【摘要】：机场净空被视为机场的生命线,是保障航班安全的基本适航条件,没有良好的净空就无法保障飞行安全。本文参考了国内外关于净空的相关文献和研究成果,针对目前存在的主要问题,依据飞行区技术标准分析推导了净空限制高度的计算方法,并建立了机场净空区域的数学模型；在研究理论的基础上,按照软件工程的理论方法对系统进行了需求分析和设计,初步开发了基于GPS (Global Position System)手持终端的轻量级的机场净空评价系统。该系统利用超图公司的嵌入式地理信息系统开发平台eSupermap中.NET组件进行开发,依据机场净空管理人员的需求,结合地理信息系统处理地理数据的优势,在保证系统稳定、有一定精度并且用户界面友好的前提下,完成了机场跑道与障碍物限制面的参数输入以及根据定位位置得到净空评价信息输出的核心工作流程。具体的功能主要包括：查看机场电子地图、对电子地图进行放大、缩小等操作、净空参数输入、障碍物限制面的范围确定、净空评价信息输出等,并对昆明长水机场和首都机场的情况进行了应用和验证。试验结果表明,基本实现了预期要求,系统性能满足基本需求。本文研究的净空评价数学模型与所实现的基于GPS的移动净空评价系统,对我国民用机场选址优化以机场净空日常管理及评价工作都有非常重要的作用和引领意义。
[Abstract]:Airport clearance is regarded as the lifeline of airport and the basic airworthiness condition to ensure flight safety. In this paper, referring to the relevant literature and research results about clearance at home and abroad, according to the main problems existing at present, according to the technical standard of flying area, the calculation method of the height of clearance limit is deduced. The mathematical model of airport clearance area is established, and the requirement analysis and design of the system are carried out according to the theory and method of software engineering. A lightweight airport clearance evaluation system based on GPS Global Position system is developed. Based on the needs of airport clearance manager and the advantages of GIS processing, the system is developed by using. Net components in the embedded GIS development platform eSupermap of Hypergraph Company, which can ensure the stability of the system. With a certain precision and a friendly user interface, The key work flow of the parameter input of airport runway and obstacle limiting surface and the output of clearance evaluation information according to location position are completed. The specific functions include: checking the airport electronic map, enlarging the electronic map, Reduction operation, clearance parameter input, range determination of obstacle limiting surface, clearance evaluation information output and so on. The application and verification of Kunming Changshui Airport and Capital Airport are carried out. The test results show that the expected requirements are basically achieved. System performance meets basic needs. The mathematical model of clearance evaluation and the mobile clearance evaluation system based on GPS are of great importance to the daily management and evaluation of civil airport clearance in China.
