Implementation of Aircraft Track Display System Based on QAR Data
In this paper,the Java ScriptAPI provided by Baidu is used to establish a two-dimensional aircraft track simulation model.The flight data recorded in QAR is combined with IOTDB database,Java Spring,JQuery and other technologies to simulate and analyze historical track.With the advantage of IOTDB in processing time series data,the functions of historical track display,dynamic track display and flight risk analysis are realized,and the clear and intuitive visual interface is provided with convenient operation.In the process of accident investigation and analysis,the track system displayed based on QAR can restore the track information in the flight course of the radar and ADS-B transmission signal failure,so as to provide a basis for accident investigation.
