中文摘要：

介绍了一套基于PMD-1208LS数据采集卡和基于LabVIEW的PC数据采集系统，系统采用PMD-1208LS数据采集卡，通过USB接口与PC机相连，利用软件平台LabVIEW建立温度数据采集系统并进行数据传输，以实现信号从采集到显示（波形显示和数据列表显示）、存储和回放。本数据采集系统采用美国MCC公司生产的数据采集卡PMD-1208LS实现数据的高速实时传输与处理。在PC机上运用虚拟仪器能共享硬件和软件资源，快速、方便地组建各种数字信号处理系统，并可借助计算机的功能，进行数据处理、存储以及图形化显示等。经过实验检测，基本达到了数据采集、处理、存储和回放的目的，并且使用方便、直观。

英文摘要：

Introduce a set of PC data acquisition system based on PMD-1208LS data acquisition card and LabVIEW,the system adopts the PMD-1208LS data acquisition card,through the USB interface PC machine is linked together,using LabVIEW software platform to establish the temperature data acquisition system and data transmission,so as to realize the signal from acquisition to display （ waveform display and data list display） ,storage and playback. The data acquisition system uses the MCC producting data acquisition card PMD-1208LS to realize high speed data real-time transmission and processing. In the PC using virtual instrument can share hardware and soft-ware resources,fast and convenient to set up all kinds of digital signal processing system,and by means of the function of the computer to finish data processing,storage and graphical display,etc. After the test,reached the data acquisition,processing,storage and playback basi-cally,and easy to use and intuitive.
