相较于国外成熟的可靠性数据收集和处理机制,我国的石油化工SIS可靠性数据的收集和处理工作明显滞后。本文从现场可靠性数据的收集处理现状分析、SIS现场可靠性数据的特点和收集程序、安全仪表可靠性数据管理等方面阐述了安全仪表系统现场可靠性数据的收集及处理方法。 Compared with the mature data collection and processing mechanism abroad, the collection and processing of petrochemical SIS reliability data in China lags behind. In this paper, the collection and processing methods of on-site reliability data of safety instrumented system are expounded from the analysis of the status quo of on-site reliability data collection and processing, the characteristics of SIS field reliability data and collection procedures, and the reliability data management of safety instrumentation.
