Visual and instrument flight program automatic aided design system

Abstract

The invention discloses avisual and instrumentation flight program automatic aided design system. The automatic aided design system comprises an application interface layer, a system middle layer and a platform support layer; the application interface layer comprises a user input data parameter interface, a traditional instrument program design interface and the like; the system middle layer comprises a 2D / 3D presentation layer, a core technology layer and a data service layer; the 2D / 3D presentation layer comprises a 2D / 3D graphic interaction interface, a dialog box management interface and the like; the data service layer comprises a 2D / 3D geometric primitive database, a map information database and a chart information database; the platform support layer mainly uses a CAD platform and other bottom layer support technologies. The invention belongs to the field of computer aided design, and particularly relates to a visual and instrument flight program automatic aided design system which can guarantee airport flight and air traffic control operation safety and meet daily use habits of domestic first-line flight program designers.

Description

technical field [0001] The invention belongs to the field of computer-aided design, and specifically refers to a visual and instrument flight program automation aided design system. Background technique [0002] At present, domestic flight procedure aided design systems include: flight procedure design based on GIS, flight procedure computer aided design system (FPCAD for short) of Civil Aviation North China Air Traffic Management Bureau, and auxiliary flight procedure design system based on MAPINFO or SUPERMAP as the development platform. In 1996, the North China Bureau developed FPCAD, namely "Non-Precision Approach Computer Aided System", and there is no mature product yet. The assisted flight procedure design system based on MAPINFO or SUPERMAP as the development platform is an early product of GIS. The domestically developed flight procedure assisted design methods and systems are all based on scanned maps, and there is a problem of map splicing. Moreover, these aided ...

AI Technical Summary

Problems solved by technology

Advantages of domestic existing technology: The advantages of GIS-based flight program design are that the design process is simple, easy to template, easy to understand, easy to add new functions and design new algorithms; disadvantages: incomplete functions, insufficient human-computer interaction, And it does not provide the functions of unit labeling and auxiliary information labeling

Disadvantages of existing foreign technologies: 1) The standards followed by domestic and foreign flight program design are not completely consistent, and the design results given by foreign systems do not apply to domestic standards; 2) Domestic front-line flight program designers generally use CAD platforms for daily design tools, and the design results of the GIS platform cannot be directly imported into the CAD platform for secondary modification to adapt to domestic standards

Therefore, the practicability of foreign systems in China is not high

[0004] To sum up, there are currently no relatively mature programs based on the actual operating conditions in our country, which can guarantee the safety of airport flight and air traffic control operations, and meet the daily habits of domestic front-line flight program designers. Based on a small number of navigation parameters Visual and instrument flight procedure automation aided design method and system
