【正文】 ion system based on USB .single chip programs the fireware to the USB interface chip— ISP1581。 lots of data from the industry spot are printed, analyzed and disposed on time. On the base of wonderful understanding to USB protocol and device truss, I finish the hardware design and software programme of the data collection system. And draw the principle this data collection system， we can understand the USB protocol profoundly and apply the interface chip ISP1581 proficiently. In all, the advantages of this interface technique may helps to your design arrangement. Key words： USB bus； data collection； fireware； WDM； device drive program 目 錄 摘 要 ...............................................................
