The Design And Implementation Of Aero Surveillance Information Processing System Based On Android

Aero surveillance information is generated by air traffic control surveillance devices and describes aerobat status.In the monitoring work of aerobat,aero surveillance information is processed and transmitted to the monitor terminal,and then,air traffic control workers and researchers make corresponding analysis and judgement according to the display results.However,Most of the traditional monitoring work is accomplished by the system running on the computer,which is inconvenient and complex.This paper has designed and implemented an aero surveillance information processing system running on Android mobile terminal in order to help air traffic control workers and researchers analyze aero surveillance information in a more convenient way,and also assist the air traffic control.The system has solved a critical problem of missing frames when drawing large number of aerobat using traditional third-party map SDK and visualizes aerobat data using specialized map module.The system mainly includes info reception module,info parsing module,specialized map module,info display module,info storage module and some other function modules.Info reception module is capable of receiving real-time multi-source aero surveillance information via UDP protocol with the help of I/O multiplexing technology.Info parsing module is able to parse many types of ASTERIX standard aero surveillance information which contains aerobat information.Specialized map module is implemented using Universal Transverse Mercator Projection and Android SurfaceView,and provides translation and zooming of the map.Info display module exhibits aerobat data in original text,parsed text and graphics.In graphical presentation,aerobat are drawn on the map,and users can know about related information of aerobat like flight height and flight speed.Info storage module stores real-time aero surveillance information into SQLite database so that the user can review data later on.The paper has verified that the system meets functional design requiments by sending recorded aero surveillance information.At the same time,with the help of specialized map module,the system has supported smooth display of two thousand aerobat.
