摘　　要：嵌入式Linux系统由于不支持硬实时任务,限制了其在电能质量监控系统等高实时性领域中的应用。本文介绍了嵌入式Linux系统的实时性,并利用RTAI(RealTimeApplicationInterface)对嵌入式uClinux系统进行了实时性扩展,将RTAI-Lin-ux双内核系统实际应用于电能质量监控实验平台,并通过与uClinux系统的对比实验验证了该系统的硬实时性能,证明其满足电能监控领域的实时性要求。Embedded Linux operation system does not support hard real-time tasks; that seriously restricts its applications. After analyzing the real-time capability of embedded Linux, this article uses RTAI （Real Time Application Interface ）to enable uClinux to support hard real-time performance and proves the improvement in the experiments. That strives for the popularization of embedded Linux in monitoring and automation fields in electrical power system.
