摘　　要：针对目前插卡式数据采集卡拆卸不方便,体积较大以及传统单片机控制采集速度低、非实时等一系列缺陷,设计了一套基于FPGA与USB2.0的便携式数据采集系统。系统采用FPGA作为主控芯片,实现对A/D转换芯片及USB2.0接口芯片的控制。利用VC++设计数据采集系统的控制界面,对采集的数据进行显示和存储。该系统小巧、便携的设计特别适用于移动的作业现场。Aimed at the defects of plug-in data acquisition card such as inconvenience to dismount,large size,low control acquisition speed of traditional single chip microcomputer（MCU）,and non-real-time property,a portable data acquisition system based on field programmable gata array（FPGA）and USB2.0 was designed.FPGA was chosen as the main control chip,thus controlling the A/D transition chip and the USB2.0 interface chips.The VC＋＋ is used to design the control interface of data acquisition system,which was used to display and store acquisition data.The system is compact and portable,especially for the mobile spot.
