摘　　要：提出了一种改进的μC/OS-Ⅱ的调度算法,增加了时间片轮转算法,把μC/OS-Ⅱ改造为一个以任务优先级调度为主,时间片轮转调度为辅的实时操作系统。并通过碰撞检测算法和路径规划算法在该系统中的应用研究,表明改进的μC/OS-Ⅱ系统能很好地满足需要,具有良好的实用性。An improved scheduling algorithm of μC/OS-Ⅱ was proposed. By increasing time slice cycle algorithm, μC/OS-Ⅱ was reformed to a real-time system, mainly with assignment priority scheduling and supported by time slice cycle scheduling. After studying the application of collision detecting and route planning algorithm in the system, it is shown that the improved μC/OS-Ⅱ system can meet the demand quite well and has good usability.
