摘　　要：随着电子信息技术和计算机技术的高速发展,数据采集应用越来越广泛。提出了一种基于USB接口的数据采集卡的设计解决方案。采用PIC16F886单片机为主控制芯片,PDIUSBD12为USB的接口芯片。给出了采集卡的设计整体框图,并介绍了采集卡的硬件电路设计以及固件程序设计。所设计的USB接口的数据采集卡电路简单、性能稳定,支持即插即用。With the rapid development of electronics and information technology and computer technology, applications of data acquisition become more and more wide. A design of USB interface of data acquisition card is proposed in this paper. The PIC16F886 microcontroller is selected as the main control chip and the PDIUSBD12 chip is selected as the USB interface chip. The design of the overall block diagram of the acquisition card is described. Also the hardware circuit design of the card and the firmware programming design of the card are introduced. USB interface of data acquisition card designed in this paper is simple and stable, and supports Plug and Play.
