Embodiment Construction

[0034] refer to Figure 1 to Figure 3 , the embodiments of the present invention will be described in detail below. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0035] refer to figure 1 , the frequency and amplitude acquisition method based on UAV flight data in the embodiment of the present invention includes steps S100 to S800.

[0036] Step S100 to step S400 are generally completed by a drone. There is flight control software running on the UAV. The flight control software writes the data into the storage device of the drone, specifically into the log file of the drone. The log file of the drone includes a log data package and a log description package, wherein the log data package records the flight data of the drone, and the log description package records the parsing rules of the log data package.

[0037] Step S100, write the flight data of the drone and the syst...

Abstract

The invention discloses a frequency and amplitude acquisition method, comparison method, analysis method and electronic equipment based on unmanned aerial vehicle flight data. The acquisition method includes: writing the flight data of the drone and the system time corresponding to the flight data into a log data packet and forming a verification log data packet; writing the verification log data packet and the log description packet into log file; verify the verification log data packet according to the verification field; obtain the system time and the flight data from the verification log data packet; The data obtains the frequency and amplitude of the digital signal corresponding to the UAV flight data. The comparison method or analysis method performs comparison or analysis after realizing the above acquisition method. The processor of the electronic device implements the above method. The storage medium stores a computer program executable by a processor to implement the above method. True frequency and amplitude are available.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a frequency and amplitude acquisition method, comparison method, analysis method and electronic equipment based on unmanned aerial vehicle flight data. Background technique [0002] In the prior art, to perform spectrum analysis on the UAV, it is necessary to install corresponding acquisition equipment on the UAV, so as to send the data back to the ground station for analysis. Taking vibration analysis as an example, it is necessary to install an acquisition device for collecting the acceleration perpendicular to the plane direction of the UAV body, and also install microprocessors, data transmission units and other equipment, so what is analyzed at this time is a new vibration system. It's not analyzing the original drone. In such scenarios, these acquisition devices installed on the UAV have changed the UAV, so the spectrum analysis is not the analysis of the ...
