基于USB设计的数据采集处理系统

Data acquisition and process system based on USB transmitting

一种基于USB传输的数据采集及处理系统的设计和实现,包括USB接口的工作原理,接口芯片的连接方法和单片机端的数据采集方法。同一般的数据采集系统相比,本系统数据传输快、误码率低,且该套方案实施容易,稳定可靠,为研究数据采集与数据处理提供了方便。

How to design data acquisition and process system based on USB Transmitting. We further introduce some system＇s structure such as Operation principle of USB,application method of Interface chip,the method of data collected by MCU. To compare with general data acquisition system, it has the characters of fast speed and low bit error rate. This method is reliable and easy to implement. And it brings a lot of convenience for the research of data acquisition and process system.
