摘　　要：事件追忆系统是电厂重要设备运行监测装置,用于记录设备事故产生的原因以及事故前后设备的运行状态。文章以嵌入式系统为核心,设计了一套事故追忆系统,给出了系统硬件总体设计方案,重点介绍了开关量信号和不同类型模拟量信号的处理方法。本系统适用于构建集中监测网络,也可对设备的运行状况进行独立监测。Sequence of Events （SOE） is an important equipment operation monitoring device of power plant. It is used to record the cause of accidents and running status of equipment during the accident. Based on the embedded system as the core, this paper design a set of SOE, the overall design scheme of the hardware system is also given. It introduces emphatically the processing methods of switch quantity signal and different types of analog signal. This system is suitable for the construction of centralized monitoring network, also can monitor the running status of equipment independently.
