| Xi'an Xianyang International Airport is the largest air traffic hub in China's northwest region,and Air Traffic Control(ATC)automation systems play an increasingly important role in daily control work.At present most of the existing ATC automation system is based on Linux operating system,due to the particularity of the system requirements.Because of the demands for reliability of the system's operating environment,most ATC automation systems are running on the Redhat Enterprise Linux AS5 operating system.ATC automation system has an open architecture and distributed computing system architecture,and is widely used in multiple airport for air traffic control.In order to improve the security and efficiency of ATC,the entire civil aviation system should be centered on the ATC automation system.With the development and demand of civil aviation and air traffic control automation system,ATC automation system still has some areas that need improvement in the course of operation,mainly in its practical application.In the actual application process,when the original radar signal passes through various processing mechanisms and appears on the controller radar screen,the aircraft false target,the loss of the aircraft target,etc.often occur.The intensification of these problems not only slows down the development of the civil aviation industry,but also hindered the smooth implementation of the economic construction plan.In order to find out the cause and problem of aircraft loss in timely,an original radar data playback system can be introduced,which can not only playback the flight records of the aircraft,but also view the quality of each original radar data.The system can also be used as a major tool for comparing the normal flight of the aircraft in the future.This paper,based on the actual operation of the regional control center,conducted the following research on the original radar data playback system:1.According to the actual operation of the Xi'an Air Traffic Control Center,a secondary radar original data playback analysis system was designed,the research significance of the system was explained,and the architecture of its internal modules was analyzed and designed theoretically.The paper also pointed out the the main research content.2.The design principles and methods of the secondary radar original data playback analysis system are studied from the perspectives of feasibility,economy,and maintainability.The logical architecture of the system is designed,the design goals of the system are proposed,and the technological difficulties in the playback system design is analyzed.3.In order to solve technical difficulties we proposed a new design idea in the original radar data playback system,and the solutions to the difficulties in hardware,software,and formats are introduced,and analyze of some existing problems is presented.4.According to the actual operation,combined with the design of the original radar data playback system presented in this thesis,the Radar Data Playback and Analyzing Human-machine interface are showed,application of the system and a brief summary is exampled. |
