The key technology and simulation of UAV flight monitoring system

Abstract

UAV flight safety is the first issue of the UAV's attention. The establishment of a UAV flight monitoring system not only meets the needs of the army but also has important significance. This paper introduces the development status and trends of aircraft fault prediction and health management at home and abroad. The key technologies of UAV flight monitoring system are analyzed, Including flight state parameters acquisition technology, parameter data real-time analysis technology, system condition monitoring model established and system prediction model establishment, system security model, security model and the prediction model of flight safety online monitoring technology, security model and prediction model of control instruction technology assessment. Small unmanned aircraft motion model is established. The pitching Angle, roll Angle, yaw Angle and engine speed are simulated experiment. At last, the paper introduces the function and the significance of the UAV flight monitoring system.
