摘　　要：介绍了一种基于ARM处理器的USB数据采集系统的设计方案,该系统采用了ARMCortex-M3内核的STM32F103作为数据采集终端的微处理器.通过USB实现了数据采集终端与客户端程序间的通讯.经实际测试,整个系统运转正常,最高采样频率为200kHz,满足了预期的数据采集控制与数据传输的要求,并具有可靠性高、实时性强、传输速度快等优点.A design method of data acquisition system for USB was introduced, ARM Cortex- M3 core chip used for STM32F103 was adopted as the microprocessor of the data acquisition terminal,the communication between data acquisition terminal and client program was achieved through USB. The whole system can operate very well in the actual testing. The sampling frequency availabled is 200 kHz,which can meet the expected requirements of data acquisition control and transmission. The data acquisition system has advantages such as high reliability,real time,high transfer speed and so on.
