| 摘要: |
| 针对气象雷达系统任务过程安全性问题，以基于系统论的事故模型及过程（systems-theoretic accident model and process）理论方法为基础，提出了一种案例激励安全性分析方法。在进近阶段机载气象雷达任务过程中，通过构建系统分层控制结构，识别系统任务过程中存在的不安全控制行为，并辨识与不安全控制行为关联的潜在危险致因；构建安全飞行控制结构模型，以达美航空事故为例，提出安全约束建议控制事故衍变机制来优化模型，以提高系统任务过程安全。以上分析表明，该方法能更全面地识别系统深层危险致因，为机载气象雷达的安全性设计提供技术支持。 |

| Abstract: |
| To solve the task-process-safety problem of airborne weather radar system, a set of case-inspired safety analysis method is proposed based on the STAMP(Systems-Theoretic Accident Model and Process). Taking weather radar system's task process in approaching stage as an example, a hierarchical control structure is constructed to identify unsafe control actions during the task process, and analyze the potential hazard causes associating with unsafe control actions. Then a safe flight control structure model is constructed and the accident case of Delta Airlines is analyzed to optimize the model. The safety of system task process is improved through putting forward the safe constraints which can control the propagation mechanism of accident. It is indicated through the above analysis that the method can comprehensively identify the potential hazard causes of system, and provide technical support for the safety design of airborne weather radar system. |
