摘　　要：故障录波装置是继电保护动作行为的检验者。传统的数字式故障录波装置采用通用计算机技术,数据记录的可靠性依赖高速处理器和旋转部件,可靠性差。装置不适合长期稳定运行。嵌入式系统是嵌入到对象中的专用计算机系统,其可靠性不依赖通用计算机和复杂通用操作系统。提出了嵌入式录波一般框架。从数据采集、存储、通信和操作系统四个方面研究了利用嵌入式技术实现故障录波装置中需要注意的问题及解决方法。最后得出嵌入式技术可以应用到故障录波装置中,提高装置的可靠性。Fault recording devices are the checkers of relays＇ operations. Traditional digital fault recording devices make use of general computer technologies, and their reliability of data recording depends on high speed processors and rotating components. So, traditional digital fault recording devices＇ reliability is poor, and they can＇t fit for long-term operation. An embedded system is the special system embedded in an object. Its reliability does not depend on a general computer and a complex operation system. General framework of embedded recording is proposed. Application of embedded fault recording technology in power system fault recording is discussed in detail from four points of view including data collecting, storage, communication and operation system with observing problems and solutions. Finally, this paper concludes that embedded technology can adopt in fault recording devices to improve their reliability.
