摘　　要：分布式的网络型电能质量监控系统有着优良的性能,本文利用近年来发展迅速的嵌入式技术,采用自由软件搭建了一套低成本、高可靠性、高性能的网络型电能质量监控系统,系统采用模块化设计和总线式的接口方式,具有很强的兼容性和扩展性。文章详细介绍了该系统的设计思想以及各个层次的软硬件结构,分析了控制系统的实时性概念,并且针对uClinux嵌入式操作系统实时性较差的缺陷,利用RTAI(Real Time Application Interface)对uClinux的实时性进行了扩展,使uClinux可以应用于硬实时控制领域,拓宽了uClinux操作系统在控制领域中的应用范围。The distributed power quality monitoring and control systems have many advantages. A distributed network power quality monitoring and control system which shows many merits in cost, reliability and performance is developed based on free software and embedded technology. The system is modularized and can be exchanged and extended easily. The paper presents the design principle and the structure of each functional layer in detail and analyzes some important conception in real-time control systems. RTAI（ Real Time Application Interface）which enables uClinux to support hard real-time performance is used to improve the real-time capability for uClinux operation system and to strive for the popularization of uClinux in automation field.
