航空地面保障是复杂的非线性系统,是保障航空地面安全的关键。在介绍STAMP的基本理论和模型构建过程基础上,结合航空地面保障实际,构架航空地面保障安全分析模型,将安全问题转化为系统的控制问题,以及时发现潜在危险。选取某型制氧制氮设备停机控制系统进行实例分析,从安全约束缺失出发,确立系统层次控制结构并进行失效原因分析,对事故原因进行总结并与已有方法进行比较,最后提出安全防控措施。结果表明,STAMP模型与航空地面保障契合度高,科学性和可信度好,为航空地面保障安全分析提供了新的思路。
Aviation ground support is a complex non-linear system, which is the key to ensure the safety of aviation ground. Based on the introduction of STAMP basic theory and model building process, combined with the actual ground of aviation ground support, the aeronautical ground safety analysis model is constructed to transform the safety problem into the control problem of the system and to find the potential danger in time. Select a type of nitrogen production equipment downtime control system for example analysis, starting from the lack of safety constraints, the establishment of system-level control structure and analysis of the reasons for the failure of the accident were summarized and compared with the existing methods, and finally proposed safety control Measures. The results show that the STAMP model has a good fit with aviation ground support, good scientificity and credibility, and provides a new idea for the safety analysis of ground support.
