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

    在電力、石化、造紙、水泥等重要工業(yè)領(lǐng)域中,DCS分布式控制系統(tǒng)[1]被廣泛應(yīng)用。當(dāng)在系統(tǒng)聯(lián)調(diào)或生產(chǎn)運(yùn)行過程中發(fā)生停機(jī)停車故障,用戶需要通過DCS平臺獲取事故原因,而這些項(xiàng)目的工藝過程復(fù)雜、實(shí)時性高,一般的報警記錄和歷史趨勢都是記錄到秒級,無法用來做出準(zhǔn)確的事故原因分析,因此事件順序記錄(Sequence Of Event,SOE)成為DCS系統(tǒng)的必需功能,且分辨率一般要求達(dá)到毫秒級。本文從軟件角度介紹了一種DCS系統(tǒng)獲取SOE信息的采集方法,并詳細(xì)分析了SOE時間標(biāo)簽的生成算法。
