摘要:
城市轨道交通FAO (全自动运行)系统安全保证工作的内容为：依据系统功能、应用场景及其故障影响等因素，确认安全相关系统的范围及安全功能；对安全相关系统的安全功能展开系统化分析，分配和确定其SIL(安全完整性等级)。以某轨道交通线路FAO系统中综合监控系统为例，探讨充分、合理及可行的安全保证工作，研究安全相关系统满足其SIL需求的安全保证模式。
Abstracts:
The safety assurance work of urban rail transit FAO (fully automatic operation) system includes: to define the safety-related system scope and functions according to factors such as system functionality, application scenario and fault impact; to carry out systematic analysis of the safety functions of the safety-related system and to assign and determine the SIL (safety integrity level). Taking the ISCS (integrated supervisory control system) of certain rail transit line FAO system as an example, the sufficient, reasonable and feasible safety assurance work are discussed, and the safety assurance mode of the safety-related system to meet the safety function SIL requirements is studied.
