本文主要介绍了利用国产普通数据采集卡，基于美国 NI 公司提供的虚拟仪 器软件开发平台 LabVIEW 和实验室原有发动机硬件平台自行开发的一套气缸压 力采集模块和数据分析模块(This thesis primarily introduced software about cylinder pressure and crank angle acquisition and data analysis module. It is designed by using a general data acquisition board, which is based on Virtual Instrument LabVIEW offered by NI and laboratory engine. )

基于LabVIEW设计的绘制任意系统的Nyquist曲线和Bode图，适合学习控制理论的同学巩固和复习理论知识。(Nyquist and Bode diagram based on LabVIEW curve design draw any system for learning control theory to consolidate and review the students theoretical knowledge.)

说明：  使用LABview制作的接收TCP协议的温湿度数据的上位机(Host computer of receiving temperature and humidity data of TCP protocol made by LabVIEW)

LabVIEW编写的一个信号发生器程序，可选择正弦波、方波、三角波等(A signal generator program written by LabVIEW can select sine wave, square wave, triangle wave, etc.)

本代码编制测距传感器的串口通讯接口VI；通过波形图表显示连续读取的测距-时间曲线，并将有效测量范围外的数据滤除。(This code compiles the serial communication interface VI of ranging sensor, displays the continuous read ranging-time curve through waveform chart, and filters out the data outside the effective measurement range.)

使用labview制作而成的网页浏览器，输入网址即可打开网页(Web browsers made with LabVIEW)

可以对单次输入的信号进行滤波分析和图像显示。同时也具备暂停和历史图像保存的功能。 本程序主要针对的是低频率的未知信号，对于高频率信号最好采用单次采样的方式。(The single input signal can be filtered and analyzed, and the image can be displayed. It also has the functions of pausing and preserving historical images. This program is mainly for low frequency unknown signals, for high frequency signals, the best way to use a single sampling.)

对LabVIEW进行二次开发，对信号进行聚合经验模态分解(To LabVIEW second development, the signal to carry out the polymerization of empirical mode decomposition)

说明：  可以将acces数据库中文件导入到excel表格中(updata the data from access to excel)

labview调用动态链接库相关说明文档，及调用PMAC动态链接库Pcomm32.DLL的例程(labview called dynamic link library-related documentation, and call PMAC dynamic link library routines Pcomm32.DLL)
