摘　　要：为了提高实际数据采集的速度,保证数据采集的实时性,设计了此高速数据采集系统。本文以Cypress Semicon-ductor公司的EZ-USBFX2系列的CY7C68013芯片作为核心芯片,主要叙述了整个高速数据采集系统的硬件设计,同时将USB连接技术引入到测试测量中,研制了一套接近实用的便携式高速数据采集系统。通过USB2.0接口,实现了数据的实时高速采集,保证了采集的效率。In order to improve the speed of data acquisition in practice, ensure the instantaneity of data acquisition, the witer designs this high speed data acquisition system. The paper taking cypress semiconductor’s EZ-USB FX2 series of CY7C68013 as the core chip, hardware design of the high-speed data acquisition system is described,in the meantime, introduces the technology of USB connection in the test and measurement, developed a close to practical portable high-speed data acquisition system. Through USB2.0 interface, the system achieves the instantaneity data acquisition,and ensures the high efficiency of the collection.
