Embodiment Construction

[0053] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0054] The airborne transmitter is mainly used to realize the image of the codec unit, the modulation, frequency conversion and transmission of telemetry signals. see figure 1 As shown, the airborne transmitter is mainly composed of sequentially connected 10MHz reference signal source module 100', phase-locked loop and oscillator module 200', and mixer module 300'. In order to use the airborne transmitter fault prediction test platform to verify the effectiveness of the UAV fault prediction method, the present invention needs the airborne transmitter to be able to generate faults, and can use measuring instruments to collect fault characteristic parameters, and finally send the collected fault information to Into the fault prediction method, the prediction conclusion is obtained, so as to realize the whole process of verification of ...

Abstract

The invention discloses an unmanned aerial vehicle airborne transmitter fault forecasting method, comprising the steps of generating fault response signals based on an airborne transmitter; acquiring first fault signals from the fault response signals, wherein the first fault signals comprise at least one of a power signal, a frequency signal and a spectrum signal; extracting feature parameters from the first fault signals, wherein the feature parameters comprise a peak bandwidth and / or a phase noise value; and forecasting a fault according to the feature parameters. The invention further discloses an unmanned aerial vehicle airborne transmitter fault forecasting system.

Description

technical field [0001] The invention relates to the technical field of UAV fault prediction, in particular to a UAV fault prediction method and system for an UAV airborne transmitter. Background technique [0002] The radio data link subsystem of the UAV (referred to as the data link system), as an important part of the UAV equipment, is a bridge connecting ground operators and UAVs. As a key component of the data link system, the airborne transmitter completes the modulation and launch tasks of relevant instructions and information. Its health status and whether there are hidden dangers of failure are the key issues that need to be solved before the UAV performs its mission. However, the current prediction methods for the health status of airborne transmitters are not accurate and perfect enough. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fault prediction method and system for UAV airborne transmitters w...
