摘要
介绍了USB的关键技术及其在计算机数据采集中的应用。通过采集装置实时采集长直螺旋管的磁场强度,并通过CY7C68013A的USB传输给PC机,使PC端能在线分析磁场分布。实验表明,该装置具有即插即用、高速度、高实时性等特点,可广泛用于工业生产和教学实验中。
The application of USB technology in data Acquisition is introduced in the paper. The magnetic field of the long is acquisitioned with the data acquisition device and transported to PC by CY7C68013A. It enables PC analyze magnetic field measurement on line. It is proved by the experiment that it has characteristics of plug-and-play, high-peed and high real-time performance, and can be widely used in industrial and experimental teaching in the university .
