Abstract:

In order to solve the problem that the UAV could not fly and work normally because the flight data acquisition is abnormally when the UAV is interfered,the paper shows the anti-interference method in UAV flight data based on the character of VxWorks’ timer technology by analyzing the UAV flight data and traditional anti-interference method。 The paper describe the method how to research and realize the key technology. Through theoretical analyzing and comparing the result of UAV flight data, it shows that the method could solve the anti-interference situation effectively without changing the hardware design and the real-time of the UAV system and can be applied in UAV design. 
