【摘要】：随着经济的飞速发展,国内外航班流量日益增加,空中交通安全管理的评价工作显得愈发重要。国内外对安全评估方法如安全检查表、故障树分析、潜在危险研究等已成功地运用于航空航天、核工业等领域的安全技术管理工作中,这些方法应用于航天领域时取得了很好的效果,对国内外安全研究工作的推动起到了积极的作用。然而,由于方法的局限性,往往只能针对特殊的领域、在特定的环境中使用,当条件发生改变的的时候就失效了,特别对于系统总体安全的评估显得无能为力。 开展对空管一线管制单位的运行安全评估工作是亟需解决的关键问题,而具备一套完善的空中交通服务安全评估体系和评估系统是开展安全评估工作的前提条件。本文首先综述了国内外空中交通安全评估的研究现状,就空中交通安全评估相关原理进行了深入分析,研究了安全评估算法的流程、优缺点和应用中的关键点,然后结合软件工程的思想,结合JavaScript和Java开发了基于故障树理论的空中交通安全评估系统,具有系统管理、安全评估原理、安全评估算法、安全评估系统功能模块等四个模块。系统各功能模块相互独立,体现了软件设计中的“高内聚低耦合”的思想。 基于故障树的原理和分析流程,首先对中国民用航空飞行学院新津分院通用航空直升机训练飞行低空东航线与双流进离场航线之间的运行安全进行了评估,选用基于尾流的分析方法和基于障碍物和最低超障高度OCA的分析方法评估了新津东航线穿越五边的安全性。其次,采用Google Earth的三维模拟飞行功能验证了新津东航线穿越五边的可行性。最后,基于常见的测试方法对基于故障树的空中交通服务安全评估系统进行了测试,包括单元测试以及软件的性能测试,测试的结果与概要说明书中的内容一致,具有良好的鲁棒性和可扩展性。基于故障树理论的空中交通服务安全评估系统为安全评估人员提供了一条通用的可行的评估方法途径,对空中交通管制中心安全运行有着积极的意义。
[Abstract]:With the rapid development of economy, domestic and foreign flight traffic is increasing day by day, the evaluation of air traffic safety management becomes more and more important. Safety assessment methods, such as safety checklists, fault tree analysis and potential hazard studies, have been successfully applied to the safety technology management in aerospace, nuclear industry and other fields at home and abroad. These methods have achieved good results in the field of spaceflight and played a positive role in the promotion of safety research at home and abroad. However, because of the limitation of the method, it can only be used in a special field and in a specific environment. When the conditions change, it will fail, especially for the evaluation of the overall security of the system. It is urgent to solve the key problem of operational safety assessment of air traffic control units, and a complete air traffic service safety assessment system and evaluation system is a prerequisite for safety assessment. Firstly, this paper summarizes the research status of air traffic safety assessment at home and abroad, analyzes the relevant principles of air traffic safety assessment, and studies the flow, advantages and disadvantages of the safety assessment algorithm and the key points in its application. Then combined with the idea of software engineering, combined with JavaScript and Java, an air traffic safety assessment system based on fault tree theory is developed. It has four modules: system management, safety assessment principle, security assessment algorithm and function module of safety assessment system. Each functional module of the system is independent of each other, which embodies the idea of "high cohesion and low coupling" in software design. Based on the principle and analysis flow of fault tree, the operation safety of general aviation helicopter training low-altitude east route and double-flow departure route of Xinjin Branch of China Civil Aviation Flight Institute is evaluated. The security of Xinjin East route through five sides is evaluated by using wake based analysis method and OCA analysis method based on obstacle and minimum obstacle height. Secondly, the feasibility of crossing the five sides is verified by using the three-dimensional simulation flight function of Google Earth. Finally, the air traffic service safety evaluation system based on fault tree is tested based on common test methods, including unit test and software performance test. It has good robustness and scalability. The air traffic service safety assessment system based on fault tree theory provides a general and feasible approach for safety assessment personnel and has positive significance for the safe operation of air traffic control center.
