摘　　要：针对工业生产中使用的低成本数据采集装置同样需要高速、可靠传输来采集数据的要求,研究并设计了一种基于ARM7内核微处理器S3C44B0X的嵌入式USB数据采集模块。利用S3C44B0X内置8路10位模数转换器,通过对USB协议及硬件模块、嵌入式操作系统μC/OS-Ⅱ的深入研究,完成了S3C44B0X最小系统以及与USB硬件的接口电路等硬件设计,将μC/OS-Ⅱ成功移植到S3C44B0X微处理器,最终实现了该嵌入式数据采集模块的整体可靠运行。经实际检测、使用,该模块具有高性能、低功耗、低成本的优点,实用价值较高,可作为基本模块器件嵌入应用于多种数据采集传输场合。To get a kind of data acquisition device with the requirements of low cost, high speed and reliable data-transmission which applied in industry production, a special embedded USB data acquisition device which based on ARM7-kernel Microprocessor S3C44BOX is designed after studying USB protocols, embedded operating system μC/OS-Ⅱ and related hardware. Minimum system of S3C44BOX and its interface circuit with USB hardware controller are designed, and μC/OS-Ⅱ is transplanted successfully. Depending on the inner eight ten-bit A/D converter of S3C44BOX, the embedded data acquisition device is realized. The research results indicate that this kind of cleviee has such advantages as high reliability, low cost and high data-transmission-rate. Because of its high practical value, it can be applied in many industrial fields as a basic module.
