Visualization Platform of Telemetry Data For Fault Analysis
Abstract：With the rapid development of domestic commercial aerospace, various new vehicles start flight tests in launch sites. The visualization platform of telemetry data is developed by VC++6.0 to the universal and convenient requirements of flight fault analysis in launch sites. It displays the simulation of flight and draws the key telemetry data dynamically in one viewed page, which connects directly the path and attitude of the vehicle with the key telemetry data. It implements such functionalities as the notation of key fight stages, the computation of local extreme values, the rectangular zooming and the quick analysis tool for all telemetry data, which improves the efficiency of flight fault analysis. It can draw various vehicle model files and set the display interface automatically by the predefined file of telemetry data to enhance its universality. Its axes are computed automatically and can be added to any telemetry data in run time, which dramatically decrease the preparations for the platform. The platform can be deployed and run easily in a notebook computer for various new vehicles.
