The Component-Based Development Of Sub-GIS And The Research And Application Of Several Key Technologies On The Automatic System For ATC

The thesis is based on the research and development of MRD2K-JH system. which is a new Air Traffic Control system. In the thesis the design and construction of the MRD2K-JH system are investigated in detailed. With the knowledge of software engineering and the Automatic System for ATC, a lot of studies have been carried out on the model and procedure of software development, and on several key technologies on the automatic system for ATC. The main results are presented in the following:(1)Component-Based development of software: With the knowledge of software engineering, the methods and procedures of software development is discussed in detail. Software reuse techniques have indicated that the reuse of software can shorten the software development circle obviously, improve the quality of the software greatly, and decrease the software development cost. The software reuse technology is considered as a well method to resolve the software crisis. The component-based software is one of the main technologies of the software reusing. With the techniques of component-based development is coming, it changed the model of software development. The development is becoming more open, simple and easy to maintain. It will be even predominant during the complicated system, just like ATC system, etc.(2)The development of component-based Sub-GIS for ATC: Considering the characteristic of the GIS in current (like Arc/Info, Maplnfo, etc.), the GIS is not fit in domain of MRD2K-JH. A sub-GIS for MRD2K-JH is developed, which GUI is based on Unix system. With the technologies of component-based development, the requirement analysis and domain analysis has been carried out. After the system isabstracted and decomposed, the reusable components are created with the principles of component-based development. This is even more complicated procedure. The library of the components is well designed, and many of components are reused. As the reusing of components, the quality of the software has been improved greatly, the software circle is shortened and the costs of software are decreased. Also the system has more excellent performance in real time.(3)The research on telegram address auto-generation of planning airlines: As the requirements and trend of the key technologies on the automatic system for ATC, the telegram address must be generated automatically. In this paper, a new method of realizing telegram address auto-generation is proposed, the experimental result proves it a sound way to generate the telegram address of planning airlines. It has three advantages following: (1)the telegram addresses are all accurate(2)not be limited with the beacons and airlines in the database (3)easy to modify and maintain. It is a valuable automatic technology to be developed and applied in the ATC system.(4)The design of Man Machine Interface for the SDD (Supervise Display Device): Considering the principles of the software engineering and man machine interface, the implement of the MMI based on Unix for SDD is discussed in detail. Many factors are considered, the design of MMI is based on X windows/Motif. Well-designed MMI is very important; it can advance the usability of the system and make it more competitive in the world.The thesis is dissertated around the four aspects, The first part, it gave the background, purpose and signification of MRD2K-JH system development. The second part, it introduced the system structure and function structure of MRD2K-JH system. The third part, it introduced the techniques of the Component-Based Development (CBD), and narrated the methods of abstracting and realizing the components. The fourth part, it introduced the component-based development of the sub-GIS for the ATC. The fifth part, a new method of realizing telegram address auto-generation is proposed. The sixth part, it introduced process of the MMI design for SDD. The last part, it summarized all contents of the thesis.
