USB串行总线数据采集卡的实现

The achievement of USB serial bus data collection card

介绍了通用串行总线(USB)专用接口控制芯片及内部结构。并基于串行总线的实时数据采集系统,严格遵守USB1 1协议,具体设计了数据采集卡。同时充分体现了USB系统总线的便捷、易扩展、低成本、抗干扰的特点。

This paper introduces the allpurpose serial bus,special interface control chip and their internal architecture.The realtime data collecdtion system based on serial bus abides by strictly USB1.1 Protocol and designs the data collection card concretely,moreover,it incarnates enough the features of USB system bus such as convenience,easy extension,lower cost and registry disturb.
