摘　　要：根据旋转导向钻井系统的需要,设计了一种基于嵌入式实时操作系统的主控制器模块。介绍了主控制器的具体功能,单片机的选型,硬件电路设计和实时操作系统的软件设计。在基于C51的单片机ADUC845上,移植了适合C51系统的嵌入式实时操作系统Small RTOS51,并通过精心设计进程任务和信号量实现了主控制器的全部功能,实时性也满足要求。经实验验证和现场作业,该主控制器在复杂恶劣的井下环境中,可以实现对旋转导向钻井工具稳定可靠的控制,展示出良好的应用前景。A down-hole main controller based on MCU is designed for RSS tools （rotary steerable system）. The detailed functions of the main controller, the selection of MCU, hardware design, and the software design based on RTOS （Real-time Operation System） are introduced. The module utilizes ADUC845 which has a C51 core, and an embedded RTOS,SMALL RTOS51, which is suitable for C51 MCU, is transplanted to implement all the functions needed with proper design of the thread tasks and semaphores. The real-time performance meets the requirement too. Experiments and field applications have proved that this main controller can guarantee steady and stable control of the RSS tool in harsh down-hole environment, which proves it has brilliant application prospects.
