| 摘 要： | 毫秒级的任务调度时延限制了标准Linux操作系统在电力系统微机监控装置中的应用。分析了操作系统自适应域环境Adeos（Adaptive Domain Environment for Operating System）的中断管道机制，利用实时应用接口RTAI（Real—Time Application Interface）对标准Linux操作系统进行实时扩展，并结合Cirrus Losic公司的基于EP9301处理器（ARM920T）的EDB9301工程开发板，设计了具有强实时性能的变电站微机监控装置。依据实时性将系统任务划分为实时任务部分和非实时任务部分，且实时任务和非实时任务通过管道（FIFOs）通信。测试数据显示，系统实时核上实时任务调度延迟在微秒级，可以满足硬实时的要求。
