Abstract:SOE(Sequence Of Event) is used to analyze fault in order to find the cause of the accident in the DCS(distributed control system). In this paper, an acquisition way of the SOE information is studied, it introduces the general structure of the distributed control system, the software deployment of the SOE acquisition system,the communication way between the controller and the operation station, the design technique of the timing system, and the capturing software in the card. This paper focuses on the algorithm through which acquiring the time label of the SOE and the tag positioning method. The acquisition system has been widely applied to the field of the electric power industry, which has the characteristics of high real-time performance and the reasonable algorithm.
Key words :SOE;DCS(distributed control system);time label

在电力、石化、造纸、水泥等重要工业领域中,DCS分布式控制系统[1]被广泛应用。当在系统联调或生产运行过程中发生停机停车故障,用户需要通过DCS平台获取事故原因,而这些项目的工艺过程复杂、实时性高,一般的报警记录和历史趋势都是记录到秒级,无法用来做出准确的事故原因分析,因此事件顺序记录(Sequence Of Event,SOE)成为DCS系统的必需功能,且分辨率一般要求达到毫秒级。本文从软件角度介绍了一种DCS系统获取SOE信息的采集方法,并详细分析了SOE时间标签的生成算法。
