摘要
USB通用串行总线通信技术由于其使用方便、速度快及连接灵活和独立供电等特点,已得到了越来越广泛的应用,文中以速度跟踪系统中的数据采集作为实例将其引入工程应用中。简述了USB串口通信的特点,介绍了USB设备管理与数据采集的相关函数。重点详细地介绍了数据采集的工作流程,并以具体实例从软件的角度演示了数据采集的全过程。
USB communication technologies because of its easy to use, fast and its flexible and independent power supply, obtained the more and more widespread application. In the actual project application day by day was also widespread, introduced its engineering apphcation by the data collection on speed tracking system. It has summarized the USB string port communication characteristic, introduced the USB equipment management and the data collection correlation hmction, key in detail, introduced the data collection process, and has demonstrated the data collection entire process by the specific example in software.
