摘　　要：综述安全仪表系统的发展过程;对其主要组成、特点以及其各自要求进行研讨;给出安全仪表系统开发的简化流程;探讨安全仪表系统的经济性分析和仪表选择方法;对安全仪表系统整体生命周期中的计划编制、设计、实施、运行、维护和确认等各阶段活动的关键要求进行了讨论和研究。该研究对安全仪表系统的深入理解有指导作用,并为安全仪表系统的分析、设计、实施、运行和维护等活动提供参考。Evolution of safety instrumented system （SIS） is summarized. Main parts of SIS are detailed as well as their characteristics and requirements. Simplified procedure for the developing of SIS is proposed, and economic analysis and instrument selection of SIS are discussed. Key requirements for each phase activities in overall life cycle of SIS, such as planning, design, engineering, operation and validation, are explored. The research is very helpful to the deep and comprehensive understanding of SIS. It provides reference for the activities such as design, engineering, operation and maintenance of SIS.
