摘要
本文介绍了一种基于ARM9的嵌入式电网故障录波系统前端的研制过程。基于嵌入式系统技
术的电力故障录波系统应用于电网状态的实时监控以及电网故障的记录分析,对于及时发现电
网故障,保障电网正常运行具有十分重要的意义。
录波系统由智能录波前端和后台机,即录波工作站组成,一个录波工作站可以管理多个录
波前端。本文介绍的供电网故障录波系统前端负责录波数据采集、打包和存储等任务,其功能
不包括故障录波数据的分析。数据的分析由功能强大的工作站完成。一台录波前端可以记录36
路模拟量和80路开关量、多台录波前端采用分布式结构并通过以太网连接到录波工作站或远程
调度中心。
论文首先对录波系统的概念和研究历史作了简单的介绍,提出了由后台机和多台录波前端
构成的嵌入式分布录波系统方案,紧接着对录波系统的架构和硬件设计进行了介绍,在此基础
上介绍了录波前端采集板上采集控制器、时间同步控制器和动态录波启动算法的设计。论文还
阐述了控制主板上嵌入式Linux系统的构建和驱动系统的移植编写。论文的最后介绍了录波前端
应用软件的工作流程。
目前,嵌入式故障录波系统前端的硬件设计、调试以及嵌入式Linux系统构建和驱动编写移
植工作已经完成,各功能模块已经添加完毕,上层录波程序也已经设计完成并且通过了初步测
试。

ABSTRACT
This thesis introduces an Embedded Fault Recording System based on ARM9. The usage of
Embedded Fault Recording System is to monitor the state of work and record the fault state
of work. It is absolutely necessary in electronic power fault analysis and work
monitoring.
work fault recording system consists of a background work station and several
recording front end. The function of the device introduced in this thesis includes data acquisition,
packing and storage. Its function does not cover the analysis on the fault recorded data, which is
implemented on the background workstation. One device supports 36 analog signals and 80 digital
signals recording. Several devices connect to a recording server via , making up of a
distributed fault recording system.
Firstly, the thesis introduces the concept of fault record system and the research history on it.,
then brings forward a blue print of a distributed fault recording system based on embedded device. In
ession, the thesis presents the architecture and hardware design of the fault recording system. As
follow, the software design of functional blocks on data acquisition board is described,including data
acquisition control, time synchr
