A small fixed-wing unmanned aerial vehicle guidance computer and guidance method

Abstract

The invention discloses a miniature fixed wing unmanned aerial plane guidance computer and a guidance method and belongs to the technical field of unmanned aerial plane control. The guidance computer is composed of a power panel and a control signal processing board. The power panel comprises a power transformation circuit module and a simulation reference voltage module. The control signal processing panel comprises an IO driving module, a simulation signal conditioning module, a digital signal conditioning module and a CPU module. The guidance method of the invention can be compatible with the two tracking modes of vertex tracking and fixed distance tracking. The vertex tracking and fixed distance tracking guidance method adopts a unified form, and two types of tracking guidance modes are realized by only sending a variable value instruction. The invention can automatically switch the tracking mode of the unmanned aerial vehicle according to the change of the ground movement speed, can artificially control the tracking mode according to the remote control instruction, and can improve the tracking efficiency and ensure the security when the unmanned aerial vehicle is switching the tracking mode.

Description

technical field [0001] The invention discloses a guidance computer and a guidance method for a small fixed-wing unmanned aerial vehicle, belonging to the technical field of unmanned aerial vehicle flight control. Background technique [0002] UAV technology has achieved rapid development in the past few decades, and has a very wide range of application prospects in military and civilian fields. In these applications, tracking ground targets is the most basic but challenging task. At the same time, the motion control of UAV has become a key part of the target tracking system. Generally, tracking modes can be divided into two categories: overhead tracking and fixed-distance tracking. Overhead tracking is a tracking mode used by UAVs to periodically fly over targets. This tracking mode can closely track fast-moving ground targets, but there is a risk of being exposed. Fixed-distance tracking is a tracking mode in which the UAV keeps a certain distance from the ground target....

AI Technical Summary

Problems solved by technology

Overhead tracking is a tracking mode used by drones to periodically fly over targets. This tracking mode can closely track fast-moving ground targets, but there is a risk of being exposed

Fixed-distance tracking is a tracking mode in which the UAV keeps a certain distance from the ground target. The advantage of fixed-distance tracking is that the UAV can track the ground target without being detected by it. Suitable for tracking of low speed targets
