便携式USB接口数据采集器的开发研究

针对现有PCI数据采集卡的局限性,开发了一种基于USB接口的便携式数据采集器。数据采集器采用了分层开发的思想,设计了完善的应用层协议,同时设计了简明易用的PC机软件。实际应用证实该数据采集器的便携性、即插即用特性具有很高的应用价值。数据采集器的采集通道可以根据实际应用环境进行不同的配置,扩大了应用范围,是科学研究及工程应用领域的有力工具。

Study of A USB Data Acquisition

A USB based portable data acquisition unit is developed in order to eliminate the limitation of PCI data acquisition card. The layering thought of development of data acquisition unit is adopted. The protocol on application level and the PC software are designed. The portability and the feature of "plug and play" is proved to be valuable in application. The acquisition channels of data acquisition unit can be configed in various condition, as a result, it act as a powerful tool for scientific research and industrial application with expanded application domain.
