能够保存采集数据，保存到excle文档，以便于采集后数据保存(saving the collected data and save it to the excle document)

清除串口冗余。当下位机偶然有乱码出现时，在新的通讯开始先清除缓冲区冗余信号，然后开始通讯，可以保证通讯更稳健(Clear serial redundancy. Current-bit machines have occasionally garbled when, in the new communications start to clear the buffer zone redundant signal, and then began to communications, to ensure more robust communication)

串口数据采集RS232串口是工业中比较常用，也最容易接触到的一种总线协议，台式机上一般都有二个，而现在很多下位机、仪器等很多都还是使用串口通信的。通过RS232串口可以方便的实现Labview与其他测试软件、控制软件的通信。(Serial port data acquisition RS232 serial port is a kind of bus protocol which is commonly used in industry, and it is also the most easy to contact. In general, there are two desktop computers, and many lower computer, instrument and so on are still used in serial communication. The communication between Labview and other test softwares and control software can be conveniently realized through RS232 serial port.)

绝对平均值是计算波形指标与脉冲指标的重要参数。本文件中将其独立制作成了一个子VI，方便labview程序调用。(The absolute mean value is an important parameter to calculate the waveform index and pulse index. This document will be independently produced into a sub VI, to facilitate the LabVIEW program call.)

基于labVIEW的最小二乘法算拟合正弦波计算相位(Calculated based on least squares fitting labVIEW calculated phase sine wave)

“信号处理实验室”是由NI开发，针对信号处理、信号与系统、通讯原理等课程量身订做的课程套件，其中包括了卷积、混叠、窗函数分析、栅栏效应、IIR、FIR、AM/FM调制、倒谱等等50多个从基础到高级的信号处理知识点的演示程序。有助于教学演示使用，帮助学生理解。(The signal processing laboratory was developed by NI, according to the course of signal processing, signal and system, communication principle and customized courses package, including convolution aliasing, window function analysis, IIR, FIR, barrier effect, AM/FM modulation cepstrum more than 50 from basic to advanced signal processing knowledge presentation program. Help the teaching demonstration use, help the student understand.)

说明：  电机控制器的串口通信界面,基于labview visa,德马克电机(Serial communication interface of motor controller based on LabVIEW visa, demarcation motor)

说明：  labview下实现16进制转换浮点数。(In LabVIEW, the conversion of hexadecimal floating-point number is realized.)

基于labview的数据采集与回放系统。通过labview编写了一个关于噪声信号的采集与回放及处理的系统。(Data acquisition and playback system based on LabVIEW)
