| Abstract: | 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. |
