摘要
充分利用高速通用串行总线(USB)所具有的传输速度快、支持热插拔、即插即用易于扩展、占用的系统资源少等优点,将其与传统的数据采集技术相结合,设计实现了一种基于USB的数据采集系统。本文首先对USB2.0总线技术进行了介绍,然后详细介绍了一种基于USB2.0接口技术的数据采集系统,包括数据采集系统设计、固件设计、设备驱动程序设计和主机应用程序设计。本文完成的基于USB总线的数据采集系统,为数据的采集提供了一种更有效、更经济、更方便的数据采集方式。
A new kind of data acquisition system which is based on USB （universal serial bus） technology is designed in this paper. The advanced performance of USB with high-speed, hntplug, plug and play, easily to expand and engrossing less system resource is shown in the system. USB2.0 bus technology is introduced in this paper firstly. Then the design of the data acquisition system is discussed in detail in there are four parts： data acquisition system design, firmware design, device driver and application program. The data acquisition system based on USB bus provides a more effective, more economical and more convenient way to collect data.
