the test. Vi achieve crystal and other resonant frequency test)

温度处理系统，温度显示模块 温度报警功能(daq )

说明：  基于labview的串口通信程序，可通过串口向下位机发送不同的指令(The serial communication program based on LabVIEW can send different instructions to the lower computer through the serial port)

labview好看的自定义控件，NI风格。(LabVIEW nice custom controls)

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.)

傅里叶变换 LabVIEW的源码 希望对广大学习有些帮助 (Fourier transform LabVIEW source code hope the majority of learning some help)

使用labview实现了FFT的变换，此方法更为简单快捷，同时简单明了(Labview achieved using FFT transform, this method is more simple and quick, and simple)

对电机进行手动控制，改变电机转速完成实验教学演示目的 (Manual control of the motor, changing the motor speed to complete the experimental teaching demonstration purposes)
