Abstract

The invention relates to an SIL (Safety Integrity Level) assessment unit of a safety instrument system and mainly solves a problem that in the prior art, a computer system, which is targeted at petrochemical devices and has functions of SIF identification, SIL allocation and SIL verification and the like, does not exist domestically yet. The SIL assessment unit for the safety instrument system is adopted and the unit includes SIFs of any number and SIL selection can be carried out for each SIF. The technical scheme of the assessment system, which has functions of safety requirement specification making, SIL verification, SIL report generation and database management solves the problem comparatively well and is applicable to the field of reliability assessment of a safety instrument system of the petroleum and petrochemical industry.

Description

technical field [0001] The invention relates to a safety instrument system SIL level evaluation unit, which belongs to the field of safety instrument system reliability evaluation in the petroleum and petrochemical industry. Background technique [0002] Safety Instrumented System SIS is a safety-related system composed of instruments, also known as an instrumented safety-related system, or an instrumented system that performs safety functions. The word SIS comes from the IEC61511 standard promulgated by the International Electrotechnical Society in 2003, and its Chinese translation of the safety instrumented system comes from the Chinese petrochemical industry standard SH / T3018-2003. The safety instrumented system is a control system specially used for interlocking in dangerous places and emergency shutdown. The essential difference between it and the DCS and PLC of ordinary process control is that its function is to enable the device to stop safely and be in a safe state ...
