Design And Implementation Of Civil Air Traffic Control Scene Visualization System

With the accelerated development of information and data age,various industries have also put forward new demands for data visualization.The development of civil aviation has a high dependence on data and information,how to analyze and display information generated by flight scene has become an important issue to improve management efficiencyAiming at the demand of civil aviation visualization,this thesis studies the ATC(air traffic control).On the process,the data generated and the message used which has been explored in depth.In the end,the thesis implement an ATC Scene Visualization system based on message and data in ATC.The system is divided into three parts: data processing,server and client.The data processing includes AFTN,ADS-B,meteorological message and airport surveillance information processing,also includes the alarm analysis and logging module.The server includes system caching,web services,and map services.The main components of the client are map organization,data maintenance and icon or animation rendering.The thesis main contents are as follows:(1)After analyzing the composition,the thesis decide use airport and flight aircraft to display ATC scene.Providing a visual and auxiliary management functions by combination display with icons,animations and text.(2)Research on contemporary procedure on air traffic control,analyze the message used by teamwork with departments.The thesis provide function like data and message process,message content analyze,auto alarm and log record based on the research.(3)To avoid server process data repeatedly,use MongoDB as the system cache and record the history of data transmission.In order to solve the problem that the server can’t push data to the client under the HTTP protocol,the WebSocket protocol is used to establish the full-duplex communication.(4)The system use Tornado web server framework to produce an effective web service and use Leaflet geographical map container to make SVG elements can be locate on satellite map for comprehensive function.During test for the system function,and test with National Air Traffic Control Scene Data Simulation System.The results show that the Civil Air Traffic Control Scene Visualization System can provide comprehensive function and clear visualization.And it provide a visualization platform for National Air Traffic Control Scene Data Simulation System.
