摘　　要：介绍了一种以TMS320F2812为硬件平台,嵌入式实时操作系统μC/OS-Ⅱ为软件平台的交流采样远程终端设计;详述了采用交流采样技术采集汇流条实时电压、电流和频率等数据,通过32位DSP芯片高性能处理能力实现数据处理;以及μC/OS-Ⅱ在系统中的移植及应用;实验结果表明该系统具有可靠、灵活、易于功能扩展且可缩短软件开发周期等优点,能克服干扰和延迟等问题,实时准确地采集各种交流信号。This article introduces a type of AC sampling remote terminal unit which adopts TMS320F2812 as hardware platform and μC/OS-Ⅱ real time embeded operating system as software platform. The sampling of bus real--time voltage . current, frequency and other data based on the AC samping technique, the data processing based on 32- bits DSP, and the transplantation and application ofμC/OS-Ⅱ are introduced in detail in the article. The experiment rusult indicates that the system whose function can be extended easily is dependeble and flexible, and could be used to cut down development cycle, overcome problems such as intrusion, delay and so on, sample various AC signals real time and accurately.
